Funding "Exciting" Space Research

More

2375613159_c3584e055d_o.jpgIt's not easy being a NASA researcher. You can spend years of your professional career working on a particular project, only to have it abruptly cancelled because a new Administration takes office or ... well, the country just shifts its sights and priorities. And your particular project no longer fits on the list. It's happened so many times over the agency's 50-year history that it's almost predictable. And the reasons for those shifts are numerous, and sometimes complex. 


But as a piece in this week's Science Times noted, NASA is coming to yet another research fork in the road. I saw this one coming back in January 2004, when President George W. Bush announced we were going to go back to the Moon, and on to Mars ... and then didn't actually allocate any extra money for the effort. NASA slashed other research budgets and drastically shifted program priorities to comply with the new directive, and began developing the basic technology the first steps of the effort would require. 

It was clear to me, even at the beginning, that the program was more of a nice PR moment than any real commitment or serious priority. Money talks, and the money wasn't allocated. What's more, a new President is now in power, and he's indicating that more budget cuts in the program may be in the offing. So after decimating science and aeronautical programs to fund Moon and Mars-oriented technology development, the agency finds itself, once again, facing the possibility of having to tell its researchers, "never mind." It's "a hell of a way to run an airline," as the saying goes. 

But in the article's discussion of possible funding and program options, one particular comment caught my attention. One cost-saving option on the table would be to bypass a Moon landing, and concentrate research efforts on a series of long-duration space flights (the type that a Mars mission would require). But Gabrielle Giffords, chairwoman of the House subcommittee on space and aeronautics, reportedly commented that she didn't find that option particularly exciting, and didn't imagine her constituents would, either. 

My first thought was, "why does space research have to be exciting?" Do we require cancer research to be dramatic material for prime-time viewing? Of course not. All we care about is results. But the human space flight program, some argue, exists primarily not for its scientific value, but for its inspirational value. In which case, I guess its "excitement" factor becomes more relevant. 

On the other hand, it's not entirely clear what Giffords meant by her comments. Perhaps she wasn't arguing that the space program ought to be a lightweight version of "exciting," as in "ready-for-prime-time photo ops," but exciting in the sense of its potential impact. And if that's the case, then I agree with her. Research, in cancer, technology, or space, should hold exciting potential for advancement or discovery. Even if the "big bang" advancement lies some distance in the future. 

But what constitutes exciting? To some people, developing the technology to allow humans to live for extended periods of time on another planetary body is incredibly exciting. "So far, we haven't been space explorers. We've been space backpackers, taking everything we need  to survive with us," says K.R. Sridhar, a scientist and engineer who developed oxygen generators for NASA's Mars research program, only to have the project cancelled just before launch. Maybe living on Mars doesn't sound like a particularly fun or worthwhile experience. But developing the technology to allow humans to live beyond planet Earth ... that's kind of exciting. And perhaps even important, if we want our species to have the ability to survive cosmic disasters. 

On the other hand, there are lots of other exciting research possibilities in space that don't involve the cost of a human space flight effort. The Kepler telescope, launched in March, is designed to search out planetary bodies orbiting distant suns at the right distance (ergo temperature) to allow water, and life as we know it, to exist. The telescope uses a sophisticated photometer to measure dips in brightness in the suns, indicating the passage of planetary bodies in front of them. By the size and frequency of the shadows, scientists will be able to determine the planets' orbital distance from the suns. 

What does that do for us? As they've gained knowledge about just how massive the universe and numerous its galaxies are, scientists have become more confident that there must be life elsewhere. If Kepler can narrow the search down to some candidates with at least the first prerequisite for life (distance from a medium-sized sun), they might be able to do further scans, with other instruments and telescopes, to determine if elements like ozone, CO2, or oxygen exist in those distant atmospheres. What then? Kepler's principal investigator, a scientist named Bill Borucki, who championed the idea for decades before finally convincing his peers to support the research, said in a recent interview with Newsweek that eventually, we might launch "a probe that can travel near the speed of light and gets there, shows us pictures, listen to their radio stations and television stations, and gives us a much better understanding of this new planet."

If that's not exciting, I don't know what is. 

NASA's researchers have struggled for years with how to keep the public interested in what they do, because doing anything in space is expensive. NASA, and its predecessor, the National Advisory Committee for Aeronautics (NACA) were formed to tackle problems and explorations that don't have a clear commercial benefit, and so aren't likely to be pursued by commercial companies, or are too risky to be pursued by commercial companies. And even with the advent of more commercial space companies, that difference in goals and risk-tolerance still exists. But since the public is footing NASA's bill, there's additional pressure for its work to appeal to a voting public with many more near-term concerns than how to save the species if an asteroid threatens or the sun explodes. 

So although there's worth in any new knowledge or technology ... with limited resources, choices have to be made. Some already question the value of the International Space Station which, in the Moon/Mars plan currently on the books, would be dismantled only five years after its completion to free up funds for the next effort. A lot of other research was sacrificed to fund the Space Station. We surely don't want to keep doing that, if we aren't really excited about the results we get in the end. 

We have a lot invested in the human space flight program, and the impact of dismantling it would be huge. Jobs, infrastructure, and knowledge now in place to pick up any new project would disappear--or at least scatter. Which means rebuilding it later, if we wanted to do that, would be an onerous task.(Dismantling it would also be politically tough, because of the jobs and local economic impact involved.) But maybe, radical as it might seem, "in the neighborhood" human space flight is something NASA can now turn over to the commercial sector. And maybe, especially in a time of tight budgets, NASA's money would be better used funding many smaller but very exciting projects like Kepler, and doing the risky work of figuring out how to explore the universe beyond our eight small planets. Rockets, after all, don't need humans on them to test new technology in ion or other propulsion systems, and even habitat technology like oxygen generators.

Then, if Kepler's descendants one day find a planet that looks suspiciously like a big blue marble, and has some interesting sounds bouncing across its ionosphere, we might have a reason to put humans back on the top of research rockets. A really, really, exciting one.
