Sentinel system pictures Napa quake
Europe's new multi-billion-euro Sentinel programme has returned its first earthquake analysis.
The EU satellite system has pictured how the Earth moved when the Magnitude 6.0 tremor hit California's wine-producing Napa region last month.
Scientists will use the figure, called an interferogram, to trace precisely the extent of the fault rupture.
In the past, this type of analysis has been very time-consuming, but the Sentinel project will now automate it.
Interferograms that once took many weeks, even months, to produce should in future come out within days of a big quake.
Rosetta's 10-billion-tonne comet
The comet being followed by Europe's Rosetta spacecraft has a mass of roughly 10 billion tonnes.
The number has been calculated by monitoring the gravitational tug the 4km-wide "ice mountain" exerts on the probe.
DigitalGlobe launches super-sharp WorldView-3 Earth imager
Rosetta heads for space 'rubber duck'
Europe's mission to land on a comet was always going to be difficult, but the pictures released this week of the giant ice ball illustrate just how daunting the task will be.
Comet 67P/Churyumov-Gerasimenko is far more irregular in shape than anyone imagined.
Spaceport Britain: 'No challenge is insurmountable'
It's more than 40 years since Britain abandoned its own launch capability, cancelling the Black Arrow programme just as it successfully lofted the Prospero satellite.
The subsequent withdrawal from the European Ariane programme confirmed Britain's deep aversion to rockets. Until now. The climate is changing. Ministers are putting public funds (albeit a small sum) into an air-breathing rocket-engine technology, and they've declared their desire to see a home spaceport.
Rosetta: 'Spuds in space'
With the Rosetta probe closing in on Comet 67P/Churyumov-Gerasimenko, we're beginning to get a sense of the ice mountain's shape.
The latest picture release from the European Space Agency (Esa) may only cover an area of about 30 pixels, but it's clear that 67P is no sphere. In some views, the object appears quite elongated.
Ariane 6: Customers call the shots
Europe's rocket industry is currently going through something of an epiphany - the realisation that it must adapt, and fast, or simply become irrelevant.
More than half of the big commercial satellites that are working up there - the ones that relay our TV, phone calls, and internet traffic - were lofted by Ariane vehicles. But that dominance is now under threat from new launchers that promise to undercut Europe's best on price.
Rosetta edges towards Comet 67P
Europe's Rosetta spacecraft is edging ever closer to its quarry - the 4km-wide Comet 67P/Churyumov-Gerasimenko.
Thursday's separation is just 43,000km, and the narrowing gap is evident in the probe's latest photo release.
Malaysian jet MH370: Refined analysis drives new search area
As expected, and reported by the BBC last week, the search for MH370 is going to shift hundreds of kilometres to the south of where an Australian defence vessel thought, mistakenly, it had detected signals from the jet’s submerged flight recorders.
The new region is a consequence of further, refined analysis of the brief, automated satellite communications with the plane in its last hours.
