Subject field(s)
  • Astronautics
CONT

The Return to Launch Site(RTLS)... abort mode is designed to allow the return of the orbiter, crew and payload to the Kennedy Space Center launch site, approximately 25 minutes after lift-off. The RTLS profile would accommodate the loss of thrust from one main engine between lift-off and approximately four minutes and 20 seconds, at which time not enough MPS propellant remains to return to the launch site. An RTLS would also be used if a time-critical failure occurred that required the earliest possible landing, such as a cabin leak or major cooling system failure.

Record 4 2003-02-27

English

Subject field(s)
  • Launchers (Astronautics)
CONT

Analyses of launch-vehicle data obtained during the flight revealed that launch-vehicle propellant depletion occurred before the velocity cut-off system was armed and before the thrust chamber abort switch was disarmed. This combination of events resulted in an abort signal being transmitted to the spacecraft from the launch vehicle.
