Video: Onboard camera captures Orion capsule return to Earth

Employees and flight hardware for NASA’s Space Launch System and Orion spaceship were mostly spared after a strong tornado struck the agency’s Michoud plant in New Orleans on Tuesday, but crews planned to begin repairs immediately to plug holes in buildings housing parts and tools to build the new mega-rocket.

The pace of the European Space Agency’s development of a power and propulsion module for NASA’s Orion crew capsule will likely determine when an unpiloted test flight of the spaceship and its heavy-lift rocket will take off, NASA officials said last week.

A critical test firing Saturday of the four main engines powering the first stage of NASA’s gargantuan Space Launch System moon rocket is the final major hurdle before the fully assembled booster’s costly, oft-delayed launch late this year on an unpiloted test flight.
