A team of NASA astronauts will pay a visit to the HST later this year, carrying with them the new WF/PC-2 to replace the one currently on the HST. The Jet Propulsion Laboratory (JPL) in Pasadena, California has been working on the replacement system for several months. See NASA photo S93-33258 for an optical schematic diagram of one of the four channels of the WF\PC-2 showing the path taken by beams from the HST before an image is formed at the camera's charge-coupled devices.

S95-00057 (15 Nov 1994) --- In Rockwell's Building 290 at Downey, California, the external airlock assembly/Mir docking system is rotated into position for crating up for shipment to the Kennedy Space Center (KSC) in Florida. Jointly developed by Rockwell and RSC Energia, the external airlock assembly and Mir docking system will be mounted in the cargo bay of the Space Shuttle Atlantis to enable the shuttle to link up to Russia's Mir space station. The docking system contains hooks and latches compatible with the system currently housed on the Mir's Krystall module, to which Atlantis will attach for the first time next spring. STS-71 will carry two Russian cosmonauts, who will replace a three-man crew aboard Mir including Norman E. Thagard, a NASA astronaut. The combined 10-person crew will conduct almost five days of joint life sciences investigations both aboard Mir and in the Space Shuttle Atlantis's Spacelab module.

The new international satellite mission called Surface Water and Ocean Topography (SWOT) — slated for launch in late 2022 — will measure the height of Earth's surface water. The data the spacecraft will collect will help researchers understand and track the volume and location of water around the world. The satellite will assist with monitoring changes in floodplains and wetlands, measuring how much fresh water flows into and out of lakes and rivers and back to the ocean, and tracking regional shifts in sea level at scales never seen before. The satellite will also provide information on small-scale ocean currents that will support real-time marine operations affected by tides, currents, storm surge, sediment transport, and water quality issues. The payload is taking shape in a clean room at NASA's Jet Propulsion Laboratory in Southern California before being shipped to France. There, technicians and engineers from the French space agency Centre National d'Etudes Spatial (CNES), their prime contractor Thales Alenia Space, and JPL will complete the build and prepare the satellite for shipment to its California launch site at Vandenberg Air Force Base. JPL project manager Parag Vaze (pronounced vah-zay) is central to ensuring the handoff to his CNES counterpart Thierry Lafon goes smoothly. SWOT is being jointly developed by NASA and CNES, with contributions from the Canadian Space Agency (CSA) and United Kingdom Space Agency (UKSA). JPL, which is managed for NASA by Caltech in Pasadena, California, leads the U.S. component of the project. For the flight system, NASA is providing the Ka-band Radar Interferometer (KaRIn) instrument, a GPS science receiver, a laser retroreflector, and a two-beam microwave radiometer. CNES is providing the Doppler Orbitography and Radioposition Integrated by Satellite (DORIS) system, nadir altimeter, and the KaRIn RF subsystem (with support from the UKSA). CSA is providing the KaRIn high-power transmitter assembly. NASA is providing associated launch services. https://photojournal.jpl.nasa.gov/catalog/PIA24531

The Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) twin satellites, attached to turntable fixtures, at the Astrotech Space Operations processing facility at Vandenberg Air Force Base, California. GRACE-FO will extend GRACE's legacy of scientific achievements, which range from tracking mass changes of Earth's polar ice sheets and estimating global groundwater changes, to measuring the mass changes of large earthquakes and inferring changes in deep ocean currents, a driving force in climate. To date, GRACE observations have been used in more than 4,300 research publications. Its measurements provide a unique view of the Earth system and have far-reaching benefits to society, such as providing insights into where global groundwater resources may be shrinking or growing and where dry soils are contributing to drought. GRACE-FO is planned to fly at least five years. https://photojournal.jpl.nasa.gov/catalog/PIA22338

David L. Iverson of NASA Ames Research Center, Moffett Field, California (in foreground) led development of computer software to monitor the conditions of the gyroscopes that keep the International Space Station (ISS) properly oriented in space as the ISS orbits Earth. Also, Charles Lee is pictured. During its develoment, researchers used the software to analyze archived gyroscope records. In these tests, users noticed problems with the gyroscopes long before the current systems flagged glitches. Testers trained using several months of normal space station gyroscope data collected by the International Space Station Mission Control Center at NASA Johnson Space Center, Houston. Promising tests results convinced officials to start using the software in 2007.

In a historic first, all six radio frequency antennas at the Madrid Deep Space Communication Complex – part of NASA's Deep Space Network (DSN) – carried out a test to receive data from the agency's Voyager 1 spacecraft at the same time on April 20, 2024. Known as "arraying," combining the receiving power of several antennas allows the DSN to collect the very faint signals from faraway spacecraft. A five-antenna array is currently needed to downlink science data from the spacecraft's Plasma Wave System (PWS) instrument. As Voyager gets further way, six antennas will be needed. The Voyager team is currently working to fix an issue on the spacecraft that has prevented it from sending back science data since November. Though the antennas located at the DSN's three complexes – Goldstone in California, Canberra in Australia, and Madrid – have been arrayed before, this is the first instance of six antennas being arrayed at once. Madrid is the only deep space communication complex currently with six operational antennas (the other two complexes have four apiece). Each complex consists of one 70-meter (230-foot) antenna and several 34-meter (112-foot) antennas. Voyager 1 is over 15 billion miles (24 billion kilometers) away, so its signal on Earth is far fainter than any other spacecraft with which the DSN communicates. It currently takes Voyager 1's signal over 22 ½ hours to travel from the spacecraft to Earth. To better receive Voyager 1's radio communications, a large antenna – or an array of multiple smaller antennas – can be used. Voyager 1 and its twin, Voyager 2, are the only spacecraft ever to fly in interstellar space (the space between stars). https://photojournal.jpl.nasa.gov/catalog/PIA26147

NASA's Cold Operable Lunar Deployable Arm (COLDArm) robotic arm system reaches out from a lander on the Moon and scoops up regolith (broken rock and dust). Managed by NASA's Jet Propulsion Laboratory in Southern California, COLDArm is designed to operate during lunar night, a period that lasts about 14 Earth days. It can function in temperatures as cold as minus 280 degrees Fahrenheit (minus 173 degrees Celsius). Frigid temperatures during lunar night would stymie the arms on current spacecraft, which must rely on energy-consuming heaters to stay warm. To operate in the cold, the 6-foot-6-inch (2-meter) arm combines several key new technologies: gears made of bulk metallic glass that require no wet lubrication or heating, cold motor controllers that don't need to be kept warm in an electronics box near the core of the spacecraft, and a cryogenic six-axis force torque sensor that lets the arm "feel" what it's doing and make adjustments. A variety of attachments and small instruments could go on the end of the arm, such as a 3D-printed titanium scoop that could collect samples from a planet's surface, similar to what's depicted here. Like the arm on NASA's now-retired InSight Mars lander, COLDArm is also capable of deploying science instruments to the surface. The arm system could be attached to a stationary lander or to a rover. Motiv Space Systems, a partner on COLDArm, developed the cold motor controllers, and also built sections of the arm and assembled it from JPL-supplied parts at the company's Pasadena, California, facility. The COLDArm project is funded through the Lunar Surface Innovation Initiative and managed by the Game Changing Development program in NASA's Space Technology Mission Directorate.

NASA's SMAP (Soil Moisture Active Passive) satellite observatory conducted a field experiment as part of its soil moisture data product validation program in southern Arizona on Aug. 2-18, 2015. The images here represent the distribution of soil moisture over the SMAPVEX15 (SMAP Validation Experiment 2015) experiment domain, as measured by the Passive Active L-band System (PALS) developed by NASA's Jet Propulsion Laboratory, Pasadena, California, which was installed onboard a DC-3 aircraft operated by Airborne Imaging, Inc. Blue and green colors denote wet conditions and dry conditions are marked by red and orange. The black lines show the nominal flight path of PALS. The measurements show that on the first day, the domain surface was wet overall, but had mostly dried down by the second measurement day. On the third day, there was a mix of soil wetness. The heterogeneous soil moisture distribution over the domain is typical for the area during the North American Monsoon season and provides excellent conditions for SMAP soil moisture product validation and algorithm enhancement. The images are based on brightness temperature measured by the PALS instrument gridded on a grid with 0.6-mile (1-kilometer) pixel size. They do not yet compensate for surface characteristics, such as vegetation and topography. That work is currently in progress. http://photojournal.jpl.nasa.gov/catalog/PIA19879

The full-scale engineering model of NASA's Perseverance rover has put some dirt on its wheels. This vehicle system test bed (VSTB) rover moved into its home — a garage facing the Mars Yard at NASA's Jet Propulsion Laboratory in Southern California — on Sept. 4, 2020. It drove onto simulated Martian surface of the Mars Yard — a dirt field at JPL studded with rocks and other obstacles — for the first time on Sept. 8. The VSTB rover is also known as OPTIMISM (Operational Perseverance Twin for Integration of Mechanisms and Instruments Sent to Mars). A key objective for Perseverance's mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will also characterize the planet's climate and geology, pave the way for human exploration of the Red Planet, and be the first planetary spacecraft to collect and cache Martian rock and regolith (broken rock and dust). Subsequent missions, currently under consideration by NASA in cooperation with the European Space Agency, would send spacecraft to Mars to collect these cached samples from the surface and return them to Earth for in-depth analysis. The Mars 2020 mission is part of a larger program that includes missions to the Moon as a way to prepare for human exploration of the Red Planet. Charged with returning astronauts to the Moon by 2024, NASA will establish a sustained human presence on and around the Moon by 2028 through NASA's Artemis lunar exploration plans. https://photojournal.jpl.nasa.gov/catalog/PIA23966

This view of a sandstone target called "Big Arm" covers an area about 1.3 inches (33 millimeters) wide in detail that shows differing shapes and colors of sand grains in the stone. Three separate images taken by the Mars Hand Lens Imager (MAHLI) camera on NASA's Curiosity Mars rover, at different focus settings, were combined into this focus-merge view. The Big Arm target on lower Mount Sharp is at a location near "Marias Pass" where a mudstone bedrock is in contact with overlying sandstone bedrock. MAHLI recorded the component images on May 29, 2015, during the 999th Martian day, or sol, of Curiosity's work on Mars. The rounded shape of some grains visible here suggests they traveled long distances before becoming part of the sediment that later hardened into sandstone. Other grains are more angular and may have originated closer to the rock's current location. Lighter and darker grains may have different compositions. MAHLI was built by Malin Space Science Systems, San Diego. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Mars Science Laboratory Project for the NASA Science Mission Directorate, Washington. http://photojournal.jpl.nasa.gov/catalog/PIA19677

The 3D-printed titanium scoop of the Cold Operable Lunar Deployable Arm (COLDArm) robotic arm system is poised above a test bed filled with material to simulate lunar regolith (broken rocks and dust) at NASA's Jet Propulsion Laboratory in Southern California. COLDArm can function in temperatures as cold as minus 280 degrees Fahrenheit (minus 173 degrees Celsius). COLDArm is designed to go on a Moon lander and operate during lunar night, a period that lasts about 14 Earth days. Frigid temperatures during lunar night would stymie current spacecraft, which must rely on energy-consuming heaters to stay warm. To operate in the cold, the 6-foot-6-inch (2-meter) arm combines several key new technologies: gears made of bulk metallic glass that require no lubrication or heating, cold motor controllers that don't need to be kept warm in an electronics box near the core of the spacecraft, and a cryogenic six-axis force torque sensor that lets the arm "feel" what it's doing and make adjustments. A variety of attachments and small instruments could go on the end of the arm, including the scoop, which could be used for collecting samples from a planet's surface. Like the arm on NASA's InSight Mars lander, COLDArm could deploy science instruments to the surface. https://photojournal.jpl.nasa.gov/catalog/PIA25318

The fire season in California has been anything but cooperative this year. Hot conditions combined with a state-wide drought and dry lightning makes for unpleasant conditions and leads to an abundance of forest fires. On August 12, lightning struck and started the fire that grew into the Happy Camp Complex. Currently over 113,000 acres have been affected and the fire is only 55% contained as of today. Strong winds tested fire lines yesterday (8/15), and are expected to do so again today. Despite the high winds, existing fire lines held with no spotting or expansion outside current containment lines. The south end of the fire continued backing slowly toward Elk Creek in the Marble Mountain Wilderness. The Man Fire joined with the Happy Camp Complex yesterday and will be managed by California Interagency Incident Management Team 4 as of 6:00am on Wednesday, September 17, 2014. Nearby the Happy Camp Complex, near Mt. Shasta and the town of Weed, another fire erupted that fire officials said quickly damaged or destroyed 100 structures Monday (8/15). Hundreds of firefighters were trying to contain that fire. A California Fire spokesman said more than 300 acres were scorched and more than 100 structures damaged or destroyed in just a few hours. The blaze, dubbed the Boles Fire, also led to the closure of Interstate 5 and U.S. 97. Weed is in Siskiyou County, about 50 miles south of the California-Oregon border. With strong winds, the fire was able to rage into the community before firefighters could get equipment to the blaze. About 1,500 to 2,000 residents were being evacuated to the Siskiyou County fairgrounds. An evacuation center was set up at the county fairgrounds in Yreka. NASA's Aqua satellite collected this natural-color image with the Moderate Resolution Imaging Spectroradiometer, MODIS, instrument on September 15, 2014. Actively burning areas, detected by MODIS’s thermal bands, are outlined in red. NASA image courtesy Jeff Schmaltz LANCE/EOSDIS MODIS Rapid Response Team, GSFC.

This collage and animation represent NASA radar observations of near-Earth asteroid 7335 1989 JA on May 26, 2022, one day before it made its closest approach with Earth. The potentially hazardous asteroid came within 2.5 million miles (4 million kilometers) of our planet, or 10.5 times the distance between the Earth and the Moon. Astronomers at NASA's Jet Propulsion Laboratory used the 230-foot (70-meter) radio antenna at the Deep Space Network's Goldstone Deep Space Communications Complex near Barstow, California, to precisely track the asteroid's motion and obtain detailed radar images. 1989 JA is a binary system, consisting of a large asteroid and a significantly smaller satellite asteroid that revolve around each other without touching. The larger asteroid is about 0.4 miles (700 meters) across and shows several topographic features as it rotates. The secondary asteroid, which was discovered this year, is between 100 and 200 meters in diameter and has an orbital period of about 17 hours. 1989 JA was discovered by Eleanor F. Helin at Palomar Observatory in Southern California on May 1, 1989. Follow-up radar observations that year did not reveal a satellite. In 2010, NASA's Wide-field Infrared Survey Explorer (WISE) was used to help determine the primary asteroid's size. This year, a few weeks before the asteroid's most recent close approach, astronomers at Ondrejov Observatory in the Czech Republic measured the asteroid's light curve (the change in reflected light intensity over time) and found hints of the satellite in orbit. The new Goldstone observations refined the size of 1989 JA and established that it is a binary system. 1989 JA does not currently pose an impact risk to Earth, but observations by planetary radar can help astronomers better understand its orbit around the Sun so that any future risk can be continually assessed. https://photojournal.jpl.nasa.gov/catalog/PIA25251

NASA's Atmospheric Infrared Sounder (AIRS) captured Hurricane Hilary on the morning of Aug. 18, 2023, when it was a Category 4 storm roughly 470 miles (760 kilometers) south of Baja California. Hilary could be the first tropical storm to make landfall in California since 1939, according to the National Weather Service. Hilary grew from a tropical storm into a Category 2 hurricane within 24 hours on Aug. 17. Another period of rapid intensification – an increase in maximum sustained wind speed of at least 30 knots (35 mph) within 24 hours – occurred Aug. 17-18. The animation shows some of this rapid growth, with images taken by AIRS Aug. 15-18. This intensification was driven by very warm ocean surface waters and weak wind shear, a term for vertical changes in wind speed. Strong wind shear can keep hurricanes from forming, or can tear them apart. AIRS measures cloud temperatures in infrared wavelengths, which can reveal information about the atmosphere not visible to the human eye. Hilary shows several indicators of a powerful hurricane: a well-defined eye surrounded by a ring of very cold clouds in purple, with warmer outer regions seen in yellows and oranges. Purple and violet areas are colder, between about minus 82 degrees Fahrenheit and minus 46 F (minus 63 degrees Celsius to minus 44 C). Blue and green regions are roughly minus 28 F to 26 F (minus 33 C to minus 3 C). The cooler parts of the clouds are associated with very heavy rainfall. Most hurricanes in the Pacific Ocean off Mexico travel westward, following tropical trade winds. Occasionally, one of these storms will head northward. Hurricane Hilary is being steered by a weak low-pressure system off the coast of California, an area normally dominated by high pressure and an atmospheric circulation pattern that would deflect storms from the region. The current forecast from the National Hurricane Center has Hilary closely following the western coastline of the Baja California peninsula, weakening as it moves north. Rainfall projections for Southern California range from 2 inches (5 centimeters) in coastal areas to 8 or more inches (20 or more centimeters) in local mountains. For comparison, San Diego and Los Angeles receive no rain in August most years, and the wettest parts of the local mountains receive about 1 inch (3 centimeters) of rain over a normal summer. In conjunction with the Advanced Microwave Sounding Unit (AMSU), AIRS senses emitted infrared and microwave radiation from Earth to provide a 3D look at the planet's weather and climate. Working in tandem, the two instruments make simultaneous observations down to Earth's surface. With more than 2,000 channels sensing different regions of the atmosphere, the system creates a global, 3D map of atmospheric temperature and humidity, cloud amounts and heights, greenhouse gas concentrations, and many other atmospheric phenomena. Launched into Earth orbit in 2002 aboard NASA's Aqua spacecraft, the AIRS and AMSU instruments are managed by NASA's Jet Propulsion Laboratory in Southern California, under contract to NASA. JPL is a division of Caltech. Animation available at https://photojournal.jpl.nasa.gov/catalog/PIA25779

NASA-NOAA's Suomi NPP satellite flew over Hurricane Blanca in the Eastern Pacific Ocean and gathered infrared data on the storm that was false-colored to show locations of the strongest thunderstorms within the storm. The Visible Infrared Imaging Radiometer Suite or VIIRS instrument aboard the satellite gathered infrared data of the storm that was made into an image at the University of Wisconsin-Madison. The image was false-colored to show temperature. Coldest cloud top temperatures indicate higher, stronger, thunderstorms within a tropical cyclone. Those are typically the strongest storms with potential for heavy rainfall. VIIRS is a scanning radiometer that collects visible and infrared imagery and "radiometric" measurements. Basically it means that VIIRS data is used to measure cloud and aerosol properties, ocean color, sea and land surface temperature, ice motion and temperature, fires, and Earth's albedo (reflected light). The VIIRS image from June 5 at 8:11 UTC (4:11 a.m. EDT) showed two areas of coldest cloud top temperatures and strongest storms were west-southwest and east-northeast of the center of Blanca's circulation center. On June 5 at 5 a.m. EDT (0900 UTC) Blanca's maximum sustained winds were near 105 mph (165 kph) with higher gusts. The National Hurricane Center (NHC) forecast expects some strengthening during the next day or so. Weakening is forecast to begin by late Saturday. At that time, NHC placed the center of Hurricane Blanca near latitude 14.3 North, longitude 106.2 West. That puts the center about 350 miles (560 km) south-southwest of Manzanillo, Mexico and about 640 miles (1,030 km) south-southeast of Cabo San Lucas, Mexico. The estimated minimum central pressure is 968 millibars (28.59 inches). Blanca is moving toward the northwest near 10 mph (17 kph). A northwestward to north-northwestward motion at a similar forward speed is expected to continue through Saturday night. Blanca has been stirring up surf along the coast of southwestern Mexico and will reach the Pacific coast of the Baja California peninsula and the southern Gulf of California later today, June 5. These swells are likely to cause life-threatening surf and rip current conditions. On the forecast track, the center of Blanca will approach the southern Baja California peninsula on Sunday. NHC cautions that "Interests in the southern Baja California peninsula should monitor the progress of Blanca. A tropical storm or hurricane watch will likely be required for a portion of Baja California Sur later today." The NHC forecast track shows Blanca making landfall in the southeastern tip of Baja California on Sunday, June 7 and tracking north-northeast along the Baja California peninsula, for several days following.

According to the NBCnews.com, Southern California firefighters were battling a growing, brush-fueled wildfire early Friday that had reached the beach in Ventura County and was pushing toward the upscale city of Malibu, officials said. Dubbed the Springs Fire, this "monster" of a wildfire has been made worse by howling Santa Ana winds and unusually dry vegetation. As of 2 am local time in California on Friday the 3rd, it was within "seven or eight miles" of Malibu, Ventura County Fire Department spokesman Bill Nash said. Weather conditions are not cooperating in the containment of this fire. The Weather Channel has predicted dry winds from offshore that will bring gusts of 40 to 50 miles per hour to the Southern California region on Friday the 3rd which could easily spread the fire. A complication to the winds is the extremely dry plant life left from a season in which only about five inches of rain fell in the area. The Springs Fire grew to 10,000 acres and was ten percent contained as of early Friday morning, according to the California Department of Forestry and Fire Prevention. Evacuations took place Thursday, and as of Friday morning 15 homes had been damaged. More than 2,000 homes and 100 commercial properties were under threat from the fire and those numbers could grow with weather conditions today (May 3). Currently the fire is burning in a rural area outside of Malibu, but it doesn't have to go very far to get to some expensive homes and more populated areas. It's current direction has it burning down the mountainside toward Malibu. Firefighters expect to receive help from tankers and helicopters in the air Friday morning, according to a release from the Ventura County Fire Department. The cause of the fire remained under investigation Friday. There had been no lightning or other natural fire-starting phenomenon in the area when the blaze began, Nash said. This natural-color satellite image was collected by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Aqua satellite on May 02, 2013.

Frank Batteas is a research test pilot in the Flight Crew Branch of NASA's Dryden Flight Research Center, Edwards, California. He is currently a project pilot for the F/A-18 and C-17 flight research projects. In addition, his flying duties include operation of the DC-8 Flying Laboratory in the Airborne Science program, and piloting the B-52B launch aircraft, the King Air, and the T-34C support aircraft. Batteas has accumulated more than 4,700 hours of military and civilian flight experience in more than 40 different aircraft types. Batteas came to NASA Dryden in April 1998, following a career in the U.S. Air Force. His last assignment was at Wright-Patterson Air Force Base, Dayton, Ohio, where Lieutenant Colonel Batteas led the B-2 Systems Test and Evaluation efforts for a two-year period. Batteas graduated from Class 88A of the Air Force Test Pilot School, Edwards Air Force Base, California, in December 1988. He served more than five years as a test pilot for the Air Force's newest airlifter, the C-17, involved in nearly every phase of testing from flutter and high angle-of-attack tests to airdrop and air refueling envelope expansion. In the process, he achieved several C-17 firsts including the first day and night aerial refuelings, the first flight over the North Pole, and a payload-to-altitude world aviation record. As a KC-135 test pilot, he also was involved in aerial refueling certification tests on a number of other Air Force aircraft. Batteas received his commission as a second lieutenant in the U. S. Air Force through the Reserve Officer Training Corps and served initially as an engineer working on the Peacekeeper and Minuteman missile programs at the Ballistic Missile Office, Norton Air Force Base, Calif. After attending pilot training at Williams Air Force Base, Phoenix, Ariz., he flew operational flights in the KC-135 tanker aircraft and then was assigned to research flying at the 4950th Test Wing, Wright-Patterson. He flew extensively modified C-135

ISS028-E-035137 (30 Aug. 2011) --- Owens Lake in California is featured in this image photographed by an Expedition 28 crew member on the International Space Station. This photograph highlights the mostly dry bed of Owens Lake, located in the Owens River Valley between the Inyo Mountains and the Sierra Nevada. Shallow groundwater, springs, and seeps support minor wetlands and a central brine pool. Two bright red areas along the margins of the brine pool indicate the presence of halophilic, or salt-loving organisms known as Achaeans. Grey and white materials within the lake bed are exposed lakebed sediments and salt crusts. The towns of Olancha and Lone Pine are delineated by the presence of green vegetation indicating a more constant availability of water. According to scientists, the present-day Owens Lake was part of a much larger lake and river system that existed during the Pleistocene Epoch (approximately 3 million to approximately 12,000 years ago) along the current northeastern border of California with Nevada. Meltwater from alpine glaciers in the Sierra Nevada filled the regional valleys of the Basin and Range to form several glacial lakes that were ancestral to the now-dry lakebeds (or playas) of Owens, Searles Lake, and China Lake. While Searles and China Lakes dried out due to regional changes to a hotter and drier climate over thousands of years, Owens Lake became desiccated largely due to the diversion of Owens River water in the early 20th century to serve the needs of the City of Los Angeles, CA located 266 kilometers to the south. Following complete desiccation of the lakebed in 1926, significant amounts of windblown dust were produced ? indeed, the term ?Keeler fog? was coined by residents of the now largely abandoned town on the eastern side of Owens Lake due to the dust. In addition to adverse health effects on local residents, dust from Owens Lake has been linked to visibility reduction in nearby national parks, forests, and wilderness areas. Recently, efforts to control dust evolution from the lakebed have been undertaken by the City of Los Angeles.

California has been hit hard the past few weeks with storms. Storms bring lightning and lightning strikes cause wildfires. Currently there are at least five fire complexes in the area including River, Fork, South, Route and Mad River. The Mad River complex is a series of seven lightning fires that started on July 30th, 2015 after a lightning storm moved through Northern California. After initial firefighters responded, 25 fires were reported and most of the fires were contained. Some additional fires might be detected from the original lightning storms in the upcoming days and will be attacked once they are found. Damage assessment is ongoing and crews will determine the extent of structures and equipment damaged or destroyed. The River Complex is managing a total of 5 fires due to fires merging together on the Shasta-Trinity and the Six Rivers National Forests. Winds from the west are expected to lift the inversion today resulting in active fire behavior. The Fork Complex consists of over 40 fires, all of which were ignited by lightning between July 29 and 31, 2015. These fires are still being identified, assessed, and prioritized. Updated acreage and information about specific fires will be published as it is known. Fire activity moderated throughout last night (8/4) with the smoke inversion layer remaining in place today. Hopefully this will create favorable conditions for fire crews to take direct fire attack on the fires edge, construct dozer line and scout for best firefighting locations on all fires in the complex. The South Complex consists of approximately nine known fires, five of which are currently over 100 acres. The fires are active and defense of structures and point protection are in progress. The weather is trapping smoke in the valley causing very poor air quality. As the smoke lifts the fire activity increases. Firefighters will continue to provide point protection on structures and to look for opportunities to build direct and indirect containment lines. The Route Complex currently stands at 12,164 acres from seven separate fires and is at 2% containment. The overall acreage has been reduced because the South Fire on the nearby South Complex is merging with the Johnson Fire in the Route Complex resulting in decreased and revised fire perimeter acreage. This natural-color satellite image collected by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Terra satellite shows smoke rising and drifting northwest from the various fire complexes. It was captured on August 04, 2015. Actively burning areas, detected by MODIS’s thermal bands, are outlined in red.

The recently launched Surface Water and Ocean Topography (SWOT) mission collected data on sea levels around two of the inhabited islands of Tuvalu, a nation in the South Pacific Ocean that has been threatened with sea level rise that substantially exceeds the global average. The image shows two areas of red that indicate higher than normal sea levels around two of Tuvalu's inhabited islands, Nanumanga and Nanumea. The higher sea levels were likely caused by internal tides or circular currents called eddies. The SWOT data illuminates for the first time these small ocean features that, when they occur on top of rising sea levels, can lead to episodic flooding along coastlines. The Tuvalu data was collected March 21, 2023. Rising seas are a direct consequence of climate change. On a global scale, the combination of warming ocean waters and ice melt from glaciers and ice sheets is leading to sea level rise that is occurring at an ever-increasing rate. The current rate of rise is more than 0.15 inches (4 millimeters) per year, an increase from 0.08 inches (2 millimeters) per year in 1993. This seemingly small increase holds great significance for coastal communities that have seen more than a century of persistent sea level rise. The gap between the average high tide and flooding conditions has narrowed, and coastal impacts driven by sea level rise have increased in frequency and severity in recent years. This is particularly true for low-lying island nations like Tuvalu, located about 620 miles (1,000 kilometers) north of Fiji. Sea level rise does not occur at the same rate everywhere across the globe, and can be exacerbated by natural ocean fluctuations that occur over time periods from years to decades. For Tuvalu, the amount of sea level rise has been substantially higher than the global average over the past three decades. The amount of rise, when coupled with Tuvalu's low land elevations, places the country increasingly under threat. In the near term, sea level rise will combine with naturally occurring ocean variability and storms to exacerbate events like coastal flooding. Monitoring and understanding sea level change is critical for Tuvalu and other low-lying island nations. Launched on Dec. 16, 2022, from Vandenberg Space Force Base in central California, SWOT collected the Tuvalu sea level data during a period of commissioning, calibration, and validation. Engineers are checking out the performance of the satellite's systems and science instruments before the planned start of science operations in summer 2023. https://photojournal.jpl.nasa.gov/catalog/PIA25777

This satellite image shows smoke from several fires in Oregon and California on Aug. 2, 2015. The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument that flies aboard NASA's Aqua satellite captured an image of smoke from these fires Aug. 2 at 21:05 UTC (5:05 p.m. EDT). The multiple red pixels are heat signatures detected by MODIS. The smoke appears to be a light brown color. InciWeb is an interagency all-risk incident information management system that coordinates with federal, state and local agencies to manage wildfires. In Oregon smoke from the Cable Crossing Fire, the Stouts Fire and the Potter Mountain Complex Fire commingle. The Cable Crossing Fire was reported burning on forestlands protected by the Douglas Forest Protective Association (DFPA) at approximately 3:25 p.m. on Tuesday, July 28, 2015, near Oregon Highway 138 East, near Mile Post 23, east of Glide. South of the Cable Crossing Fire is the Stouts Fire also in forestlands of the DFPA. This fire was reported on Thursday, July 30, 2015, burning approximately 11 miles east of Canyonville near the community of Milo. East of the other fires is the Potter Mountain Complex Fire. These fires are located in the Deschutes Forest consists of eight fires. According to Inciweb they were started by dry lightning on Saturday, Aug. 2, at approximately 5:30 p.m. about five miles north of Toketee Lake. In northern California, smoke from the River Complex Fire, the Fork Complex Fire and the Shf July Lightning Fire was visible in the MODIS image. The River Complex currently consists of seven reported and observed fires on the Six Rivers and Shasta Trinity National Forests. Originally identified as 18 fires, some have burned together. Inciweb noted that in the Six Rivers National Forest there are fires in the Trinity Alps Wilderness. Those fires include the Groves Fire and the Elk Fire. In the Shasta-Trinity National Forest the fires include the Happy Fire at 2,256 acres, Daily Fire at 16 acres, the Look Fire at 7 acres, Onion Fire at 136 acres and Smokey Fire at 1 acre. In the same forest, south of the River Complex is the Fork Complex fire. Inciweb reported that the Fork Complex consists of (at current count) over 40 fires, all of which were ignited by lightning between July 29 and 31, 2015. To the southwest of this complex is the Mad River Complex. This is a series of seven lightning fires that started on July 30, 2015 after a lightning storm moved through Northern California. To the east of this and the other fires, burns another near Redding, California, called the Shf July Lightning Fire. This is also under the Shasta-Trinity National Forest management. At 8 p.m. PDT on Aug. 2, Inciweb reported that approximately 15 lightning strikes occurred within 24 hours throughout the Shasta Trinity National Forest and resulted in two new fires. The Caves fire, east of Mt. Shasta, is approximately one-tenth of an acre. The Bluejay fire, east of Shasta Lake, is approximately four acres.

At first glance a dry lake bed in the southern California desert seems like the last place to prepare to study ice. But on Oct. 2, 2014, NASA’s Operation IceBridge carried out a ground-based GPS survey of the El Mirage lake bed in California’s Mojave Desert. Members of the IceBridge team are currently at NASA’s Armstrong Flight Research Center, preparing instruments aboard the DC-8 research aircraft for flights over Antarctica. Part of this preparation involves test flights over the desert, where researchers verify their instruments are working properly. El Mirage serves as a prime location for testing the mission’s laser altimeter, the Airborne Topographic Mapper, because the lake bed has a flat surface and reflects light similarly to snow and ice. This photo, taken shortly after the survey, shows the GPS-equipped survey vehicle and a stationary GPS station (left of the vehicle) on the lake bed with the constellation Ursa Major in the background. By driving the vehicle in parallel back and forth lines over a predefined area and comparing those GPS elevation readings with measurements from the stationary GPS, researchers are able to build an elevation map that will be used to precisely calibrate the laser altimeter for ice measurements. Credit: NASA/John Sonntag Operation IceBridge is scheduled to begin research flights over Antarctica on Oct. 15, 2014. The mission will be based out of Punta Arenas, Chile, until Nov. 23.

Data from two weather instruments developed at NASA's Jet Propulsion Laboratory in Southern California to provide forecasters data on weather over the open ocean were used to create this image of Tropical Cyclone Mandous on Dec. 9, 2022, as the storm approached the southeastern coast of India. Forecasters at the U.S. Joint Typhoon Warning Center in Pearl Harbor, Hawaii, used the image and others like it to understand the storm's intensity and track its path. The instruments, Compact Ocean Wind Vector Radiometer (COWVR) and Temporal Experiment for Storms and Tropical Systems (TEMPEST), observe the planet's atmosphere and surface from aboard the International Space Station. The image above uses 33.9 gigahertz microwave emissions measured from COWVR to detect structural features of Mandous, including its center, which is about 160 miles (250 kilometers) northeast of the northern tip of Sri Lanka. The colored portions over water indicate the presence of precipitation, with yellow and orange indicating where the storm is strongest, while blue shows where it's weakest. COWVR and TEMPEST sent the data for this image back to Earth in a direct stream via NASA's tracking and data relay satellite (TDRS) constellation. The data was processed at JPL, and meteorologists at the U.S. Naval Research Laboratory in Monterey, California, created the image, which they shared with the Joint Typhoon Warning Center. About the size of a minifridge, COWVR measures natural microwave emissions over the ocean. The magnitude of the emissions increases with the amount of rain in the atmosphere. TEMPEST – comparable in size to a cereal box – tracks microwaves at a much shorter wavelength, allowing it to detect atmospheric water vapor. Both microwave radiometers were conceived to demonstrate that smaller, more energy-efficient, more simply designed sensors can perform most of the same measurements as current space-based weather instruments that are heavier, consume more power, and cost much more to construct. COWVR's development was funded by the U.S. Space Force, and TEMPEST was developed with NASA funding. The U.S. Space Test Program-Houston 8 (STP-H8) is responsible for hosting the instruments on the space station under Space Force funding in partnership with NASA. Data from the instruments is being used by government and university weather forecasters and scientists. The mission will inform development of future space-based weather sensors, and scientists are working on mission concepts that would take advantage of the low-cost microwave sensor technologies to study long-standing questions, such as how heat from the ocean fuels global weather patterns. https://photojournal.jpl.nasa.gov/catalog/PIA25565

The full-scale engineering model of NASA's Perseverance rover raises its "head," or remote sensing mast, at NASA's Jet Propulsion Laboratory in Southern California. This model is known as the vehicle system test bed (VSTB) rover, or OPTIMISM (Operational Perseverance Twin for Integration of Mechanisms and Instruments Sent to Mars). OPTIMISM raised its mast shortly after moving into its new home at JPL's Mars Yard on Sept. 4, 2020. The mast hosts many of the rover's cameras and scientific instruments. At the top of the mast, the large circular opening is where the SuperCam instrument will be installed on this test rover. Also visible in these images below the SuperCam "eye" are the navigation cameras (two cameras closest to the outside of the head) and the Mastcam-Z cameras inside of the navigation cameras. A key objective for Perseverance's mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will also characterize the planet's climate and geology, pave the way for human exploration of the Red Planet, and be the first planetary spacecraft to collect and cache Martian rock and regolith (broken rock and dust). Subsequent missions, currently under consideration by NASA in cooperation with the European Space Agency, would send spacecraft to Mars to collect these cached samples from the surface and return them to Earth for in-depth analysis. The Mars 2020 mission is part of a larger program that includes missions to the Moon as a way to prepare for human exploration of the Red Planet. Charged with returning astronauts to the Moon by 2024, NASA will establish a sustained human presence on and around the Moon by 2028 through NASA's Artemis lunar exploration plans. https://photojournal.jpl.nasa.gov/catalog/PIA23967

Technicians move a full-scale engineering version of NASA's Perseverance Mars rover into to its new home — a garage facing the Mars Yard at the agency's Jet Propulsion Laboratory in Southern California — on Sept. 4, 2020. This vehicle system test bed (VSTB) rover was built in a warehouselike assembly room not far from the Mars Yard — an area that simulates the Red Planet's surface — and enables the mission team to test how hardware and software will perform before they transmit commands to the real rover on Mars. It also goes by the name OPTIMISM (Operational Perseverance Twin for Integration of Mechanisms and Instruments Sent to Mars). The Perseverance rover's astrobiology mission will search for signs of ancient microbial life. It will also characterize the planet's climate and geology, pave the way for human exploration of the Red Planet, and be the first planetary mission to collect and cache Martian rock and regolith (broken rock and dust).

The 3D-printed titanium scoop of the Cold Operable Lunar Deployable Arm (COLDArm) robotic arm system is poised above a test bed filled with material to simulate lunar regolith (broken rocks and dust) at NASA's Jet Propulsion Laboratory in Southern California. COLDArm can function in temperatures as cold as minus 280 degrees Fahrenheit (minus 173 degrees Celsius). Robotics engineer David E. Newill-Smith looks on during testing in September 2022. COLDArm is designed to go on a Moon lander and operate during lunar night, a period that lasts about 14 Earth days. Frigid temperatures during lunar night would stymie current spacecraft, which must rely on energy-consuming heaters to stay warm. To operate in the cold, the 6-foot-6-inch (2-meter) arm combines several key new technologies: gears made of bulk metallic glass that require no lubrication or heating, cold motor controllers that don't need to be kept warm in an electronics box near the core of the spacecraft, and a cryogenic six-axis force torque sensor that lets the arm "feel" what it's doing and make adjustments. A variety of attachments and small instruments could go on the end of the arm, including the scoop, which could be used for collecting samples from a planet's surface. Like the arm on NASA's InSight Mars lander, COLDArm could deploy science instruments to the surface. https://photojournal.jpl.nasa.gov/catalog/PIA25316

A team of NASA researchers from Marshall Space Flight Center (MSFC) and Dryden Flight Research center have proven that beamed light can be used to power an aircraft, a first-in-the-world accomplishment to the best of their knowledge. Using an experimental custom built radio-controlled model aircraft, the team has demonstrated a system that beams enough light energy from the ground to power the propeller of an aircraft and sustain it in flight. Special photovoltaic arrays on the plane, similar to solar cells, receive the light energy and convert it to electric current to drive the propeller motor. In a series of indoor flights this week at MSFC, a lightweight custom built laser beam was aimed at the airplane `s solar panels. The laser tracks the plane, maintaining power on its cells until the end of the flight when the laser is turned off and the airplane glides to a landing. The laser source demonstration represents the capability to beam more power to a plane so that it can reach higher altitudes and have a greater flight range without having to carry fuel or batteries, enabling an indefinite flight time. The demonstration was a collaborative effort between the Dryden Center at Edward's, California, where the aircraft was designed and built, and MSFC, where integration and testing of the laser and photovoltaic cells was done. Laser power beaming is a promising technology for consideration in new aircraft design and operation, and supports NASA's goals in the development of revolutionary aerospace technologies. Photographed with their invention are (from left to right): David Bushman and Tony Frackowiak, both of Dryden; and MSFC's Robert Burdine.

Hurricane Celia is currently in the Eastern Pacific Ocean, but once it passes west of 140 degrees west longitude, warnings on the system will be issued by NOAA's Central Pacific Hurricane Center. On July 11 at 22:05 UTC (6:05 p.m. EDT) the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard NASA-NOAA-DOD's Suomi NPP satellite captured a visible light image of Hurricane Celia that showed a cloud-filled eye with powerful bands of thunderstorms wrapping around the low level center. The VIIRS image also showed a large band of thunderstorms that extended to the south, wrapping into the storms' eastern quadrant. At 5 a.m. EDT (0900 UTC) on July 12 the center of Hurricane Celia was located near 16.2 north latitude and 127.9 west longitude. That's about 1,260 miles (2,025 km) west-southwest of the southern tip of Baja California, Mexico. It was moving to the west-northwest at 10 mph (17 kph) and NOAA's National Hurricane Center (NHC) expects Celia to turn toward the northwest later today, with this motion continuing Tuesday night and Wednesday. Maximum sustained winds were near 100 mph (155 kph). NHC forecasts weakening over the next two days and Celia could weaken to a tropical storm on Wednesday.

The NASA-funded Ground-to-Rocket Electron-Electrodynamics Correlative Experiment, or GREECE, wants to understand aurora. Specifically, it will study classic auroral curls that swirl through the sky like cream in a cup of coffee. The GREECE instruments travel on a sounding rocket that launches for a ten-minute ride right through the heart of the aurora reaching its zenith over the native village of Venetie, Alaska. To study the curl structures, GREECE consists of two parts: ground-based imagers located in Venetie to track the aurora from the ground and the rocket to take measurements from the middle of the aurora itself. At their simplest, auroras are caused when particles from the sun funnel over to Earth's night side, generate electric currents, and trigger a shower of particles that strike oxygen and nitrogen some 60 to 200 miles up in Earth's atmosphere, releasing a flash of light. But the details are always more complicated, of course. Researchers wish to understand the aurora, and movement of plasma in general, at much smaller scales including such things as how different structures are formed there. This is a piece of information, which in turn, helps paint a picture of the sun-Earth connection and how energy and particles from the sun interact with Earth's own magnetic system, the magnetosphere. GREECE is a collaborative effort between SWRI, which developed particle instruments and the ground-based imaging, and the University of California, Berkeley, measuring the electric and magnetic fields. The launch is supported by a sounding rocket team from NASA’s Wallops Flight Facility, Wallops Island, Va. The Poker Flat Research Range is operated by the University of Alaska, Fairbanks.

New imagery from the Hubble Space Telescope is revealing details never before seen on Jupiter. Hubble’s new Jupiter maps were used to create this Ultra HD animation. These new maps and spinning globes of Jupiter were made from observations performed with NASA’s Hubble Space Telescope. They are the first products to come from a program to study the solar system’s outer planets – Jupiter, Uranus, Neptune and, later, Saturn – each year using Hubble. The observations are designed to capture a broad range of features, including winds, clouds, storms and atmospheric chemistry. These annual studies will help current and future scientists see how these giant worlds change over time. Scientists at NASA’s Goddard Space Flight Center, the Jet Propulsion Laboratory, and the University of California at Berkeley produced two global maps of Jupiter from the observations, which were made using Hubble’s high-performance Wide Field Camera 3. The two maps represent nearly back-to-back rotations of the planet, making it possible to determine the speeds of Jupiter’s winds. Already, the images have revealed a rare wave just north of the planet’s equator and a unique filament-like feature in the core of the Great Red Spot that had not been seen previously. In addition, the new images confirm that the Great Red Spot continues to shrink and become more circular, as it has been doing for years. The long axis of this characteristic storm is about 150 miles (240 kilometers) shorter now than it was in 2014. Recently, the storm had been shrinking at a faster-than-usual rate, but the latest change is consistent with the long-term trend.

Two recently launched instruments that were designed and built at NASA's Jet Propulsion Laboratory in Southern California to provide forecasters data on weather over the open ocean captured images of Hurricane Ian on Sept. 27, 2022, as the storm approached Cuba on its way north toward the U.S. mainland. The instruments, Compact Ocean Wind Vector Radiometer (COWVR) and Temporal Experiment for Storms and Tropical Systems (TEMPEST), observe the planet's atmosphere and surface from aboard the International Space Station, which passed in low-Earth orbit over the Caribbean Sea at about 12:30 a.m. EDT. Ian made landfall in Cuba's Pinar del Rio province at 4:30 a.m. EDT, according to the National Hurricane Center. At that time, it was a Category 3 hurricane, with estimated wind speeds of 125 mph (205 kph). The image above combines microwave emissions measurements from both COWVR and TEMPEST. White sections indicate the presence of clouds. Green portions indicate rain. Yellow, red, and black indicate where air and water vapor were moving most swiftly. Ian's center is seen just off of Cuba's southern coast, and the storm is shown covering the island with rain and wind. COWVR and TEMPEST sent the data for this image back to Earth in a direct stream via NASA's tracking and data relay satellite (TDRS) constellation. The data were processed at JPL and made available to forecasters less than two hours after collection. About the size of a minifridge, COWVR measures natural microwave emissions over the ocean. The magnitude of the emissions increases with the amount of rain in the atmosphere, and the strongest rain produces the strongest microwave emissions. TEMPEST – comparable in size to a cereal box – tracks microwaves at a much shorter wavelength, allowing it to see ice particles within the hurricane's cloudy regions that are thrust into the upper atmosphere by the storm. Both microwave radiometers were conceived to demonstrate that smaller, more energy-efficient, more simply designed sensors can perform most of the same measurements as current space-based weather instruments that are heavier, consume more power, and cost much more to construct. COWVR's development was funded by the U.S. Space Force, and TEMPEST was developed with NASA funding. The U.S. Space Test Program-Houston 8 (STP-H8) is responsible for hosting the instruments on the space station under Space Force funding in partnership with NASA. Data from the instruments are being used by government and university weather forecasters and scientists. The mission will inform development of future space-based weather sensors, and scientists are working on mission concepts that would take advantage of the low-cost microwave sensor technologies to study long-standing questions, such as how heat from the ocean fuels global weather patterns. https://photojournal.jpl.nasa.gov/catalog/PIA25425

The GREECE mission studies how certain structures – classic curls like swirls of cream in coffee -- form in the aurora. Credit: NASA/Christopher Perry More info: On March 3, 2014, at 6:09 a.m. EST, a NASA-funded sounding rocket launched straight into an aurora over Venetie, Alaska. The Ground-to-Rocket Electrodynamics – Electron Correlative Experiment, or GREECE, sounding rocket mission, which launched from Poker Flat Research Range in Poker Flat, Alaska, will study classic curls in the aurora in the night sky. The GREECE instruments travel on a sounding rocket that launches for a ten-minute ride right through the heart of the aurora reaching its zenith over the native village of Venetie, Alaska. To study the curl structures, GREECE consists of two parts: ground-based imagers located in Venetie to track the aurora from the ground and the rocket to take measurements from the middle of the aurora itself. At their simplest, auroras are caused when particles from the sun funnel over to Earth's night side, generate electric currents, and trigger a shower of particles that strike oxygen and nitrogen some 60 to 200 miles up in Earth's atmosphere, releasing a flash of light. But the details are always more complicated, of course. Researchers wish to understand the aurora, and movement of plasma in general, at much smaller scales including such things as how different structures are formed there. This is a piece of information, which in turn, helps paint a picture of the sun-Earth connection and how energy and particles from the sun interact with Earth's own magnetic system, the magnetosphere. GREECE is a collaborative effort between SWRI, which developed particle instruments and the ground-based imaging, and the University of California, Berkeley, measuring the electric and magnetic fields. The launch is supported by a sounding rocket team from NASA’s Wallops Flight Facility, Wallops Island, Va. The Poker Flat Research Range is operated by the University of Alaska, Fairbanks. “The conditions were optimal,” said Marilia Samara, principal investigator for the mission at Southwest Research Institute in San Antonio, Texas. “We can’t wait to dig into the data.” For more information on the GREECE mission visit: <a href="http://www.nasa.gov/content/goddard/nasa-funded-sounding-rocket-to-catch-aurora-in-the-act/." rel="nofollow">www.nasa.gov/content/goddard/nasa-funded-sounding-rocket- </a>.<b><a href="http://www.nasa.gov/audience/formedia/features/MP_Photo_Guidelines.html" rel="nofollow">NASA image use policy.</a></b> <b><a href="http://www.nasa.gov/centers/goddard/home/index.html" rel="nofollow">NASA Goddard Space Flight Center</a></b> enables NASA’s mission through four scientific endeavors: Earth Science, Heliophysics, Solar System Exploration, and Astrophysics.
