It's funny, the things you notice hanging upside down in space.
Astronaut John Mace Grunsfeld remembers a quirky discovery back in 1999. He had just arrived at the Hubble Space Telescope and climbed out of the airlock of Space Shuttle Discovery to begin a servicing mission. Clinging to a handrail running down the side of Hubble's gleaming exterior, he ran his eyes over the blue planet 350 miles below and tried not to think too hard about the yawning starry expanse behind him. The astronaut, Hubble, and Discovery, connected together, raced around Earth at 17,000 mph.
That's when he noticed the handprints.
"The outside surface of Hubble is covered with them—scuff marks and other signs of handling by astronauts," says Grunsfeld.
