CAPE CANAVERAL, Florida | Thu Jan 31, 2013 1:14pm EST

CAPE CANAVERAL, Florida (Reuters) - Space shuttle Columbia's flying days came to an abrupt and tragic end on February 1, 2003, when damage from a broken wing crescendo, dooming the seven astronauts aboard.

Although Columbia now lies in pieces, its mission is not over.

The recovered wreckage, painstakingly retrieved from Texas and Louisiana for months after the accident, was preserved for a unique archive and education program at the Kennedy Space Center in Florida.

"I can talk about safety, but once I open those doors and folks enter into the room, it becomes a different conversation," said Michael Ciannilli, who oversees NASA's Columbia Research and Preservation Office. "When you come face to face with Columbia in the room, it becomes real. It becomes extremely real."

Ten years ago, Columbia was on its 28th mission, a rare research initiative in the midst of International Space Station construction flights.

The crew included the first astronaut from Israel, Ilan Ramon, and six Americans -- commander Richard Husband, pilot William McCool, flight engineer Kalpana Chawla, payload commander Michael Anderson and flight surgeons David Brown and Laurel Clark.

After 16 days in space, the shuttle was gliding back to Florida for landing when it broke apart due to wing damage that had unknowingly occurred during launch.

Accident investigators determined that a chunk of insulating foam from the shuttle's fuel tank had fallen off 81 seconds after liftoff and hit a carbon composite wing panel that turned out to be unexpectedly fragile. The breach proved fatal.

NASA had no idea falling foam debris, a common occurrence during shuttle launches, could do so much damage.

"One of the most important things that came from Columbia is to really learn to listen to your hardware. It's talking to you," Ciannilli said.

Pieces of Columbia's heat shield, including wing panels and protective thermal tiles, are among the most requested items for study from the archive.

Upon request, NASA lends specific components to researchers and educational institutes for analysis. In addition to NASA field centers and aerospace companies, program participants include Caterpillar, the Colorado School of Mines and Ohio State University.

By understanding the dynamics of flight and how specific parts of Columbia were impacted, the hope is engineers will be able to design safer ships in the future.

The collection includes more than 84,000 individual pieces, most of which are cataloged and boxed. A handful of materials and structures -- a tire, a wing panel, pieces of tile -- are on display in the front part of a 7,000-square-foot room inside the Vehicle Assembly Building where the archive is housed.

"Sometimes I walk into the room, especially if I'm alone, and it comes back, some of the emotions, some of the feeling, some of the memories," Ciannilli said. "I lived the recovery operation in Texas, so you have these moments where you flash back."

"Some days are a little bit more introspective and difficult, but I really counter that with the fact that I've seen so much good come out of it. Every single tour engages in a conversation about safety," he said.

The Vehicle Assembly Building was once used to piece together space shuttles for flight, but it, like most of the Kennedy Space Center, is in the midst of a transition following the end of the shuttle program in 2011.

Only Columbia remains at the space center. Sisterships Discovery and Endeavour were relocated to museums, and Atlantis was transferred to Kennedy Space Center's privately operated visitors complex.

"We teach the story, show the effects of the accident and show the fixes that we put into place," Ciannilli said. "Columbia's mission was a mission of education and research. We try to continue that in their name."

Rocket blasts off with new NASA communications satellite
Jan 31st 2013, 02:59

By Irene Klotz

CAPE CANAVERAL, Florida | Wed Jan 30, 2013 9:59pm EST

CAPE CANAVERAL, Florida (Reuters) - An unmanned Atlas 5 rocket blasted off on Wednesday to put the first of a new generation of NASA communications satellites into orbit, where it will support the International Space Station, the Hubble Space Telescope and other spacecraft.

The 191-foot (58-metre) rocket lifted off at 8:48 p.m. (0148 GMT Thursday), the first of 13 planned launches in 2013 from the Cape Canaveral Air Force Station just south of NASA's Kennedy Space Center.

Once in position 22,300 miles above the planet, the Tracking and Data Relay Satellite, known as TDRS and built by Boeing Co, will join a seven-member network that tracks rocket launches and relays communications to and from the space station, the Hubble observatory and other spacecraft circling Earth.

Two other TDRS spacecraft were decommissioned in 2009 and 2011 respectively and shifted into higher "graveyard" orbits. A third satellite was lost in the 1986 space shuttle Challenger accident.

NASA used its space shuttle fleet for launching the satellites until 1995, then switched in 2000 to unmanned Atlas rockets, manufactured by United Space Alliance, a partnership of Lockheed Martin and Boeing.

With six operational satellites and a seventh spare, NASA can track and communicate with spacecraft in lower orbits, such as the space station, which flies about 250 miles above Earth.

Before 1983 when the first TDRS was launched, NASA relied on ground-based communications, occasionally supplemented with airplanes and ships, which was expensive to maintain and provided only a fraction of the coverage of an orbiting network.

Three second-generation TDRS spacecraft were launched from 2000 to 2002. Wednesday's launch was the first of three planned third-generation satellites needed to replace aging members of the constellation.

"It's been a long time since we launched the last one," NASA's TDRS project manager, Jeffrey Gramling, told reporters at a news conference before the launch.

Most of the spacecraft are well beyond their 10-year design life, he added.

Initially developed to support the space shuttle and space station programs, the TDRS network now serves a variety of NASA spacecraft and commercial users such as Space Exploration Technologies and foreign space agencies flying cargo ships to and from the station, a $100 billion research laboratory staffed by rotating crews of astronauts and cosmonauts.

The new spacecraft, which cost between $350 million and $400 million, will take about 10 days to reach its intended orbit. It will then go through a three-month checkout before it is put into service, Gramling said.

The 12th and 13th TDRS satellites are targeted for launch in 2014 and December 2015.

Science cafes offer a sip of learning
Jan 30th 2013, 15:35

By Barbara Liston

ORLANDO, Florida | Wed Jan 30, 2013 10:35am EST

ORLANDO, Florida (Reuters) - Americans may be turning away from the hard sciences at universities, but they are increasingly showing up at "science cafes" in local bars and restaurants to listen to scientific talks over a drink or a meal.

Want a beer with that biology? Or perhaps a burger with the works to complement the theory of everything?

Science cafes have sprouted in almost every state including a tapas restaurant near downtown Orlando where Sean Walsh, 27, a graphic designer, describes himself and his friends as some of the laymen in the crowd.

"We just want to learn and whatever we take in, we take in. But we're also socializing and having a nice time," said Walsh, who a drank beer, ate Tater Tots and learned a little about asteroids and radiation at two recent events.

Others in the crowd come with scientific credentials to hear particular scientists lecture on a narrowly focused field of interest.

But the typical participant brings at least some college-level education or at least a lively curiosity, said Edward Haddad, executive director of the Florida Academy of Sciences, which helped start up Orlando's original cafe and organizes the events.

"You're going to engage the (National Public Radio) crowd very easily here," said Linda Walters, a marine conservation biologist from the University of Central Florida who has lectured twice at the Orlando-area science cafes.

Haddad said the current national push to increase the number of U.S. graduates in science, technology, engineering and math, or the STEM fields, is driving up the number of science cafes.

In Orlando, an Orange County STEM Council consisting of business, government and educational leaders recently asked Haddad to help two interested parties launch new science cafes in the downtown library and in a large new town development.

The U.S. science cafe movement grew out of Cafe Scientifique in the United Kingdom. The first Cafe Scientifique popped up in Leeds in 1998 as a regularly scheduled event where all interested parties could participate in informal forums about the latest in science and technology.

Traditionally held in pubs and restaurants, the Cafe Scientifique would start as a short lecture, followed by a short break to re-fill glasses, and then an open discussion, according to the organization's website.

The American movement of independent cafes is loosely organized at the sciencecafe.org website created by public broadcaster WGBH's NOVA science program. Haddad said NOVA several years ago provided a few hundred dollars of seed money to groups around the country that wanted to start a cafe.

However, anyone with a venue, a speaker and a marketing plan can start one. On the sciencecafe.org website, an interactive map shows the location of cafes across the United States and around the globe from Islamabad, Pakistan, to Antwerp, Belgium, to the Hawaiian islands.

Some cafes have cropped up in bookstores, theaters and high school campuses.

In Viera, Florida, about 60 mostly retirees regularly pack a pizzeria to hear speakers from the well-regarded Brevard Zoo or NASA's nearby Kennedy Space Center. In Daytona Beach, scientists from the internationally known Embry-Riddle Aeronautical University draw standing-room-only crowds at a local coffee shop.

Haddad said his hope for the cafes is to engage the public and generate excitement about the STEM fields that might filter down to the next generation.

"My feeling is STEM begins at home, with students who are being brought up by parents or relatives who have some interest in science and may encourage them to do that," Haddad said.

Attending a cafe does not guarantee a speaker as engaging as the popular host of television programs Bill Nye the Science Guy, as Walsh learned when he got lost in the extensive jargon of one lecture.

"I don't know that every scientist is gifted with the ability to work a crowd as well as deliver a lecture on targeted radiation therapy for tumors," said Walsh. "If you can find one that hits both those things, they should have their own television show."

Reuters: Science News: Scientists find genetic clue to severe flu among Chinese

Scientists find genetic clue to severe flu among Chinese
Jan 29th 2013, 16:13

LONDON | Tue Jan 29, 2013 11:13am EST

LONDON (Reuters) - British and Chinese scientists have found a genetic variant which explains why Chinese populations may be more vulnerable to the H1N1 virus, commonly known as swine flu.

The discovery of the variant could help doctors find those people at high risk of severe flu and prioritize them for treatment, researchers said.

It may also help explain why new strains of flu virus often emerge first in Asia, where the variant known as rs12252-C is more common in the population than elsewhere, they said.

"Understanding why some people may be worse affected than others is crucial in improving our ability to manage flu epidemics and to prevent people dying from the virus," said Tao Dong at Britain's Oxford University, who led the study.

The research, published in the journal Nature Communications on Tuesday, found that having the rs12252-C variant could increase the chances of severe infection by six times.

H1N1 swine flu swept around the world in 2009 and 2010. A study published last week estimated at least one in five people worldwide were infected and around 200,000 killed in the first year of the outbreak, which was declared a pandemic by the World Health Organisation in June 2009.

Previous research has found that rs12252-C is linked to more severe flu infections.

For this study, researchers focused on the variant because it is 100 times more common in Han Chinese, the predominant ethnic group in China, than in Caucasian populations indigenous to West Asia and Europe. The variant is present in the genetic make-up of about 1 in 3,000 people in Caucasian populations.

The results showed it was present in 69 percent of Chinese patients with severe pandemic H1N1 in 2009 compared with 25 percent who only had a mild version of the infection.

Andrew McMichael of Oxford's human immunology unit said further studies are now needed to look in more detail at the gene variant's effect on flu severity in different populations.

"It remains to be seen how this gene affects the whole picture of influenza in China and South East Asia but it might help explain why new influenza viruses often first appear in this region of the world," he said in a statement.

DUBAI | Mon Jan 28, 2013 7:30pm EST

DUBAI (Reuters) - Iran said on Monday it had launched a live monkey into space, seeking to show off missile systems that have alarmed the West because the technology could potentially be used to deliver a nuclear warhead.

The Defense Ministry announced the launch as world powers sought to agree a date and venue with Iran for resuming talks to resolve a standoff with the West over Tehran's contested nuclear program before it degenerates into a new Middle East war.

Efforts to nail down a new meeting have failed repeatedly and the powers fear Iran is exploiting the diplomatic vacuum to hone the means to produce nuclear weapons.

The Islamic Republic denies seeking weapons capability and says it seeks only electricity from its uranium enrichment so it can export more of its considerable oil wealth.

The powers have proposed new talks in February, a spokesman for the European Union's foreign policy chief said on Monday, hours after Russia urged all concerned to "stop behaving like children" and commit to a meeting.

Iran earlier in the day denied media reports of a major explosion at one of its most sensitive, underground enrichment plants, describing them as Western propaganda designed to influence the nuclear talks.

The Defence Ministry said the space launch of the monkey coincided "with the days of" the Prophet Mohammad's birthday, which was last week, but gave no date, according to a statement carried by the official news agency IRNA.

The launch was "another giant step" in space technology and biological research "which is the monopoly of a few countries", the statement said.

The small grey monkey was pictured strapped into a padded seat and being loaded into the Kavoshgar rocket dubbed "Pishgam" (Pioneer) which state media said reached a height of more than 120 km (75 miles).

"This shipment returned safely to Earth with the anticipated speed along with the live organism," Defence Minister Ahmad Vahidi told the semi-official Fars news agency. "The launch of Kavoshgar and its retrieval is the first step towards sending humans into space in the next phase."

There was no independent confirmation of the launch.

SIGNIFICANT FEAT

In Washington, U.S. State Department spokeswoman Victoria Nuland told reporters she could not confirm whether Iran had successfully sent a monkey into space or conducted any launch at all, saying that if it had done so "it's a serious concern."

Nuland said such a launch would violate U.N. Security Council Resolution 1929, whose text bars Iran from "any activity related to ballistic missiles capable of delivering nuclear weapons, including launches using ballistic missile technology."

The West worries that long-range ballistic technology used to propel Iranian satellites into orbit could be put to use dispatching nuclear warheads to a target.

Bruno Gruselle of France's Foundation for Strategic Research said that if the monkey launch report were true it would suggest a "quite significant" engineering feat by Iran.

"If you can show that you are able to protect a vehicle of this sort from re-entry, then you can probably protect a military warhead and make it survive the high temperatures and high pressures of re-entering," Gruselle said.

The monkey launch would be similar to sending up a satellite weighing some 2,000 kg (4,400 pounds), he said. Success would suggest a capacity to deploy a surface-to-surface missile with a range of a few thousand kilometers (miles).

Michael Elleman, a missile expert at the International Institute for Strategic Studies think-tank, said Iran had demonstrated "no new military or strategic capability" with the launch.

"Nonetheless, Iran has an ambitious space exploration program that includes the goal of placing a human in space in the next five or so years and a human-inhabited orbital capsule by the end of the decade," Elleman said. "Today's achievement is one step toward the goal, albeit a small one."

The Islamic Republic announced plans in 2011 to send a monkey into space, but that attempt was reported to have failed.

Nuclear-weapons capability requires three components - enough fissile material such as highly enriched uranium, a reliable weapons device miniaturized to fit into a missile cone, and an effective delivery system, such as a ballistic missile that can grow out of a space launch program.

Iran's efforts to develop and test ballistic missiles and build a space launch capability have contributed to Israeli calls for pre-emptive strikes on Iranian nuclear sites and billions of dollars of U.S. ballistic missile defence spending.

MANOEUVRING OVER NEXT TALKS

A spokesman for EU foreign policy chief Catherine Ashton said the powers had offered a February meeting to Iran, after a proposal to meet at the end of January was refused.

"Iran did not accept our offer to go to Istanbul on January 28 and 29 and so we have offered new dates in February. We have continued to offer dates since December. We are disappointed the Iranians have not yet agreed," Michael Mann reporters.

He said Iranian negotiators had imposed new conditions for resuming talks and that EU powers were concerned this might be a stalling tactic. The last in a sporadic series of fruitless talks was held last June.

Iranian officials deny blame for the delays and say Western countries squandered opportunities for meetings by waiting until after the U.S. presidential election in November.

"We have always said that we are ready to negotiate until a result is reached and we have never broken off discussions," IRNA quoted Iranian Foreign Minister Ali Akbar Salehi as saying.

Salehi has suggested holding the next round in Cairo but said the powers wanted another venue. He also said that Sweden, Kazakhstan and Switzerland had offered to host the talks.

In Moscow, Russian Foreign Minister Sergei Lavrov told a news conference: "We are ready to meet at any location as soon as possible. We believe the essence of our talks is far more important (than the site), and we hope that common sense will prevail and we will stop behaving like little children."

Ashton is overseeing diplomatic contacts on behalf of the powers hoping to persuade Tehran to stop higher-grade uranium enrichment and accept stricter U.N. inspections in return for civilian nuclear cooperation and relief from U.N. sanctions.

IRAN DENIES FORDOW BLAST

Reuters has been unable to verify reports since Friday of an explosion early last week at the underground Fordow bunker that some Israeli and Western media said wrought heavy damage.

"The false news of an explosion at Fordow is Western propaganda ahead of nuclear negotiations to influence their process and outcome," IRNA quoted deputy Iranian nuclear energy agency chief Saeed Shamseddin Bar Broudi as saying.

In late 2011 the plant at Fordow began producing uranium enriched to 20 percent fissile purity, well above the 3.5 percent level normally needed for nuclear power stations.

While such higher-grade enrichment remains nominally far below the 90 percent level required for an atomic bomb, nuclear proliferation experts say the 20 percent threshold represents the bulk of the time and effort involved in yielding weapons-grade material - if that were Iran's goal.

Tehran says its enhanced enrichment is to make fuel for a research reactor that produces isotopes for medical care.

Diplomats in Vienna, where the U.N. nuclear watchdog agency is based, said on Monday they had no knowledge of any incident at Fordow but were looking into the reports.

"I have heard and seen various reports but am unable to authenticate them," a senior diplomat in Vienna told Reuters.

The International Atomic Energy Agency, which regularly inspects declared Iranian nuclear sites including Fordow, had no immediate comment on the issue.

Iran has accused Israel and the United States of trying to sabotage its nuclear program with cyber attacks and assassinations of its nuclear scientists. Washington has denied any role in the killings while Israel has declined to comment.

Iran successfully launches monkey into space: report
Jan 28th 2013, 11:41

DUBAI | Mon Jan 28, 2013 6:41am EST

DUBAI (Reuters) - Iran has successfully launched a live monkey into space, the state news agency IRNA said on Monday, touting it as an advance in a missile and space program that has alarmed the West and Israel.

There was no independent confirmation of the report, which quoted a defense ministry statement. It said the launch coincided "with the days of" the Prophet Mohammad's birthday last week but gave no date.

IRNA said the monkey was sent into space on a Kavoshgar rocket. The rocket reached a height of more than 120 km (75 miles) and "returned its shipment intact", IRNA reported.

The Islamic Republic's state-run, English-language Press TV said the monkey was retrieved alive.

Iran announced plans in 2011 to send a monkey into space, but that attempt was reported to have failed.

Western powers are concerned that the long-range ballistic technology used to propel Iranian satellites into orbit could be used to launch nuclear warheads. Tehran denies such suggestions and says its nuclear activity is for peaceful energy only.

Andean glaciers melting at "unprecedented" rates: study
Jan 24th 2013, 16:17

LIMA | Thu Jan 24, 2013 11:17am EST

LIMA (Reuters) - Climate change has shrunk Andean glaciers between 30 and 50 percent since the 1970s and could melt many of them away altogether in coming years, according to a study published on Tuesday in the journal The Cryosphere.

Andean glaciers, a vital source of fresh water for tens of millions of South Americans, are retreating at their fastest rates in more than 300 years, according to the most comprehensive review of Andean ice loss so far.

The study included data on about half of all Andean glaciers in South America, and blamed the ice loss on an average temperature spike of 0.7 degree Celsius (1.26 degrees Fahrenheit) over the past 70 years.

"Glacier retreat in the tropical Andes over the last three decades is unprecedented," said Antoine Rabatel, the lead author of the study and a scientist with the Laboratory for Glaciology and Environmental Geophysics in Grenoble, France.

The researchers also warned that future warming could totally wipe out the smaller glaciers found at lower altitudes that store and release fresh water for downstream communities.

"This is a serious concern because a large proportion of the population lives in arid regions to the west of the Andes," said Rabatel.

The Chacaltaya glacier in the Bolivian Andes, once a ski resort, has already disappeared completely, according to some scientists.

BOSTON | Thu Jan 24, 2013 12:13am EST

BOSTON (Reuters) - After spending the weekend reading blog posts claiming that he was seeking an "extremely adventurous female human" to bear a cloned Neanderthal baby - which was news to him - Harvard geneticist George Church said it may be time for society to give some thought to scientific literacy.

Church became the subject of dozens of posts and tabloid newspaper articles calling him a "mad scientist" after giving an interview to the German magazine Der Spiegel.

In the interview, Church discussed the technical challenges scientists would face if they tried to clone a Neanderthal, though neither he nor the Der Spiegel article, which was presented as a question and answer exchange, said he intended to do so.

"Harvard professor seeks mother for cloned cave baby," read one headline, on the website of London's Daily Mail.

But Church explained on Wednesday that he was simply theorizing.

Still, the readiness of bloggers, journalists and readers to believe he was preparing an attempt to clone a Neanderthal, a species closely related to modern humans that went extinct some 30,000 years ago, led Church to ponder scientific literacy.

"The public should be able to detect cases where things seem implausible," Church said in an interview at his office at Harvard Medical School in Boston. "Everybody's fib detector should have been going off. They should have said, ‘What? Who would believe this?' ... This really indicates that we should have scientific literacy."

Despite the spate of articles comparing him to the character in the book and movie "Jurassic Park" who attempts to open a theme park filled with living dinosaurs, Church said he plans to continue speaking publicly about his research, which focuses on using genes to treat and prevent disease.

Given the number of policy debates driven by science - from how to address climate change, to space exploration, to public health concerns - scientists should not back away from talking to the media, Church said.

"We really should get the public of the entire world to be able to detect the difference between a fact and a complete fantasy that has been created by the Internet," he said.

In the Der Spiegel article, which Church said reported his words accurately, and his recent book "Regenesis: How Synthetic Biology Will Reinvent Nature and Ourselves," Church theorized that studying cloned Neanderthals could help scientists better understand how the human mind works. Scientists have already extracted DNA from Neanderthal bones.

But such experiments would pose a host of ethical concerns - including how many Neanderthals would be created and whether they would be treated as mere study subjects or as beings with their own rights, Church said.

"I do want to connect the public to science because there are so many decisions to be made if the way they learn it, if they learn it faster by talking about Neanderthals than they did by getting rote learning in high school, that's great," he said.

Adelie penguins: cool, efficient killing machines
Jan 24th 2013, 05:33

TOKYO | Wed Jan 23, 2013 11:34pm EST

TOKYO (Reuters) - Fish of the Antarctic, be very afraid. There's an unlikely stealth predator on the loose - Adelie penguins.

Forget their ungainly waddling on land or comical bobbing at the ocean's surface. As soon as these penguins dive into the icy Antarctic ocean, they become calculating, efficient killing machines, say Japanese researchers.

"You could say the penguins have an amazing stealth mode," said Yuuki Watanabe, a researcher at Japan's National Institute of Polar Research. "They're great at sneaking up on their prey and taking them unaware."

Watanabe this week released footage recorded in December 2010 showing a bird's eye view of a hunt for fish and small crustaceans called krill, captured using a small video camera strapped to the backs of more than a dozen penguins.

"The krill wiggle their bodies about, they clearly make an attempt to swim off at full speed and escape," Watanabe said of his findings, published in the U.S.-based Proceedings of the National Academy of Sciences this week.

"But that doesn't make the slightest difference to the penguins. They just gobble up the krill that are trying to get away and swallow them whole."

Using the "penguin cams," which were set to automatically switch on when a penguin entered the water and shoot for 90 minutes, Watanabe and his team were able to capture the secrets of penguins on the hunt.

Additional information came from two accelerometers strapped to each bird that measured its head and body movements to calculate how fast it devoured its prey.

"We didn't really know if the penguins caught krill one-by-one. I'd thought that maybe they just got into their stomachs when they were after some other prey," Watanabe said. "But when we saw the footage it turned out the penguins were doing just that, eating these tiny little creatures one after the other."

Not only that, the penguins didn't swim randomly but hung poised on the edge of the ice until a thick swarm neared, then swooped into the water. Footage showed a penguin zooming under the ice and then deeper, its head snapping rapidly up as it fed.

The krill killing-rate was both fast and efficient. The penguins gobbled an average of two krill per second, consuming about 244 krill in roughly 90 minutes.

"I was so happy when I got the footage of a penguin going straight into a swarm of krill and gorging itself," Watanabe said.

Penguin research completed, Watanabe now aims to repeat the same exercise with sharks.

CAPE CANAVERAL, Fla., Jan 22 - A team of entrepreneurs and engineers unveiled plans on Tuesday for a space mining company that would tap nearby asteroids for raw materials to fuel satellites and manufacture components in orbit.

Deep Space Industries, based in Santa Monica, California, said its inaugural mission is targeted for 2015, when it would send a small hitchhiker spacecraft called "Firefly" on a six-month expedition to survey an as-yet-unidentified asteroid.

The 55-pound (25-kg) satellite, about the size of a laptop computer, would be launched as a secondary payload aboard a commercial rocket carrying a communications satellite or other robotic probe.

About 1,000 small asteroids relatively close to Earth are discovered every year. Most, if not all, are believed to contain water and gases, such as methane, which can be turned into fuel, as well as metals, such as nickel, which can be used in three-dimensional printers to manufacture components, David Gump, chief executive of Deep Space Industries, said.

Gump is a co-founder of three previous space and technology start-ups, including Astrobotic Technology, which is focused on exploration and development of lunar resources.

"There is really nothing in the business plan that Deep Space Industries is pursuing that cannot be done with technology research already accomplished in laboratories across the planet," said John Mankins, a former NASA Jet Propulsion Laboratory manager who is the start-up company's chief technical officer.

"The technology may not have been used in space for the exact purposes that we propose, but the fundamental technologies are really at hand," Mankins said.

Company officials, who unveiled their plans at a press conference at the Museum of Flying in Santa Monica, California, that was also webcast, did not comment on their financial backing except to say they were looking for investors.

Deep Space Industries is the second company to unveil plans to mine asteroids, rocky bodies of various sizes that orbit the sun. So far about 9,500 asteroids have been found in orbits that come near Earth. Small fragments of asteroids regularly pass through the planet's atmosphere, lighting up the night sky as they incinerate and occasionally surviving to become meteorites.

Last year, Planetary Resources, a Bellevue, Washington-based company backed by high-profile investors including Google executives Larry Page and Eric Schmidt and advisers like filmmaker James Cameron, announced a program that would begin with small, low-cost telescopes to scout for potentially lucrative asteroids.

Firefly, as well as a follow-on line of planned asteroid sample-return satellites called Dragonfly, would be based on miniature research spacecraft known as CubeSats that are built from commercially available, off-the-shelf electronic components.

The cost of a Firefly mission would be about $20 million, half of which the company expects will come from government and research institute contracts and half from corporate advertising, sponsorships and other marketing ventures, said Gump.

The follow-on Dragonfly missions, scheduled to begin in 2016, would entail returning 50 to 100 pounds (23 to 45 kg) of material from select, high-value asteroids, an endeavor that would take two to three years.

In addition to selling samples, Deep Space Industries wants to grind up some of the material, extract metals and other valuable commodities and develop the technology to produce fuel and components, such as solar cells, in space.

The company said it has a patent pending on a three-dimensional printer called a "Microgravity Foundry" that uses lasers to deposit nickel in precise patterns in zero gravity.

On Earth, similar printers produce three-dimensional components by depositing layers of nickel metal powder. The process is somewhat like the buildup of ink on paper in a traditional ink jet printer.

Gump said the patent was filed within the past 18 months and is not yet listed in publicly accessible databases.

The ultimate goal is to build a fleet of robotic ships to extract resources for fuel and to mine valuable minerals from asteroids.

"We're at an early stage," said Gump. "It'll probably be 2019 or 2020 before we'll have commercial quantities of propellant for sale."

LAS VEGAS | Wed Jan 16, 2013 7:06pm EST

LAS VEGAS (Reuters) - A low-cost space dwelling that inflates like a balloon in orbit will be tested aboard the International Space Station, opening the door for commercial leases of future free-flying outposts and deep-space astronaut habitats for NASA.

The Bigelow Expandable Activity Module, nicknamed BEAM, will be the third orbital prototype developed and flown by privately owned Bigelow Aerospace.

The Las Vegas-based company, founded in 1999 by Budget Suites of America hotel chain owner Robert Bigelow, currently operates two small unmanned experimental habitats called Genesis 1, launched in 2006, and Genesis 2, which followed a year later.

BEAM, about 13 feet long and 10.5 feet in diameter when inflated, is scheduled for launch in mid-2015 aboard a Space Exploration Technologies' Dragon cargo ship, said Mike Gold, director of operations for Bigelow Aerospace.

"It will be the first expandable habitat module ever constructed for human occupancy," Gold said.

A successful test flight on the space station would be a stepping stone for planned Bigelow-staffed orbiting outposts that the company plans to lease to research organizations, businesses and wealthy individuals wishing to vacation in orbit.

Bigelow has invested about $250 million in inflatable habitation modules so far. It has preliminary agreements with seven non-U.S. space and research agencies in the United Kingdom, the Netherlands, Australia, Singapore, Japan, Sweden and the United Arab Emirates.

"The value to me personally and to our company is doing a project with NASA," Robert Bigelow said. "This is our first opportunity to do that. We do have other ambitions."

NASA, which will pay Bigelow Aerospace $17.8 million for the BEAM habitat, also is interested in the technology to house crew during future expeditions beyond the space station, a $100 billion research complex that flies about 250 miles above Earth.

"Whether you're going to the surface of the moon or even Mars, the benefits of expandable habitats are critical for any exploration mission," Gold said.

The lightweight, soft-skinned inflatable, made of materials similar to Kevlar, has several advantages over traditional metallic space dwellings. BEAM, for example, weighs about 3,000 pounds (1,361 kg), less than a third of traditional, similarly sized space modules, so it can be launched for a fraction of the cost.

RADIATION EVENTS

It also offers a potentially safer radiation environment than metal structures, which can produce body-piercing secondary heavy particles during solar storms and other cosmic radiation events.

The U.S. space agency studied inflatable space habitats for humans in the 1990s under a NASA program called TransHab. The tests included blasting a model structure with bullet-like projectiles to see how well it would withstand micro meteoroid and orbital debris hits. The material proved space-worthy, though budget and political issues prompted the project's cancellation in 2000.

Bigelow later licensed the technology from NASA and spent millions of dollars more to develop it.

"It's one of our classical roles to advance technology so the private sector can utilize it. In this case, we're going to be able to benefit from it again," said NASA deputy administrator Lori Garver.

BEAM will be attached to the station's Tranquility connecting node and inflated with pressurized air to form a rigid, cylinder-shaped, balloon-like dwelling.

Garver said there are no firm plans for what the station's six live-aboard crew members will do with their spare room.

Initially, NASA and Bigelow are interested in getting information about how the structure withstands radiation and maintains a stable temperature in orbit, and also whether the fabric mildews or becomes a place where contaminants in the station's air collects.

Beyond the test flight, Bigelow's commercial business is dependent on the development of space taxis to fly company personnel and guests into orbit. NASA likewise is looking to the private sector to fly its astronauts to and from the space station, a service now solely provided by Russia at a cost of more than $60 million per person.

NASA is investing in three companies - Boeing Co, Space Exploration Technologies, also known as SpaceX, and Sierra Nevada Corp - in hopes of having at least one space transportation system ready to fly before the end of 2017. The space station, a project of 15 nations, currently is funded through 2020.

Bigelow has agreements with Boeing and SpaceX for launch services, if and when they become available. SpaceX plans a test launch with company astronauts before the end of 2015, and Boeing's first piloted flight is pegged for 2016.
