RRM3

RRM3 [NASA]

RRM3 () is an ISS attached experiment to test refueling technologies in space..

RRM3 builds on the first two phases of International Space Station technology demonstrations that tested tools, technologies, and techniques to refuel and repair satellites in orbit. RRM3 will demonstrate innovative methods to store, transfer and freeze standard cryogenic fluid in space.

The mission is scheduled to launch to the space station in 2018. It has a projected two-year life on station, though NASA intends to accomplish RRM3's objectives within the first year. RRM3 is developed and operated by the Satellite Servicing Projects Division at NASA's Goddard Space Flight Center in Greenbelt, Maryland, under direction of NASA's Space Technology Mission Directorate.

The RRM3 Primary Objectives are:

  • Perform cryogenic liquid methane transfer in micro-gravity
  • Maintain cryogen fluid mass for six months via zero boil-off

The RRM3 Secondary Objectivesare:

  • Demonstrate and validate the Compact Thermal Imager - An instrument that utilizes available room on RRM3 to observe Earth to detect smoke and fires, as well as measure crop transevaporation.
  • Complete Machine Vision Tasks - In-space assessment of fiducials (decals) with unique patterns that enhance machine vision algorithms and aid in autonomous rendezvous and tool positioning.

RRM3 consists of following systems:

  • Fluid transfer system (including tanks and lines)
  • Cryogenic fluid (liquid methane)
  • Cryogen interface (cooperative and non-cooperative)
  • Compact Thermal Imager (CTI)
  • Innovative vision systems
  • Cryocoolers
  • Tools and adapters
    • Multi-Function Tool 2 (MFT2)
    • ryogen Coupler Adapter (CCA)
    • Cryogen Servicing Tool (CST)
    • Visual Inspection Poseable Invertebrate Robot 2 (VIPIR2)

RRM3 was launched with Dragon CRS-16 towards the ISS, where it will be installed on ELC 1
