Astronauts can now sequence microbes they find on the International Space Station (ISS) without having to send them back to Earth:

Being able to identify microbes in real time aboard the International Space Station, without having to send them back to Earth for identification first, would be revolutionary for the world of microbiology and space exploration. The Genes in Space-3 team turned that possibility into a reality this year, when it completed the first-ever sample-to-sequence process entirely aboard the space station. Results from their investigation were published in Scientific Reports [open, DOI: 10.1038/s41598-017-18364-0] [DX].

The ability to identify microbes in space could aid in the ability to diagnose and treat astronaut ailments in real time, as well as assisting in the identification of DNA-based life on other planets. It could also benefit other experiments aboard the orbiting laboratory. Identifying microbes involves isolating the DNA of samples, and then amplifying – or making many copies - of that DNA that can then be sequenced, or identified.

The investigation was broken into two parts: the collection of the microbial samples and amplification by Polymerase Chain Reaction (PCR), then sequencing and identification of the microbes. NASA astronaut Peggy Whitson conducted the experiment aboard the orbiting laboratory, with NASA microbiologist and the project's Principal Investigator Sarah Wallace and her team watching and guiding her from Houston.

Now Russian cosmonauts can test their crazy ideas. At least, until the ISS gets split apart and deorbited.

    when do we send Sigourney Weaver up?

    I don't remember her in Annie Hall. I'm going to have to watch again
