  • Sadly Political

    Wanted to like this show, but it has significant political overtones that distract. The recent episode about SpaceX permits is hardly journalism, but becomes weirdly emotional and strident against SpaceX and Elon Musk. Smart on their part to get more funding from the left side culture warriors, but sad for those looking for straight forward space and astronomy news.

  • Love the show but fix the audio levels

    I love science podcasts and I have been listening to all of Dr Pamala Gay’s fantastic work for years. From the very beginning of Astronomy Cast I’ve been hooked. Lately I’ve noticed that this show needs to up the audio levels on Pamela’s voice. Every time the commercials come on I wince from how loud it gets because I have to turn it up high to hear Pamela. 6 stars if you fix that problem. Otherwise I love the show.

  • Raise the speakers’ audio

    While I love the content, the audio levels are frustrating. (Hand-on-forehead).

    When mixing in the speakers’ audio, please raise speakers’ volume. If you compare it to other podcasts audio levels, speaker audio is very, very low. Audio level of intro music and other fill/transitions is ok. But audio of those speaking is barely audible.

    When listening to multiple podcasts and arriving at this one, after the intro in this podcast, I have to increase the volume by 1/3 to hear the speaker’s voice,... more

  • Blaring Commercial!!!

    Absolutely love this podcast but the speaking is so low and then commercials blast out my ear! I don’t want to drop it from my playlist but will be forced to if this isn’t corrected. I understand the need for a sponsor but please even out the volume.

Talking Points

Recent interactions between the hosts and their guests.

After Hours: International Moon Day 2026 with guest Jekan Thanga
Q: What do you see as the critical path for robotics and machine learning to support lunar exploration?
The critical path emphasizes seamless human-robot collaboration, emergency response automation, sensor networks for base management, smart bricks and construction, and robotics able to operate in extreme conditions like dust and radiation, all designed to reduce astronaut workload and increase safety.
After Hours: International Moon Day 2026 with guest Jekan Thanga
Q: What is your team hoping to get on the Moon now that mission cadences are increasing?
We are pursuing a diverse set of thrusts: technologies to enable reliable landers and rovers, robust shielding against the harsh lunar environment, and scalable base concepts like lava tubes, to enable safe, long-duration stays and to accelerate a broader space economy tied to science, manufacturing, and resource utilization.
After Hours: International Moon Day 2026 with guest Jekan Thanga
Q: Can you tell us a little bit about why Moon Day matters to you?
Moon Day matters because it highlights the Moon as a pivotal 'beachhead' for human exploration, science, and potentially a space-based economy, while also reminding us that the Moon still holds many mysteries about its geology, climate, and its influence on Earth ecosystems that we need to understand before establishing long-term habitation.
After Hours: Space Rocks Collected for Science with guest Dr Rhonda Stroud
Q: How do laboratory spectra compare with asteroid spectra, and why isn't there a perfect match?
Laboratory spectra come from meteorites in pristine form, while asteroid spectra reflect surface weathering and the sun's radiation, which can alter the surface so the two measurements don't align perfectly, though they still guide us toward likely matches and parent-body connections.
After Hours: Space Rocks Collected for Science with guest Dr Rhonda Stroud
Q: Could you walk us through the typical process from meteorite fall to laboratory analysis?
We identify a fall, collect the rock with care, cut it to reveal internal structures, and then use electron microprobes and optical or infrared microscopy to characterize mineralogy and isotopes, which helps us classify the meteorite and link it to a specific parent body.
