Predicting daily space weather will help keep your GPS on target
It's well known that severe space weather events – which are quite rare – can have a negative impact on our use of Global Positioning System (GPS) enabled devices. But our research, published in Geophysical Research Letters, shows that another form of space weather – which occurs on ...
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

Engineers achieve first airplane to ground quantum key distribution exchange
Algorithm tested aboard the International Space Station analyzes the rotation of objects in space
Objects in space tend to spin—and spin in a way that's totally different from the way they spin on earth. Understanding how objects are spinning, where their centers of mass are, and how their mass is distributed ...
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 ...
