jsc2020e040945 (7/10/2020) --- Copper zirconium antenna metal mesh. The Exposure Experiment of Copper-Zirconium Antenna Metal Mesh to the Space Environment (ExHAM-Antenna Metal Mesh) investigation tests how well an antenna metal mesh, made from copper and zirconium, performs in the space environment in low-Earth orbit (LEO). While in space, the antenna metal mesh is exposed to cosmic rays and atomic oxygen in the LEO space environment - which can degrade antenna performance.
