A recycling truck in space could solve a growing problem: trash in Earth’s orbit-- junk that threatens everything from GPS satellites to the space station. Last week the U.S. Space Force announced a plan to promote manufacturing and recycling in space. That’s an opportunity for Denver-based CisLunar Industries, which is working on space recycling. CEO Gary Calnan explains the technology and Colorado School of Mines professor Angel Abbud-Madrid weighs in on the potential implications.

"Tree Line” is familiar to people in Colorado. That's the altitude that trees won't grow above in the mountains. There are also global tree lines. As you near the North and South poles, trees yield to extreme conditions. We now know precisely where that is in the Southern hemisphere because scientists have identified the world's southernmost tree. Brian Buma trekked to that tree. He’s an associate professor of integrative biology at the University of Colorado Denver.

A trio of Colorado mountain climbers plan to make the first all-Black expedition to Mountain Everest next spring. They’re led by Phil Henderson of Cortez.

Lucy's on board an Atlas V rocket at Cape Canaveral in Florida and is expected to launch on Saturday. It will travel eight billion miles over the next 12 years.
