Thousands of microscopic worms grown at the University of Exeter are due to blast off in a space rocket today for research into the human ageing process.
The multi-million pound project is the first UK-led experiment to the International Space Station.
Scientists from Exeter say the 36,000 nematodes will spend a week in an incubator before they die and then will be frozen and examined on their return to earth.
The worms are being used because they have a similar muscle structure to humans.
Researchers hope studying them could help people with conditions including muscular dystrophy and diabetes.
The probe has already taken its first picture from the surface of the red planet.
