NASA has detailed a new study that has uncovered the exact microbial “fingerprints” astronauts left on the International Space Station. According to the study, microbes transferred from the astronaut’s body to the International Space Station environment retain a close resemblance to their source, and scientists were able to determine which part of the astronaut’s body they came from.
There are many microorganisms on the human body, many of which are beneficial or harmless to health, and they are transferred to places where people live. NASA has conducted a series of experiments involving microbes on the International Space Station, which are designed to monitor potentially harmful things.
In its latest press release on the subject, NASA explained that researchers were able to use microbes to determine when astronauts would arrive at the International Space Station and return to Earth. Using microbial samples taken from an astronaut who worked on the International Space Station, the researchers found that surface samples taken from different parts of the International Space Station were most similar to those taken from astronauts’ skin samples.
After the astronauts left the International Space Station, the researchers found that evidence of their microbiome remained, and that four months later there was still a small number on the station. Curiously, the researchers also found that astronauts had reduced their saliva in space, returned to land and returned to normal, raising concerns about the potential impact of space flight on dental health.
“From microbial data alone, we can tell when new people will arrive and leave,” said David J.Smith, a scientist at NASA’s Ams Research Center and co-author of the study. We are used to using the calendar to record the passage of time, but in this study, the shift in the microbiome basically tells us the same story. “
