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

The origin of of Comet 67P/Churyumov-Gerasimenko’s double-lobed form has been a key question since Rosetta first revealed its surprising shape in July 2014. By studying the layers of material seen all over the nucleus, scientists have shown that the shape arose from a low-speed collision between two fully fledged, separately formed comets.

With the transit of Mercury just two days away, interest in this comparatively rare event is growing fast. Given the favourable timing of this 7½-hour phenomenon for the UK, many will be able to view it at lunchtime or after work. If you don’t have suitably equipped telescope, join one of the many transit-viewing activities hosted by astronomical organisations nationwide.

DARMSTADT, Germany — Comet scientists planned to send up new orders to Europe’s Philae lander Thursday to kick off a second day of research after the probe endured a jumpy touchdown on comet 67P/Churyumov-Gerasimenko. Time is of the essence because the oven-sized landing craft is facing a power crunch. The lander bounced across the comet’s tortured landscape before coming to rest near a cliff that blocks sunlight from reaching Philae’s solar panels, meaning the craft’s power generation system may be unable to recharge its batteries. Officials said Thursday the Philae might be on its side, with two of its landing legs contacting the comet’s surface and another off the ground. The first images from Philae’s CIVA camera system — made up of seven micro-cameras in a ring around the lander — appeared to show fragments of rock illuminated by the sun on one side of the probe and the sky on the other side. Philae’s landing legs also appear in the images. “We saw both something that man built — the lander — you see the foot there, and something that nature built 4.6 billion years ago, which is a comet essentially preserved as it was at that time, containing all
