Crewed Suborbital Vehicles - sense or nonsense

About the activities of Virgin Galactic and Blue Origin

 

1. Virgin Galactic

V.G. uses an airplane-like vehicle called "Space Ship Two" with a hybrid solid-fuel motor. After separating from its carrier aircraft, it climbs almost to the Karman line and then lands on a runway, steered.

The predecessor, "SpaceShip One", was a smaller experimental model, constructed by Scaled Composites, with only one pilot. It has made six flights with an active motor and won the Ansari X-Prize for reaching the altitude of 100 km.

2.  Blue Origin


B.O. uses a liquid-fueled and vertical starting one-stage launcher called "New Shepard" with a capsule on top that has an escape motor. After separation, the capsule climbs without extra drive up to the Karman line and then lands by parachute. The launcher lands reusable by the engine.
