It's not like the asteroid could be brought down all at once. It would have to mined, and those billions of tons would have to be transported.

Because, Ive heard like a ton of equally plausible theories about why cannabis is illegal. ANd I dont think they can all be true.

I am particularly skeptical of the economic reasons. Because, it implies cannabis was some new invention. cannabis has been grown in America for at least as long as cotton. But the cotton industry still got strong. So the paper mills want to ban cannabis because it will eat away their market, even though cannabis has been used as paper for a lot longer?

I dont think a corporation, that owns the screwdrover patent, could ever ban screw drivers. not ever. Its just too stupid. Law makers wouldnt tolerate this, and the public wouldnt accept it. Its just ridiculous.

It becomes more plausible when we talk about cannabis. Obviously something made it illegal. So there is a correct explaination. I wasnt saying that it couldnt be that some group, out of economic interests made the government do that. Im just saying its way too easy to come up with a half baked theory about this.

It's not hard. Literally, all you have to do is figure out its orbit. Which we have already done, I believe.

It's easier to mine in microgravity.

It's easier to land, load, build on, and fly away from a body in microgravity.

>Not to mention we would have to give it an orbit, which would be harder to do than crashing it into the moon.(both in power needed to move it, and maintaining it in an orbit that doesnt destroy 500 satellites/crash into earth)

That's pretty enormously wrong. For one thing, it's already in an orbit. Moving it closer to Earth could be accomplished with a solar sail and some time, or an ion thruster and some time, or something similar. Crashing it into the Moon would take more time and more energy, and provide no perceivable benefit.

>Also bonus points, use all the iron/leftover to build a bigger moon base, which we will fucking need to go to mars/further.

>Not to mention if you just throw the ore into the ocean, no fuel is needed to move it, at all.

First you have to take the ore from the asteroid. Then you have to move the ore to Earth, expending fuel. Then you have to drop it in a controlled fashion, expending fuel. Then you have to collect it from the ocean, expending fuel.

I didn't suggest we leave it where it is. I suggested we move it closer.

Moving it into a stable orbit, and maintaining it is going to take way way more energy than just crashing it into the moon.

What extra force do you keep thinking we need? Its the same as your idea, we just change the orbit, 1-2 degree is enough for it to crash into the moon.

I keep saying we'd move the asteroid. Perhaps to a Lagrange Point, where it could remain roughly in one place for as long as we needed it. The cost, in time and energy, of doing this might be prohibitive. A near-Earth orbit could be almost as good, without the major drawbacks of a Moonshot.

If you have to spend any significant energy to maintain its orbit, you have done it wrong.

EXCELLENT! You are all on board! With a simple launch platform we can get a single 250,000 ton mining rig into orbit. The crew will be brought to it gently in "space planes" similar to or perhaps based on the SABRE project. They will unpack the rig from it's launch state to its travel state and fly it to that asteroid or one of the many near earth asteroids just like it. It will then begin carving up the asteroid and launching the valuable pieces in easy to catch re-entry packages making soft landings or splash downs.

It's just that simple folks.

Fortunately, although L1 and L2 are both being used, they aren't heavily populated. L1 has fewer occupants. It might turn out to be easiest to use L1 or L2 and just provide for the necessary adjustments to the positions of the other occupants. If not, L4 or L5 are open for business. L3 is fairly far, but it is also an option, of course. Which point, if any, is used depends on a whole bunch of things, not the least of which is what happens in the years leading up to the asteroid's course correction.

The main point here is that landing the asteroid on any significant body would just make it harder to get its resources out to where they're needed, due to gravity. We want to use these billions of tons of metals primarily in space, anyway.

>> No.3019644

Plenty of people here implying it will be too expensive to retrieve a 30 trillion dollar asteroid. So, does someone think getting a mining rig into orbit and carving up the asteroid would cost more than 30 trillion? The only way to kill the profit or make it undesirable is to show the cost approaching within ten percent of 30 trillion. And that's WITHOUT derping and utilizing NASA costs.

Because it should only be about 100 Billion, an intentional overestimate of the cost. This will grant a hefty profit for even the tiny and low metal content asteroid in the OP.

Carve into it! Move the pieces where you need them! Land only what needs to be landed. Put into orbits what needs to go into those orbits for their construction.

There are cost limits, mass limits for launch of the main rig, mass limits for space plane launches, tech limits as to what that mass can contain in any launch, cost limits as to what tech can be changed, et cetera. 100 billion is an over-estimation in 2009 USD, but it's not THAT great of an over-estimation.

Mark my words, there will NEVER be an airbreathing engine that produces appreciable thrust at greater than ~4.5 km/s/mach 13. Even if you manage to slow the air down enough with your precooler, you'll never be able to accelerate it back up to more than these velocities, seeing how even a pure rocket cannot exceed this.

You would need to balance out the demand so as to not fuck the market completely. I say wait a bit until we are much more numerous as a species.

4.5 km/s, with a cryogenic, low-density LH2 propellant that involves massive, draggy tankage that will likely add about 50-75% to your drag losses, given your high-Q lifting (rather than ballistic) ascent... or you could switch to a higher-density hydrocarbon fuel, and run out of juice at about 3.5 km/s... and keep in mind, these are theoretical MAXIMUMS.

When it comes down to it, ditching your oxidizer at the expense of 2x the fuel, 10x the engine weight, and still only getting halfway there is not worth the trouble.

*facepalm*
You DO realize that even pure rockets use different engines for different altitudes, right? Upper-stage engines are always optimized for vacuum thrust, while lower-stages are optimized for a compromise optimum altitude at somewhere around 10-25% of ambient sea level pressure.

There's a reason they do things the way they do now. There's a reason SSTO hasn't been done from Earth. There's a reason they don't use horizontal takeoff or airbreathing engines for space launch. When it comes down to it, these technologies are pure novelties that, while indeed worth putting research into, will ultimately fall to nothing but filler material for lit-major sci-fi writers.

>> No.3020668

>>3020605
Yes, I am aware that in multi-stage rockets each stage is specialized for its altitude. How does that make SSTO impossible?

And one possibility of the spaceplane is that it will in fact be two planes, a lifter plane with the actual orbital vehicle. As long as they both come back for refuel, it's fine.

>> No.3020779

>>3020668
SSTO is not impossible; quite to the contrary, the Atlas rocket was theoretically capable of it way the fuck back in 1962, if you simply launched it without an appreciable payload.

The point is that these practices and technologies are IMPRACTICAL. COULD you launch an Atlas in an SSTO configuration? Certainly, but it'd be pointless since the whole rocket is expendable anyways. COULD you build an airbreathing rocket that will follow a lifting, high-Q trajectory and burn atmospheric oxygen? Yes, but in the end it'd be larger, heavier, more expensive and have less payload than a plain ballistic 2STO rocket. Sometimes, technological developments are actually superior to the alternatives; when these are found, they usually quickly replace existing versions (see: regeneratively-cooled rocket engines; photovoltaic power sources for satellites). But sometimes a technology just doesn't pan out; airbreathing space rockets are one of those technologies.

Have you heard of 1.5 stage rockets. Several cores with propellant cross feed, so when the boosters drop off the center core is full. Use this with an aerospike center engine and you have a valid 1.5 stage to orbit.

Heck, if you want to talk about the way we do things now, why the fuck have we stuck with the space shuttle for so long, and why is our best replacement for it NOTHING? That thing is horribly overpriced for its job.

Just because there is something we are not doing right now, doesn't mean it's terrible. When you get right down to it, we haven't even tried. Heck, technically Virgin Galactic tried and their little space plane works. My original idea was basically an upscaled version of that. If SABRE doesn't pan out, whatever. The point is the thing that moves people into LEO needs re-useable, requiring only a refuel.
