The rival superpowers are ramping up preparations for a crewed lunar landing nearly six decades after the first moon walk

The world watched earlier this month as Nasa sent four astronauts around the moon – but to actually land on the surface the US is once again in a space race, this time with China. And China may well win.

Both countries plan to build inhabited lunar bases – the first settlement on another celestial body – as well as searching for rare resources and using the deep space environment to test technology for future crewed missions to Mars.
