The moon is perhaps more hospitable to life than we shook, which increases the risk of future moon tasks that pollute the lifeless lunar surface.
Rummustter must follow police policy on “planetary protection” to avoid polluting other bodies of the solar system with microbes from the ground – which may mislead us into believing that these bodies have their life forms.
Many of the protections we have on Earth, such as our atmosphere and magnetic field, you are on the moon. As a result, its surface is exhibited to the high energy party from other space spaces, extreme temperatures and deadly ultraviolet light from the sun, making it a surcrement for organizations to survive in.
Because of this, most astronomers consider the moon surface essentially sterile. The committee on space research places it in the second lowest category of planetary protection with Venus and comets for bodies that have “only a distant luck, such as spacecraft burning pollution of cold compromise studies”.
But new research from Stefano Bertone at NASA Goddard Space Flight Center and his colleagues suggest that life may survive for several days, or potentially more than a week, in some regions around the moon’s poles, which is, as NASA’s future Artemis mission plans to visit. This means that there are risk tasks that will pollute these areas, leading to false positive in studies searching for life.
“We will return to the moon. We will lead tracks. We need more work to understand how kind of tracks we will leave and how to minimize them,” Bertone told the Europplan Science Congress (EPSC) in Helsinki, Finland on September 12.
Bertone and his team looked at five ordinary organizations that are naturally resistant to extreme environments, included black mild (Aspergillus Niger) and the bacteria Staphylococcus aureus and Bacillus subtilis, And tested how much ultraviolet light they could withstand in the laboratory. Then they compiled the data for UV levels, solar exhibitions and temperature fluctuations on the moon’s surface and use this to produce a map showing where the five organizations that survive for at least one day.
All organizations could survive in areas that are well enlightened, outside the permanently shady regions where the sun and UV light cannot reach, Bertone said, and these well-informed areas are potential targets for moon exploration. Black mold was the hardest and survived in large regions for up to seven days.
“It is a very important study and it is clear that if there is a danger [of contamination]Then certain actions must be taken, but it must also be understood that it [such actions] Want to have financial consequences, “says Stas Barabash at the Swedish Institute of Space Physics. For example, space agencies may decide that equipment has been sterified more strictly and this will affect the cost of missions, he says.
