ESA to host workshop aimed at cleaning up low-Earth orbit

Key orbits frequented by GPS and communications satellites are becoming more and more hazardous, as man-made debris presents an increasingly palpable danger to the valuable assets orbiting at heights of around 2,000 km (1,243 miles) above the Earth. That' s why the European Space Agency (ESA) is hosting an international workshop geared towards cleaning up low-Earth orbit, with a focus on how to make the space industry more sustainable.

Cluster satellites come within cosmic hairsbreadth

Space maneuvers have often been described as an orbital ballet, but the European Space Agency's (ESA) Cluster II satellites are currently in a ballet where the dancers are moving blindfolded at hypersonic speeds as they pass within a cosmic hairsbreadth of one another. That's because two of the Cluster satellites are flying within "touching distance" of one another as scientists try to learn more about the effects of solar wind on the Earth's magnetic field.Read More

Dish launches Sling TV: Live TV over the internet for cord cutters

In the United States, more and more television programming has become available for streaming online thanks to names like Hulu, Amazon and many of the TV networks themselves, but being able to watch live television and events like sports and live news online has remained elusive for cord cutters. Dish took a big move towards changing that here at CES 2015, announcing the launch of Sling TV to deliver live channels to connected devices like Amazon Fire TV, Roku, Xbox and others.Read More

Startup helps you build your very own picosatellite on a budget

A Glasgow-based startup is reducing the cost of access to space by offering "satellite kits" that make it easier for space enthusiasts, high schools and universities alike to build a small but functional satellite for as little as US$6,000 and then, thanks to its very small size, to launch for significantly less than the popular CubeSats.Read More

CryoSat records small decrease in Arctic ice volume

The European Space Agency’s CryoSat mission has returned its latest map of Arctic sea ice volumes, recording a slight decrease in thickness over previous measurements. The data flies in the face of the previous downward trend, which was much greater, but is unlikely to indicate a shift in the accepted pattern of degradation. Read More

NASA to deploy four spacecraft to study magnetic reconnection

NASA has released a video depicting the initial deployment of an undertaking designed to study a phenomenon known as magnetic reconnection. The launch of the Magnetospheric Multiscale (MMS) mission will see four identical spacecraft deployed from a single Atlas V rocket, set to lift off from cape Canaveral, Florida, no earlier than March next year.

GPS satellites to aid in hunt for elusive dark matter

Dark matter is hypothesized to account for the large amounts of "missing" invisible matter in the universe where visible objects such as stars, gas, and dust are insufficient to explain the total gravitational effects observed. Despite repeated and verifiable observational evidence supporting this hypothesis, the existence of dark matter remains unproven. However, recent research has suggested that the hunt for this elusive substance may be aided by detecting any changes in the synchronization between the individual atomic clocks on-board satellites in the orbiting GPS network and receivers on the ground as waves of dark matter pass between them and the surface of the Earth.Read More
