Thinking of taking that vacation to space anytime soon? This series examines what it might entail, from the drastic climate shifts to the stunning sights, by bringing viewers up close with these distant worlds via advanced animation. Back on Earth, extreme environments, such as Hawaii's volcanoes or the Atacama Desert in Chile, are visited by NASA scientists to approximate what a trip to the other planets might be like. Segments also include a preview of a soon-to-launch space probe to Jupiter, and what the first manned mission to Mars will be like.

Mankind's exploration of the planet Jupiter.

When people think of American space travel, the first names that come to their minds are usually the likes of Buzz Aldrin, Neil Armstrong and Sally Ride. Like with most massive projects like NASA's, there are a number of people behind the scenes who work tirelessly to get to the point where astronauts can go into space. Those people, however, aren't household names like the folks who blast off on the space shuttles. This series profiles the secret heroes, engineers who helped build the spacecraft and other instruments that have allowed astronauts to launch into space to explore the world beyond what's visible from Earth. The show reveals the stories behind how they created such machines as the Saturn V moon rocket and the Hubble Space Telescope.

A new breed of explorer has taken space travel beyond the moon to unlock and reveal first-ever views of alien worlds and cosmic bodies far beyond anyone's imagination. "Space's Deepest Secrets" shares stories of the men and women who pushed their ingenuity and curiosity to uncover some of the most groundbreaking findings in the history of space exploration. Hourlong episodes cover NASA's New Horizons mission to Pluto, the Hubble Telescope, the twin Voyager explorations, and other past, current and future missions and projects.

The space probes, and their parents back on Earth, explore our solar system.

Theoretical physicist, author, broadcaster and professor Jim Al-Khalili sets out to discover the background of the rules of the universe and how humans discovered them. Al-Khalili investigates the laws that link everything, the concepts of energy, and how the concept of information relates to today's reality. Energy is vital to everything living, but what exactly is it? Out to answer this question, Al-Khalili proves how energy is so crucial to daily existence and its link to understanding the entire universe.

This co-production of the BBC and the Science Channel is hosted by physicist Brian Cox ("Wonders of the Universe"), who is fascinated by the wonders of our planet and the laws of nature that created them. In this five-part series he travels the globe to examine some of the most compelling phenomena, demonstrating the power of the sun as he watches a total solar eclipse in India and the Aurora Borealis in Norway. In addition to the breathtaking footage, viewers can learn about the power of the forces of nature and their impact on the planet in this Peabody Award-winning documentary series.
