A flurry of Mars missions

A flurry of Mars missions

Going to Mars is non-trivial, since both planets revolve around the Sun and are hence in constant motion relative to each other. Earth and Mars are at their closest distance relative to each other every 26 months — and this is when Earthlings try to send missions to Mars.

NASA’s Perseverance Rover

The most sophisticated mission from an engineering standpoint, NASA’s Perseverance Rover, is en route to Mars, and is set to land on Thursday at Jezero Crater, which was likely filled with water in the past.

Perseverance is NASA’s 4th generation Mars Rover

The goal is to look for biosignatures in the dried up lake bed at Jezero Crater.

Tianwen-1

Tianwen-1, the first mission to Mars from China, successfully underwent orbital insertion on February 10. Tianwen-1 carries an orbiter, a lander, and a rover. China’s approach for landing a rover is somewhat different. Unlike NASA rovers, Tianwen-1 will orbit Mars for a few months before attempting to land in May this year.
