SpaceX Falcon Heavy side booster arrives at Texas test facilities
NASASpaceflight.com reports that the first new booster for SpaceX’s next Falcon Heavy launch has arrived at the company’s McGregor, Texas test facilities.
The canonical sign that SpaceX is rapidly progressing towards its next Falcon Heavy launch, the mission – set to carry the US military’s US Space Force 44 (USSF-44) satellite(s) directly to geostationary orbit (GEO) – requires all new boosters. For SpaceX, barring a major surprise in the next five months, USSF-44 will be the first operational direct-to-GEO launch in the company’s history – a milestone years and multiple test flights in the making.
US military officials have begun to at least vaguely support the idea of flying payloads on flight-proven SpaceX rockets but it looks to be a long uphill battle ahead of the company. It took almost half a decade and four-dozen successful booster landings for the US Air Force to even allow SpaceX to attempt to land a Falcon 9 booster after an operational military launch. As a result, the company will likely be building new rockets for its military launches for the indefinite future – Falcon Heavy and its three boosters included.
The photo at the top of this article shows a largely identical Falcon Heavy Block 5 side booster – either B1052 or B1053 – during a late-2018 static fire acceptance test campaign in McGregor, Texas.
Based on NASASpaceflight.com’s aerial photos of the latest rocket to arrive in McGregor, Texas, one would assume that SpaceX was simply testing a new Falcon 9 first stage. Notably, the booster appears to have a Falcon 9 interstage installed, whereas Falcon Heavy side boosters have historically been tested with nosecones installed. However, by analyzing the layout of decals visible on its exterior, author Thomas Burghardt discovered that the booster – believed to be B1064 – is likely the first of two new Falcon Heavy side boosters needed for USSF-44.
For unknown reasons, SpaceX has outfitted, transported, and prepared B1064 for acceptance testing with a years-old interstage installed, effectively making it a Falcon Heavy side booster in Falcon 9 clothing (sans nosecone).

In its current configuration, the process of manufacturing three new Falcon Heavy boosters at SpaceX’s Hawthorne, CA factory takes at least half a year from the start of tank welding to shipment. After each booster is completed, it must ship to McGregor, Texas for at least 4-6 weeks to undergo acceptance tests, including at least one wet dress rehearsal (WDR) and static fire. In other words, if the first of three new Falcon Heavy Block 5 boosters has just arrived in McGregor, SpaceX likely has two or three months of work to go before the entire USSF-44 rocket is on site at Florida’s Kennedy Space Center.
Just two weeks ago, a US military official revealed that SpaceX’s USSF-44 Falcon Heavy launch date had slipped from late-2020 (likely November or December) to no earlier than (NET) February 28th, 2021. The cause of the delay is unknown but either way, it should give SpaceX two full months to process Falcon Heavy Flight 4 hardware in Florida (or several weeks of margin wherever needed). After USSF-44, SpaceX’s next Falcon Heavy launch – USSF-52; also expected to fly on all-new boosters – was scheduled to launch NET “early 2021” before the preceding mission’s delay was announced. To achieve that schedule, SpaceX will likely be building and testing new Falcon Heavy boosters – and Falcon Heavy boosters only – from mid-2020 to at least Q1 2021.

On the plus side, as NASASpaceflight.com noted, if SpaceX manages to recover all USSF-44 and USSF-52 boosters, it will quickly find itself with a fleet of six side boosters and two center cores.

Tesla rolls out new Supercharging safety feature in the U.S.
Tesla has rolled out a new Supercharging safety feature in the United States, one that will answer concerns that some owners may have if they need to leave in a pinch.
It is also a suitable alternative for non-Tesla chargers, like third-party options that feature J1772 or CCS to NACS adapters.
The feature has been available in Europe for some time, but it is now rolling out to Model 3 and Model Y owners in the U.S.
With Software Update 2026.2.3, Tesla is launching the Unlatching Charge Cable function, which will now utilize the left rear door handle to release the charging cable from the port. The release notes state:
“Charging can now be stopped and the charge cable released by pulling and holding the rear left door handle for three seconds, provided the vehicle is unlocked, and a recognized key is nearby. This is especially useful when the charge cable doesn’t have an unlatch button. You can still release the cable using the vehicle touchscreen or the Tesla app.”
The feature was first spotted by Not a Tesla App.
This is an especially nice feature for those who commonly charge at third-party locations that utilize plugs that are not NACS, which is the Tesla standard.
For example, after plugging into a J1772 charger, you will still be required to unlock the port through the touchscreen, which is a minor inconvenience, but an inconvenience nonetheless.
Additionally, it could be viewed as a safety feature, especially if you’re in need of unlocking the charger from your car in a pinch. Simply holding open the handle on the rear driver’s door will now unhatch the port from the car, allowing you to pull it out and place it back in its housing.
This feature is currently only available on the Model 3 and Model Y, so Model S, Model X, and Cybertruck owners will have to wait for a different solution to this particular feature.

LG Energy Solution pursuing battery deal for Tesla Optimus, other humanoid robots: report
Optimus is expected to be one of Tesla’s most ambitious projects, with Elon Musk estimating that the humanoid robot could be the company’s most important product.
A recent report has suggested that LG Energy Solution is in discussions to supply batteries for Tesla’s Optimus humanoid robot.
Optimus is expected to be one of Tesla’s most ambitious projects, with Elon Musk estimating that the humanoid robot could be the company’s most important product.
Humanoid robot battery deals
LG Energy Solution shares jumped more than 11% on the 28th after a report from the Korea Economic Daily claimed that the company is pursuing battery supply and joint development agreements with several humanoid robot makers. These reportedly include Tesla, which is developing Optimus, as well as multiple Chinese robotics companies.
China is already home to several leading battery manufacturers, such as CATL and BYD, making the robot makers’ reported interest in LG Energy Solution quite interesting. Market participants interpreted the reported outreach as a signal that performance requirements for humanoid robots may favor battery chemistries developed by companies like LG.
LF Energy Solution vs rivals
According to the report, energy density is believed to be the primary reason humanoid robot developers are evaluating LG Energy Solution’s batteries. Unlike electric vehicles, humanoid robots have significantly less space available for battery packs while requiring substantial power to operate dozens of joint motors and onboard artificial intelligence processors.
LG Energy Solution’s ternary lithium batteries offer higher energy density compared with rivals’ lithium iron phosphate (LFP) batteries, which are widely used by Chinese EV manufacturers. That advantage could prove critical for humanoid robots, where runtime, weight, and compact packaging are key design constraints.

Tesla receives approval for FSD Supervised tests in Sweden
Tesla confirmed that it has been granted permission to test FSD Supervised vehicles across Sweden in a press release.
Tesla has received regulatory approval to begin tests of its Full Self-Driving Supervised system on public roads in Sweden, a notable step in the company’s efforts to secure FSD approval for the wider European market.
FSD Supervised testing in Sweden
Tesla confirmed that it has been granted permission to test FSD Supervised vehicles across Sweden following cooperation with national authorities and local municipalities. The approval covers the Swedish Transport Administration’s entire road network, as well as urban and highways in the Municipality of Nacka.
Tesla shared some insights into its recent FSD approvals in a press release. “The approval shows that cooperation between authorities, municipalities and businesses enables technological leaps and Nacka Municipality is the first to become part of the transport system of the future. The fact that the driving of the future is also being tested on Swedish roads is an important step in the development towards autonomy in real everyday traffic,” the company noted.
With approval secured for FSD tests, Tesla can now evaluate the system’s performance in diverse environments, including dense urban areas and high-speed roadways across Sweden, as noted in a report from Allt Om Elbil. Tesla highlighted that the continued development of advanced driver assistance systems is expected to pave the way for improved traffic safety, increased accessibility, and lower emissions, particularly in populated city centers.
Tesla FSD Supervised Europe rollout
FSD Supervised is already available to drivers in several global markets, including Australia, Canada, China, Mexico, New Zealand, and the United States. The system is capable of handling city and highway driving tasks such as steering, acceleration, braking, and lane changes, though it still requires drivers to supervise the vehicle’s operations.
Tesla has stated that FSD Supervised has accumulated extensive driving data from its existing markets. In Europe, however, deployment remains subject to regulatory approval, with Tesla currently awaiting clearance from relevant authorities.
The company reiterated that it expects to start rolling out FSD Supervised to European customers in early 2026, pending approvals. It would then be unsurprising if the company secures approvals for FSD tests in other European territories in the coming months.
