🚀 Super Heavy 19: Starship's HUGE Upgrade! 🔥
Science
🎧
SpaceX completed cryogenic proof testing of the upgraded Super Heavy booster at Starbase, Texas, a key step towards more ambitious missions. The multi-day campaign, utilizing liquid nitrogen, rigorously assessed the booster’s redesigned propellant systems and structural strength. Designated Booster 19, the Super Heavy underwent stress testing and returned to the factory early Monday. Technicians will soon install 33 Raptor engines, a change from the Starship V2 design, and integrate a hot-staging ring for reusability. Simultaneously, the first Starship vehicle, slated for a cryogenic proof test at the Massey’s Test Site, prepares for static fire testing. This 12th full-scale test flight, anticipated before the end of March, mirrors previous trajectories, aiming for a controlled reentry in the Indian Ocean. The culmination of these preparations represents a significant advancement in SpaceX’s efforts to develop a fully reusable launch system.
SUPER HEAVY BOOSTER CRYOGENIC PROOF TESTING COMPLETE
The upgraded Super Heavy booster, slated to launch SpaceX’s next Starship flight, has successfully completed cryogenic proof testing, marking a significant advancement in the development of the company’s mega-rocket. This multi-day campaign rigorously tested the booster’s redesigned propellant systems and its overall structural strength, addressing a key hurdle that led to the destruction of the previous booster. The testing phase involved repeated thermal and pressurization cycles, simulating the extreme conditions of a launch.
ROLLOUT TO MASSEY’S TEST SITE
Ground teams at Starbase, Texas, orchestrated the careful rollout of the 237-foot-tall (72.3-meter) stainless-steel Super Heavy booster last week. The booster was transported a few miles to Massey’s Test Site, preparing it for the intensive cryogenic proof testing. This strategic move facilitated the controlled execution of the testing protocols, centralizing the operations within a dedicated facility.
RIGOROUS CRYOGENIC TESTING PROTOCOLS
The test crew initiated the cryogenic proof testing by performing a pressure test on the rocket at ambient temperatures. Subsequently, they loaded super-cold liquid nitrogen into the rocket four times over a six-day period. This process meticulously replicated the conditions of a launch, subjecting the booster to repeated thermal and pressurization cycles. The liquid nitrogen served as a critical stand-in for the cryogenic methane and liquid oxygen that would ultimately fill the booster’s propellant tanks during the actual launch.
TRANSITION TO STARSHIP V3 – BLOCK 3
This proof test represents a pivotal step towards launching the first test flight of SpaceX’s upgraded Starship V3, also known as Block 3. The company’s previous efforts with Starship V2 yielded two successful flights, prompting a focused evolution towards the V3 design. The Super Heavy booster’s enhancements are designed to address previous shortcomings and improve overall reliability.
RAPTOR 3 ENGINE ADVANCEMENTS
The Raptor 3 engines, set to debut on Starship V3, incorporate key improvements focused on both increased thrust and enhanced reliability. Notably, the engines are lighter due to integrated plumbing and sensors within the engine’s main structure, eliminating the need for separate heat shields. This design change significantly streamlines the rocket’s architecture and reduces complexity.
REVISED AERODYNAMIC CONTROLS
The Super Heavy booster’s design has been refined with a reduction from four to three grid fins. These aerosurfaces play a crucial role in stabilizing the rocket during its descent and returning to Earth for recovery. This optimized configuration enhances controllability and contributes to a smoother, safer re-entry.
HOT-STAGING RING FOR REUSABILITY
A key innovation incorporated into the new Super Heavy booster is the hot-staging ring at the top. This integrated component enables the booster’s return to Earth for reuse, mirroring the functionality previously employed on earlier Starship flights. Following its test-firing, the ring will be jettisoned and expended, maximizing the system’s operational lifespan.
PREPARATION FOR LAUNCH PAD ROLLOUT
Once the Super Heavy booster receives its newly installed engines and grid fins, it will be rolled out to the launch pad at Starbase. SpaceX’s launch team will then proceed to fill the booster with methane and liquid oxygen, preparing it for a comprehensive test-firing of its 33 engines. This final pre-launch phase ensures optimal performance and readiness for the critical mission.
STARSHIP V3 UPPER STAGE CRYOGENIC TESTING
Concurrent with the Super Heavy booster’s preparations, SpaceX’s upgraded Starship vehicles—the upper stage that will fly on top of the Super Heavy booster—will travel to Massey’s Test Site for their own cryogenic proof test campaign. This campaign will also include a static fire test of the Starship’s six Raptor engines, further validating the integrated system.
TIMELINE FOR INITIAL STARSHIP V3 TEST FLIGHT
Assuming all tests proceed according to plan, SpaceX anticipates being in a position to launch the first Starship V3 test flight before the end of March. This 12th full-scale Starship/Super Heavy test flight will likely follow a similar trajectory to previous flights, with Starship arcing halfway around the world from South Texas to a controlled reentry and splashdown in the Indian Ocean.
CRITICAL PATH FOR ARTEMIS LUNAR PROGRAM
The successful launch and operation of Starship V3 are a critical path for NASA’s Artemis lunar program. A human-rated version of Starship is NASA’s primary option for a Moon lander, designed to ferry astronauts to and from the lunar surface on the Artemis III mission, the next Artemis flight following the Artemis II circumlunar mission which is awaiting liftoff in the coming weeks.
