Scientists and modern explorers are determined to send humans to Mars; as NASA builds its first spacecraft to carry astronauts to Mars and tech visionaries devise extraterrestrial colonies, future on Mars might be a reality.
Richard Hammond takes on the ultimate engineering project. How on earth do you make a planet, or a solar system, a galaxy or even... a universe? To find out, he opens up his cosmic toolbox and builds each one piece by piece, from the top of an impossibly high tower. What does he need to construct the cosmos, and what happens if he gets it wrong? With eye-popping computer graphics, Richard discovers that it takes an entire universe to make our planet just right for us.
Discoveries about interstellar space, the space between the universe's stars, reveal that it's not empty and unremarkable as previously thought, but filled with weird objects and strange phenomena that might hold the darkest secrets of the cosmos.
