Why Does the US Have a Civil Space Program?
BDew writes "The Presidents of the National Academy of Science and the National Academy of Engineering have commissioned a study on the Rationale and Goals of the US Civil Space Program. In short, the Academies are asking why the nation has a civil space program (including human, robotic, commercial, and personal spaceflight). The study is intended to provide a strategic framework for the nation's activities in space that can provide consistent guidance in an increasingly interconnected world. The members of the study committee are interested in the views (positive or negative) of the general public, particularly those people with a scientific and/or technological interest."
That's why I'm very leery of scaling back NASA. The moon shot was propaganda, partially, but it also unleashed a ton of new technologies and trained a generation of engineers. Of course, we could go along with the privatizing globalists, but you see how well that's working?
We may or may not find a role for men in space this generation, but space travel and investigation is absolutely fundamental for our survival as a species. And no corporation will EVER do what needs to be done, because it's not profitable except indirectly.
Because it's polite.
An uncivil space wouldn't get much in the way of positive press.
And fund our research instead.
That would have been my first guess, given that there's a very vocal cadre who look for every opportunity to quash manned spaceflight, but TFA doesn't seem slanted in that direction. Could just be lip service, but I'm hoping it is what it says it is: A study to re-examine what we want to do, cross-index that with what we think we can do, and use that to create some concrete plans.
Then again, if the Obama administration turns NASA into the US Space Force, civil space pursuits at the national level may dry up entirely, leaving only military and private space efforts. Not sure I like the sound of that.
The reason for a civil space program is pragmatic. The military and government is concerned with goals that are separate and distinct from civilian interests. But what are those interests?
The military is concerned with control, management, and protection of national assets. Communications, surveillance, and counter-terrorism are primary goals. Towards this end, the military produces missiles and delivery systems capable of providing this. But the military has no need to explore space, or advance scientific research beyond this.
There is no military or security reason to put someone on the moon, or map out the surface of other celestial bodies. However our understanding of these can advance civilian interest. For example, the helium-3 surface deposits on the moon could provide a energy source far greater than that of fission or conventional power generation. Exploration of the martian environment could provide clues to the formation of our own planet and answer a question long-sought after by both scientists, philosophers, and theologians -- where do we come from? How did we become what we are today? By deploying powerful sensing technology into space we can peer deeper into the universe and unlock many secrets, providing advances in physics, metallurgy, and many other fields. Putting people into space allows for research in microgravity and zero gravity environments. Certain molecular structures only form in the absence of a strong gravitational field. It could provide for advances in building materials, or allow for the development of quantum devices that may not be possible to produce terrestrially (or be prohibitively expensive) en masse. Frankly, there is considerable research that needs to be done.
Military and scientific needs can sometimes be at cross purposes. The creation of a fusion power generator with a net positive output would be a major advancement for any country. Further exploration of the moon may in fact provide this as there are isotopes found there that are very amiable to this goal, much more so than any terrestrial source. However, such a powerful energy source could be used to create star-wars styled weapons, making land-based particle accelerators a reality, or other advanced weapons systems that simply aren't practical to deploy today. Localized atmospheric heating, strong RF fields to provide an ionization layer above a target, etc., all become possible with a large energy source. Because of this, the military would likely move to be an obstacle in such research because it threatens the balance of power. Perhaps it already has.
The military and civilian programs should work in tandem when possible to reduce overall costs, but should also be allowed to initiate their own programs independently of each other, as the need arises. To collapse the two into a single entity gives rise to questions of trust, integrity, and overall effectiveness. Ultimately, it would not be as beneficial to society as the present system is, though in the short term it would offer some economic benefit -- but at the expense of long-term economic and social gain.

The problem with 'scaling back' NASA is that it's not like a factory or a bunch of servers that you can just switch back on in 5 years with a bit of maintenance.
If you cut funding and they have to cut engineering jobs, you're going to lose talent: experience that may not return when you decide you're in another space race.
What is the real use of getting a man to Mars or another planet other thean bragging about it for the next 70 years? Somehow, some people are in favor of a manned space program. The question is, what is the tangible benifit of sending people to the moon/Mars/Jupiter/Proxima Centauri?
That's right up there next to the question "Why spend any money on space at all when we have so many problems that need solving right here on Earth?" I can't buy into either viewpoint. Manned spaceflight has its place, and I'll fight any effort to terminate it.
I feel that there is a lack of a concrete goal, something to stand behind.
Now this I can totally get behind. Goals are good, and a lack of them, or more accurately a continuous redefining of them, has crippled the US space program for decades.
Something that has a good probability of pay-off in the future. Is "finding out things about other planets" a goal that convinces people to support (manned or unmanned) spaceflight? What do we really want?
Sounds like your answers would be "No" and "Profit". The whole "pay-off" bit is a club that has been used to beat the space program repeatedly over the years. "What's in it for me? What's the return on my investment?" As with other forms of research and exploration, it's nearly always impossible to give firm answers to these questions. But experience has shown that the real answer usually is, "Far beyond expectations."
Ad astra per aspera!

"Sending people to the moon" had a lot of prerequisites. These prerequisites include:
And many, many more (see http://techtran.msfc.nasa.gov/at_home.html, http://spaceplace.jpl.nasa.gov/en/kids/spinoffs2.shtml, http://www.nasa.gov/audience/foreducators/5-8/features/F_Spinoffs_Extra.html etc.)
"Putting a man on mars" is simply an easy-to-define milestone. The real benefits are too long to lists.
As lead mechanical engineer who designed, built, and tested a lunar mining machine within the last year, I can assure you: we're working on it.
Let me just indicate that if NASA (or some other government entity) had not funded the project, the private space sector would have taken decades to begin considering funding it.
The civil space industry provides funding and support for state-of-the-art space technologies, while the private space industry - with their ROI requirements - follows behind. There is nothing wrong with this protocol. If you'd like to see more private space industry, fund NASA so that companies can justify spending money on more mature technologies.
IWARS.
People, in general, disappoint me. Politicians even more so.
That sounds like a fantastic idea for a book.
