Alien Organisms on Earth Could Become a Reality Stranger Than Fiction, According to Scientists.

Scientists warn that if adequate biosecurity measures are not implemented, “alien species” on Earth may become a reality that is stranger than fiction.

A group of experts, including Dr. Phill Cassey, Head of the Department of Ecology and Evolutionary Biology at the University of Adelaide, have published a paper in the international journal BioSciences urging for increased acknowledgement of biosecurity hazards in the space industry.

“The entrance of private firms like has meant there are now more actors in space exploration than ever before,” stated Associate Professor Cassey.

“We must take immediate measures to mitigate such hazards.”

Space biosecurity is concerned with the transmission of organisms from Earth to space (forward contamination) as well as the reverse (reverse contamination) (backward contamination). While the risk of alien species surviving the journey is now minimal, it is not impossible, according to the scientists.

“Risks with a low chance of occurrence but the potential for dramatic repercussions are at the heart of biosecurity management,” Dr. Cassey stated. Because things go horribly wrong when they go wrong.” The findings show how people have spread organisms to the farthest reaches of the earth and water, as well as into space.

The authors argue that the burgeoning area of ‘invasion science,’ which studies the causes and effects of bringing organisms into new settings, could provide useful insights into the risks of invading species from space flight. Insular systems, such as islands, lakes, and remote environments, are particularly sensitive to invasion concerns.

Protocols for early identification, hazard assessment, fast response, and containment techniques presently employed in response to invasive species threats could also be applied.

“It is significantly cheaper to prevent biological contamination on Earth by establishing guidelines than it is on, for example,” Dr. Cassey added.

Dr. Cassey and co-author Dr. Andrew Woolnough of the University of Melbourne and the University of Adelaide argue that Australia is well-positioned to provide expertise in this area because it has some of the greatest biosecurity in the world.

“This is a tremendous chance for us to contribute to international policy and develop biosecurity mitigation techniques that the growing commercial space industry can adopt.” Dr. Woolnough stated, “This is an untapped economic development opportunity.”

Despite the importance of invasion biology to space biosecurity, the authors claim that invasion biologists have not been included in the Committee on Space Research Planetary Protection strategy. In this issue of Brinkwire, we have a… Brinkwire News Roundup.
