The Martian Moons eXploration (MMX) rover is a rover set for launch in 2024, it is part of the Martian Moons eXploration (MMX) mission.

Overview[edit]

The rover will land on Mars's moon Phobos before the main spacecraft (see Martian Moons eXploration (MMX)) during one its rehearsal landings. Landing and deployment will be a crucial phase, in which the rover will need to 'stand up' to its nominal operation stance.[4] After succesful deployment, the rover will explore the surface of Phobos and assist the MMX spacecraft in its landing. This rover will be the first in a microgravity environment.

International collaboration[edit]

CNES and DLR are the main contributors to the mission, each party responsible for different parts of the rover.[5]

CNES is responsible for:

  • Structure and thermal
  • Solar array
  • Service Module
  • On-board computer (OBC)
  • Power control and distribution unit (PCDU) and battery
  • RF box and Antenna
  • WheelCams
  • NavCams

DLR is responsible for:

  • Locomotion
  • Chassis
  • Payload and locomotion electronics box
  • Shutters
  • miniRAD
  • MECSS
  • RAX

Scientific payload[edit]

The scientific payload of several contributions:[1]

  • NavCams - Navigational Cameras, provide insight into regolith behaviour and makes images of the Phobian landscape. Also used for localisation and context for other instruments.
  • WheelCams - Wheel Cameras, observe the wheels, allows for characterisation of regolith particle properties and size distribution.
  • RAX - Raman Spectrometer, studies surface mineralogy.
  • miniRAD - Mini RADiometer, studies surface temperatures and thermo-physical properties.
  • GRAMM - Ground penetrating rader, to study physical structure of the subsurface.
  • GRASS - Gravimeter, measures local gravity to characterise temporal and spatial variations.
