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.

The Federal Communications Commission (FCC) has accepted SpaceX’s filing for a new non-geostationary orbit (NGSO) satellite system of up to one million spacecraft and has opened the proposal for public comment. 

The move formally places SpaceX’s “Orbital Data Center” concept into the FCC’s review process, marking the first regulatory step for the ambitious space-based computing network.

FCC opens SpaceX’s proposal for comment

In a public notice, the FCC’s Space Bureau stated that it is accepting SpaceX’s application to deploy a new non-geostationary satellite system known as the “SpaceX Orbital Data Center system.” As per the filing, the system would consist of “up to one million satellites” operating at altitudes between 500 and 2,000 kilometers, using optical inter-satellite links for data transmission.

The FCC notice described the proposal as a long-term effort. SpaceX wrote that the system would represent the “first step towards becoming a Kardashev II-level civilization – one that can harness the Sun’s full power.” The satellites would rely heavily on high-bandwidth optical links and conduct telemetry, tracking, and command operations, with traffic routed through space-based laser networks before being sent to authorized ground stations.

FCC Chairman Brendan Carr highlighted the filing in a post on X, noting that the Commission is now seeking public comment on SpaceX’s proposal. Interested parties have until early March to submit comments.

What SpaceX is proposing to build

As per the FCC’s release, SpaceX’s orbital data center system would operate alongside its existing and planned Starlink constellations. The FCC notice noted that the proposed satellites may connect not only with others in the new system, but also with satellites in SpaceX’s first- and second-generation Starlink networks.

The filing also outlined several waiver requests, including exemptions from certain NGSO milestone and surety bond requirements, as well as flexibility in how orbital planes and communication beams are disclosed, as noted in a Benzinga report. SpaceX noted that these waivers are necessary to support the scale and architecture of the proposed system.

As noted in coverage of the filing, the proposal does not represent an immediate deployment plan, but rather a framework for future space-based computing infrastructure. SpaceX has discussed the idea of moving energy-intensive computing, such as AI workloads, into orbit, where continuous solar power and large physical scale could reduce constraints faced on Earth.

The Dubai Loop project is intended to improve passenger mobility in high-density urban areas through underground vehicle tunnels designed for faster construction and lower surface disruption than conventional transport systems.

Pilot route and project scope outlined

The first phase of the Dubai Loop will consist of a 4-mile (6.4 km) pilot route with four stations linking the Dubai International Financial Centre and Dubai Mall. The pilot phase is expected to pave the way for a full network extending up to 14 miles (22.5 km) with 19 stations connecting the Dubai World Trade Centre, the financial district, and Business Bay.

The tunnels will have a diameter of 12 feet (3.6 meters) and will be dedicated to vehicle transport. Construction will rely on tunneling methods designed to reduce costs and minimize disruption to existing infrastructure.

The pilot phase is estimated to cost about $154 million, with delivery expected roughly one year after design work and preparatory activities are completed. The full Dubai Loop network is projected to cost approximately $545 million and would take around three years to implement.

Tesla confirms Full Self-Driving still isn’t garnering interest from lagging competitors

Tesla executive Sendil Palani confirmed in a post on social media platform X that Full Self-Driving, despite being the most robust driver assistance program in the United States, still isn’t garnering any interest from lagging competitors.

Tesla has said on several occasions in the past that it has had discussions with a competing carmaker to license its Full Self-Driving suite. While it never confirmed which company it was, many pointed toward Ford as the one Tesla was holding dialogue with.

At the time, Ford CEO Jim Farley and Tesla CEO Elon Musk had a very cordial relationship.

Despite Tesla’s confirmation, which occurred during both the Q2 2023 and Q1 2024 Earnings Calls, no deal was ever reached. Whichever “major OEM” Tesla had talked to did not see the benefit. Even now, Tesla has not found that dance partner, despite leading every company in the U.S. in self-driving efforts by a considerable margin.

Elon Musk says Tesla Robotaxi launch will force companies to license Full Self-Driving

Palani seemed to confirm that Tesla still has not found any company that is remotely interested in licensing FSD, as he said on X that “despite our best efforts to share the technology,” the company has found that it “has not been proven to be easy.”

The question came just after one Tesla fan on X asked whether Tesla would continue manufacturing vehicles.

Because Tesla continues to expand its lineup of Model Y, it has plans to build the Cybercab, and there is still an immediate need for passenger vehicles, there is no question that the company plans to continue scaling its production.

However, Palani’s response is interesting, especially considering that it was in response to the question of whether Tesla would keep building cars.

Perhaps if Tesla could license Full Self-Driving to enough companies for the right price, it could simply sell the suite to car companies that are building vehicles, eliminating the need for Tesla to build its own.

While it seems like a reach because of Tesla’s considerable fan base, which is one of the most loyal in the automotive industry, the company could eventually bail on manufacturing and gain an incredible valuation by simply unlocking self-driving for other manufacturers.

The big question regarding why Tesla can’t find another company to license FSD is simply, “Why?”

Do they think they can solve it themselves? Do they not find FSD as valuable or effective? Many of these same companies didn’t bat an eye when Tesla started developing EVs, only to find themselves years behind. This could be a continuing trend.
