RE: NASA's Spacecraft, the "Perseverance" has successfully landed on Martian atmosphere

It is very impressive all the work they are doing to take man off the planet.And I think that is the main objective of all this, because in the face of the danger that the planet is becoming contaminated at very high levels and the increasingly certain possibility of not being able to save it, these technologies and discovery make it clear to me that this is the main purpose.

For me it is really surprising that they have taken a helicopter and even more so that they manage to fly it on another planet remotely, this is simply a genius! And perhaps it is the greatest achievement of man in all history.
