With respect to Blue Origin, a friend of mine & I were speculating on what uses other than tourism a reuseable "rapid-turn" suborbital capability might have. We thought about a Hohmann-style rendezvous with a vehicle in LEO, and from our calculations you could get about 90 seconds of proximity (<1 km) to an orbiter with relative (although variable, depending on specific times) velocities of just a few meters per second during the apogee (provided inclinations, etc. were matched). This was based on a notional 200 km ASL orbit for the target vehicle.
What do the experts here think? Could something very like Blue be used to inexpensively resupply LEO space stations if a cargo capsule jettisoned at apogee had its own trim motor to increase "hang time" near such stations (or execute a rapid hard rendezvous)? -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

un-needed quote removed Sorry, no. There's much more than altitude involved in being in orbit. You'd simply destroy the target vehicle with a 25,000 KPH collision! Bob Shaw -------------------- Remember: Time Flies like the wind - but Fruit Flies like bananas!
