Meet Leaders Of 3 Local Conservation Projects | Preserving ‘Space Junk’ Left On Mars

What makes three very different conservation projects so successful? These experts say it’s getting the community involved. And, archaeologists make a case for tracking and preserving artifacts left on Mars to chronicle humans’ first attempts at interplanetary exploration.Meet 3 Leaders Addressing Local Conservation ProblemsWhile 2024 saw a lot of governments and institutions falling short on climate goals, there were also smaller, localized efforts making a big difference for the environment.To understand more about the creative ways that people are protecting nature, Science Friday began a newsletter series called “Tiny Nature Triumphs.” It highlights small conservation projects that have helped scientists and communities alike—and inspired people to get involved in solutions in their own backyard.SciFri Digital Producer Emma Gometz sits down with leaders on three projects featured in “Tiny Nature Triumphs”—Claire Lane, an urban ecologist and leader on the Hamilton County Invasive Species Trade In Program; Jake Rose, co-founder of Chronolog; and Shaun Preston, yardmaster at Camp Small. They discuss how their programs address local conservation problems, and how to get involved.A New Argument For Preserving ‘Space Junk’ Left On MarsOver the past 60 years or so of space exploration, humans have left some things behind: bits of satellites, moon buggies, Mars rovers, even human excrement. It’s all part of the countless bits of human-made material that some people have dubbed “space junk.”But what if, many, many years from now, archeologists wanted to trace the chronology of space exploration by examining the items we left in our wake? A new paper in the journal Nature Astronomy argues just this, that artifacts should be considered heritage, rather than trash.Lead author Dr. Justin Holcomb, assistant research professor at the University of Kansas, joins Ira to discuss shifting our mindset on “space junk.”Transcripts for each segment will be available after the show airs on sciencefriday.com.
