NASA's Perseverance rover lands successfully on Mars
This is the second one-tonne rover put on Mars by the US space agency.The first, Curiosity, was landed in a different crater in 2012. It trialled innovative descent technologies, including a rocket-powered cradle, that Perseverance has also now put to good effect.Controllers will spend the coming weeks commissioning the new rover, checking that none of its systems were damaged in what would have been a rough ride to the ground.
Many pictures will be sent back to get a sense of the surroundings.The targeted landing zone was just in front of what looks from satellite pictures to be the remains of a vast delta - a feature built by rivers as they push into a wider body of water and dump their sediment.Scientists hope that incorporated into this material are tell-tale signatures of past biology.Perseverance will sample the base of the delta and then move towards the rim of the crater. It's there that satellites have detected carbonate rocks, which on Earth are particularly good at trapping biological activity.Perseverance has a suite of instruments that will researchers back on Earth will use to examine all these formations in detail, down to the microscopic level.
