NASA's New Mission to the Moon
mattnyc99 writes "Popular Mechanics has a new, in-depth preview of NASA's Orion spacecraft, tracking the complex challenges facing the engineers of the CEV (which NASA chief Michael Griffin called 'Apollo on steroids') as America shifts its focus away from the Space Shuttle and back toward returning to the moon by 2020. After yesterday's long op-ed in the New York Times concerning NASA's about-face, Popular Mechanic's interview with Buzz Aldrin and podcast with Transterrestrial.com's Rand Simberg raise perhaps the most pressing questions here: Is it worth going back to the lunar surface? And will we actually stay there?"
NASA's mandate, overt or not, is also to help the Department of Defense fulfill its goals in space.
What for? Surely this is just another presidential exercise in sticking it to the Commies?
True, but there are other benefits. Learning how to colonize space would be a biggie in my book. Besides, if we can't go to the moon, we don't stand a chance at going to Mars, Europa, Titan, or possibly beyond our solar system. The moon is the first step.
There is no "I disagree" mod for a reason. Flamebait, Troll, and Overrated are not substitutes.
As the folks at Goddard expained it during the Moon Math student competition, "When you go camping, isn't it a good idea to try setting up the campsite in your backyard first, 600 inches away, so you can try out everything, or run back in the house if you forgot your flashlight, make sure you remember to bring everything, and *THEN* go camping for real to somewhere 600 miles away?"
That's a largely non-obvious reason for using the same basic vehicle for both mission sets.
"Win treats sysadmins better than users. Mac treats users better than sysadmins. Linux treats everyone like sysadmins."
The moon is the first step.
Why? Colonizing the moon is a drastically different undertaking from colonizing Mars. The moon is essentially a vacuum. It's cold. It has no useful resources to speak of (and no, He3 won't be useful any time soon). 1/6th Earth's gravity. And it's fairly close.
Meanwhile, Mars has water. And abundance of minerals. A thin atmosphere containing useful gases. A surface temperature that actually breaks the freezing point occasionally. Double the gravity of the moon. And it's so far away that getting there has proved to be a surprisingly difficult undertaking.
Honestly, the idea that colonization of the Moon will tell use anything useful about colonizing Mars is, frankly, silly. The methods that would be used for the two projects are *completely* different. Meanwhile, we can't even build a self-contained biosphere on *Earth*! Maybe we should try tackling that drastically simpler task before we start planning Moon bases.
