ESA’s spaceplane back on dry land27 March 2015 ESA’s recovered IXV spaceplane arrived at the Port of Livorno in Italy yesterday and is set to be taken to Turin for final analysis.
Scuttling satellites to save space26 March 2015
Scuttling satellites to save space26 March 2015 It takes a lot of ingenuity – not to mention a massive quantity of sheer force – to get satellites into orbit. Now space engineers are applying comparable ingenuity to the challenge of getting their missions out of there, too.
Black hole winds pull the plug on star formation25 March 2015
Black hole winds pull the plug on star formation25 March 2015 Astronomers using ESA’s Herschel space observatory have found that the winds blowing from a huge black hole are sweeping away its host galaxy’s reservoir of raw star-building material.
Galileo satellites enclosed for Friday’s launch25 March 2015
Galileo satellites enclosed for Friday’s launch25 March 2015 Thousands of engineers have worked on the seventh and eighth navigation satellites of Europe’s Galileo constellation in recent years, but last Friday marked the very last time the spacecraft were glimpsed by human eyes.
Cluster satellite catches up 25 March 2015
Cluster satellite catches up 25 March 2015 One of the four Cluster satellites has shifted its orbit to ensure a safe reentry when the time comes, as well as providing a rare opportunity to study how a satellite’s exhaust plume interacts with the solar wind.
Slight surface movements on the radar23 March 2015
Slight surface movements on the radar23 March 2015 Scientists are making advances in the use of satellite radar data – such as those from the Sentinel-1 mission – to monitor Earth’s changing surface.
Want to snag a satellite? Try a net23 March 2015
Want to snag a satellite? Try a net23 March 2015 One of humanity’s oldest technologies, the humble fishing net, may yet find a new role in space: bringing down dead satellites.
Astronaut plus Proba minisats snap solar eclipse 20 March 2015
Astronaut plus Proba minisats snap solar eclipse 20 March 2015 As today’s partial solar eclipse crossed Europe, it was also visible from space. ESA’s Proba-2 captured a near-total eclipse from orbit, at the same time as its sister minisatellite Proba-V peered down to snap the shadow of the eclipse on Earth.
Protecting Earth from space weather19 March 2015
Protecting Earth from space weather19 March 2015 This week's spectacular glowing auroras in the night sky further south than usual highlighted the effect that 'space weather' can have on Earth. A strong solar flare was detected on the Sun last Sunday, an event generally associated with strong mass...
Galileo meets Galileo as launch draws near18 March 2015
Galileo meets Galileo as launch draws near18 March 2015 The seventh and eighth Galileo satellites, set for launch together in nine days’ time, have been fitted together onto the dispenser that will carry them during their flight to orbit.
Sixth Galileo satellite reaches corrected orbit13 March 2015
Sixth Galileo satellite reaches corrected orbit13 March 2015 The sixth Galileo satellite of Europe’s navigation system has now entered its corrected target orbit, which will allow detailed testing to assess the performance of its navigation payload.
