A giant new Moon rocket built by NASA has been revealed to the public for the first time in Florida, in the USA.
The rocket is a new design that is known as the Space Launch System (SLS).
If it gets through a final round of tests on time, this SLS will send an uncrewed test capsule around the Moon within a couple of months.
The 100 metre-tall vehicle is part of Nasa’s Artemis programme that aims to return astronauts to the Moon’s surface sometime in the second half of this decade.
What will the SLS rocket do?
The Space Launch System – or SLS – is designed to be able to send enough cargo to the Moon. This means that astronauts will be able to stay there for longer periods.
The Space Launch System is the only rocket capable of sending humans into deep space. It is the most powerful rocket in the world and during lift-off, it will produce 8.8 million pounds of thrust.
Altogether the programme is set to cost around $45milion NZ dollars.
The last time a person landed on the Moon was in 1972.
