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.
America's SpaceX - there's no need to whisper the name - is wooing satellite operators with rides on its Falcon 9, for ticket prices that substantially undercut the Ariane 5.
Efforts have been made to push forward with a next-generation European rocket - an Ariane 6 - that could be made much more cheaply. But the concept, which has been studied for the past 18 months, has left most observers flat.
More importantly, it has underwhelmed the satellite operators as well, which is why a new concept has now been sprung on the world by Airbus Defence and Space, and Safran - the main players in Ariane production.
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.
Rosetta: Icy quarry coming into view
Take your seats because the show is about to begin.
The European Space Agency's Rosetta probe is edging ever closer to the Comet 67P/Churyumov-Gerasimenko for what is expected to be one of the most daring space encounters in history.
Skylon ‘spaceplane economics stack up’
It appears a feasible proposition, economically. That is the conclusion of a study that considered a European launch service based on a Skylon re-usable spaceplane.
The report, commissioned by the European Space Agency (Esa), was led by Reaction Engines Limited (REL) of Oxfordshire with help from a range of other contractors such as London Economics, QinetiQ and Thales Alenia Space (TAS).
MH370 spur to 'better ocean mapping'
Scientists have welcomed the decision to make all ocean depth data (bathymetry) gathered in the search for missing Malaysia Airlines flight MH370 publicly available.
A detailed survey of 60,000 sq km of seabed is to be undertaken to help refine the hunt for the lost jet.
Flight MH370: Malaysia releases raw satellite data
The release document comprises long columns of numbers, including detail on the now famous "handshakes" when Inmarsat's ground network made connections with equipment on board the plane.
The last of these occurred at 00:19:38 UTC. It's a partial handshake, possibly the plane attempting to log back on to the network after a power interruption as the jet ran out of fuel.
Ukraine crisis sends a chill into orbit
A Soyuz capsule returned to Earth on Wednesday with its international cosmonauts.
Russian Mikhail Tyurin, American Rick Mastracchio and Japan's Koichi Wakata had spent 188 days orbiting the planet on the International Space Station.
SpaceX rocket stage in 'soft landing'
SpaceX says its recent experiment to return part of its Falcon-9 rocket back to Earth under control was a success.
The US company has confirmed that the first-stage of the vehicle launched from Cape Canaveral a week ago used its engines to slow its fall, deployed a set of legs and made a "soft landing".
