Spermien werden auf einen Hindernisparcours geschickt, um die Grenzen der Weltraumkolonisierung auszutesten

***The Telegraph reports:***

Scientists have used a tiny plastic obstacle course to find out if sperm would struggle to “navigate” during sex in [space](https://www.telegraph.co.uk/space/).

Some particularly resilient sperm did make it through the course, suggesting that conceiving [children](https://www.telegraph.co.uk/children/) in space would be possible, according to research published on Thursday.

A bigger problem may be that the development of embryos after fertilisation could be harmed by a lack of gravity, researchers in [Australia](https://www.telegraph.co.uk/australia/) found.

With hopes of colonising space, scientists have been studying how difficult it would be to procreate. Next week, Nasa hopes to launch its first crewed mission around the moon in half a century.
