description MMX (Martian Moons eXploration) Overview
The Martian Moons eXploration (MMX) is a robotic space mission currently in development by the Japan Aerospace Exploration Agency (JAXA). The mission is designed to survey Mars's two moons, Phobos and Deimos, and to collect and return a surface sample from Phobos to Earth. By analyzing these samples, scientists aim to determine the origins and evolutionary history of the Martian satellites.
help MMX (Martian Moons eXploration) FAQ
What is JAXA's MMX mission designed to do?
MMX, or Martian Moons eXploration, is a robotic mission designed to study both Phobos and Deimos. Its central objective is to collect a surface sample from Phobos and return it to Earth.
Why is MMX targeting Phobos instead of landing on Mars?
Phobos may preserve material connected to the early history of the Mars system, including clues about whether it formed from Mars or was captured. Returning a sample gives scientists material that can be studied in Earth laboratories.
Will MMX study Deimos as well as Phobos?
Yes, the mission is planned to observe both Martian moons, although the landing and sample-return operation is focused on Phobos. Comparing the two moons may help explain their different origins and surface histories.
Which agency is leading the MMX mission?
The mission is being developed by the Japan Aerospace Exploration Agency, JAXA. International partners including NASA, CNES, and Germany's DLR are contributing instruments or mission hardware.
