Space is the next frontier for us humans and all efforts are on to make it safe for astronauts. NASA is conducting study on its International space station to identify the microbes on board the international space station. It is as big news as it will help us to diagnose the sort of ailments astronauts are susceptible to, as well as how microbes survive in microgravity and maybe even pinpoint alien life. There examinations were earlier held on earth but there was the problem of contamination of the samples that were taken from space. It’ll be an especially important technique when humans go beyond to other planets, the earliest likely being Mars.
