Beginning with the origins of the universe in the Big Bang, Sagan describes the formation of different types of galaxies and anomalies such as galactic collisions and quasars. The episodes moves further into ideas about the structure of the Universe, such as different dimensions (in the imaginary Flatland and four-dimensional hypercubes), an infinite vs. a finite universe, and the idea of an oscillating Universe (similar to that in Hindu cosmology). The search into other ideas such as dark matter and the multiverse is shown, using tools such as the Very Large Array in New Mexico. Cosmos Update shows new information about the odd, irregular surfaces of galaxies and the Milky Way perhaps being a barred spiral galaxy.

The film, which follows a group of teens at NASA's space camp as they learn about the science and technology behind a trip to Mars, also features commentary by science popularizers Bill Nye, Neil deGrasse Tyson, Michio Kaku; astronaut Suni Williams, and Andrew Weir, author of The Martian. But it's not the grownups who make the film; none of them, with the exception of Williams, has any shot at all of walking on Mars. It's the kids, who can dream that dream, who are the deserved focus of the narrative.

Kevin explores life in orbit on board the Station. As Tim settles in to his new home he sends special reports about what it takes to live and work in space. Four hundred kilometres above the Earth, hurtling at a speed of 17,500mph, astronauts' bones and muscles waste away, the oxygen they breathe is artificially made, and they face constant threats from micrometeorites, radiation and extreme temperatures. If a medical emergency strikes, Tim is a very long way from home. In its 15-year lifetime, the International Space Station has never had a major accident. With a British astronaut in orbit, gravity-defying experiments and guest astronauts in the lecture theatre, Dr Fong shows us how to survive life in orbit.
