A new study has sent microbes to Earth’s stratosphere to test their resilience in conditions similar to those on Mars. The aim was to reveal its potential use and the threat it poses during space travel. The study found that the microbes were able to temporarily survive in conditions similar to the Martian surface.
studying It was conducted by NASA and the German Space Center scientists. Their work paves the way to understanding the threat microbes pose to space missions as well as the opportunities for resource independence away from Earth. Scientists say they have successfully tested a new method to expose bacteria and fungi to Martian-like conditions.
The test involved using a science balloon to transport their experimental equipment into Earth’s stratosphere. The researchers say that some microbes, especially spores of the black mold fungus, survived the flight even when exposed to very high concentrations of UV rays. Understanding microbes’ resilience in space travel is critical to the success of future space missions.
We point out that while humanity searches for extraterrestrial life, we have to make sure that nothing that has been discovered has not been transmitted with humanity from Earth. The researcher says knowing how microorganisms associated with humans can survive on Mars is very important as we look forward to long-term missions to the red planet. Microbes are also important for independent food production and material supply, which is an important thing away from Earth.
Scientists say that while many of Mars’ surface characteristics cannot be found or easily replicated on Earth, above the ozone layer in Earth’s middle stratosphere, the conditions are very similar to Mars. The team noted that not all microbes survived the flight, but the black mold Aspergillus niger can be resurrected once it returns home. This particular microbe was discovered on the International Space Station in the past.
