SS1 orbital parameters
From Jonathan's Space Report No. 529, 2004 Jun 28
http://www.planet4589.org/jsr.html Nevertheless this is a historic moment, marking the real dawn of commercial human spaceflight. The trajectory was highly suborbital, with a perigee close to the center of the Earth - inertial orbit parameters at apogee were about 6374 x 100 km x 35.0 deg. The inertial velocity at apogee was probably at most 0.3 km/s; if they had launched east instead of west they would have reached 0.5 km/s. The velocity needed for orbit at 100 km is 7.8 km/s, a big difference. |

In my view this is a very rudimentary system, purely there to show it can be done, but then it already has been. What is required for real public access, is some form of runway to space system that does not rely on being carried up under another aircraft. You also need some form of air breathing engines for loitering when you come down, or you might have a problem if your trajectory is a bit off beam!
