Can't wait until the SpaceX's Starship land the next gen Mars Helicopter that might be 10-20x bigger in 2-4 years.

- spookthesunset 5y agoKnowing spacex, they will deck that thing out with 4K video even if it means dropping a few satellites into Martian orbit to act as relays. My understanding is that video requires power to transcode and compress, and power is a scarce resource. This is especially true on ingenuity, which is powered by six 18650 batteries. And most of that power is dumped into just keeping it warm enough to function, not into actually flying. https://rotorcraft.arc.nasa.gov/Publications/files/Balaram_AIAA2018_0023.pdf https://rotorcraft.arc.nasa.gov/Publications/files/Balaram_A...
- alach11 5y agoWouldn't transcoding the video still produce the same amount of heat?
- sgt 5y agoNot that much as it will no doubt be hardware accelerated.
- alach11 5y agoMy point is that if you're spending electricity to generate heat, you can divert as much as you want to do calculations with no reduction in the amount of heat generated.
- FuckButtons 5y agoThe problem I suspect is where the heat is going, heating up a logic board won’t do much to stop the motors freezing.
- BHSPitMonkey 5y agoBattery-powered helicopter designs don't really scale on Mars any better than they do here on Earth. At higher vehicle masses, you'd need larger/heavier motors to get the larger/heavier blades turning as quickly as they'd need to (and in much lighter air than we have here).
