A docked Progress 25 cargo craft will fire its thrusters on July 21 and 23 raising the International Space Station's orbit. The reboost provides the proper phasing for an upcoming Progress 26 launch and docking. The Progress firing also clears the station after the Early Ammonia Servicer (EAS) is jettisoned during a July 23 spacewalk and provides flight day three rendezvous opportunities when space shuttle Endeavour arrives on mission STS-118. In advance of the reboost, the crew is testing the command and data telemetry of the Russian computers.
