After the rest period, robotic arm operators Karen Nyberg and Ron Garan stowed the orbiter boom sensor system inside the shuttle’s payload bay and powered down Discovery’s robotic arm.
The boom was used to inspect Discovery’s heat shield Wednesday. A review of the space shuttle tile imagery has not revealed any issues and the team is continuing to review imagery of the reinforced carbon-carbon material. A final report from analysis of the data is expected Friday.
The crew conducted an orbit adjustment burn at 3:20 p.m. using the right orbital maneuvering system engine. That adjustment enables an additional landing opportunity at the Kennedy Space Center on Sunday, if the shuttle is not able to land on the two opportunities on Saturday. Saturday opportunities at Kennedy are at 10:15 a.m. and 11:50 a.m.
The crew is scheduled to begin its sleep period at 6:02 p.m. and awaken at 2:02 a.m. Friday.
