Satis (spacecraft)

Satis, also known as Asteroid Inspector, is a proposed planetary defense deep-space CubeSat mission under development by the European Space Agency (ESA) the Space Safety Programme. If approved, Satis will launch in 2030 to study an asteroid. Satis will be a 12-unit CubeSat based on a similar European mission M-ARGO.
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.
