It is understood that NASA is planning to bring rocks from Mars to earth. The space agency has sought public opinion on its plan to retrieve samples collected by perseverance Although many people are excited about this, some scientists worry that alien bacteria will also take the opportunity to come to earth
Scientists warn that Martian samples may contain alien bacteria
Right now, NASA is holding a public meeting this week to solicit feedback on its sample recovery plan. Currently, the space agency plans to land a spacecraft carrying a Mars sample at a U.S. Air Force Base in the early 2030's. This is still a long process, but some scientists warn that NASA needs to ensure that the earth is protected from any alien germs that may be brought back.
"I think there's a very low probability of any life on the surface of Mars. But there's one possibility," said geologist Peter Doran from Louisiana State University
NASA's current plan will see a container containing samples launched into orbit from the surface of Mars. From there, another container will collect the sample container from the track. From there, samples will be sent to earth to study them. Similarly, this is an immortal action, and it is also an action for which we have worked for a long time. But what happens if these samples do have alien germs?
Unable to adapt to the survival of the earth
If you've seen a lot of science fiction movies, you may belong to the worry camp. Although it seems impossible for us to worry that alien germs will affect us on earth, there is always such a possibility. However, Jim Bell, a planetary scientist at Arizona State University, believes that no life on Mars is suitable for living on earth.
"We're talking about a completely different ecosystem, a completely different potential biosphere. Of course, we don't know if there is or ever was a biosphere on Mars," he said.
Therefore, the chances of any alien germs surviving on Mars samples are very low. However, NASA will not ignore this danger. The space agency is planning to take a conservative approach to bringing samples to earth. And NASA will disinfect anything that has come into direct contact with Mars( ?site_id=242986&euid=&t=https%3A%2F%2Flist.jd.com%2Flist.html%3Fcat%3D737%2C13297%2C1301 ) And control.
Of course, there may still be variables about how NASA will implement this plan. And in the coming months, we may see more information about how NASA plans to deal with any alien germs that may be found. If we earthlings really want to let Mars breathe and find a way for humans to live on Mars, we will need to carry out more in-depth research on these samples.
