A new asteroid-mining company, Deep Space Industries, Inc., launches Today
- dsugarman 14y ago"Deep Space Industries will also focus on extracting asteroid water, which can be split into its constituent hydrogen and oxygen — the chief components of rocket fuel." To do this, you need a lot of energy, it is essentially charging a battery. If this was really feasible wouldn't we be using solar panels to separate water into hydrogen on Earth? Do solar panels in space have the potential for far greater energy output due to less atmospheric constraints?
- typpo 14y agoThe reason this is an attractive prospect in space and not on Earth is that the cost of getting rocket fuel off Earth is quite high. Once fuel becomes available in space, it makes refueling possible and lowers the cost of further activity or exploration.
- gte910h 14y agoTo take water from the surface of the earth, separated or not, you have to spend a CRAP TON of energy. Moving the fuel to release such energy to space is almost by definition cheaper than moving the separated storage medium.
- maaku 14y ago> To do this, you need a lot of energy, it is essentially charging a battery. If this was really feasible wouldn't we be using solar panels to separate water into hydrogen on Earth? We do. If you buy commercial hydrogen, it was probably extracted by water by that process (although other processes are possible), using energy from the grid of which some percent is solar. So what exactly is your point anyway? The needs in space are far different than on Earth. Solar energy is abundant and available 24/7, but stored energy is needed by rocket engines in large amounts and all at once.
- tarice 14y agoIn space, the atmosphere can't filter out any of the sunlight, nor can clouds/water absorb some of its energy, which results in about 30% more energy[1]. Plus, if you're not near any objects that can block the sun (i.e. Earth/Moon), you get full, intense sunlight 24-hours a day. And you can use some of that sunlight to just directly heat the water, which makes it easier to split. Given all that, I'd say that it's very likely you could get enough energy to split water in space. [1] http://en.wikipedia.org/wiki/Sunlight http://en.wikipedia.org/wiki/Sunlight
- daeken 14y agoNot to mention that if you're in a near-zero gravity environment, you really don't have to do anything to keep the solar panels in place; structures just to keep things upright on Earth are expensive and bulky. Space architecture is so cool.
- samwillis 14y ago<pedantic> 'Launches'? they aren't launching, they are unveiling themselves. No Launch yet... that's planned for 2015. Sorry.... </pedantic>
- mark-r 14y agoThe pun appears to be the work of whoever submitted the link, the proper page title is "Asteroid-Mining Project Aims for Deep-Space Colonies".
- cryptoz 14y agoI submitted the link; the title is from the first sentence of the article: "A new asteroid-mining company launches Tuesday with the goal of helping humanity expand across the solar system by tapping the vast riches of space rocks." I used that instead as the first one is ambiguous, and would likely be referring to Planetary Resources without context.
- cuttooth 14y agoEVE Online is now EVE IRL, I suppose.
- iuguy 14y agoFor an interesting look at the impact of the last time a whole load of expensive and rare materials were brought home from a new world, see here[1]. It's also worth looking into the price revolution[2], a 150 year period of time where the import of unheard of masses of gold and silver into European markets had a startlingly unstable effect on the Spanish economy.

- veres_ya 14y agoIf you want to extract useful materials from asteroids, you should: automatic closed-loop enterprise. Would offer an option:Delivery module. The module is being introduced to the surface. Telemetry control robots to find no need for drilling locations. After finding the robots are already automatically convey the ore to the mill. after remelting and packaging materials, to the launch site and along the orbit of Jupiter to orbit the Earte or or direct route. Earth orbit packing large lot in the descent module. Delivery to the surface and rebounding. True, I have no idea what means does it take to create it in one lifetime. If you have such finance, even with them, it will take about 20 years.Require about 30 programmers, 10-18 engineers metals and alloys, 8 chemists and useful ideas. In addition to the number of staff you still have to pay not only the design, but also materials for assembly. You really possess such means? This is not an idle question. Since this idea was born in the USSR, but has not received strength. However, this is the only way of survival.
