First Flight on Another Planet!

  • Published on Aug 10, 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.

    Why not a landing pad on the larger rover with charging capabilities to recharge the helicopter

    Not just flying on another planet. But flying on another planet with rarefied atmosphere and low gravity. In other instances it will need different calibration.

    surely there is some plants that can work in such harsh environments and photosynthesize or we could make one. Then just send it to mars and let it create an atmosphere so its less volatile.

    Hey look, they are trying to recreate the technology to fly to the moon and fly around the moon again. If we were only as technologically advanced today as we were 50 years ago.

      If only we had some evidence of it being real then people could stop using that claim as evidence that the moon landings were faked.

    The speed of sound is lower then on earth right did they took that into consideration they probably have (but what is the speed of sound on Mars is it just 1% of the speed one earth or are there other variables)

    Would a hot air or hydrogen balloon-style design work on Mars?

      Not easily. The atmosphere on there is very thin so there aren't many options. Plus, you have to get it there. A balloon can easily break. And considering the winds that happen, it might not be the best option.

    Maybe some day they could mount a reasonably high power laser on the ground module that could be directed toward the UAV to help keep it warm and thus give it more time aloft.
    Also they could build a deployable docking station away from the ground rover that could help recharge its batteries once it lands so it could make more than one flight per day.

    Have they provided a dust cleaning system for solar panels? On Mars a lot of dust and sand that will settle on them.

    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...

    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?

    Great Vid.

    this made me wonder. Is the speed of sound constant?

    • Релёкс84
      Релёкс84 Month ago +1

      It depends on the medium: it is much faster is water for instance, and even faster in rigid materials like metal. When it comes to gas, the speed of sound varies a bit depending on the composition and temperature.
