DeepSummary
The podcast episode starts with a discussion between Jon Batchelor and Bob Zimmerman about the Lunar Reconnaissance Orbiter taking pictures of China's Chang'e 6 sample return mission on the far side of the moon. They talk about the geological context of the landing site and the potential nature of the lunar samples being collected.
The conversation then shifts to the Mars Perseverance rover, with Zimmerman describing the images captured by the rover, including its current location in the Neretva Vallis and the geological features like the "Bright Angel" area they are investigating. They also discuss the massive canyons and slopes present on Mars, which dwarf even the Grand Canyon.
Later, they discuss observations of gullies on Mars, which may have been formed by liquid water, glaciers, or climate cycles related to Mars' shifting tilt. Zimmerman also mentions the discovery of two supermassive black holes orbiting each other and the James Webb Space Telescope's infrared image of the Crab Nebula.

Top Episodes Quotes
- “These samples are going to probably be lava of some form. The question is when they were formed and how and so forth. But that's what they'll do, when they'll look at it when it comes back. But at least we know now exactly where Changi six landed.“ by Bob Zimmerman
- “Vallis Marineris is the biggest canyon on Mars. There are enclosed depressions near it that are as big and as deep or at least as deep. So I have posted what I call the insane mountain slopes of Mars deep canyons.“ by Bob Zimmerman
