Discovering life elsewhere: How can we be sure?
Is it life? NASA chief scientist Jim Green and Mary Voytek, leader of the agency’s astrobiology program, are two authors of a paper that calls for a system or scale that will allow scientists and others to evaluate the validity and importance of evidence that points to life elsewhere in the solar system or across the galaxy. Planetary Society communications strategy adviser Kate Howells shares our gift list for the space fan in your life, while Bruce Betts takes us across the night sky toward a new space trivia contest.

Spacecraft communications and navigation with Badri Younes
Badri Younes says that a spacecraft that can’t communicate or find its way is worthless. He leads SCaN, NASA’s Space Communications and Navigation program, which manages resources like the agency’s Deep Space Network. SCaN is also preparing for a future that relies on optical communication and possibly even quantum computing. Younes takes us on an audio tour of SCaN’s work that extends beyond our solar system.

Space Policy Edition: We're entering a new era of planetary defense (with Lindley Johnson)
The first in-space test of asteroid deflection technology, DART, launches this month. Lindley Johnson, NASA's planetary defense coordination officer, joins the show to talk about how this mission represents a new era for the agency's Planetary Defense program, and how it took nearly 25 years to convince policymakers, international partners, and even NASA that asteroid detection and deflection is an important use of taxpayer dollars. Casey and Mat also highlight the new Astrophysics decadal survey report and the federal ruling against Blue Origin in its effort to secure funding for its lunar lander.

Amazing Technology at the NASA Innovative Advanced Concepts Symposium
Planetary Radio host Mat Kaplan interviewed NIAC Fellows about their revolutionary projects as part of the 2021 virtual symposium. You’ll hear highlights including how we might grow structures on the Moon and Mars from fungi, and solar sails that will pass excruciatingly close to the Sun before they zoom out of our solar system. We’ll also check in with Society chief scientist Bruce Betts for another What’s Up.
