This is stunningly good at first glance. And gets better when you think about it.
Just what percentage of commercial RC helicopters/drones make it to 75 flights before an accident requiring repairs? With outdoor overwinter storage. My observations at local RC flying fields and around town would indicate that it is single digit or less. And it is a much easier environment.
Yes but I'm certain those also doesn't cost the same that this one costs and how hand picked/tested his components must had been to endure such environment...
Very true. But most earthly RC helicopters/drones do not crash or stop operation because of failed components. The number one cause of mortality is operator error. With hanger rash (storage accidents) being next in line. And many are operated line of sight. None of them have any significant communications lag. Try flying your drone when you have to make all your commands and decisions several minutes to hours before the flight takes place, and you can only do your flight planning with satellite images. And where the classic earthbound response to avoid terrain etc. is to fly higher, the air at ground level on Mars is already so thin that climbing is next to impossible.
I'm not ready to say that NASA has their mojo back, but I could pretty easily go along with JPL never lost theirs.
