![]() In 2017, that tool was used again for Genes in Space-3, as NASA astronaut Peggy WhitsonĬollected and tested samples of microbial growth from around the station.Īstronauts also tested miniPCR, a thermal cycler used to perform the polymeraseĬhain reaction. Tool was used to sequence DNA in space for the first time with Rubins at the helm. The MinION sequencer and a Surface Pro 3 tablet for analysis, the Testing took off in 2016 with the Biomolecule Sequencer. Suite of tabletop and palm-sized tools including MinION, miniPCR, and Wet-Lab-2, and more tools and processes on the Rubins said in a 2016 downlink with the National Institutes of Health. Generation to allow for more agile testing in space,” NASA astronaut and molecular biologist Kate Get machines to be compact, portable, robust, and independent of much power That has changed in a few short years as we’ve worked to find new solutionsįor rapid in-flight molecular testing aboard the space station. Fun science pro tip:Īmplification means to make lots and lots of copies of a specific section of The station, so previous research samples requiring DNA amplification and sequencing had to be stored in space until theyĬould be sent back to Earth aboard a cargo spacecraft, adding to the time Those are two characteristics that can be difficult to support aboard Molecular research equipment is large and requires significant amounts of power Unknown microbes in spacecraft, humans and the deep space locations we hope to Microgravity’s impact on living organisms and could also offer ways to identify Studying DNA in space could lead to a better understanding of The microscopic size of DNA, however, can create some big challenges for studying it aboard the International Space Station. ![]() What do astronauts, microbes and plants all have in common? Each relies on DNA – essentially a computer code for living things – to grow and thrive. Studying DNA Aboard the International Space Station of Physiology and Biophysics, Associate Professor spacestation station dna Space Center, Microbiologist and Project ManagerĬornell Medicine Dept. Space Center, Planetary Scientist and Principal Investigator Questions during a Reddit Ask Me Anything on /r/science on Wednesday, Sept. The investigation, who will be available for More questions about how the Biomolecule Sequencer works, or how it couldīenefit Earth or further space exploration? Ask the team of scientists behind In Houston hit the one-billionth-base-pairs-of-DNA-sequenced mark. 14, Rubins and the team of scientists back at NASA’s Johnson Space Center The first DNA sequencing was conducted on Aug. Return samples to Earth and await ground-based analysis. Identify microbes, diagnose infectious disease and collect genomic and geneticĭata concerning crew health, without having to wait long periods of time to Minutes from the application of the sample.Īnalysis capabilities aboard the space station could allow crews to Other terrestrial instruments whose sequencing run times can take days, thisĭevice’s data is available in near real time analysis can begin within 10-15 Microwave-sized sequencers used on Earth, and uses much less power. The tiny, plug and play sequencer is diminutive compared to the large The MinION is about the size of a candy bar, and plugs intoĪ laptop or tablet via USB connection, which also provides power to the device. (Image Credit: Oxford Nanopore Technologies) Not sequenced, and there are no immediate plans to sequence human DNA in space. Was used to sequence the DNA of bacteria, a virus and rodents. MinION (min-EYE-ON), manufactured by Oxford Nanopore Technologies in the UK, A small, commercial, off-the-shelf device called Sequencing on the space station as part of the Biomolecule Scientists considerĪstronaut Kate Rubins, who has a background in genomics, conducted the Sequence the DNA of living organisms in space opens a whole new world of ![]() International Space Station, Earth’s only orbiting laboratory.
