Antibiotic resistance is a growing problem on Earth – and it could occur in space too. Bacteria exposed to trace quantities of an antibiotic while growing in simulated microgravity developed resistance to the drug. What’s more, they retained that resistance for more than 100 generations after the antibiotic was removed.

With talk about future crewed missions to the moon and Mars, biologists are keen to know more about how microbes behave in space. What’s of particular concern is evidence that microgravity, radiation exposure and …
