Ramses, orRapid Apophis Mission for Space Safety, is a proposedEuropean Space Agency (ESA) mission to anear-Earth asteroid99942 Apophis. If approved, it is expected to be launched in April 2028 and to arrive at Apophis in February 2029 before its closest approach to Earth. It will conduct multiple measurements of the asteroid's properties, to study possible response in case such an asteroid would be on a collision course with Earth.[1][2][3][clarification needed] Ramses mission will leverage much of the technology developed for theHera mission. At the asteroid, Ramses will deploy two smallerCubeSats.[4]

Timeline

[edit]
  • In July 2024, ESA’s Space Safety programme has received permission to begin preparatory work for Ramses.[5]
  • In October 2024, ESA signed a contract withOHB Italia SpA for preliminary work on the mission[6] and unveiled the official mission patch.[7] A funding decision is expected to be made in late 2025 at the ESA Ministerial Council.[8][9]
  • In March 2025, ESA has selected the first of twoCubeSats to fly onboard Ramses.[4]
