AST SpaceMobile Podcast Anpanman - Block 2 Unfolded
8 snips
Feb 11, 2026 A deep dive into the successful unfolding of a massive 2,400 sq ft phased array and why that milestone quiets long-standing skeptics. The episode explains a novel self-encapsulated "tuna can" satellite design that avoids debris and simplifies deployment. It covers a bold reverse-testing strategy that sped development, the engineering culture behind careful builds, and why patience matters during detumbling and calibration.

Episode notes
Achieved Rare Large-Scale Deployment
- Unfolding a 2,400 sq ft phased array places AST SpaceMobile in an elite class previously limited to NASA and intelligence agencies.
- Successfully doing this multiple times proves the company solved a uniquely hard engineering challenge.
Reverse Testing With A Phone In Space
- AST SpaceMobile tested in reverse by launching a phone in a CubeSat while iterating the phased array on the ground.
- That approach saved time and capital and allowed rapid iteration before flying full arrays.
Tuna-Can Design Cuts Debris And Complexity
- Block 2 ('tuna can') is a self-encapsulated design that removes launch vehicle adapter debris and simplifies unfolding.
- Fusing more microns into larger rigid panels reduces hinge count and potential failure points despite larger deployment stresses.
