    Me too, but like I said, it would work in this case: A lithobrake event would lithobreak the rover.

    It was intentional, meant as a small joke. I thought the parentheses, the use of both terms, quoting “lithobreak” and context would make that clear. Anyway, hopefully there will be no breaking.

    I remember being profoundly relieved when Curiosity made its safe landing in 2012 because it seemed at the time like a lunatic procedure full of potential failure points (not, mind you, that I know some superior way to land a very heavy but fairly delicate piece of equipment on Mars!). Hope all goes well with Perseverance as well. I see they keep upping the difficulty factor with each rover.

    Touchdown in Jezero Crater is expected at around 3:55 p.m. EST (12:55 p.m. PST).

    "Scientists look ahead to the search for past Martian life with Perseverance"

    https://spacenews.com/scientists-loo...-perseverance/

    On the eve of the landing of the rover Perseverance on Mars, scientists are looking ahead to the work it will do searching for evidence of past life on the planet and collecting samples for return to Earth.

    At a Feb. 17 briefing a little more than 24 hours before Mars 2020 arrives at Mars, project officials confirmed that the spacecraft is operating well and on course for a landing at 3:55 p.m. Feb. 18 at Jezero Crater.

    “Perseverance could land itself already without any more help from us on the ground,” Matt Wallace, deputy project manager, said at the briefing, based on its current status and the procedures on board to perform the various steps of entry, descent and landing (EDL). “So, the spacecraft is ready and, I think, the team is also ready.”

    Congrats to NASA and I am personally looking forward to Perseverance deploying its helicopter.

    I'll also add congratulations on a successful landing.

    I wonder if MRO got a photo of Perseverance parachuting down?

    Congrats! They are getting really good at this "land things on Mars" game. Experience and proper atmospheric modelling put to good use. Let's hope the new toys will be as stellar as the previous ones.
    With sufficient thrust, water towers fly just fine.

    They certainly tried. There was chatter in the control room abut MRO slewing to target Perseverance during EDL.No images released yet but it seemed like they were viewing MRO images in the control room.

    Looking ahead about 10 years, do they have a plan in place (yet) on how to bring back to Earth the drilled and stored core soil samples?

    Ask Elon Musk to do it!

    Nasa is planning a sample return in conjunction with ESA to be launched 2020-2030.

    Thanks bknight, that would be quite a feat, but I got faith in them. Amazing so far.

    And now an image from MRO's HIRISE camera which captured Perseverance while still on the parachute (similar to Curiosity's landing):

    MRO was launched 17 years ago. Quite an experienced workhorse!

    And has been in Mars orbit for just under 15 years. Another impressive NASA spacecraft.

    I’m very happy about this. I was concerned about the landing, especially since it was deliberately landing in rough terrain, with the new software and visual system hopefully acting as a capable pilot to land it in a safe spot. It seems to have worked.

    I’m really curious to see how the helicopter drone works out. No doubt they did extensive testing so I expect it will fly, but you never know for sure until it does.

    "NASA rover’s touchdown thrills Chinese netizens"

    https://www.globaltimes.cn/page/202102/1215960.shtml

    The successful touchdown, which was announced at mission control at NASA's Jet Propulsion Laboratory in Southern California around Beijing time 5 am on Friday, immediately thrilled Chinese social media users, with the topic rocketing atop of Sina Weibo search list, gathering over 30 million views as of press time.

    Chinese web users applauded the NASA craft's safe landing, and extended their sincere congratulations to the US.

    Commenting under a post featuring cheering NASA personnel during the landing, one netizen wrote that, "Although the US has been picking fights with our country during the past few years, we should not hold back anything but celebrate the rover's landing, as once it flies out of Earth, it represents the entirety of mankind. And our Tianwen-1 is coming next," collecting numerous thumb-ups.

    I’d seen this referred to as the “Armstrong maneuver”

    I may have missed it in the preceding pages but does anyone know the range of the drone/chopper? Sure hope it works ok as there are so many interesting places to explore from the air. Close up inspections of the ice caps, extinct volcanoes, collapsed lava tunnels, Valles Marineris, and dare I say, even the "pyramids".

    50 meters at an altitude of 3-5 meters, according to Wikipedia. Remember, this is an engineering testbed. The science will come in future missions. Here are 6 things to know, from NASA.

    And it's already been deployed and phoned home! Awesome!
