Invasive science can help protect Earth and other planets from alien microbes. Part of the unfortunate Israeli moon probe was a group of tardigrades, or "blue bears." "These creatures are less than a millimeter long and can withstand cold, intense radiation by expelling nearly all of their moisture before entering NDE mode. Brecht tardigrades may have survived impact. They can regenerate by being reintroduced into water.
Tardigrades - sometimes called mossy pigs - sleep safely and may not be inactive on the moon. But, in general, scientists, governments, and space agencies around the world agree that bringing Earth to extraterrestrial life, or vice versa, isn't great. p>
A new article has been created in a growing body of literature. . In this case, he uses the growing field of invasive science - research into how non-native species on Earth spread to new places and change. The spread of zebra mussels throughout North America through their ability to compete with native species is a classic example. Finding or identifying microorganisms. Feeders (or anything big). "The concept of ecosystems is a very general one. It doesn't just apply to lakes or forests," Anthony Riccardi, a McGill University biologist and co-author of the article, told Ars. According to Riccardi, humanity is still far from finding life among the stars and thus finding alien ecosystems to introduce our Earth's microbes. But, as we move to other worlds, we must use the field of invasive science to protect Earth from alien microorganisms and alien planets. p> Advertising
It needs cooperation. “Given the question of potential biological contamination associated with spaceflight, my colleagues and I advocate the application of the science of conquest to security on a planetary scale.” Life, oh, finds a slow path
As humans spread far away, we may encounter life in celestial bodies Others, these types of life have so far been expected to be mostly microbial, although some experts suspect that Europa, one of Jupiter's moons, could host multicellular life. p>
If this seems unlikely, it should be. Keep in mind that our world is home to many lovers of extremism (living things in seemingly impossible areas that nest like nearby volcanoes). In addition, the bacteria survived outside the International Space Station for about a year. Space agencies like NASA do their best to send completely sterile things into space — but even their clean rooms aren't completely free of microbial life. Some experts have questioned whether we have actually introduced alien life (from a Martian perspective) to the Red Planet through the landing effort. p>
This type of pollution may pose a threat to the Earth. One mission can infect a planet with spores, spores can spread and adapt to the climate, and then the next mission can capture some advanced (but not entirely alien) life and bring it back to Earth.
If some of the environments we encounter in space are particularly small and islandy, they may be more vulnerable to invasion. This is often the case on wild islands. Biological invasions can be devastating. “We have dozens of studies that have taught us how vulnerable these systems are,” Ricciardi said. "If the species is misdiagnosed, it can cause ecological disturbances." p>
