What's it Like Landing on Mars?

We Asked a NASA Technologist.

It's an intense, challenging and exciting  series of events.

NASA's most recent Mars rover, Perseverance, slowed from nearly 13,000  miles an hour to a soft landing on the surface in about seven minutes.

It involved a parachute, thrusters and even a sky crane.

But the majority of that deceleration was  caused by the Martian atmosphere creating drag on the rover's heat shield and that heat shield  went through a lot to keep the spacecraft safe.

Understanding what the heat shield experienced  during entry can help us design more efficient heat shields for future missions.

That's why  we installed MEDLI2, a set of temperature and pressure sensors spread across the inside of the  heat shield that measured the extreme conditions experienced during Perseverance's descent  to Mars.

With the data collected from MEDLI2, we'll be able to improve sizing predictions for  future heat shields and save spacecraft mass for scientific instruments, supplies and even humans.

So, what's it like landing on mars?
