Russell’s Teapot.
A lone white lawn chair on the surface of Mars
A giant ship that can transform into a giant robot maid, complete with a vacuum to suck planets’ air.

-Sincerely, totally not a cat
A single protein molecule.

That manhole cover from Operation Plumbbob.
“YOU ARE HERE” map.
TMA-2 / Zagadka / Big Brother (the Jovian monolith).
Sprinkle some water on the moon
Gonna steal an idea from Karl Pilkington and leave a dishwasher somewhere on Mars for one of the rovers to find.
