Since #Rosetta’s #lander Philae first woke up from hibernation and called ‘home’ on 13 June, the teams at the Lander Control Center (LCC – DLR), the Science #Operations and Navigation Center (SONC – CNES), the Max-Planck Institute (MPS – Göttingen) and the Institute for Particle and Nuclear Physics (Wigner Research Centre for Physics – Budapest) have been working with ESA’s #rosetta Mission Operations Centre (RMOC – ESOC) and the Rosetta Science Ground Segment (RSGS – ESAC), and in close cooperation with the Philae and Rosetta scientists, to establish regular and predictable contacts with Philae, and to resume scientific measurements. This blog post has been written by Koen Geurts, Philae technical manager, and Cinzia Fantinati, Philae operations manager (both from the LCC at DLR), and gives a (...)

New communication with #Philae – commands executed successfully

This report is provided by the German Aerospace Center, DLR. The #philae #lander communicated with the #Rosetta orbiter again between 19:45 and 20:07 CEST on 9 July 2015 and transmitted measurement data from the COmet Nucleus Sounding Experiment by Radiowave Transmission (CONSERT) instrument. Although the connection failed repeatedly after that, it remained completely stable for those 12 minutes. “This sign of life from Philae proves to us that at least one of the lander’s communication units remains operational and receives our commands,” said Koen Geurts, a member of the lander control team at DLR Cologne. The mood had been mixed over the last few days; Philae had not communicated with the team in the DLR Lander Control Center (LCC) since 24 June 2015. After an initial test command to turn (...)
