Satis, also known as Asteroid Inspector,[1] is a proposed planetary defense deep-space CubeSat mission under development by the European Space Agency (ESA) the Space Safety Programme (S2P). If approved, Satis will launch in 2030 to study an asteroid.[2] Satis will be a 12-unit CubeSat based on a similar European mission M-ARGO.[3][4][5][6] As of February 2026, Satis was not mentioned in materials about future missions planned by S2P.[7]
Satis was also proposed as a mission to study the properties of the near-Earth asteroid Apophis before, during, and after its closest approach to Earth in April 2029. That would require launch in April 2028.[8][9]
