Opportunity's last stop
Perseverance Valley · June 2018 · on Mars, 2.19° S, 5.53° W
Where Opportunity fell silent, partway down Perseverance Valley on the inner slope of Endeavour crater's rim, after 45 km of driving.
What is there
Opportunity (Mars Exploration Rover, NASA/JPL)
Designed for 90 days, it worked for almost 15 years and drove 45 km — a record for driving on another world. A planet-wide dust storm in June 2018 covered its solar panels; its last message, roughly translated by a reporter, became "My battery is low and it's getting dark."
Stand at Opportunity's last stop in Stellingo: the ground is shaped from orbiter elevation maps and photos, the hardware is placed where it really is, and the sky above — the Sun, the Earth, the stars — is the real one, at any date you choose.
