On April 7, 2021, NASA posted a selfie of the Perseverance rover by an Ingenueiti helicopter. Both devices have been on the planet for 46 Martian days.


The rover is located at a distance of about 4 meters from the helicopter, so as not to block the possibility of charging from the onboard solar panel, which is located above the blades.


The Perseverance selfie with Ingenuity was stitched together from 62 separate images taken while the rover's base cameras were looking at the helicopter, and then again when it was looking at the WATSON camera.



The first flight of the Martian helicopter should take place on the evening of April 11. It is planned that it will last about 30 seconds, and the rotation speed of its two blades in the process will reach 2,537 rpm. The UAV is programmed to independently rise vertically a few meters, hover, and then gently descend back to the surface. NASA employees will receive and publish the first footage of this flight on April 12. The Perseverance rover will also monitor the helicopter's flight from a distance.


Currently, specialists from NASA's Jet Propulsion Laboratory (JPL) are simulating the local wind rose based on measurements made by the Mars Environmental Dynamics Analyzer (MEDA) instrument onboard the rover. The exact time of the first launch of the helicopter depends on this data.


On April 4, the Ingenyuiti helicopter separated from the rover in normal mode and landed from a height of 10 cm from its belly to the surface of the planet.


On April 5, NASA reported that the helicopter successfully survived the first Martian night offline. Its onboard systems withstood an external temperature of around -90 ° C. Now the helicopter is independently charging its batteries and preparing for the first flight.
