Gale crater
Curiosity · since 2012 · on Mars, 4.59° S, 137.44° E
Curiosity landed on the floor of Gale crater and has been climbing Mount Sharp, a layered mountain 5 km high in its middle, reading billions of years of Martian climate in its rocks. Look for the Earth as a bright evening or morning 'star'.
Stand at Gale crater 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.
