SpaceX Did Something Never Done in 2.5 years on Starship B19! Ready for Firing on Pad NOW…

SpaceX has just conducted an impressive cryogenic test for its V3 booster, marking a milestone we have not seen in years. This is the moment everyone has been waiting for. It is time to fire. Next, SpaceX has received approval to expand Starbase, opening the door to even more ambitious development ahead. And there is still more to come. Meanwhile, SpaceX's plan for an in-space data center supported by one million satellites has been approved, signaling a bold new direction for orbital infrastructure. Let's explore all of this on today's episode of Great SpaceX. Following the movement of B19 on January 31st, SpaceX conducted a series of smaller tests, beginning with a pressure test. After the vehicle stabilized, signs suggested that fuel loading had begun. However, the initial loading appeared to involve only the liquid oxygen tank, as indicated by frost forming exclusively on that section of the booster. Based on this, I anticipated that another, more comprehensive test would follow. That test not only took place, but it exceeded expectations. The test occurred on the afternoon of the 4th of February, and this time, the entire booster was covered in white frost. This condition, commonly referred to as a full frosty, is something typically seen only on launch day. During this test, both fuel tanks were fully loaded, resulting in the booster being completely encased in frost. This visual confirmation clearly demonstrated that a full cryogenic load had been achieved. Notably, this represents the largest cryogenic test conducted on a Super Heavy booster since Booster 9, which flew on Flight 2. Between B9 and B19, SpaceX typically tested only one tank at a time, either fully loaded or partially loaded, or tested both tanks simultaneously without fully loading them. The reason for this lies in testing infrastructure. B9 was cryogenically tested at the original OLM at Pad 1, which was equipped with a complete refueling system. Beginning with B10 in July of 2023, cryogenic testing was relocated to the Massey test site. At that time, Massey lacked sufficient space and infrastructure to support full loading of both booster tanks. As we know, the Massey test site has undergone continuous upgrades. It also suffered damage last year, and alongside the transition from V2 to V3 hardware, Massey has received extensive improvements from the latter half of 2025 through the present. Now, after more than two years of development, Massey is robust enough to support full cryogenic testing of the Super Heavy booster. This demonstrates that the site now possesses capabilities comparable to those of the launch pad. As a result, Starship testing can be conducted more efficiently while fully validating the vehicle's launch day condition. To date, the system has been pushed to its limits with no reported incidents, indicating that the B19 test was successful. Most importantly, it has achieved what its predecessor, B18, was unable to accomplish. The outcome highlights the effectiveness of SpaceX's rapid improvement efforts. What do you think of B19's performance? If you were impressed, let me know with a WOW in the comment section down below. With this milestone completed, the first major test phase for B19 is likely finished. The vehicle is expected to be transported to the production site soon for inspections and to receive the highly anticipated Raptor 3 engines. What comes next? Well, it's time to fire. B19 will be moved to Launch Pad 2 for a static fire test. This event will mark the debut of Booster V3, the Raptor 3 engine, and Launch Pad 2 working together. Raptor 3, which has been discussed for some time, features a simpler design, higher thrust, and significant upgrades across multiple performance metrics. With 33 engines operating simultaneously, Booster V3 is expected to produce more than 9,000 tons of thrust. Confronting this immense power will be Launch Pad 2, which incorporates a major upgrade over Pad 1. Instead of a hexagonal inverted showerhead design, Pad 2 uses a dual flame trench system. This approach allows for improved heat and pressure distribution, better protecting both the vehicle and the launch infrastructure while supporting long-term reusability. The OLM has been upgraded to enable more effective testing and launch operations. Since construction began, testing at Pad 2 has primarily involved the chopsticks system or water deluge testing within the flame trench. More recently, SpaceX has conducted tests of the Fire X and Detonation Suppression System. What we haven't seen yet is a full-engine firing test. This type of test is critical for validating the upgrades SpaceX has implemented at the Launch Pad. It'll allow engineers to evaluate performance, identify weaknesses, and make necessary refinements in the remaining time before flight. Data gathered will also inform improvements at other pads under construction, including Pad 1 and Launch Complex 39A. In terms of timeline, B-19 is expected to arrive at the production site this week. Inspections and engine installation will likely take about a week, which suggests that the next major test could occur around the middle of the month. Alongside B-19's movement, S-39 is also expected to roll out soon. Given the performance demonstrated by B-19, S-39 may undergo the most intense cryogenic testing yet for an upper stage. Of course, beyond impressive performance, reliability remains critical. This is especially important as SpaceX targets a flight in early March, as recently stated by Elon Musk. If B-19 continues to perform as it has so far, it may provide the solid foundation needed for all subsequent steps to proceed smoothly. Not only with Flight 12, SpaceX has also made significant progress at Starbase itself. Over the years, Starbase has expanded steadily in both scale and capability, with the launch site consistently emerging as the center of growth. In its earliest configuration, when only Pad 1 existed, the launch site occupied a relatively compact horizontal P-shaped footprint. That layout changed as SpaceX expanded the former suborbital area to accommodate Pad 2, transforming the site into a broader horizontal B-shaped complex. Now, the launch site is entering another phase of expansion, one that represents its most unified and deliberate evolution so far. This latest expansion has been approved by both the U.S. Army Corps of Engineers and the National Oceanic and Atmospheric Administration, otherwise known as NOAA. The decision is documented in a four-page email from NOAA Acting Assistant Regional Administrator Thomas Payson Wilbur to Galveston District Commander Colonel Rhett Blackman. The approval confirms that all environmental reviews have been completed and that SpaceX has generated sufficient compensatory mitigation credits to offset projected impacts to wetlands and tidal flats. According to updated site plans, the launch site will expand southward, moving closer to the existing launch pads. Unlike earlier expansions that developed incrementally, this phase reflects a more cohesive planning strategy. The launch site will become a single contiguous area, defined by straight, clearly bounded edges. Once complete, the footprint of the launch site is expected to roughly double in size, reaching approximately 21 acres. The expanded area will be enclosed by security walls and feature five gated access points to manage traffic and operations. Inside the perimeter, a network of new roads will be built along the walls and through the interior, dividing the site into three distinct operational zones and supporting transportation, logistics, and emergency access. One of the key zones lies between the two existing launch pads and will be used to expand the tank bar, a critical upgrade to support higher launch cadence and more complex Starship operations. Southwest of Pad 2, SpaceX plans to add a staging pad, liquefied natural gas liquefaction facilities, additional ground support equipment, a water storage facility, a deflector farm, and an isolation and purging area. Southeast of Pad 1, similar infrastructure will be installed, including another staging pad, liquefied natural gas liquefaction systems, and expanded ground support equipment. This area will also include a dedicated zone for liquid methane production, reinforcing methane's central role in Starship operations. Together, these additions mark a major step forward for both the launch site and Starbase as a whole. One unresolved question is whether the new staging pads will eventually be developed into additional launch pads or repurposed to support rocket-catching towers for super-heavy recoveries. With approvals secured, SpaceX has already begun initial site work. Crews have excavated shallow trenches along the newly-defined boundaries and marked them with black identification strips. Much of the expanded area remains sandy and waterlogged, requiring reinforcement before heavy construction can begin, a process SpaceX has successfully employed elsewhere at Starbase. Further expansion at the test and production sites may eventually be needed, but for now, attention remains focused on how this latest launch site expansion will shape Starbase's future. Regarding regulatory approvals, there is another major development to highlight. SpaceX has just received authorization to move forward with a space-based data center. Only days after submitting its proposal, SpaceX obtained official approval from the FCC. The approval, detailed in a two-stage document, has now been published on the FCC's website. As outlined in the filing, the satellite constellation SpaceX envisions would be unprecedented in scale, reaching as many as one million satellites. For context, Starlink is already the largest satellite constellation in the world, yet its planned final size is approximately 12,000 satellites. This comparison illustrates the extraordinary scope of the system SpaceX is proposing. The project has received notable institutional support. In its notice, the FCC stated that this satellite system will represent the first step towards becoming a Kardashev Type II civilization, one that can harness the full power of the sun. In terms of operations, SpaceX explained that the satellites would function in a new, non-geostationary orbit regime. The system would primarily rely on optical inner-satellite links, allowing connections between satellites within the proposed network, as well as with satellites from SpaceX's first and second-generation Starlink constellations. The concept of space-based data centers has been mentioned frequently by Musk over the past year. Such a system would significantly simplify communications with space missions, improve tracking capabilities, and enhance the efficiency of research and exploration. It would also support humanity's ability to leverage Earth's resources more effectively and extend its reach deeper into the solar system. In addition, the network could serve as a critical resource for artificial intelligence development, an area that Musk has increasingly emphasized in relation to future spacecraft and rocket operations. Naturally, constructing a system of this magnitude will require substantial time and effort. To reduce that burden, SpaceX will need to rely on new launch capabilities. While Falcon 9 is highly reliable and flexible, launching 1 million satellites using that vehicle alone would take many years, even if SpaceX dedicated most of its annual launch capacity to the task. In this context, Starship stands out as the most practical solution. Starship is designed to eventually deliver between 100 and more than 200 tons to orbit per launch. Combined with full reusability and a rapid launch cadence, this capability would allow SpaceX to deploy extremely large numbers of satellites per flight. As a result, the proposed constellation would be completed far more quickly and with significantly lower overall cost. In this way, the emergence of the Space Data Center project further reinforces Starship's central role in SpaceX's long-term strategy. That said, both SpaceX and regulatory authorities must also address the potential risks. Earth orbit is already more congested than at any point in history. Introducing an additional 1 million satellites could increase collision risks for spacecraft, complicate mission planning, and pose serious challenges for astronomical observations. In the event of failures, such a constellation could also generate large amounts of orbital debris. Incidents like the recent malfunction of the Shenzhou-20 spacecraft underscore the real consequences of an increasingly crowded orbital environment. For this reason, mitigation strategies will be essential. These include precise orbital planning for different satellite groups, designs that minimize interference with astronomical observations, and spacecraft that can reliably and completely burn up in the atmosphere at the end of their operational lives. Implementing these measures is critical if humanity is to pursue sustainable and responsible expansion into space. And that brings us to the end of today's episode. Thank you so much for tuning in, and as always, this has been Kevin from GreatSpaceX. Until next time, keep looking up!
