The United States Air Force's X-37B space plane will launch on its fourth mystery mission next month.
The unmanned X-37B space plane, which looks like a miniature version of NASA's now-retired space shuttle orbiter, is scheduled to blast off atop a United Launch Alliance Atlas V rocket from Florida's Cape Canaveral Air Force Station on May 20.
"We are excited about our fourth X-37B mission," Randy Walden, director of the Air Force Rapid Capabilities Office, said in a statement. "With the demonstrated success of the first three missions, we’re able to shift our focus from initial checkouts of the vehicle to testing of experimental payloads."
The X-37B's payloads and specific activities are classified, so it's unclear exactly what the spacecraft does while zipping around the Earth. But Air Force officials have revealed a few clues about the upcoming mission.
"The Air Force Research Laboratory (AFRL), Space and Missile Systems Center (SMC) and the Air Force Rapid Capabilities Office (AFRCO) are investigating an experimental propulsion system on the X-37B on Mission 4," Capt. Chris Hoyler, an Air Force spokesman, told Space.com via email.
"AFRCO will also host a number of advance materials onboard the X-37B for the National Aeronautics and Space Administration (NASA) to study the durability of various materials in the space environment," Hoyler added.
The Air Force owns two X-37B space planes, both of which were built by Boeing's Phantom Works division. The solar-powered spacecraft are about 29 feet long by 9.5 feet tall (8.8 by 2.9 meters), with a wingspan of 15 feet (4.6 m) and a payload bay the size of a pickup-truck bed. The X-37B launches vertically atop a rocket and lands horizontally on a runway, like the space shuttle did.
One of the two X-37B vehicles flew the program's first and third missions, which were known as OTV-1 and OTV-3, respectively. ("OTV" is short for "Orbital Test Vehicle.") The other spacecraft flew OTV-2. Air Force officials have not revealed which space plane will be going to orbit on the upcoming mission.
OTV-1 launched in April 2010 and landed in December of that year, staying in orbit for 225 days. OTV-2 blasted off in March 2011 and circled Earth for 469 days, coming down in June 2012. OTV-3 launched in December 2012 and stayed aloft for a record-breaking 675 days, finally landing in October 2014.

If Air Force officials know how long OTV-4 is going to last, they're not saying.
"The X-37B is designed for an on-orbit duration of 270 days," Hoyler said. "Longer missions have been demonstrated. As with previous missions, the actual duration will depend on test objectives, on-orbit vehicle performance and conditions at the landing facility."
The secrecy surrounding the X-37B and its payloads has fueled speculation in some quarters that the vehicle could be a space weapon of some sort. But Air Force officials have repeatedly refuted that notion.
"The primary objectives of the X-37B are twofold: reusable spacecraft technologies for America's future in space, and operating experiments which can be returned to, and examined, on Earth," Air Force officials wrote in on online X-37B fact sheet.
"Technologies being tested in the program include advanced guidance, navigation and control; thermal protection systems; avionics; high-temperature structures and seals; conformal reusable insulation, lightweight electromechanical flight systems; and autonomous orbital flight, re-entry and landing."

Moon Express, a Mountain View, California-based company that's aiming to send the first commercial robotic spacecraft to the moon next year, just took another step closer toward that lofty goal.
Earlier this year, it became the first company to successfully test a prototype of a lunar lander at the Kennedy Space Center in Florida. The success of this test—and a series of others that will take place later this year—paves the way for Moon Express to send its lander to the moon in 2016, said company co-founder and chairman Naveen Jain.
Earlier this year, it became the first company to successfully test a prototype of a lunar lander at the Kennedy Space Center in Florida. The success of this test—and a series of others that will take place later this year—paves the way for Moon Express to send its lander to the moon in 2016, said company co-founder and chairman Naveen Jain.
Moon Express conducted its tests with the support of NASA engineers, who are sharing with the company their deep well of lunar know-how. The NASA lunar initiative—known as Catalyst—is designed to spur new commercial U.S. capabilities to reach the moon and tap into its considerable resources.In addition to Moon Express, NASA is also working with Astrobotic Technologies of Pittsburgh, Pennsylvania, and Masten Space Systems of Mojave, California, to develop commercial robotic spacecrafts.
Jain said Moon Express also recently signed an agreement to take over Space Launch Complex 36 at Cape Canaveral. The historic launchpad will be used for Moon Express's lander development and flight-test operations. Before it was decommissioned, the launchpad was home to NASA's Atlas-Centaur rocket program and its Surveyor moon landers.
"Clearly, NASA has an amazing amount of expertise when it comes to getting to the moon, and it wants to pass that knowledge on to a company like ours that has the best chance of being successful," said Jain, a serial entrepreneur who also founded Internet companies Infospace and Intelius. He believes that the moon holds precious metals and rare minerals that can be brought back to help address Earth's energy, health and resource challenges.
Among the moon's vast riches: gold, cobalt, iron, palladium, platinum, tungsten and Helium-3, a gas that can be used in future fusion reactors to provide nuclear power without radioactive waste. "We went to the moon 50 years ago, yet today we have more computing power with our iPhones than the computers that sent men into space," Jain said. "That type of exponential technological growth is allowing things to happen that was never possible before."

"That type of exponential technological growth is allowing things to happen that was never possible before."
An eye on the Google prize

Helping to drive this newfound interest in privately funded space exploration is the Google Lunar X Prize. It's a competition organized by the X Prize Foundation and sponsored by Google that will award $30 million to the first company that lands a commercial spacecraft on the moon, travels 500 meters across its surface and sends high-definition images and video back to Earth—all before the end of 2016.
Moon Express is already at the front of the pack. In January it was awarded a $1 million milestone prize from Google for being the only company in the competition so far to test a prototype of its lander. "Winning the X prize would be a great thing," said Jain. "But building a great company is the ultimate goal with us." When it comes to space exploration, he added, "it's clear that the baton has been passed from the government to the private sector."
Testing in stages
Jain said Moon Express has been putting its lunar lander through a series of tests at the space center. The successful outing earlier this year involved tethering the vehicle—which is the size of a coffee table—to a crane in order to safely test its control systems. "The reason we tethered it to the crane is because the last thing we wanted was the aircraft to go completely haywire and hurt someone," he said.At the end of March, the company will conduct a completely free flight test with no tethering. The lander will take off from the pad, go up and sideways, then land back at the launchpad. "This is to test that the vehicle knows where to go and how to get back to the launchpad safely," Jain explained.
Once all these tests are successfully completed, Jain said the lander—called MX-1—will be ready to travel to the moon. The most likely scenario is that it will be attached to a satellite that will take the lander into a low orbit over the Earth. From there the MX-1 will fire its own rocket, powered by hydrogen peroxide, and launch from that orbit to complete its travel to the moon's surface.
The lander's first mission is a one-way trip, meaning that it's not designed to travel back to the Earth, said Jain. "The purpose is to show that for the first time, a company has developed the technology to land softly on the moon," he said. "Landing on the moon is not the hard part. Landing softly is the hard part."
That's because even though the gravity of the moon is one-sixth that of the Earth's, the lander will still be traveling down to the surface of the moon "like a bullet," Jain explained. Without the right calculations to indicate when its rockets have to fire in order to slow it down, the lander would hit the surface of the moon and break into millions of pieces. "Unlike here on Earth, there's no GPS on the moon to tell us this, so we have to do all these calculations first," he said.
Looking ahead 15 or 20 years, Jain said he envisions a day when the moon is used as a sort of way station enabling easier travel for exploration to other planets. In the meantime, he said the lander's second and third missions could likely involve bringing precious metals, minerals and even moon rocks back to Earth. "Today, people look at diamonds as this rare thing on Earth," Jain said.
He added, "Imagine telling someone you love her by giving her the moon."

Vikings may have been family men who traveled with their wives to new lands, according to a new study of ancient Viking DNA.
Maternal DNA from ancient Norsemen closely matches that of modern-day people in the North Atlantic isles, particularly from the Orkney and Shetland Islands.
The findings suggest that both Viking men and women sailed on the ships to colonize new lands. The new study also challenges the popular conception of Vikings as glorified hoodlums with impressive seafaring skills.
"It overthrows this 19th century idea that the Vikings were just raiders and pillagers," said study co-author Erika Hagelberg, an evolutionary biologist at the University of Oslo in Norway. "They established settlements and grew crops, and trade was very, very important."
Vikings hold a special place in folklore as manly warriors who terrorized the coasts of France, England and Germany for three centuries. But the Vikings were much more than pirates and pillagers. They established far-flung trade routes, reached the shores of present-day America, settled in new lands and even founded the modern city of Dublin, which was called Dyfflin by the Vikings.
Some earlier genetic studies have suggested that Viking males traveled alone and then brought local women along when they settled in a new location. For instance, a 2001 study published in the American Journal of Human Genetics suggested that Norse men brought Gaelic women over when they colonized Iceland.
Modern roots
To learn more about Norse colonization patterns, Hagelberg and her colleagues extracted teeth and shaved off small wedges of long bones from 45 Norse skeletons that were dated to between A.D. 796 and A.D. 1066. The skeletons were first unearthed in various locations around Norway and are now housed in the Schreiner Collection at the University of Oslo.The team looked at DNA carried in the mitochondria, the energy powerhouses of the cell. Because mitochondria are housed in the cytoplasm of a woman's egg, they are passed on from a woman to her children and can therefore reveal maternal lineage. The team compared that material with mitochondrial DNA from 5,191 people from across Europe, as well as with previously analyzed samples from 68 ancient Icelanders.
The ancient Norse and Icelandic genetic material closely matched the maternal DNA in modern North Atlantic people, such as Swedes, Scots and the English. But the ancient Norse seemed most closely related to people from Orkney and Shetland Islands, Scottish isles that are quite close to Scandinavia.
Mixed group
"It looks like women were a more significant part of the colonization process compared to what was believed earlier," said Jan Bill, an archaeologist and the curator of the Viking burial ship collection at the Museum of Cultural History, a part of the University of Oslo.That lines up with historical documents, which suggest that Norse men, women and children — but also Scottish, British and Irish families — colonized far-flung islands such as Iceland, Bill told Live Science. Bill was not involved with the new study.
"This picture that we have of Viking raiding — a band of long ships plundering — there obviously would not be families on that kind of ship," Bill said. "But when these raiding activities started to become a more permanent thing, then at some point you may actually see families are traveling along and staying in the camps."
As a follow-up, the team would like to compare ancient Norse DNA to ancient DNA from Britain, Scotland and the North Atlantic Isles, to get a better look at exactly how all these people are related, Hagelberg said.
The findings were published today (Dec. 7) in the journal Philosophical Transactions of the Royal Society B.
There is nothing better than a bit of mythbusting (which accounts for the popularity of the television program of the same name), so here we are again, presenting you with a new list of terribly common misconceptions and myths – this time about science.
10
Evolutionary Improvements
The Myth: Evolution causes something to go from “lower” to “higher”
While it is a fact that natural selection weeds out unhealthy genes from the gene pool, there are many cases where an imperfect organism has survived. Some examples of this are fungi, sharks, crayfish, and mosses – these have all remained essentially the same over a great period of time. These organisms are all sufficiently adapted to their environment to survive without improvement.
Other taxa have changed a lot, but not necessarily for the better. Some creatures have had their environments changed and their adaptations may not be as well suited to their new situation. Fitness is linked to their environment, not to progress.
9
Humans Pop In Space
The Myth: When exposed to the vacuum of space, the human body pops
This myth is the result of science fiction movies which use it to add excitement or drama to the plot. In fact, a human can survive for 15 – 30 seconds in outer space as long as they breathe out before the exposure (this prevents the lungs from bursting and sending air into the bloodstream). After 15 or so seconds, the lack of oxygen causes unconsciousness which eventually leads to death by asphyxiation.
8
Brightest Star
The Myth: Polaris is the brightest star in the northern hemisphere night sky
Sirius is actually brighter with a magnitude of ?1.47 compared to Polaris’ 1.97 (the lower the number the brighter the star). The importance of Polaris is that its position in the sky marks North – and for that reason it is also called the “North Star”. Polaris is the brightest star in the constellation Ursa Minor and, interestingly, is only the current North Star as pole stars change over time because stars exhibit a slow continuous drift with respect to the Earth’s axis.
7
Five Second Rule
The Myth: Food that drops on the floor is safe to eat if you pick it up within five seconds
This is utter bunkum which should be obvious to most readers. If there are germs on the floor and the food lands on them, they will immediately stick to the food. Having said that, eating germs and dirt is not always a bad thing as it helps us to develop a robust immune system. I prefer to have a “how-tasty-is-it” rule: if it is something really tasty, it can sit there for ten minutes for all I care – I will still eat it.
6
Dark side of the Moon
The Myth: There is a dark side of the moon
Actually – every part of the moon is illuminated at sometime by the sun. This misconception has come about because there is a side of the moon which is never visible to the earth. This is due to tidal locking; this is due to the fact that Earth’s gravitational pull on the moon is so immense that it can only show one face to us. Wikipedia puts it rather smartly thus: “Tidal locking occurs when the gravitational gradient makes one side of an astronomical body always face another; for example, one side of the Earth’s Moon always faces the Earth. A tidally locked body takes just as long to rotate around its own axis as it does to revolve around its partner. This synchronous rotation causes one hemisphere constantly to face the partner body.”
5
Brain Cells
The Myth: Brain cells can’t regenerate – if you kill a brain cell, it is never replaced
The reason for this myth being so common is that it was believed and taught by the science community for a very long time. But in 1998, scientists at the Sweden and the Salk Institute in La Jolla, California discovered that brain cells in mature humans can regenerate. It had previously been long believed that complex brains would be severely disrupted by new cell growth, but the study found that the memory and learning center of the brain can create new cells – giving hope for an eventual cure for illnesses like Alzheimer’s.
4
Pennies from Heaven
The Myth: A penny dropped from a very high building can kill a pedestrian below
This myth is so common it has even become a bit of a cliche in movies. The idea is that if you drop a penny from the top of a tall building (such as the Empire State Building) – it will pick up enough speed to kill a person if it lands on them on the ground. But the fact is, the aerodynamics of a penny are not sufficient to make it dangerous. What would happen in reality is that the person who gets hit would feel a sting – but they would certainly survive the impact.
3
Friction Heat
The Myth: Meteors are heated by friction when entering the atmosphere
When a meteoroid enters the atmosphere of the earth (becoming a meteor), it is actually the speed compressing the air in front of the object that causes it to heat up. It is the pressure on the air that generates a heat intense enough to make the rock so hot that is glows brilliantly for our viewing pleasure (if we are lucky enough to be looking in the sky at the right time). We should also dispel the myth about meteors being hot when they hit the earth – becoming meteorites. Meteorites are almost always cold when they hit – and in fact they are often found covered in frost. This is because they are so cold from their journey through space that the entry heat is not sufficient to do more than burn off the outer layers.
2
Lightning
The Myth: Lightning never strikes the same place twice
Next time you see lightning strike and you consider running to the spot to protect yourself from the next bolt, remember this item! Lightning does strike the same place twice – in fact it is very common. Lightning obviously favors certain areas such as high trees or buildings. In a large field, the tallest object is likely to be struck multiple times until the lightning moves sufficiently far away to find a new target. The Empire State Building gets struck around 25 times a year.
1
Gravity in Space
The Myth: There is no gravity in space
In fact, there is gravity in space – a lot of it. The reason that astronauts appear to be weightless because they are orbiting the earth. They are falling towards the earth but moving sufficiently sideways to miss it. So they are basically always falling but never landing. Gravity exists in virtually all areas of space. When a shuttle reaches orbit height (around 250 miles above the earth), gravity is reduced by only 10%.

With Interstellar blowing minds in theaters, interest in space exploration is heightened with the public. Not that we ever stopped thinking about it, we just put it on the back burner and forgot about it for far too long. This short film from Erik Wernquist is hoping we start to remember it.
Utilizing Carl Sagan’s Pale Blue Dot for narration, Wernquist creates a stunning trip through the galaxy to paint a picture of a future where we venture out. It’s a hell of a ride with no shortage of beauty. From the video:
Wanderers is a vision of humanity’s expansion into the Solar System, based on scientific ideas and concepts of what our future in space might look like, if it ever happens. The locations depicted in the film are digital recreations of actual places in the Solar System, built from real photos and map data where available.
Without any apparent story, other than what you may fill in by yourself, the idea with the film is primarily to show a glimpse of the fantastic and beautiful nature that surrounds us on our neighboring worlds – and above all, how it might appear to us if we were there.Sagan’s word really help to push it past just a beautiful visual piece. It’s a good introduction, along with the original Cosmos, into how he could describe these events in a way that established some wonder. From Sploid:
Your own life, or your band’s, or even your species’ might be owed to a restless few—drawn, by a craving they can hardly articulate or understand, to undiscovered lands and new worlds.
Rosetta Mission: European Space Agency Scientists Worry Philae Probe Is Running Out of Battery Power
 |
| Philae lander harpooned into comet |
Excerpt from online.wsj.com
By Gautam Naik & Robert Wall
Situation Could Mean Early End for Important Experiments on Comet
The researchers will only know whether the primary batteries have drained or not late Friday, when they try to re-establish a radio link to the probe via Rosetta, a spacecraft in orbit around the comet. The probe and Rosetta can typically communicate twice a day because at other times the orbiter is below the horizon and can’t establish a direct signal.
Scientists are hoping to get contact around 10 p.m. German time, said Stephan Ulamec, who oversees operation for the lander. But if Philae fails to send a signal, he added, it would mean the battery had run out of juice.
The plan was for Philae to do scientific experiments for an initial 2 ½ days on primary battery power and then switch to solar panels that would keep it ticking for another three months. But because of an awkward landing near the face of cliff, the probe’s solar panels are being exposed to far less sunlight than was expected.
Despite the hitch, Philae has already done a significant amount of science on its new home. Its 10 instruments have so far garnered between 80%-90% of the data they were designed to collect, according to Dr. Ulamec.
It has beamed back detailed photographs of the comet’s rough terrain, analyzed the gases, and taken the comet’s temperature. It is now using radio waves to probe the comet’s nucleus and searching for organic molecules on the hostile surface.
Anticipating a possible loss of battery power, ESA scientists activated a drill during their last contact with the lander. The machine is designed to dig up the comet’s subsurface material and rotate it through an onboard oven to investigate its components.
There may still be a way to extend Philae’s working life. During every 12-hour rotation of the comet, one of the lander’s solar panels is now exposed to an hour and 20 minutes of sunlight, while two other panels get the sun for less than 30 minutes each.
Provided the signal to Philae can be re-established, scientists said they could rotate the lander slightly so that one of its larger solar panels can catch more sunlight. Another option is to eject the probe from its current location in the hope it lands in a spot where there is more sun.

Rosetta mission controllers must decide whether to risk making lander hop from shadow of cliff blocking sunlight to its solar panels.
The robotic lander that touched down on a comet on Wednesday came to rest on its side in the shadow of a cliff, according to the first data beamed home from the probe.
Pictures from cameras on board the European Space Agency’s Philae lander show the machine with one foot in the sky and lodged against a high cliff face that is blocking sunlight to its solar panels.
The precarious resting place means mission controllers are faced with some tough decisions over whether to try and nudge the spacecraft into a sunnier spot. If successful, that would allow Philae to fully recharge its batteries and do more science on the comet, but any sudden move could risk toppling the lander over, or worse, knock it off the comet completely.
The washing machine-sized lander was released by its Rosetta mother ship at 0835am GMT on Wednesday morning and touched down at a perfect spot on the comet’s surface. But when anchoring harpoons failed to fire, the probe bounced back off into space. So weak is the gravitational pull of the comet that Philae soared 1km into the sky and did not come down again until two hours later. “We made quite a leap,” said Stephan Ulamec, the Philae lander manager.
In the time it took the probe to land for the second time, the comet had rotated, bringing more treacherous terrain underneath. The spacecraft bounced a second time and finally came to a standstill on its side at what may be the rim of an enormous crater.
“We bounced twice and stopped in a place we’ve not entirely located,” said Jean-Pierre Bibring, Philae’s lead scientist. Teams of scientists are now trying to work out where the probe is. What mission controllers do know is that they are not where they hoped to be. “We are exactly below a cliff, so we are in a shadow permanently,” Bibring added.
With most of Philae in the dark, the lander will receive only a fraction of the solar energy that Esa had hoped for. The spacecraft needs six or seven hours of sunlight a day but is expected to receive just one and a half. Though it can operate for 60 hours on primary batteries, the probe must then switch to its main batteries which need to be recharged through its solar arrays. If Philae’s batteries run out it will go into a hibernation mode until they have more power.
The spacecraft was designed with landing gear that could hop the probe around, but from its awkward position on its side the option is considered too risky.
Though caught in a tight spot, the Philae lander’s systems appear to be working well. The Rosetta spacecraft picked up the lander’s signal on Thursday morning and received the first images and more instrument data from the surface of the comet.
One of Philae’s major scientific goals is to analyse the comet for organic molecules. To do that, the lander must get samples from the comet into several different instruments, named Ptolemy, Cosac and Civa. There are two ways to do this: sniffing and drilling. Sniffing involves opening the instruments to allow molecules from the surface to drift inside. The instruments are already doing this and returning data.
Drilling is much riskier because it could make the lander topple over... Pushing down into the surface will push the lander off again. “We don’t want to start drilling and end the mission,” said Bibring.
But the team has decided to operate another moving instrument, named Mupus, on Thursday evening. This could cause Philae to shift, but calculations show that it would be in a direction that could improve the amount of sunlight falling on the probe. A change in angle of only a few degrees could help. A new panoramic image will be taken after the Mupus deployment to see if there has been any movement.
Meanwhile, the Rosetta orbiter team will continue to try to pinpoint Philae’s position.

By Devin ColdeweyNo one seems to know much about the Air Force's X-37B secret space plane except that it appears to be working exactly as designed. The unmanned Boeing-built craft, which resembles a miniature space shuttle, returned to Earth on Friday after nearly two years — 674 days, to be exact — in space. It's the X-37B program's third mission to space and by far the longest.
The plane landed at 9:24 a.m. local time on Oct. 17 at Vandenberg Air Force Base in California, the Air Force's 30th Space Wing announced.
"The 30th Space Wing and our mission partners, Air Force Rapid Capabilities Office, Boeing, and our base support contractors, have put countless hours of hard work into preparing for this landing and today we were able to see the culmination of that dedication," Colonel Keith Balts, 30th Space Wing commander, said in a release. "I'm extremely proud of our team for coming together to execute this third safe and successful landing. Everyone from our on console space operators to our airfield managers and civil engineers take pride in this unique mission and exemplify excellence during its execution."
But just what did the X-37B do up there? Officially, the Air Force isn't telling.
What is known is that the X-37B has no human pilot, or at least not one in its windowless cockpit. It's operated remotely and lands on its own.
The plane's size means there isn't room on board for much except avionics equipment, fuel for the thrusters, and a mysterious cavity about the size of a truck bed that could contain all manner of sensors, experiments, hardware — perhaps some bacterial colonies, or a bomb. No one can be sure what's inside.
