Hydroxy-terminated
polybutadiene (HTPB) is basically tire rubber that is
burned with nirtroxous oxide, or laughing gas.
Because these
substances are stored separately during flight, they are
extremely more safe than traditional fuels.
Additionally, the new fuel is more environmentally
friendly, adding far less ammonium perchlorate and
aluminum into the atmosphere.
This fuel system,
combined with Burt Rutan's design enable SpaceShipOne to
be an unbelievable 97 percent reusable.
This ability to quickly
and safely reach the weightlessness of space makes
SpaceShipOne a potentially immense resource for
universities and businesses that are used to paying
millions to NASA to do experiments in weightlessness on
board the shuttle, or on the space station.
Much like the race to
the moon helped develop today's computer and
communication's innovations, as well as developing
simple utilities, such as velcro, the private space
industry will also lead to significant discoveries and
innovations in the coming years.
These innovations alone
could help private space develop untold new industries
and jobs, completely independent from the private space
race itself.
