In space traveling , it can often be the flyspeck thing that ruin a big mission . That ’s why aid to item is key , particularly inside a cleanroom where ballistic capsule are put together and prepped for their rigorous journeying through the cosmos . But even those meticulously regulated rooms ca n’t keep some microorganisms out . In fact , some bacterium thrive in the stringent environment .
A chemical group of scientist at NASA ’s Jet Propulsion Laboratory , as well as other institutes in India and Saudi Arabia , distinguish 26 previously unknown bacterial mintage in the cleanroom used to put together the Phoenix spacecraft forward of its launch in August 2007 . Thediscovery , of late publish in the diary Microbiome , foreground the likely risk posed by highly resilient microorganisms that could contaminate quad missions or the planets they visit .
For the study , the team of scientist sequenced 215 bacterial strain . Some of these were present before the Phoenix spacecraft arrived at its cleanroom on April 25 , 2007 , while others formed during the spacecraft ’s meeting place and testing , and after it had been moved to the launchpad to begin its journey to Mars . Out of the 215 strains , the squad identified 53 melodic line belong to 26 new specie .

“ Our field of study aimed to understand the hazard of extremophiles being transferred in space commission and to identify which microorganisms might exist the rough condition of space , ” Alexandre Rosado , a researcher at the King Abdullah University of Science and Technology ( KAUST ) , and lead author of the study , say in astatement . “ This movement is polar for monitoring the danger of microbic taint and safeguarding against unintentional colonization of exploring planet . ”
NASA cleanrooms are rough environments for life , with cautiously controlled temperature , humidity , and airflow to keep out rubble and bacteria . The type of microorganisms that can hold up in a cleanroom may also be equipped to make it in space . Many of the newly identified micro-organism that were grow in the NASA cleanroom were especially live against decontamination and radiotherapy . The fearless bacteria carry a unique genetic defense system with traits like desoxyribonucleic acid repair , enhanced metabolism , and the ability to detox harmful atom . These niggling hombre are what Destiny ’s Child was blab about with their hit “ Survivor . ”

away from highlighting the potential encroachment of these bacteria in space , the young discovery could also have applications on Earth . “ blank travel provides an opportunity to study micro-organism that have relevant tension - resistance genes , ” Junia Schultz , a postdoctoral mate at KAUST , and first source of the study , suppose in a financial statement . “ The genes identified in these newly discovered bacterial species could be engineered for applications in medication , food for thought saving , and other manufacture . ”
NASA , it would seem , may also need to go back to the drawing control panel when it comes to its cleanroom design .
