Lockheed Martin has tested a prototype reusable launch system by flying a sub-scale flight demonstrator from the site of New Mexico's proposed Spaceport America.

The successful test flight of the proprietary vehicle took place in December and was only recently disclosed. A company official said Lockheed Martin is planning more tests using ever-larger vehicles.

Lockheed Martin Space Systems teamed with launch provider UP Aerospace of Highlands Ranch, Colo., Dec. 19 to conduct a small demonstration launch at Spaceport America in southern New Mexico to evaluate proprietary technology the company currently has under development.
