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.

Research Technology

Researchers at the Marshall Space Flight Center (MSFC) have designed, fabricated, and tested the first solar thermal engine, a non-chemical rocket engine that produces lower thrust but has better thrust efficiency than a chemical combustion engine. MSFC turned to solar thermal propulsion in the early 1990s due to its simplicity, safety, low cost, and commonality with other propulsion systems. Solar thermal propulsion works by acquiring and redirecting solar energy to heat a propellant. The 20- by 24-ft heliostat mirror (not shown in this photograph) has a dual-axis control that keeps a reflection of the sunlight on the 18-ft diameter concentrator mirror, which then focuses the sunlight to a 4-in focal point inside the vacuum chamber. The focal point has 10 kilowatts of intense solar power. This image, taken during the test, depicts the light being concentrated into the focal point inside the vacuum chamber. As part of MSFC's Space Transportation Directorate, the Propulsion Research Center serves as a national resource for research of advanced, revolutionary propulsion technologies. The mission is to move the Nation's capabilities beyond the confines of conventional chemical propulsion into an era of aircraft-like access to Earth orbit, rapid travel throughout the solar system, and exploration of interstellar space.

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

CADRE Team Preps Flight Model for Thermal Testing

Engineers prepare a small rover – part of NASA's CADRE (Cooperative Autonomous Distributed Robotic Exploration) technology demonstration that's headed to the Moon – for testing in the thermal vacuum chamber behind them at the agency's Jet Propulsion Laboratory in Southern California in October 2023. Slated to arrive at the Moon in 2024 as part of NASA's CLPS (Commercial Lunar Payload Services) initiative, CADRE is designed to demonstrate that multiple robots can cooperate and explore together autonomously – without direct input from human mission controllers. A trio of the miniature solar-powered rovers, each about the size of a carry-on suitcase, will explore the Moon as a team, communicating via radio with each other and a base station aboard a lunar lander. By taking simultaneous measurements from multiple locations, CADRE will also demonstrate how multirobot missions can record data impossible for a single robot to achieve – a tantalizing prospect for future missions. The rover being tested is the first flight model to be completed. Thermal vacuum testing simulates the harsh environment the rovers will face on the journey to the Moon and on the lunar surface: All the air is pumped out of the chamber and the temperature is cycled to high and low extremes. https://photojournal.jpl.nasa.gov/catalog/PIA25670

Europa Clipper Rolls Into Thermal Vacuum Testing

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

Orion Spacecraft for Artemis I Prepared for Thermal Test at NASA

NASA’s Orion spacecraft–the crew module and European-built service module—is being lifted on Dec. 1, 2019 into a thermal cage and readied for its move into the vacuum chamber at NASA’s Neil A. Armstrong Test Facility in Ohio (formerly Plum Brook Station) for testing. Testing begins with a 60-day thermal test, where the spacecraft will be subjected to temperatures ranging from -250 to 300-degrees Fahrenheit to ensure it can withstand the harsh environment of space during Artemis missions. These extreme temperatures simulate flying in-and-out of sunlight and shadow in space using Heat Flux, a specially-designed system that heats specific parts of the spacecraft at any given time. Orion will also be surrounded on all sides by a set of large panels, called a cryogenic-shroud, that will provide the cold background temperatures of space.

Stator Blade with Thermal Barrier Testing on Hot Gas Rig

A 1-foot long stator blade with a thermal coating subjected to intense heat in order to test its strength at the National Aeronautics and Space Administration (NASA) Lewis Research Center. Lewis researchers sought to determine optimal types of ceramic coatings to increase the durability of metals. The research was primarily intended to support the design of stator blades for high-performance axial-flow compressor and turbofan engines. The coatings reduced the temperature of the metal and the amount of required cooling. As engines became more and more sophisticated, compressor blades were required to withstand higher and higher temperatures. Lewis researchers developed a dual-layer thermal-barrier coating that could be applied to turbine vanes and blades and combustion liners. This new sprayable thermal-barrier coating was evaluated for its durability, strength, fatigue, and aerodynamic penalties. This hot-gas rig fired the scorching gas at the leading edge of a test blade. The blade was cooled by an internal air flow. The blades were heated at two different velocities during the program. When using Mach 0.3 gases the entire heating and cooling cycle only lasted 30 seconds. The cycle lasted 60 minutes during tests at Mach 1.

OCI Thermal Vacuum Chamber Calibration Testing

Optical engineer, Brendan McAndrew, installs radiometers inside the Ocean Color Instrument (OCI) thermal vacuum chamber in preparation for window calibration testing. The testing will help scientists and engineers know if the optical components of OCI are aligned correctly before it gets integrated to the PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) spacecraft. OCI is a highly advanced optical spectrometer that will be used to measure properties of light over portions of the electromagnetic spectrum. It will enable continuous measurement of light at finer wavelength resolution than previous NASA satellite sensors, extending key system ocean color data records for climate studies. OCI is PACE's (Plankton, Aerosol, Cloud, ocean Ecosystem) primary sensor built at Goddard Space Flight Center in Greenbelt, MD.

$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$

F-15B in flight with X-33 Thermal Protection Systems (TPS) on Flight Test Fixture

In-flight photo of the NASA F-15B used in tests of the X-33 Thermal Protection System (TPS) materials. Flying at subsonic speeds, the F-15B tests measured the air loads on the proposed X-33 protective materials. In contrast, shock loads testing investigated the local impact of the supersonic shock wave itself on the TPS materials. Similar tests had been done in 1985 for the space shuttle tiles, using an F-104 aircraft.

The Mid-Infrared Instrument, a component of NASA James Webb Space Telescope, underwent testing inside the thermal space test chamber at the Science and Technology Facilities Council Rutherford Appleton Laboratory Space in Oxfordshire, England.

The Thermal Protection System (TPS) samples, which included metallic Inconel tiles, soft Advanced Flexible Reusable Surface Insulation tiles, and sealing materials, were attached to the forward-left side position of the test fixture. In-flight video from the aircraft's on-board video system, as well as chase aircraft photos and video footage, documented the condition of the TPS during flights. Surface pressures over the TPS was measured by thermocouples contained in instrumentation "islands," to document shear and shock loads.

Space Science

The Gravity Probe B (GP-B) is the relativity experiment developed at Stanford University to test two extraordinary predictions of Albert Einstein’s general theory of relativity. The experiment will measure, very precisely, the expected tiny changes in the direction of the spin axes of four gyroscopes contained in an Earth-orbiting satellite at a 400-mile altitude. So free are the gyroscopes from disturbance that they will provide an almost perfect space-time reference system. They will measure how space and time are very slightly warped by the presence of the Earth, and, more profoundly, how the Earth’s rotation very slightly drags space-time around with it. These effects, though small for the Earth, have far-reaching implications for the nature of matter and the structure of the Universe. In this photograph, the completed space vehicle is undergoing thermal vacuum environment testing. GP-B is among the most thoroughly researched programs ever undertaken by NASA. This is the story of a scientific quest in which physicists and engineers have collaborated closely over many years. Inspired by their quest, they have invented a whole range of technologies that are already enlivening other branches of science and engineering. Launched April 20, 2004 , the GP-B program was managed for NASA by the Marshall Space Flight Center. Development of the GP-B is the responsibility of Stanford University along with major subcontractor Lockheed Martin Corporation. (Image credit to Russ Underwood, Lockheed Martin Corporation.)

NASA's Lunar Trailblazer Gets a Taste of Space

NASA's Lunar Trailblazer undergoes thermal vacuum chamber (TVAC) testing at Lockheed Martin Space in Littleton, Colorado, in June 2023. The extremely low pressures and temperatures during these tests simulate the conditions that the spacecraft will experience during in space. Lunar Trailblazer, which has a mass of about 440 pounds (200 kilograms) and measures only 11.5 feet (3.5 meters) wide with its solar panels deployed, has now completed TVAC testing and is nearing completion before its planned launch in early 2024. The spacecraft's two science instruments will map the form, abundance, and locations of water in on the lunar surface while also revealing the thermal properties and surface composition of those regions. https://photojournal.jpl.nasa.gov/catalog/PIA25836
