At Goddard, the engineers use the Acoustic Test Chamber, a 42-foot-tall chamber, with 6-foot-diameter speaker horns to replicate the launch environment. The horns use an altering flow of gaseous nitrogen to produce a sound level as high as 150 decibels for two-minute tests. That’s about the level of sound heard standing next to a jet engine during takeoff. The 6-foot-wide horns in this 42-foot-tall chamber can produce noise at levels as high as 150 dB. During the acoustics test, the speakers can still be heard outside of its insulated massive metal doors.

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

An Atlas/Centaur mass model undergoes a separation test inside the Space Power Chambers at NASA Lewis Research Center. Lewis was in the midst of an extensive effort to prepare the Centaur second-stage rocket for its missions to send the Surveyor spacecraft to the moon as a precursor to the Apollo missions. As part of these preparations, Lewis management decided to convert its Altitude Wind Tunnel into two large test chambers—the Space Power Chambers. The conversion included the removal of the tunnel’s internal components and the insertion of bulkheads to seal off the new chambers within the tunnel. One chamber could simulate conditions found at 100 miles altitude, while this larger chamber simulated the upper atmosphere. In this test series, researchers wanted to verify that the vehicle’s retrorockets would properly separate the Centaur from the Atlas. The model was suspended horizontally on a trolley system inside chamber. A net was hung at one end to catch the jettisoned Atlas model. The chamber atmosphere was reduced to a pressure altitude of 100,000 feet, and high-speed cameras were synchronized to the ignition of the retrorockets. The simulated Centaur is seen here jettisoning from the Atlas out of view to the right. The study resulted in a new jettison method that would significantly reduce the separation time and thus minimize the danger of collision between the two stages during separation.

Setup of a Surveyor/Atlas/Centaur shroud in the Space Power Chambers for a leak test at the National Aeronautics and Space Administration (NASA) Lewis Research Center. Centaur was a 15,000-pound thrust second-stage rocket designed for the military in 1957 and 1958 by General Dynamics. It was the first major rocket to use the liquid hydrogen technology developed by Lewis in the 1950s. The Centaur Program suffered numerous problems before being transferred to Lewis in 1962. Several test facilities at Lewis’ main campus and Plum Brook Station were built or modified specifically for Centaur, including the Space Power Chambers. In 1961, NASA Lewis management decided to convert its Altitude Wind Tunnel into two large test chambers and later renamed it the Space Power Chambers. The conversion, which took over 2 years, included the removal of the tunnel’s internal components and insertion of bulkheads to seal off the new chambers. The larger chamber, seen here, could simulate altitudes of 100,000 feet. It was used for Centaur shroud separation and propellant management studies until the early 1970s. The leak test in this photograph was likely an attempt to verify that the shroud’s honeycomb shell did not seep any of its internal air when the chamber was evacuated to pressures similar to those found in the upper atmosphere.

A 13-foot diameter mounted inside the large test chamber at the Cryogenic Propellant Tank, or K-Site, at National Aeronautics and Space Administration’s (NASA) Plum Brook Station. The 25-foot test chamber and 20-foot access door were designed to test liquid hydrogen fuel tanks up to 18 feet in diameter in conditions that simulated launches and spaceflight. Shakers were installed to test the effects of launch vibration on the tanks and their insulation. The K Site chamber was also equipped with cold walls that could be cooled with either liquid nitrogen or liquid hydrogen and vacuum pumps that could reduce pressure levels to 10-8 torr. This 13-foot tank passed its initial acceptance tests in K-Site on August 24, 1966. Delays in the modification of the tank postponed further tests of the tank until May 1967. Four pressure hold tests and expulsion runs were made in May using gaseous hydrogen or gaseous helium at 300R and 520R. In June a straight pipe injector test was run and two pressure effect tests at 35 and 75psi. Propellant slosh tests were successfully run in August. This photograph was taken the day after the program’s final runs on September 12, 1967.

A researcher sets up equipment in the Space Power Chamber at National Aeronautics and Space Administration’s (NASA) Plum Brook Station to study the effects of contaminants on clouds. Drs. Rosa and Jorge Pena of Pennsylvania State University's Department of Meteorology initiated the program in an effort to develop methods of creating stable, long-lasting clouds in a test chamber in order to study their composition and formation. The researchers then wanted to use the artificially-created clouds to determine how they were affected by pollution. The 100-foot diameter and 122-foot high Space Power Chamber is the largest vacuum chamber in the world. The researchers covered the circular walls with muslin. A recirculating water system saturated the cloth. The facility engineers then reduced the chamber’s pressure which released the water from the muslin and generated a cloud. The researchers produced five different clouds in this first portion of this study. They discovered that they could not create stable clouds because of the heat generated by the water-pumping equipment. Nonetheless, they felt confident enough to commence planning the second phase of the program using a heat exchanger to cool the equipment.

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.

Preparations for a shroud jettison test for the Orbiting Astronomical Observatory-1 (OAO-1) satellite in the Space Power Chambers facility at the National Aeronautics and Space Administration (NASA) Lewis Research Center. The satellite was to be launched on an Atlas-Agena rocket in the spring of 1966. The 3900-pound payload was the heaviest ever attempted by Agena. The satellite was the first of three equipped with powerful telescopes to study ultraviolet data from specific stars and galaxies. In-depth observations were not possible from Earth-bound telescopes because of the filtering and distortion of the atmosphere. The OAO-1 satellite was wider in diameter than the Agena stage, so a new clamshell shroud was created to enclose both the satellite and the Agena. The clamshell shroud consisted of three sections that enclosed both the Agena and OAO-1: a fiberglass nose fairing and aluminum mid and aft fairings. The upper two fairings separated when the Atlas engines stopped, and the aft fairing fell away with the Atlas upon separation from the upper stages The large altitude tank in the Space Power Chambers could simulate altitudes up to 100,000 feet. Three shroud jettison tests were run in July 1965 and the first week of August at a simulated altitude of 20 miles. The April 8, 1966 launch from Cape Canaveral went smoothly, but the OAO-1 satellite failed after only 90 minutes due to a battery failure.

An astronaut glove designed for use during spacewalks on the International Space Station is prepared for thermal vacuum testing inside a chamber at NASA's Jet Propulsion Laboratory in Southern California on Nov. 1, 2023. The glove lies in a load lock, one of four small drawer-like chambers through which test materials are inserted into the larger main chamber of a facility called CITADEL (Cryogenic Ice Testing, Acquisition Development, and Excavation Laboratory). The glove was tested at vacuum and temperatures as low as minus 352 degrees Fahrenheit (minus 213 degrees Celsius) – temperatures as frigid as those Artemis III astronauts could experience on the Moon's South Pole. Built to prepare potential future robotic spacecraft for the frosty, low-pressure conditions on ocean worlds like Jupiter's frozen moon Europa, CITADEL has also proven key to evaluating how astronaut gloves and boots hold up in extraordinary cold. The NASA Engineering and Safety Center spearheaded a glove testing campaign in CITADEL from October 2023 to March 2024. Part of a spacesuit design called the Extravehicular Mobility Unit, the gloves tested in the chamber are the sixth version of a glove NASA began using in the 1980s. The testing in CITADEL showed that the legacy glove would not meet thermal requirements in the more challenging lunar South Pole environment. In addition to spotting vulnerabilities with existing suits, the CITADEL experiments will help NASA develop this unique test capability and prepare criteria for standardized, repeatable, and inexpensive test methods for the next-generation lunar suit being built by Axiom Space. https://photojournal.jpl.nasa.gov/catalog/PIA26430

The Roman Coronagraph Instrument, a technology demonstration that will be part of NASA's Nancy Grace Roman Space Telescope, is seen amid testing at the agency's Jet Propulsion Laboratory in Southern California in December 2023. During this test in a special isolated, electromagnetically quiet chamber, the instrument was peppered with radio waves to test its response to ensure that the electrical components on the instrument don't interfere with those on the rest of the observatory, and vice versa. The test was performed inside a chamber lined with foam padding that absorbs the radio waves to prevent them from bouncing off the walls. https://photojournal.jpl.nasa.gov/catalog/PIA26273

In a special chamber at NASA's Jet Propulsion Laboratory, engineers prepare to test a small rover that will go to the Moon as part of a NASA technology demonstration called CADRE (Cooperative Autonomous Distributed Robotic Exploration). The project is 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. This electromagnetic interference and compatibility testing took place in November 2023 in a chamber designed to absorb radio waves. Such testing is intended to confirm that the operation of the electronic subsystems do not interfere with each other nor with those on the lander, and that the rover can survive expected electromagnetic disturbances.

The chamber was recently reactivated, after a 24-year hiatus, to perform leak tests on International Space Station pressurized modules at the launch site. Originally, two chambers were built to test Apollo Program flight hardware. They were last used in 1975 during the Apollo-Soyuz Test Project. After installation of new vacuum pumping equipment and controls, a new control room, and a new rotation handling fixture, the chamber again became operational in February 1999. The chamber, which is 33 feet in diameter and 50 feet tall, is constructed of stainless steel. The first module that will be tested for leaks is the U.S. Laboratory. No date has been determined for the test

This video of the Perseverance rover's gDRT (Gaseous Dust Removal Tool) in action was taken during a test in a vacuum chamber at NASA's Jet Propulsion Laboratory in Southern California in August 2020. The tool fires 12-pounds-per-square-inch (about 83 kilopascal) puffs of nitrogen at the tailings and dust that cover a rock after it has been abraded by the rover. Five puffs are required per abrasion – one to vent the tanks and four to clear the abrasion. Animation available at https://photojournal.jpl.nasa.gov/catalog/PIA26578

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

KENNEDY SPACE CENTER, FLA. -- In the Operations and Checkout Building's high bay, the Rotation Handling Fixture (RHF), with a simulated module attached, is lowered by crane into the altitude chamber below during a test. Under normal operation, the RHF will hold a pressurized module intended for the International Space Station, depositing it into the altitude chamber for leak testing. The chamber was recently reactivated after a 24-year hiatus. Originally, two chambers were built to test Apollo Program flight hardware. They were last used in 1975 during the Apollo-Soyuz Test Project. In 1997, in order to increase the probability of successful missions aboard the ISS, NASA decided to perform leak tests on ISS pressurized modules at the launch site. After installation of new vacuum pumping equipment and controls, a new control room, and a new rotation and handling fixture, the chamber again became operational in February 1999. The chamber, which is 33 feet in diameter and 50 feet tall, is constructed of stainless steel. The rotation handling fixture is aluminum. The first module that will be tested for leaks is the U.S. Laboratory. No date has been determined for the test
