Science Friday

Big cats used to roam the entire United States. You might know them as mountain lions, pumas, cougars, or catamounts. Though they go by many names, they're actually all the same species. 

Their current population is mostly confined to the West, and part of Florida, though in recent years they’ve been spotted in other areas east of the Mississippi River. Most cougars were gone from the Northeast by the 1800s, with the last verified accounts in the 1930s. 

Mountain lion ecologist Mark Elbroch hopes to reintroduce these big cats back into their previous habitats in New England. But, should we? What are the benefits and drawbacks of reintroducing the apex predator into an ecosystem it's been away from for so long? 

Guest:

Dr. Mark Elbroch is the director of the puma program at Panthera, a big cat conservation organization.

When Blue Origin’s New Glenn spacecraft exploded in an enormous fireball during a ground test a couple weeks ago, it sent shockwaves not only through the air, but through NASA’s timeline for the upcoming Artemis missions.

It also came at an especially bad time for Jeff Bezos’ rocket company—just days after it was awarded a slew of NASA contracts to deliver equipment to the moon. Blue Origin had also been expected to play a major role in the upcoming Artemis III and IV missions, but that’s now more up in the air depending on how soon the company can rebuild its only launchpad.

And with NASA’s Artemis III crew announcement this week, Guest Host Jane Lindholm sits down with space reporters Ken Chang and Brendan Byrne to break it all down and what’s next for the space program.

Guests:

Ken Chang is a science reporter at the New York Times, where he covers NASA and the solar system.

Brendan Byrne is a space reporter for Central Florida Public Media and host of the podcast “Are We There Yet.”
