Embryos growing in space a 'giant leap'

Chinese mission shows cells can multiply, but colonization of the cosmos has a 'long way to go'

The latest results from experiments aboard China's SJ-10 recoverable satellite prove for the first time that early-stage mammal embryos can develop in space.

China launched the country's first microgravity satellite, SJ-10, on April 6. The return capsule will stay in orbit for several more days before heading back to Earth. An orbital module has been used to carry out experiments.
