From July to September 2023, an initial function test of the solar array panel (SAP) that will be installed on the Martian Moons eXploration (MMX) spacecraft was conducted at Mitsubishi Electric Kamakura Works.
On August 10, 2023, the Johns Hopkins University (JHU) Applied Physics Laboratory (APL) conducted a Pre-Shipment Review (PSR) for MEGANE, one of the observation instruments onboard the Martian Moons eXploration (MMX) spacecraft.
The Emirates Hope Mars Mission has captured spectacular images of Mars's outer moon, Deimos. But what does this tell us about the history of the two moons?
10 scientists from across the United States were selected in April 2023 by NASA to join the international science team for the Martian Moons eXploration (MMX) mission. The researchers will join the Japan team in analysing data from the spacecraft’s onboard suite of instrument as MMX takes a close look at Phobos, Deimos, and the Martian environment from orbit, as well as participate in the investigation of the sample MMX will collect from Phobos and return to Earth.
In December 2022, members of the Martian Moons eXploration (MMX) mission and the Twinkle Space Telescope held a joint strategy meeting to help ensure the successful collection of a sample from the Martian Moon, Phobos, by the MMX spacecraft.
“The mission is to collect a sample of at least 10 grams of sample from a depth of more than 2 cm within 90 minutes after landing on the Martian moon Phobos.” Dr Hiroki Kato of JAXA started working on the development of a sampling device around 2015 to meet this difficult task. He is now focusing hard in order to "make this happen" in preparation the launch in FY2024. In this interview, Kato tells us why it is necessary to collect samples in 90 minutes, what kind of methods are used for sample collection, the difficulties that exist, and the kind of future is in sight.
Preparations have already begun for receiving the sample from Phobos that will be returned by MMX. We talk with Tomohiro Usui, lead of the Japanese curation team, about the preparations for the most precious of deliveries.
One of the main hypotheses for the formation of the moons of Mars is that the moons are captured small bodies, due to their resemblance to the D-type asteroids. But what are D-type asteroids and what would be the scientific importance of the MMX mission returning a sample from this asteroid class?
“With MMX, we will study a tiny moon,” says Hyodo. “But this is not only about the moon, it is also about Solar System material and material from Mars.” Dr Ryuki Hyodo shares the science behind JAXA’s upcoming MMX mission to the Martian moons, and the unique features of this journey to Mars’s domain.
A JAXA integrated PDR that considered all elements was conducted in February 2021. A large number of participants from inside and outside of JAXA were involved in the judging, and the transition to the next phase (Critical Design Phase) was approved.
