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.

Elon Musk has revealed the tentative timeframe for Starship’s next milestone that would push the spacecraft’s reusability to a whole new level. 

Following Flight 11’s flawless mission, Musk noted on X that SpaceX will be aiming to catch the Starship Upper Stage with its launch tower as early as spring 2026. This should pave the way for SpaceX to start optimizing Starship for maximum reusability.

Flight 11 closes the Starship V2 chapter on a high note

Starship’s eleventh flight, which launched from Starbase, Texas, achieved every major mission objective. The Super Heavy booster completed a successful ascent, hover, and soft splashdown in the Gulf of America, while the upper stage executed an orbit burn, deployed Starlink simulators, and returned with a controlled reentry over the Indian Ocean.

This mission officially closed the chapter on the second-generation Starship and first-generation Super Heavy booster, and it set the stage for a redesigned vehicle built for orbital payload missions, propellant transfer, and beyond. It should be noted that Elon Musk has mentioned on X that Starship V3, at least if things go well, might be capable of reaching Mars.

Elon Musk confirms tower catch attempt set for spring

After Flight 11’s success, Musk confirmed that SpaceX will attempt to catch the Starship Upper Stage with its launch tower arms, fondly dubbed by the spaceflight community as “chopsticks,” in the coming months. Musk’s announcement came as a response to an X user who asked when the tower could start catching the Starship Upper Stage. In his reply, Musk simply wrote “Springtime.”

Starship’s reusability is a key feature of the spacecraft, with SpaceX aiming to achieve a launch cadence that is almost comparable to conventional aircraft. For such a scenario to be feasible, launch tower catches of both Starship’s Upper Stage and its Super Heavy booster have to be routine.

SpaceX is preparing to launch its final Starship V2 rocket on October 13, 2025. The launch closes the curtain on Starship V2 and marks the start of the ambitious spacecraft’s V3 era. 

Liftoff for Flight 11 is scheduled for 7:15 p.m. ET from Starbase in South Texas, with a 75-minute launch window. The mission will test reentry dynamics, new landing burn configurations, and heat-shield upgrades ahead of the transition to the next-generation Starship V3.

Starship V3 and beyond

Elon Musk confirmed on X that Starship V3 is already in production and could be “built & tested” and perhaps even flown before the end of 2025. The new version is expected to feature major performance and scale improvements, with Musk stating that Starship V3, provided that things go well, might be capable of reaching Mars, though V4 is more likely to perform a full-scale mission to the red planet. 

“Only one more V2 left to launch,” Musk wrote back in August following Starship’s successful Flight 10 mission. In another post, Musk stated that “Starship V3 is a massive upgrade from the current V2 and should be through production and testing by end of year, with heavy flight activity next year.”

Starship V2’s final mission

Flight 11 is designed to push the limits of Starship V2. SpaceX engineers have intentionally removed heat-shield tiles in vulnerable areas to analyze how the vehicle handles atmospheric reentry under stress, as noted in a Space.com report. The test will also refine subsonic guidance algorithms and new landing burn sequences for the Super Heavy booster that would be used for Starship V3.

“Super Heavy will ignite 13 engines at the start of the landing burn and then transition to a new configuration with five engines running for the divert phase. Previously done with three engines, the planned baseline for V3 Super Heavy will use five engines during the section of the burn responsible for fine-tuning the booster’s path, adding additional redundancy for spontaneous engine shutdowns. 

“The booster will then transition to its three center engines for the end of the landing burn, entering a full hover while still above the ocean surface, followed by shutdown and dropping into the Gulf of America,” SpaceX wrote in a post on its official website.

The Philippines’ Department of Information and Communications Technology (DICT) is using Starlink to provide connectivity in the municipality of Masbate, which was affected by Severe Tropical Storm Opong (international name Bualoi). 

The Severe Tropical Storm battered the province, leaving communications networks in the area in shambles.

Starlink units enhance connectivity

DICT Secretary Henry Aguda visited the province to assess internet and communications infrastructure and deliver 10 additional Starlink satellite units, according to the Philippine News Agency. The is move aimed at strengthening emergency response and restore digital access to the area.

Aguda met with Masbate Governor Richard Kho during his visit and joined telecommunications representatives in inspecting provincial offices, free charging stations, and Wi-Fi connectivity sites for residents. 

According to DICT officer-in-charge Rachel Ann Grabador, three Starlink units, 10 routers, and a 2kW solar-powered station have already been deployed in the province following the typhoon. The units have been installed at key facilities such as Masbate Airport’s communications tower and the Masbate Provincial Hospital’s administrative office.

Game-changing technology

Thanks to its global coverage and its capability to provide high-speed internet connectivity even in remote areas, Starlink has become the best communications solution that can be deployed in the aftermath of natural disasters. Its low-cost kits, which are capable of of providing fast internet speeds, are also portable, making them easy to deploy in areas that are damaged by natural disasters.

As noted in a Space.com report, there are currently 8,475 Starlink satellites in orbit, of which 8,460 are working, as of September 25, 2025. Initially, SpaceX had filed documents with International regulators to place about 4,000 Starlink satellites in Low Earth Orbit. Over time, however, the number of planned Starlink satellites has grown, with SpaceX aiming to launch as many as 42,000 Starlink satellites to fully connect the globe.
