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.

Robert H. Goddard with vacuum tube apparatus he built in 1916 to research rocket efficiency. Dr. Robert Hutchings Goddard is commonly referred to as the father of American rocketry. The same year he built the apparatus, Goddard wrote a study requesting funding from the Smithsonian Institution so that he could continue his rocket research, which he had begun in 1907 while still a student at Worcester Polytechnic Institute. A brilliant physicist, with a unique genius for invention, Goddard may not have succeeded had it not been for the Smithsonian Institution and later the Daniel Guggenheim Foundation and his employer the Worcester Polytechnic Institute of Clark University. The former gave him research monies while the Institute provided leaves of absence so that he could continue his life's work. He was the first scientist who not only realized the potential of missiles and space flight, but also contributed directly to making them a reality. <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.

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.

Electrostatic levitation system inside Electrostatic Levitator (ESL) vacuum chamber. The ESL uses static electricity to suspend an object (about 2-3 mm in diameter) inside a vacuum chamber while a laser heats the sample until it melts. This lets scientists record a wide range of physical properties without the sample contacting the container or any instruments, conditions that would alter the readings. The Electrostatic Levitator is one of several tools used in NASA's microgravity materials science program.

Engineer Paul Reader and his colleagues take environmental measurements during testing of a 20-inch diameter ion engine in a vacuum tank at the Electric Propulsion Laboratory (EPL). Researchers at the Lewis Research Center were investigating the use of a permanent-magnet circuit to create the magnetic field required power electron bombardment ion engines. Typical ion engines use a solenoid coil to create this magnetic field. It was thought that the substitution of a permanent magnet would create a comparable magnetic field with a lower weight. Testing of the magnet system in the EPL vacuum tanks revealed no significant operational problems. Reader found the weight of the two systems was similar, but that the thruster’s efficiency increased with the magnet. The EPL contained a series of large vacuum tanks that could be used to simulate conditions in space. Large vacuum pumps reduced the internal air pressure, and a refrigeration system created the cryogenic temperatures found in space.

Smokeless flame juts from the diffuser of a unique vacuum chamber in which the upper stage rocket engine, the hydrogen fueled J-2, was tested at a simulated space altitude in excess of 60,000 feet. The smoke you see is actually steam. In operation, vacuum is established by injecting steam into the chamber and is maintained by the thrust of the engine firing through the diffuser. The engine was tested in this environment for start, stop, coast, restart, and full-duration operations. The chamber was located at Rocketdyne's Propulsion Field Laboratory, in the Santa Susana Mountains, near Canoga Park, California. The J-2 engine was developed by Rocketdyne for the Marshall Space Flight Center.

NASA's SPHEREx observatory is installed in the Titan Thermal Vacuum (TVAC) test Chamber at BAE Systems in Boulder, Colorado, in June 2024. As part of the test setup, the spacecraft and photon shield are covered in multilayer insulation and blankets and surrounded by ground support equipment. Short for Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer, SPHEREx will create a map of the cosmos like no other. Using a technique called spectroscopy to image the entire sky in 102 wavelengths of infrared light, SPHEREx will gather information about the composition of and distance to millions of galaxies and stars. With this map, scientists will study what happened in the first fraction of a second after the big bang, how galaxies formed and evolved, and the origins of water in planetary systems in our galaxy. https://photojournal.jpl.nasa.gov/catalog/PIA26541

The Orion spacecraft will carry NASA astronauts Victor Glover, Christina Koch, and Reid Wiseman, as well as CSA (Canadian Space Agency) astronaut Jeremy Hansen, on a 10-day journey around the Moon and back for the Artemis II test flight.

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.
