GOES-S Undergoes Thermal Vacuum Testing

By CSA Editor

Online — In March, engineers at Lockheed Martin Space Systems lifted NOAA’s Geostationary Operational Environmental Satellite-S (GOES-S) satellite into a thermal vacuum chamber to begin testing its ability to function in the cold void of space at its orbit 22,300 miles above the Earth.

To simulate the environment of space, researchers removed air from the chamber and cooled it below -100 °C.

Inside the chamber, the satellite will experience four cycles of extreme cold to extreme heat over a period of 45 days. (more…)
