Company inks agreement with NASA Ames to design reusable,
sub-orbital space vehicle
SpaceDev has begun
designing a reuseable, piloted, sub-orbital space ship that could
be scaled up to safely and economically transport passengers to and
from low earth orbit, including the International Space Station.
The name of the vehicle is the "SpaceDev Dream Chaser."
SpaceDev's founding chairman and CEO, Jim Benson, recently
signed a Space Act Memorandum of Understanding with NASA Ames
Research Center director, Dr. Scott Hubbard. This non-binding MOU
confirms the intention of the two parties to explore novel, hybrid
propulsion based hypersonic test beds for routine human space
access. The parties will explore collaborative partnerships to
investigate the potential of using SpaceDev's proven hybrid
propulsion and other technologies, and a low cost, private space
program development approach, to establish and design new piloted
small launch vehicles and flight test platforms to enable
near-term, low-cost routine space access for NASA and the United
States. One possibility for collaboration is the SpaceDev Dream
Chaser project, which is currently being discussed with NASA
Ames.
Unlike the more complex SpaceShipOne, for which SpaceDev
provides critical proprietary hybrid rocket motor propulsion
technologies, the SpaceDev Dream Chaser would be crewed and
take-off vertically, like most launch vehicles, and will glide back
for a normal horizontal runway landing.
"This project is one small step for SpaceDev, but could evolve
into one giant leap for affordable, commercial human space flight,"
said Jim Benson. "I have been waiting for almost fifty years for
commercial space flight, and have concluded that SpaceDev, through
our unbroken string of successful space technology developments,
now has the technical capability and know-how, along with our
partners, and when fully funded, to quickly develop a safe and
affordable human space flight program, beginning with sub-orbital
flights in the near future, and building up to reliable orbital
public space transportation hopefully by the end of this
decade."
"I am delighted that we will be working with SpaceDev to help
meet the goals of The Vision for Space Exploration," said G. Scott
Hubbard, director of NASA Ames Research Center, located in
California's Silicon Valley. "Near-term, low-cost, crewed and
uncrewed routine space access is a key for realizing the nation's
Exploration Vision. I look forward to a long and fruitful
partnership with SpaceDev to explore the technologies for a new
class of exciting launch vehicles for future space
exploration."
The sub-orbital
SpaceDev Dream Chaser is derived from an existing X-Plane concept
and will have an altitude goal of approximately 160 km (about 100
miles) and will be powered by a single, high performance hybrid
rocket motor, under parallel development by SpaceDev for the
SpaceDev Streaker, a family of small, expendable launch vehicles,
designed to affordably deliver small satellites to low earth orbit.
The SpaceDev Dream Chaser will use motor technology being developed
for the SpaceDev Streaker booster stage, the most powerful motor in
the Streaker family. The SpaceDev Dream Chaser motor will produce
approximately 100,000 pounds of thrust, about six times the thrust
of the SpaceShipOne motor, but less than one-half the thrust of the
250,000 pounds of thrust produced by hybrid rocket motors developed
several years ago by the American Rocket Company (AMROC).
SpaceDev's
non-explosive hybrid rocket motors use synthetic rubber as the
fuel, and nitrous oxide for the oxidizer to make the rubber burn.
Traditional rocket motors use two liquids, or a solid propellant
that combines the fuel and oxidizer, but both types of rocket
motors are explosive, and all solid motors produce copious
quantities of toxic exhaust. SpaceDev's hybrid rocket motors are
non-toxic and do not detonate like solid or liquid rocket
motors.
