T-Minus: Space-Cyber Briefing Orbital debris remediation as a stepping stone toward asteroid mining.
May 3, 2026
Joe Sercel, CEO of TransAstra and space engineer with JPL/Caltech roots, discusses his CaptureBag demo aboard the ISS and its role in orbital debris cleanup. He explores using the same tech to rendezvous with and secure small near‑Earth asteroids. Conversation covers why asteroids are prime sources of water and materials and how captured resources could enable in‑space manufacturing and propulsion.

Episode notes
CaptureBag Bridges Debris Cleanup And Asteroid Mining
- TransAstra developed CaptureBag for asteroid mining and found it also fits orbital debris cleanup because capture, detect, move, process overlap.
- Joe Sercel explains the same tech scaled smaller cleans debris and scaled larger secures small asteroids for industry.
Rapid Prototype Went From Sketch To ISS In Six Months
- TransAstra moved from sketches to flown hardware in six months and integrated with a Northrop Grumman resupply vehicle to fly on a Falcon 9 to ISS.
- The ISS demo proved vacuum and microgravity performance and showed system robustness despite faults.
Small Asteroids Are Easier And Richer Than You Think
- Small near‑Earth asteroids (5–10 m) are ~500× more numerous and often easier to access than the Moon because their return delta‑v is much lower.
- One in five may contain ~10% water; others hold metals and silicon useful for in-space industry.
