Permanent moon base planned: NASA wants to start building way station for Mars voyages near south pole by 2024
Following in the footsteps of the Space Shuttle and the International Space Station, NASA has announced it will be constructing yet another ridiculous boondoggle on the surface of the Moon.
NASA's reasons for returning humans to the Moon are baffling. For each of the reasons given, Mars is clearly the better destination.
Human Civilization - Extend human presence to the Moon to enable eventual settlement.
Human settlement beyond Earth is all well and good, eggs in one basket and all that, but Luna shouldn't be at the top of anyone's list for places in Sol System to live. It has no atmosphere, crazy radiation, and very little water. Mars has an atmosphere, less-crazy radiation, and lots of water. Mars also doesn't suffer from that
two weeks of complete darkness problem.
Yeah, yeah, I know, put the base in permanent sunlight at a pole and mine (theoretical) water in a nearby crater. That's some settlement, yup.
Scientific Knowledge - Pursue scientific activities that address fundamental questions about the history of Earth, the solar system and the universe - and about our place in them.
NASA is trying to make the
comparative planetology argument here, but it doesn't fly. Scientifically, the Moon is good for one thing: radio astronomy. We can build a huge radio telescope on the far side in a big crater using materials mined from the regolith. But that can be automated. Geology is important, yes, but robots can do that, too.
If you really care about "fundamental questions about the history of Earth, the solar system and the universe - and about our place in them," then Mars is the place to be. Mars is great for comparative planetology because it has a number of similarities to Earth - many more than Luna. Additionally, Mars may be a destination for paleontology and, perhaps,
astrobiology. The Moon can't even come close to that claim.
Exploration Preparation - Test technologies, systems, flight operations and exploration techniques to reduce the risks and increase the productivity of future missions to Mars and beyond.
This one is, I think, the most egregious. It implies a couple of things that are just plain wrong. One is that we need to use the Moon as some kind of waypoint between Earth and Mars. This is criminally stupid. Imagine gasoline cost $10,000 per gallon and you had to drive from Houston to Chicago. You wouldn't stop to rest in Seattle along the way, would you? But that is exactly what NASA expects us to do.
Space travel is expensive and it requires a lot of energy. This energy is typically expressed in terms of delta-v, the change in velocity one needs to make to get from point A to B. As Newton explained to us, things in motion tend to stay in motion, so stopping at the Moon before we head to Mars is a bad idea. It takes a lot more energy to leave Earth, land on the Moon, leave the Moon, and land on Mars than it does simply to go from Earth to Mars.
In fact,
it takes less energy to get to Mars' surface from Earth's surface than from Earth's surface to the Moon's surface. This is counterintuitive, because the Moon is closer, but distance has little to do with it. It is the gravity well that is important. And while Mars has a deeper well to descend into, it has an atmosphere: free brakes!
If you are going to test exploration techniques for Mars, you should do it in an
environment analogous to Mars. Luna ain't it.
Global Partnerships - Provide a challenging, shared and peaceful activity that unites nations in pursuit of common objectives.
Blah, blah, blah.
Too bad nobody called Russia first, because they forgot to put the Moon down as a line item in the budget. And I'm sure
China is so excited to share.
Economic Expansion - Expand Earth's economic sphere, and conduct lunar activities with benefits to life on the home planet.
Yes, perhaps we'll have cracked the fusion problem by 2024 and we'll be hunting for some
helium-3. I won't be holding my breath. If NASA is serious about economic expansion (or, really, about any of these issues), they'd crank up an Apollo-style program to build a
space elevator instead.
Public Engagement - Use a vibrant space exploration program to engage the public, encourage students and help develop the high-tech workforce that will be required to address the challenges of tomorrow.
To boldly go where we've been before, yup, that'll engage 'em. These "challenges of tomorrow" were challenges in 1960 and were solved nine years later. Since then, we've been going around in circles and they're asking for another 15 years to go back. For the money we've spent on Iraq,
even I could be living on Mars right now.
I was working on becoming an astronaut up until my sophomore year of college. I'm glad I changed direction, because I would be going nowhere very,
very fast if I hadn't.
UPDATE: The
New York Times shares my opinion in this matter.
