NASA/JPL-Caltech A NASA spacesuit glove designed for use during spacewalks on the International Space Station is prepared for thermal vacuum testing inside a one-of-a-kind chamber called CITADEL (Cryogenic Ice Testing, Acquisition Development, and Excavation Laboratory) at NASA’s Jet Propulsion Laboratory in Southern California on Nov. 1, 2023.
Part of a NASA spacesuit design called the Extravehicular Mobility Unit, the glove was tested at vacuum and minus 352 degrees Fahrenheit (minus 213 degrees Celsius) — temperatures as frigid as those Artemis III astronauts could experience on the Moon’s South Pole. A team from NASA JPL, NASA’s Johnson Space Center in Houston, and the NASA Engineering and Safety Center have collaborated on testing gloves and boots in CITADEL. Elbow joints are slated for testing next. In addition to spotting vulnerabilities with existing NASA suit designs, the experiments will help the agency prepare criteria for test methods for the next-generation lunar suit — being built by Axiom Space — which NASA astronauts will wear during the Artemis III mission.

Robert Markowitz The four astronauts who will be the first to fly to the Moon under NASA’s Artemis campaign have designed an emblem to represent their mission that references both their distant destination and the home they will return to. The crew unveiled their patch in this April 2, 2025, photo.
The crew explained the patch’s symbolism, and its play on the abbreviation of Artemis II to AII, with the following description: The Artemis II test flight begins when a mighty team launches the first crew of the Artemis generation. This patch designates the mission as “AII,” signifying not only the second major flight of the Artemis campaign, but also an endeavor of discovery that seeks to explore for all and by all. Framed in Apollo 8’s famous Earthrise photo, the scene of the Earth and the Moon represents the dual nature of human spaceflight, both equally compelling: The Moon represents our exploration destination, focused on discovery of the unknown. The Earth represents home, focused on the perspective we gain when we look back at our shared planet and learn what it is to be uniquely human. The orbit around Earth highlights the ongoing exploration missions that have enabled Artemis to set sights on a long-term presence on the Moon and soon, Mars.
Commander Reid Wiseman, pilot Victor Glover, and mission specialist Christina Koch from NASA, and mission specialist Jeremy Hansen from CSA (Canadian Space Agency), will venture around the Moon in 2026 on Artemis II. The 10-day flight will test NASA’s foundational human deep space exploration capabilities, the SLS rocket, Orion spacecraft, for the first time with astronauts. Through Artemis, NASA will send astronauts to explore the Moon for scientific discovery, economic benefits, and build the foundation for the first crewed missions to Mars.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Test flights help airplane and drone manufacturers identify which parts of the aircraft are creating the most noise. Using hundreds of wired microphones makes it an expensive and time-consuming process to improve the design to meet noise requirements. Credit: NASA Airplane manufacturers running noise tests on new aircraft now have a much cheaper option than traditional wired microphone arrays. It’s also sensitive enough to help farmers with pest problems. A commercial wireless microphone array recently created with help from NASA can locate crop-threatening insects by listening for the sounds they make in fields.
Since releasing its first commercial product in 2017, a sensor for wind tunnel testing developed with extensive help from NASA (Spinoff 2020), Interdisciplinary Consulting Corporation (IC2) has doubled its staff and moved to a larger lab and office space to produce its new WirelessArray product. Interested in making its own flight tests more affordable, NASA’s Langley Research Center in Hampton, Virginia, supported this project with Small Business Innovation Research contracts and expert consulting.
Airplanes go through noise testing and require certification that they don’t exceed the noise level set for their body type by the Federal Aviation Administration. When an airplane flies directly overhead, the array collects noise data to build a two-dimensional map of the sound pressure and its source. A custom software package translates that information for the end user.
For previous NASA noise testing, multiple semi-trucks hauled all the sensors, wires, power generators, racks of servers, and other equipment required for one flight test. The setup and teardown took six people three days. By contrast, two people can pack the WirelessArray into a minivan and set it up in a day.
IC2 is working with an entomologist to use acoustic data to listen for high-frequency insect sounds in agricultural settings. Discovering where insects feed on crops will make it possible for farmers to intervene before they do too much damage while limiting pesticide use to those areas. Whether it’s helping planes in the sky meet noise requirements or keeping harmful insects away from crops, NASA technology is finding sound-based solutions for the benefit of all.

With ESA’s EarthCARE satellite and four measuring instruments all working extremely well and fully commissioned, the mission’s ‘first level’ data stream is now freely available.
By combining data from all four instruments, scientists ultimately aim to address a critical Earth science question: how do clouds and aerosols affect the heating and cooling of our atmosphere?
