#GS-3 #Science & Technology #Space #Current Events #International

Key takeaways

  • Japan's JAXA launched the Martian Moons eXploration (MMX) mission using an H3 launch vehicle to collect surface samples from Mars's moon Phobos.
  • The mission carries a French-German rover named IDEFIX to navigate the low-gravity terrain of Phobos before returning regolith to Earth.
  • This mission represents the world's first planned sample-return effort targeting the Martian moon system.
  • India previously achieved historic space success in 2013 when ISRO's Mars Orbiter Mission (Mangalyaan) reached Mars orbit on its first attempt.

Why in News

  • The Japan Aerospace Exploration Agency (JAXA) launched the Martian Moons eXploration (MMX) mission.
  • The mission was launched using an H3 launch vehicle to investigate Mars's two moons, Phobos and Deimos.
  • It aims to bring physical samples collected from Phobos back to Earth.

Key Objectives and Features of MMX Mission

  • The primary objective of MMX is to study the origin, composition, gravity, internal structure, and surface features of Phobos while observing Deimos.
  • The spacecraft will collect regolith, loose dust, soil, and rock fragments from Phobos.
  • This endeavour marks the world's first sample-return mission attempt from the Martian system.
  • The mission carries IDEFIX, a small French-German rover designed to inspect the low-gravity surface and analyze terrain conditions for safe sampling.
  • MMX builds directly upon expertise gained from JAXA's previous Hayabusa and Hayabusa2 asteroid sample-return missions, utilizing advanced navigation, landing, and return-capsule capabilities.

Major Global Mars Missions

  • NASA's Viking 1 and Viking 2 landed on Mars in 1976, followed by Pathfinder deploying the Sojourner rover in 1997.
  • NASA's Curiosity and Perseverance rovers assess ancient habitability, while the Ingenuity helicopter achieved the first powered flight on another planet.
  • NASA orbiters like Mars Odyssey and the Mars Reconnaissance Orbiter (MRO) study surface geology and maintain communication links with surface landers.
  • China's CNSA executed the Tianwen-1 mission, deploying the Zhurong rover to explore Martian geology and potential subsurface water.
  • ISRO launched the Mars Orbiter Mission (Mangalyaan) in 2013, making India the first nation to reach Martian orbit on its maiden attempt.
  • The European Space Agency (ESA) operates Mars Express alongside the ExoMars Trace Gas Orbiter to examine surface structure and atmospheric composition.
  • The UAE Space Agency launched the Hope Probe in 2020 to analyze weather patterns and atmospheric dynamics on Mars.
