The New Shepard is launched vertically from West Texas and then performs a powered flight for about 110 s and to an altitude of 40 km (25 mi). The craft's momentum carries it upward in unpowered flight as the vehicle slows, culminating at an altitude of about 100 km (62 mi). After reaching apogee the vehicle performs a descent and restart its main engines a few tens of seconds before vertical landing, close to its launch site.[74][better source needed] The total flight duration is planned to be 10 minutes.
