In an unexpected last-second change, SpaceX has moved Falcon Heavy Flight 3’s center core landing on drone ship Of Course I Still Love You (OCISLY) from 40 km to more than 1240 km (770 mi) off the coast of Florida.

Drone ship OCISLY is already being towed to the landing site, necessary due to the sheer distance that needs to be covered at a leisurely towing pace. The current record for distance traveled during booster recovery was set at ~970 km by Falcon Heavy center core B1055 in April 2019. If successful, Falcon Heavy center core B1057 will smash that record by almost 30% after sending two dozen spacecraft on their way to orbit. Falcon Heavy Flight 3 is scheduled to lift off in support of the Department of Defense’s Space Test Program 2 (STP-2) mission no earlier than 11:30 pm ET (03:30 UTC), June 24th. A routine static fire test at Pad 39A will (hopefully) set the stage for launch on Wednesday, June 19th.

This comes as a significant surprise for several reasons. First and foremost, the difference between a center core landing 40 km or 1300 km from the launch site is immense. For Falcon Heavy, the center core shuts down and separates from the rest of the rocket as much as a minute after the rocket’s two side boosters, potentially doubling the booster’s relative velocity at separation.

That extra minute of acceleration means that the center core can easily be 50-100+ km downrange at the point of separation. In other words, landing 40 km offshore aboard drone ship OCISLY would be roughly akin to a full boostback burn, meaning that the center core would need to nullify all of its substantial downrange velocity, turn around, and fly ~50-100 km back towards the launch site. Being able to perform such an aggressive maneuver would indicate that Falcon Heavy’s boost stage has a huge amount of propellant (delta V) remaining after completing its role in the launch.

To have STP-2’s center core recovery moved from 40 km to 1240 km thus indicates an absolutely massive change in the rocket’s mission plan and launch trajectory. For reference, Falcon Heavy Flight 2’s Block 5 center core (B1055) set SpaceX’s current record for recovery distance (970 km/600 mi) after launching Arabsat 6A – a massive ~6500 kg (14,300 lb) satellite – to a spectacularly high transfer orbit of >90,000 km (56,000 mi).

Why so spicy?

There are three obvious possibilities that might help explain why the STP-2 mission has abruptly indicated that it will require SpaceX’s most energetic booster recovery yet.

1. STP-2 is carrying at least 1-2 metric tons worth of mystery payload(s)

This is highly unlikely. The USAF SMC has already released a SpaceX photo showing the late stages of the STP-2 payload stack’s encapsulation inside Falcon Heavy’s payload fairing. Short of an elaborate faked encapsulation followed by the installation of additional mysterious spacecraft or some extremely dense hardware hidden inside, it’s safe to say that the STP-2 payload stack weighs what the USAF says it weighs, which is to say not nearly heavy enough to warrant a record-smashing booster recovery given the known orbital destinations.

The USAF further confirmed that there is no ballast on the stack, removing the possibility of a lead weight or steel boilerplate meant to artificially push Falcon Heavy to its limits.

2. STP-2’s already-challenging Falcon upper stage mission profile is even more exotic than described

Per official mission overviews, it’s already clear that STP-2 could be the most challenging launch ever attempted for SpaceX’s orbital Falcon upper stage. According to SpaceX itself, “STP-2…will be among the most challenging launches in SpaceX history, with four separate upper-stage engine burns, three separate deployment orbits, a final propulsive passivation maneuver, and a total mission duration of over six hours.”

While undeniably challenging, it’s not clear why it would require such a high-energy center core recovery. With a payload mass of just ~3700 kg, Falcon 9 has launched much larger payloads to (relatively) higher orbits, but this fails to account for the added challenge of long coasts and multiple different orbits. Also of note, the above graph (courtesy of a years-old USAF document) appears to disagree with SpaceX’s description of “four… upper-stage burns”, instead showing five burns (red spikes).

More likely than not, OCISLY’s ~1200-kilometer move can be explained largely by the reintroduction of what the above graph describes as the Falcon upper stage’s “disposal burn”, likely referring to a deorbit burn. On top of the delta V already required for the first four burns, it isn’t out of the question that an additional coast and deorbit burn from 6000 km (3700 mi) would push the recovery equation in favor of attempting to incinerate center core B1057.

3. USAF/DoD conservatism strikes again?

The last plausible explanation for this radical shift is that the US Air Force/Department of Defense (DoD) has decided last-second that they want more margins on top of their already-overflowing safety margins, quite literally pushing B1057 to the edge of its performance envelope to mitigate low-probability failure modes. This has been done to an even more extreme extent with the US Air Force’s recent GPS III SV01 launch, in which SpaceX was forced to expend a new Falcon 9 Block 5 booster to provide the extreme safety margins the USAF desired.

According to the USAF, the STP-2 mission – including launch costs – represents as much as $750M, coincidentally similar to the estimated cost of the GPS III SV01 satellite and an expendable Falcon 9 rocket. As such, it’s not out of the question that a similar level of paranoia/conservatism is in play for STP-2.

Numbers 2 and 3 are equally plausible explanations for this last-second booster recovery shift. Given the US military’s active involvement, it’s more likely than not that no explanations will be offered. Regardless, this surprise development is bound to result in a truly spectacular recovery attempt for SpaceX’s second Block 5 center core and will likely involve breaking several still-fresh records in the process.

Falcon Heavy Flight 3 is in the middle of rolling out to SpaceX’s Kennedy Space Center Pad 39A launch facilities for a routine pre-launch static fire test, scheduled to occur no earlier than 12:30 pm ET (16:30 UTC), June 19th. If all goes well, SpaceX should be on track for its first STP-2 launch attempt at 11:30 pm ET (03:30 UTC), June 24th.

Anti-Tesla union leader ditches X, urges use of Threads instead

Tesla Sweden and IF Metall have been engaged in a bitter dispute for over two years now.

Marie Nilsson, chair of Sweden’s IF Metall union and a prominent critic of Tesla, has left X and is urging audiences to follow the union on Meta’s Threads instead.

Tesla Sweden and IF Metall have been engaged in a bitter dispute for over two years now. 

Anti-Tesla union leader exits X

In a comment to Dagens Arbete (DA), Nilsson noted that her exit from X is not formally tied to IF Metall’s long-running labor dispute with Tesla Sweden. Still, she stated that her departure is affected by changes to the platform under Elon Musk’s leadership.

“We have stayed because many journalists pick up news there. But as more and more people have left X, we have felt that the standard has now been reached on that platform,” she said.

Jesper Pettersson, press officer at IF Metall, highlighted that the union’s departure from X is only indirectly linked to Tesla Sweden and Elon Musk. “Indirectly it does, since there is a lot of evidence that his ownership has caused the change in the platform to be so significant. 

“We have nevertheless assessed that the platform had value for reaching journalists, politicians and other opinion leaders. But it is a microscopic proportion of the public and our members who are there, and now that value has decreased,” Petterson added.

IF Metall sees Threads as an X alternative

After leaving X, IF Metall has begun using Threads, Meta’s alternative to the social media platform. The union described the move as experimental, noting that it is still evaluating how effective the platform will be for outreach and visibility.

Pettersson acknowledged that Meta also does not operate under Sweden’s collective bargaining model, but said the union sees little alternative if it wants to remain visible online.

“In a perfect world, all large international companies would be supporters of the Swedish model when they come here. But unfortunately, the reality is not like that. If we are to be visible at all in this social media world, we have to play by the rules of the game. The alternative would be to become completely invisible, and that would not benefit our members,” he said.

Elon Musk confirms SpaceX is not developing a phone

Published

Despite many recent rumors and various reports, Elon Musk confirmed today that SpaceX is not developing a phone based on Starlink, not once, but twice.

Today’s report from Reuters cited people familiar with the matter and stated internal discussions have seen SpaceX executives mulling the idea of building a mobile device that would connect directly to the Starlink satellite constellation.

Musk did state in late January that SpaceX developing a phone was “not out of the question at some point.” However, He also said it would have to be a major difference from current phones, and would be optimized “purely for running max performance/watt neural nets.”

While Musk said it was not out of the question “at some point,” that does not mean it is currently a project SpaceX is working on. The CEO reaffirmed this point twice on X this afternoon.

Musk said, “Reuters lies relentlessly,” in one post. In the next, he explicitly stated, “We are not developing a phone.”

Musk has basically always maintained that SpaceX has too many things going on, denying that a phone would be in the realm of upcoming projects. There are too many things in the works for Musk’s space exploration company, most notably the recent merger with xAI.

SpaceX officially acquires xAI, merging rockets with AI expertise

A Starlink phone would be an excellent idea, especially considering that SpaceX operates 9,500 satellites, serving over 9 million users worldwide. 650 of those satellites are dedicated to the company’s direct-to-device initiative, which provides cellular coverage on a global scale.

Nevertheless, there is the potential that the Starlink phone eventually become a project SpaceX works on. However, it is not currently in the scope of what the company needs to develop, so things are more focused on that as of right now.

Tesla adds notable improvement to Dashcam feature

Tesla has added a notable improvement to its Dashcam feature after complaints from owners have pushed the company to make a drastic change.

Perhaps one of the biggest frustrations that Tesla owners have communicated regarding the Dashcam feature is the lack of ability to retain any more than 60 minutes of driving footage before it is overwritten.

It does not matter what size USB jump drive is plugged into the vehicle. 60 minutes is all it will hold until new footage takes over the old. This can cause some issues, especially if you were saving an impressive clip of Full Self-Driving or an incident on the road, which could be lost if new footage was recorded.

This has now been changed, as Tesla has shown in the Release Notes for an upcoming Software Update in China. It will likely expand to the U.S. market in the coming weeks, and was first noticed by NotaTeslaApp.

The release notes state:

“Dashcam Dynamic Recording Duration – The dashcam dynamically adjusts the recording duration based on the available storage capacity of the connected USB drive. For example, with a 128 GB USB drive, the maximum recording duration is approximately 3 hours; with a 1 TB or larger USB drive, it can reach up to 24 hours. This ensures that as much video as possible is retained for review before it gets overwritten.”

Tesla Adds Dynamic Recording

Instead of having a 60-minute cap, the new system will now go off the memory in the USB drive. This means with:

  • 128 GB Jump Drive – Up to Three Hours of Rolling Footage
  • 1TB Jump Drive – Up to 24 Hours of Rolling Footage

This is dependent on the amount of storage available on the jump drive, meaning that if there are other things saved on it, it will take away from the amount of footage that can be retained.

While the feature is just now making its way to employees in China, it will likely be at least several weeks before it makes its way to the U.S., but owners should definitely expect it in the coming months.

It will be a welcome feature, especially as there will now be more customization to the number of clips and their duration that can be stored.
