Japan Embarks on Ambitious Mission to Retrieve Mars Moon Samples

What Happened

Japan has launched a historic mission to collect samples from Phobos, one of Mars' two moons, and return them to Earth by 2031. The mission, known as the Martian Moons Exploration Mission (MMX), is a five-year uncrewed endeavor led by the Japan Aerospace Exploration Agency (JAXA) with support from NASA. The MMX spacecraft will journey to Phobos, collect samples, and return to Earth, providing valuable information about the formation of the solar system and the origins of life.

The mission aims to answer questions about the origins of Phobos and Deimos, the two moons of Mars, which have puzzled astronomers since their discovery in 1877. The MMX spacecraft will first deposit a tiny rover called Idefix on the surface of Phobos to determine an optimum landing point for the larger lander. The lander will collect surface dust and dig into the surface to harvest samples, which will be returned to Earth for analysis.

What the Evidence Establishes

The MMX mission is an international endeavor that brings together expertise from Japan, the United States, Germany, and France. The mission's primary objective is to collect samples from Phobos and return them to Earth for analysis. The samples will provide valuable insights into the formation of the solar system and the origins of life. According to Kawakatsu Yasuhiro, project manager for the MMX, the Phobos mission will offer a glimpse into the origins of life and possibly pave the way for using Phobos as a base for a manned mission to the surface of Mars.

The MMX spacecraft will be equipped with an instrument called the Mars-moon Exploration with Gamma Ray and Neutrons (MEGANE) detector, developed by NASA's Jet Propulsion Laboratory (JPL) and Lawrence Livermore National Laboratory. The MEGANE system will help to determine the elemental composition of Phobos and provide clues about its origins. Dr. Abigail Fraeman of NASA's JPL noted that the spacecraft and rovers sent to Mars have collected information about Phobos and Deimos, but none of that data fits any hypothesis for the origin of the two moons perfectly.

Where the Accounts Conflict

There are different theories about the origins of Phobos and Deimos, and the MMX mission aims to provide answers to these questions. Some scientists believe that the two moons were formed from material that was blown into orbit by a massive impact on Mars, while others think they may be captured asteroids. The MEGANE system on the MMX spacecraft will help to determine the elemental composition of Phobos and provide clues about its origins. However, the mission's findings may not provide a definitive answer to the question of the moons' origins, and further research may be needed to fully understand the history of Phobos and Deimos.

The Russian space agency made four attempts to send probes to Phobos between 1988 and 2011, but only one of them, Phobos-2, made it to Martian orbit. The Phobos-2 mission suffered a catastrophic computer failure when it was close to touching down on the moon in March 1989. The MMX mission will face similar challenges, including the weak gravity of Phobos, which makes landing on the moon a formidable task.

Context and Stakes

The MMX mission is a significant undertaking that could provide valuable insights into the formation of the solar system and the origins of life. The mission's success could pave the way for future manned missions to Mars and the establishment of a permanent human presence on the Red Planet. The samples collected from Phobos could also provide clues about the potential for life on Mars and the origins of the solar system. According to David Lawrence, a planetary scientist at the Johns Hopkins Applied Physics Laboratory (APL), the MEGANE system could help to determine the elemental composition of Phobos and provide clues about its origins.

The MMX mission is also significant because it is an international collaboration between Japan, the United States, Germany, and France. The mission demonstrates the ability of nations to work together to achieve common goals in space exploration. The success of the MMX mission could also inspire future generations of scientists and engineers to pursue careers in space exploration and development.

What to Watch Next

The MMX spacecraft will take a year to reach Mars, orbit Phobos for about three years, make a close flyby of Deimos, and then take another year to bring its historic rock samples home. The mission's progress will be closely monitored by scientists and engineers around the world. The samples collected from Phobos will be analyzed using a variety of techniques, including spectroscopy and chromatography, to determine their composition and structure. The results of the analysis will be published in scientific journals and presented at conferences, providing valuable insights into the formation of the solar system and the origins of life.

The MMX mission is also significant because it is a precursor to future manned missions to Mars. The mission's success could pave the way for the establishment of a permanent human presence on the Red Planet, which could have significant implications for the future of space exploration and development. The mission's findings could also provide clues about the potential for life on Mars and the origins of the solar system, which could have significant implications for our understanding of the universe and our place in it.
