The physics are feasible. The economics is a different story, said Cheng, who now leads space research at the Applied Physics Laboratory at Johns Hopkins University. He said hes hopeful that ventures such as Deep Space Industries can succeed as more companies venture into space, however.
If NASA can launch just the hardware and tank up in orbit, where the fuel is cheap, that means we could get to the Red Planet a lot sooner than we currently exsatellite companies Fireflies to scope out space rocks for miningpect, Gump said. That could also allow commercial satellite companies to extend the life of hardware thats now written off when fuel for maneuvering thrusters runs out.
A venture announced Tuesday in California hopes so.
Cheap access to space has been the sort-of Holy Grail for decades, and were not much closer to that than we were 50 years ago, said Hertzfeld, who is also an adviser to Planetary Resources.
If someone identifies a way to do something out there that makes a lot of money, and theres a lot of traffic and a bigger market, then the cost will come down, he said. Its a bit of a chicken and egg problem.
Space is a new legal frontier as well. The 1967 Outer Space Treaty provides for free access to all areas of celestial bodies by any nation, but isnt clear about commercial rights, said Henry Hertzfeld, who researches space policy at George Washington University. Until thats cleared up, aduedu4409.typepad.com that adds risk to any business venture, he said.
But Deep Space Industries Chairman Rick Tumlinson,2013-1-24 下午10:56:10. a longtime booster of private space efforts, said the company sees itself as the 21st-century version of the settlers and shopkeepers who followed the Lewis and Clark expedition into the American West.
Meteorites sit on a display tablesatellite companies Tuesday at the Deep Space Industries announcement of plans for the worlds first fleet of commercial asteroid-prospecting spacecraft at the Museum of Flying in Santa Monica, California.The goal is to extract metals, water and compounds that can be used to make spacecraft fuel from the chunks of rock that float within about 50 million kilometers (31 million miles) of Earth. Gump said the ability to produce fuel in space would be a boon for NASA,dna2163650.typepad.com. as the U.S. space agency shifts its focus toward exploring deeper into the solar system.
You dont see any space elevators. You dont see antigravity. You dont see warp drive, said Mankins, a former NASA scientist. There is really nothing the business plan Deep Space Industries is using that cannot be done with the technological research that has already been accomplished in laboratories across the planet.
If you give it one more month of active work in orbit, its worth about $5 (million) to $8 million to the owner of that satellite, Gump said.
But big enough for two companies thatwant to mine near-Earth asteroids?
As much as 90% of the weight of a prospective months-long Mars mission could be fuel -- and it costs between $5,000 and $10,000 per pound to put anything into space.
(CNN) -- Space, it has been said, is big. Really big.
Andrew Cheng, project scientist for the Eros probe NEAR-Shoemaker, said the big question cing commercial space ventures remains what it will cost to get their equipment off Earth.
Executives said Tuesday theyre also developing a foundry designed to produce metal parts from nickel, an element abundant in asteroids, and operate in space, and a class of Harvestor craft to extract valuable material from the asteroids.
Space is big. Theres room for everybody, he added.
Since the retirement of its space shuttles, NASA has hired out supply missions to the International Space Station to the private rocket company SpaceX. It completed the first commercial flight in October and is vying for a contract for manned flights into orbit alongside Boeing and Sierra Nevada.

One company may be a fluke. Two companies showing up -- thats the beginning of an industry, Tumlinson said.
Deep Space Industries says it wants to start sending miniature scout probes, dubbed Fireflies, on one-way missions to near-Earth asteroids as soon as 2015. Larger probes, Dragonflies, that satellite companies Fireflies to scope out space rocks for mining,will bring back 50- to 100-pound samples from prospective targets could be on their way by 2016, company CEO David Gump told reporters.
But John Mankins, the companys chief technology officer, said its plans are based on existing technology, not magic.
NASA landed a probe on the 20-mile-long asteroid 433 Eros in 2000, while Japans space agency not only landed its Hayabusa spacecraft on the roughly 1,700-foot asteroid Itokawa in 2007 but also returned it to Earth with small samples in 2010.
Tuesdays announcement comes nine months after the unveiling of a similar project by Planetary Resources,shunli367.typepad.com. a company led by space tourism pioneers Eric Anderson and Peter Diamandis. That group, backed by investors such as filmmaker James Cameron and Google executives Larry Page and Eric Schmidt, says it hopes to get its first unmanned probes into space by the end of 2013.
Deep Space Industries said it can build its first class of probes largely with off-the-shelf parts and book them on other launch vehicles, such as the French-built Ariane rockets or the Falcon boosters developed by SpaceX.
