The two Nasa astronauts overstaying on the ISS aren't the first to be stuck in space… and they probably won't be the last.

As big as a football field and heavier than 200 elephants, de-orbiting the ISS represents a monumental challenge. But is there another future for the space station?

China's Chang'e-6 mission is intended to bring back lunar samples but is also a stepping stone to much more ambitious space exploration.

Astronauts living on the Moon will need lots of power – but they can't take fuel supplies with them. A new generation of miniature nuclear reactors could be the answer.
