Now that it has landed, the rover – and a helicopter named Ingenuity that will undertake the first ever flight on another planet – will get to work exploring Mars in search of clues about its ancient past. That will include attempting to understand whether the planet was ever habitable, and scouring for clues of past life on its surface.
The arrival on Mars brought an end to a journey of months and 300 million miles. It finished off a perilous entry, descent and landing process that saw it hurtle through the atmosphere, slow down to a safe speed, and then use a highly-advanced “Terrain Relative Navigation” system that will allow it to adjust where it lands to ensure it can safely drop down onto the surface.
