Ingenuity's First Black-and-White Image From the Air: NASA’s Ingenuity Mars Helicopter took this shot while hovering over the Martian surface on April 19, 2021, during the first instance of powered, controlled flight on another planet. It used its navigation camera, which autonomously tracks the ground during flight. Credits: NASA/JPL-Caltech. Full image and caption >
The small rotorcraft made history, hovering above Jezero Crater, demonstrating that powered, controlled flight on another planet is possible.
Monday, NASA’s Ingenuity Mars Helicopter became the first aircraft in history to make a powered, controlled flight on another planet. The Ingenuity team at the agency’s Jet Propulsion Laboratory in Southern California confirmed the flight succeeded after receiving data from the helicopter via NASA’s Perseverance Mars rover at 6:46 a.m. EDT (3:46 a.m. PDT).

They will look back on these as the good old days when NASA was something other than a tool for social engineering.
I’m curious how that device works, considering how thin the atmosphere is on Mars, how do the copter blades provide lift to the drone...
Looks like counter rotating rotors. Must spin pretty fast. I don’t recall the make up of Mars atmosphere.
“NASA plans a series of tests before that first flight to fire up Ingenuity’s four rotor blades (they spin at up to 2,537 revolutions per minute)”
An Earth one does 500-600 per minute.
Don’t quote me on this but I recall that it has to do with blade rotation and this guy is in the neighborhood of 2500 rpm which is suppose to be six times the normal needed to lift off due to the lack of atmosphere.
They should fly it over the rover and blow that dust off of it.
Why? The rover is nuclear powered. Doesn’t matter how much dust is on it really.
Here’s an article about the atmosphere on Mars..
It’s supposedly 100 times thinner than the atmosphere on Earth....or approximately 1% of the density of Earth’s atmosphere....
I read in another article the Mars atmosphere is like being 22 miles up in Earth’s atmosphere...
Over 95% of the atmosphere is made up of C02....

It’s endless miles away from that Insight lander you linked to.
Actually, I think we will look back on these days as the peak of science before it all became politicized and funding ran out due to the coming collapses of world economies.
C02 is heavier than air so having more mass helps negate the thin atmosphere. I think.
See Post #4.
“Over 95% of the atmosphere is made up of C02....”
Just as Greta suspected, climate change!
“Over 95% of the atmosphere is made up of C02....”
And yet the planet is ‘cold as hell’, at least according to Elton John.
“Actually, I think we will look back on these days as the peak of science before it all became politicized and funding ran out due to the coming collapses of world economies.”
Actually, I think we’re 50-plus years beyond ‘peak science’, when you look at what we were doing back then.
But yea, it’s over - we let the Left win.
It’s a wonder with the blades spinning that fast in the thin atmosphere of Mars that it doesn’t come apart and disintegrate...
That’s a different rover.
