The European Space Agency’s tiny Philae lander, which went quiet somewhere on the surface of Comet 67P/Churyumov-Gerasimenko about seven months ago, surprised mission scientists last weekend by sending home a short message saying it was alive and well somewhere on the surface of the comet. Slooh will broadcast a show on June 15, 2015 to discuss this promising event and what it means to the mission to explore the comet close up in the coming weeks and months.

The lander has been out of contact with Earth since last November after it touched down on the surface of Comet 67/P. The craft was unable to secure itself to the comet, bounced several hundred meters across the surface, and came to rest in an unknown location that shaded the Sun from its solar panels. After operating and sending data for about 60 hours, the little lander went silent. But as the comet moved closer to the Sun, more light fell on the lander’s solar panels which allowed the craft to recharge itself sufficiently to broadcast a brief message. The signal was picked up by the Rosetta orbiter, the larger craft that carried Philae to the comet. Rosetta then relayed the message to Earth.

During our live broadcast, we’ll review the dramatic events surrounding Philae’s touchdown last year, examine the many efforts mission scientists initiated to find the craft, and discuss what Philae’s second act means for the future of the science mission as the comet nears its closest approach to the Sun this August.
