GPM is a joint mission between NASA and the Japan Aerospace Exploration Agency (JAXA). The Core Observatory will link data from a constellation of current and planned satellites to produce next-generation global measurements of rainfall and snowfall from space. On Feb. 11, the Core Observatory was moved into the spacecraft fairing assembly building and into the Encapsulation Hall. Final inspections and preparations were completed for the installation into the fairing, which began on Feb 13. The fairing is the part of the rocket that will contain the spacecraft at the top of the H-IIA rocket. The encapsulation process for the H-IIA is very different than for most U.S. rockets. For U.S. rockets, the fairing is usually in two pieces that close around the payload like a clamshell. To install the GPM Core Observatory into the fairing of the H-IIA rocket, first the Core Observatory and the Payload Attach Fitting (PAF) are set up in scaffolding in the Encapsulation Hall. Then, the fairing is lifted above and lowered onto the fitting. When only a few feet remain above the final position, stanchions support the fairing while technicians go inside to complete the electrical connections. When this is completed, they remove the stanchions and lower the fairing to its final position, where it is bolted in place. The GPM mission is the first coordinated international satellite network to provide near real-time observations of rain and snow every three hours anywhere on the globe. The GPM Core Observatory anchors this network by providing observations on all types of precipitation. The observatory's data acts as the measuring stick by which partner observations can be combined into a unified data set. The data will be used by scientists to study climate change, freshwater resources, floods and droughts, and hurricane formation and tracking.

Completing a Global Map of Ganymede

Central Africa Appears to Be Completely On Fire

NASA’s Suomi NPP satellite detected thousands of fires burning in central Africa on July 11, 2016. The fires are represented by the multitudes of red dots. Most of the fires burn in grass or cropland. The location, widespread nature, and number of fires suggest that these fires were deliberately set to manage land. Places where traditional plots of open land is not available because the vegetation in the area is dense are the places where "slash and burn" agriculture is practiced most often. These regions include parts of Africa, northern South America, and Southeast Asia, where an abundance of grasslands and rainforests are found. Although most parts of the world outlaw this type of agriculture due to the fact that the smoke from these (or any) fires is a health hazard, the method of agriculture continues because it is the easiest and lowest cost solution to clearing fields for next year's crops. The Suomi NPP satellite is a joint mission between NASA, NOAA and the U.S. Department of Defense. NASA image courtesy Jeff Schmaltz, MODIS Rapid Response Team.

NASA’s Webb Telescope Completes Goddard Testing

NASA’s James Webb Space Telescope has successfully passed the center of curvature test, an important optical measurement of Webb’s fully assembled primary mirror prior to cryogenic testing, and the last test held at NASA's Goddard Space Flight Center in Greenbelt, Maryland, before the spacecraft is shipped to NASA’s Johnson Space Center in Houston for more testing. After undergoing rigorous environmental tests simulating the stresses of its rocket launch, the Webb telescope team at Goddard analyzed the results from this critical optical test and compared it to the pre-test measurements. The team concluded that the mirrors passed the test with the optical system unscathed. “The Webb telescope is about to embark on its next step in reaching the stars as it has successfully completed its integration and testing at Goddard. It has taken a tremendous team of talented individuals to get to this point from all across NASA, our industry and international partners, and academia,” said Bill Ochs, NASA’s Webb telescope project manager. “It is also a sad time as we say goodbye to the Webb Telescope at Goddard, but are excited to begin cryogenic testing at Johnson.” Rocket launches create high levels of vibration and noise that rattle spacecraft and telescopes. At Goddard, engineers tested the Webb telescope in vibration and acoustics test facilities that simulate the launch environment to ensure that functionality is not impaired by the rigorous ride on a rocket into space. Before and after these environmental tests took place, optical engineers set up an interferometer, the main device used to measure the shape of the Webb telescope’s mirror. An interferometer gets its name from the process of recording and measuring the ripple patterns that result when different beams of light mix and their waves combine or “interfere.” Waves of visible light are less than a thousandth of a millimeter long and optics on the Webb telescope need to be shaped and aligned even more accurately than that to work correctly. Making measurements of the mirror shape and position by lasers prevents physical contact and damage (scratches to the mirror). So, scientists use wavelengths of light to make tiny measurements. By measuring light reflected off the optics using an interferometer, they are able to measure extremely small changes in shape or position that may occur after exposing the mirror to a simulated launch or temperatures that simulate the subfreezing environment of space. During a test conducted by a team from Goddard, Ball Aerospace of Boulder, Colorado, and the Space Telescope Science Institute in Baltimore, temperature and humidity conditions in the clean room were kept incredibly stable to minimize fluctuations in the sensitive optical measurements over time. Even so, tiny vibrations are ever-present in the clean room that cause jitter during measurements, so the interferometer is a “high-speed” one, taking 5,000 “frames” every second, which is a faster rate than the background vibrations themselves. This allows engineers to subtract out jitter and get good, clean results on any changes to the mirror's shape.

NASA’s Operation IceBridge Completes Twin Polar Campaigns

Heimdal Glacier in southern Greenland, in an image captured on Oct. 13, 2015, from NASA Langley Research Center's Falcon 20 aircraft flying 33,000 feet above mean sea level. NASA’s Operation IceBridge, an airborne survey of polar ice, recently finalized two overlapping campaigns at both of Earth’s poles. Down south, the mission observed a big drop in the height of two glaciers situated in the Antarctic Peninsula, while in the north it collected much needed measurements of the status of land and sea ice at the end of the Arctic summer melt season. This was the first time in its seven years of operations that IceBridge carried out parallel flights in the Arctic and Antarctic. Every year, the mission flies to the Arctic in the spring and to Antarctica in the fall to keep collect an uninterrupted record of yearly changes in the height of polar ice.

MAVEN Mission Primary Structure Complete

NASA's Mars Atmosphere and Volatile EvolutioN (MAVEN) mission has reached a new milestone. Lockheed Martin has completed building the primary structure of the MAVEN spacecraft at its Space Systems Company facility near Denver. The MAVEN spacecraft is scheduled to launch in November 2013 and will be the first mission devoted to understanding the Martian upper atmosphere. The mission's principal investigator is Bruce Jakosky from the Laboratory for Atmospheric and Space Physics at the University of Colorado. In the photo taken on Sept. 8, technicians from Lockheed Martin are inspecting the MAVEN primary structure following its recent completion at the company’s Composites Lab. The primary structure is cube shaped at 7.5 feet x 7.5 feet x 6.5 feet high (2.3 meters x 2.3 meters x 2 meters high). Built out of composite panels comprised of aluminum honeycomb sandwiched between graphite composite face sheets and attached to one another with metal fittings, the entire structure only weighs 275 pounds (125 kilograms). At the center of the structure is the 4.25 feet (1.3 meters) diameter core cylinder that encloses the hydrazine propellant tank and serves as the primary vertical load-bearing structure. The large tank will hold approximately 3,615 pounds (1640 kilograms) of fuel.

Weld Test Completed for Artemis III Rocket Core Stage Tank

The core stage liquid hydrogen tank for the Artemis III mission completed proof testing, and technicians returned it to the main factory building at NASA’s Michoud Assembly Facility in New Orleans where it will undergo more outfitting. As part of proof testing, technicians apply a simple soap solution and check for leaks by observing any bubble formation on the welds. The technician removed the bubble solution with distilled water and then dried the area of application to prevent corrosion. To build the Space Launch System (SLS) rocket’s 130-foot core stage liquid hydrogen tank, engineers use robotic tools to weld five-barrel segments. This process results in a tank with around 1,900 feet, or more than six football fields, of welds that must be tested by hand. After the leak tests, the core stage lead, Boeing, pressurized the SLS tank to further ensure there were no leaks. After it passed proof testing, technicians moved the Artemis III liquid hydrogen tank to Michoud’s main factory. Soon, the technicians will prime and apply a foam-based thermal protection system that protects the tank during launch. Later, the tank will be joined with other parts of the core stage to form the entire 212-foot rocket stage with its four RS-25 engines that produce 2 million pounds of thrust to help launch the rocket. Artemis III will land the first astronauts on the lunar surface.

NASA Completes Webb Telescope Center of Curvature Pre-test

Engineers and technicians working on the James Webb Space Telescope successfully completed the first important optical measurement of Webb’s fully assembled primary mirror, called a Center of Curvature test. Taking a “before” optical measurement of the telescope’s deployed mirror is crucial before the telescope goes into several stages of rigorous mechanical testing. These tests will simulate the violent sound and vibration environments the telescope will experience inside its rocket on its way out into space. This environment is one of the most stressful structurally and could alter the shape and alignment of Webb’s primary mirror, which could degrade or, in the worst case, ruin its performance. Webb has been designed and constructed to withstand its launch environment, but it must be tested to verify that it will indeed survive and not change in any unexpected way. Making the same optical measurements both before and after simulated launch environment testing and comparing the results is fundamental to Webb’s development, assuring that it will work in space.

NASA's Webb "Pathfinder Telescope" Successfully Completes First Super-Cold Optical Test

Testing is crucial part of NASA's success on Earth and in space. So, as the actual flight components of NASA's James Webb Space Telescope come together, engineers are testing the non-flight equipment to ensure that tests on the real Webb telescope later goes safely and according to plan. Recently, the "pathfinder telescope," or just “Pathfinder,” completed its first super-cold optical test that resulted in many first-of-a-kind demonstrations. "This test is the first dry-run of the equipment and procedures we will use to conduct an end-to-end optical test of the flight telescope and instruments," said Mark Clampin, Webb telescope Observatory Project Scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland. "It provides confidence that once the flight telescope is ready, we are fully prepared for a successful test of the flight hardware." The Pathfinder is a non-flight replica of the Webb telescope’s center section backplane, or “backbone,” that includes mirrors. The flight backplane comes in three segments, a center section and two wing-like parts, all of which will support large hexagonal mirrors on the Webb telescope. The pathfinder only consists of the center part of the backplane. However, during the test, it held two full size spare primary mirror segments and a full size spare secondary mirror to demonstrate the ability to optically test and align the telescope at the planned operating temperatures of -400 degrees Fahrenheit (-240 Celsius).

EOC construction update

Work on Stennis Space Center's new Emergency Operations Center is progressing on schedule, according to Robert Perkins, construction manager with Jacobs Technology. At the turn of the New Year, construction contractors had completed the pervious paving for the north and west parking lots. Part of the facility's `green' design, pervious paving allows water to pass through and be absorbed directly into the ground below, preventing erosion from runoff. Through January, workers concentrated on installing the roof, sprinkler piping and overhead cable trays for electrical and communication lines. The next step will be interior work, erecting wallboard and installing electrical equipment. Perkins said NASA seeks to earn a Silver LEED (Leadership in Energy and Environmental Design) Rating for the project's environmentally-friendly and sustainable design, construction and operation. The facility has a projected completion date of February 2009.

NASA’s Wallops Flight Facility Completes Initial Assessment after Orbital Launch Mishap

An aerial view of the Wallops Island launch facilities taken by the Wallops Incident Response Team Oct. 29 following the failed launch attempt of Orbital Science Corp.'s Antares rocket Oct. 28. Credit: NASA/Terry Zaperach --- The Wallops Incident Response Team completed today an initial assessment of Wallops Island, Virginia, following the catastrophic failure of Orbital Science Corp.’s Antares rocket shortly after liftoff at 6:22 p.m. EDT Tuesday, Oct. 28, from Pad 0A of the Mid-Atlantic Regional Spaceport at NASA’s Wallops Flight Facility in Virginia. “I want to praise the launch team, range safety, all of our emergency responders and those who provided mutual aid and support on a highly-professional response that ensured the safety of our most important resource -- our people,” said Bill Wrobel, Wallops director. “In the coming days and weeks ahead, we'll continue to assess the damage on the island and begin the process of moving forward to restore our space launch capabilities. There's no doubt in my mind that we will rebound stronger than ever.” The initial assessment is a cursory look; it will take many more weeks to further understand and analyze the full extent of the effects of the event. A number of support buildings in the immediate area have broken windows and imploded doors. A sounding rocket launcher adjacent to the pad, and buildings nearest the pad, suffered the most severe damage. At Pad 0A the initial assessment showed damage to the transporter erector launcher and lightning suppression rods, as well as debris around the pad. The Wallops team also met with a group of state and local officials, including the Virginia Department of Environmental Quality, the Virginia Department of Emergency Management, the Virginia Marine Police, and the U.S. Coast Guard. The Wallops environmental team also is conducting assessments at the site. Preliminary observations are that the environmental effects of the launch failure were largely contained within the southern third of Wallops Island, in the area immediately adjacent to the pad. Immediately after the incident, the Wallops’ industrial hygienist collected air samples at the Wallops mainland area, the Highway 175 causeway, and on Chincoteague Island. No hazardous substances were detected at the sampled locations. Additional air, soil and water samples will be collected from the incident area as well as at control sites for comparative analysis. The Coast Guard and Virginia Marine Resources Commission reported today they have not observed any obvious signs of water pollution, such as oil sheens. Furthermore, initial assessments have not revealed any obvious impacts to fish or wildlife resources. The Incident Response Team continues to monitor and assess. Following the initial assessment, the response team will open the area of Wallops Island, north of the island flagpole opposite of the launch pad location, to allow the U.S. Navy to return back to work. Anyone who finds debris or damage to their property in the vicinity of the launch mishap is cautioned to stay away from it and call the Incident Response Team at 757-824-1295.

CADRE ATLO Team Presents Completed Rovers

Members of the assembly, test, launch, and operations team for NASA's CADRE (Cooperative Autonomous Distributed Robotic Exploration) project pose in a clean room at the agency's Jet Propulsion Laboratory in Southern California on Jan. 26, 2024, with three lunar rovers after their completion. Bound for the Moon, CADRE is a technology demonstration designed to show that a group of robotic spacecraft can work together as a team to accomplish tasks and record data autonomously – without explicit commands from mission controllers on Earth. Seen behind the rovers are hardware elements that will be mounted on the lunar lander aboard which CADRE will arrive at the Moon: the situational awareness camera assembly (SACA), one of the deployers that will lower the rovers onto the lunar surface, and the base station with which the rovers will communicate via mesh network radios.
