Amateur Astronomers Work To Save Earth From Asteroids!

Seven astronomers have been selected to receive Shoemaker NEO (Near Earth Object) grants from the Planetary Society. They and their observatories span the planet. We’ll meet an American and an Australian. Society Chief Scientist Bruce Betts provides an overview of the grant program and later returns

Episode Summary

Executive Summary: This Planetary Radio episode covers Canadian space policy disappointment over a missing federal space strategy, then highlights the Planetary Society’s Shoemaker Near-Earth Object grants through conversations with two amateur astronomers using upgraded telescopes and cameras to track asteroid light curves and binaries. The show closes with Bruce Betts on LightSail 2 integration and his usual skywatching and contest segment.

Main Topics: Canadian space policy and budget disappointment: Kate Howell explains that Canada’s new federal budget did not include the anticipated national space strategy, disappointing the space community despite optimism around science funding and regulatory improvements. Planetary Society advocacy in Canada: Howell describes accompanying Bill Nye to Ottawa to meet Prime Minister Justin Trudeau and steer discussion toward the importance of space, planetary science, and strategic vision for Canada’s space future. Shoemaker Near-Earth Object Grants overview: Bruce Betts summarizes the long-running grant program that equips advanced amateur astronomers with better telescopes and instrumentation so they can contribute meaningful asteroid observations to planetary defense. Don Prey’s asteroid observations and equipment upgrades: Don Prey discusses how a new mount and camera will improve his remote observatory work in Massachusetts, especially his studies of asteroid light curves and binary asteroids. Julian Owey’s southern hemisphere asteroid work: Julian Owey explains how his Australian observatories, including the new JBL Observatory and the Blue Mountain Observatory, help fill a scarcity of southern hemisphere near-Earth asteroid observation capacity. LightSail 2 and spacecraft integration: Bruce Betts gives an update from Cal Poly San Luis Obispo about integrating LightSail 2 into the P-Pod and preparing it for transfer to Albuquerque for further assembly. Weekly skywatching, history, and contest segment: The episode ends with Bruce’s viewing advice, a space history note on Messenger, a constellation fact about Hydra, the Canopus contest results, and a new question about the smallest modern constellation.

Key Arguments: Canada needs not just science investment but a new space strategy and long-term vision; the budget’s omission of space was therefore a major setback. Planetary science offers high return on investment for countries with smaller space budgets because it yields significant scientific value relative to cost. Shoemaker grants enable advanced amateur astronomers to become serious contributors to planetary defense by improving precision, automation, and data quality. Tracking asteroid light curves helps determine rotation periods and can reveal binary systems, which would matter greatly in any future deflection effort. A strong southern hemisphere observing network is important because fewer facilities are available there to monitor near-Earth asteroids. Automation, improved CCD cameras, and better mounts have transformed amateur astronomy into a highly capable research activity. LightSail 2 is progressing through spacecraft integration steps toward its eventual launch path, showing continued momentum for solar sailing technology.

Data Points: Shoemaker NEO grants in latest round: 7 - Bruce Betts says the program awarded seven grants in the current round. Continents hosting grant-funded observatories: 4 - Bruce notes the awardees’ observatories are spread across four continents. Continents covered by the program overall: All except Antarctica - Bruce says the program has funded observatories on every continent except Antarctica. Don Prey grant amount: $11,000 - Prey says his Sugarloaf Observatory received $11,000 for a new mount and camera-related upgrades. Don Prey telescope size: 20-inch reflectors - Prey operates two 20-inch telescopes from small observatories behind his house. Julian Owey planned telescope size: 20-inch telescope - Owey says the grant will allow him to purchase a 20-inch telescope for dimmer asteroid targets. Blue Mountain Observatory telescope size: 24-inch scope - Owey mentions a 24-inch telescope already operating at Blue Mountain Observatory. Don Prey observing nights per month: 7 to 8 nights - Prey estimates how often weather and moon conditions allow him to observe. Year Messenger became Mercury orbiter: 2011 - Bruce mentions the Messenger mission as the first and only Mercury orbiter so far. Hydra sky coverage: 3.16% of the total sky - Bruce cites Hydra as the largest of the 88 modern constellations. Contest answer: Canopus - Bruce confirms the second brightest star in the night sky from Earth’s perspective is Canopus. Contest winner location: Flagstaff, Arizona - Megan Stanley is identified as the first-time winner. LightSail 2 integration site: Cal Poly San Luis Obispo clean room - Bruce says the spacecraft was integrated into the P-Pod there.

Pivotal Quotes: "we're really looking for not only new funding, but really a new vision and strategic direction." — Kate Howell: On what Canadian space advocates want beyond the federal budget "The Gene Shoemaker Near-Earth Object Grants are grants that the Planetary Society has been giving out for more than 20 years." — Bruce Betts: Explaining the purpose and longevity of the Shoemaker NEO program "Save the planet while having fun at the same time." — Julian Owey: Describing the motivation behind asteroid photometry and near-Earth object work

Implications: The episode underscores how policy, funding, and grassroots expertise intersect in space science: Canada needs strategy, and amateur astronomers can materially support planetary defense. It also shows steady progress on LightSail 2 and the growing sophistication of citizen science.
