I believe that is the esteemed Hank Johnson, representative from Georgia. He replaced the crazy that was Cynthia McKinney. I guess they like them dumb, but not crazy.

Gyrfalcon: ...or end Earth as we know it when we accidentally lasso some kind of sleeping beast that's been sleeping in orbit for thousands of millennia and thaw it out, thus causing it to eat everything alive on the surface of our planet.


Nah.  A ragtag group of socially awkward yet oddly likable kids, on bicycles, will save the planet with a little help from the eccentric old ex-professor who has crazy white hair and talks to himself a lot.  He forgets to tie his shoes but is somehow able to build a manned spacecraft in his backyard, which, amazingly, the kids are able to operate.  The professor is also the only adult in the world who believes the kids, because, of course, every adult in the world is stubbornly oblivious to the impending doom which is plainly obvious to everyone under the age of 12.

Haven't you seen any Disney movie made since 1980?

Biser: Loren: And where does the Δv come from to move the asteroid?

He said they were going to use an Orion capsule to get it.  The Chinese and Russians would go bat shiat insane if they tried an Orion drive.   In short, it's a fusion bomb going off behind a solid shield. Lather, rinse and repeat.  It could be attempted since small bombs of 200 kt size only weigh 325 pounds (W-89 warhead).

Technically possible, politically impossible.


Orion capsule != Orion drive.

Furthermore, blasting one like that isn't exactly what the scientists want, nor would the astronauts like tramping around ground zero.

The Snow Dog: Why don't we just go study the one at Sun-Earth L4, 2010 TK7? Now just deposit that into my account and get to work. (I know 300m is bigger than you're looking for and you aren't going to want to tow it towards Earth, but I'll bet there are a couple of smaller ones there in the Greek camp that you could slow up a bit.)


The Δv to get there is low, the time isn't.  Astronauts eat, drink and breathe.

As I said I'm pretty sure it's not the nuke-powered Orion they're talking about:

Orion (spacecraft)

Basically it's the successor to the shuttle.

Belias: Allowing for a bit of layman's conversion, the senator is actually not too far from the truth.  For those questioning the  Δv, note that the $100 million is to find the right asteroid - one not only of the right size/composition, but who's current path is conducive to nudging into capture orbit with a reasonable thrust amount.

Holy hell, did I just defend a senator?


Bill Nelson is known to be something of space nerd; it's more than likely he either deliberately "dumbed down" the explanation or asked NASA to give him layman terms to use beforehand. Say what you will about Florida, we love those NASA folk.

Not trying to be snarky, but I really don't see a reason we need to put people on an asteroid. I think if we want to study one, this is a good candidate. But mostly what I'm saying is that the location could be a good candidate location in which to concentrate our search for a small, robotically movable one (if we just won't be happy studying one in any other fashion).

I have a doubt.

They are going to send astronauts to visit a captured asteroid. One that has a rocket engine attached to it. Does "I have the high ground" mean anything? Anybody read "The Moon Is A Harsh Mistress"? Hope the astronauts are in a good mood- but not one of those "ecstatic for the glory of Allah, I will soon see Him" kind of good moods.

Infernalist: I'm hoping this leads toward an effort to establish a human presence in the asteroid belt.   Mars is a bust, after all.  Better to head out into the solar system than head inward.

First the asteroid belt, then onto the moons of Jupiter.

Nope, I was 18 in 1980. My mindset was shaped by heroic yet tragically flawed humans landing on barren planets due to curiosity and the insatiable greed of their parent corporations, and becoming infected by some horrible yet gruesome alien monster that nevertheless is coveted by Earth due to its unstoppable killing power. Those movies never ever end well. But always they end with someone getting naked, so it usually works out for the best.

Albino Squid: davidphogan: Albino Squid: The odd thing is not that Nelson said it...it's that he's accurately describing what they are planning to do, per the quote from the head of the project. Though he describes it as a bag with a string rather than a lasso.

What's odd about that?

That a United States Senator said something accurate that sounds ridiculous, rather than their usual habit of saying something ridiculous that sounds ridiculous.


I guess I read about it long enough ago that it just doesn't sound that ridiculous to me.

The Δv required to get into Interstellar orbit will come from the tears of every engineer who's come up against the tyranny of the rocket equation.

The Δv required to get into an orbit around Earth will come from the tears of all the people who thought space was easy and then went and played Kerbal Space Program (which isn't really  thebest simulation, just okay).

It's going to take a lot of tears.

Why not send up a spaceship with four or more women in it and have them nag the asteroid into a moon orbit?

Also, if you want to bench-press 300 pounds, all you have to do is get under the weight and push.
 
2013-04-06 09:25:43 AM
It'll never work.  If it's a legitimate lasso attempt, the asteroid has ways to try to shut that whole thing down.

I guess you missed the fact that he's right, and was just using an analogy to describe what NASA actually wants to and thinks it can do.

You also might be interested to know that Bill Nelson also flew in space as a payload specialist on STS-61-C. Hardly a dumb guy. Oddly enough, Charles Bolden (you might know him as the NASA Administrator) was the person flying that one.

Orbiter, linked earlier, is a very good simulation of what getting a space plane into orbit is like.

As for KSP, it needs some work. The most glaring problem right now is it's aerodynamics model is all around bad - I mean, nose cones just add mass to your rocket, they don't actually help you get through the air, and as I've seen a few videos with flap abuse (you can literally use flaps to flap yourself into orbit). Scott Manley recently did a video where he popped a glider off a fast moving rover on Kerbin and it literally just hung in the air, unable to come down.

As for the rest of it, KSP is probably the best arcade simulator there is - it's easy to get into, and it lets you learn about cool stuff like Asparagus staging, the tyranny of the rocket equation, delta-v, and docking in space (which frankly kind of sucks in KSP).

/fine, it's the best simulator out there
