250 miles up into outer space, the International Space Station (ISS) hurtles silently around Earth at about 5 miles per second. Inside, scientific experiments are constantly underway, from harvesting lettuce to studying what living a year in space does to the human body. One particular study, conducted by the European Space Agency (ESA) and concluded last month, has found that two species of tiny fungi originally from Antarctica have survived living in Mars-like conditions for a period of 18 months. These results could prove critical in the efforts to find an answer to the question immortalized by David Bowie: Is there life on Mars? The findings were published in the journal Astrobiology.

David Bowie, the pioneering English musician who transcended genres with hits ranging from "Space Oddity" to "Changes," "Heroes," and many, many, more, died yesterday at age 69 after fighting cancer for 18 months, according to a statement on his official Facebook page.

Despite the tragic news about David Bowie, the number of people dying from cancer every year has dropped to its lowest rate since 1991, according to a new study from the American Cancer Society and reported by Stat News.

International Space Station Expedition 35 Commander Chris Hadfield has taught us so much about space. He's shown us how to make sandwiches in zero gravity (with tortillas, because bread crumbs - like potato chip crumbles - can clog the instruments) and why there's no crying in space travel. And now, with his departure from the ISS imminent, he's shown us that covers can still be cool by releasing a video of himself performing David Bowie's "Space Cowboy" aboard the ISS.
