Lander manager says Philae is doing well but battery life is low

On the afternoon of 21 March, Comet 252P/LINEAR brushed by Earth just 14 lunar distances away. The comet’s separation from Earth now exceeds 20 million miles, but it’s still a suitable target for binoculars and small telescopes — if you know exactly where to look. Here’s our UK observing guide for 252P/LINEAR in the constellation Ophiuchus between midnight and moonrise over the coming week.

ESA flight director Andrea Accomazzo, says the Philae lander is ready to separate from the Rosetta mothership and touchdown on comet 67P/Churyumov–Gerasimenko.

Views from Europe’s Rosetta comet orbiter show mysterious markings appearing on the nucleus of Comet 67P in recent months, with new surface features forming within a matter of weeks, and scientists are digging into the complex causes of the cometary erosion.
