JPL tweeted: "the Mars helicopter is preparing to do something unprecedented, that is, to fly with controlled power on another planet. Now the first flight is scheduled for April 11, and the data will reach the earth on April 12. " < / P > < p > the helicopter under the willpower has been deployed from the belly of the rover to prepare for its first flight. On March 21, willpower released a protective shield to help the helicopter withstand a dangerous landing through the Martian atmosphere. It will take some time for the smart to launch and start flying. NASA said in a statement that it will take about six Martian days, each of which is equivalent to about 24 hours and 40 minutes on earth. < / P > < p > picture: This is NASA's flight route map for its Mars helicopter. < p > < p > on March 21, a member of the willpower team tweeted: "the smart is folded up, placed side by side, and locked in place, so we need to unfold it before putting it down. However, first of all, we need to go to the designated "helipad", which is a few days' drive away < / P > < p > once safely deployed on the surface of Mars, the test flight of the smart will begin soon. The mission team hopes to launch the UAV within 30 Mars days (about 31 Earth days) after the deployment.
