Video released today of the landing: https://twitter.com/NASAPersevere/status/1363929492138254340

What's it doing?
https://mars.nasa.gov/mars2020/timeline/surface-operations/
The surface operations phase is the time when the Perseverance rover conducts its scientific studies on Mars. After landing safely (Feb. 18, 2021), the rover has a primary mission span of at least one Martian year (687 Earth days).


finds rocks that formed in, or were altered by, environments that could have supported microbial life in Mars’ ancient past (Objective A)
finds rocks capable of preserving chemical traces of ancient life (biosignatures), if any existed (Objective B)
drills core samples from about 30 promising rock and “soil” (regolith) targets and caches them on the Martian surface (Objective C)
tests the ability to produce oxygen from the carbon-dioxide Martian atmosphere, in support of future human missions (Objective D)

This is awesome!!! I'm serious, I'm just amazed. I didn't think we'd have the bandwidth to send video like that from Mars. Just awesome

edit: I want to hear the microphone!!

edit 2: here's some audio from the microphone, just a bit of wind noise and the sound of the rover

Definitely recommend watching some of the stream today that had some commentary on the parachute opening, landing, etc particularly from about 16:00 to 25:00

the descent stage determines the actual landing position autonomously as far as I understand it so they didn't really have an exact location pre-programmed, but I heard scott manley mention it ended up ~5 meters from where it decided it wanted to go

That's pretty amazing.
During the live stream they showed the expected landing area deviation for each of the previous probes compared to this one and they were HUGE.

That landing zone accuracy is also incredibly important for the sample return mission. They'll need to land close to where those samples are cached, and being able to do that within a few km, or shoot... 1km to 500m away?
The little fetch rover will mostly likely be literally that, little, so it can't be running halfway across the planet to pick up samples.

As much as I wish humans can land on mars in my lifetime, I think I can probably count on seeing martian rock samples be returned to Earth which is... pretty incredible.

I cant even fathom the complexity of the sample return. Getting it there, getting it down to the planet, collecting the tubes then RELAUNCHING FROM MARS.

As far as the collection tubes:

quote:

Of the tubes aboard Perseverance, up to 38 are destined to be filled with Martian rock and regolith. The other five are "witness tubes" that have been loaded with materials geared to capture molecular and particulate contaminants. They'll be opened one at a time on Mars to witness the ambient environment primarily near sample collection sites, cataloging any Earthly impurities or contaminants from the spacecraft that may be present during sample collection.

The return missions:

https://www.nasa.gov/press-release/independent-review-indicates-nasa-prepared-for-mars-sample-return-campaign

Perseverance is part one of 3 of this plan. The other two:

quote:

an ESA-provided "fetch" rover to collect and deliver to a NASA-provided Mars Ascent Vehicle, which then would launch the samples into orbit around Mars. An ESA-provided Earth Return Orbiter would then rendezvous with the samples in orbit around Mars and take them in a highly secure containment capsule for return to Earth in the 2030s.

Infinitely many points, but zero length.


I went and looked at the picture on NASA's website which lets you zoom and and look around.

Around 1/3 of the way in from the left side, on the horizon, there's a patch of bright reflective material. Does that look like lander debris or maybe the heat shield to anyone else? I know there was a recent picture of Perserverance at its landing site with all of its lander pieces found around it.

here:


Edit so that I don't double post:

Also that patch of lighter sand near the rover--is that blown regolith from landing or has the rover already made its first test drive away from the landing site? I know they said it would just be a few meters.

Is there a plan for Percy to leave Jezero crater? I guess it's probably a lot of terrain for it to explore, but I'm looking at those walls and it doesn't seem like it'd be easy to get out.

I think the point where they wanted to land is suspected end of river delta, and they want to go uphill to delta itself, drilling samples along the way. I'm not sure it that is out of crater, but they at least want to climb something

I appreciate the tremendous, inspiring work that has been put into this project but it's always going to be a little bit of a letdown that we did all this work to put the robot on another planet and it hasn't yet discovered a single mysterious obelisk or orb.
