After a few hours of rest, the crew members will stow the orbiter boom sensor system (OBSS) inside the shuttle’s payload bay as well as power down Discovery’s robotic arm.
The crew will also conduct an orbit adjustment burn at 3:20 p.m. CDT using the right orbital maneuvering system (OMS) engine. That adjustment will change the shuttle’s orbit by seven feet per second and will enable 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.
The crew was awakened at 2:32 this morning to “Crystal Frontier” by Calexico. It was played for Commander Mark Kelly. The crew is scheduled to begin its sleep period at 6:02 p.m.
