Flight 20 was a success! ✅ In its 130.3 seconds of flight, the #MarsHelicopter covered 391 meters at a speed of 4.4 meters per second, bringing it closer to @NASAPersevere's landing location.
How does a helicopter fly without an atmosphere? (0.087 psi). That is essentially a vacuum.
Ginny, keep on flying!

The lower gravity of Mars (about a third of Earth’s) only partially offsets the thinness of the 95% carbon dioxide atmosphere of Mars,[36] making it much harder for an aircraft to generate adequate lift.
The planet’s atmospheric density is about 1⁄100 that of Earth’s at sea level, or about the same as 87,000 ft (27,000 m), an altitude never reached by existing helicopters. To keep Ingenuity aloft, its specially shaped blades of enlarged size must rotate between 2400 and 2900 rpm, or about 10 times faster[10] than what is needed on Earth.[37][38]
The helicopter uses contra-rotating coaxial rotors about 1.2 m (4 ft) in diameter, each controlled by a separate swashplate that can affect both collective and cyclic pitch.[39]

Great stuff, thanks.
click bait... never again
Born on Mars on April 3rd, Easter eve. On Easter, the lil copter had survived that first night all alone in the cold.
Ginny is my favorite Martian.
Ingenuity *is* life on Mars. :)
As with the previous flights, this was the standard first announcement out of NASA-JPL.
Not an excerpt.
If you meant that the thread itself was click bait, well the info just is what it is.
Good news for the fans of little Ginny!
Last I heard the James Webb telescope was on-schedule and doing well too.
followed the link and all there was was a 3 second gif of the drone. I wont click into nasas twitter link again... no biggie, just sayin...
Ok Here’s something to consider. Mars has enough atmosphere to fly a kelocopter and that atmosphere is 93% CO2. There is 10 times as much CO2 in the martian atmosphere as there is in the earth’s atmosphere, and yet there is no green house effect. Mars gets up to 25 C in the summer at noon but goes below zero at night. CO2 becomes solid at the poles. How come we have warming and Mars doesn’t?
Ha! Mine, too.
The blades on Ingenuity are huge compared to the body they lift. Far, far larger in scale to a UH-1’s if Ingenuity’s body were the size of a UH-1. And they rotate at 2400rpm to generate the lift needed in Mars’ near vacuum.
Any warming Earth has is due to cycles of the sun, brought on by the slight irregularities in our orbit and our planet's little wobble. And earth's atmospheric CO2 is about four hundredths of one percent, wayyy less than 10%.
Oh I forgot the important part...WE DON'T.
