The company announced Nov. 2 the completion of the first Dream Chaser, named Tenacity, at its facility in Louisville, Colorado. The vehicle will be shipped in the “coming weeks” to NASA’s Neil A. Armstrong Test Facility, the former Plum Brook Facility, in Ohio for environmental testing.

Sierra Space has not disclosed a target launch date for that first Dream Chaser mission, but Shields said that mission is currently planned for launch “some time in March.” That date will depend not only on the readiness of Dream Chaser itself but also the Vulcan launch vehicle. The launch will be the second flight of Vulcan, after an inaugural launch in late December of Astrobotic’s Peregrine lunar lander.
