Astronaut

The first Space Shuttle was originally going to be named Constitution. US President Gerald Ford agreed to rename it Enterprise – here's how Star Trek fans persuaded him.

In 1975, a meet-up between American and Soviet spacefarers in orbit showed that the superpowers could work together. Its positive effects led to the International Space Station.

When astronauts land on the Moon again as part of the Artemis project, they will have to build a place to live in. Nasa wants them to build as much of it they can from used materials.

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.

The Apollo astronauts' links to Earth were primitive compared to those we enjoy today. The next generation of moonwalkers may have a far more high-resolution way of keeping in touch.
