How would throwing a spacecraft designed to land itself in a world with one third of Earth's gravity out of a helicopter test anything?
On Mars, if it was true (we can’t be sure up to when we will really measure it), the gravity would be 38% of the earth’s.
But you, before sending Curiosity to Mars, must test it to verify if that flying crane is able to slow down velocity from 360 km/h to 0 km/h and to
land Curiosity softly on that planet.
Therefore you build an identical spacecraft with more power, able to land on the earth, doing all the things by itself
You can’t send a very expensive probe to Mars without testing it on the earth
If you had done it, you would be proud to show that wonderful spacecraft able to do incredibile things
Instead you have not invented that astonishing spacecraft and you can show nothing
Try to image: people are on a large field. A helicopter comes with vertical height 3 km. A big metallic base with 4 rocket engines is parachuted down.
The parachute slows down its velocity, then the parachute detaches and the 4 engines fire.
That big metallic base continues its fast descent and, instead of tilting in every direction, is able to keep horizontal attitude.
At the end it is able to land Curiosity softly with cables. And it does all these things by itself without pilot.
It would be amazing, astonishing. All the people would be incredulous, unable to believe.
You landed 6 big LEM on the moon but you never tested them at Langley Crane. Another big hoax.
