The Next Human Spacecraft, C/O SpaceX and Elon Musk The Slatest (blog) In a press conference last night, Elon Musk, CEO of the private space company SpaceX, unveiled the new Dragon V2, the company's next-generation crewed space vehicle.
Space Exploration Technologies, led by billionaire Elon Musk, is poised to break into the U.S. military’s $70 billion launch market after winning its first missions from the Pentagon.
The Defense Department on Nov. 27 directed the Air Force to end a launch monopoly held by the government’s two biggest contractors, Lockheed Martin and Boeing. A week later, the service awarded the trial missions to Musk’s firm, known as SpaceX.
The Lockheed-Boeing venture has had a lock on the business for six years. SpaceX, which recently showed it could fly to the international space station, now has the opportunity to prove that its rockets are capable of launching satellites serving Pentagon planners, ground troops and the nation’s spies.
“The one market they have really yet to crack so far is the military launch market,’’ said Jeffrey Foust, a senior analyst at Futron, a technology consulting firm based in Bethesda. “They’re just starting to do that now.”
Researchers at MIT have discovered a new state of matter with a new kind of magnetism. This new state, called a quantum spin liquid (QSL), could lead to significant advances in data storage.
Researchers at MIT have discovered a new state of matter with a new kind of magnetism. This new state, called a quantum spin liquid (QSL), could lead to significant advances in data storage. QSLs also exhibit a quantum phenomenon called long-range entanglement, which could lead to new types of communications systems, and more.
Generally, when we talk about magnetism’s role in the realm of technology, there are just two types: Ferromagnetism and antiferromagnetism. Ferromagnetism has been known about for centuries, and is the underlying force behind your compass’s spinning needle or the permanent bar magnets you played with at school. In ferromagnets, the spin (i.e. charge) of every electron is aligned in the same direction, causing two distinct poles. In antiferromagnets, neighboring electrons point in the opposite direction, causing the object to have zero net magnetism (pictured below). In combination with ferromagnets, antiferromagnets are used to create spin valves: the magnetic sensors used in hard drive heads.
In the case of quantum spin liquids, the material is a solid crystal — but the internal magnetic state is constantly in flux. The magnetic orientations of the electrons (their magnetic moment) fluctuate as they interact with other nearby electrons. “But there is a strong interaction between them, and due to quantum effects, they don’t lock in place,” says Young Lee, senior author of the research. It is these strong interactions that apparently allow for long-range quantum entanglement.
WEDGED between a strip-mall chiropractor and a cluster of optometrists in Rochester, N.Y., the offices of the DePrez Group of Travel Companies hardly seems like the kind of place where someone would begin a journey to the stars.
But Craig Curran, the company’s president, says that’s exactly where he can take you — provided, of course, that you have a spare $200,000 lying around. Mr. Curran, you see, is a so-called “accredited space agent” for Virgin Galactic, an outfit founded by the multitasking mogul Richard Branson that is promising to take hundreds of high rollers some 60 miles up in a futuristic craft known as the SpaceShipTwo. And while the flight lasts only two hours or so, with a mere five minutes spent coasting in weightlessness, the bragging rights will go on forever.

Earlier this week, the space-transport start-up SpaceX had its most successful launch test yet with Grasshopper, the first fully and rapidly reusable rocket. This is the latest step in the company's journey to dramatically reduce the cost of space travel, and follows the first private resupply of the International Space Station with the launch of their Falcon 9 rocket and Dragon spacecraft last fall.
Initially when the start-up's founder, serial entrepreneur Elon Musk, looked at the space industry, he faced a quandary about where to innovate, given the restrictions and mandatory performance criteria for space travel. Musk quickly zeroed in on the one area ripe for innovation: cost reduction. He gathered a team with a wide cross-section of expertise and put them to work at trimming the fat.
Reflecting back upon 2012, I am impressed by the strides Astronauts4Hire has made to firmly establish itself as an important leader in the commercial spaceflight industry. Our primary mission is to build the next generation astronaut workforce by providing skills training, networking, and other professional development opportunities to aspiring commercial astronauts. As a 501(c)(3) educational nonprofit, we rely upon the volunteer efforts of our members, generosity of our sponsors, and collaboration with our partners to meet our goals. With your help, we have achieved a lot in the past year, including:
On Thursday, August 23, NASA Administrator Charles Bolden visited SpaceX's main hangar at Launch Complex 40 in Cape Canaveral, FL to announce that SpaceX has officially entered NASA's Commercial Resupply Services (CRS) program.
