BREAKING: Inside Impulse Space with Tom Mueller (@lrocket) (SpaceX's 1st Employee)
FULL TOUR
The famous engineer behind the Merlin engine, now Founder, CEO & CTO of Impulse Space (@GoToImpulse)
ICYMI: Merlin still powers Falcon 9 today, the most reliable rocket engine ever flown & the highest thrust-to-weight ever developed. It's the workhorse behind nearly every SpaceX mission: Starlink launches, Dragon crew & cargo flights to the ISS, & booster landings
Tom walks us through the factory floor, from the avionics clean room to a live rocket engine firing in the vacuum chamber
Impulse is building the in-space mobility layer: the vehicles & engines that move spacecraft after launch, from LEO to GEO, the Moon, infinity & beyond
We cover:
→ Mira: precision maneuvering spacecraft & its saiph thrusters (8 thrusters, ~50 lbs thrust, 5-yr orbit life)
→ Helios: long haul same-day delivery vehicle (12 tons of LOX/methane, LEO to GEO)
→ Deneb Engine: 15,000 lbs thrust engine that powers Helios, ox-rich staged combustion, carbon skirt running over 3,000°F
→ Why 3D printing is "almost a cheat code" for rocket engines
→ In-house composite tanks, Novaloy, & copper liners machined from 700 lbs down to 25
→ 3 spacecraft in orbit + a 1,200-meter rendezvous
→ Starlink, iterating Merlin & Raptor, & working with @elonmusk
→ Nuclear propulsion, the Moon, & why compute needs to move to space
