Rosetta hits 'milestone' in comet's run past Sun
Paris (AFP) Aug 14, 2015
The European space probe Rosetta captured a range of scientific data Thursday as it trailed an ancient comet past the Sun which could help scientists better understand the origins of life on Earth. During its run before the Sun the probe collected particles and gas put off by the comet 67P/Churyumov-Gerasimenko as it delivered a solar heat-driven fireworks show of gas jets and shed about a tonne of dust per second. The samples as well as images Rosetta took of the comet as it came within 186 mi ... read more
