The shuttle's Thermal Protection System and Reinforced Carbon Carbon  are cleared for reentry. We are adding a tile survey tomorrow that  should last about 45 minutes. We had a little "pan and tilt" error and  missed some tile. There isn't an issue. We just want to look at it.
   
  We had an issue on today's spacewalk with a bolt critical to removing  the Wide Field Planetary Camera 2. We tried using different tools and  were eventually able to remove the bolt using a reconfigured ratchet  tool.
 
  If the bolt broke, there's nothing else we could have done. We would not have been able to install The Wide Field Camera III.
 
  The WFPC 2 will eventually end up at the Smithsonian's Air and Space Museum.
 
  They replaced the SIC&DH unit as well. That, with the WFC III  installation, makes two of our three top priorities accomplished. The  third priority is the installation of the new gyroscopes.
 
  We  were able to install one of the three latch-over center kits. This was  a get-ahead task for EVA 3. They had some difficulty with the other  two, installing a latch repair on one of the bolts, and partially  installed a second lock. That door is now secure for when it's  revisited on the mission's third spacewalk.
