NASA will launch three suborbital sounding rockets in June and July 2022 from the Arnhem Space Center in Australia’s Northern Territory to conduct astrophysics studies that can only be done from the Southern Hemisphere. The three missions will focus on α Centauri A and B, two of the three-star α Centauri system that are the closest stars to our Sun, and X-rays emanating from the interstellar medium, clouds of gases and particles between stars. The three sounding rocket night-time missions will be launched between June 26 and July 12 on two-stage Black Brant IX sounding rockets, from the Arnhem Space Center, which is owned and operated by Equatorial Launch Australia or ELA. The Arnhem Space Center is a commercial space launch facility, located on the Dhupuma Plateau near Nhulunbuy. The NASA missions will be the first launches from Arnhem.
