IAI ULTRASAT

ULTRASAT, short for Ultraviolet Transient Astronomy Satellite, is a planned Israeli space telescope that will watch the near-ultraviolet sky for short-lived explosive events such as supernovae and the light that follows neutron star mergers. Wikipedia says the spacecraft will be constructed by Israel Aerospace Industries, while the telescope comes from the El-Op division of Elbit Systems, and the mission is funded and managed by the Israel Space Agency and the Weizmann Institute of Science with a contribution from DESY. Gunter's Space Page adds that IAI will also handle mission operations, with the Weizmann Institute running the science operations. At about 160 kg and under one cubic metre it is small enough to ride to geosynchronous orbit as a secondary payload, where it is planned to work for three years after a launch expected in late 2027. The project began in 2010 as a Weizmann and Caltech idea under the name LIMSAT and took its present name in 2011. It has not yet flown.
