    Nasa should send a DJI Chines drone to Mars, cost only $1000. https://kolarivision.com/wp-content/uploads/2018/09/mavic-2-pro.jpg

    The drone under discussion here isn't designed for Mars. And no drone
    designed to fly in Earth's atmosphere would fly on Mars in any case.
    (And I'm wondering where you'd charge it after its few flying minutes
    are used up.)

    Despite the -200C temps, it might be easier in a way to fly on Titan than Mars because it has a dense atmosphere. Will be very interesting to see how they configure the motors to operate in those conditions.

    Interesting design problems. I have to be careful using my tractor
    when it gets down below -20C or so, because metal becomes brittle and
    can fail easily. It's a big problem with equipment at the Antarctic
    bases. There has to be some serious materials engineering to deal with
    these truly extreme lows.

    I was just recently reading an article about how someone had designed the "toughest metal ever", an alloy of chromium, cobalt, and nickel.

    https://www.livescience.com/toughest-material-nickel-cobalt-chromium-alloy

    I was rather surprised that it was claimed that cobalt and nickel were "prohibitively expensive". Costing about twice as much as the other metal, chromium, I had not thought they were too bad for the applications that need such an alloy as this.

    As this alloy retains its toughness down to -196 Celsius, it would seem that demanding cryogenic applications would seize on this alloy quickly. But perhaps there are cheap iron alloys out there with which it is possible to manage.

    And silver is cheaper than printer ink, despite the fact you have to mine and process a lot of rock to get it. Pricing is suspect for a number of things on this planet.

    There is a lot of clever chemistry in printer inks and toners - although
    the main reason they are so expensive is that the price of the printer
    hardware is massively subsidised by the expectation of selling you ink!

    I try to find printers where the OEM cartridge lockin has been defeated
    by third party ink cloners so that I pay £20-40 for a set of toner
    instead of £200-300 for the OEM version.

    Maybe, other materials
    can be used for bearings and moving parts.
    Jet plane's engines, are mostly titanium!
    There are also various Titanium alloys.
    As a machinist at Aerospace co. had my share working with Titanium.
    Bitch material to machine.
    It has a narrow range of cutting speeds and feeds to use, or destroys the cutting tool's edge or even burns it out!
    superalloys
    The low-pressure compressor blades and several high-pressure compressor blades are made of Ti-6Al-4V alloys which are also used for the fan blade, and the rest of high-pressure compressor blades are made of Ni-based superalloys such as Hastelloy X.<<
    Oh, yes!
    The Hastelloy X.
    If I want to die early, machine this sucker.
