Stage 2 testing is officially underway at NASA Stennis 🚀 The campaign kicked off with successful cryoproof, loading the stage with cryogenic fluids and pressurizing it beyond expected flight loads to validate its structural integrity, followed by COPV manifold proof testing to verify the high-pressure system that will pressurize propellants during flight. These tests also marked the activation of A2, bringing together the infrastructure, flight hardware, ground and vehicle software, and the integrated team of test, launch, and vehicle engineers. Next up: hot fire capable assembly work, then back to the stand ahead of stage hot fire testing. 🔥

🔥 Just another day at Stennis. Stage 2 successfully completed its first integrated hotfire! The A2 test stand was originally built in the 60s to support Saturn V Upper Stage testing (S-II). It was later reconfigured to be a single engine test stand for Shuttle Main Engine testing and development. The last Saturn V Stage test occurred October 30, 1970 on A2. It has been 55 years, 11 months, and 17 days since A2 supported stage testing capability. As of this morning, it is now 0 days.

September was a big month for test operations across our sites. 📍 NASA Stennis, MS Stage 2 completed its first wet dress rehearsal! The team put the stage through flight-like propellant loading, COPV fills, engine chill operations, and a simulated stage 1 ascent timeline, building toward its first integrated hot fire. 📍 Long Beach, CA All 13 Aeon R engines are installed on the thrust structure and are moving through integrated gimbal testing, validating their ability to pivot precisely to steer and stabilize the vehicle during flight.

The infrastructure required to launch a rocket of Terran R’s class is immense. At LC-16, we’re moving fast. ✓ Horizontal integration facility (HIF) is energized. This building will house Terran R's stages to be mated and prepared for launch ✓ 135 ton assembly room cranes completed their first proof load tests. These cranes will lift the vehicle for mate ✓ Transporter erector (TE) upper strongback was moved into the assembly room. This is part of the system that will transport Terran R to the pad and raise it vertical ✓ Permanent site power was activated with two dedicated 22-kilovolt feeds. This powers launch operations across the site

Hardware across the vehicle continues to advance through test. 📍 Long Beach, CA The first stage downcomer completed its full acceptance test campaign. This flight-critical component, which routes liquid oxygen from the tank to the engines, is now cleared for integration. 📍 NASA Stennis, MS Stage 2 is back in the hangar after completing cryoproof and COPV proof testing. Post-test inspections are underway ahead of Aeon V installation. A2 is being prepped for hot fire, with LOX farm flushes and heat exchanger activations. On the R stand, acceptance testing of flight 2 Aeon R engines is underway.
