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.

              II have an idea! Bring a camera so we can watch it as it takes off. Just place the camera in the sand, move the rover away so it's a bit away, but still visible, then take off. Not only will it probably be super cool, *if* something were to go wrong, but it might also give more data as to what. Then later, the rover picks the camera back up... Some... How...

                  Bolaram is the kind of name you associate with a poor Indian peasant who is at the mercy of a cruel landlord, add a 'Bob' at the beginning and you have this NASA aerodynamic scientist making the first copter that would fly in Mars.

                                the intensity of the air is less than that of the earth, the blades should be more inclined to suck up more upward force otherwise it would be like running with a neutral engine or increasing the engine revs but it would cause too much overheating or give a suitable inclination to create the right vortex of air for detachment from the ground.then I add a quadcopter much better would be more stable

                                  At first, I didn't think of recharging the batteries, and I was thinking: "90 seconds, and that's it? Entire mars mission done!" Then, of course,r they are rechargeable.


                                  Now wondering if the small panel on top is enough to be self-reliant, or if the rover would be able to charge it too. And if it is self-reliant for power, I suppose it stays close to the rover to be able to communicate back to Earth?

                                                Why not have all the computer components on the rover and just use a wireless transmitter to do the work? It would decrease weight a lot or you could just put more batteries instead of circuit boards.

                                                    As an x-rc heli pilot I was a little underwhelmed by the rpm number. 1500mm dia blade helis often push 2000-2100 rpm so I was expecting more.

                                                          The Space elevator's idea need a strong material for the cables to lift the loads from earth surface. We need a very long cable (about 300km minimun) that no be broken by His own weigth. The second problem is build a light powerful electric motor to lifting the elevator. When we solved this problems maybe we can build it.
