International Space Station turns 25

For the past 25 years, astronauts have lived and worked on the International Space Station to conduct research on the human body in microgravity.

Hopes are set on returning people to the moon, but scientists say there are still big gaps in the understanding of survival beyond the Earth’s atmosphere.

Within the next few weeks, astronauts will launch on a mission around the moon for the first time in 53 years.
