Another success for Perseverance - making oxygen from Mar's atmosphere

Good research, but the article is probably wildly underestimating return requirements.https://www.jpl.nasa.gov/news/nasas-perseverance-m...
It's probably more likely to be a Starship on Mars, than an alternative at this time.
Starship will require vastly more than 25t of propellant.
Second flight went well https://www.space.com/mars-helicopter-ingenuity-se...

In the greater scheme of things that is far better than the drone flight
tting out stuff too to be brought home.
Third choppa flight completed OK.

5 meters up and 50 meters off to the site and back.

50 meters! Brilliant. Is it safe to declare Ingenuity a success?https://www.youtube.com/watch?v=kNx9hcrUpww

I'd say it's a success. I notice it lands back close to but no exactly where it took off from, how is it navigating?
There’s an interview here with the senior software engineer on the project:https://spectrum.ieee.org/automaton/aerospace/robo...
“We use a cellphone-grade IMU, a laser altimeter (from SparkFun), and a downward-pointing VGA camera for monocular feature tracking. A few dozen features are compared frame to frame to track relative position to figure out direction and speed, which is how the helicopter navigates. It’s all done by estimates of position, as opposed to memorizing features or creating a map.”
“ We also have an inclinometer that we use to establish the tilt of the ground just during takeoff”
Interesting that they've only got two more flights, the BBC says:
Nasa officials have granted the Ingenuity engineering team two more flights before Perseverance is commanded to get on with its primary mission of searching for life in Jezero.
I wonder how much scope there is for the last mission to fly as far as possible to see what the limits of the batteries are, or maybe fly on top of a hill to take a big panoramic picture. Obviously getting the data back to Perseverance and then back home is the issue in those scenarios.

Or attempt to hop the flights to keep up with the Rover with no concern if it doesn't make it. Nasa officials have granted the Ingenuity engineering team two more flights before Perseverance is commanded to get on with its primary mission of searching for life in Jezero.

Amazing tech and achievement.
Thought they were going to use the drone as a pathfinder.
I don’t think that was the plan. I hope that now it’s proven its capability, they consider making use of it. Thought they were going to use the drone as a pathfinder.

Brilliant, thanks for that info https://spectrum.ieee.org/automaton/aerospace/robo...
