Detailed analysis of data collected by #Rosetta show that comets are the ancient leftovers of early Solar System formation, and not younger fragments resulting from subsequent collisions between other, larger bodies.

A few words from ESA Director General Jan Woerner on the exciting events of the past few months. #TimPeake #Brexit   #Europe   
Tweet After ESA astronaut Tim Peake returned home safely from his very successful and eventful mission, I was able to catch up with him in northern Norway en route from Kazakhstan with his NASA crewmate Tim Kopra. Even before setting off on his mission, Tim Peake had become something of a national hero but now he is known across Europe as a European Astronaut of British nationality. He proves day in, day out that ESA does not just talk about Euro...

Today #ExoMars feels the #BigBurn ! ExoMars/TGO will conduct one of the most critical activities during the voyage to #Mars: a very large engine burn in deep space (DSM-1) that starts at 09:30 UTC (11:30 CEST), runs for about 50 mins and that is planned to change the craft’s direction and speed ('delta-v') by 326.497 m/second.

Help to say #GoodbyePhilae - find out how with +DLR, German Aerospace Center 
 
From #CometLanding to #GoodbyePhilae - tomorrow, the 27/07/2016, communication with the Philae comet lander will no longer be possible.
Join us and our partners in saying goodbye to #Philae 
On 27 July 2016, the Electrical Support System (ESS) on Rosetta, which is used to communicate with Philae, will be switched off to save energy before September 30, the day the Rosetta mission will come to an end. We invite you all to help us and our partners say goodbye to Philae.

#Operations image of the week features the #ExoMars mission controllers. Following a lengthy firing of its powerful engine, ESA’s ExoMars Trace Gas Orbiter is on track to arrive at the Red Planet in October. The manoeuvre was closely monitored by ESA’s mission control in Darmstadt, Germany, who followed the craft’s signals via the highly sensitive radio dish at New Norcia, Australia.
