Watch NASA’s exciting mission trailer: Perseverance to Mars



Mars Perseverance Landing

After nearly 300 million miles (470 million kilometers), NASAPerseverance rover completed its journey Mars But on February 1

8, 2021, to reach the surface of the red planet, it must pass the painful final stages of entry, descent, and landing.

The mission uses technological innovations that have been successfully demonstrated, especially in terms of entry, descent and landing (EDL). Like NASA’s Curiosity rover, the “Mars 2020” spacecraft also uses guided entry, descent and landing systems. The landing system of the “Mars 2020” mission includes a parachute, a descender, and a method called “skycrane maneuvering” to lower the rover. Tie the rope to the surface in the last few seconds before landing.

This type of landing system has the space to land a large and heavy rover on the surface of Mars, which is more accurate than the landing area of ​​Curiosity before landing. “Mars” in 2020 goes one step further. It adds new entry, descent and landing (EDL) technologies, such as relative terrain navigation (TRN). This advanced navigation system allows the rover to bypass the Martian atmosphere when it descends, thereby detecting and avoiding dangerous terrain. The microphone enables engineers to analyze entry, descent and landing. It may also capture the sound of the rover at work, which will provide engineers with clues about the health and operation of the rover, and is an audible enjoyment.
