It completely burned up upon reentry. Back up in the space station, astronauts had had to adapt to being short a few tools. During her next spacewalk, Heidemarie Stefanyshyn-Piper again had to lubricate some components but didn't have a grease gun. She dipped her glove in grease and applied it by hand.

Authors By Jonah N. Routine altered for next outing Two grease guns were in the bag that got away. That leaves just two guns aboard the space shuttle Endeavour and space station, each with a different nozzle for reaching different parts of the clogged joint. Meanwhile, the bag that got away was still in the neighborhood of the shuttle-station complex but was expected to fall out of orbit fairly soon. The gummed-up joint is full of metal shavings, the result of grinding parts.
Over the course of four spacewalks, astronauts will clean and lubricate the joint and replace the bearings inside, and do a little work on another joint. The first three spacewalks concentrate on the bad joint, the fourth will focus on the good joint. The joint is supposed to keep the solar wings on the right side of the space station pointed toward the sun.
A twin on the left side is operating fine, but the astronauts will squirt on some extra grease as a precaution. In other space station business Wednesday, the astronauts hooked up some of the gear that was delivered by Endeavour, including a new recycling system for turning urine into drinking water.
