Episode 219 In this episode of the Observers Notebook podcast, host Tim Robertson talks to Bob Lunsford about his process for observing and photographing the recent transits of Saturn’s moon Titan. Titan’s Orbit and Motion: • Orbital period around Saturn: ~15.945 Earth days • Average distance from Saturn: ~1.22 million km • Orbital inclination: ~0.3° relative to Saturn’s equator (small, so Titan’s path is nearly aligned with Saturn’s rings). • Apparent size: ~0.8 arcseconds (tiny, only detectable as a “point” in most telescopes). • Shadow transits are possible only when Saturn’s rings are edge-on (every ~15 years). • September 20, 2025 — Start around 5:09 AM UTC (≈10:09 PM PDT); ends ~7:34 AM UTC (~12:34 AM PDT); Titan may also be visible near its shadow. • After October 5–6, 2025, this spectacular phenomenon won’t happen again until 2038–2039.

Episode 209 In this episode of the Observers Notebook podcast, host Tim Robertson talks to Jack Daleo, Reporter covering the modern flying beat for FLYING Magazine, writing about topics like drones, unmanned aircraft systems, advanced air mobility and space travel. The National Transportation Safety Board (NTSB) and FAA oversee investigations of aircraft accidents in U.S. airspace. But what happens when a crash occurs hundreds of millions of miles away in outer space? Engineers with NASA’s Jet Propulsion Laboratory (JPL) in California and uncrewed aircraft systems (UAS) manufacturer Aerovironment, a prominent aerospace and defense contractor, are conducting what the space agency on Wednesday said is the first aircraft accident investigation on another world. Personnel are examining the final flight of NASA’s Ingenuity Mars helicopter, which hurtled into the Red Planet’s surface and was retired in January. We discuss Jack’s life and contact information.
