Dream Chaser Spaceplane Nears Epic Maiden Mission with Successful Test.

Sierra Space's Dream Chaser spaceplane has powered up its systems in a key test, bringing it a step closer to its first flight. The company plans to ship the first Dream Chaser, called Tenacity, to NASA's Neil Armstrong Test Facility in Ohio for thermal vacuum tests before shipping to Cape Canaveral for final launch preparations. Dream Chaser is slated to launch on the second Vulcan mission, after a launch of an Astrobotic lunar lander that has slipped to later this summer because of launch vehicle testing issues.
