SpaceX Falcon Heavy completes successful rehearsal, static fire pushed back due to bug in launch pad hardware
More than a decade after its 2005 public conception, SpaceX is closer than ever to the first launch Falcon Heavy, the company’s newest rocket. Earlier this afternoon, the vehicle was aiming for its first static fire test, in which all 27 of its engines would be ignited (nearly) simultaneously in order to test procedures and the rocket itself. This attempt was sadly scrubbed, but only after the vehicle apparently completed a successful wet dress rehearsal, which saw Falcon Heavy fully loaded with propellant. According to Orlando’s News 13, the attempt was scrubbed only after one of eight hold-down clamps showed signs of bugs.

While Falcon Heavy is not explicitly critical for SpaceX’s near-term launch business and its loftier future goals, the development and operation of such a massive launch vehicle will likely serve as a strong foundation as the company transitions more aggressively into the design, engineering, and manufacture of its still-larger BFR series of rocket boosters and upper stages. Falcon Heavy stands approximately as tall as Falcon 9 at around 70 m (230 ft), but features three times the thrust and a little less than three times the weight of SpaceX’s workhorse rocket. With 27 Merlin 1D engines to Falcon 9’s namesake nine, Falcon Heavy’s 22,800 kN (5,000,000 lbf) of thrust is a nearly inconceivably amount of power, equivalent to twenty Airbus A380 passenger jets at full throttle.
Why is Falcon Heavy important?
If SpaceX manages to pull off Falcon Heavy as a successful and reliable launch vehicle on the order of its reasonably successful Falcon 9, BFR may well be an easier vehicle to develop and operate, thanks to its single-core design. As Musk himself has discussed over the last year or so, the problem of safely and reliably distributing the thrust of Heavy’s side cores to the center core was unexpectedly difficult, as were the issues of igniting all 27 Merlin 1Ds and safely separating the side cores while in flight. Ultimately, the payload improvement (while in a fully reusable mode of operation) was quite small, particularly for the geostationary missions that make up essentially all prospective Falcon Heavy customer missions.
The additional complexity of recovery and refurbishing three separate Falcon 9 boosters almost simultaneously likely serves to only worsen the vehicle’s potential payoff, although the upcoming Block 5 iteration of Falcon 9 may partially improve the vehicle’s ease of operation. If Block 5 is indeed as reusable as SpaceX intends to make it, then a handful of Block 5 Falcon Heavy vehicles could presumably maintain a decent launch cadence for the vehicle without requiring costly and time-consuming shipping all over the continental US.

Nevertheless, the (hopefully successful) experience that will follow the launch and recovery operation of a super heavy-lift launch vehicle (SHLV) with ~30 first stage engines will be invaluable for SpaceX’s interplanetary goals. While BFR will be free of the complexity Falcon Heavy’s triple-core first stage added, it is still a massive vehicle that absolutely dwarfs anything SpaceX has attempted before. BFR in its 2017 iteration would mass around three times that of Falcon Heavy and feature 30 Raptor engines capable of approximately 53,000 kN (12,000,000 lbf) of thrust at liftoff, around 2.5x that of Heavy. Many, many other features mean that BFR and particularly BFS will be extraordinarily difficult to realize: BFS alone will be treading into truly unprecedented areas of spaceflight with the scale, longevity, and reusability it is intended to achieve while comfortably ferrying dozens of astronauts to and from Mars and the Moon.
However, the scale of BFR is equivalent to that of the famous Saturn V rocket that took astronauts to the Moon in the 1960s and 70s. In other words, while still dumbfoundingly massive and unprecedented in the modern era, rockets at the scale of BFR do in fact have a precedent of success, which lends the effort considerable plausibility, at least at proof-of-concept level. As of September 2017, Elon Musk suggested that SpaceX was aiming to begin construction of the first BFS (Big ____ Spaceship) by the end of Q2 2018, a truly Muskian deadline that probably wont hold. Still, if construction of the first prototype begins at any point in 2018, it will bode well for SpaceX’s aggressive timelines.

In the meantime, BFR’s precursor Falcon Heavy has effectively completed its first wet dress rehearsal, although the static fire attempt was scrubbed for the day. This is understandable for such a complex and untested vehicle, especially after SpaceX’s exceptionally quick modifications to Pad 39A. While unofficial, word is that an issue with one of the Transport/Erector/Launcher’s (TEL) eight separate launch clamps caused the scrub. Those launch clamps ensure that the massive vehicle would stay put during a static fire, and the status of those clamps would be especially important during such an unusually long static fire of such a powerful rocket.
Stay tuned for updates on SpaceX’s upcoming launches and Falcon Heavy’s next static fire attempt, likely within the next several days. The vehicle’s inaugural launch date is effectively up in the air until the static fire has been successfully completed, but as of yesterday SpaceX was understood to be targeting January 26th. Delays are to be expected.

Starship Flight 9 nears as SpaceX’s Starbase becomes a Texan City
SpaceX’s launch site is officially incorporated as Starbase, TX. Starship Flight 9 could launch on May 27, 2025.
SpaceX’s Starbase is officially incorporated as a city in Texas, aligning with preparations for Starship Flight 9. The newly formed city in Cameron County serves as the heart of SpaceX’s Starship program.
Starbase City spans 1.5 square miles, encompassing SpaceX’s launch facility and company-owned land. A near-unanimous vote by residents, who were mostly SpaceX employees, led to its incorporation. SpaceX’s Vice President of Test and Launch, Bobby Peden, was elected mayor of Starbase. The new Texas city also has two SpaceX employees as commissioners. All Starbase officials will serve two-year terms unless extended to four by voters.
As the new city takes shape, SpaceX is preparing for the Starship Flight 9 launch, which is tentatively scheduled for May 27, 2025, at 6:30 PM CDT from Starbase, Texas.
SpaceX secured Federal Aviation Administration (FAA) approval for up to 25 annual Starship and Super Heavy launches from the site. However, the FAA emphasized that “there are other licensing requirements still to be completed,” including policy, safety, and environmental reviews.
On May 15, the FAA noted SpaceX updated its launch license for Flight 9, but added: “SpaceX may not launch until the FAA either closes the Starship Flight 8 mishap investigation or makes a return to flight determination. The FAA is reviewing the mishap report SpaceX submitted on May 14.”
Proposed Texas legislation could empower Starbase officials to close local highways and restrict Boca Chica Beach access during launches. Cameron County Judge Eddie Trevino, Jr., opposes the Texas legislation, insisting beach access remain under county control. This tension highlights the balance between SpaceX’s ambitions and local interests.
Starbase’s incorporation strengthens SpaceX’s operational base as it gears up for Starship Flight 9, a critical step in its mission to revolutionize space travel. With growing infrastructure and regulatory hurdles in focus, Starbase is poised to become a cornerstone of SpaceX’s vision, blending community development with cutting-edge aerospace innovation.

United Airlines debuts Starlink Wi-Fi on Detroit flight
United’s first passenger flight with Starlink Wi-Fi just landed in Detroit. Mainline flights to follow by year-end.
United Airlines debuted Starlink Wi-Fi on its first passenger flight to Detroit, marking a milestone in in-flight connectivity with SpaceX’s satellite internet.
On Thursday, the morning flight from Chicago’s O’Hare International Airport introduced high-speed, gate-to-gate Starlink internet for United Airlines passengers. The Starlink-equipped United Embraer E-175, tail number UA5717, departed at 7:35 a.m. for Detroit Metropolitan Airport.
United announced the rollout on X, stating, “That lightning-fast Wi-Fi we told you about? It’s here. Our first customers just found out what it’s like to break the Wi-Fi barrier and stream, scroll, shop, and game just like at home with Starlink. And it’s FREE for MileagePlus members. Rolling out across our fleet now.”
The service leverages Starlink’s 7,000+ low Earth orbit (LEO) satellites to deliver broadband globally, including in remote areas. United is the only major U.S. airline currently offering Starlink. The airline plans to expand the service across its two-cabin regional fleet and introduce it on mainline flights by year-end.
Sean Cudahy from The Points Guy tested Starlink’s Wi-Fi pre-launch, praising its ease and reliability. “I ran a speed test, and it clocked the Wi-Fi at 217 Mbps of download speed, and 26.8 Mbps of upload speed,” Cudahy shared, noting its suitability for long flights.
Beyond aviation, SpaceX is pitching Starlink as a GPS alternative, emphasizing its potential for Positioning, Navigation, and Timing (PNT) services. This dual capability underscores Starlink’s versatility.
In a letter to the FCC, SpaceX wrote, “One opportunity stands out as a particularly ripe, low-hanging fruit: facilitating the rapid deployment of next-generation low-Earth orbit (‘LEO’) satellite constellations that can deliver PNT as a service alongside high-speed, low-latency broadband and ubiquitous mobile connectivity.”
As SpaceX expands Starlink’s applications, from aviation to navigation, United’s adoption signals a broader shift toward satellite-driven connectivity on long flights. With plans to equip more aircraft, United and Starlink are redefining in-flight internet, promising seamless digital access at 30,000 feet.

SpaceX touts Starlink as GPS alternative in FCC PNT push
SpaceX highlighted Starlink’s potential to deliver PNT services alongside its broadband offerings.
SpaceX is positioning its Starlink constellation as a viable GPS alternative. In a letter to the Federal Communications Commission (FCC), SpaceX stated that it could leverage Starlink satellites for next-generation Positioning, Navigation, and Timing (PNT) solutions.
GPS has been run through a single provider in the United States, the Defense Department. The FCC intends to use Positioning, Navigation, and Timing (PNT) solutions to complement GPS technologies. In its letter, SpaceX highlighted Starlink’s potential to deliver PNT services alongside its broadband offerings in its letter to the FCC.
“As the Commission identifies specific actions to contribute to the whole-of-government PNT system resilience effort, one opportunity stands out as a particularly ripe, low-hanging fruit: facilitating the rapid deployment of next-generation low-Earth orbit (‘LEO’) satellite constellations that can deliver PNT as a service alongside high-speed, low-latency broadband and ubiquitous mobile connectivity,” SpaceX wrote.
SpaceX also emphasized its ongoing work to integrate PNT into its cellular Starlink service, which is expected to be launched with T-Mobile in July. The private space provider also stated that Starlink satellites already operate independently of GPS. This lays the groundwork for resilient PNT delivery across authorized frequencies, SpaceX noted in its letter.
“SpaceX has also been actively working to integrate PNT solutions into its direct-to-device commercial service offerings. In so doing, SpaceX can advance the Commission’s goal in this proceeding to maintain American leadership in next-generation PNT services both here at home and in over 130 countries it serves around the world.
“SpaceX looks forward to playing an integral role in creating a more robust, resilient, and secure PNT ecosystem for Americans and people around the world,” SpaceX noted.
SpaceX also advocated for a “technology-neutral approach” to GPS alternatives in its letter, while critiquing EchoStar’s unused 2GHz spectrum for mobile satellite services. Meanwhile, Globalstar, Apple’s satellite provider, also pitched its services as a GPS complement, stating that its services “can function as either an alternative or a complement to GPS.”
“Notably, Globalstar’s satellites transmit outside of the L-band, which provides PNT users with added immunity from GPS jamming and spoofing. In addition, Globalstar’s satellite transmissions at 2.4GHz are stronger than GPS signals, bolstering resilience, performance, and reliability,” GlobalStar noted.
