Dream Chaser glides in first test - AVweb video













Sierra Nevada Corporation’s Dream 
Chaser left the ground at Edwards Air Force
Base on Wednesday but the real testing is just
about to begin, more than 35 years after
the idea for a small, reusable spacecraft 
was given form by the Soviet Union.  
According to Wired, the 30-foot-long “space 
utility vehicle” was hoisted to 12,500 feet by 
a Chinook helicopter and then lowered back to the ground after 
retracting and putting down its gear. If Sierra Nevada has its way, the 
Dream Chaser will be able to launch to space with up to 12,125 pounds 
of cargo, including up to seven 
passengers, and return to land on any runway at least 10,000 feet long.
Wednesday was about checking the aerodynamics of the shuttle-shaped 
craft after decades of study, testing and, ultimately, storage by NASA. 
The Dream Chaser is derivative of the HL-20, a NASA design copied 
from the Russian BOR-4, which an Australian reconnaissance aircraft 
snapped a picture of in 1982. After extensive modeling and testing, the 
NASA prototype never made it to prime time but Sierra Nevada found 
it about 15 years ago and lifted it off the ground for the first time 
Wednesday. There will be one more helicopter hoist and recovery and 
then the space plane will be released (unmanned) for a landing. If it 
all works out, copies of the craft will be good for 15 trips to space, 
the first of which is planned for the International Space Station in 2020.
