Intro

Kerry Wisnosky believes the future of space power will be decided by maneuverability. As satellites remain largely static, Quantum Space is building the infrastructure to move, persist, and operate across orbits, from LEO to cislunar space.

The company is developing Ranger, a six-metric-ton, high-delta-V spacecraft designed to operate for up to 15 years, host and deploy payloads, maneuver freely between orbits, and function as a refueling node. By combining chemical and electric propulsion into a single multimode system, Quantum aims to deliver both high-impulse mobility and long-duration efficiency—turning spacecraft from disposable assets into persistent infrastructure.

Inside the episode:

• Why space remains a static domain and why maneuverability is the next decisive advantage
• How Ranger reframes satellites from disposable assets into long-lived infrastructure
• The strategic importance of fuel in orbit and why refueling changes mission economics
• Why multimode propulsion is the “holy grail” for mobility across orbits
• How life extension in GEO becomes the first commercial wedge
• What zone defense in space could mean for missile defense architectures
• Why Quantum was early to the market and why demand is finally catching up
