Mark Moody, an employee of Lockheed Martin Corp., works on preparations for a brace for the Dream Chaser mini-space shuttle designed by Sierra Nevada Corp. - one of three companies working on spacecraft to get NASA astronauts to and from the International Space Shuttle. Lockheed Martin also has two other, unrelated, projects at Michoud Assembly Facility in eastern New Orleans - a campus where thousands of people worked in the 1980s to build space shuttle fuel tanks.
