Apollo Veteran: Skip Asteroid, Go To the Moon
astroengine writes "It's 40 years to the day that the final mission to the moon launched. Discovery News speaks with Apollo 17 astronaut and geologist Harrison 'Jack' Schmitt about where he thinks the Earth's only satellite came from and why he thinks a NASA manned asteroid mission is a mistake. 'I think an asteroid is a diversion,' said Schmitt. 'If the ultimate goal is to get to Mars, you have a satellite only three days away that has a great deal of science as well as resources. The science of the moon has just been scratched. We've hardly explored the moon.'"
The National Research Council came out with a report a few days ago which found that the inability for the U.S. to find a consensus on where to go is damaging its ability to get there. Bill Nye spoke about the issue, saying, "I believe, as a country, we want to move NASA from [being] an engineering organization to a science organization, and this is going to take years, decades. Now, through investment, we have companies emerging that are exploring space on their own and will ultimately lower the cost of access to low-Earth orbit, which will free up NASA to go to these new and exciting places."
out of the defense budget, and go do both. The US is already the dominate military power on the planet, bar none, so I am sure they could trim the military budget by a tiny percentage without anyone who doesn't wear a brass hat noticing. Whats the saying? "A billion here, a billion there and pretty soon your talking real money?"
Its nice to think that private enterprise will provide the means to get there (for whatever values of "there") but although its happening, its not happening overnight. NASA needs to continue doing it all themselves until business is established in orbit - otherwise we waste a few decades waiting for it. As well, think of all the scientific discoveries we might make during this moon mission series. The last one turned out pretty well didn't it?

The ugly reality is that our society has shifted toward one focused on inward spending and care, not outward focus and exploration. This was inevitable with the radical demographics change that has happened in the last 15 years as the Baby Boomers, who are something like 1:1.5 with Generation X and Millennial put together got to the point where they need to start retiring. Aging societies become inward focused, with the focus being on domestic spending, not "young activities" like exploring new frontiers at tax payers expenses.
An elderly relative of mine was complaining about the cost overruns on the F35, and I pointed out to them that the whole federal R&D budget across all departments was likely less than the $112B in Medicare fraud that the OIG for Medicare uncovered about six months to a year ago. Many of those overruns aren't even "fraud" but rather are caused by things like different government "stakeholders" coming in at the 11th hour to add new requirements on projects (IIRC, the F35 was almost done, and the USMC nearly killed it by demanding that they get their VTOL piece come hell or high water even though it was ready for NATO naval forces).
It was disheartening for them to hear the plain and simple truth: we are an aging society that is cannibalizing its stored wealth to lavish retirement and health care benefits on the older citizens. It is absolutely true that we don't have money anymore for foreign wars and big military adventures. It's also true that at present budget projections we won't have a budget for NASA, the NSF, federal law enforcement, the US highway system, education subsidies and anything else that doesn't revolve around pure entitlement spending for the massive waves of retirees hitting and about to hit the system.
What could we learn about an asteroid from sending a person there that we wouldn't learn from sending a modern robot there? What could we learn from the moon or mars today that we couldn't learn from a robot?
Quite a lot actually. Now, part of that is simply the reality that a manned mission is going to be orders of magnitude larger and more complex, just by definition.
For instance, sample return is basically built into a manned mission. If you add a sample return objective to a robotic mission the cost numbers are suddenly much closer (still not close exactly, but closer). The rate of exploration is also much, much higher for a manned mission. The Mars rovers, for example, were designed to move just 600 meters over their lifespan. They've obviously exceeded that, Opportunity has driven 20km so far after all. Apollo 17, on the other hand, covered that distance in a matter of days. A prolonged human presence would allow us to explore a larger area in much more detail than would otherwise be possible. Not to mention the possibility of bringing a real chemistry lab along for the rid (as opposed to the 'lab on a single camera' setups that robotic missions use).
Yes, a lot of those advantages would disappear if you spent the same on a robotic mission as you did on a manned one. But you also have to remember the human factor. Humans can perform repairs, investigate problems, spot things in the terrain, cover more ground, look at things from different angles (in a matter of seconds), etc, etc. Designing a robot that can do everything that a human can do as well as a human can do it, even ignoring the light speed communication issues, would probably be more expensive than just sending the human in the first place.

Do not pass the LaGrange point, do not collect $2bn.
If the only way you can accept an assertion is by faith, then you are conceding that it can't be taken on its own merits
You know, your argument would be more persuasive if you knew the difference between a million and a billion.
By 2020, and it's a private venture.

Of course, Curiousity is actually doing something other than just moving in a circle around the Earth.
Would the kids be more interested in Curiousity than they would be in six men on Mars?
