SpaceX fires Falcon Heavy’s 27 booster engines ahead of “most difficult launch ever”
For the third time ever, SpaceX has successfully performed a critical static-fire test of an integrated Falcon Heavy, briefly igniting all 27 of its Merlin 1D engines to verify the health and readiness of the rocket.
Per SpaceX’s official confirmation, a “quick-look” inspection of static fire telemetry has indicated that the company’s Falcon Heavy rocket is ready for its second launch in less than three months, a milestone that could also allow both flight-proven side boosters to tie SpaceX’s own record for booster turnaround. Falcon Heavy Flight 3 is now scheduled to launch the US Air Force’s Space Test Program 2 (STP-2) mission no earlier than 11:30 pm ET (03:30 UTC), June 24th. According to SpaceX CEO Elon Musk, the mission will unequivocally be the company’s “most difficult launch ever”.
Coincidentally, on top of being Falcon Heavy’s first scheduled night launch, STP-2 has now also marked the massive rocket’s first nighttime static fire. During this critical test, Falcon Heavy briefly ignites all 27 of its three boosters’ Merlin 1Ds and throttles the engines up to full thrust, much like airliners sometimes set their brakes and throttle up before attempting to take off. The difference between Falcon Heavy and passenger aircraft is nevertheless rather significant, given that Falcon Heavy produces ~15x the thrust of an A380 – the world’s most powerful mass-produced passenger aircraft – at liftoff: 22,820 kN (5.1M lbf) to the massive jet’s meager 1,440 kN (0.3M lbf).
Despite all of that thrust, Falcon Heavy is held down during static fire by eight accurately-named hold-down clamps, themselves a part of a massive transport/erector, which is itself anchored directly to Pad 39A’s concrete foundation. In short, Falcon Heavy (and especially Falcon 9) is not going anywhere until those hold-down clamps are explicitly released. Thanks to SpaceX’s avoidance of the solid rocket boosters used by almost every other modern launch vehicle, Falcon 9 and Heavy rockets can abort at any point prior to clamp release, offering a uniquely broad abort capability.
As such, not only does SpaceX’s dedicated pre-launch static fire fully test the rocket’s health, but the same procedure is essentially repeated in the seconds before clamp release during an actual orbital launch attempt. If at any point Falcon 9’s autonomous onboard computer decides that it doesn’t like any of the thousands of channels of telemetry it’s constantly analyzing, it can command an engine shutdown and total launch abort even if all first stage engines have already ignited and reached full thrust. If routine McGregor, TX acceptance testing – also involving a full static fire – is accounted for, every single Falcon 9 booster technically completes three fully-integrated static fires before its inaugural liftoff. Falcon Heavy is slightly different, as each booster is independent test-fired in Texas but the integrated rocket can only perform static fires at Pad 39A.
After those three critical tests, flight-proven Falcon boosters are subjected to the less stringent few-second static fires SpaceX performs at the launch pad 3-7 days before a given launch. With Falcon Heavy Flight 3, the rocket’s center core, upper stage, and payload fairing are all brand new, fresh from either SpaceX’s Hawthorne factory or McGregor acceptance testing. However, both side cores – Block 5 boosters B1052 and B1053 – are flight-proven, having successfully completed their first launches and landings on April 11th, less than 70 days ago.
Set by regular old Falcon 9 boosters, SpaceX’s current record for booster turnaround time (time between two launches) is 71 days (set in June 2018), while the Block 5 upgrade’s record stands at 74 days (set in October 2018). If Falcon Heavy’s STP-2 launch holds strong on June 24th, B1052 and B1053 will simultaneously tie SpaceX’s Block 5 turnaround record. This would be accomplished despite the added pressure from the US Air Force’s decision to use STP-2 as a sort of dress rehearsal for certifying all flight-proven commercial rockets, an honor (and burden) that likely added extra work, oversight, and scrutiny to the process of refurbishing and relaunching B1052 and B1053.
“[T]he US Air Force has decided that STP-2 presents an excellent opportunity to begin the process of certifying flight-proven SpaceX rockets for military launches. The STP-2-related work is more of a preliminary effort for the USAF to actually figure out how to certify flight-proven commercial rockets, but it will still be the first time a dedicated US military mission has flown on a flight-proven launch vehicle. Down the road, the processes set in place thanks – in part – to STP-2 and Falcon Heavy may also apply to aspirational rockets like Blue Origin’s New Glenn and ULA’s “SMART” proposal for Vulcan reuse.”

In a last-second surprise, SpaceX updated Falcon Heavy center core B1057’s planned drone ship landing site from a brief 40 km (25 mi) to more than 1240 km (770 mi) off the coast of Florida. SpaceX set its current record for recovery distance less than three months ago during Falcon Heavy’s commercial launch debut, in which Block 5 center core B1055 landed nearly 970 km (600 mi) offshore on drone ship Of Course I Still Love You (OCISLY). If all goes well, B1057 – the second finished Block 5 center core – will absolutely crush its predecessor’s record, implying that the booster will likely be subjected to SpaceX’s most difficult reentry and recovery yet.

Starlink gets its latest airline adoptee for stable and reliable internet access
The company said it plans to “rapidly integrate Starlink into its fleet,” and that the first Starlink-equipped aircraft will enter service this Summer.
SpaceX’s Starlink, the satellite internet program launched by Elon Musk’s company, has gotten its latest airline adoptee, offering stable and reliable internet to passengers.
Southwest Airlines announced on Wednesday that it would enable Starlink on its aircraft, a new strategy that will expand to more than 300 planes by the end of the year.
The company said it plans to “rapidly integrate Starlink into its fleet,” and that the first Starlink-equipped aircraft will enter service this Summer.
Tony Roach, Executive Vice President, Chief Customer and Brand Officer for the airline, said:
“Free WiFi has been a huge hit with our Rapid Rewards Members, and we know our Customers expect seamless connectivity across all their devices when they travel. Starlink delivers that at-home experience in the air, giving Customers the ability to stream their favorite shows from any platform, watch live sports, download music, play games, work, and connect with loved ones from takeoff to landing.”
Southwest also said that this is just one of the latest upgrades it is making to provide a more well-rounded experience to its aircraft. In addition to Starlink, it is updating cabin designs, offering more legroom, and installing in-seat power to all passengers.
Southwest became one of several airlines to cross over to Starlink, as reviews for the internet provider have raved about reliability and speed. Over the past year, Hawaiian Airlines, United Airlines, Alaska Airlines, airBaltic, Air France, JSX, Emirates, British Airways, and others have all decided to install Starlink on their planes.
This has been a major move away from unpredictable and commonly unreliable WiFi offerings on planes. Starlink has been more reliable and has provided more stable connections for those using their travel time for leisure or business.
Jason Fritch, VP of Starlink Enterprise Sales at SpaceX, said:
“We’re thrilled to deliver a connectivity experience to Southwest Airlines and its Customers that really is similar, if not better, than what you can experience in your own home. Starlink is the future of connected travel, making every journey faster, smoother, and infinitely more enjoyable.”
Starlink recently crossed a massive milestone of over 10 million subscribers.

Tesla nears closure of Full Self-Driving purchasing option
The move to bring FSD to this type of purchasing program comes after CEO Elon Musk noted in January that Tesla would move away from the outright purchase option.
Tesla is nearing the closure of its Full Self-Driving outright purchasing option, which will be removed on February 14, meaning Saturday will be the last time it can be bought as a non-subscription.
Tesla is aiming to move its Full Self-Driving suite to a subscription-only platform, a move that will enable people to only pay monthly for the semi-autonomous driving functionality.
The move to bring FSD to this type of purchasing program comes after CEO Elon Musk noted in January that Tesla would move away from the outright purchase option.
It is currently priced at $8,000 for the outright option to use Full Self-Driving, a substantial decrease compared to the $15,000 it was priced at one time. For the monthly subscription, it is just $99 per month, but that price will change, likely increasing as things get more advanced.
Tesla is overhauling its Full Self-Driving subscription for easier access
We say it will likely increase because there is no indication of how Tesla will price FSD. There has been some speculation that Tesla could utilize a tiered system to price FSD, which would potentially allow owners to pick and choose a set of features that would be most ideal for them.
This would potentially introduce an even more affordable option for FSD use, but this is unconfirmed. The reason many say this could be an option for Tesla is the fact that if the price goes up further, the take rate, which is currently around 12 percent at its most recent estimate, could be lower.
Musk needs 10 million active Full Self-Driving subscriptions to unlock one of the tranches of his newest compensation package.
The move to a subscription-only platform has its positives and negatives, and owners have been more than vocal about these since Musk confirmed the move.
Positives
- Lower barrier to entry and higher potential adoption
- Financially better for many users
- Easier transfers and brand loyalty
- Predictable recurring revenue for Tesla
- Access to the latest features
Negatives
- Higher long-term cost for loyal/long-term owners
- No true “ownership” or permanence
- Risk of future price hikes or even deactivation
- Perceived as of less value
- Impact on resale and used market
Overall, there is a split among the Tesla community in terms of what they see as the “right” way to handle this. Tesla is likely to shed more details on what its plans for the subscription-only platform will be, including pricing, in the coming weeks.

Elon Musk’s Boring Company selected for Universal Orlando tunnel project
The underground transport tunnel is designed to address the persistent gridlock surrounding International Drive.
Elon Musk’s The Boring Company has been selected for a proposed underground transit system connecting Universal Orlando Resort and the newly opened Universal Epic Universe.
The underground transport tunnel is designed to address the persistent gridlock surrounding International Drive.
As noted in a blooloop report, Universal’s Shingle Creek Transit and Utility Community Development District approved a resolution showing its intent to designate The Boring Company as the contractor for the project.
The agreement covers the full scope of the project, from the tunnel’s design, construction, and maintenance. The project has also been described in public documents as a “point-to-point innovative transportation” initiative with a 25-year agreement.
The proposed Boring Company tunnels would directly link Universal’s existing parks with Epic Universe, which sits roughly three miles away from Universal Orlando Resort. Today, buses are the only direct connection between the two destinations.
Project requirements were quite stringent. Bidders were required to demonstrate at least $75 million in bonding capacity, have a minimum of seven years of operational experience, and show prior delivery of a comparable project valued at $25 million or more within the past 15 years. The Boring Company, thanks in no small part to the Vegas Loop, meets these requirements.
The Orlando selection adds to The Boring Company’s growing portfolio of Loop-style systems. In Las Vegas, the Las Vegas Convention Center Loop has transported more than two million passengers in Tesla vehicles through underground tunnels since 2021. The greater Vegas Loop system is also under construction.
For now, residents in the area seem enthusiastic about the upcoming project. In a comment to Fox35, residents noted that the tunnels could improve traffic in the area.
“We are very congested at certain times and certain hours and that would certainly help with people not having to budget their time,” Mary Walters-Clark, a resident, stated. Another resident, Scott Heinz, echoed similar sentiments. “I think it would be a new opportunity to lessen traffic load and good for visitors as well,” he said.
The tunneling startup has started bringing its Loop projects to international locations. It recently signed a memorandum of understanding with Dubai’s Roads and Transport Authority to explore the development of a 17-kilometer underground Loop network beneath Dubai.
