Genetically-enhanced 'mighty mice' will be launched to the International Space Station today

Genetically-edited'mighty mice' are being sent up to the International Space Station today as experts investigate how to limit muscle and bone loss in low gravity. Tweaked to have enhanced muscle growth, the ripped rodents will ride on-board a ship being launched by Elon Musk's rocket company, SpaceX. The mission had been scheduled to launch yesterday, but rough winds detected in the upper atmosphere forced a one-day delay for safety reasons. Lift-off of the Falcon 9 rocket is now expected to take place at 12:29 EST (19:29 GMT) from NASA's Kennedy Space Center in Florida. It's'Dragon' capsule will go on to dock with the space station on Sunday.
