SpaceX Falcon Heavy completes successful rehearsal, static fire pushed back due to bug in launch pad hardware

Published

on




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.

Musk bankers looking to trim xAI debt after SpaceX merger: report

xAI has built up $18 billion in debt over the past few years, with some of this being attributed to the purchase of social media platform Twitter (now X) and the creation of the AI development company. A new financing deal would help trim some of the financial burden that is currently present ahead of the plan to take SpaceX public sometime this year.

Elon Musk’s bankers are looking to trim the debt that xAI has taken on over the past few years, following the company’s merger with SpaceX, a new report from Bloomberg says.

xAI has built up $18 billion in debt over the past few years, with some of this being attributed to the purchase of social media platform Twitter (now X) and the creation of the AI development company. Bankers are trying to create some kind of financing plan that would trim “some of the heavy interest costs” that come with the debt.

The financing deal would help trim some of the financial burden that is currently present ahead of the plan to take SpaceX public sometime this year. Musk has essentially confirmed that SpaceX would be heading toward an IPO last month.

The report indicates that Morgan Stanley is expected to take the leading role in any financing plan, citing people familiar with the matter. Morgan Stanley, along with Goldman Sachs, Bank of America, and JPMorgan Chase & Co., are all expected to be in the lineup of banks leading SpaceX’s potential IPO.

Since Musk acquired X, he has also had what Bloomberg says is a “mixed track record with debt markets.” Since purchasing X a few years ago with a $12.5 billion financing package, X pays “tens of millions in interest payments every month.”

That debt is held by Bank of America, Barclays, Mitsubishi, UFJ Financial, BNP Paribas SA, Mizuho, and Société Générale SA.

X merged with xAI last March, which brought the valuation to $45 billion, including the debt.

SpaceX announced the merger with xAI earlier this month, a major move in Musk’s plan to alleviate Earth of necessary data centers and replace them with orbital options that will be lower cost:

“In the long term, space-based AI is obviously the only way to scale. To harness even a millionth of our Sun’s energy would require over a million times more energy than our civilization currently uses! The only logical solution, therefore, is to transport these resource-intensive efforts to a location with vast power and space. I mean, space is called “space” for a reason.”

The merger has many advantages, but one of the most crucial is that it positions the now-merged companies to fund broader goals, fueled by revenue from the Starlink expansion, potential IPO, and AI-driven applications that could accelerate the development of lunar bases.

SpaceX opened February 13 with a dual milestone at Cape Canaveral, featuring a successful Crew-12 astronaut launch to the International Space Station (ISS) and the first Falcon 9 booster landing at the company’s newly designated Landing Zone 40 (LZ-40). 

A SpaceX Falcon 9 lifted off at 5:15 a.m. Eastern from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station, placing the Crew Dragon Freedom into orbit on the Crew-12 mission. 

The spacecraft is carrying NASA astronauts Jessica Meir and Jack Hathaway, ESA astronaut Sophie Adenot, and Roscosmos cosmonaut Andrey Fedyaev, as noted in a report from Space News.

The flight marked NASA’s continued shift of Dragon crew operations to SLC-40. Historically, astronaut missions launched from Launch Complex 39A at Kennedy Space Center. NASA is moving Falcon 9 crew and cargo launches at SLC-40 to reserve 39A for Falcon Heavy missions and future Starship flights.

Crew-12 is scheduled to dock with the ISS on Feb. 14 and will remain in orbit for approximately eight months.

Beyond the crew launch, the mission also delivered a first for SpaceX’s Florida recovery operations. The Falcon 9 first stage returned to Earth and touched down at Landing Zone 40, a new pad built adjacent to SLC-40.

The site replaces Landing Zone 1, located several kilometers away, which has been reassigned by the U.S. Space Force to other launch providers. By bringing the landing area next to the launch complex, SpaceX is expected to reduce transport time and simplify processing between flights.

Bill Gerstenmaier, SpaceX’s vice president of build and flight reliability, stated that landing close to the pad keeps “launch and landing in the same general area,” improving efficiency. The company operates a similar side-by-side launch and landing configuration at Vandenberg Space Force Base in California.

Starlink terminals smuggled into Iran amid protest crackdown: report

Roughly 6,000 units were delivered following January’s unrest.

The United States quietly moved thousands of Starlink terminals into Iran after authorities imposed internet shutdowns as part of its crackdown on protests, as per information shared by U.S. officials to The Wall Street Journal

Roughly 6,000 units were delivered following January’s unrest, marking the first known instance of Washington directly supplying the satellite systems inside the country.

Iran’s government significantly restricted online access as demonstrations spread across the country earlier this year. In response, the U.S. purchased nearly 7,000 Starlink terminals in recent months, with most acquisitions occurring in January. Officials stated that funding was reallocated from other internet access initiatives to support the satellite deployment.

President Donald Trump was aware of the effort, though it remains unclear whether he personally authorized it. The White House has not issued a comment about the matter publicly.

Possession of a Starlink terminal is illegal under Iranian law and can result in significant prison time. Despite this, the WSJ estimated that tens of thousands of residents still rely on the satellite service to bypass state controls. Authorities have reportedly conducted inspections of private homes and rooftops to locate unauthorized equipment.

Earlier this year, Trump and Elon Musk discussed maintaining Starlink access for Iranians during the unrest. Tehran has repeatedly accused Washington of encouraging dissent, though U.S. officials have mostly denied the allegations.

The decision to prioritize Starlink sparked internal debate within U.S. agencies. Some officials argued that shifting resources away from Virtual Private Networks (VPNs) could weaken broader internet access efforts. VPNs had previously played a major role in keeping Iranians connected during earlier protest waves, though VPNs are not effective when the actual internet gets cut.

According to State Department figures, about 30 million Iranians used U.S.-funded VPN services during demonstrations in 2022. During a near-total blackout in June 2025, roughly one-fifth of users were still able to access limited connectivity through VPN tools.

Critics have argued that satellite access without VPN protection may expose users to geolocation risks. After funds were redirected to acquire Starlink equipment, support reportedly lapsed for two of five VPN providers operating in Iran.

A State Department official has stated that the U.S. continues to back multiple technologies,  including VPNs alongside Starlink, to sustain people’s internet access amidst the government’s shutdowns.
