New
venture 'to mine asteroids'
A
new venture is joining the effort to extract mineral resources on
asteroids.

The
announcement of plans by Deep Space Industries to exploit the rare
metals present in the space rocks turns asteroid mining into a
two-horse race.
The
other venture, Planetary Resources, went public with its proposals
last year.
Advocates
of asteroid mining hope it could turn into a trillion-dollar
business, but some scientists are highly sceptical of the idea.
Deep
Space Industries wants to send a fleet of asteroid-prospecting
spacecraft out into the Solar System to hunt for resources.
These
spacecraft, which the company has dubbed "Fireflies", would
use low-cost CubeSat components and benefit from discounted delivery
to space by ride-sharing on the launch of larger communications
satellites.
The
Fireflies would have a mass of about 55 lb (25 kg) and be launched
for the first time in 2015 on journeys of two to six months.
The
company then wants to launch bigger spacecraft - which it calls
"Dragonflies" - for round-trip visits that bring back
samples.
These
expeditions would take two to four years, depending on the target,
and would return 60 to 150 lbs of material from target asteroids.

Planetary Resources was the first firm to announce asteroid mining
proposals
"Using
resources harvested in space is the only way to afford permanent
space development," said the company's chief executive 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."
Asteroids
could yield precious minerals such as gold, platinum and rare-Earth
metals. But some are also thought to harbour water ice, which could
be used as a raw material for the manufacture of rocket propellant or
even breathable air.
The
other firm in the mining race, Planetary Resources, has backing from
several billionaire investors, including Google's Larry Page and Eric
Schmidt, software executive Charles Simonyi and filmmaker James
Cameron.
That
company wants to start by launching orbiting telescopes that would
identify suitable asteroid targets for mineral exploitation.
However,
some scientists struggle to see how cost-effective asteroid mining
could be, even with the high value of gold and platinum.
They
point out that an upcoming Nasa mission to return just 60g (two
ounces) of material from an asteroid will cost about $1bn.
