Rosetta’s lander Philae has woken up after seven months in hibernation on the surface of Comet 67P/Churyumov-Gerasimenko.
The signals were received at ESA’s European Space Operations Centre in Darmstadt at 22:28 CEST on 13 June. More than 300 data packets have been analysed by the teams at the Lander Control Center at the German Aerospace Center (DLR).

ESA’s Rosetta spacecraft has made the first measurement of molecular nitrogen at a comet, providing clues about the temperature environment in which Comet 67P/Churyumov–Gerasimenko formed.
Rosetta arrived last August, and has since been collecting extensive data on the comet and its environment with its suite of 11 science instruments.
The in situ detection of molecular nitrogen has long been sought … Read the rest of this article
Astronomers tinkering with ice and organics in the lab may have discovered why comets are encased in a hard, outer crust.
Using an icebox-like instrument nicknamed Himalaya, the researchers show that fluffy ice on the surface of a comet would crystalize and harden as the comet heads toward the sun and warms up. As the water-ice crystals form, becoming denser … Read the rest of this article
ESA’s Rosetta probe is preparing to make a close encounter with its comet on 14 February, passing just 6 km from the surface.
Yesterday was Rosetta’s last day at 26 km from Comet 67P/Churyumov–Gerasimenko, marking the end of the current orbiting period and the start of a new phase for the rest of this year.
Today, Rosetta is moving into … Read the rest of this article
Where did our planet get its oceans? Among planetary scientists, this is one of the most important and perplexing questions about the origins of Earth.
One popular theory holds that water was brought to Earth by the ancient impacts of comets and asteroids. However, new data from the European Space Agency’s Rosetta spacecraft indicate that terrestrial water did not come … Read the rest of this article
After achieving touchdown on a comet for the first time in history, scientists and engineers are busy analysing this new world and the nature of the landing.
Touchdown was confirmed at ESA’s Space Operations Centre in Darmstadt, Germany at 16:03 GMT/17:03 CET on 12 November.
Since then, scientists, flight dynamics specialists and engineers from ESA, the Lander Control Centre in … Read the rest of this article
There’s an #ESAHangout on results from the comet landing with the Rosetta and Philae teams, today at 13:00 GMT / 14:00 CET.… Read the rest of this article
The Rosetta spacecraft’s Philae lander is safely on the surface of Comet 67P/Churyumov-Gerasimenko, as these first two CIVA images confirm. One of the lander’s three feet can be seen in the foreground. The image is a two-image mosaic. The full panoramic from CIVA will be delivered in this afternoon’s press briefing at 13:00 GMT/14:00 CET.
The first panoramic ‘postcard’ from … Read the rest of this article
After a ten-year journey, Rosetta and Philae had finally reached their destination, Comet 67P/Churyumov–Gerasimenko. Rosetta spent many weeks studying the comet, sending lots of information back to Earth. But where was Philae going to land? Eventually the scientists on Earth found the best place on the comet for Philae to land. Soon it was time to make the final preparations … Read the rest of this article
