> At 11:55 p.m. EDT, space shuttle Endeavour undocked from the International
> Space Station. Endeavour spent 11 days, 17 hrs and 41 minutes docked to the
> orbiting laboratory. At undocking, the spacecraft were 215 miles above LaPaz,
> Bolivia.The fly around of the space station will begin at 12:22 a.m., with
> Pilot Greg Johnson maneuvering Endeavour to circle the station at a distance
> of about 600 feet. The shuttle crew members will take detailed photographs of
> the external structure of the station, which serves as important documentation
> for the ground teams in Houston to monitor the orbiting laboratory. Once the
> shuttle completes 1.5 revolutions of the complex, Johnson will fire
> Endeavour¹s jets to leave the area. Nearly two hours after undocking a second
> firing of the engines, which would normally take the shuttle further away,
> will serve as the first maneuver to bring Endeavour back toward the station
> for the Sensor Test for Orion Relative-navigation Risk Mitigation, or STORRM.
> Commander Mark Kelly will pilot Endeavour for the re-rendezvous.The test will
> characterize the performance of sensors in Endeavour¹s payload bay and
> acquisition of reflectors on the shuttle¹s docking target at the station. The
> re-rendezvous will mimic the Orion vehicle¹s planned rendezvous trajectory and
> will approach no closer than 600 feet to the station. Endeavour is targeted to
> approach the station to a point 1,000 feet below and 300 feet behind the
> station at its closest point.
