Project Daedalus was a 1973-77 study project of the
British Interplanetary
Society
to send an robotic, nuclear-powered spacecraft to
Barnard's Star, a very dim red
dwarf that may contain two Jupiter-class
planets. Accelerating to 12-13 percent of
light speed using a deuterium/helium-3 nuclear fusion reaction to
provide thrust,
Daedalus was designed to deliver a sensor platform and return data and images
while passing through Barnard's just 56 years after its departure from Earth.

The wedge shaped
X-33
was being developed cooperatively
by NASA and Lockheed Martin Skunk Works. It was to be a
half-scale prototype of a Single-Stage-to-Orbit (SSTO)
Reusable Launch Vehicle (RLV) with two
linear
aerospike
engines that would fly at 15 times the speed of sound and
replace the Space Shuttle. On 3/1/2001, however, market
competition for intended commercial applications from
lower cost Russian, Chinese, and European rockets, as well
as a fuel tank design setback and cost-overruns, led NASA
to cancel the project despite good engine tests and near
completion (90 percent) of the hull. Efforts by the U.S. Air
Force to takeover X-33 funding for meeting its near-term
space deployment needs have been blocked repeatedly.
