NASA Moves Forward on Manned Spaceflight

NASA's plans for human spaceflight got a shot in the arm this week.  A test flight of the Orion Multi-Purpose Crew Vehicle has been proposed for 2014.  Exploration Flight Test 1, or EFT-1, will launch an unmanned Orion into Earth orbit to test critical systems and re-entry at a high velocity.  NASA had previously stated that an unmanned Orion test flight could occur in 2017, so for once in the history of spacecraft development things are actually ahead of schedule.

The Orion capsule is being developed by Lockheed Martin, and it appears to be NASA's choice for the next phase of human exploration of the solar system.  Originally designed as part of the now defunct Constellation program, Orion got a second chance at life, and now looks like it may serve a dual role as a deep space exploration vehicle, as well as possibly doing some ISS taxi/escape boat service.

Eventually, Orion will ride atop NASA's planned Space Launch System (SLS) rocket.  However, as the SLS probably won't be ready for a test flight in 2014, EFT-1 will take place using an existing commercial heavy-lift rocket.  While no existing American made commercial rockets are man-rated, a Falcon-9 or a Delta-IV could launch an unmanned Orion capsule to the high orbit required of the test flight.

Speaking of SLS, NASA is making headway in that department as well.  This week NASA successfully tested the powerful J-2X engine at Stennis Space Center in Mississippi.  The J-2X will be the engine on the second stage of the SLS rocket.  When complete, the SLS will be the most powerful rocket ever built, with the ability to lift over 130 tons into orbit.  It is this massive rocket that will one day be lifting the Orion capsule out of Earth's orbit entirely, on trips to the Moon, an asteroid, or Mars.
