Author: Andrew Coates (MENAFN - The Conversation) Following 'seven minutes of terror' after it reaches Mars' upper atmosphere, NASA's Perseverance rover is expected to land on the surface of the red planet at 20:55 GMT on February 18. This is incredibly hard to do , with only about 40% of missions succeeding. As a member of the team that built the European Space Agency's Rosalind Franklin rover (we made the PanCam , the camera 'eyes' of the rover), which will set off for Mars next year, I will be holding my breath during the landing. There's so much at stake. Not only could the mission unveil some of Mars' best-kept secrets, and be a key part of future exploration to return a Mars sample back to Earth, it could also have important lessons for landing Rosalind Franklin.
