race ring
 n.— «“We’re literally going out there with the kind of tools you’d have in your garage,” said Colonel Fossum, the lead spacewalker for the mission. The astronauts will use a putty knife to smooth the surface of the “race ring,” the part that has been most damaged by the errant particles, and grease and cloths to see what works best at the task.» —“Shuttle to Take Big Science Lab to Space Station” by John Schwartz New York Times May 27, 2008.
