Comets TOP STORY
Rosetta's lander Philae will target Site J, an intriguing region on Comet 67P/Churyumov-Gerasimenko that offers unique scientific potential, with hints of activity nearby, and minimum risk to the lander compared to the other candidate sites.

Comet 67P/Churyumov-Gerasimenko is offering mission managers a variety of scientifically useful targets to chose from for the landing site of the Rosetta's small lander Philae. Which location will they select? The announcement is set for Monday, September 15.
Scientists working on images of comet 67P/Churyumov-Gerasimenko have divided the comet's surface into a number of different regions based on their morphology, revealing a unique, multifaceted world.
Using detailed information collected by ESA's Rosetta spacecraft during its first two weeks at Comet 67P/Churyumov-Gerasimenko, five locations have been identified as candidate sites to set down the Philae lander in November - the first time a landing on a comet has ever been attempted.

Rosetta navigation camera image taken on 18 August 2014 at about 84 km from comet 67P/Churyumov-Gerasimenko. The comet nucleus is about 4 km across.
A NASA-led team of scientists has created detailed 3-D maps of the atmospheres surrounding comets, identifying several gases and mapping their spread at the highest resolution ever achieved.
Comet Siding Spring is about to fly historically close to Mars. The encounter could spark Martian auroras, a meteor shower, and other unpredictable effects. Whatever happens, NASA's fleet of Mars satellites will have a ringside seat.
Highlights from ESA's mission control centre during Rosetta's arrival at comet 67P/C-G on 6 August 2014. Includes live updates from the Rosetta flight control team, confirmation of orbit entry and presentation of latest images and science results. Also includes background videos.
The Rosetta Mission Asks: What is a Comet? Scientists attempt to answer these questions and more as the Rosetta Mission's Orbiter arrives and escorts comet 67/p Churyumov Gerasimenko into our inner solar system.
Comet 67P/Churyumov-Gerasimenko by Rosetta's OSIRIS narrow-angle camera on 3 August from a distance of 285 km. The image resolution is 5.3 metres/pixel.
On October 19, 2014, at 18:32 UTC, Comet Siding Spring (2013A1) will pass Mars at roughly 150,000 kilometers, about 1/3 the distance between Earth and the Moon, in a direction putting it on a track for its dust to pass over the Martian North Pole, possibly endangering, over a thirty minute window, the collection of orbital spacecraft currently on station in that region.
A distinct coma surrounds comet 67P/Churyumov-Gerasimenko as seen from Rosetta.
This week's images of comet 67P/Churyumov-Gerasimenko reveal an extraordinarily irregular shape. We had hints of that in last week's images and in the unscheduled previews that were seen a few days ago, and in that short time it has become clear that this is no ordinary comet.
This short animation explains the relative sizes of the Rosetta spacecraft and comet 67P/Churyumov--Gerasimenko.
ESA's Rosetta spacecraft has found that comet 67P/Churyumov-Gerasimenko is releasing the equivalent of two small glasses of water into space every second, even at a cold 583 million kilometers from the Sun.
An image snapped earlier this month by ESA's Rosetta spacecraft shows its target comet has quietened, demonstrating the unpredictable nature of these enigmatic objects.
Three NASA science instruments aboard the European Space Agency's (ESA) Rosetta spacecraft, which is set to become the first to orbit a comet and land a probe on its nucleus, are beginning observations and sending science data back to Earth.
