What is there
Viking 1 lander (Lander, NASA)
Landed on 20 July 1976, seven years to the day after Apollo 11, and worked for more than six years. It took the first colour photo from the surface of Mars, measured its weather every day, and tested the soil for life. It stands here still.
Stand at Chryse Planitia 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.
