Space Station 3D

Some 220 miles above Earth lies the International Space Station, a one-of-a-kind outer space laboratory that 16 nations came together to build. Get a behind-the-scenes look at the making of this extraordinary structure in this spectacular IMAX film. Viewers will blast off from Florida's Kennedy Space Center and the Baikonur Cosmodrome in Russia for this incredible journey -- IMAX's first-ever space film. Tom Cruise narrates.

Death Dive to Saturn

After decades of amazing discoveries, spacecraft Cassini embarks on its final - and most daring - mission: a dive below Saturn's rings.

The Dream Is Alive

The Dream Is Alive takes you into space alongside the astronauts on the space shuttle. Share with them the delights of zero gravity while working, eating and sleeping in orbit around the Earth. Float as never before over the towering Andes, the boot of Italy, Egypt and the Nile. Witness firsthand a tension-filled satellite capture and repair and the historic first spacewalk by an American woman.

James May on the Moon

Top Gear presenter James May presents this informative program that examines the historic moon missions. Traveling to America, May meets three of the men who walked on the surface of the moon, learning how it felt and how the now antiquated technology was used to achieve such an historic feat.

How William Shatner Changed The World

William Shatner presents a light-hearted look at how the "Star Trek" TV series have influenced and inspired today's technologies, including: cell phones, medical imaging, computers and software, SETI, MP3 players and iPods, virtual reality, and spaceship propulsion.

Magnificent Desolation: Walking on the Moon

Twelve men who belong to one of the world's most exclusive fraternities -- people who've walked on the surface of the moon -- are paid homage in this documentary. Using newsreel footage, rare NASA photographs, and digitally animated re-creations, Magnificent Desolation: Walking on the Moon examines the Apollo missions between 1969 and 1972 which put astronauts on the moon.

The Pathfinders

It started with an order to land something on Mars - cheaply. In NASA's new era of "faster, better, cheaper," this mission had to create a radically different way of building a spacecraft. "The Pathfinders" tells the story of a small group of JPL'ers who dismissed warnings that a cut-rate mission to Earth's distant neighbor would cut short their careers. With a Martian parachute that could not be tested in Earth's atmosphere, and the last-minute addition of a remote controlled vehicle that would not look out of place in a toy store, the Pathfinder mission was a doubter's dream. Vet the future prospects of JPL and of a Mars program in its infancy, depended on bouncing successfully onto the rocky Red Planet and releasing a curious six-wheeled wanderer, in hopes of starting a revolution in space exploration.

Alien Moon

Our enigmatic moon may have a sinister origin that mankind is not prepared for. From astronaut UFO encounters, to flashing lights, to geometric anomalies on the surface that appear to be structures, it's possible that the moon my actually be the home of ancient aliens or be serving as a base of operations. For the moon to be able to perfectly eclipse the sun is a mathematical impossibility based on our current understanding of psychics but we also know that the moon could be hollow from experiments performed on Apollo missions. Clearly, there is an intelligence involved with our mysterious satellite.

The Wonder of It All

The Wonder of it All focuses on the human side of the men behind the Apollo missions through candid interviews with seven of the Apollo astronauts: Buzz Aldrin, Alan Bean, Edgar Mitchell, John Young, Charles Duke, Eugene Cernan and Harrison Schmitt. They all reflect on the training, the tragedies, the camaraderie, and the effect that their space travel has had on their families.

Asteroid Hunters

Venture into deep space for a fascinating look at asteroids, their cosmic origins and the potential threat they pose to our world. Written and produced by Phil Groves, produced by Jini Durr and directed by W.D. Hogan, Asteroid Hunters introduces asteroid scientists – the best line of defense between Earth and an asteroid’s destructive path – and reveals the cutting-edge tools and techniques they use to detect and track asteroids, and the technology that may one day protect our planet. The effects of an asteroid impact could be catastrophic and while the current probability of an event in our lifetime is low, the potential consequences make the study of asteroids an incredibly important area of scientific research. Witness the latest in planetary defense and how science, ingenuity and determination combine to explore the world’s most preventable natural disaster.

Woman in Motion

Nichelle Nichols' daunting task to launch a national blitz for NASA, recruiting 8,000 of the nation's best and brightest, including the trailblazing astronauts who became the first African American, Asian and Latino men and women to fly in space.
