As for Mars, more nonsense. Mars is just too far away. And how do you get there without the stepping stones of Ares and Orion? If we can't afford an Ares rocket to get us into orbit and to the moon, how long will it take to develop a revolutionary new propulsion system that will take us not a quarter-million miles but 35 million miles?
To say nothing of the effects of long-term weightlessness, of long-term cosmic ray exposure, and of the intolerable risk to astronaut safety involved in any Mars trip -- six months of contingencies versus three days for a moon trip.
Of course, the whole Mars project as substitute for the moon is simply a ruse. It's like the classic bait-and-switch for high-tech military spending: Kill the doable in the name of some distant sophisticated alternative, which either never gets developed or is simply killed later in the name of yet another, even more sophisticated alternative of the further future. A classic example is the B-1 bomber, which was canceled in the 1970s in favor of the over-the-horizon B-2 stealth bomber, which was then killed in the 1990s after a production run of only 21 (instead of 132) in the name of post-Cold War obsolescence.
Moreover, there is the question of seriousness. When John F. Kennedy pledged to go to the moon, he meant it. He had an intense personal commitment to the enterprise. He delivered speeches remembered to this day. He dedicated astronomical sums to make it happen.
At the peak of the Apollo program, NASA was consuming almost 4 percent of the federal budget, which in terms of the 2011 budget is about $150 billion. Today the manned space program will die for want of $3 billion a year -- 1/300th of last year's stimulus package with its endless make-work projects that will leave not a trace on the national consciousness.
As for President Obama's commitment to beyond-lunar space: Has he given a single speech, devoted an iota of political capital to it?
Obama's NASA budget perfectly captures the difference in spirit between Kennedy's liberalism and Obama's. Kennedy's was an expansive, bold, outward-looking summons. Obama's is a constricted inward-looking call to retreat.
Fifty years ago, Kennedy opened the New Frontier. Obama has just shut it.
