The super-slim, 100m-tall launcher is a demonstrator for the vehicle Nasa
plans to use in the next decade to take its new astronaut crewship into
orbit.
The Ares I-X is expected to make an unmanned, two-minute flight at the end
of the month to check out basic design concepts and gather engineering data.
However, the project's long-term future is uncertain and could conceivably
be cancelled in the coming months.
