Lunar days are about 14 Earth days long, and when night comes, temperatures plummet. But there are other issues to deal with as well. For instance, how can we overcome the moon's lack of atmosphere; difficult terrain with abrasive particles, and the effects of cosmic background radiation?

When Apollo astronaut Gene Cernan stepped on the Moon in December 1972 he left his footprints and his daughter's initials in the lunar dust. Only now, over forty years later, is he ready to share his epic but deeply personal story of fulfillment, love and loss. Cernan's burning ambition carried him from a quiet Chicago suburb to the spectacular and hazardous environment of space, and ultimately, to the Moon. Five years in the making, The Last Man on the Moon unveils a wealth of rare archive material, and takes Cernan back to the launch pads of Cape Kennedy, to Arlington National Cemetery and to his Texas ranch, where he finds respite from a past that refuses to let him go.

Almost everything we know today about the beautiful giant ringed planet comes from Cassini, the NASA mission that launched in 1997 and arrived at Saturn in 2004. Since then, the space probe has been beaming home miraculous images and scientific data, revealing countless wonders about the planet, its rings and 62 moons - including some that could harbor life. As the mission approaches its final days in 2017, it attempts one last set of daring maneuvers - diving between the innermost ring and the top of Saturn's atmosphere. Aiming to skim less than 2000 miles above the cloud tops, no spacecraft has ever gone so close to Saturn, and hopes are high for incredible observations that could solve major mysteries about the planet's core. But such a daring maneuver comes with many risks and is no slam dunk. In fact, slamming into rocks in the rings is a real possibility. Join NASA engineers for the tense and triumphant moments as they find out if their bold re-programming has worked, and discover the wonders that Cassini has revealed over the years.
