How NASA Plans To Get Astronauts Back From Mars!

When NASA engineers look at Mars, they see a planet-sized Venus flytrap.
It lures us in with the promise of scientific discovery—but the moment we land there, gravity and a harsh climate will conspire to keep us stuck on the surface.
And that’s not an option. If The Martian holds one lesson for real-life space exploration, it's that the public won't stand for spending billions of dollars only to leave astronauts stranded on another world. The most crucial part of any NASA plan for visiting the red planet, arguably, is getting off of it.
The spacecraft that NASA would build to get the job done, the Mars Ascent Vehicle (MAV), represents a formidable engineering challenge. When fully loaded with fuel, it’s too heavy to launch from Earth and land safely on Mars.
Instead, the vehicle would need to be pre-assembled and sent to the red planet—years before the astronauts arrive—where it would make its own propellant by squeezing it out of the thin Martian atmosphere.
And after that? The MAV must be built tough enough to remain fully operational despite being pummeled by massive dust storms and punishing UV radiation. When the cramped vehicle does finally take off, it needs to sustain the astronauts for days, as they maneuver to rendezvous with the orbiting vessel that will finally take them home.
The Mars Ascent Vehicle will be a mission within a mission: a crewed spacecraft launched into orbit from the surface of an alien planet.
And there’s only one chance to get it right.
So yes, we do know how to get to Mars. We even know how to land on Mars.
All that remains is hard part: figuring out how to leave.
In today’s episode of Great SpaceX, we’re taking a quick look at how NASA plans to get astronauts back, from the red soil of Mars, home.
