NASA Coverage Set for March 1 SpaceX Mission to Space Station

The second SpaceX mission to the International Space Station under NASA's Commercial Resupply Services contract is scheduled to launch Friday, March 1, from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida. NASA Television coverage begins at 8:30 a.m. EST.

NASA Chief Tours Advanced Manufacturing Facility, Highlights Space Program's Contributions to Industry Sector

NASA Administrator Charles Bolden toured Friday a cutting-edge facility at the agency's Marshall Space Flight Center where high-tech manufacturing is creating parts for a next-generation rocket that will launch astronauts to the most distant destinations ever.

NASA Selects Launch Services for ICESat-2 Mission

NASA's Launch Services Program at the agency's Kennedy Space Center in Florida has selected United Launch Services, LLC of Englewood, Colo., to provide Delta II launch services for the Ice, Cloud and Land Elevation Satellite (ICESat)-2 mission, currently scheduled for July 2016.

Deciphering the mysterious math of the solar wind

(Phys.org)—Many areas of scientific research—Earth's weather, ocean currents, the outpouring of magnetic energy from the sun—require mapping out the large scale features of a complex system and its intricate details simultaneously.

Particle physics research sheds new light on possible 'fifth force of nature'

In a breakthrough for the field of particle physics, researchers have established new limits on what scientists call "long-range spin-spin interactions" between atomic particles. These interactions have been proposed by theoretical physicists but have not yet been seen. Their observation would constitute the discovery of a "fifth force of nature" (in addition to the four known fundamental forces: gravity, weak, strong and electromagnetic) and would suggest the existence of new particles, beyond those presently described by the Standard Model of particle physics.

International collaboration seeks to develop noninvasive quantum electron microscope

Moving closer to creating a microscope that can peer through atoms and molecules without disturbing them, leading physics researchers have joined together with support from the Gordon and Betty Moore Foundation to launch an international collaboration to lay the groundwork for the development of a novel quantum electron microscope.

New way to probe Earth's deep interior proposed

Researchers propose a new technique that might one day reveal in higher detail than ever before the composition and characteristics of the deep Earth. There's just one catch: it relies on a fifth force of nature that has not yet been detected, but which some particle physicists think might exist. If it does, this new force would connect matter at Earth's surface with matter hundreds to thousands of kilometers below, deep in Earth's mantle.

Researchers 'nanoweld' by applying light to aligned nanorods in solid materials

Researchers have developed a way to melt or "weld" specific portions of polymers by embedding aligned nanoparticles within the materials. Their technique, which melts fibers along a chosen direction within a material, may lead to stronger, more resilient nanofibers and materials.

Journey to the limits of space-time: Black hole simulations on supercomputers present new view of jets and accretion disks

Black holes shape the growth and death of the stars around them through their powerful gravitational pull and explosive ejections of energy. In a recent article, researchers predicted the formation of accretion disks and relativistic jets that warp and bend more than previously thought, shaped by the extreme gravity of the black hole and by powerful magnetic forces generated by its spin.

Time reversal findings may open doors to the future

(Phys.org)—Imagine a cell phone charger that recharges your phone remotely without even knowing where it is; a device that targets and destroys tumors, wherever they are in the body; or a security field that can disable electronics, even a listening device hiding in a prosthetic toe, without knowing where it is.
