First Flight on Another Planet!

  • Published: 10 August 2019
  • 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.

        Veritasium is where the best tech reporting is at! Do these things have multiple copies of os and other software... How do they handle mission critical processing and memory with the higher probability of cosmic bit flips associated with space travel and thinner atmospheres?

            Do you think a craft like this, if in the vicinity, to clean the solar panels of opportunity like dust storms in the past have or do you think the cold has already damaged the electronics to where the rover is unusable?

                Ok, they can mimic the mars gravity on flight forces, but they can't on accelerometer sensor. Good luck control engineers of autonomous flight!

                    I realy do hope it all works out and get some data from our little flying buddy. ALSO Not only would having the craft take a "Selfie" of the rover its deployed from perhaps give the public something to look at and feel good about, but I imagine it'll provide a number of tests so long as the picture actually is recieved (I imagine tests such as : Does it (the helicopter) work? Does the camera(s) work? Is the rover ok? Can we fly stably enough to take pictures? What is the area around the rover like?)

                                      and as a RC helicopter pilot, i want to have a go.

                                            Interesting. I hope NASA will give the public all the raw photos it takes. They could probably use the Rover's claw to recover and upright it if the wind blows it around, and the MH could do a flyover before landing to blow dust off the Rover's solar panels (or will it be nuclear-powered?).

                                                  How will this craft handle being tipped on its side due to landing on rough ground?

                                                    @Thomas Frühwirth - not according to the pictures from the rovers that are already there. I can only assume they have put the smarts into the copter to make it examine the ground carefully before landing. Clever stuff if they have.

                                                    Mike Collins same question here... how will it launch from an angled surface? How can it land there? Is mars mostly flat so we don’t have to care?

They could be honest with me, and I with them. Reading your words, what you wrote, how you were lonely sometimes and afraid, but always brave; the way you saw the world, its colors and textures and sounds, I felt--I felt the way you thought, hoped, felt, dreamt.

Could you follow this up through a comment or another video detailing how sound would work on mars as there is less air? I mean I can obviously tell that there will be less sound due to lack of moving particles. I'm more curious to what the extremes are on that side of the.....hmm, how do you call that....... other side of the dark matter? Ah who cares, I'm just curious :3

I asked my great granny if these things are really what they claim. She laughed and replied, "We have way too many _domestic_ problems already and all we do is fantasize. That's yet another problem on its own". Then, I got the message immediately.
