All systems were a Go !!

All systems were a GO as NASA made history on Monday, April 19, 2021.
The agency launched its Ingenuity helicopter into the atmosphere of Mars around 3:30 am ET, marking the first powered, controlled flight of an aircraft on another planet.

The flight was streamed live on NASA's website at 6:15 a.m ET, when the data from the flight reached Earth.

To send data round trip from Earth to Mars and back to Earth again is approx a 4 hour delay, and that delay increases with the amount of data being sent.

That helicopter is built so light, the blades alone weigh approx the same weight as six 25 cent pieces (6 quarters) or something like that.
The machine that toke flight on Mars can not actually fly on Earth, due to gravity and atmospheric differences.
Its blades RPM is somewhere around 2300 and 2900 RPM as opposed to earth Helicopters at around 500 RPM.
They could have set them at a higher RPM but If them blades break the speed of sound then things can and will become hazardous :eek:

I saw all this on a science tech video (ytub) awhile ago.

Veritasium is the channel.
Its quite an intelligent channel :)
