Philae comet lander wakes up
Source: BBC
The European Space Agency (Esa) says its comet lander, Philae, has woken up and contacted Earth.
Philae was dropped on to the surface of Comet 67P by its mothership, Rosetta, last November.
It worked for 60 hours before going to sleep when its solar-powered battery ran flat.
BBC Science Correspondent Jonathan Amos says the comet has since moved nearer to the sun and Philae has enough power to work again.

(10,857 posts)It hasn't been picked up by phys.org yet, which is my gold standard of "probably not bullshit."
But if it has actually happened and ESA is getting data back, then that mission just massively increased the amount of Science points it will be awarded in Kerbal Space Program.

For 85 seconds Philae "spoke" with its team on ground, via Rosetta, in the first contact since going into hibernation in November.
When analysing the status data it became clear that Philae also must have been awake earlier: "We have also received historical data - so far, however, the lander had not been able to contact us earlier."
Now the scientists are waiting for the next contact. There are still more than 8000 data packets in Philaes mass memory which will give the DLR team information on what happened to the lander in the past few days on Comet 67P/Churyumov-Gerasimenko.

(10,857 posts)My father the Apollo rocket scientist is more amazed and fascinated by this mission than any of the other totally amazing missions ongoing, including but not limited to:
Lunar Reconnaissance Orbiter:

Dawn Mission to Vesta and Ceres:

New Horizons to Pluto:

There may not be another year of space science like this one for decades to come.

(129,053 posts)I pretty much gave up on that based on where and now it landed on the comet. Let's just hope that some unmapped piece of rock or debris doesn't impact with the comet.

Also, as in my response in that thread, Universe Today covered that particular story.
Have We Found Rosetta's Lost Philae Lander? There are plenty of pics at the link a couple of which I included in the DU thread above. Reproduced here.
The five candidates, all but the upper left were rejected.
The smoking gun:
The October 22 image was before Philae landed.
Is this Philae?

(101,320 posts)They catch the light, but I don't think they're enough to budge the lander, unless it was incredibly finely balanced.

(49,002 posts)Yes, there was some luck. But it is good engineering that created the autonomous system that collects such power as it is able and calls home. Good engineering foresight that things can go wrong and to plan for such events.

The historic space probe has sent signals to Earth, ending seven months of silence
By Celeste Biever, Elizabeth Gibney and Nature magazine | June 14, 2015
Philae, the space probe that made history when it landed on a comet in November 2014, is awake. The European Space Agency (ESA) announced today (June 14) that it had received signals from the comet lander last night, at 22:28 Central European Standard Time. They were the first in over seven months.
Excited scientists on the mission told Nature that Philae has probably been awake for a few days and that they hope the lander will start some low-risk science activities in the coming daysassuming that Philae makes contact again.
"Philae is doing very well: It has an operating temperature of -35ºC and has 24 Watts available," said ESA project manager Stephan Ulamec of the German Aerospace Centre (DLR) near Cologne, according to an ESA statement. "The lander is ready for operations."
ESA says that for 85 seconds Philae spoke with ESA ground control via the spacecraft Rosetta, which is orbiting 67P.
