My guest this week: Mike Grace, Founder and CEO of Longshot Space. Longshot is developing a kinetic launch system, using a multi-injection gas-powered cannon to send payloads to orbit at significantly reduced costs. Mike explains the engineering behind the technology, its economic advantages, and the challenges of creating a system capable of high-velocity launches.

📍 About the Guest:

Mike Grace, Founder and CEO of LongShot Space. After serving in the Army Mike studied economics and found himself, inexplicably, doing an astrobiology internship at NASA Ames. That ended up turning into a job, a wife, a master’s degree in genetics, and several stints at aerospace and biotech startups.

Mike enjoys board games and wearing inflatable t-rex costumes to events where they are not really appropriate.
