Robotic Refueling Mission 3 (RRM3)

Mission Facts

  • Launch date: 5 Dec 2018
  • Launch vehicle: SpaceX Falcon 9
  • Mission type: ISS flight experiment
  • Destination: ISS
  • Quest Application: IMLI, insulating Flight Receiver Tank
  • Primary mission objectives:
    • Demonstrate in-space cryogenic propellant transfer
    • Achieve Zero Boil Off of the cryopropellant


With the RRM3 spaceflight Integrated MLI (IMLI) reached TRL-9. Quest collaborated with NASA’s Goddard Space Flight Center to design, analyze, and instrument an insulation solution for the Flight Receiver Tank. RRM3 was the first successful in-space cryogenic propellant transfer. Underscoring the predictability of IMLI, heat flux was modeled as 0.517W, actual measured was 0.515W.
