Mars Micro Orbiter

From Wikipedia, the free encyclopedia

Mars Micro Orbiter (MMO) is a spacecraft mission concept that would place a small and inexpensive satellite in orbit around the planet Mars to study some aspects of the Mars atmosphere in visible and infrared wavelengths.

The orbiter study will undergo a preliminary design review in March 2018, potentially launching as a secondary payload on another mission in 2020.

Overview[]

In April 2015, NASA's Small Innovative Missions for Planetary Exploration (SIMPLEx) program requested proposals for interplanetary CubeSat investigations, and received 22 submissions.[1] The MMO was not selected for launch, but in 2017 it was awarded grants[2][3] for further technology development.[1]

In 2015, the concept considered a 6U CubeSat with potential to also serve as an orbital communication relay for Mars surface-based missions,[4] and by 2017 it had evolved to a 12U CubeSat;[5] that is about 16 kg, and measuring 20×20×30 cm. The orbiter study will undergo a preliminary design review in March 2018,[5] potentially launching as a secondary payload on another mission[5] in 2020.[2]

The Principal Investigator is Michael Malin, from Malin Space Science Systems.[4][5]

Objectives[]

The MMO would study the Mars atmosphere in visible and infrared wavelengths from Mars orbit.[4] The science measurements include: [4]

  • atmospheric thermal structure, dust and condensate clouds, and seasonal and perennial polar cap behavior.
  • characterize the dynamics and energy budget of the current Mars atmosphere.
  • support present and future Mars missions.
  • help characterize present-day habitability.
  • potential to provide orbital communication relay for Mars surface-based missions.
