Helene of Troy

Helene Attends Dione

NASA Cassini spacecraft imaged the surface of Saturn moon Helene as the it flew by the moon on Jan. 31, 2011. Helene is a Trojan moon of Dione, named for the Trojan asteroids that orbit 60 degrees ahead of and behind Jupiter as it circles the Sun.

NASA Cassini spacecraft snapped this image during the spacecraft closest flyby of Saturn moon Helene, on March 3, 2010. Helene is a Trojan moon of Dione, named for the Trojan asteroids that orbit ahead of and behind Jupiter.

Cassini came close to Saturn small moon Helene on Feb. 25, 2006, acquiring this high-resolution view. This object seems to be buried in its own crater debris, like another Saturnian moon, Telesto

Although travelling at great speed, NASA Cassini spacecraft managed to capture this close view of Saturn small moon Helene during a flyby on March 3, 2010.

Saturn small, irregularly shaped moon Helene is strikingly illuminated in this close view captured by NASA Cassini during the spacecraft June 18, 2011, flyby.

This set of images exposes details on small and crumpled-looking Helene. Large portions of this Trojan moon of Dione appear to have been blasted away by impacts

This anaglyph, from NASA Shuttle Radar Topography Mission, is of Mount St Helens, Washington. 3D glasses are necessary to view this image.

On May 18, 1980, Mount St. Helens catastrophically erupted, causing the worst volcanic disaster in the recorded history of the United States.

This NASA Terra satellite image of Mount St. Helens was captured one week after the March 8, 2005 ash and steam eruption, the latest activity since the volcano reawakening in September 2004.

This 3-D anaglyph image of Mt. St. Helens volcano combines the nadir-looking and back-looking band 3 images of ASTER. To view the image in stereo, you will need blue-red glasses. Make sure to look through the red lens with your left eye. This ASTER image of Mt. St. Helens volcano in Washington was acquired on August 8, 2000 and covers an area of 37 by 51 km. Mount Saint Helens, a volcano in the Cascade Range of southwestern Washington that had been dormant since 1857, began to show signs of renewed activity in early 1980. On 18 May 1980, it erupted with such violence that the top of the mountain was blown off, spewing a cloud of ash and gases that rose to an altitude of 19 kilometers. The blast killed about 60 people and destroyed all life in an area of some 180 square kilometers (some 70 square miles), while a much larger area was covered with ash and debris. It continues to spit forth ash and steam intermittently. As a result of the eruption, the mountain's elevation decreased from 2,950 meters to 2,549 meters. The image is centered at 46.2 degrees north latitude, 122.2 degrees west longitude. http://photojournal.jpl.nasa.gov/catalog/PIA11160

Mount Saint Helens is a prime example of how Earth topographic form can greatly change even within our lifetimes.

Mount St. Helens, Washington, erupted 40 years ago, on May 18, 1980. A massive debris avalanche, triggered by an earthquake of magnitude 5.1, caused a lateral eruption that reduced the elevation of the mountain's summit from 2,950 m to 2,549 m, leaving a 1.6 km wide horseshoe-shaped crater. The collapse of the northern flank resulted in massive volcanic mudflows. Since 1980, new lava built a dome in the crater, and occasional steam and ash plumes have been emitted. The Landsat MSS image was acquired July 31, 1980, and the ASTER image (Figure 1) on July 28, 2019. The images cover an area of 30 by 30 km, and are located at 46.2 degrees north, 122.2 degrees west. https://photojournal.jpl.nasa.gov/catalog/PIA23913

NASA's Observational Products for End-Users from Remote Sensing Analysis (OPERA) project generated a radar image of Hurricane Helene on Friday, Sept. 26, 2024, at 7:38 p.m. local time, as the storm approached the Florida coast. One of the largest storms to develop in the Gulf of Mexico in the last century, Helene made landfall as a Category 4 hurricane in the Big Bend area of Florida at about 11:10 p.m. The data shown in the image is from the synthetic aperture radar (SAR) instrument on the Copernicus Sentinel-1A satellite, operated by the European Space Agency (ESA), and processed by OPERA into a data product called OPERA RTC-S1. The OPERA RTC-S1 image was converted to a false color image. In this color scale, vegetated areas appear green, urban areas appear white/pink, calm water appears black, and rough water appears purple or magenta. The eye of the hurricane can be clearly seen as a large dark patch in the Gulf of Mexico. The OPERA RTC-S1 image was superimposed on a Google Earth satellite background shown in grayscale and the ESRI Boundaries Places layer. https://photojournal.jpl.nasa.gov/catalog/PIA26414

NASA's Atmospheric Infrared Sounder (AIRS) captured an infrared image of Hurricane Helene on Friday, Sept. 27, 2024, at 3:47 a.m. local time, nearly five hours after it made landfall on the Florida coast. One of the largest storms to develop in the Gulf of Mexico in the last century, Helene made landfall as a Category 4 hurricane in the Big Bend area on Sept. 26, at about 11:10 p.m. In the infrared images, the large purple areas indicate very cold clouds carried high into the atmosphere by deep thunderstorms and associated with heavy rainfall. Warmer areas with shallower rain clouds are shown in blue and green. The orange and red areas represent mostly cloud-free air. The eye of the hurricane can be seen as a small blue dot in the middle of the large purple patch. AIRS, in conjunction with the Advanced Microwave Sounding Unit (AMSU), senses emitted infrared and microwave radiation from Earth to provide a 3D look at Earth'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, the AIRS and AMSU instruments fly onboard NASA's Aqua spacecraft and are managed by NASA's Jet Propulsion Laboratory in Southern California under contract to NASA. JPL is a division of the Caltech. https://photojournal.jpl.nasa.gov/catalog/PIA26413

ISS005-E-18511 (25 October 2002) --- Mount Saint Helens, Washington, is featured in this image photographed by an Expedition 5 crewmember on the International Space Station (ISS). On May 18, 1980, Mount Saint Helens volcano erupted. A series of earthquakes preceded the eruption, triggering a collapse of the north side of the mountain into a massive landslide. This avalanche coincided with a huge explosion that destroyed over 270 square miles of forest in a few seconds, and sent a billowing cloud of ash and smoke 80,000 feet into the atmosphere. The crewmembers on the Station captured this detailed image of the volcano’s summit caldera. In the center of the crater sits a lava dome that is 876 feet above the crater floor and is about 3,500 feet in diameter. The upper slopes of the 1980 blast zone begin at the gray colored region that extends north (upper left) from the summit of the volcano. The deeply incised valley to the left (west) is the uppermost reach of the South Fork of the Toutle River. Devastating mudslides buried the original Toutle River Valley to an average depth of 150 feet, but in places up to 600 feet. The dark green area south of the blast zone is the thickly forested region of the Gifford Pinchot National Forest.

STS078-742-004 (20 June - 7 July 1996) --- This is a north-looking perspective of the major volcanoes of the Cascade Mountains of southern Washington and northern Oregon. With the Earth limb in the upper left corner of the photo, the large mountain at the top right, or northern part of the photo, is Mt. Rainier. The next snow covered area to the south east of Mt. Rainier is Gilbert Point. Mt. Adams is the larger peak, south-southeast of Mt. Rainier, Mt. St. Helens is the gray patch in the center of the photo, west of Mt. Adams. Mt. St. Helens erupted on May 18, 1980, removing 1,300 feet of the 9,677-ft. volcano. The eruption toppled trees with a searing, stone-filled 275-mile-per-hour wind over an area of more than 150 square miles. This area, now referred to as the "blast zone", can be easily spotted in this view. NASA scientists say that natural regrowth of vegetation within the blast zone is progressing at a rapid rate, especially on the outer fringes and in the protected valleys. Many fir trees have grown to heights exceeding 20 feet in a little over 12 years. A large lava dome within the crater of the volcano has grown to a height of over 1,000 feet since the 1980 eruption. The next three snow covered peaks are Mt. Hood, Mt. Jefferson and the Three Sisters all located in Oregon.

Lake Ilopango is a crater lake which fills a volcanic caldera in central El Salvador, immediately east of the capital city San Salvador. The caldera collapsed most recently in about 500 AD, producing 20 times as much ash as the Mount St. Helens eruption, and blanketing an area of at least 10,000 square kilometers waist-deep in ash. The only historical eruption occurred in 1879, forming lava domes, now islets in the lake. Quetzaltepec is the stratovolcano just west of the city. Its last eruption in 1917 produced lavas flowing down the northwest flank, and evaporated the crater lake. The image was acquired March 5, 2006, covers an area of 27 by 42 km, and is located at 13.7 degrees north, 89.1 degrees west. http://photojournal.jpl.nasa.gov/catalog/PIA19237

STS085-716-081 (7-19 August 1997) --- This photograph provides a southerly view from Vancouver, B. C. in the foreground, to Portland, Oregon near the top. Coastal stratus, a common occurrence, hugs the Pacific coastline and laps into Puget sound. The silty Fraser River cuts through Vancouver and empties into Puget Sound with a large, milky plume of sediment (bottom). Near the top of the image, the Columbia River runs across the Cascades (between Mt. Adams and Mt. Hood) and the Coast Ranges to the Pacific Ocean. Snow caps the highest peaks of the Olympic Mountains (near center), and the Cascade volcanoes of Rainier (closest to Seattle), Adams and Hood (top). The smaller, gray mountain just south (above and right) of Rainier is Mt. St. Helens.

NACA staff members queue up in the Lewis Flight Propulsion Laboratory cafeteria in August 1952. The cafeteria originally opened in November 1942 inside the south end of the Engine Research Building. A non-profit Exchange was established to handle the finances, while Helen Thompson, a German born pastry cook, ran the day-to-day operations. Employees could also purchase her bakery to take home with them. Services were expanded to include a lunch counter and a food cart that ferried meals to the facilities. By the end of World War II the cafeteria was serving nearly 1600 meals daily in a space designed for half of that. In 1951 a new wing was added to the Utilities Building to accommodate an expanded cafeteria, seen in this photograph. In the mid-1960s an auxiliary unit was built in the new Development Engineering Building located across Brookpark Road.

Helen Cole, the project manager for the Lab-on-a-Chip Applications Development program, and Lisa Monaco, the project scientist for the program, insert a lab on a chip into the Caliper 42 which is specialized equipment that controls processes on commercial chips to support development of lab-on-a-chip applications. The system has special microscopes and imaging systems, so scientists can process and study different types of fluid, chemical, and medical tests conducted on chips. For example, researchers have examined fluorescent bacteria as it flows through the chips' fluid channels or microfluidic capillaries. Researchers at NASA's Marshall Space Flight Center (MSFC) in Huntsville, Alabama, have been studying how the lab-on-a-chip technology can be used for microbial detection, water quality monitoring, and detecting biosignatures of past or present life on Mars. The Marshall Center team is also collaborating with scientists at other NASA centers and at universities to develop custom chip designs for not only space applications, but for many Earth applications, such as for detecting deadly microbes in heating and air systems.

The ground near one of the long-dormant Three Sisters volcanoes in the Cascade Mountains of west-central Oregon has risen approximately 10centimeters in a 10-by-20-km parcel since 1996, meaning that magma or underground lava is slowly flowing into the area, according to a research team from the U.S. Geological Survey. The Three Sisters area -- which contains five volcanoes -- is only about 170 miles from Mount St. Helens, which erupted in 1980. Both are part of the Cascades Range, a line of 27volcanoes stretching from British Columbia in Canada to northern California. This perspective view was created by draping a simulated natural color ASTER image over digital topography from the U.S. Geological Survey National Elevation Dataset. This image was acquired on May 28, 2000 by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA's Terra satellite. With its 14 spectral bands from the visible to the thermal infrared wavelength region, and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER will image Earth for the next 6 years to map and monitor the changing surface of our planet. http://photojournal.jpl.nasa.gov/catalog/PIA03492

During its examination of Mars, NASA's Viking 1 spacecraft returned images of Valles Marineris, a huge canyon system 5,000 km long, up to 240 km wide, and 6.5 km deep, whose connected chasma or valleys may have formed from a combination of erosional collapse and structural activity. This synthetic oblique view shows Ophir Chasma, the northern most one of the connected valleys of Valles Marineris; north toward top of frame; for scale, the large impact crater in lower right corner is 30 km (18 miles) wide. This point-perspective, digital image, centered at latitude 4 degrees S., longitude 71 degrees, is a composite of Viking 1 Orbiter high-resolution (about 80 m/pixel or picture element) images in black and white and low-resolution (about 250 m/pixel) images in color; no vertical exaggeration. The Viking 1 craft landed on Mars in July of 1976. Ophir Chasma is a large west-northwest-trending trough about 100 km wide. The Chasma is bordered by 4 km high walled cliffs, most likely faults, that show spur-and-gully morphology and smooth sections. The walls have been dissected by landslides forming reentrants; one area (upper left) on the north wall shows a young landslide about 100 km wide. The volume of the landslide debris is more than 1000 times greater than that from the May 18, 1980 debris avalanche from Mount St. Helens. The longitudinal grooves seen in the foreground are thought to be due to differential shear and lateral spreading at high velocities. The landslide passes between mounds of interior layered deposits on the floor of the chasma. http://photojournal.jpl.nasa.gov/catalog/PIA00425
