Dream Chaser space plane passes flight test

The private Dream Chaser space plane took to the skies Tuesday, kicking off a flight-test program that will vet the vehicle’s ability to carry astronauts to and from low-Earth orbit.

The Dream Chaser, which is built by aerospace firm Sierra Nevada Corp. (SNC), did not fly under its own power during the test. Instead it was held aloft the entire time by an Erickson Air-Crane heavy-lift helicopter, which hauled the space plane through the skies near Denver to verify its aerodynamic flight performance.

Still, the so-called captive-carry test marks an important step forward in the Dream Chaser’s progress, company officials said.

“The successful captive-carry flight test of the Dream Chaser full-scale flight vehicle marks the beginning of SNC’s flight test program, a program that could culminate in crewed missions to the International Space Station for NASA,” said former astronaut Steve Lindsey, head of the space plane’s flight operations at Sierra Nevada, in a statement.

Developing private astronaut taxis Sierra Nevada is one of four spaceship-building companies to receive funding from NASA’s Commercial Crew Development (CCDev) program, which is encouraging private American vehicles to fill the astronaut-carrying void left by the retirement of the space shuttle fleet last year.

Sierra Nevada got more than $100 million in two rounds of CCDev funding over the past two years, which it’s using to develop the Dream Chaser. Tuesday’s captive-carry test allows the company to check off another milestone stipulated in the second round, known as CCDev-2.

“This is a very positive success for the Dream Chaser team and their innovative approach,” said Ed Mango, NASA’s Commercial Crew Program manager. “I applaud and encourage the designers and engineers to continue their efforts in meeting the objectives of the rest of their CCDev-2 milestones.”

Data from the captive-carry test will be used to evaluate and prove hardware, facilities and ground operations in preparation for approach and landing tests, during which the Dream Chaser will be carried into the skies and then dropped. The first of those test flights is planned for later this year, officials said.
