In this issue of Contact, we celebrate the completion of necessary treaty ratifications for the SKA Observatory (SKAO) to enter into force. SKA Director-General Prof. Philip Diamond shares his vision for SKAO, and we look back at some of the crucial design work that happened over the past few years, starting with the software development. On the science front, we dive into the world of exobiology, look at the recent achievements of SKA pathfinder facilities like ASKAP, CHIME, GMRT and LOFAR and announce the 2021 SKA Science Conference. Two in-depth interviews with Federico di Vruno (SKAO) on satellite mega-constellations, and Prof. Tao An (Shanghai Astronomical Observatory) on his career complete this bumper edition!
