NASA wants to literally throw it into the Martian atmosphere, which seems pretty cool tbqh
that defense contractor Lockheed Martin would be building the Mars Ascent Vehicle , the rocket that will someday take off from the surface of Mars to start the return journey with samples of the planet’s dirt, rocks, and atmosphere.The MAV will be a small rocket designed to get from the surface of Mars up into the planet’s orbit. In some ways, it will be just like any other rocket, explains Philip Franklin, NASA’s chief engineer on MAV.
Of course, the rocket has to get to Mars before it can take off from there. NASA will launch the MAV inside a larger spacecraft, which should take off from Earth around 2028. Since it’s being carried to Mars, the team is paying extra attention to keeping the vehicle small and light. “Mass is king,” Franklin says. The MAV will be somewhat diminutive.
After the lander navigates to a location in or near the Jezero crater, the lander and rocket will remain on Mars until it’s time to bring samples back. The MAV will be contained in a protective shell, which the engineers sometimes refer to as the igloo, Murrow says. The igloo helps keep the equipment warm in the harsh Martian conditions—even though the mission is timed for the relatively balmy Martian spring, temperatures will likely dip below -90F.
The rocket will remain horizontal during its stay on Mars, laying flat on the lander. In order to get the rocket into the air, the lander will loft it—basically, tossing it up into the air. Because the front will be tossed a bit harder than the back, the rocket should wind up pointing at an angle, towards the Martian sky. Then, in midair, the solid propellant will ignite, and the rocket will take off.
