NASA’s rover Perseverance on Thursday neared its encounter with Mars, hewing to a trajectory that will plunge it into the atmosphere of the Red Planet to begin a sequence of maneuvers designed to avoid surface hazards and deposit the rover inside a crater that may hold remnants of ancient life. NASA anticipates the spacecraft will enter the atmosphere about 3:48 p.m. and deploy a parachute four minutes later. Touchdown is expected about 3:55 p.m.

Rough terrain will require spacecraft to use autonomous navigation system to avoid hazards

Has there ever been life on Mars?
