Please update me on theoretical propulsion systems and any current plans
for the new space shuttles. I will soon be a student of physics
and one day a space systems engineer.
Thank you for your time and response.
The NASA KSC homepage has links to a lot of Shuttle-related information,
including the upgrade program and the X-33, X-34 and X-38 programs, and
links to pages for many other rockets:
Speculation on future means of propulsion can be found at:
