New ARISS Antennas Installed on Columbus

Two Amateur Radio on the International Space Station (ARISS) antennas have been installed on the nadir side of the new International Space Station’s Columbus module, set to launch later this year. On October 12, the antennas successfully passed electrical and SWR tests, with one of the two antennas, Antenna 42, going through a final test — a thermal test under vacuum. Based on modeling, engineers have no fear the antenna will pass with flying colors. Columbus will house an additional Amateur Radio station, including the first digital Amateur Radio TV (DATV) station in space, as well as a ham radio transponder. The yet-to-be-built Columbus amateur gear will facilitate operation on new frequencies that will make it possible for ARISS to establish wideband and video operations for the first time and allow continuous transponder operation.
