NASA’S MARS OBJECTIVES

Determine whether life ever existed on Mars

Focusing on an area that looks like it may once have had conditions favourable to microbial life, Perseverance will look for preserved biosignatures in rocks that formed in those ancient times.

Characterise the Martian climate

Studying the past climate of Mars also tells us about the possibility of ancient life there. To this end, the rover’s instruments will search for evidence of ancient habitable environments.

Characterise the geology of Mars

Perseverance will study the rock record to learn about the geological processes that moulded the Martian landscape, particularly looking for rocks that formed in water – one of the essential prerequisites of life.

Prepare for human exploration

With an eye on future visits by human travellers, Perseverance will try out methods of utilising natural resources for life support, as well as monitoring environmental conditions to inform future mission planning.
