Spacecraft need a navigation and communication infrastructure to carry out their missions. Learn how NASA does it and what’s in store for the future.
A fascinating, wide-ranging conversation with Brian Keating, director of the Simons Observatory that will search for our cosmic origins from a mountaintop in Chile’s Atacama region.
How astronomers at California’s Palomar Observatory revolutionized our understanding of the cosmos.
Host Mat Kaplan talked with the Arecibo Observatory director just hours before the giant radio telescope came crashing down.
Radio telescopes are delivering stunning images that, in some cases, current optical telescopes can’t equal. Witness the 20 beautiful protoplanetary disks imaged by the DSHARP team using the ALMA radio telescope in Chile.
Happy Astronomy Day, October 13, 2018! We salute humankind’s long history of stargazing by checking in on what will be our planet’s largest telescope. Patrick McCarthy is an astronomer and a leader of the Giant Magellan Telescope project. He returns with a report on the instrument’s status, followed by a fascinating tour of the GMT facility.
Elon Musk. Jeff Bezos. Richard Branson. These are the names we tend to associate with the current era of private space exploration. But what about John Quincy Adams, James Lick, or Charles Yerkes? Space economist and historian Dr. Alex MacDonald joins us to discuss his book,
Moon Express Founder and CEO Bob Richards shares an inspiring vision for a return to the Moon. It includes introduction of a sophisticated line of robotic spacecraft, the first of which may make a soft landing next year.
Canada has a new Space Advisory Board, and The Planetary Society’s Kate Howells is a member.
Congressman Adam Schiff’s California district includes the Jet Propulsion Laboratory. He is as enthusiastic a fan of the final frontier as you are likely to find under the capitol dome in Washington D.C.
The world’s most powerful solar telescope has just been renamed for the man responsible for its creation. We’ll meet astrophysicist and helioseismologist Phil Goode, and we’ll enjoy a tour of the Goode Solar Telescope.
The University of Texas at Austin’s observatory is high in the hills of west Texas. In this special episode, Mat Kaplan joins the tens of thousands who visit it each year. The occasion was the dedication of the vastly upgraded Hobby-Eberly Telescope, third largest on Earth.
Space historian John Logsdon remembers American hero John Glenn. Planetary Society CEO Bill Nye was a big fan of the Friendship 7 astronaut—less so the new Star Wars movie. Then we get an update on the Giant Magellan Telescope from Patrick McCarthy.

NASA has given the go-ahead for creation of the Wide-Field Infrared Survey Telescope. It might help reveal the nature of dark energy and point the way to life among the stars.
Emily Lakdawalla returns from the annual Division for Planetary Sciences meeting with big news from around the solar system. Then we talk with science journalist Traci Watson about the departure of the great Arecibo radio telescope’s Director and the funding challenge that could shut down the observatory.
Joe Liske, host of Hubblecast, is also the top scientist on the European Southern Observatory’s European Extremely Large Telescope (E-ELT), now under construction on a Chilean mountaintop. “Dr. J” tells us what this largest ever telescope will help us discover.
Principal Investigator and physicist Bruce Macintosh joins astronomer Franck Marchis to celebrate first light from the most powerful instrument for imaging exoplanets.
