What do you think will happen to the future of space exploration? Will it increase or decrease or plateau, or change in some other way?
In the short run, there will be little change overall. Human space flight missions will continue to the International Space Station, using Russian Soyuz spacecraft for transportation. In the long run — moving beyond ISS or missions to the Moon or Mars — the direction and pace of space exploration depends almost entirely on developments in the relevant technologies, particularly those related to launches.
Do you think privatization of space exploration is a good idea?
Most of the movement toward privatization — which has actually been under way since the Reagan Administration — I have found to be, on the whole, a positive development. Unfortunately, there have also been cases — the most notable being NASA’s decision to contract out shuttle maintenance — where the results have been anything but positive. In any event, privatization is clearly the trend of the future.
One of the great success stories in the development of the “space market” has been the commercial launch sector. In 1981, when the first privately developed rocket was launched, everything sent into space up to that point was the work of a government. By 2000, the commercial launch industry, made up of dozens of firms from almost as many countries, had become a billion-dollar business. Now, everything sent into space, with the partial exception of the shuttle, is launched by a private company. More firms, including a number interested in offering “space tourism,” are expected to join the effort in years to come.
Just how important is it that we “reach for the stars” — especially when the economy is in such dire straits?
Speaking of the economy, one small advantage a traditional, government-run space program has over the privatized approach is that the former is relatively more recession-proof.
With respect to “reaching for the stars,” it is very important that we, as a country, have a clear and consistent set of priorities. In general, I think a great nation should devote some of its resources toward the “lofty and ambitious” — which need not be as gargantuan as the Apollo program. On the other hand, I think “greatness” also means acknowledging and recognizing those occasions — hopefully few in number and short in duration — where the immediate needs of citizens requires the postponing of these loftier pursuits.
