A robot diving machine will be finding out what secrets lie at the bottom of the Antarctic ocean when it starts its mission in January.
The machine, called Isis, can travel a whopping four miles beneath the sea and can travel along the seabed.
Researchers want Isis to help them find out about the animals that live in the depths of the Antarctic deep, and about the effects of glaciers on the seabed.
The mission starts in January and will last about three weeks.
Isis is the first deep-diving machine in the UK which can be controlled away from the vessel, so it's a bit like a remote-controlled robot.
