NASA’s most elaborate life-hunting Mars rover ready for liftoff – Sydney Morning Herald
The rover Perseverance will follow China’s rover-orbiter combo and a United Arab Emirates orbiter, both launched last week.
This unprecedented effort will involve multiple launches and spacecraft and cost more than $US8 billion ($11 billion).
We dont know if life existed there or not. But we do know that Mars at one point in its history was habitable, NASA Administrator Jim Bridenstine said on the eve of launch.
The US remains the only country to land successfully at Mars. If all goes well next February, Perseverance will become the ninth US spacecraft to operate on the Martian surface.
