English: jsc2021e022487 (June 11, 2021) --- NASA’s Exploration Extravehicular Mobility Unit (xEMU) spacesuit undergoes antenna testing in NASA Johnson Space Center’s anechoic chamber to inspect multi-layer insulation keep-out zones for the Wi-Fi and ultra-high-frequency antennas that are part of the spacesuit’s communication system. The xEMU test article is named xGUS, the successor to the Extravehicular Mobility Unit test article (also named GUS), which was named after NASA astronaut Gus Grissom and his iconic silver spacesuit. This image was taken from where the "horn," or source antenna, is located that sends out radio frequency signals to the spacesuit. The anechoic chamber walls are covered with a material that absorbs electromagnetic energy allowing the anechoic chamber to simulate a space environment. The antenna test facility is utilized to test antenna radiation distribution pattern performance for spaceflight applications in electromagnetic environments. |
