The Space Variable Objects Monitor (SVOM) is a small X-ray telescope satellite developed by China National Space Administration (CNSA), Chinese Academy of Sciences (CAS) and the French Space Agency (CNES),[5] launched on 22 June 2024 (07:00:00 UTC).[2]
SVOM will study the explosions of massive stars by analysing the resulting gamma-ray bursts. The light-weight X-ray mirror for SVOM weighs just 1 kg (2.2 lb).[5] SVOM will add new capabilities to the work of finding gamma-ray bursts currently being done by the multinational satellite Swift Gamma-Ray Burst Mission.[5] Its anti-solar pointing strategy makes the Earth cross the field of view of its payload every orbit.[6]
