Looking for E.T.'s Laser Beam: An Optical SETI Update

A SpaceX Falcon 9 upper stage slammed into the moon on August 5 after spending over a year and a half drifting through the Earth-Moon system. Jared Head, museum facilitator at Columbia Memorial Space Center, producer at TMRO, and co-host of All Space Considered at Griffith Observatory, walks us through how a rocket launched in January 2025 ended up crashing into the lunar surface. Kate Howells, the Planetary Society's public education specialist, shares her experience witnessing Europe's first total solar eclipse in 27 years from a canyon in Spain on her honeymoon. Plus, Jack Kiraly, the Planetary Society's chief of advocacy, gives us an update on the campaign to save NASA science and the proposed changes to OMB's federal grant-making rules. We close with Bruce Betts, our chief scientist, who joins for What's Up, to discuss Point Nemo, the spacecraft graveyard in the South Pacific.

Jared Head, museum facilitator at Columbia Memorial Space Center and co-host of All Space Considered at Griffith Observatory, breaks down how a SpaceX Falcon 9 upper stage ended up crashing into the moon. Plus, Planetary Society staff reflect on the 2026 total solar eclipse in Spain and share an update on the fight to save NASA science.

The SpaceX Falcon 9 that crashed into the Moon

On August 12th, 2026, the Moon’s shadow will sweep across Iceland, Greenland, and Spain, bringing the first total solar eclipse visible from Europe since 1999. And because this eclipse happens near sunset, it promises to be one of the most visually stunning in living memory.

Astrophotographer Andrew McCarthy, founder of Cosmic Background Photography, joins the show to talk about his extraordinary 2024 eclipse image, his collaboration with the Artemis II crew to capture the Moon in unprecedented detail, and what he's planning for this unique low-horizon eclipse. Then, bioacoustics researcher David Mann, founder of Haikubox and Loggerhead Instruments, shares the results of the Eclipse Echoes study, which used a network of hundreds of AI-powered bird monitors to reveal how birds across North America responded to the 2024 eclipse. The answer is far more complicated than simply going quiet.

Total solar eclipse 2026: Astrophotography and birdsong

The White House's Office of Science and Technology Policy recently released "Science: A New Golden Age", a sweeping report that calls for a fundamental reimagining of how the United States funds and conducts science. Explicitly modeled on Vannevar Bush's landmark 1945 report "Science, the Endless Frontier," it challenges the traditional linear model of innovation, advocates for empowering individual scientists over institutions, proposes faster grants with less bureaucracy, and envisions a greater role for AI in the scientific process. But this ambitious vision arrives in a deeply contradictory context: the same administration has proposed slashing science agency budgets, cutting new NSF funding awards by over 50%, and imposing new bureaucratic controls on scientific grants.

Casey Dreier is joined by Zach Pirtle, deputy director of the Consortium for Science, Policy and Outcomes at Arizona State University, and the Planetary Society's Chief of Advocacy Jack Kiraly to unpack the report's proposals, tensions, and implications.
