NASA sends yeast into space to assess the impact of electromagnetic radiation on DNA

The American space agency NASA sends yeast into space to measure the impact of electromagnetic radiation on DNA. Instrumental in winemaking, baking and brewing since ancient times, sending the yeast variety “Saccharomyces cerevisiae” into space is part of an experiment to determine if humans can survive on lunar surfaces.

Since human beings have a lot more in common with yeast than you might think, scientists placed two strains of brewer’s yeast in canisters to fly on NASA’s next BioSentinel mission, which is tentatively scheduled for later this year.

According to Sergio Santa Maria, lead project scientist at BioSentinel, “Just imagine yourself sitting in free space, and you get hit from all directions all the time.”

As the reproduction of cosmic radiation in a laboratory is extremely difficult, but it is a significant danger for space travel, researchers must find a way to make longer space travel possible. without causing harm to the human body.

“The problem with solar protons is that there could be a lot of them, and they never stop,” according to Santa Maria.

“Saccharomyces cerevisiae”, which dates back to 3150 BC in an ancient Egyptian wine jar, repairs DNA damage and is a fantastic substitute for our cells according to NASA.

NASA’s Artemis 1 mission, the first big step in the space agency’s highly anticipated return to the Moon, will also host BioSentinel in a CubeSat.

The cereal box-sized satellite will detach from Artemis, which will take about three weeks, but BioSentinel will remain in space for much longer.

“Saccharomyces cerevisiae,” which will orbit the Sun, will be rehydrated and help the team get accurate deep-space exposure readings.
