NASA Mars Ascent Vehicle Continues Progress Toward Mars Sample Return

NASA’s Mars Ascent Vehicle (MAV) recently reached some major milestones in support of the Mars Sample Return program. This video shows recent tests of the first and second stage solid rocket motors needed for the launch.
Mars Sample Return will bring scientifically selected samples to Earth for study using the most sophisticated instrumentation around the world. This strategic partnership with ESA (European Space Agency) features the first mission to return samples from another planet.
The two-stage MAV rocket is an important part of the joint plan between NASA and ESA to bring scientifically selected Martian samples to Earth in the early 2030s.

Horizontal SSTO is so ballsy!

[@grywacz]

Where did all that exhaust gas go.... in the vacuum chamber?

[@ssilent8202]

Andy Wier royalties for the name?

[@marcbonin1810]

Bravo oui.

Can I get that on the back of a prius?

[@victorrios8226]

It's a great success.... brilliant futuro for humanity and NASA 👏👏👏👏

[@CraigLYoung]

Somebody should check those bearings.

[@legomaster3189]

I agree why is it wobbly 😢

[@CarlosAlejandro.-ke6gr]

Question. Whats the solid propellant? Perchlorates are viable in mars? I guess not because of cracking risks due to cold temperatures

[@LukePrail]

Very stable, liquids can boil off unless you use hypergols. And even with a hypergolic engine, it still has a lot of valves. Solid motors are simply great for long term storage

I'm taking a musical I wrote about the space race to Broadway next year. Get ready people.

Can someone please explain why is the SRM2 spinning?

[@larsosborne8336]

The stage wil be spinning in flight.
High performance solid motors typically contain metals in the propellant mix.
When these are combined, it is possible for metal slag to build up on one side, causing it to become unbalanced and lose control.
While that might seem unlikely, it has happenned multiple times on other rockets, including one that had NASA satellites on it in 2015.

Why are you Americans not able to spell the word *CENTRE* , dammit!!!

[@terrafirma5327]

Solid test I would say, but its liquid fuel.

[@hamzahkhan8952]

it says it is solid fuel not liquid. solid fueled rocket motors are simpler and more powerful than liquid fueled engines, which make it a better choice for returning samples from mars.

@@hamzahkhan8952 interesting, thanks for the info. Rocketry isn't my specialty, by any means. I was just making a joke but I'm down for a learning opportunity

Hey NASA, do you think your "Astro-nots" visit the moon? LOL

hey you, do you think nasa really cares what you say in a youtube comment section? LOL
