Exploring Mars is not just a part of movies like The Martian, it happens quite constantly by NASA. NASA has recently declared the finding of an extraordinarily different rather metallic meteorite on the surface of the red planet. Of course, this is not the first meteorite that has hit the surface of Mars. But it’s structure and material makes it unique. NASA’s scientists have named it ‘Egg Rock’ meteorite.
The image was first taken by Curiosity Rover, while roaming around Mars’ Mount Sharp, on 27 Oct, 2016. The shocked scientists from Mars Science Laboratory (MSL) decided to explore this weird-looking rock’s chemical composition deeply, by using ChemCam to take some closer images of it.
The closer images have shown it as a strange looking, ovoid shaped iron-nickel meteorite. The Egg Rock meteorite on Mars has a fallen on it from the Martian sky. Quite strangely, it has a smooth and lustrous surface. The deep grooves on the surface suggest that this piece have been through some severe melting process.
Now that is quite unlike the other meteorites that normally hit Mars. Normally, we find only the red-orange rocks on it’s surface. The red planet has a very thin atmospheric layer and the asteroid belt is situated quite close to it. That’s why finding meteorites here is not a big deal.
This is the first Egg Rock meteorite on Mars but not on earth. Our earth has several times been hit by iron-nickel meteorites. Let’s see what a member of Chemcam team member has to say about them, “Iron meteorites provide records of many different asteroids that broke up, with fragments of their cores ending up on Earth and on Mars…Mars may have sampled a different population of asteroids than Earth has.”
Egg Rock Meteorite on Mars can be named as one of the biggest discoveries by Curiosity Rover. But its journey is still going, to know more about the surface of the planet and any possible signs of life somewhere in the past.
