Consider NASA: Today’s extremely expensive and somewhat unsatisfying staples of US human spaceflight, the space shuttle and a space station, can be traced back forty years or so to the aftermath of the Apollo program, when President Nixon chose them as its replacements. The legacy of these choices is that no one has ventured beyond low-Earth orbit ever since.
This has far graver implications than failing to fulfill a generation’s dreams of Pan-Am moon flights and Lunar Hiltons. In the fullness of time, lack of progress in expanding humanity’s sustainable presence off-planet represents an existential threat to our species. Even staunch critics of human spaceflight must acknowledge this. It doesn’t take a rocket scientist to realize that keeping all one’s eggs in a single, vulnerable planet-sized basket is an unsound long-term investment strategy. To do so is to court extinction.
NASA administrator Charles Bolden may have had such thoughts in mind on Tuesday when he addressed the audience at the National Space Symposium. “This is a big week for the entire nation,” Bolden said, “and it’s a week where probably more people than ever before will be thinking about space. It’s an important week for all of us in the space industry and it’s a particularly important week for NASA.”
Bolden was referring to the Obama administration’s new plans for America’s space agency, which the president himself presented and defended yesterday in a speech at Kennedy Space Center in Cape Canaveral, Florida. President Obama’s 2011 budget request eliminated funding for the earlier Bush administration’s Constellation program, which aimed to build a fleet of government-run rockets for returning astronauts to the Moon in the 2020s to build a lunar base. Instead, Obama’s plan deemphasizes the Moon and pumps more money into the commercial space sector for creating rockets to replace the aging space shuttle fleet. It also seeks to spark innovation, boosting NASA funds for development of breakthrough technologies in space-based propulsion, life-support, and power generation.
