Rosetta found 120 clusters of water ice on the surface of the comet Churyumov-Gerasimenko

Scientists are using high-resolution cameras apparatus Rosetta нашли on the comet Churyumov-Gerasimenko, more than a hundred "patches" of water ice.

When approaching the comet to the sun ice is converted into steam with dust particles, which is then deposited on the surface. This gives the comet dark color. Founded bright spots - water ice.

One of the most important events in in space exploration in 2014 was the mission Rosetta, which included the landing of the probe Philae on the comet Churyumov-Gerasimenko. For the first time in the history of the research unit has reached the surface of the comet. The process did not go as planned, due to a malfunction of harpoons probe bounced off point prikomechivaniya for several kilometers and was lost scientists. The device with Rosetta in August 2014 is located about one hundred kilometers from the comet, sometimes flying up to a distance of ten kilometers to take pictures.

High definition camera OSIRIS, installed on the spacecraft Rosetta, allowed scientists to identify on the surface of the comet's icy hundred and twenty "patches" of a few meters.

In May, the European Space Agency published a all photos , received Philae and Rosetta.

June 13, 2015 Philae probe after 7 months of sleep without the possibility of recharge from the sun woke up and continued to transmit data to Earth. During hibernation Philae continued to collect data - you only transfer them to Earth. Several sessions have already been conducted .

Earlier it was planned that the probe will complete all the tasks before December, but the European Space Agency has decided to extend the his work until the end of 2016.

. ESA_Rosetta , excited to hear we'll be working together for longer than we thought! #lifeonacomet would not be the same without you! - Philae Lander (@ Philae2014) June 24, 2015 blockquote> In the first 60 hours after waking prikomechivaniya Philae had take samples of water vapor on a comet. Studies have shown that the water on the comet three times more deuterium (heavy hydrogen) than water in the earth. Probe to collect more data to scientists appeared rigid base to confirm or refute the theory that water brought to Earth comet.
