China is researching whether we can have babies in space

# China's Space Station Experiment Could Help Us Understand Risks of Having Babies in Space China is testing how human embryos develop in the weightless environment of space to figure out whether it's safe for people to have children on the moon or Mars. Scientists sent embryo-like structures made from human stem cells to their space station for five days—the critical period when organs form—to see if the lack of gravity causes birth defects. The findings could help researchers develop ways to protect future space colonists and their offspring from potential harm.
