They will make the heavy-lift, fully reusable two-stage rocket called the Terran R. Their first rocket is the Terran 1 and it is scheduled for a first orbital flight at the end of 2021.
The new rocket, Terran R, will be just a bit smaller than the SpaceX Falcon 9. Terran R is 216 feet tall while the Falcon 9 is 230 feet tall. Terran R will have a 20000 pound max payload while Falcon 9 has 22500 pounds of max payload.
Terran R will be 3D printed and built in 60 days.
Relativity Space wants to have the following advantages:
Reliability: 100x Fewer Parts
Speed: 10x Faster Production Time
Flexibility: No Fixed Tooling and a Simple Supply Chain
Optimization: Compounding Iteration Quality and Time Improvements
100X LESS PARTS
RADICALLY SIMPLIFIED MANUFACTURING
By fusing 3D printing, artificial intelligence, and autonomous robotics, Relativity is printing its rockets' structure and engines, significantly reducing touch points and lead times, simplifying the supply chain, and increasing overall system reliability. Relativity can create its rockets, Terran 1 and Terran R, from raw material within 60 days.
