back to article 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.

Well, why don't we offset the import, by exporting junk, the French, etc, into the depths of space?

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?

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.

"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.

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.

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.

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.

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.

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.

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.
