https://twitter.com/NASAPersevere 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)

Yeah, it's fantastic they had all the cams pointed at all the good poo poo. I'm looking forward to the future when we can watching in "real time" and not be limited by the 2mb upload speed on videos. How ever many decades that is away.

so much dust flying around... I wonder if it'll bring about any new conclusions as to the soil composition of mars just by man-made dust clouds

Has NASA said how accurate the landing was? I know they hit the lakebed, but how far from the exact target did they get?

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.

Mnoba posted:https://www.youtube.com/watch?v=3PrLXEbMgo4&ab_channel=VideoFromSpace 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. Cantorsdust fucked around with this message at 22:18 on Feb 24, 2021 |

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.

more falafel please posted: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 Mnoba posted:https://www.youtube.com/watch?v=3PrLXEbMgo4&ab_channel=VideoFromSpace It always amazes me when I see photos from Mars, Venus or Titan, that it looks like a pretty normal terrain
