This week in Science Saturday: Welcome the Mars 500 crew out of their 520-day simulated Mars mission, watch a huge asteroid whiz close by Earth, add three elements to the periodic table, and find alien life by searching for night lights. All this and more, plus our (weird) gadget of the week: the USB eye warmer.
