The longstanding mystery of Mars' moons—and the mission that could solve it
Credit score: NASA

The 2 small moons of Mars, Phobos (about 22km in diameter) and Deimos (about 13km in diameter), have been puzzling scientists for many years, with their origin remaining a matter of debate. Some have proposed that they could be made up of residual particles produced from a planet or giant asteroid smashing into the floor of Mars (#TeamImpact).

An opposing speculation (#TeamCapture), nonetheless, suggests the moons are asteroids that were captured by Mars’s gravitational pull and had been trapped in orbit.

To resolve the thriller, we’ll want materials from the moons’ surfaces for analytical analyses on Earth. Fortunately, the Japan Aerospace Exploration Company (Jaxa) will launch a mission, named “Martian Moon eXploration” (MMX), to Phobos and Deimos in September 2024. The mission might be carried by a newly designed rocket, the H-3, which continues to be beneath improvement.

The spacecraft is predicted to succeed in Martian orbit in 2025, after which it is going to orbit Phobos and at last acquire materials from its floor earlier than returning to Earth by 2029.

It will make it the following in a collection of current missions bringing materials from area again to Earth, following on from Jaxa’s profitable mission to asteroid Ryugu (Hayabusa2), in addition to Nasa’s Osiris-Rex mission to asteroid Bennu and the Chinese language House Company’s Chang’e 5 mission to the Moon.

Giveaways

If an impression origin did certainly happen, we might anticipate finding comparable materials on Phobos to that which is discovered on Mars. Whereas we do not need any materials returned straight from Mars (but), we’re fortunate sufficient to have rock that has been ejected off its floor which ultimately discovered its solution to Earth.

These meteorites might subsequently be just like the fabric returned from Phobos, offering a unbelievable comparability.

Within the case of a captured asteroid origin, nonetheless, we usually tend to discover materials on Phobos that’s discovered on different asteroids in our photo voltaic system. The prevailing speculation within the #TeamCapture group is that the moons are made up of the identical rock as meteorites, referred to as carbonaceous chondrite. Fortunately, we have now loads of such meteorites and samples that we might examine with the Phobos materials.

Evaluating meteorites and materials introduced again from Phobos might be a unbelievable device for serving to us perceive the origin of the 2 moons. As soon as we have now materials within the laboratory, rigorous analytical strategies will be utilized to the samples.

One such approach is oxygen isotope evaluation. Isotopes are variations of components whose nuclei have extra or fewer particles referred to as neutrons. Oxygen, for instance, has three steady isotopes, with atomic lots of 16, 17 and 18.

The sum of the isotopic ratios of oxygen-17/oxygen-16 and oxygen-18/oxygen-16 is denoted as Δ17O, and is attribute of particular father or mother objects. Relying on the place within the photo voltaic system a rocky physique is shaped, a definite oxygen composition is acquired and retained within the rocks. For instance, rocks from Earth have Δ17O of round 0, whereas meteorites from Mars have Δ17O of round ~0.3. Subsequently, rocks from Earth and Martian meteorites can be readily separated from each other.

If Phobos shaped in the identical or not less than comparable location within the photo voltaic system to Mars, we might anticipate the composition of the fabric introduced again by MMX additionally to have Δ17O of round 0.3.

As talked about beforehand, #TeamCapture recommend a carbonaceous chondrite-like origin for Phobos. All recognized carbonaceous chondrites studied by scientists have revealed unfavorable isotopic Δ17O, starting from -0.5 all the best way all the way down to -4. Oxygen can subsequently be an especially highly effective device in deciphering the origin of the moons of Mars, and needs to be a excessive precedence for the mission as soon as materials is returned to Earth.

If Phobos does certainly symbolize an historical fragment of Mars, it might comprise probably the most primitive of Martian materials. Mars has skilled a variety of processes which have altered the rocks on its floor, together with wind erosion and water alteration. Primarily based on options comparable to dry river beds noticed from orbiters comparable to Viking, it’s clear that water on Mars as soon as existed.

This water seemingly originated from a mixture of asteroids and comets, and volcanic exercise. Mars additionally retained a thick environment, which allowed water to be current as a liquid on the planet’s floor.

Phobos, alternatively, has remained an airless physique the place processes comparable to contamination from water haven’t occurred (although minor impression occasions might have taken place). Which means samples returned from Phobos might present extraordinarily necessary insights into the unique water content material of Mars, and a window to processes that occurred within the early photo voltaic system.

MMX is without doubt one of the most fun deliberate missions in area exploration. With lower than a yr to go, our fingers are already firmly crossed for a profitable launch, pattern acquisition, and pattern return. Many scientists together with myself would completely love the potential for someday finding out these samples.
