Follow astronaut Scott Kelly’s record-breaking 12-month mission on the International Space Station, from launch to landing, as NASA charts the effects of long-duration spaceflight.
The space shuttles were intended to be a safe and cost-effective way to get into space, yet ignorance and an impending shutdown threatened that. Follow the extraordinary history of the NASA space shuttles from the 1981 maiden space flight to the televised explosion of Challenger in 1986.
Astronomer Shep Doeleman and his team are on a mission that will challenge the theories of Albert Einstein and could pave the way to a revolution in physics: to capture the first-ever image of a black hole. To do this, they must link eight multimillion-dollar observatories around the world to a spot 26,000 light years away. It's the equivalent of spotting an orange on the moon, but after 10 years of planning and the combined brainpower of over 200 international scientists, the team feels they're ready to make scientific history.

The episode, devoted to the planet Mars, begins with scientific and fictional speculation about the Red Planet during the late nineteenth and early twentieth centuries (H. G. Wells' The War of the Worlds, Edgar Rice Burroughs' science fiction books, and Percival Lowell's false vision of canals on Mars). It then moves to Robert Goddard's early experiments in rocket-building, inspired by reading science fiction, and the work by Mars probes, including the Viking, searching for life on Mars. The episode ends with the possibility of the terraforming and colonization of Mars and a Cosmos Update on the relevance of Mars' environment to Earth's and the possibility of a manned mission to Mars.
