Rosetta deputy flight director Elsa Montagnon in ESOC’s Main Control Room just announced: We acquired signals from Philae just a few minutes ago, but then lost contact again.

This has happened in two of the three previous communication passes with Philae, when initial contact was lost and then regained several times. It has taken up to an hour to establish a stable telecom link to the surface, so this is ‘normal’ behaviour.

The mission control team continues watching closely.
