NASA's Jet Propulsion Laboratory Video and Audio Podcasts 12 Nov 2019, 08:00 UTC See how the odd orbits Neptune's inner moons Naiad and Thalassa enable them to avoid each other, as they race around the planet. Researchers call it a "dance of avoidance." An observer sitting on Thalassa would see Naiad in an orbit that varies wildly in a zig-zag pattern, passing by twice from above and then twice from below. This up, up, down, down pattern repeats every time Naiad gains four laps on Thalassa. This repeating pattern is called a resonance.
Naked Astronomy 10 Nov 2019, 05:21 UTC What would a house on Mars look like? Space Boffins Richard Hollingham and Sue Nelson tackle the tricky topic of Mars interior design and the challenges of moving to Mars. They're joined by the Head of Science for the UK Space Agency, Chris Lee, to also discuss a new mission to a comet - a comet that's not yet been discovered - and future international science missions. They also hear from Apollo 12 Flight Director, Gerry Griffin, recalling the dramatic launch of Apollo 12 and the switch - and puppet show - that saved the day. Like this podcast?

Talking Space Podcast 9 Nov 2019, 21:33 UTC In this special edition of Talking Space, we look back into the NASA audio archives and discover a hidden gem that might get lost in United States space flight history. On November 9, 1967, months after the United States lost three intrepid explorers duing a spacecraft test, The Apollo Progam arose like the mythical phoenix and launched the most powerfull launch vehicle the world had ever seen, the 364-foot tall Apollo Saturn V Rocket. Apollo 4 set sail from a brand new port, NASA’s Kennedy Space Center from a brand new launch complex, Launch Complex 39, and with the sucesssfull conclusion of the mission some 8 hours 36 minutes and 59 seconds later, restored confidence in the US Human Spaceflight Program. What is to follow is the post flight press conference for Apollo 4. In attendaence were space flight giants, with names like Robert Seamans, George Muller, Kurt Debus, George Low, and Werner von Braun. Its a time capsule of sorts, a moment that paved the way for the human exploration of the lunar surface for the first time, but also may give a hint of future events in NASA’s Artemis program.

Astronomy Cast 545: Weird Issues: Are comets asteroids or are asteroids comets? by Fraser Cain & Dr. Pamela Gay Things used to be so simple. Comets were snowballs from the outer Solar System, and asteroids were rocks from the inner Solar System. But now everything's all shades of grey. Astronomers have found asteroids that behave like comets and comets that behave like asteroids.Things used to be so simple.
