SCRUB: Relativity Space launches First Terran 1 Rocket
NASASpaceflight・2 minutes read
The first launch attempt for relativity's Terran one rocket, the first methane-fueled rocket from the Florida Space Coast, is covered by NASA Space Flight with commentary from Chris Gephart, Adrian Biele, and Alejandro Romero. The rocket is methane-fueled and largely 3D-printed, aiming for a successful launch with a focus on reaching orbit and customer willingness to pay for payload placement.
Insights
- Terran one is a methane-fueled rocket, utilizing 3D printing for 90% of its mass, following a trend in the industry towards methane for Mars missions.
- The rocket's propulsion system, largely 3D printed using aluminum alloys, aims to achieve a total thrust of 920 kilonewtons with aeon1 engines, focusing on reaching crucial milestones like maxq.
- The decision not to separate payload fairings on the launch emphasizes testing the rocket's propulsion system rather than carrying a traditional payload, influenced by cost and customer willingness to pay.
- Propellant conditioning is crucial for rocket engines, requiring precise temperature control to ensure proper ignition and performance, with potential issues like combustion instability if not within the correct range.
- The 3D printing technology used in rocket production enables cost optimization, consistent manufacturing, and easy design adjustments without new tooling, potentially revolutionizing space exploration and production cadence.

What is the purpose of the Terran one rocket launch?
The Terran one rocket launch serves customers with booked payloads for multiple flights, focusing on commercial operations rather than being a technology demonstration.
How does propellant conditioning impact rocket launches?
Propellant conditioning is crucial for rocket engines to operate properly, requiring specific pressure and temperature ranges. If not within this range, engines may not ignite, affecting engine performance and potentially causing a failed launch.
What is the significance of 3D printing in rocket manufacturing?
3D printing technology in rocket manufacturing allows for cost optimization, consistent production, and easy adjustments to rocket design without the need for new tooling. Terran one is the first rocket with 85% 3D printed components, showcasing the efficiency of this technology.
What are the potential impacts of a failure during the Terran one flight?
In the event of a failure during the Terran one flight, there could be implications for Falcon 9's launch the following day, as past incidents have shown how one rocket's failure can affect another's launch schedule.
How does the flight termination system protect assets during rocket ascents?
The flight termination system plays a crucial role in protecting assets during rocket ascents by providing varying termination limits based on altitude and velocity. This system ensures safety by mitigating risks and controlling potential failures during the launch process.
