SpaceX’s first Block 5 Falcon Heavy days away from critical static fire test

The first commercial launch of SpaceX’s Falcon Heavy rocket – this time in a Block 5 configuration – is as few as ten days away from a targeted window beginning at 6:36 pm EST (22:36 UTC), April 7th. That target hinges on whether Falcon Heavy is ready and able to roll out to Pad 39A and successfully conduct its first integrated static fire, currently scheduled on April 1st.

The payload for this mission – communications satellite Arabsat 6A – had its original Lockheed Martin manufacturing and SpaceX launch contracts signed back in the first half of 2015, while the 6000 kg (13,200 lb) spacecraft was effectively completed once it was shipped from California to Florida at the start of 2019. After approximately 12 months of delays from an original launch target shortly after Falcon Heavy’s 2018 debut, Arabsat 6A’s four-year journey will hopefully reach completion in a geostationary transfer orbit. At the same time, the US Air Force says that it will be watching this launch – and the one meant to follow soon after – as a critical test along the path to fully certifying the powerful rocket for military launches.

As a pathfinder for an unproven rocket, SpaceX’s first Falcon Heavy launch suffered a number of likely minor to moderate anomalies as company engineers and technicians learned for the first time how the rocket actually behaves in the real world, under real-world conditions and operations. Case in point, the first integrated Falcon Heavy was taken through its first wet-dress rehearsal – in which the vehicle is filled with a flight load of fuel and oxidizer – on January 11th. An anomaly required additional work and took nearly two weeks to resolve, culminating in the rocket’s first (and successful) static fire on January 24th. An additional two weeks after that, SpaceX went ahead with the first attempted launch of Falcon Heavy with great success, pushing the T-0 back several hours due to weather but ultimately completed an almost flawless debut, aside from an anomaly that caused the center core to impact the ocean surface at high speeds.

Despite the invaluable experience gained by those orchestrating the launch and those who built the vehicle, Falcon Heavy’s second launch may result in similar teething pains, particularly due to the fact that the rocket’s complete upgrade to Block 5 hardware likely necessitated significant design changes across the board. In other words, the rocket SpaceX aims to launch in early April may be quite a bit different from the vehicle that launched 14 months prior, creating much of the same uncertainty inherent in the first launch(es) of any new rocket. Still, many of the complex boosters’ connection and separation mechanisms that were flight-tested for the first time that February were likely more or less unchanged in the move from Block 2/3 to Block 5 hardware.

“Again, I don’t want to tempt fate. But this is a much stronger octaweb structure. It’s made of a much higher strength of bolted aluminum. A 7000 series instead of a 2000 series. So the strength of the octaweb is dramatically greater. It also has quite a bit of thermal protection in case there’s say, an engine fire, or something like that. Such that it does not melt the octaweb.” – SpaceX CEO Elon Musk, May 2018

“Biggest process change [for Block 5] was eliminating Tig welding of the thrust structure or “Octaweb” and the move to a bolted design but this made it much easier and faster to produce overall as well.” – SpaceX VP of Production Andy Lambert, April 2018

A step further, SpaceX CEO Elon Musk has indicated that one major section of Block 5 upgrades – moving from a welded to a bolted thrust structure (i.e. octaweb) – was expected to be a boon for Falcon Heavy, while also making octawebs far easier to manufacture, assemble, and even disassemble. According to Musk, new bolted octawebs are also “dramatically” stronger, a boon for Falcon Heavy boosters – particularly the center core – that need to survive forces multiple times stronger than those subjected upon Falcon 9 first stages.

Meanwhile, according to comments made by Air Force officials to Spaceflight Now, the USAF is looking at SpaceX’s Arabsat 6A and subsequent STP-2 Falcon Heavy launches as critical steps along the way to fully certifying the rocket for valuable military payloads. Currently, the only option available for military and NRO payloads past a certain weight or in need of exceptionally high-energy orbits is ULA’s Delta IV Heavy rocket, an extremely expensive ($300M+ per launch) rocket with a bad track record of schedule reliability.

An Air Force spokesperson this week confirmed the agreement to use previously-flown side boosters for the STP-2 mission. The center core will be new for the Arabsat 6A and STP-2 launches.

“This provides an early opportunity for the Air Force to understand the process for using previously-flown hardware with the goal to open future EELV missions to reusable launch vehicles,” the spokesperson said in response to an inquiry from Spaceflight Now.

Given that STP-2 will need to reuse both of the Arabsat 6A Falcon Heavy’s side boosters, the USAF official also specifically noted that the military branch would be examining SpaceX’s refurbishment processes and the performance of the flight-proven stages with the intention of ultimately allowing reused rockets to launch military satellites. As such, the successful launch, landing, refurbishment, and re-launch of both Falcon Heavy side boosters (B1052 & B1053) will be doubly critical for SpaceX.

SpaceX is set to expand its presence in Central Texas with an $8 million project to enlarge its Bastrop facility, as per state filings. 

The 80,000-square-foot addition, which is scheduled to begin construction on September 24 and wrap in early January 2026, was registered with the Texas Department of Licensing and Regulation and initially reported by My San Antonio

New investment

Bastrop is already the site of several Elon Musk-led ventures. The upcoming expansion will extend SpaceX’s office at 858 FM 1209, near Starlink’s operations and The Boring Company’s facilities. Just down the road, X is housed in the Hyperloop Plaza at 865 FM 1209.

SpaceX’s expansion reflects a steady buildup of resources in Bastrop since the private space firm established its presence in the area. The addition was praised by Tesla Governor Greg Abbott, who wrote on X that the expansion will “bring more jobs, innovations and will strengthen Starlink’s impact worldwide.” 

State support

In March, Gov. Greg Abbott announced a $17.3 million state grant to SpaceX for an “expansion of their semiconductor research and development (R&D) and advanced packaging facility in Bastrop.” The project is expected to create more than 400 new jobs and generate over $280 million in capital investment.

Following the grant award, the Texas Governor also noted that SpaceX’s facility would be growing by 1 million square feet across three years to boost its Starlink program. SpaceX’s Starlink division is among the company’s fastest-growing segments, with the satellite internet system connecting over 6 million users and counting worldwide. 

Recent reports have also indicated that Starlink has struck a deal with EchoStar to acquire 50 MHz of exclusive S-band spectrum in the United States and global Mobile Satellite Service (MSS) licenses. This should pave the way for Starlink to provide 5G coverage worldwide, even in remote areas.

SpaceX has struck a deal with EchoStar to acquire 50 MHz of exclusive S-band spectrum in the United States and global Mobile Satellite Service (MSS) licenses, paving the way for its next-generation Starlink Direct to Cell constellation. 

The agreement strengthens Starlink’s ability to expand its mobile coverage worldwide. With the upgraded system, SpaceX aims to deliver full 5G connectivity to unmodified cell phones and eliminate mobile dead zones worldwide.

Expanding mobile coverage

Starlink’s Direct to Cell service was first launched in early 2024 with satellites designed to connect directly to standard LTE mobile devices. Within days of deployment, engineers demonstrated texting from unmodified phones, followed by video calling. Over the past 18 months, SpaceX has grown the system to more than 600 satellites, which now offer service across five continents. Today, Starlink Direct to Cell is considered the largest 4G coverage provider worldwide, connecting over 6 million users and counting, according to SpaceX in a post.

The constellation integrates with Starlink’s broader fleet of 8,000 satellites via a laser mesh network. Operating at 360 kilometers (224 miles) above Earth, the satellites connect directly to devices without hardware or firmware modifications. The system is already supporting messaging, video calls, navigation, social media apps, and IoT connectivity in remote areas.

Next-generation system

Through its new EchoStar spectrum acquisition, SpaceX plans to develop a second-generation constellation with far greater capacity. The upgraded satellites will leverage SpaceX-designed silicon and advanced phased array antennas to increase throughput by 20x per satellite and increase total system capacity by more than 100x. These enhancements are expected to support full 5G cellular connectivity in remote areas, with performance comparable to terrestrial LTE networks.

Partnerships with major mobile carriers remain central to Starlink’s expansion. Operators including T-Mobile in the United States, Rogers in Canada, KDDI in Japan, and Kyivstar in Ukraine are integrating Direct to Cell services for coverage in rural areas and during emergencies. The service has already provided critical communication during hurricanes, floods, and wildfires, enabling millions of SMS messages and emergency alerts to be delivered when ground networks were unavailable.

The Federal Aviation Administration (FAA) has wrapped up a series of public hearings on SpaceX’s proposal to launch its Super Heavy Starship rocket from NASA’s Kennedy Space Center (KSC). 

The sessions, held both in-person and online, form part of the draft environmental impact statement (EIS) review that will determine whether SpaceX would be cleared to conduct Starship launches and landings from Florida’s Space Coast.

FAA review and Starship launch plans

According to the FAA’s draft EIS, SpaceX seeks permission to fly its fully reusable Starship system from Launch Complex 39A, where construction of a dedicated tower and infrastructure has already begun. Proposed operations could involve landings at KSC or droneships positioned across the Atlantic, Pacific, and Indian Oceans. The FAA emphasized that final approval is not guaranteed with the completion of the EIS, as safety and financial requirements must still be met, as noted in a Space.com report.

Starship’s larger scale compared to Falcon 9 means expanded exclusion zones for air, sea, and beach access. The analysis also projected more than 60 annual closures of Playalinda Beach, alongside potential flight delays across Florida airports lasting 40 minutes to two hours. Port Canaveral would also be affected by maritime restrictions.

Local concerns

Public comments reflected a mix of optimism and unease. Aviation officials, such as Tampa International Airport COO John Tiliacos, warned of significant disruption to commercial flights. “There is the potential that there’s going to be significant impact to commercial aviation and the traveling public. That’s something that certainly the FAA needs to give consideration to and, frankly, come up with a plan to mitigate,” he stated.

Others raised health concerns, noting that chronic sleep disruption from launch noise could impact veterans and trauma survivors. Robyn Memphis, a neuroscience and psychology graduate student, stated that sleep disruptions from launch noise and sonic booms could carry lasting effects. “Chronic sleep disruption is not just inconvenient. This is directly linked to depression, anxiety… cardiovascular disease, even suicide risk. And being in Florida, we have many veterans and trauma survivors in the community,” she said.

Nudist protests and responses

Erich Schuttauf, the executive director of the American Association for Nude Recreation, also argued that places like Playalinda Beach, a nudist beach, are crucial for people who travel to places where public nudity is legal. His sentiments were echoed by fellow nudist Sue Stevens, who noted that “It’s probably a quarter million people that travel and think like I do, who look for destinations that are beautiful and surrounded by like-minded people.”

Photographer Max West, who plans to move to Florida to photograph Starship, noted that the spacecraft presents a notable step forward for humanity. And while its impact to communities is not marginal, the progress it offers is well worth it. “I’m not going to say that there is zero environmental impact there,” he said, though he also stated that there has to be some “little sacrifices along the way. “The turtles and the nudists will have to migrate. That’s the cost that you have to pay for this incredible stuff that’s happening.”
