Migrating Microbes
With every spacecraft that leaves Earth, millions of microbes hitch a ride into space. As astrobiologists search for life in other worlds, preventing forward and back contamination remains a key priority. This will be vital in future missions, such as NASA’s Mars Sample Return. NASA’s planetary protection program is working to improve procedures to make sure hitchhiker microbes traveling on robotic or crewed vehicles don’t contaminate new worlds.
