The launch of IXPE, an X-tay space telescope launched by NASA and the Italian Space Agency was a bit eclipsed by JWST, but I am sure will help a lot to understand a bit better black holes. It is good news because other space X/R observatories like XMM or Chandra start to be a bit old.
By the way, have you heard of LISA? It is a set of three spacecraft that will be the equivalent of the LIGO project used to detect gravitational waves, but in space.
