Company set to blast squadron of tiny satellites into space to mine asteroids

Deep Space Industries looks to mine asteroids for iron, nickel, water and rare platinum

A new company intends by 2015 to send a fleet of tiny satellites, known as cubesats into near-Earth space to mine passing asteroids for high-value metals.

Deep Space Industries asteroid mining proposal begins in 2015 when the company plans to send out a squadron of 55lb cubesats called Fireflies that will explore near-Earth space for two to six months looking for target asteroids

Then in 2016, Deep Space said it will begin launching 70-lb DragonFlies for round-trip visits that bring back samples.  The DragonFly expeditions will take two to four years, depending on the target, and will return 60 to 150 lbs of asteroid materiel.

Collecting asteroid metals is only part of the company's plans however.  DSI said it has a  has a patent-pending technology called the MicroGravity Foundry that can transform raw asteroid material into complex metal parts.  The MicroGravity Foundry is a 3D printer that uses lasers to draw patterns in a nickel-charged gas medium, causing the nickel to be deposited in precise patterns.

A much larger spacecraft known as a Harvestor-class machine could "return thousands of tons per year, producing water, propellant, metals, building materials and shielding for everything we do in space in decades to come.  Initial markets will be customers in space, where any substance is very expensive due to the cost of launching from Earth, over time, as costs drop and technologies improve we can then begin "exporting" back to Earth," the company stated.

The company envisions creating outposts that could offer satellite or spacecraft refueling for example.

Bringing back asteroid materials is only one part of the company's plans though.  DSI said it  has a patent-pending technology called the MicroGravity Foundry to transform raw asteroid material into complex metal parts in space.  The MicroGravity Foundry is a 3D printer that uses lasers to draw patterns in a nickel-charged gas medium, causing the nickel to be deposited in precise patterns, the company stated.

"Mining asteroids for rare metals alone isn't economical, but makes senses if you already are processing them for volatiles and bulk metals for in-space uses," said Mark Sonter, a member of the DSI Board of Directors.  "Turning asteroids into propellant and building materials damages no ecospheres since they are lifeless rocks left over from the formation of the solar system.  Several hundred thousand that cross near Earth are available."

The MicroGravity Foundry will enable early utilization of asteroid material to produce structural parts, fasteners, gears, and other components to repair in-space machinery and to create new space infrastructure, such as solar power satellites.  A version of the MGF process will be licensed to terrestrial users; the underlying process is more straightforward than those now employed to digitally print metal components, DSI stated.

 "Using resources harvested in space is the only way to afford permanent space development," said DSI CEO David Gump.  "More than 900 new asteroids that pass near Earth are discovered every year.  They can be like the Iron Range of Minnesota was for the Detroit car industry last century - a key resource located near where it was needed.  In this case, metals and fuel from asteroids can expand the in-space industries of this century.  That is our strategy."

If that strategy sound familiar it should.   Last year Google executives Larry Page and Eric Schmidt and filmmaker James Cameron said they would bankroll a venture to survey and eventually extract precious metals and rare minerals from asteroids that orbit near Earth. Planetary Resources, based in Bellevue, Wash., initially will focus on developing and selling extremely low-cost robotic spacecraft for surveying missions.

Planetary says asteroid resources have some unique characteristics that make them especially attractive. Unlike Earth, where heavier metals are close to the core, metals in asteroids are distributed throughout their body, making them easier to extract. Asteroids contain valuable and useful materials like iron, nickel, water and rare platinum group metals, often in significantly higher concentration than found in mines on Earth.
