Rest Stop
A quarter slice of lime in my iced water.
The stool at the bar has the perfect height for soup.
Farthest left seat so I can lean against the wall.
Little things.
Listening to three different languages being spoken at once.
Cacophony of culture.
Nothing more gorgeous.
Cute barista that smiles.
Try to hide my blush.
Sip.
Drink.
Cash.
Out.

The As, Gs, Cs and Ts of the Space Station: First In-Space Microbe Identification
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 totally amazing for the world of microbiology and space exploration.
Tumblr media
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.
The ability to identify microbes in space could aid in the ability to diagnose and treat astronauts in real time, as well as assisting in the identification of life on other planets. It could also benefit other experiments aboard the space station.
HELPFUL SCIENCE HINT: Identifying microbes involves isolating the DNA of samples, and then amplifying – or making lots and lots (and LOTS) of copies - of that DNA that can then be sequenced, or identified.  
As part of regular monitoring, petri plates were touched to various surfaces of the space station. NASA astronaut Peggy Whitson transferred cells from growing bacterial colonies on those plates into miniature test tubes, something that had never been done before in space (first OMG moment!).
Tumblr media
Once the cells were successfully collected, it was time to isolate the DNA and prepare it for sequencing, enabling the identification of the unknown organisms – another first for space microbiology.
Enter Hurricane Harvey. *thunder booms*
Tumblr media
“We started hearing the reports of Hurricane Harvey the week in between Peggy performing the first part of collecting the sample and gearing up for the actual sequencing,” said Sarah Wallace, the project’s primary investigator.
When our Johnson Space Center (JSC) in Houston became inaccessible due hurricane conditions, Marshall Space Flight Center’s Payload Operations Integration Center in Huntsville, Alabama worked to connect Wallace to Whitson using Wallace’s personal cell phone.
With a hurricane wreaking havoc outside, Wallace and Whitson set out to make history.
Tumblr media
The data were downlinked to the team in Houston for analysis and identification.
“Once we actually got the data on the ground we were able to turn it around and start analyzing it,” said Aaron Burton, the project’s co-investigator. “You get all these squiggle plots and you have to turn that into As, Gs, Cs and Ts.”
Those As, Gs, Cs and Ts are more than just a nerdy alphabet – they are Adenine, Guanine, Cytosine and Thymine – the four bases that make up each strand of DNA and can tell you what organism the strand of DNA came from. 
Tumblr media
“Right away, we saw one microorganism pop up, and then a second one, and they were things that we find all the time on the space station,” said Wallace. “The validation of these results would be when we got the sample back to test on Earth.”
Soon after, the samples returned to Earth aboard the Soyuz spacecraft, along with Whitson.
With the samples now in the team’s JSC lab, tests were completed in ground labs to confirm the findings from the space station. They ran the tests again and again, and then once more, to confirm accuracy. Each time, the results were exactly the same on the ground as in orbit. (second OMG moment!)
Tumblr media
“We did it. Everything worked perfectly,” said Sarah Stahl, microbiologist.
This capability could change future space exploration.
“As a microbiologist,” said Wallace, “My goal is really so that when we go and we move beyond ISS and we’re headed towards Mars or the moon or wherever we are headed to, we have a process that the crew can have that great understanding of the environment, based on molecular technology.”
