So I went ahead and actually used kdiff. Here are the relevant passage. Honestly it looks more like live rewriting of the FAQ to take into account the fact that Philae had a bumpy landing. I don't see an intention to deceive. It's awkward to present the document without mentioning it's not the detailed mission objectives. That maybe the `perfect ending` considering we have some data back and well.. it's the only ending we have so rosetta exploding before philae could even be launched might have been labeled `perfect` too because it's the first time we put something into the orbit of a duck-like comet. They certainly wished they had more philae time though. That would have been even more perfect. I wouldn't qualify this a `major failure` though (does the hostility come from that ?). > The science observations will start immediately. During the first week – the minimum mission target – a first run of the most important scientific measurements will be completed. During this phase the lander can operate on primary battery power, should this be necessary. In a second phase that is meant to last up to three months, a secondary set of observations will be conducted, using backup batteries that will be recharged by the energy from the solar cells on the lander. However, no one knows precisely how long the lander will survive on the comet. And then: > The science observations will start immediately.
