Time runs unnoticed and inexorably. It seemed that until quite recently it was summer and we were seeing off missions going to Mars. Already next week they begin to prepare for the finish - on February 9, the UAE probe Al-Amal should enter the orbit of the red planet, the Chinese Tianwen-1 probe on 10 February, and the rover will enter the Martian atmosphere on February 18, without an intermediate entry into orbit. NASA Perseverance.
"Al-Amal" ("Hope")
Launched on July 19, 2020, the United Arab Emirates mission successfully crossed the road to Mars and is going to be the first of the trinity to enter the Martian orbit. The mission team did not report the flight very actively, for example, there is information in the news about the first correction of the trajectory on August 17, but about the next ones, and there were at least two more of them, they were too lazy to report. The mission team has not yet published photographs or other interesting data from the device, but according to available information, things are going well. On February 9, "Nadezhda" will have a critical stage - within 27 minutes, in the radio shadow of Mars, it will autonomously slow down and switch from the flight trajectory to the Martian orbit. An error or malfunction can lead to both a flyby past the red planet and an orbit leading to a collision with Mars. But if everything goes wellThe UAE will become the second state after India that has managed to safely deliver the device to Mars on the first try.

The landing is planned to be carried out in the crater Jezero, which once was a Martian lake, and, possibly, there are traces of Martian life. Perseverance is an improved version of Curiosity, so we are promised a more accurate landing. And the fact that the technology of the "sky crane" has once safely landed the rover on Mars gives hope that the MCC and astronautics lovers will use less sedatives while waiting for a message from the rover.
