British astronaut gets set to run space marathon

British astronaut Tim Peake says he’ll follow in the footsteps of NASA’s Sunita Williams by running a marathon in orbit on the International Space Station.

Peake is due to ride a Russian Soyuz craft to the station for a six-month stint on Dec. 15, which should give him plenty of zero-G training time for the London Marathon on April 24. While more than 30,000 runners make their way through the course’s 26 miles and 385 yards on Earth, Peake will run the same distance on the station’s treadmill, held down by a harness to keep him on track.

He’s running the race to raise awareness for the Prince’s Trust, a youth charity co-founded by Britain’s Prince Charles.

Scientists set up systems for DNA data storage

Data storage is getting better and better, but the final frontier for the long-term preservation of digital bits may well be DNA molecules – and the University of Washington and Microsoft Research are trying to make it so.

The work on DNA data storage architecture is one of the angles in Friday’s New York Times story on the subject. In a paper prepared for an international conference on software architecture, researchers propose an error-tolerant encoding scheme for reading out the data in a DNA-based storage system.

Such a system would take advantage of DNA’s amazing information storage capability – the kind of capability that’s able to hold all the genetic code for any organism in a single cell. The Times notes that all of the world’s digital information could be stored in about 2.4 gallons (9 liters) of solution, which would fit inside a typical water cooler bottle.

The benefits of such a system not only include being able to put a lot of data in a small space, but also being able to preserve the data for millennia under the right conditions.

Watch Blue Origin’s rocket scientists get happy

“Touchdown” means something different to rocket scientists and to football fans, but the cheering, hugs and high fives are the same – as revealed today in a Blue Origin video.

The video shows how the Nov. 23 landing of Blue Origin’s New Shepard suborbital spacecraft played out, as seen from four perspectives. Two views showed how the autonomous landing went down at the company’s test range in West Texas. The other two views showed the reaction of Blue Origin employees who gathered at the company’s headquarters in Kent, Wash.

Jeff Bezos, the billionaire founder of Blue Origin as well as the better-known Amazon online commerce venture, touted the video in the third tweet he’s ever posted.

Virgin Galactic will use jet as rocket mothership

Virgin Galactic showed off its latest mothership today: a Boeing 747-400 jet that it acquired from its corporate cousins at Virgin Atlantic to serve as the platform for its LauncherOne rocket.

LauncherOne is designed to be launched from a high-flying carrier airplane and send small-scale satellites into orbit. It will use a liquid-fueled engine called Newton, which is still under development. The launch system is expected to be in operation by 2018, and it’s already been tapped by OneWeb to help put a global Internet constellation into orbit.

It was previously thought that LauncherOne would use Virgin Galactic’s WhiteKnightTwo carrier plane. That’s the mothership being used for SpaceShipTwo, Virgin Galactic’s rocket-powered passenger space plane. But Virgin Galactic said the 747 was more suited for LauncherOne’s upgraded payload capacity and flight rate.

LISA Pathfinder blazes trail to test relativity

The LISA Pathfinder probe is heading for a vantage point a million miles from Earth to help look for gravitational waves and add a missing piece to the evidence for general relativity.

The European Space Agency said an Italian-built Vega rocket sent the spacecraft into low Earth orbit from ESA’s spaceport on the South American coast, at Kourou in French Guiana, at 04:04 GMT today (8:04 p.m. PT Wednesday).

Over the next two weeks, LISA Pathfinder will go through a series of maneuvers to set a course for L1, a gravitational balance point between Earth and the sun. The spacecraft is due to reach L1 in mid-February and begin its scientific mission in March.

In this age of e-readers, there are still occasions when it’s nice to have a book printed on actual paper – like holiday giving, for instance. But which book works best as a gift for a science geek?

In honor of the 12 days of Christmas, here are a dozen recently published science books that have been well-received and are well-suited for gift wrapping. And if you still want to save a tree, some of them work just fine as e-books as well.

Coast Guard copter hit by laser flash

The U.S. Coast Guard says it had to cut a helicopter training mission short on Monday night after the airborne crew was targeted by someone with a laser near Port Angeles, Wash.

The laser was directed at the MH-65 Dolphin helicopter at around 6:30 p.m., forcing the crew to abort the flight and return to Air Station Port Angeles. “No injuries were reported, but all crew members are grounded until they are cleared by medical personnel, as laser strikes can cause permanent eye damage,” the Coast Guard said today in a statement.

The Coast Guard said it was working with local law-enforcement officials to investigate the incident.

R2-D2 jet brings ‘Star Wars’ vibe to Seattle

All Nippon Airways’ R2-D2 Dreamliner jet touched down today at Seattle-Tacoma International Airport for the first time, two and a half months after the 787 rolled out of Boeing’s Everett factory.

The airliner – decorated in a blue, black, gray and white scheme modeled after the adorable Star Wars robot – is taking on several Seattle-Tokyo flights this month. The timing is perfect for ANA to capitalize on the hype over “Star Wars: The Force Awakens.” And Seattle fans of the movie series, or just plain cool-looking jets, ate it up.
