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.

    It wouldn't be breaking the speed of sound on mars right?

      they need to send a few of those things up there, not just one.

            How to fly theres no gravity on mars,and no oxygen,

              what if it tips over??? (on MARS)

                this mean that a 50 cal would fly waaaayyy faster in mars

                      That doesn't impresses me much. My model helicopters easily reach 2500 rpm headspeed and can lift 8kg. It can stay in the air for 10 minutes. There are many Model Pilots who are able to construct a Mars helicopter with some seconds flighttime. I think JPL "invents" model helicopters that have been on the market for decades.

                        Flying RC heli's myself this is awesome....but this type of heli does exist in RC scale . I know he said its because of the size and weight but would a normal RC heli fly on mars ? maybe just with bigger blades.

                          How does it upright itself after falling over? How strong are the blades when they impact Martian regolith?

                          Great vid, can't wait for mission success.

                                          So my question is, what happens if it tips over? Does the rover just go over and pick it up?

                                                      So why don't you like build a box on the Rover to keep the thing warm and help recharge then when it would be able to have more flight time

A single or dual propeller copter actually has very complex mechanisms that tilt the propellers to maneuver the craft.
