Episode T+213: Amazon’s Project Kuiper Launch Contract Blockbuster

Main Engine Cut Off

Amazon is purchasing up to 83 launches from Arianespace, Blue Origin and United Launch Alliance—in addition to the 9 Atlas V launches they bought last year—to deploy their Project Kuiper constellation. This is a huge deal that changes the game for heavy lift launch providers, and has major implications for the small launch providers in the industry.

Episode 55 - I’ve Slept on a Torpedo


Tory Bruno, CEO of United Launch Alliance, joins Jake and Anthony to talk about how he got into space, his background in engineering, the shift from engineering to management, and the future of ULA and the rest of the space industry.

Episode T+211: Political and Industrial Fallout of the War

Main Engine Cut Off

A follow-up on my last show with Debra Werner about the war in Ukraine and all the fallout from it, both political and industrial.

Episode 52 - We Have All of Them


Anthony is joined by Tim Dodd, the Everyday Astronaut, and Roland Miller, a photographer who has spent years documenting space hardware of all varieties.

Episode 51 - Hubbles In Reverse
