“This artist's concept of JAXA's Martian Moons eXploration (MMX) mission shows the deployed spacecraft, Mars, and Mars's largest moon, Phobos, all together. MMX will orbit and survey Phobos from up close before deploying a rover to scout out the surface, and then land on it to collect samples and return them to Earth: the most ambitious sample return mission yet to be conducted in space exploration history.” (BigThink, MMX mission to reveal the origins of the Martian moons)
JAXA's mission to Mars is to bring 15 grams of Martian moon dust to Earth. This mission is the next step in Japanese space innovation. The last mission brought samples from asteroids. The new mission is more difficult. The 25 kg IDEFIX rover collects samples from Phobos. The new mission is called Mars Moons eXploration (MMX). The spacecraft uses multiple sensors. Researchers hope. That. They can solve the secrets of the carbon asteroid called Phobos. The thing. That makes Phobos and Deimos very interesting is this. They are carbon asteroids. Maybe. Mars captured those asteroids. Or, in some other models, a cosmic catastrophe separated them from Mars. In some models, Phobos is like a pile of gravel. In some other models, it’s like some diamond. A third model suggests that Phobos is sand. That ice binds together.
The MMX can answer that question. If Phobos is dense material, it could have formed when a cosmic catastrophe threw it away from Mars. The gravity could destroy the pile of gravel. MMX can also answer the question. Do those moons, Phobos and Deimos, have the same origin?
Their surface is covered by dust. That makes it hard to get data from their surface. That. Dark. Or brown dust is the reason. For. Why those moons are classified as “carbon asteroids”. The dust is similar to that that covers our Moon. But the main part of those moons' surface It is hidden under that dust.
“The relative sizes of the asteroid-like moons of Mars, Phobos and Deimos. Phobos is the innermost moon of Mars, while the smaller Deimos is more than twice as far away. Despite their appearances as looking similar to asteroids, it’s thought that Phobos and Deimos were once joined by a larger, third, inner moon, which has since decayed and fallen back to Mars. All are thought to originate from a giant, ancient impact.

“This artist’s concept shows Japan’s Mars Moons eXploration (MMX) spacecraft, carrying a NASA instrument to study the Martian moons Phobos and Deimos. The mission will contain a sample return component, and after collecting material from Phobos in 2027, it should return that component to Earth in the year 2031. We could know if Mars possessed ancient life, and if Phobos is made out of Martian material, just 5 years after the successful launch of MMX.”(BigThink, MMX mission to reveal the origins of the Martian moons)
The probe itself carries multiple very high-accuracy sensors. The list of those sensors is from the BigThink web magazine.
TENGOO is a high-resolution camera, resolving features as small as 40 centimetres (16 inches) on the surface, and can scout out a safe landing site.
OROCHI is a multiwavelength and wide-angle imager, perfect for identifying organic matter and water-rich material.
LIDAR is a laser altimeter that will measure altitude and reflectivity everywhere on the surface.
MIRS is an infrared spectrometer that will map out the distribution of any water-related substance over the entire surface.
MEGANE is a gamma-ray and neutron spectrometer that can map out the chemical elements composing the Martian moons.
CMDM is a dust monitor that can detect any dust rings around Mars, down to a minimum size of as little as 10 microns.
MSA is a mass spectrometer that will measure ions released by the moon itself, revealing the presence and cycles of ices.

“Rather than only the two Martian moons we see today, Phobos and Deimos, a collision followed by a circumplanetary disk may have given rise to three moons of Mars, where only two survive today. The idea is that Mars’s once-innermost moon was destroyed and fell back onto Mars long ago. This hypothetical transient moon of Mars, proposed in a 2016 paper, is now the leading idea in the formation of Mars’s moons, and helps explain the enormous differences in topography between Mars’s northern and southern hemispheres.

“This cute little guy is a model of the IDEFIX rover: a small rover designed to be landed on Phobos in advance of the main sample collection and return lander. The IDEFIX rover is 23 kilograms in mass, which would have the equivalent weight on Phobos of just 15 grams. By characterizing. the moon’s soil in advance and testing the ability to operate a wheeled vehicle on an ultra-low-density body, it will pave the way for the success of the sample return portion of the MMX mission.

“The Mars Orbiter Laser Altimeter (MOLA) instrument, part of Mars Global Surveyor, collected over 200 million laser altimeter measurements in constructing this topographic map of Mars. The Tharsis region (centre-left) is the highest elevation region on the planet, while the lowlands appear in blue. Note the much lower elevation of the northern hemisphere compared to the southern, with a mean difference in elevation of around ~5 km, thought to arise from the fallback of a third, large, former Martian moon.

“This close-up image of asteroid Itokawa was taken by the Hayabusa spacecraft in 2005 near its closest approach to the asteroid. Different parts of the asteroid have different densities, indicating that it formed as a contact binary from two predecessor “dirty snowball” asteroids. Itokawa likely has a history where several different smaller objects merged together to form what we see today: a common story among asteroid belt and Kuiper belt objects in our Solar System. Itokawa was the first object beyond Earth’s orbit to be successfully landed on, sampled, and to have its material returned to Earth.

The mission's purpose is to find out:
Was Mars ever home to life?
Was Phobos the result of a Martian impact or an asteroid capture event?
When will deposited Martian material display signs of being hydrated versus anhydrous?
(BigThink, MMX mission to reveal the origins of the Martian moons)
The problem is that the sensors must dig through the dust. Before. They can see Phobos’s surface. The probe uses a small rover to collect those samples. The probe drops that rover on Phobos. Before. It lands. The IDEFIX is the first rover to travel so far in the solar system.
The Big Think magazine describes IDEFIX like this:
And, in addition to all of those, IDEFIX is the small, mobile rover that will land on and explore the surface of Phobos before the main spacecraft lands to collect data and samples fit for the sample return component. There are three main drilling, sampling, collection, and return instruments:
CSMP, which will excavate the surface of Phobos to a depth of 2 cm (just under 1 inch), filling a core soil tube for the sample return capsule.
P-SMP, which will collect surface material pneumatically by injecting nitrogen gas on sub-second timescales.
And SRC, which is the sample return capsule that will store the samples collected by CSMP and P-SMP and return them to Earth’s surface.
(BigThink, MMX mission to reveal the origins of the Martian moons)
This kind of system requires highly advanced artificial intelligence and advanced mission planning. This sample-collecting system can collect data for new missions. Its purpose could be to return samples from Mars. Those samples can tell us whether Mars was once alive. And they can also answer questions. Why is Mars dry? Maybe. There was liquid water. Only for a short time. There is a possibility. That. Prokaryotic bacteria formed on that planet.
