These amazingly artistic photos are by Michael Soluri, who photographed the tools used in the most recent Hubble repair mission, before they went into orbit:

The photograph[s were] taken by Michael Soluri in the clean room at the Goddard Space Flight Center just before the last repair mission, in the most restrictive conditions he has ever worked in. He was kitted out in a nylon “bunny suit”, with boots and latex gloves, and his equipment had to be disassembled and chemically bathed beforehand.

The full story is here. (Hat tip to Joel/@LunarPioneer for the article!)
