Astronomers shed new light on explosive solar activity
(Phys.org) -- The first images of an upward surge of the Sun's gases into quiescent coronal loops have been identified by an international team of scientists. The discovery is one more step towards understanding ...
Scientists prove existence of 'magnetic ropes' that cause solar storms
George Mason University scientists discovered recently that a phenomenon called a giant magnetic rope is the cause of solar storms. Confirming the existence of this formation is a key first step in helping ...
Metamaterials approach makes better satellite antennas
(PhysOrg.com) -- Cheaper, lighter and more energy-efficient broadband devices on communications satellites may be possible using metamaterials to modify horn antennas, according to engineers from Penn State ...
Satellite reaches California for next Sea Launch
A communications satellite built for France-based Eutelsat has arrived in California to be prepared for liftoff from Sea Launch AG's oceangoing rocket pad.
Engineers achieve first airplane to ground quantum key distribution exchange
Biggest solar storm since 2005 pummels Earth
A potent solar flare has unleashed the biggest radiation storm since 2005 and could disrupt some satellite communications in the polar regions, US space weather monitors said Monday.
US company aims to 'harvest' asteroids
A US company said Tuesday it plans to send a fleet of spacecraft into the solar system to mine asteroids for metals and other materials in the hopes of furthering exploration of the final frontier.
How astronauts can explore the Martian moon Phobos
Humans would spend more than a year orbiting and bouncing on the Martian moon Phobos under a mission concept developed by students at the International Space University.
SpaceX launch good for NASA, not private firm (Update)
A private rocket successfully sent a capsule full of cargo zipping toward the International Space Station in a first of its kind delivery for NASA, but couldn't deliver on job No. 2: putting a commercial satellite into the ...
150-foot asteroid will buzz Earth, no need to duck (Update 2)
A 150-foot(45-meter)-wide asteroid will come remarkably close to Earth next week, even closer than high-flying communication and weather satellites. It will be the nearest known flyby for an object of this ...
NASA to demonstrate communications via laser beam
It currently takes 90 minutes to transmit high-resolution images from Mars, but NASA would like to dramatically reduce that time to just minutes. A new optical communications system that NASA plans to demonstrate ...
US military looks for new life for dead satellites
It's like doing robotic surgery in zero gravity: Imagine scavenging defunct communication satellites for their valuable parts and recycling them to build new ones for cheap.
