Space could leave you blind, and scientists say they've finally figured out why
(Science Alert) A mysterious syndrome has been impairing astronauts’ vision on the International Space Station, causing untreatable nearsightedness that lingers for months even after they’ve returned to Earth.
The problem is so bad that two-thirds of astronauts report having deteriorated eyesight after spending time in orbit. Now scientists say they finally have some answers - and it’s not looking good for our prospects of getting to Mars.
"Nobody’s gone two years with exposure to this, and the concern is that we’d have loss of vision," Dorit Donoviel from the US National Space Biomedical Research Institute told The Guardian. "That is catastrophic for an astronaut."
Earlier this year, NASA reported that something in space has been messing with its astronauts’ perfect eyesight, causing long-term impairment to their quality of vision.
Astronaut Scott Kelly, whose exceptional vision was part of the reason he was selected to be America’s first astronaut to spend a full year in space, says he's been forced to wear reading glasses since coming home.
John Phillips, who spent time on the International Space Station (ISS) in 2005, brought his sudden bouts of blurry vision home with him, and during his post-flight physical, NASA confirmed that his vision had gone from 20/20 to 20/100 in just six months.
NASA suspected that the condition - called visual impairment inter cranial pressure syndrome, or VIIP - was caused by the lack of gravity in space.
The hypothesis was that the microgravity of the ISS was building up pressure in astronauts’ heads, causing roughly 2 litres of vascular fluid to shift towards their brains.
They say that pressure was responsible for the flattening of eyeballs and inflaming of optic nerves observed in returned astronauts.
"On Earth, gravity pulls bodily fluids down toward the feet. That doesn’t happen in space, and it is thought that extra fluid in the skull increases pressure on the brain and the back of the eye," Shayla Love reported for The Washington Post.
Now, a team from the University of Miami has conducted the first study to actually test this idea, and found that something else has been causing vision problems in astronauts.
The researchers compared before and after brain scans from seven astronauts who had spent many months in the ISS, and compared them to nine astronauts who had just made short trips to and from the US space shuttle, which was decommissioned in 2011.
The one big difference between the two was that the long-duration astronauts had significantly more cerebrospinal fluid (CSF) in their brains than the short-trip astronauts, and the researchers say this - not vascular fluid - is the cause of the vision loss...(continued)

These colors are not what Mercury would look like to the human eye, but rather the colours enhance the chemical, mineralogical, and physical differences between the rocks that make up Mercury's surface, according to Nasa. The MESSENGER spacecraft that made surprising discoveries of ice and other materials on Mercury will make a crash landing into the planet around April 30, scientists said.

NASA builds a time-machine telescope 100 times as powerful as the Hubble
These parts — gold-covered mirrors, tennis-court-size sun shields, delicate infrared cameras — are slowly being put together to become the James Webb Space Telescope.
Astronomers are hoping that the Webb will be able to collect light that is very far away from us and is moving still farther away. The universe has been expanding ever since the big bang got it started, but scientists reckon that if the telescope is powerful enough, they just might be able to see the birth of the first galaxies, some 13.5 billion years ago.
“This is similar to archaeology,” says Harvard astrophysicist Avi Loeb, who helped plan Webb’s science mission. “We are digging deep into the universe. But as the sources of light become fainter and farther away, you need a big telescope like the James Webb.”
Named for a former NASA director, the 21-foot-diameter Webb telescope will be 100 times as powerful as the Hubble Space Telescope, which was launched in 1990. Although Hubble wasn’t the first space telescope, its images of far-off objects have dazzled the public and led to breakthroughs in astrophysics, such as determining how fast the universe is expanding.
The Webb will be both bigger and located in a darker part of space than Hubble, enabling it to capture images from the faintest galaxies. Four infrared cameras will capture light that is moving away from us very quickly and that has shifted from the visible to the infrared spectrum, described as red-shifted. The advantage of using infrared light is that it is not blocked by clouds of gas and dust that may lie between the telescope and the light. Webb’s mirrors are covered in a thin layer of gold that absorbs blue light but reflects yellow and red visible light, and its cameras will detect infrared light and a small part of the visible spectrum. As objects move away from us, the wavelength of their light shifts from visible light to infrared light. That’s why the Webb’s infrared cameras will be able to see things that are both far away and moving away from us... (continued)

Lumen Fidei: The Science of Creation and a Tale of Two Priests
By Father Gordon J. MacRae @ These Stone Walls
FATHER GEORGES LEMAITRE
Perhaps the best example in modern science is one I tackled in my first “science post” on These Stone Walls three years ago, and used again as an encore post last week. It was about the Belgian priest, mathematician and physicist, Father Georges Lemaitre, originator of the Big Bang theory and the man who changed the mind of Albert Einstein on the true origin of the created Universe. In a brief disclaimer at the beginning of that post, I asked TSW readers to “indulge me in this few minutes of science and history.” Well, please do so again, for it’s a necessary prelude to this post. What follows will make much more sense if you’ve had another look at “A Day Without Yesterday: Father Georges Lemaitre and The Big Bang.”
At the very end of that post, there is a photograph of Father Lemaitre with Albert Einstein who once told Father Lemaitre in response to his theory about the Big Bang, “Your math is perfect, but your physics is abominable.” Six years later, in 1933, Einstein declared that his own “Cosmological Constant” – his theory that the Universe always existed – was his greatest error, and he called Father Lemaitre’s work “the most beautiful and satisfactory explanation of creation I have ever heard.” For Einstein to use the “C” word – Creation – was a pivotal moment in modern science.
The story of Fr. Lemaitre’s role in modern cosmology was often stifled by science because he was a Catholic priest. Today, it is told well in How It Began: A Time Traveler’s Guide to the Universe by Chris Impey (Norton 2012), a professor of astronomy at the University of Arizona in Tucson.
Something astonishing happened after I wrote “A Day Without Yesterday.”
I first mentioned my friend, Pierre Matthews, a TSW reader from Belgium who has visited me several times in prison, in my post, “Saints Alive! Padre Pio and the Stigmata.” It described Pierre’s encounter with Padre Pio when he visited San Giovanni Rotondo as a teenager in 1954. It was like a bolt of lightning to know that there are but two degrees of separation between me and Saint Pio of Pietrelcina, one of the patrons of These Stone Walls. Pierre is also Pornchai Moontri’s Godfather... (continued)

Mars colonists sought for exhibition

By GABRIELLE LEVY, UPI.com
Would you like to go live on Mars?
A Dutch company called Mars One has announced plans to create the first human settlement on the Red Planet in just 10 years.
Mars One plans to pick travelers to submit to a full-time training program that will conclude with a one-way ticket to Mars, where a prepared colony will be waiting.
Prospective colonists must be at least 18 years old, and the Mars One team says qualities such as resiliency, adaptability, creativity, resourcefulness and curiosity will be given high priority. All necessary skills for Mars survival will be taught to the colonists over the next decade as they prepare full-time to blast into space--and history.
Mars One founders Bas Landsorp and Arno Wielders, entrepreneurs with ties to technology and space industries, said they plan to send probes and rovers as early as 2016 to prepare the planet for human habitation.
And--no surprise here--they plan to fund the mission through the wonders of Reality television.
According to the Los Angeles Times, Space X founder Elon Musk is also eyeing plans to populate Mars, offering aspiring Martians berth for the low low price of half a million dollars.

SpaceX's Elon Musk: Your ticket to Mars? Half a million dollars
November 26, 2012 | By Deborah Netburn(Los Angeles Times) SpaceX founder and billionaire Elon Musk is laying out his plans for a colony on Mars, and they are specific.
Musk has already mapped out an approximate number of people he imagines living in the Mars colony (80,000), as well as how much a ticket to Mars might cost--$500,000.
But first, he said, SpaceX has to design what he calls a "rapid and reusable" rocket that can land vertically. "That is the pivotal step to achieving a colony on Mars," he told an audience at the Royal Aeronautical Society in London last week.
If SpaceX or another company can't come up with a rocket that can be reused and refueled (like we reuse airplanes), then he said colonizing Mars would be prohibitively expensive.
Musk described creating a rocket that could shuttle between Mars and the Earth as "possible, but quite difficult."
But that hasn't stopped him from mapping out a vision of how a colony on Mars might grow. The first step, of course, is getting a manned mission to Mars, which Musk said he thinks SpaceX can do in 10 to 15 years.
Next, he envisions sending 10 people to the Red Planet, along with supplies to build transparent domes, Space.com reports. If the domes are pressurized with the CO2 in Mars' atmosphere, the colonists could grow Earth crops in the soil on Mars.
As the colony became more self-sufficient, space on the rocket could be filled with people rather than supplies.
And those numbers Musk tossed out are not random. He arrived at 80,000 colonists by estimating that by the time a Mars colony is a reality there will be 8 billion people on Earth. Musk said he thinks 1 in 100,000 people will be ready and willing to take the journey to Mars. As for the $500,000 ticket--he said that while it's a lot of money, it is a sum of money that someone who has worked hard and saved carefully might be able to afford.
And as to whether the American taxpayer should contribute to a colony on Mars, Musk says yes. A colony on another planet is life insurance for life collectively, he said during his talk. He added that it would be a fun adventure to watch, even if you aren't planning on going yourself.
If you'd like to see the talk for yourself, check out the video below.

Hubble Goes to the eXtreme to Assemble Farthest-Ever View of the Universe

(NASA) Like photographers assembling a portfolio of best shots, astronomers have assembled a new, improved portrait of mankind's deepest-ever view of the universe.
Called the eXtreme Deep Field, or XDF, the photo was assembled by combining 10 years of NASA Hubble Space Telescope photographs taken of a patch of sky at the center of the original Hubble Ultra Deep Field. The XDF is a small fraction of the angular diameter of the full moon.
The Hubble Ultra Deep Field is an image of a small area of space in the constellation Fornax, created using Hubble Space Telescope data from 2003 and 2004. By collecting faint light over many hours of observation, it revealed thousands of galaxies, both nearby and very distant, making it the deepest image of the universe ever taken at that time.
The new full-color XDF image is even more sensitive, and contains about 5,500 galaxies even within its smaller field of view. The faintest galaxies are one ten-billionth the brightness of what the human eye can see...

Strange Mystery Spheres on Mars Baffle Scientists

(Space.com) A strange picture of odd, spherical rock formations on Mars from NASA's Opportunity rover has scientists scratching their heads over what exactly they're looking at.
The new Mars photo by Opportunity shows a close-up of a rock outcrop called Kirkwood covered in blister-like bumps that mission scientists can't yet explain. At first blush, the formations appear similar to so-called Martian "blueberries" — iron-rich spherical formations first seen by Opportunity in 2004 — but they actually differ in several key ways, scientist said.
"This is one of the most extraordinary pictures from the whole mission," said rover mission principal investigator Steve Squyres of Cornell University in Ithaca, N.Y., in a statement. "Kirkwood is chock full of a dense accumulation of these small spherical objects. Of course, we immediately thought of the blueberries, but this is something different. We never have seen such a dense accumulation of spherules in a rock outcrop on Mars."

Neil Armstrong dies at 82
The modest man who entranced and awed people on Earth has died. He was 82.
Armstrong died Saturday following complications resulting from cardiovascular procedures, a statement from his family said. It didn't say where he died.
Armstrong commanded the Apollo 11 spacecraft that landed on the moon July 20, 1969, capping the most daring of the 20th century's scientific expeditions. His first words after setting foot on the surface are etched in history books and in the memories of those who heard them in a live broadcast.
"That's one small step for man, one giant leap for mankind," Armstrong said.
In those first few moments on the moon, during the climax of a heated space race with the then-Soviet Union, Armstrong stopped in what he called "a tender moment" and left a patch to commemorate NASA astronauts and Soviet cosmonauts who had died in action.
"It was special and memorable, but it was only instantaneous because there was work to do," Armstrong told an Australian television interviewer this year.
Armstrong and Buzz Aldrin spent nearly three hours walking on the lunar surface, collecting samples, conducting experiments and taking photographs.
"The sights were simply magnificent, beyond any visual experience that I had ever been exposed to," Armstrong once said.
The moonwalk marked America's victory in the Cold War space race that began Oct. 4, 1957, with the launch of the Soviet Union's Sputnik 1, a satellite that sent shock waves around the world.
An estimated 600 million people -- a fifth of the world's population -- watched and listened to the moon landing, the largest audience for any single event in history.
Parents huddled with their children in front of the family television, mesmerized. Farmers abandoned their nightly milking duties, and motorists pulled off the highway and checked into motels just to watch on TV.
Although he had been a Navy fighter pilot, a test pilot for NASA's forerunner and an astronaut, Armstrong never allowed himself to be caught up in the celebrity and glamour of the space program.
"I am, and ever will be, a white socks, pocket protector, nerdy engineer," he said in February 2000 in one of his rare public appearances. "And I take a substantial amount of pride in the accomplishments of my profession."
A man who kept away from cameras, Armstrong went public in 2010 with his concerns about President Barack Obama's space policy that shifted attention away from a return to the moon and emphasized private companies developing spaceships. He testified before Congress, and in an email to The Associated Press he said he had "substantial reservations."
NASA chief Charles Bolden recalled Armstrong's grace and humility in a statement Saturday.
"As long as there are history books, Neil Armstrong will be included in them, remembered for taking humankind's first small step on a world beyond our own," Bolden said.
Armstrong's modesty and self-effacing manner never faded.
When he appeared in Dayton, Ohio, in 2003 to help celebrate the 100th anniversary of powered flight, he bounded onto a stage before 10,000 people. But he spoke for only a few seconds, did not mention the moon and quickly ducked out of the spotlight.
He later joined former astronaut and Sen. John Glenn to lay wreaths on the graves of airplane inventors Wilbur and Orville Wright. Glenn introduced Armstrong and noted it was 34 years to the day that Armstrong had walked on the moon.
"Thank you, John. Thirty-four years?" Armstrong quipped, as if he hadn't given it a thought.
At another joint appearance, the two embraced and Glenn commented: "To this day, he's the one person on Earth, I'm truly, truly envious of."
Armstrong's moonwalk capped a series of accomplishments that included piloting the X-15 rocket plane and making the first space docking during the Gemini 8 mission, which included a successful emergency splashdown.
In the years afterward, Armstrong retreated to the quiet of the classroom and his Ohio farm. Aldrin said in his book "Men from Earth" that Armstrong was one of the quietest, most private men he had ever met.
In the Australian interview, Armstrong acknowledged that "now and then I miss the excitement about being in the cockpit of an airplane and doing new things."
At the time of the flight's 40th anniversary, Armstrong again was low-key, telling a gathering that the space race was "the ultimate peaceful competition: USA versus U.S.S.R. It did allow both sides to take the high road, with the objectives of science and learning and exploration."
Glenn, who went through jungle training in Panama with Armstrong as part of the astronaut program, described him as "exceptionally brilliant" with technical matters but "rather retiring, doesn't like to be thrust into the limelight much."
Glenn told CNN on Saturday that Armstrong had had a number of close calls in his career, including during the moon landing, when they had less than a minute of fuel remaining on arrival.
"He was a good friend and he'll be missed," Glenn told the network.
Derek Elliott, curator of the Smithsonian Institution's U.S. Air and Space Museum from 1982 to 1992, said the moonwalk probably marked the high point of space exploration.
"The fact that we were able to see it and be a part of it means that we are in our own way witnesses to history," he said.
The 1969 landing met an audacious deadline that President John F. Kennedy had set in May 1961, shortly after Alan Shepard became the first American in space with a 15-minute suborbital flight. Soviet cosmonaut Yuri A. Gagarin had orbited the Earth and beaten the U.S. into space the previous month.
"I believe this nation should commit itself to achieving the goal, before the decade is out, of landing a man on the moon and returning him safely to Earth," Kennedy had said. "No single space project in this period will be more impressive to mankind, or more important to the long-range exploration of space; and none will be so difficult or expensive to accomplish."
The end-of-decade goal was met with more than five months to spare. "Houston: Tranquility Base here," Armstrong radioed after the spacecraft settled onto the moon. "The Eagle has landed."
"Roger, Tranquility," the Houston staffer radioed back. "We copy you on the ground. You've got a bunch of guys about to turn blue. We're breathing again. Thanks a lot."
The third astronaut on the mission, Michael Collins, circled the moon in the mother ship Columbia while Armstrong and Aldrin went to the moon's surface.
Collins told NASA on Saturday that he will miss Armstrong terribly, spokesman Bob Jacobs tweeted.
In all, 12 American astronauts walked on the moon between 1969 and the last moon mission in 1972.
For Americans, reaching the moon provided uplift and respite from the Vietnam War. The landing occurred as organizers were preparing for Woodstock, the legendary rock festival on a farm in New York.
Armstrong was born Aug. 5, 1930, on a farm in Ohio. He took his first airplane ride at age 6 and developed a fascination with aviation that prompted him to build model airplanes and conduct experiments in a homemade wind tunnel. He was licensed to fly at 16, before he got his driver's license.
Armstrong enrolled in Purdue University to study aeronautical engineering but was called to duty with the U.S. Navy in 1949 and flew 78 combat missions in Korea. After the war, Armstrong finished his degree and later earned a master's degree in aerospace engineering from the University of Southern California. He became a test pilot with what evolved into the National Aeronautics and Space Administration, flying more than 200 kinds of aircraft from gliders to jets.
Armstrong was accepted into NASA's second astronaut class in 1962 -- the first, including Glenn, was chosen in 1959 -- and commanded the Gemini 8 mission in 1966. After the first space docking, he brought the capsule back in an emergency landing in the Pacific Ocean when a wildly firing thruster kicked it out of orbit.
Armstrong was backup commander for the historic Apollo 8 mission at Christmastime in 1968. In that flight, Commander Frank Borman, and Jim Lovell and Bill Anders circled the moon 10 times, and paving the way for the lunar landing seven months later.
Aldrin said he and Armstrong were not prone to free exchanges of sentiment.
"But there was that moment on the moon, a brief moment, in which we sort of looked at each other and slapped each other on the shoulder ... and said, `We made it. Good show,' or something like that," Aldrin said.
In Wapakoneta, media and souvenir frenzy was swirling around the home of Armstrong's parents.
"You couldn't see the house for the news media," recalled John Zwez, former manager of the Neil Armstrong Air and Space Museum. "People were pulling grass out of their front yard."
Armstrong, Aldrin and Collins were given ticker tape parades in New York, Chicago and Los Angeles and later made a 22-nation world tour. A homecoming in Wapakoneta drew 50,000 people to the city of 9,000.
In 1970, Armstrong was appointed deputy associate administrator for aeronautics at NASA but left the following year to teach aerospace engineering at the University of Cincinnati.
He remained there until 1979 and during that time bought a farm, where he raised cattle and corn. He stayed out of public view, accepting few requests for interviews or speeches.
"He didn't give interviews, but he wasn't a strange person or hard to talk to," said Ron Huston, a colleague at the University of Cincinnati. "He just didn't like being a novelty."
In February 2000, when he agreed to announce the top 20 engineering achievements of the 20th century as voted by the National Academy of Engineering, Armstrong said there was one disappointment relating to his moonwalk.
"I can honestly say -- and it's a big surprise to me -- that I have never had a dream about being on the moon," he said.
Armstrong married Carol Knight in 1999. He had two adult sons from a previous marriage.
His family's statement Saturday made a simple request for anyone who wanted to remember him:
"Honor his example of service, accomplishment and modesty, and the next time you walk outside on a clear night and see the moon smiling down at you, think of Neil Armstrong and give him a wink."

What Happens When You Shoot a Gun in Space?
From Life's Little Mysteries:
By Natalie Wolchover
Fires can't burn in the oxygen-free vacuum of space, but guns can shoot. Modern ammunition contains its own oxidizer, a chemical that will trigger the explosion of gunpowder, and thus the firing of a bullet, wherever you are in the universe. No atmospheric oxygen required.
The only difference between pulling the trigger on Earth and in space is the shape of the resulting smoke trail. In space, "it would be an expanding sphere of smoke from the tip of the barrel," said Peter Schultz an astronomer at Brown University who researches impact craters.
The possibility of gunfire in space allows for all kinds of absurd scenarios.
Imagine you're floating freely in the vacuum between galaxies — just you, your gun and a single bullet. You have two options. You either can spend all of eternity trying to figure out how you got there, or you can shoot the damn cosmos.
If you do the latter, Newton's third law dictates that the force exerted on the bullet will impart an equal and opposite force on the gun, and, because you're holding the gun, you. With very few intergalactic atoms against which to brace yourself, you'll start moving backward (not that you’d have any way of knowing). If the bullet leaves the gun barrel at 1,000 meters per second, you — because you're much more massive than it is — will head the other way at only a few centimeters per second.
Once shot, the bullet will keep going, quite literally, forever. "The bullet will never stop, because the universe is expanding faster than the bullet can catch up with any serious amount of mass" to slow it down, said Matija Cuk, an astronomer with joint appointments at Harvard University and the SETI Institute. (If the universe weren't expanding, then the one or two atoms per cubic centimeter encountered by the bullet in the near-vacuum of space would bring it to a standstill after 10 million light-years.)
Getting down to details, the universe expands at a rate of 73 kilometers per second per megaparsec (about 3 million light-years, or the average distance between galaxies). By Cuk's calculations, this means matter that is 40,000 to 50,000 light-years away from the bullet would move away from it at about the same speed at which it is travelling, and would thus be forever out of reach. In the entire future of the universe, the bullet will catch up only to atoms that are less than 40,000 or so light-years from the chamber of your gun.
Speaking of you, you'll be bobbing through space forever, too. [Album: Visualizations of Infinity]
Shooting giants from the hip
Guns do actually get carried to space, though not quite to the void between galaxies. For decades, the standard survival pack for Russian cosmonauts has included a gun. Until recently, it wasn't just any gun, but "a deluxe all-in-one weapon with three barrels and a folding stock that doubles as a shovel and contains a swing-out machete," according to space historian James Oberg...

Former NASA Director Says Muslim Outreach Push 'Deeply Flawed'
By Judson Berger
(Fox News) The former head of NASA on Tuesday described as "deeply flawed" the idea that the space exploration agency's priority should be outreach to Muslim countries, after current Administrator Charles Bolden made that assertion in an interview last month.
Bolden created a firestorm after telling Al Jazeera last month that President Obama told him before he took the job that he wanted him to do three things: inspire children to learn math and science, expand international relationships and "perhaps foremost, he wanted me to find a way to reach out to the Muslim world and engage much more with dominantly Muslim nations to help them feel good about their historic contribution to science ... and math
and engineering."
Officials from the White House and NASA on Tuesday stood by Bolden's statement that part of his mission is to improve relations with Muslim countries -- though NASA backed off the claim that such international diplomacy is Bolden's "foremost" responsibility.
Griffin said Tuesday that collaboration with other countries, including Muslim nations, is welcome and should be encouraged -- but that it would be a mistake to prioritize that over NASA's "fundamental mission" of space exploration.
"If by doing great things, people are inspired, well then that's wonderful," Griffin said. "If you get it in the wrong order ... it becomes an empty shell."
Griffin added: "That is exactly what is in danger of happening."
He also said that while welcome, Muslim-nation cooperation is not vital for U.S. advancements in space exploration.
"There is no technology they have that we need," Griffin said.
The former administrator stressed that any criticism should be directed at Obama, not Bolden, since NASA merely carries out policy.
The White House stood by Bolden on Tuesday. Spokesman Nick Shapiro said in a written statement to FoxNews.com that Obama "wants NASA to engage with the world's best scientists and engineers as we work together to push the boundaries of exploration.
"Meeting that mandate requires NASA to partner with countries around the world like Russia and Japan, as well as collaboration with Israel and with many Muslim-majority countries. The space race began as a global competition, but, today, it is a global collaboration," he said.
Bob Jacobs, NASA's assistant administrator for public affairs, echoed that point. However, he said that Bolden was speaking of priorities when it came to "outreach" and not about NASA's primary missions of "science, aeronautics and space exploration." He said the "core mission" is exploration and that it was unfortunate Bolden's comments are now being viewed through a "partisan prism."
Though the Al Jazeera interview drew widespread attention, it wasn't the first time Bolden made the assertion.
A Feb. 16 blog in the Orlando Sentinel reported that Bolden discussed the outreach during a lecture to engineering students. As he did in the interview with Al Jazeera last month, Bolden was quoted then saying Obama told him to "find ways to reach out to dominantly Muslim countries."
He reportedly talked about the importance of helping countries establish space programs and pointed to the largest Muslim country in the world, Indonesia, as a possible partner.
"We really like Indonesia because the State Department, the Department of Education (and) other agencies in the U.S. are reaching out to Indonesia as the largest Muslim nation in the world," he said.
Bolden did not describe such outreach as his prime mission at the time.
The NASA administrator was in the Middle East last month marking the one-year anniversary since Obama delivered an address to Muslim nations in Cairo. Bolden spoke in June at the American University in Cairo, and in the interview with Al Jazeera he described space travel as an international collaboration of which Muslim nations must be a part.
"It is a matter of trying to reach out and get the best of all worlds, if you will, and there is much to be gained by drawing in the contributions that are possible from the Muslim (nations)," he said.
He held up the International Space Station as a model, praising the contributions there from the Russians and the Chinese.
However, Bolden denied the suggestion that he was on a diplomatic mission. "Not at all. It's not a diplomatic anything," he said.

Griffin disputed this point. He said the U.S. can still make those strides without international aid if it wishes, and that, "To the extent that we wish to go to Mars, we can go to Mars."
Griffin said the U.S. should in fact seek international cooperation for those missions, but that it would be "clearly false" to suggest the U.S. needs that cooperation.
Bolden has faced criticism this year for overseeing the cancellation of the agency's Constellation program, which was building new rockets and spaceships capable of returning astronauts to the moon. Stressing the importance of international cooperation in future missions, Bolden told Al Jazeera that the moon, Mars and asteroids are still planned destinations for NASA.
Fox News' Brian Wilson contributed to this report.

Congress to dump Obama NASA plan
White House plans to axe NASA's return-to-the-Moon Constellation programme and ground the Space Shuttle have sparked unified opposition from Congress, which looks determined to preserve a full spectrum of US manned spaceflight activities.
A draft Congressional bill leaked to Flight International sets out the politicians' alternate plan. It involves possibly extending Shuttle life to 2015, running competitive commercial crew and cargo programmes and continuing development of Constellation's vehicles including a heavylift rocket designed to get astronauts to the Moon in the 2020s and then Mars.
In a heated hearing on Capitol Hill, President Obama's NASA administrator Charles Bolden, a former astronaut and Shuttle commander, had to defend his deputy Lori Beth Garver and the president's plan to shift NASA's focus from missions to capabilities under the fiscal year 2011 budget request.
In the 24 February hearing of the Senate Commerce, Science and Transportation committee's science and space subcommittee one senator criticised Garver as the alleged author of the plan and budget, which the subcommittee's members described as ending all US human spaceflight efforts with its retirement of the Shuttle fleet this year and cancellation of the Constellation.
Referring to the space programme as bipartisan, subcommittee chairman senator Bill Nelson of Florida says of the opposition to the Obama plan: "I have never seen [Congress] as unified as we are now."
Much of the Congressional opposition to Obama's plan stems from estimates pegging direct job losses from cutting Constellation, Shuttle and other programmes at 30,000, including 7,000 at the Kennedy Space Center.
Bolden told the hearing that the Obama exploration goal was Mars, but during the early February budget roll-out he said that the plan's destinations would be decided by a "national conversation".

Politicians fight to keep America's moon mission alive
guardian.co.uk, Monday 1 February 2010 21.23 GMT

The announcement of an end to immediate ambitions for an American to again reach the moon, on the seventh anniversary of the Columbia space shuttle disaster, sets the stage for a furious battle in Congress over US manned space exploration.
Politicians from Florida, Texas and Alabama, three states that have lost thousands of jobs in the space industry from this year's planned retirement of the ageing shuttle fleet, promised a fight to keep the moon programme, Constellation, alive.
"They are replacing lost shuttle jobs too slowly, risking US leadership in space to China and Russia, and relying too heavily on unproven companies," said Bill Nelson, a Democratic Senator for Florida and former astronaut who flew one mission in 1986.
Michael Griffin, who resigned as Nasa chief when Obama took office, branded the plan "disastrous", likening it to Richard Nixon's cancellation of the Apollo programme in the 1970s. "It means that essentially the US has decided that they're not going to be a significant player in human space flight for the foreseeable future," he told The Washington Post...

Manned spaceship design unveiled


By Paul Rincon
Science reporter, BBC News
The first official image of a Russian-European manned spacecraft has been unveiled.
It is designed to replace the Soyuz vehicle currently in use by Russia and will allow Europe to participate directly in crew transportation.
The reusable ship was conceived to carry four people towards the Moon, rivalling the US Ares/Orion system.
Unlike previous crewed vehicles, it will use thrusters to make a soft landing when it returns to Earth.
Russian aerospace writer and graphic designer Anatoly Zak has produced artist's renderings of the new craft based on a design released by Russian manufacturer RKK Energia at the Farnborough Air Show in the UK last week.

In some respects, the capsule resembles America's next-generation spacecraft Orion. The 18-to-20-tonne Russian-European vehicle is designed to carry six crew into low-Earth orbit and four on missions to lunar orbit.
One of the most unusual features about the capsule appear to be the thrusters and landing gear on its underside. Mr Zak said it would use these engines to soften its landing on Earth after the fiery re-entry through our atmosphere.
The European Space Agency (Esa) has been talking to its Russian counterpart Roscosmos about collaborating on the Crew Space Transportation System (CSTS) since 2006.
Launcher decision
"If Esa and the Russian Space Agency reach agreement, Europe will supply the service module of that co-operative spacecraft," Mr Zak told BBC News.
This service module will use technology - such as the propulsion systems - developed for Europe's Automated Transfer Vehicle (ATV), an unmanned freighter recently sent to re-supply the International Space Station (ISS).
Russia may provide the launcher for the new manned spacecraft. This might be an entirely new vehicle, or a modification of an existing rocket.

Mr Zak said Russia was insisting in its negotiations with Europe that all future manned projects be based in Vostochny, the new cosmodrome being developed in Russia's eastern Amur region. The Russian government wants to host its first launch from that site in 2018.
At the moment, all manned Soyuz launches take place from Baikonur Cosmodrome in Kazakhstan.
Alternatively, the space agencies could opt to "man-rate" Europe's Ariane 5 launcher, which lifts off from Kourou in French Guiana. This would allow the rocket to carry humans into space.
This would involve making major modifications to Kourou spaceport, including the development of infrastructure to support a crew escape system in the event of an emergency.
It is quite possible that both launch sites would play a role in any collaborative programme, which would necessitate the lofting of cargo as well as human crew.
However, if this collaboration falls apart, Europe has another option for direct manned access to space.
Other option
In May this year, European aerospace company EADS Astrium unveiled its own model of a crewed space vehicle, described as an "evolution" of the ATV, which was built by a consortium of European companies led by Astrium.
It would combine what is essentially the avionics and propulsion end of the ATV with a crew compartment taking the place of the current cargo section.

Mr Zak commented: "I think the main roadmap is the agreement between the European and Russian space agencies. That is their Plan A. Their Plan B is the initiative made by EADS Astrium in Bremen."
But if the agencies want a manned craft capable of reaching the Moon, they will need to develop new, more powerful rockets than those on the drawing board today.
"This is an open question, there are no decisions on how to proceed," said Mr Zak.
The CSTS is also sometimes referred to as the Advanced Crew Transportation System (ACTS). Esa and Roscosmos started talks on the project after some Esa member states rejected further involvement in the development of another manned spacecraft called Kliper.
The proposals will go before a crucial meeting of space ministers from European member states in November this year.

We may all be space aliens: study
PARIS (AFP) - Genetic material from outer space found in a meteorite in Australia may well have played a key role in the origin of life on Earth, according to a study to be published Sunday.
European and US scientists have proved for the first time that two bits of genetic coding, called nucleobases, contained in the meteor fragment, are truly extraterrestrial.
Previous studies had suggested that the space rocks, which hit Earth some 40 years ago, might have been contaminated upon impact.
Both of the molecules identified, uracil and xanthine, "are present in our DNA and RNA," said lead author Zita Martins, a researcher at Imperial College London...

Dark energy 'imaged' in best detail yet

Some had hoped it might be just an illusion. But it looks like dark energy is real and here to stay, as astronomers "image" the mysterious entity in action.
In 1998, astronomers found that distant supernovae were dimmer, and thus farther away, than expected. This suggested that the expansion of the universe is accelerating – and "dark energy" was named as the culprit.
Since then, astronomers have struggled to explain what dark energy actually is – leading some to speculate that it may not exist at all. Some have claimed that uneven distributions of matter within the universe could distort our measurements of the distance to supernovae, fooling us into thinking that they are farther away than they are.
To find an independent check on the existence of dark energy, István Szapudi at the University of Hawaii in Honolulu, US, and colleagues turned to the cosmic microwave background (CMB) – relic radiation from the big bang. Detailed maps of the CMB show hot and cold spots that reflect variations in the density of the early universe.
When dark energy was proposed, astronomers realised that it should create additional temperature bumps on the map.
This extra dark energy effect is generated because the temperature of a photon zipping across the universe can be changed depending on whether it has passed through a region of dense matter or a sparser region.
Shallow well
A photon gains energy when it enters a dense region with enhanced gravity – such as a galaxy cluster – as though it is falling into a well. When it leaves the cluster and climbs back out of the gravitational well, it loses energy.
In a universe without dark energy, the energy gained and lost during the crossing would be equal and would cancel out. But in the presence of dark energy, the universe expands quickly enough to stretch the gravitational well while the photon is still inside. This makes the well shallower and easier for the photon to climb out.
That means that a photon travelling through a cluster gains more energy than it loses, giving it a little energy kick so that it creates a hotter spot than would be expected on images of the CMB. Similarly, a photon that has passed through a void would leave a cold spot.
It's tough to detect this effect because dark energy gives only a slight nudge to the temperature, which is easily swamped by the normal temperature variations seen in the CMB, says Szapudi.
Extreme density
To get around this, his team looked at regions of extremely high and extremely low density, where you would expect to see the biggest effect.
Using data from the Sloan Digital Sky Survey, they chose over 3000 superclusters of galaxies and 500 "supervoids" of relatively empty space, and they found that the regions did indeed tally with enhanced hot and cold spots in the CMB.
Other teams have reported signs of this effect in the past, but those have been open to alternative explanations, says Szapudi. By contrast, his calculations suggest that there is less than a 1 in 200,000 chance that the match up his team saw is down to anything other than dark energy.
"We have shown the imprint on the CMB of dark energy at work," says Szapudi. "In this sense, we have imaged dark energy."
The finding should rule out any notion that dark energy is an illusion, he says. "We've really attacked the dark energy question in a different way from supernovae measurements. It's difficult to argue that an illusion could be responsible for this effect."
Warped space
Thomas Buchert at the University of Lyon in France, one of the physicists who suggested that dark energy may be an illusion, is impressed by the thoroughness of Szapudi's work. "People have discussed this effect, but this is the first really clear-cut signal," he says.
However, Buchert is not ready to abandon alternatives to dark energy just yet. He points out that a similar effect might be produced if space-time is significantly warped around the voids and clusters - something that isn't usually considered in standard calculations.
He also notes that Szapudi's team observed a temperature effect that was stronger than expected from dark energy. "This could be a hint that there may be something else happening here that's worth investigating," he says.
