The launcher's EPS upper stage is to be ignited three times. The flight's first EPS operation will be an 8-minute burn to place the upper stage and its ATV payload into an initial elliptical orbit with a perigee of 130 km. and a 260-km. apogee. Its second ignition, to occur 45 minutes later, will be a 30-second burn that circularizes the orbit and positions the EPS upper stage for its deployment of the ATV. A final EPS ignition is planned 90 minutes later, propelling the upper stage on a safe atmospheric re-entry for splashdown in the Pacific Ocean.
