What does Philae do during descent?

Infographic to summarise the measurements carried out by Rosetta’s lander, Philae, during its seven-hour descent to Comet 67P/Churyumov–Gerasimenko and immediately after touchdown. The time the signal is expected on Earth to confirm separation (09:03 GMT) and approximate time of landing confirmation (16:00 GMT) is also provided. The lander operations are listed in alphabetical order. After touchdown measurements have been made, the lander begins the first science sequence operations (not shown in this infographic).
