Definition
A key SpaceX propulsion engineer who succeeded Jeremy Hollman as the lead for the Merlin rocket engine development and oversaw the 9-engine cluster for the Falcon 9.
Why It Matters
Reliable launch operations require the integration of thousands of people and millions of parts. Miller’s role in mission management ensures that the “human system” is as precise as the “mechanical system,” turning complex aerospace projects into successful deliveries.
Core Concepts
- Background: Grew up in Indiana; Purdue graduate. Inspired by the Apollo 9 capsule and F-1 engine at the Michigan Space and Science Center.
- NASA Co-op: Realized he didn’t want a civil service career after seeing projects take 20 years without flying.
- SpaceX vs. Blue Origin: Chose SpaceX over Blue Origin in 2005 because of the “beehive of activity” and hands-on work in El Segundo.
- Merlin 1C Development: Led the transition to regenerative cooling and the “punting the pintle” troubleshooting.
- Responsibility: Managed the 178-second full-duration test of the Falcon 9 first stage on November 22, 2008.
