As NASA is preparing to send astronauts back to the moon for the first time after more than 50 years, new research from the Sydney University of Technology finds that it finds that Lunar dust is less harmful to human lung cells From what scientists were previously afraid and significantly less toxic than common air pollution on Earth.

The study, published in the journal Life Sciences in Space Research, provides reassuring data on upcoming Artemis missions, which aim to establish a long -term human presence and a base on the moon. The researchers explored the laboratory the effects of the lunar dust simulars on human lung cells and compared the effects with those of the suspended particles collected from a busy road to Sydney.

The study focused on thin dust particles (≤2.5 micrometers), which bypass the natural defenses of the body and penetrate deep into the lower airways of the lungs. The study used two different types of pulmonary cells, representing the upper (bronchial) and lower (cellular) regions of the lung.

According to the results of the research, while lunar dust can act as a natural irritant, but did not cause severe cellular damage or inflammation observed by the urban dust of the Earth.

In Apollo missions, where crew members encountered respiratory problems, the main exhibition route occurred after activity outside the spaceship. “When the astronauts re -entered the landing unit, the fine dust attached to their space uniforms was hovered in the cabin and then inhaled, leading to respiratory problems, sneezing and eye irritation,” explains the lead researcher and researcher.

The findings of the study indicate that “while lunar dust can cause immediate irritation to the airways, it does not appear to be a risk for chronic, long -term diseases such as silicia, which is caused by materials such as silicon dust.”

While the findings reduce a crucial risk factor, NASA continues to take seriously the threat of dust exposure. Mikaela Smith, who recently visited NASA’s Johnson Space Center in Houston, describes the new mechanical solutions designed: “What they are planning now is that the uniforms are connected to the outside of the rover. The astronaut will go up and get down from the inside and the uniform will never come in, which prevents the dusty uniform from infecting the interior of the cabin. “
