History’s Moment of Truth
The next five years will determine, for good or ill, the future of U.S. manned space exploration for decades to come. More significant, a confluence of forces will accelerate that process.
Several of these forces rely on the decisions of Michael Griffin, NASA’s administrator. Just as crucial will be the actions of Congress and the public, and the success or failure of several private entrepreneurs, including a former programmer who is trying to rebuild the American rocket industry single-handed.
Consider first the decisions of Griffin. He faces a serious problem trying to complete and supply the International Space Station. Because his predecessor, Sean O’Keefe, chose to rely solely on the space shuttle to ferry supplies, crew and new construction modules to the station, Griffin remains entirely dependent on the Russians, because the trio of remaining shuttles was grounded after the Columbia accident in 2003.
Worse, unless Griffin can get a shuttle replacement designed and built by 2010, he will have no way to ferry supplies or crew to ISS after that, if the shuttle is retired that year as planned.

Signs of a Renaissance
There may be many problems apparent at NASA and among the U.S. aerospace giants these days, but there also are signs that space exploration is about to undergo a renaissance, with an explosion of creativity unseen in decades.
To explain this conclusion will require telling a personal anecdote, which begins in the mid-1980s.

A Shrinking, Timid Industry
The May 2 announcement that Boeing and Lockheed Martin are forming a joint venture to build and launch rockets for the U.S. government is another sign the established sector of the American rocket industry continues to shrink and stagnate.
This situation is especially critical because the National Aeronautics and Space Administration is looking to that industry to build its shuttle replacement. Unless other companies step forward and offer competitive services — and NASA is willing to hire them — the lack of flexibility, efficiency and innovation in the industry’s establishment base will make successful completion of the crew exploration vehicle difficult, if not impossible.
The non-competitive nature of the American aerospace industry was evident last fall when almost all of the major aerospace companies decided to team up to bid on the CEV rather than compete against each other.

The New Colonial Movement
Last week’s successful launch by India of two satellites was clear evidence international competition to explore the empty reaches of space is beginning to heat up.
The swelling number of countries both willing and able to explore outer space also suggests the United States’ past domination is no guarantee of future mastery.
India – possibly the most underrated spacefaring nation of all – best epitomizes this new international space race.
Most of the recent publicity about India’s space effort has centered on its plan to launch an unmanned probe to the moon by 2007.
