The New Phobos Martian Moon Rover That Weighs In At Solely 15 Grams

Although for a lot of many years the planet Mars has been prodded, poked, pushed upon, flown over and particularly orbited by varied spacecraft, landers and rovers despatched over by a sure humanoid species on Earth, the 2 moons that orbit Mars have featured considerably extra in science-fiction and video video games than in scientific literature. This is now about to alter when the Martian Moons eXploration (MMX) mission launches on October nineteenth, which is able to embrace a pattern return from Phobos.

So far these two moons of Mars – Phobos and Deimos – have solely obtained just a few cursory glances by passing spacecraft, leaving many elementary questions surrounding their formation and composition very a lot open. With the MMX mission this could change dramatically, with this spacecraft meant to carry out detailed measurements of each moons.

In addition a rover – referred to as Idefix – will carry out a touchdown on Phobos for observations of its floor. This can be fairly a feat as regardless of this lander coming in at 25 kg, on Phobos’ floor it is going to weigh solely 15 grams because of the low gravity, and even lower than the diminutive canine companion of Obelix, with potential bouncing as we now have seen with earlier touchdown makes an attempt on such small our bodies.

After launch, the MMX mission will take a year to arrive at Mars, in August of 2027, with Idefix being launched in early 2029 for its hopefully delicate paws-down on the floor of Phobos the place it could possibly scurry about for some time till the primary MMX spacecraft lands later for its pattern retrieval and return a part of the mission. If every part goes nicely, this may imply {that a} pattern of Phobos needs to be touchdown in Australia in 2031.
