Neil deGrasse Tyson sets off on the Ship of the Imagination to chase a single comet through its million-year plunge toward Sol. Later, Tyson visits the birth-place of Sir Isaac Newton and retraces the unlikely friendship between Newton and brilliant polymath Edmond Halley. It was Halley's patience and generosity which allowed Newton to conquer his fear of isolation and find the courage to publish his masterwork, "Principia Mathematica" which launched a scientific revolution.

Today we are talking about the life -- and death -- of stars. Low mass stars live a long time, fusing all their hydrogen into helium over a trillion years. More massive stars like the Sun live shorter lives. They fuse hydrogen into helium, and eventually helium into carbon (and also some oxygen and neon). When this happens they expand, get brighter, and cool off, becoming red giants. They lose most of their mass, exposing their cores, and then cool off over many billions of years.

Kevin explores and probes second by second what it takes to 'lift off' into space. With Tim only days into his six-month mission, he helps Kevin answer what keeps astronauts safe and on track as they are propelled into orbit. How do you control the energy of 300 tonnes of liquid fuel? What happens to your body if you don't wear a spacesuit? And how do you catch up with a space station travelling at 17,500 mph to finally get inside? With explosive live experiments, guest astronauts in the lecture theatre, and planetary scientist Monica Grady direct from the launch pad in Kazakhstan, we learn all this and more as those thrilling minutes of lift off are recreated.
