Some twitter streams painting good coverage together: https://twitter.com/ESA_Rosetta https://twitter.com/ESA_Rosetta https://twitter.com/Philae2014 https://twitter.com/Philae2014 https://twitter.com/elakdawalla https://twitter.com/elakdawalla https://twitter.com/chrislintott https://twitter.com/chrislintott https://twitter.com/FrancescoTop https://twitter.com/FrancescoTop Also each Philae experiment seems to have a "personal" twitter account set up too, and with a short description, worth a quick reading when they link to them. Some specially noteworthy recent updates from accounts above: @elakdawalla: The sun will rise on Philae around 6:00 am UTC. It is theoretically possible it could wake up then. Next comm pass would be at around 11:00 @chrislintott: Current comms mode is 1 packet every a few minutes - but no science data left on @philae2014 - it all got uploaded! Wonderful! #cometlanding @FrancescoTop: Consert PI is confident that using tonight's data w/ previous one we can triangulate and find where #Philae is on the comet. @elakdawalla: Even if the solar panel is in a better position, it's quite possible it won't wake up tomorrow, but could recharge over days, wake later

It was immense luck all the time. Since harpoons failed, there was serious chance for lander not to remain on the comet at all, or to get seriously destroyed or disabled earlier than now. Now it seems that most (all?) of the experiments were performed. Wow. But in order to get lucky, we have to first dare to try and then invest in work. Congratulations!

  Bad luck earlier with the thruster and harpoons, and the need to hibernate the Rosetta. Good luck later with the bouncing.

    Yes, the harpoons definitely weren't the only problem in the mission. We can always imagine even better outcomes (like, bouncing but ending on a place with a lot of sunlight) but it appears it was very good even so: until recently we weren't sure if any movement would launch the lander back into space. Or if the battery would last long enough for more experiments to be done. Or the results to be sent.

@FrancescoTop is my boss! :) Lots of ups and downs over the last couple of days, but I think we can say that Philae is an unmitigated success. There's a lot been said about the problems faced, but despite that, there's been some great science data downlinked and hopefully a lot of fantastic discoveries ahead. Philae has helped shed light on a lot of outstanding issues in Solar System formation and planetary science. The hope is that this will help spur on further research and lead to more insights into the ingredients that go into the models that describe where we came from and where we're going.
