Some tricky maneuvers are now under way to steer ESA’s trio of Swarm satellites into their respective orbits so that they can start delivering the best-ever survey of our magnetic field.
When satellites reach the end of their working lives, they may pose a threat to other spacecraft as they continue to orbit in a dormant state for many decades. But now a new way to deorbit ageing satellites in a safe manner is nearing its first test in space.
The belief that the US government will be using drones to spy on its citizens might not have any basis, as its security forces move towards satellite spying instead.
A new study of glaciers worldwide using observations from two NASA satellites has helped resolve differences in estimates of how fast glaciers are disappearing and contributing to sea level rise.
In-flight internet speeds could soon match speeds on mother Earth if a Qualcomm proposal to use satellites is approved by regulators.
Physicists believe they can provide secret keys using quantum cryptography via satellite.
UK engineers have carried out a detailed assessment of the risks from solar superstorms, and say governments need to do more to protect against them.
DARPA has released a video detailing some of the progress it's made with its Phoenix project for repurposing existing satellites.
Russia has restored full communication with the International Space Station after a cable break cut off not just the ISS but civilian satellites too.
Rising levels of carbon dioxide in the atmosphere are leaking out to the edge of space and interfering with satellites, new research shows.
Thrusters no bigger than a penny could soon be moving satellites around, thanks to MIT engineers.
Almost all of Greenland's surface ice cover has melted at some point this summer - twice as much as usual. It's the largest melt ever seen in more than 30 years of satellite observations.
Scottish engineers have come up with a new way of dealing with asteroids that threaten the Earth - firing lasers at them from a swarm of small satellites flying in formation.
A newly discovered asteroid will come so close to Earth next year that it actually passes below many man-made satellites.
The Pentagon's calling for proposals for a fleet of cheap, disposable satellites to give soldiers access to battlefield maps and images.
Europe's new Vega rocket has successfully lifted off from the Kourou spaceport in French Guiana, taking nine satellites into orbit.
The Hackerspace Global Grid is hoping to build its own satellite network in an effort to counter various Internet censorship initiatives such as the controversial Stop Online Piracy Act (SOPA) act.
China's released a white paper setting out its plans to accelerate space activities over the next five years.
It's a bit of a push as claims go: most satelites orbit at a distance of about 200 miles, compared with the 85-mile range of the S3 Krypton Series. Nevertheless, it's a bit more powerful than your average laser pointer.
