Asteroid miners to strap 'scopes to new Virgin Galactic rocket
Washington-based Planetary Resources is pursuing the dream of mining near-Earth asteroids, signing a deal with the UK's Virgin Galactic for payload services. Planetary Resoures wants to use Virgin Galactic's LauncherOne booster to blast a series of robot craft into space to pave the way for asteroid mining. The firm's Arkyd-100 …

Surely?
If people start mining hundreds of tons (or thousands even) of space rock and bringing them to earth that will affect the earths orbit around the sun (Increase earth mass, increase gravitational effect on the sun, drag earth into firey furnace)
how much space gold would that take?
Re: Surely?
That has to be offset against the amount of mass that has been (and will be) taken away from the earth via spacecraft and their contents. As I understand it, large amounts of matter (space dust, small meteors, etc) land on the earth on a yearly basis, so that has to be factored in as well.
I've no idea what the overall effect on the earth's orbit is, or would be; but someone will be along to tell us shortly.
Re: Surely?
I'm no astroboffin but my understanding is our orbit is very slowly moving away from the Sun. We'd need a lot of space gold to alter that trend.
Re: Surely?
Hmmm, I guess that the amount of stuff sent off earth won't be that much (yet, probably increasing exponentially though)
But if large amounts are hitting earth every year then we are all dooooooomed I tells ya.....
I'm getting out of here on the first available space plane.
Re: Surely?
The mass of the entire asteroid belt is estimated at approx 4% of the mass of the moon. (disclaimer - from wikipedia). Therefore we could move the whole belt here and still have pretty minor impact.
Re: Surely?
Well, why don't we offset the import, by exporting junk, the French, etc, into the depths of space?
Re: Surely?
surely that would be lots and lots of not minor in the least impacts.
Re: Surely?
"...exporting... ...the French... ...into the depths of space?"
What did space ever do to deserve that?
Mine's the one with the beret stuffed in the pocket.
Re: Surely?
<Shortly> BBC's More or Less covered this and it turns out we're (probably/roughly/approximately) losing 50,000 metric tons a year: http://www.bbc.co.uk/news/magazine-16787636 ...
Re: Surely?
According to the net, the Earth gains about a million tonnes of space debris per year. Probably quite a lot of water. Which is infinitesimal in terms of changing its orbit.
For comparison, total world steel production is about 1.5bn tonnes per year. But we probably wouldn't want to bring iron ore down - we have loads of iron ore here. World total gold production is about 2,500 tonnes, so we could really flood that market with very little weight penalty.

Valuable stuff?
Does anyone yet know if these asteroids actually contain significant quantities of 'valuable stuff' (or are likely to)? Or is this more of a speculative venture?
Re: Valuable stuff?
I suspect a new bubble. In SPAAAACE!*
* if overusing "in SPAAAACE" is good enough for El Reg it's good enough for me.
Re: Valuable stuff?
The most valuable stuff they could get access to would be materials to produce/refine rocket fuel/water in depots floating around in strategic locations in the near earth orbit and further out in the solar system.
Returning material to earth, although perhaps important from a PR point of view probably doesn't have a very good economic basis.
Re: Valuable stuff?
"Returning material to earth, although perhaps important from a PR point of view probably doesn't have a very good economic basis."
I wonder. The asteroids themselves can presumably provide something to use as a propellant, so all we have to do is add energy and we can move any amount we want. Maybe (from one of my favourite sci-fi books) get whole asteroids into Earth orbit and then start mining and refining them there. Add a space elevator (or maybe figure out a way to just drop stuff down from orbit), and there really isn't much limit.
Re: Valuable stuff?
10 Million for 225 Kg is not cheap by any means, it's a rip-off!
Re: Valuable stuff?
"...or maybe figure out a way to just drop stuff down from orbit..."
Easy. If you're in the business of killing enough of its relative velocity that getting it into Earth orbit is feasible, you might as well just give it a velocity of bugger all relative to the surface, point it at somewhere unimportant[1] and wait. Then mine the results in the conventional manner once the dust has settled.
[1] E.g. Swindon. You might even get government funding under "urban regeneration".....
Re: Valuable stuff?
Despite his two thumbs down, Gorand2 is right.
10 million dollars for 225Kg? Do the math!
SpaceX is offering a secondary payload (light and/or small stuff) for very reasonable prices and, truth be told, I think you'd get your payload up there a lot sooner than waiting for Virgin.
Quite a few pre-sold Sub-Orbital flights bought & paid for but nary a one has taken place and probably won't this year...
Re: Valuable stuff?
I don't know any school that can afford prices like that. $20k will get an adjunct, a new lunch lady, a janitor for a year or offset the cost of an SRO or maybe replace all the flickering lighting that makes everyone feel like they're on a shitty spaceship.
I'm 6'5" and weigh 15 stones. I will gladly pay $3k for myself but that's about all I'm willing to pay for a joyride. No way I'm going to pay $4.3M+ unless it takes me somewhere cool. For $1.5k I can visit the opposite side of the planet and experience new cultures. For $4M I get vertigo and a view I've seen many time from photos? No thanks.
$3-5k should be the milepost. More than that and the general population simply can't afford to go to space.
Re: Valuable stuff?

Yeah, even Easy Jet don't charge THAT much!

$45/gram for luggage sounds about right for Easy jet
Re: Valuable stuff?
>[1] E.g. Swindon. You might even get government funding under "urban regeneration".....
Oi! You could at least wait until I'm on holiday. Although, even then that would harm my cats and I would be displeased.
I reckon it's all a cover-up for the new orbital Anvil delivery service..
1,500 accessible asteroids?
OK, so what if there are 1,500 asteroids that they claim they could get to. What they happen to forget to mention is that pretty much all of them pass Earth at a hel of a velocity (measured in kilometers per *second*) which makes matching orbits with them just a little bit difficult (and remember, if they mine the asteroids then they have to match orbit with the Earth again on the next pass).
Personally I think this is just a scam. Shout about a big project that looks feasible to idiots (= most VCs in my experience), pay yourself a big salery + bonuses for a few years, then allow the whole thing to collapse ("sorry, idea just did not work out"), move on to the next scam.
Re: 1,500 accessible asteroids?
Not sure that "scam" is right. "Rich man's toy" perhaps, or "ego trip" if you want to be cynical. But I don't think the investors are really expecting a huge chance of a big pay off.
Re: 1,500 accessible asteroids?
You obviously don't have much experience with VC's. They set the salary caps on all C-level and director positions. They are gambling. Not just throwing money at companies.
Re: 1,500 accessible asteroids?
Clearly, none.
Not to mention that VCs have people like me that advise them on the viability and risk of projects. Deals that come to me for technical review, more often my rejection is because the business model is bad or the pitch documents smell like bullshit. If the idea is good, we can engage an EIR, drop me in to help with the technical stuff, or build some money into the investment for outside consultants who can guide them towards the launchpad. I don't get into the books, but I know from talking about taking an investment for a project I have that you are NOT getting rich until your company begins to haul in revenue. That money goes to developers, QA, hardware, support, facilities, marketing, and designers.
Where do I sign up?
I mean, how hard can it be? I've played Eve Online, so I'm all trained up and stuff.
Re: Where do I sign up?
Playing EVE Online I'm surprised you have time to read the reg.
Re: Where do I sign up?
Nah, not really. I tried it once. Though it was pants.
I see I got a thumbs down, so somebody actually though I was being serious?
Re: Where do I sign up?
"Playing EVE Online I'm surprised you have time to read the reg."
Clearly, another AFK miner, in need of a good ganking.
Moon is a harsh mistress
I just picture all the clueless noobz in the middle of the desert waiting for the first valuable mineral drop from orbit.
Re: Moon is a harsh mistress
I initially read that as "...mineral dump..." and nearly aspirated my coffee.
Re: Moon is a harsh mistress
Does wanting to be the bloke running a concession stand local to the desert concerned and flogging baseball mitts to those same clueless noobz make me a bad person?
Re: Moon is a harsh mistress
Hope you dont mean a middle eastern desert, they already have enough minerals and oil, maybe it could be dumped from orbit a little closer to home, maybe Milton Keynes or Slough?
Re: Moon is a harsh mistress
Come, friendly rocks, and fall on Slough!
It isn't fit for humans now,
The only grass is skunk, but oh wow!
Swarm over, Death!
Come, rocks and crush to smithereens
Non-air-conditioned, dowdy canteens,
Tinned fruit, tinned meat, tinned milk, tinned beans,
Tinned minds, tinned brains.

Really very expensive
The SpaceX Falcon 9 costs 50-60M$ per launch and will lift 13 150kg to LEO. Which amounts to approximately 60 times the mass for only 6 times the cost! Plus you can launch _now_, not in 4 years.
I really don't get how all these companies (ULA is the worst) get away trumpeting the wonderful rockets they'll have in 4 to 10 years, when SpaceX has a better and much cheaper rocket right now.
I want
my singleship now please.
Survey asteroids over long period
Find the ones that have a high density from gravitation perturbations of the others
Send prospectors out in covered singleships
Find high densities of gold/platinum/uranium/unobtainium
Fit asteroid with ion motor
Fly it into L4
Melt it with solar mirrors
Spin it to refine
Let it cool
Take the lovely minerals
Match Earth velocity
Drop on desert region
...
Profit.
I'm not much of a salesman.
Re: I want
@Andy Farley
Your strategy gem reminds me of the South Park gnome episode with the slide that said "collect underpants - ? - profit".
Actually, that's probably their VC pitch: "collect asteroids - ? - profit"
Tittle
You had miner, rocket, scope, strap, and virgin and that's the best title you could think of?
The most useful thing you could do...
... would be to gather half a dozen decent sized ice asteroids (say, about 50 miles across) and then drop them on Mars.
That way you would get a whole new planet for your money...
Re: The most useful thing you could do...
Check out (Asimov's?) short story The Martian Way. A small group of ships (3, I think) head of to Saturn's rings (ice chunks, remember?), find a nice big chunk of ice (about a mile across, I seem to remember) and fly it back to Mars, using a small percentage of the ice in the chunk as fuel for a fast flight.
Today, of course, I don't think you'll find chunks in that size but you could combine smaller bits to make a bigger one to be sent to Mars, remembering to have it go through the atmosphere & break up, which is better than smashing it into the surface of Mars. You could do something similar with comets, too.
50 miles across would be a bit big though.
Launch costs
The main benefit may be the orbit insertion vs launch costs.
Yes $10m/225kg isn't cheap.
However using this may have one major benefit over say Falcon 9 or Ariane 5;
The orbit you wish to be inserted into, the conventional solutions will be able to to lift 225kg into any orbit you wish, but the target orbit for the rocket will be determined by the primary payload.
This has no such limitation, additionally being air launched would have a lower hindrance on weight to specific orbits.
