If sleeping in is your favourite part of a holiday, this might just be your dream vacation.
In the name of space travel Nasa is looking for volunteers to sleep-in for two months.
They'll even pay you for your time.
The study into gravity's effect on the human body during sustained space travel is due to take place in Cologne, Germany, as a joint project between European Space Agency and Nasa.
While the participants will not actually travel anywhere, the experiment simulates the experience of voyaging to the stars from the comfort of bed.
