Panel Finds Current Spaceflight Strategy Unworkable
Friday, August 14, 2009
NASA doesn't have nearly enough money to meet its goal of putting astronauts back on the moon by 2020 -- and it may be the wrong place to go anyway. That's one of the harsh messages emerging from a sweeping review of NASA's human spaceflight program.
Although it is just an advisory panel, the Human Space Flight Plans Committee could turn the entire space program upside down. Appointed by President Obama and headed by retired aerospace executive Norman Augustine, the 10-person panel has held a series of marathon meetings in recent weeks to try to Velcro together some kind of plausible strategy for NASA. The agency's trajectory over the next two decades, as well as the fate of thousands of civil servants and private contractors, could be affected by the group's report, due at the end of this month.
The committee members will meet with administration officials Friday and are likely to say that under current funding, there's no realistic way to get Americans back on the moon by 2020, which has been the goal since President George W. Bush signed off on the "Vision for Space Exploration" in 2004. The current NASA plan makes a moon landing in 2020 possible under the budget only if the agency de-orbits the international space station -- crashing it into the South Pacific -- in 2016.
Moreover, the current strategy involves retiring the space shuttle in 2010 and replacing it with the new Ares I rocket and the Orion crew capsule, which NASA hopes would be ready to take astronauts to low Earth orbit in 2016. During the long gap in NASA's human spaceflight ability, American astronauts would have to hitch rides into space on Russian rockets. The awkward plan has been seen as a budgetary necessity, with shuttle program money flowing into the new Constellation program that features the new space hardware that could eventually put astronauts on the lunar surface.
The committee has chewed over a basic paradox in the plan, which is that, even if everything went smoothly, the new rocket would not be able to get astronauts to low Earth orbit until just about the time that the space station would be fireballing its way back to Earth.
Although the station has never been terribly popular with scientists, its $100 billion price tag and role in international aerospace cooperation makes its early demise politically unpalatable. The Augustine panel assumes the station's life will be extended to 2020. But under that budgetary scenario, according to the panel's just-completed analysis, the current NASA budget would not permit the launch of a new heavy-boost moon rocket, the Ares V, until 2028 -- even without any funding for key lunar-base components.
"If you're willing to wait until 2028, you've got a heavy-lift vehicle, but you've got nothing to lift," said committee member Sally Ride, the former astronaut, in Washington on Wednesday at the final public meeting of the committee. "You cannot do this program on this budget."
Committee member Jeff Greason, an aerospace executive, derided the NASA strategy, noting that the fixed costs of the current Constellation program are sure to bust the budget in the decades ahead: "If Santa Claus brought us this system tomorrow, fully developed, and the budget didn't change, our next action would have to be to cancel it."
NASA spokesman David Steitz said it would be premature for the agency to comment on the committee's work.
John Logsdon, the former director of the Space Policy Institute at George Washington University, observed the panel's session Wednesday and said NASA faces a problem that has been years in the making.
"This is a heritage of one of the many failed promises of the Bush administration -- to set out a very good policy and then not provide the resources that come anywhere near funding it," Logsdon said.
The panel will give the administration a menu of options that includes some that require a boost in funding for human spaceflight, which currently costs a little less than $10 billion a year, including the shuttle, the station and the Constellation program. Those options will include variations of a lunar program -- the committee appears to prefer to see astronauts making sorties to various locations on the moon rather than concentrating on a single outpost at the moon's pole, which is the current plan.
