back to article And it's off! NASA launches nuke-powered, laser-shooting, tank Perseverance to Mars to search for signs of life

Perseverance, the heaviest and most complex Martian rover yet, is on its way to the Red Planet aboard an Atlas V rocket that blasted off from Cape Canaveral, Florida, on Thursday. NASA had a small launch window until the end of August to send the nuclear-powered bot off into space before Earth started moving away from Mars in …

    RIMFAX

    First up, +1 to everyone involved in this - it's awesome!

    However, regarding "RIMFAX", I guess we have to accept some bits of tech have to be developed years in advance and may actually be a bit out of date by the time they are used; I'm sure I'm not alone in hoping for something a bit better than faxed copies of crater rims... ;-)

        You think only Brits have seen Red Dwarf? That'd be incorrect. In fact, I'll bet you a plugged nickle that more Yanks have watched it than Brits.

        "This will only work for Brits"

        Au contraire, I live in the city where PBS (the Public Broadcast System) first introduced British Comedy in the form of Monty Python's Flying Circus to the US in the mid 70's. Since that time I have watched so many Britcoms on PBS, including Red Dwarf, that I have trouble remembering them all but here is a list of the ones I remember, some better than others:

        Monty Python's Flying Circus, The Two Ronnies, Butterflies, Are You Being Served, Red Dwarf, Black Adder, To The Manor Born, Benny Hill, Ripping Yarns, The Good Life/Good Neighbors, Open All Hours, Only Fools and Horses, Mr Bean, The Young Ones, My Hero, Absolutely Fabulous, Yes Minister/Prime Minister, 'Allo'Allo!, Chef!, The Fall and Rise of Reginald Perrin, Fawlty Towers, French and Saunders, Goodnight Sweetheart, The Hitchhikers Guide to the Galaxy, Jeeves and Wooster, Keeping Up Appearances, Up Pompeii!, Waiting for God, The Vicar of Dibley

        I'm sure they didn't show all episodes from all the years that some of these shows ran but at least I got a good sampling of them. I stopped supporting and watching PBS many years ago after they started airing commercials, and pretty much all TV shortly after that so I don't know about any of the more recent ones that they might have aired. Judging by my previous experiences with Britcom, I'm sure there are more than a few I wish I did know about.

        P.S. I am currently designing a talking toaster with on the edge AI. Any suggestions?

                I'm sure that those people who say "yar" and hang out in a bay would be happy to share a good quality copy. Hypothetically speaking. And then once you know it's worth the money (it totally is) you can order the DVDs. If DVDs are still a thing.

                Personally I'd rate Black Books as a "make the time: take a day off work" level priority. But to each his own. ;)

                  Yes, DVDs are still a thing. But. There's a always a "but". But, if it's not currently available on amazon.com, you might as well forget about it. Friends in the USA tell me ordering DVDs from amazon.co.uk is currently not viable. Some orders have taken months to arrive, others are now no longer available to order from the UK to USA and those which are still available have prohibitive shipping charges. If the US ever gets COVID-19 under control and flights resume between the UK and USA, orders may return to a semblance of normality but for the time being, assume that non-essentials are not going on cargo aircraft (a lot of cargo normally goes on passenger aircraft too, and they ain't flying)

      Re: RIMFAX

      RIM is from rime, meaning frost. FAX is from an Old Norse word meaning mane (as in horse). The rover is named after one of the horses in Norse mythology, Hrímfaxi ... Thus William Morris' Silverfax (from The Well at the World's End), which in turn brought us Tolkien's Shadowfax.

      Back in March '94, when we were inspecting The Dish at Stanford after an accident sent it nose-first into the ground, one wag commented that ground-penetrating radar would have to be a lot smaller in order to become useful technology ... I guess he was right. Now it's small enough to send to Mars.

      It's all very well. But who's going to explain it to Martian police when they have to shut down the local airport - due to unauthorised drone flying within its perimeter?

        Re: Roll on the test flight....

        So, they're sending a mini-nuke to Mars, and you're more worried about the drone shutting down the local airspace?

        I'd be more worried about it fireballing into a previously unknown city and frying all the inhabitants.

    hopeful, but nervous

    I'm hopeful and excited for the mission, but nervous about the landing.

    7 minutes of terror sounds about right. Lots of complexity, lots of things that can go wrong, lots of automation (pros and cons to automation, of course). I'm thinking there will be a lot of blue faces at mission control during the landing sequence. Wishing craft and designers the best of luck!

    1. Tessier-Ashpool

      Re: hopeful, but nervous

      Should be ok. Retro rockets are tried and trusted technology, critical to every soft landing of astronauts returning to Earth on Soyuz capsules.

      I’m looking forward to the day when we get to see real video of it happening rather than CGI. Surely that’s worth the few million dollars it would take to do that.

    Well, I am glad that they were able to launch the mission during the current launch window

    And I am sure that H.G. Wells is having a chuckle somewhere about mankind sending yet another heat-ray bearing mechanical invader to Mars!

    So, let's hope that NASA is able to land the rover in one piece and get some more great science out of it. However, their track record for successful Mars missions has been pretty good now that they have figured out the whole metric/English measurement system conundrum and successfully used the "Seven minutes of terror" landing system already.

      Whatever the length, I hope for a safe landing in February=.

        Decimal minutes? Next you'll be proposing ten months: five with 36 days and five with 37 days. Or maybe all with 36 days and five days of holiday at the end of the year.

    Longevity

    A very hand-wavey argument:

    If you want to be 95% sure that all of your rover's modules are still working after 90 days, you need to ensure that each one has a 99% chance of still working after 90 days. And if that's the case then there's a 66% chance that a component will be working after ten years.

    Which is more or less what we saw - some bits stopped working.
