GOES-S satellite in thermal vacuum testing

In March, NOAA's Geostationary Operational Environmental Satellite-S (GOES-S) satellite was lifted into a thermal vacuum chamber to test its ability to function in the cold void of space in its orbit 22,300 miles above the Earth. The most complicated and challenging test is thermal vacuum where a satellite experiences four cycles of extreme cold to extreme heat in a giant vacuum chamber. To simulate the environment of space, the chamber is cooled to below minus 100 degrees Celsius or minus 148 degrees Fahrenheit and air is pumped out. The test simulates the temperature changes GOES-S will encounter in space, as well as worst case scenarios of whether the instruments can come back to life in case of a shut down that exposes them to even colder temperatures. In this photo from March 8, the GOES-S satellite was lowered into the giant vacuum chamber at Lockheed Martin Space Systems, Denver, Colorado. GOES-S will be in the thermal vacuum chamber for 45 days. As of March 30, two of four thermal cycles were complete. GOES-S is the second in the GOES-R series. The GOES-R program is a collaborative development and acquisition effort between the National Oceanic and Atmospheric Administration and NASA. The GOES-R series of satellites will help meteorologists observe and predict local weather events, including thunderstorms, tornadoes, fog, flash floods, and other severe weather. In addition, GOES-R will monitor hazards such as aerosols, dust storms, volcanic eruptions, and forest fires and will also be used for space weather, oceanography, climate monitoring, in-situ data collection, and for search and rescue.

$An engineer prepares the Carbon Mapper imaging spectrometer, which will measure the greenhouse gases methane and carbon dioxide from space, for testing in a thermal vacuum chamber at NASA's Jet Propulsion Laboratory in Southern California in July 2023. This test is one of a series meant to ensure that the instrument can withstand the rigors of launch and the harsh conditions of space. Engineers used the chamber to subject the spectrometer to the extreme temperatures it will encounter in the vacuum of space. The instrument was shipped from JPL to Planet Labs PBC in San Francisco on Sept. 12, 2023, where it will be integrated into a Tanager satellite. Designed and built by JPL, imaging spectrometer will be part of an effort led by the nonprofit Carbon Mapper organization to collect data on greenhouse gas point-source emissions. The information will help locate and quantify "super-emitters" – the small percentage of individual sources responsible for a significant fraction of methane and carbon dioxide emissions around the world. https://photojournal.jpl.nasa.gov/catalog/PIA26094$

NASA's COLDArm in Thermal Vacuum Testing

Engineers and technicians prepare NASA's Cold Operable Lunar Deployable Arm (COLDArm) robotic arm system for testing in a thermal vacuum chamber at the agency's Jet Propulsion Laboratory in Southern California in November 2023. Successful testing in this chamber, which was reduced to minus 292 F (minus 180 C), demonstrates the arm can withstand the conditions it would face on the surface of the Moon. To operate in the cold, COLDArm combines several key new technologies: gears made of bulk metallic glass, which 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, including a 3D-printed titanium scoop that could be used for collecting samples from a celestial body'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/PIA26162

Vacuum Pressure Integrated Suit Test

Engineers and technicians at NASA’s Johnson Space Center in Houston are testing the spacesuit astronauts will wear in the agency’s Orion spacecraft on trips to deep space. On June 22, 2017, members of the Johnson team participated in a Vacuum Pressure Integrated Suit Test to verify enhancements to the suit will meet test and design standards for the Orion spacecraft. During this test, the suit is connected to life support systems and then air is removed from Johnson’s 11-foot thermal vacuum chamber to evaluate the performance of the suits in conditions similar to a spacecraft. The suit will contain all the necessary functions to support life and is being designed to enable spacewalks and sustain the crew in the unlikely event the spacecraft loses pressure.

NASA's Europa Clipper spacecraft is seen in the 85-foot-tall, 25-foot-wide (26-meter-by-8-meter) vacuum chamber, known as the Space Simulator, at the agency's Jet Propulsion Laboratory in Southern California in February 2024. Shortly after this photo was taken, the spacecraft underwent 16 days of thermal vacuum chamber (TVAC) testing so that engineers can be sure the hardware will survive the extreme temperatures and airless environment of space. TVAC is part of a regimen called environmental testing that takes place before spacecraft are approved for flight. Europa Clipper, set to launch in October 2024 from Kennedy Space Center in Florida, will arrive at the Jupiter system in 2030 and conduct about 50 flybys of the moon Europa. The mission's main science goal is to determine whether there are places below the surface of Europa that could support life. The mission's three main science objectives are to determine the thickness of the moon's icy shell and its surface interactions with the ocean below, to investigate its composition, and to characterize its geology. The mission's detailed exploration of Europa will help scientists better understand the astrobiological potential for habitable worlds beyond our planet. https://photojournal.jpl.nasa.gov/catalog/PIA26065

$A technician slides an imaging spectrometer instrument, which will measure the greenhouse gases methane and carbon dioxide from space, into a thermal vacuum test chamber at NASA's Jet Propulsion Laboratory in Southern California in July 2023. The thermal vacuum chamber test is one of a series meant to ensure that the instrument can withstand the rigors of launch and the harsh conditions of space. Engineers use the chamber to subject the spectrometer to the extreme temperatures it will encounter in the vacuum of space. The instrument shipped Sept. 12, 2023, from JPL to Planet Labs PBC in San Francisco, where it will be integrated into a Tanager satellite. Designed and built by JPL, imaging spectrometer will be part of an effort led by the nonprofit Carbon Mapper organization to collect data on greenhouse gas point-source emissions. The information will help locate and quantify "super-emitters" – the small percentage of individual sources responsible for a significant fraction of methane and carbon dioxide emissions around the world.

$The NISAR satellite, partially covered in gold-hued thermal blanketing, enters the thermal vacuum chamber at the Indian Space Research Organisation's Satellite Integration and Test Establishment (ISITE) in Bengaluru, India, on Oct. 19, 2023. Short for NASA-ISRO Synthetic Aperture Radar, NISAR was bound for a 21-day trial aimed at evaluating its ability to function in the extreme temperatures and the vacuum of space. The satellite emerged from the chamber on Nov. 13, having met all requirements of the test. Teams from ISRO and NASA's Jet Propulsion Laboratory worked around the clock, evaluating the performance of the satellite's thermal systems and its two primary science instrument systems – the L-band and S-band radars – under the most extreme temperature conditions they will experience in space. During the three-week period, engineers and technicians lowered the pressure inside the chamber to an infinitesimal fraction of the normal pressure at sea level. They also subjected the satellite to an 80-hour "cold soak" at 14 degrees Fahrenheit (minus 10 degrees Celsius), followed by an equally lengthy "hot soak" at up to 122 F (50 C). This simulates the temperature swings the spacecraft will experience as it is exposed to sunlight and darkness in orbit. After further tests, the satellite will be transported about 220 miles (350 kilometers) eastward to Satish Dhawan Space Centre, where it will be inserted into its launch faring, mounted atop ISRO's Geosynchronous Satellite Launch Vehicle Mark II rocket, and sent into low-Earth orbit. NISAR is the first space-hardware collaboration between NASA and ISRO on an Earth-observing mission. Scheduled to launch in early 2024, the satellite will scan nearly all of the planet's land and ice twice every 12 days, monitoring the motion of those surfaces down to fractions of an inch. It will also track other processes, including the dynamics of forests, wetlands, and agricultural lands. https://photojournal.jpl.nasa.gov/catalog/PIA26114$
