Episode notes
Importance of Geosynchronous Orbit
- Geosynchronous orbit is critical because satellites there appear fixed relative to Earth, supporting constant communications like DirectTV.
- Impulse Space's upgraded Mira spacecraft can travel from low Earth orbit to geosynchronous and even medium Earth orbit, enabling new mobility services.
High-Speed Space Mobility
- Mobility in space means fast repositioning, refueling, or supporting payloads, especially with chemical propulsion providing quicker maneuvering than electric.
- Impulse's spacecraft can thrust at about 50 pounds, enabling orbit changes in hours instead of months as with electric propulsion.
Tom Mueller's Propulsion Legacy
- Tom Mueller, employee number one at SpaceX, contributed to cracking reusable rocket engine technology.
- Now at Impulse Space, he applies his lifelong expertise in liquid propulsion to spacecraft propulsion development, continuing his legacy.
