A new study has been found that on the survival of microbes on NASA's International Space Station(ISS). According to the report it has been found that bacteria cultured in microgravity exposed to common antibiotics were found changing their shape. Also, the bacteria is growing smaller cell volumes and thicker membranes, which made them far more resilient. Researchers has raised multiple concern if humanity is ever to become an interstellar space faring species. The E. coli bacteria were sent to the International Space Station in 2014 as part of an experimental project headed by CU Boulder’s Bio Serve Space Technologies.
