The possibility of a human civilization on Mars has seemed like a fantasy -- until now. We go behind-the-scenes at SpaceX, where Elon Musk shows us just how real this fantasy can be.
Before moving on from Jupiter to Saturn, we’re going to linger for a moment on Jupiter’s moons. There are 67 known moons, and 4 huge ones that we want to explore in greater detail. Ganymede is the largest - larger, in fact, than any other moon in the solar system and the planet Mercury! Callisto, orbiting the farthest out, is smaller but quite similar to Ganymede in many ways. Io, meanwhile, is most noteworthy for its tremendous volcanic activity. There’s also water on Ganymede and Europa!
There is a hellish planet in our solar system; covered in thick dense clouds and roasted by colossal temperatures. Incredibly this is a vision of Earth's future. To understand how our world will be destroyed we need to look at Earth's evil twin Venus.
Twelve billion miles away a tiny spaceship is leaving our solar system and entering the void of deep space. It is the first human-made object ever to do so. Slowly dying within its heart is a plutonium generator that will beat for perhaps another decade before the lights on Voyager finally go out. But this little craft will travel on for millions of years, carrying a Golden Record bearing recordings and images of life on Earth. The story of Voyager is an epic of human achievement, personal drama and almost miraculous success. Launched 16 days apart in 1977, the twin Voyager space probes have defied all the odds, survived countless near misses and almost 40 years later continue to beam revolutionary information across unimaginable distances. With less computing power than a modern hearing aid, they have unlocked the stunning secrets of our solar system. This film tells the story of these magnificent machines, the men and women who built them and the vision that propelled them farther than anyone could ever have hoped.
While Jupiter is nowhere near massive enough to initiate fusion in its core, there are even more massive objects out there that fall just short of that achievement as well called brown dwarfs. Brown dwarfs, have a mass that places them between giant planets and small stars. They were only recently discovered in the 1990’s, but thousands are now known. More massive ones can fuse deuterium, and even lithium, but not hydrogen, distinguishing them from “normal” stars. Sort of.
Kevin explores the next frontier of human space travel. Live from the Station, Tim answers questions directly from the children in the lecture theatre audience. With Tim's help out in Earth's orbit, Kevin investigates how the next generation of astronauts will be propelled across the vast chasm of space to Mars and beyond. So, how will life be artificially sustained as we travel the millions of kilometres to the red planet and on into the cosmos? How will our food last for three years or more? And what is waiting what for us when we finally land? With earth-shattering experiments, top space scientists and our astronaut live from space, Dr Fong reveals how we'll survive that voyage to space's next frontier and beyond.
