Location: Southwestern Yacht Club
2702 Qualtrough Street
San Diego, CA 92106 (Point Loma)
Guest Speaker: Andrea Decker, Adult Programs Manager, Fleet Science Center
Topic: Two Scientists Walk Into a Bar
Main Speakers: Eric Robinson, Strategic Outreach Manager, and Dr. John Hunter, CTO, Green Launch
Topic: Space Cannons – a Bridge to Low Earth Orbit and Beyond
Main topic abstract:
Green Launch is a technology created to revolutionize and expand our access to space, opening the solar system for exploration and unlimited resources.
The Problem: There is only one way to get your payload into space. Today’s rockets require years of planning, are very expensive, and produce tonnes of greenhouse gases to manufacture and launch. Rocket companies charge between $5,000-$15,000 per pound and years of planning to put anything into orbit. For many potential customers that is a deal breaker.
The Solution: Instead of using rockets, wouldn’t be incredible if there was an environmentally friendly, hypersonic space cannon to shoot satellites and supplies into orbit whenever you want?
Technology: The world’s projectile velocity record was set with a light gas gun. We utilize the fastest propellant known, hydrogen. Green Launch plans to use a hydrogen cannon to launch small satellites into space. Once the vehicle is in space, an onboard rocket fires, putting it into a designated orbit.
Phase 1 – Milestone Status – In less than 14 months, the Green Launch propulsion system has accelerated projectiles to hypersonic speeds horizontally.
Phase 2 – Ready for world record suborbital impulse launch into space.
Phase 3 – Deliver a payload into low earth orbit as proof of concept for a new economical route to low earth orbit.
