Sometime in the far future, humans develop the power to build worlds. Game of Thrones fans will recognize Aiden Gillen as the teacher. His apprentice is played by Aisling Franciosi. The Rosetta orbiter is still following Comet 67P on its way around the Sun. The Philae lander has an electrical starvation problem. It successfully landed on the sunny spot chosen as its best location, but it bounced off the surface of the comet twice and landed in a shady area that gets only 1.5 hours of sunlight every Earth day. That’s not enough sunlight to recharge Philae’s batteries, so the washing-machine-sized probe ran through its primary scientific tasks as quickly as possible before it went dark. Philae was able to drill into the surface and analyze the composition of the sample. It relayed that data to Rosetta, which then forwarded it to Earth. Planetary scientists are intensely interested in the results, as it could provide clues about the formation of the solar system and Earth. For its part, Rosetta has discovered that comets stink. Literally.
