In the last month of the space shuttle programme, Kevin Fong is granted extraordinary access to the astronauts and ground crew as they prepare for their final mission. He is in mission control as the astronauts go through their final launch simulation, and he flies with the last shuttle commander as he undertakes his last practice landing flight. Kevin also gains privileged access to the shuttle itself, visiting the launchpad in the company of the astronaut who will guide the final flight from mission control.
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.
Harvard professor and best-selling author, Dr. Lisa Randall, simplifies and expounds upon some of modern physics' most basic questions. What is dark matter and dark energy? What is the fundamental nature of space and time? What do we not know yet about the universe and its fundamental properties?
Today Phil helps keep you from ticking off an astronomer in your life by making sure you know the difference between a meteor, meteorite, and meteoroid. When the Earth plows through the stream emitted by a comet we get a meteor shower. Meteors burn up about 100 km above the Earth, but some survive to hit the ground. Most of these meteorites are rocky, some are metallic, and a few are a mix of the two. Very big meteorites can be a very big problem, but there are plans in the works to prevent us from going the way of the dinosaurs.
