Update from the press conference: did the asteroid lander bounce?
From the press conference that wrapped up a few minutes ago:
Philae lander manager Stephan Ulamec cautioned that it's "very complicated to understand what has happened during this landing after this landing." Although Philae reported back both housekeeping and science data, it's scarce enough that the team has to make some inferences.
Based on fluctuations in the radio link and in solar power generation, one speculation is that the craft may have lifted off again after landing, done a somersault, and settled back to the surface. "Maybe today, we didn't just land once, we even landed twice," Ulamec said.
The lander is out of radio contact at the moment, but that's not surprising because its landing site has now rotated to face away from the Sun, he said. Assuming the probe reconnects in the morning, the science team should learn more then, he said.
