16/11/2014 - The European Space Agency (ESA)on Sunday unveiled images of the probe Philae after it bounced while making its historic landing on a comet last Wednesday. The discovery came thanks to painstaking follow-up analysis of a series of pictures ESA had released on Friday, the agency said. The photos appeared to show only a trail of dust kicked up by Philae when it touched down and rebounded after a pair of harpoons, designed to anchor it to the comet's surface, failed to work. But closer scrutiny ... (source: - more...)

15/11/2014 - Europe's science probe Philae sent home a treasure trove of data from a comet heading towards the Sun before falling silent as its power ran out, mission control said Saturday. Crowning a historic feat, the robot lab streamed data from its experiments back to its mother ship Rosetta in the final hours before its battery ran down. This included the outcome of an eagerly-waited chemistry test of a sample drilled from the comet's icy and dusty surface, scientists said. "Rosetta's lander has com ... (source: - more...)
