Aliens follow the spacecraft to Earth?

According to The Sun, Jupiter's moon Europa is home to a cold, harsh climate, but life can also exist.

Extraterrestrial organisms, which exist in the layers of rock that the spacecraft brings to Earth, can cause catastrophes that people don't expect.

According to The Sun, Jupiter's moon Europa is home to a cold, harsh climate, but life can also exist.

NASA plans to bring spacecraft and self-propelled robots to explore the miniature world, which may harbor this frozen ocean.

The rock and ice brought from the Moon Europa or Mars need to be permanently isolated if necessary, said Dr. John Rummel, a scientist from Seti Institute in California, USA.

Mr. Rummel made a statement in a discussion about space pollution, at the Scientific Development Conference (AAAS) in Boston, USA."If we bring the specimens back to Earth, we will have to isolate them until the test is complete, ensuring that no risk or survival will exist while we study the sample. object".

"Bacteria can still exist today, beneath the radiant surface of Mars, " Dr. Rummel said. Such potential pathogens can neutralize the human immune system.

Scientists believe that the Europa Moon has a large ocean beneath the ice. This may be where life exists at a simple level.

NASA plans to collect soil and ice samples from Jupiter's Moon Europa.

"Bacteria or aliens can easily survive on their journey back to Earth, if they are protected from the sun's ultraviolet rays," Dr. Rummel explained. "Like all bacteria in general, they are immune to the cold and dry environment."

"On the surface of Europa, the bacteria will die within a few hours to a few days. But if protected in a spaceship, they are still alive until the ship stops working."

The system to prevent the pollution of the passenger planet by Earth bacteria is also necessary, Mr. Rummel said. This also avoids being unable to verify alien life and bacteria originating from Earth.

Compared to the Moon Europa, Mars is less concerned by scientists because it has no ocean. Extreme climatic conditions mean that bacteria originating from the Earth will not be able to live long on Mars.
