An idea born in unsettled times becomes a feat of engineering excellence. The most complex machine ever built to bring humans to and from space and eventually construct the next stop on the road to space exploration.

Let us take you to one of the most thrilling journeys mankind ever made. Be close witness to the complete mission of both of the Voyager Twins and explore regions mankind never saw before. Even at date the only available material of Uranus and Neptune are the innumerable recordings taken by these probes. All scientific findings made by the Voyager Twins exercised an influence on all following probe missions and actually made them possible.

With unique access to Nasa, Brian Cox follows Perseverance rover’s search for life on Mars during a critical seven-day period as it undertakes an epic journey across the red planet.

BUILT FOR MARS: THE PERSEVERANCE ROVER goes behind the scenes at NASA’s Jet Propulsion Laboratory to follow the birth of the Perseverance rover.

200 years after Chopin's birth, the Space Shuttle Endeavour, like a giant piano, took the music of Chopin into orbit.

The film features amazing scenes of places never before seen gathered by key space missions that culminated with groundbreaking discoveries in 2015. It features a spectacular flight though the great cliffs on comet 67P, a close look at the fascinating bright "lights" on Ceres, and the first ever close ups of dwarf binary planet Pluto/Charon and its moons.

Did Mars ever have life on it? To answer this question, Europe and Russia have launched a unique and ambitious 2-stage project: ExoMars 2016-2018. This documentary is a thrilling look behind the scenes of a magnificent human and scientific adventure. We will uncover the most fascinating aspects of this mission and the search for signs of life on Mars.

An epic journey around Mars — built from real satellite and rover data — revealing the red planet as you’ve never seen it before.

In an age when misinformation, alternative facts, and conspiracy theories have become mainstream, UFOs have risen to become one of the most-talked about pop culture phenomena. With all of this noise, how can we expect anyone to know how much of this is true? What is in our skies? What do we know, and how do we know it? And most importantly: Are we being visited?

Go higher, faster and farther with the Smithsonian as they explore the dreams of flight.

The New Horizons team examines the latest findings and imagery from Pluto and the fringes of our solar system revealing a world unlike any other we've seen before.

Before the joint NASA/ESA Cassini-Huygens mission, humanity only knew what had been learned, decades earlier, with the previous limited, rapid "fly-by" Pioneer and Voyager missions. Cassini-Huygens spent more than 13 years in wildly varied orbits around Saturn, allowing the spacecraft to pass near many of its moons, as well as execute a soft-landing of its Huygens lander on the moon Titan. By mission end, it accumulated a mountain of imagery and scientific data that will continue to be studied for years to come. This film is a testament to the amazing efforts of the scientists who planned and executed the mission. It combines breathtaking images, movies, and a variety of animations to take the viewer into Saturn's complex system of rings and moons, as well as stepping viewers through some of the more exciting scientific discoveries made over the course of the elaborately complex mission.

Apollo 16 mission from NASA footage.

The first effort to send human beings to the Moon coincides during Christmastime on Earth.

Computer animation and footage from NASA space missions explain how our solar system evolved and the place Earth has within the system.

Twin astronauts Scott and Mark Kelly were separated for almost a year, undergoing intensive measurements when one was in space and one was on Earth. But that was only the beginning of their scientific odyssey. "Beyond A Year in Space," PBS and Time's follow-up documentary to last year's — which followed Scott Kelly from launch to landing — chronicles Kelly's return to life on Earth and the extensive medical testing the duo undergo to determine exactly what changes have occurred as a result of his record-breaking stay on the International Space Station. The documentary also follows two new astronauts, Jessica Meir and Victor Glover, training to go even further.
