After travelling nearly 6.4 billion kilometres through the Solar System, ESA’s Rosetta is closing in on its target. But how does a spacecraft actually arrive at a comet? The journey began on 2 March 2004 when Rosetta was launched on an Ariane 5 from Europe’s Spaceport in Kourou, French Guiana. Since then, Rosetta has looped around the Sun five times, picking up speed through three gravity-assist swingbys at Earth and one at Mars, to enter an orbit similar to that of its de...

New research shows that more than four billion years ago the surface of Earth was heavily reprocessed – or melted, mixed, and buried – as a result of giant asteroid impacts. A new terrestrial bombardment model, calibrated using existing lunar and terrestrial data, sheds light on the role asteroid collisions played in the evolution of the uppermost layers of the early Earth during the geologic eon called the "Hadean" (approximately 4 to 4.5 billion years ago). An inte...

Evry -  European space telecommunications operator Eutelsat has chosen Arianespace to launch its 172B satellite. EUTELSAT 172B will be equipped with a multibeam payload covering the Asia-Pacific region, designed specially to support in-flight connectivity services aboard airliners.   The Eutelsat 172B satellite will be launched by an Ariane 5 in 2017 from the Guiana Space Center in Kourou, French Guiana. This will be the 28th satellite lofted into orbit by Arianespace for Eutelsat. ...

NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, a premier black-hole hunter among other talents, has finished up its two-year prime mission, and will be moving onto its next phase, a two-year extension. "It's hard to believe it's been two years since NuSTAR launched," said Fiona Harrison, the mission's principal investigator at the California Institute of Technology in Pasadena. "We achieved all the mission science objectives and made some amazing d...

Observations by NASA's Fermi Gamma-ray Space Telescope of several stellar eruptions, called novae, firmly establish these relatively common outbursts almost always produce gamma rays, the most energetic form of light. "There's a saying that one is a fluke, two is a coincidence, and three is a class, and we're now at four novae and counting with Fermi," said Teddy Cheung, an astrophysicist at the Naval Research Laboratory in Washington, and the lead author of a paper ...
