Dream Chaser is a
reusable space plane designed to carry from two to seven people
and/or cargo to orbital destinations such as the International
Space Station. It is being developed by Sierra Nevada Corporation
(SNC) Space Systems.

Dream Chaser is a
reusable lifting-body space plane carries up to seven crew and cargo
to and from low Earth orbit. It is part of NASA's Commercial Crew
Program to supply crew and cargo to the
The Dream Chaser
space plane vehicle design
derived from NASAís
HL-20 which had years of development,
analysis, and wind tunnel testing by the Langley Research Center.
Dream Chaser will
be launched vertically
on a United Launch Alliance (ULA) Atlas V Launch Vehicle. It will be
capable of free
flight in low Earth orbit and of docking to the International Space
Station & other orbital destinations.
When returning to
Earth it will use a low-impact
horizontal landing on a conventional runway. The vehicle has a large cross-range
with frequent landing opportunities. It is designed for simple
maintenance and quick turnaround.
The vehicle has a low-g reentry (<
1.5 gs) which protects crew & science experiment return samples.
Dream Chaser has crew
safety features, such as non-toxic propulsion systems. The on-board propulsion system
is derived from SNCís
SpaceShipTwo hybrid rocket motor technology.
The first orbital
flight test of the Dream Chaser is not expected before 2016. A fleet
of Dream Chaser spaceplanes maybe built in the future.
Mass: 11,340 kg
Volume: 16.00 m3
Wing Span: 7.00 m
Crew: Up to 7.
Endurance: At least 210 days
Re-entry: Less than 1.5 g
* The Dream Chaser
was publicly announced on September 20, 2004 as candidate for NASA's
Vision for Space Exploration and later Commercial Orbital
Transportation Services Program (COTS).
* SpaceDev was
acquired by Sierra Nevada Corporation in December 2008. On February
1, 2010, Sierra Nevada Corporation was awarded $20 million in seed
money under NASAís Commercial Crew Development (CCDev) phase 1
program for the development of the Dream Chaser.
original HL-20 team made to the successful Dream Chaser Flight
Vehicle Captive Carry test completed on May 29, 2012. This test
marked the first full-scale flight of the HL-20-derived vehicle, as
well as the beginning of the Dream Chaser's flight test program. The
flight met all the pre-established flight test goals and was a
significant step towards preparing the vehicle for an autonomous
Approach and Landing Test (ALT).
* On 12 June 2012, Sierra Nevada Corporationís (SNC) Space Systems proudly announced
the commemoration of the fifth year of its very successful
relationship with NASA Langley Research Center as partners in the
design and development of the Dream Chaser Space System (DCSS). SNC
and NASA Langley joined forces to update NASA's HL-20 lifting body
vehicle design into SNC's Dream Chaser orbital crew vehicle, which
is being developed as part of NASAís venture into commercially
provided crew transport.
Corporation and NASA's Langley Research Center announced five years
of partnership on the Dream Chaser Space System.
