James Cameron on exploration:

Space is a vacuum. There is, by definition, nothing there. When we talk about exploring space, we really mean exploring the objects careening around in space - planets, moons, the occasional comet. So space is a hurdle, an ocean that must be crossed to reach a destination. Unfortunately, for three-quarters of the space age it has been treated as a destination in and of itself.

The last time humans crossed space to a destination was the Apollo 17 mission in 1972. In the 32 years since, no man has seen, with his own eyes, Earth as that beautiful, solitary blue sphere, and - reality check - no woman has ever seen it at all. We've been only to low Earth orbit since 1972, and from that altitude of 220 miles, looking at the 7,900-mile-diameter Earth is like peering at a basketball with your cheek pressed against it. Yes, you'll see curvature, but you're not seeing the whole thing. We've spent 32 years "exploring space" in low Earth orbit. Exploring nothing. To stay in orbit you have to go 17,000 mph, or Mach 25. So we've spent three decades going nowhere fast.

Thank you, I was despairing of finding sufficient slack for this lazy afternoon. Your efforts will not go unrewarded, young Skywalker.

I often quote: "Man has not walked on the moon in my lifetime".

And unlike the rest of the LJ crowd, I'm 30.

It's depressing (in more than one way...)

At most you're going to see half.

You'll never see half. You'd have to be infinitely far away.

So is he suggesting that we just blast off in the void never to return? Doesn't like like much fun or much use if you can't come back with anything.

Huh? There've been several un-manned missions, which, arguably, are just as much "exploration" as manned missions.

Problems

(Link)

The problem with human space exploration is that people are very fragile. A robot will happily subside on a small nuke plant for years and collect lots of data, while humans require an immense supply-train for even short trips.

It is much, much easier to send a robot up with no need for things like "food" which take up a lot of room.

This is true, however, speaking as someone who really digs robots (esp. robot masters) I have to say that robots are not A) clever or B) all that interesting. The point (my point, and that of the article) is that sending people to other places is just a fundamentally different exercise entirely than just knowing about other places. This drive to explore is something quintessentially human (or, at least, simian) and camcorders-with-wheels just don't scratch that itch.

You can argue the economics or efficiency of it until you're blue, but the the simple fact remains that something that makes us us doesn't believe that it's real unless we've gone there. That's what makes it count.

And, economically speaking, that's what gets it funding. Because motorized camcorders just aren't that interesting. Nobody except hardcore geeks give a shit. You send a robot, it's an appliance. You send a person, it's a hero. That's all the difference in the world.

Since when was James Cameron allowed to snark at NASA for a damn thing? He's used piles of cash and almost three decades, just like NASA, but at least NASA can throw something into space. Cameron can't even make a decent movie.

snarking: nasa :: fish : barrel

Oh, come on. Well first, just because you don't like his movies doesn't mean he's wrong. But besides that: I thought Titanic was mediocre, but with the exception of the clearly-to-pay-the-bills Rambo 2*, I've enjoyed everything he's written/directed.

* I have not seen "Piranha 2: The Spawning".

Wait, did he write this before or after last week's maiden voyage of the Space Elevator Ribbon Robot? If that isn't "exploring space" enough for him, then maybe NASA should just put its foot down and stop trying. I think he's just refusing to be impressed.

Speaking of vacuums...

Heyo. I wrote a shortshort story about something similar a while back (I'm the robodump guy, btw).

In general, I'm a huge fan of space exploration. But I really have a problem with how NASA is spent its assloads of cash.

How many times can you send mice and chickpea seeds into orbit and still legitimately claim that you're doing "important research?" They habitually tout the goals of impressive new alloys and space-manufactured wonder drugs, but they've said that for decades. What have they honestly learned with all that fiddling around?

How many times do we have to have video teleconferences from space to kindergarten classrooms filled with kids asking over and over what it's like in space? Sure, it's great to get kids interested in exploration, but it's ultimately unimpressive to them when they realize we're not accomplishing anything up there.

NASA is squandering its resource doing basically nothing but PR to get it more budget so it can do more PR. They're chasing their tails.

And then there's this insanity with sending people to Mars. We continue to barely have the technology to send people to the moon, let alone any kind of extended mission anywhere.

We're trying to run before we can walk. We really really need to plow said assloads of cash into terrestrial research, research in materials and propulsion and all the touchy details behind making it feasible to safely get anywhere interesting.

Or, instead, we can anxiously wait for our next space video teleconference. I hear the astronaut's going to do something entertaining with eating floating food.

Whether we have an instinctual drive to do it or not, it seems pointless to explore places we don't want to go. How about spending most of it on the Terrestrial Planet Finder until we have a short list of a dozen or so places and then work on generation starships?

Since you linked back to this… 17,000 mph in space is not Mach 5, dammit. It’s not Mach anything.

"no woman has ever seen it at all"?

(Link)

is he in some 1950s timewarp or something. lots of women have "seen it." hell they've built it, rocked it, commanded it. more than even this link gives credit to. so f off James.

No woman has ever been past LEO, and no man has since 1972. He's talking about the view from far enough away that you can see the whole sphere.

I'll settle for some freeze dried ice cream and some brand new desktop images (in assorted trendy "colors") any day:

Would be cool to animate those over the past X images, kinda like the weather radar on the evening news.
