In movies, asteroids careening towards Earth are confronted by determined humans with nuclear weapons to save the world! But a real NASA mission wants to change the course of an asteroid now (one not hurtling towards Earth). The Double Asteroid Redirection Test, or DART, launched in 2021 and on Monday, September 26, 2022, makes contact with the celestial object. In 2021, NPR science correspondent Nell Greenfieldboyce talked about what it takes to pull off this mission and how it could potentially protect the Earth in the future from killer space rocks, and that's what you'll hear today. And stay tuned - when NASA has the results of contact in a few weeks, Short Wave will bring Nell back to tell us all about it!Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

Dinosaurs ruled the earth for many millions of years, but only after a mass extinction took out most of their rivals. Just how that happened remains a mystery — sounds like a case for paleoclimatologist Celina Suarez! Suarez walks us through her scientific detective work, with a little help from her trusty sidekick, scientist-in-residence Regina G. Barber.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

In the final episode of Short Wave's Summer Road Trip series exploring the science happening in national parks and public lands, Aaron talks to National Park Service Director Charles Sams, who recently issued new policy guidance to strengthen the ways the park service collaborates with American Indian and Alaska Native Tribes, the Native Hawaiian Community, and other indigenous peoples. It's part of a push across the federal government to increase the level of tribal co-stewardship over public lands. Aaron talks with Sams, the first Tribal citizen to head the agency, about how he hopes this will change the way parks are managed, how the parks are already incorporating Traditional Ecological Knowledge, and what national parkland meant to him growing up as a member of the Cayuse and Walla Walla tribes on the Umatilla Indian Reservation in eastern Oregon.
