NASA and shuttle booster-maker Alliant Techsystems are expected to sign an agreement today to work on a new commercial rocket capable of launching astronauts to the International Space Station.
NASA would work alongside ATK and a European company developing the Liberty rocket, potentially speeding the post-shuttle era availability of commercial crew transportation systems.
NASA and ATK will hold a news briefing at Kennedy Space Center at 3 p.m. today. The European company providing Liberty's second-stage engine also will take part.
You can watch the briefing here in The Flame Trench. Click the NASA TV box on the right to launch over NASA TV viewer and live coverage.
