  • Go MECO!

    Huge fan of this one, always meaningful and with interesting insights. I like the fact that it does not have a defined frequency, but Anthony will comment most of the time within a week of any significant development. So when an episode is out, you know it is going to be worth it. And I never let an episode without listening for more than a few days. Keep up the good work Anthony!!

Talking Points

Recent interactions between the hosts and their guests.

T+309: EchoStar’s Spectrum Sale, Starlink’s Financials (with Caleb Henry, Director of Research at Quilty Space)
Q: What is the biggest criticism that you receive about the Starlink work that you're putting out and how do you defend it?
Caleb mentions that most criticisms revolve around revenue assumptions and subscriber numbers, and they have defensible reasons for their models based on their research.
T+309: EchoStar’s Spectrum Sale, Starlink’s Financials (with Caleb Henry, Director of Research at Quilty Space)
Q: How did you read the argument that EchoStar was not using the spectrum that was assigned to them?
Caleb explains that EchoStar's merger with DISH resulted in them becoming more of a mobile network operator, which has complicated their use of the spectrum effectively.
T+308: Chatting with Casey Handmer
Q: How do you see this couple, past couple months going, you know, from the outside?
Not great. Despite having not worked at NASA for almost four years, it seems clear that the organization is in decline.
T+296: Jim Bridenstine on Space Policy
Q: What are the challenges you're seeing with funding for the commercial space program?
Despite retaining programs, adequate funding didn't materialize as anticipated; it's vital for the US to secure access to microgravity and space exploration without relying solely on NASA's budget.
T+296: Jim Bridenstine on Space Policy
Q: What can you tell us about the Commercial Lunar Payload Services program?
The CLPS program aims to foster competition and innovation among private firms to successfully land payloads on the moon, making it accessible and cost-effective.
