Listen as the Double Asteroid Redirection Test spacecraft closes in on asteroid Dimorphos, followed by a triumphant conversation with DART Coordination Lead Nancy Chabot, and a visit with space image processor Judy Schmidt.
We Earthlings are making progress toward defending our planet from near-Earth objects, which is reason enough for the annual Asteroid Day celebration.
Suit up for an up-close encounter with the Psyche spacecraft that will soon launch toward the asteroid belt.
The Planetary Society’s new Science and Technology Empowered by the Public (STEP) grant program will let citizens join the search for ET and enable astronomers to discover the nature of hundreds of near-Earth asteroids.
Meet three of the just-announced recipients of Planetary Society Gene Shoemaker NEO grants. They search the skies for asteroids and comets that could threaten our planet.
The DART mission begins its journey that will end when it smashes into an asteroid, demonstrating how we might save Earth from a devastating impact.
The head of the United Arab Emirates space agency announces a new mission to explore seven asteroids.
The ion engine-powered Dawn spacecraft will orbit Ceres for many years. Could it have touched down on the surface of the dwarf planet?
Six planetary defense leaders report on progress toward protecting Earth from near-Earth objects.
Hayabusa2 project manager Yuichi Tsuda shares the exciting success of Japan’s sample return mission ti asteroid Ryugu.
Joel Sercel believes we are entering an era in which asteroid mining and other commercial development of space are imminent, but he’s concerned about how we will avoid the mistakes of past eras of human expansion.
The leader of the OSIRIS REx asteroid sample return mission shares more details of last week’s encounter in an exclusive interview, while we also learn about the proposed mission to look for life on Saturn’s moon Enceladus.
Former Dawn mission director Marc Rayman of JPL reveals the secrets of the bright spots on dwarf planet Ceres, and we celebrate 10 years as Planetary Society CEO with Bill Nye.
OSIRIS-REx mission leader Dante Lauretta takes us to mysterious asteroid Bennu where a first sample collection site has been selected.
Planetary Scientist Jim Bell and space entrepreneur Lon Levin are founders of a new non-profit that aims to make robotic space exploration much more achievable by institutions around the world.
We talk with two of our 2019 Shoemaker NEO Grant winners, who received funding to help find, track, and characterize potentially hazardous asteroids.
As the 2010s come to a close, Marcia Smith, the founder of Space Policy Online, rejoins the show to explore the most significant and impactful space policy decisions of the 2010s.
How can a simple report—just words on a page—lead to creation of a spacecraft? We explore how a 2019 report on the need for a dedicated, space-based telescope to find threatening near-Earth asteroids motivated NASA to pursue that very mission.
Leaders of the global effort to avoid a catastrophic Near Earth Object impact gathered at the 2019 Planetary Defense Conference. On the evening of May 1st, The Planetary Society partnered in an exciting PDC public event at the University of Maryland College Park. Presentations by Society CEO Bill Nye and NASA Chief Scientist Jim Green were followed by Planetary Radio Live.
A rare alignment of planets and other objects will enable the solar-powered Lucy spacecraft to examine seven asteroids, six of which are among the thousands of Trojan asteroids that orbit ahead of and behind Jupiter. The mission team, include Hal Levison, Cathy Olkin and Mike Sekerak, hope to unlock secrets of our solar system’s origin through these ancient artifacts.
