Our space microbes flew to the ISS on April 19th, 2014. Check out the microbes that flew here, read about the results of the "Microbial Playoffs" here, and see how the microbes grew in space compared to earth here! NASA also maintains a page describing the project here.
Still to come is our analysis of the microbes already living on the International Space Station (publication in November 2017), and our analysis of the 3000 cell phone and shoe samples taken from participants in Project MERCCURI.
-Here's a paper describing a new species of bacteria (Porphyrobacter mercurialis... get it?) that we discovered during this project, and that we sent to the ISS. And here's the paper describing the genome of that species.
