First Flight on Another Planet!

  • The Mars Helicopter aims to make the first powered flight on another planet when it takes off on Mars as part of the Mars 2020 mission. I learned a lot getting to visit the drone right before it was mounted on the rover.
    How do you fly in 1% of Earth's atmosphere:
    Have large rotors (they are 1.2m in diameter) and spin them very fast, around 2500 RPM (5x the speed of a helicopter on Earth).
    Plus the aircraft has to be light:
    The Mars helicopter weighs in at 1.8kg or around the same as a laptop. Every piece had to be stripped down for weight. Instead of using aerogel for insulation, the craft makes use of CO2 gaps between components. Even aerogel was too heavy!
    One of the major challenges is surviving the Martian night:
    Temperatures plunge to -80C to -100C so two thirds of the craft's power is actually used to keep its electronics warm. Only one third is used for flying. The estimated flight time is 90 seconds.
    The craft can't be driven remotely, it will have to fly autonomously, using its own sensor suite to determine how to fly. The round trip 20 minute delay with Earth means steering the craft from mission control would be impossible.

    The martian soil is about 15% iron.
    Imagine the amount of iron those magnets in those electronic drone would collect around them props.

    why don't they just use atomic batteries in the drone o.o' i mean its not like its gonna be around humans on mars o.o' probably wont ever have to recharge the thing in its lifetime

    I would like to know why didn’t they choose a fixed wing drone instead of the rotating wing model. It looks like it would have quite more flight time, plus they could use solar panels on the huge wings, providing power during the flight. I know there are no runways on mars, but there are solutions to that.

    So I am sure this has been studied and all difficulties answered. Yet I ask:
    -when the Helicopter lands, creating dust, how is dust going to be kept off the PVP?
    -will the weight of sand disturb flight charasteristics?
    -will sand at take off and landing not sand through those blades, as they are spinning at 23'000 - 29'000 rpm?
    -are all the sensors (i.e. Gyroscope) calibrated to the Mars Atmosphere?
    -will UV radiation have an effect on the carbon fiber blades?
    -why did you not send 2, incase one fails?

    Why wouldn't they use a nuclear thermal generator as the power source?
    Keeps itself worm, could fly for years, send a signal to Earth, could fly at night, could fly on the poles, craters, canyons, with aerial photography it could technically give us a google street view of the planet... Nop batteries.

      If you design it as a VTOL, and have like 90+% of it be airfoil surface, sure.
      How are you going to get a VTOL flying wing, though, is the question.. and it would need to fly at close to or greater than mach 0.7 on mars, have its own lightweight fuel, essentially you are thinking of making a gliding rocket.

      Now a high speed rail system would be much more suited for Mars as Lord Elon won't have to worry about pumping down a massive tube there!

    I’m just here to contest your “highest a plane has ever flown” comment of 85k ft in the SR71. By multiple definitions this is wrong. Several jet aircraft have made it over 100k ft.. F15 up to 103k ft, Mig 25 up to 123k ft. Don’t even @ me with ceiling definitions. “Plane has ever flown” does not mean “plane has ever been capable of cruising at”.

      there is a LOT of room for improvement when it comes to batteries. and batteries that can take the temperature swings of mars. you should research that and improve upon power density!
      The little copter might be restricted by the lighter weight single crystal silicon solar panels, too. not the most efficient variety out there, but priority is light weight if you can't even use aerogel.

    14:17 .. mate.. the purpose of this mission is to create a level of propaganda sufficient to get these pseudo scientific grant grabbing jokers playing 2.5x speed video at retards faking terminology to sound "speshul" to get themselves into the news.. from a helicopter perspective there is (effectively) NO atmosphere on mars.. you are dealing with 1/3rd the gravity but about 1/300th the atoms.. which means you're displacing the mass of the helicopter by shoving away.. nothing.. the only way you'd even have a chance is an ultra light arrangement using huge wings.. watching them use earth based rotors made me cringe.. almost as much as listening to her describe how a gyro they bought off ebay worked.. pretty much listening to her talk about the principle of captured Co2 (which is simply the principle behind your "loft insulation") - like she is some sort of Jedi is just a joke.. I can't cope with this crap honestly..

    That bit about the blades reaching the speed of sound deserves a bit more words to it, because _of course_ it has been made, and damn was it crazy thing.
    From the XF-84H wiki ; "The XF-84H was almost certainly the loudest aircraft ever built, earning the nickname "Thunderscreech" as well as the "Mighty Ear Banger". On the ground "run ups", the prototypes could reportedly be heard 25 miles (40 km) away. Unlike standard propellers that turn at subsonic speeds, the outer 24-30 inches (61-76 cm) of the blades on the XF-84H's propeller traveled faster than the speed of sound even at idle thrust, producing a continuous visible sonic boom that radiated laterally from the propellers for hundreds of yards. The shock wave was actually powerful enough to knock a man down; an unfortunate crew chief who was inside a nearby C-47 was severely incapacitated during a 30-minute ground run. Coupled with the already considerable noise from the subsonic aspect of the propeller and the T40's dual turbine sections, the aircraft was notorious for inducing severe nausea and headaches among ground crews. In one report, a Republic engineer suffered a seizure after close range exposure to the shock waves emanating from a powered-up XF-84H."
    Lin Hendrix, one of the Republic test pilots assigned to the program, flew the aircraft once and refused to ever fly it again - he told the formidable Republic project engineer, "You aren't big enough and there aren't enough of you to get me in that thing again".

    Who gives a flying fart about a few snaps from Mars except for the thousands of exorbitantly-compensated engineers who make a handsome living from them. There is nothing on ANY other planet that we can't find here on earth. All the planets consist of the same elements. It would be ridiculous to mine anything on another planet since it costs billions to ferry it back to the earth. Space Exploration is just a meaningless hobby, nothing more. Of course it costs taxpayers hundreds and hundreds of billions of dollars for absolutely no worthwhile purpose.

    So what do they do when it fall over on Mars? How do they correct it? It's a pretty common issue that drone hobbyists deal with.

  • redstone craft guy

    3:46 yes and no. Yes, single rotor is more efficient. No, it's not more efficient because of it coaxial propeller configuration. Coaxial propeller configuration is actually less efficient than just using one rotor m.usclip.net/video/tFJyE3Uns3o/video.html
    The reason why they went with the coaxial configuration is to cancel out the reaction torque create by the other one.

    Nice video thanks.
    I'm wondering how ''aircraft'' designs would be in order to allow a lift of the aircraft in such low atmosphere density? I can only guess that our actual aircrafts would not even takeoff because of the wing design and mostly weight.

      @Riccardo Orlando Me too if we speak fluids dynamics on other worlds. Though I worked in Aerospace for almost 10 years but that doesn't make me skilled enough to know which concept would be necessary to fly on Mars but that would be interesting to see one.

    • Riccardo Orlando

      Our aircraft would definitely not work. I expect to make a plane work, you'd need massively oversized and aggressively pitched wings. I know very little of fluid dynamics, though.

    For those who think he could get into Area 51, and that there may be some 'crazy tech that could end the world' and 'aliens' hidden there, here's your beliefs disproved.
    Firstly, Area 51 is a Black-World USAF Facility. Black-World Facilities have the highest levels of secrecy and defense, so anyone who is unauthorised to enter is basically dead. Straight away. Shoot first, ask questions later. Secondly, if he applied to get into Area 51, he'd have to go through many background and safety tests, and if he was allowed in, he'd automatically have to sign multiple NDAs and he wouldn't be allowed to film ANYTHING. Thirdly, if he was allowed in, he'd only be allowed access to the area he wanted to see. He wouldn't be allowed to see anywhere else. Even Area 51 employees don't have full clearance to the whole facility. Sorry, but no heads-ups from Veritasium from what's in there. Lastly, about what's in there, sorry, but no aliens. Only extremely classified, Black-level secrecy projects, that would only be declassified if it was an emergency.
    So, there ya go. I'd advise against going, if you don't want you, your family and over 1.7 million people getting arrested.
