Worms in space: The Molecular Muscle Experiment
It sounds like a mad sci-fi adventure but scientists are preparing to fly worms into space!
It’s part of a serious experiment to try and understand why astronauts lose some of their muscle in space.
During spaceflight an astronaut’s body changes. Losing muscle can affect their ability to work on a long space mission. Astronauts can lose up to 40% of their muscle after 6 months in space.
The very small worms, which can only be clearly seen under a microscope are known as C. elegans. It seems incredible but in many ways the tiny worms are similar to humans and share some of the essential biological characteristics. The worms help show the effect of changes in space, including alterations to muscle and the ability to use energy.
Their journey to the International Space Station will begin at the Kennedy Space Centre in Florida, USA. The International Space Station is in orbit around earth between 205 and 270 miles away. The worms will reproduce in space and after growing to adults, in around 6.5 days, they will be frozen until return to Earth.
UK scientists from Exeter and Nottingham Universities are working together on the experiment with a launch date expected November 2018
Understanding the causes of muscle loss in space may help astronauts in the future and address health problems on earth. Muscle loss caused by ageing might be better understood and the research could improve treatments for conditions such as diabetes.
The project is a real team effort and is supported by The European Space Agency, UK Space Agency, BBSRC, MRC, and Arthritis Research UK.
