SpaceX’s most important Falcon 9 booster yet returns to port with a lean
On November 19th, what is likely SpaceX’s most important Falcon 9 booster yet returned to Port Canaveral with a surprise – perhaps the most dramatic lean ever observed on one of the recovered rockets.
Tilted a solid 10+ degrees from vertical, the lean was immediately visible as soon as the top of the rocket crest the horizon, and it later became clear that one of Falcon 9 booster B1061’s four landing legs had no contact at all with drone ship Just Read The Instruction’s (JRTI) deck. Four days prior, Falcon 9 (and B1061) became the first commercially-developed rocket in history to be certified to launch NASA astronauts, a feat it pulled off flawlessly. Crew Dragon safely delivered four astronauts to the International Space Station on November 16th, marking the culmination of more than half a decade of (mostly) uninterrupted work.
Even before Crew Dragon and Falcon 9’s momentous Crew-1 launch, though, NASA had already revealed some details that would make parts of Crew-1 even more important and the follow-up Crew-2 launch – scheduled as early as March 2021 – perhaps the most significant mission in SpaceX’s history.
In short, less than a month after SpaceX’s equally flawless Crew Dragon Demo-2 astronaut launch debut, NASA contract modifications revealed that the agency had permitted SpaceX to reuse both Dragon capsules and Falcon 9 boosters on upcoming astronaut launches.
“In a wholly unexpected turn of events, a modification to SpaceX’s ~$3.1 billion NASA Commercial Crew Program (CCP) contract was spotted on June 3rd. Without leaving much room for interpretation, the contract tweak states that SpaceX is now “[allowed to reuse] the Falcon 9 launch vehicle and Crew Dragon spacecraft beginning with” its second operational astronaut launch, known as Post Certification Mission-2 (PCM-2) or Crew-2.”

A few short months after that discovery, NASA itself specifically announced that it had given SpaceX the go-ahead to reuse Demo-2 Crew Dragon capsule C206 and Crew-1 Falcon 9 booster B1061 on Crew-2, the company’s second operational astronaut launch. Scheduled no earlier than March 31st, 2021, Crew-2 will most likely launch before the Crew-1 Crew Dragon departs the space station and returns its four crew members to Earth, a milestone expected sometime in April.
For almost anyone who has followed NASA’s Commercial Crew Program (CCP) and its attitude towards SpaceX’s reusability efforts from the beginning, the space agency’s rapid willingness to trust its most important cargo – humans – to flight-proven Dragons and Falcon 9 boosters came as a huge surprise. If SpaceX is able to reuse both capsule C206 and booster B1061 as planned, Crew-2 will without a doubt be the most significant milestone in commercial spaceflight history, simultaneously proving that astronauts can be safely launched on commercial flight-proven rockets and spacecraft.
Of course, while Demo-2 Crew Dragon capsule C206 may have already been successfully recovered, SpaceX still had to land Falcon 9 booster B1061 and safely return it to port after Crew-1 before it could consider reusing it on Crew-2. Based on the rocket’s appearance upon its arrival at Port Canaveral, B1061 had an extremely close call. With what can be intuited from observation alone, it appears that sometime after B1061 landed and before the drone ship’s tank-like ‘Octagrabber’ robot could secure the booster, a stray swell or sudden burst of high seas must have bucked Just Read The Instructions about, causing B1061 to slide around on the slippery deck.
That would explain why the Falcon 9 first stage arrived in port on one of the far corners of drone ship JRTI – also sign that B1061 likely hit the yellow barrier included specifically to prevent boosters from sliding off drone ship decks. At the same time, B1061 must have had a moderately rough landing, causing at least one of its four legs to expend a large portion of a single-use shock absorber called a “crush core,” leaving the booster sitting at an angle. Based on photos of the arrival, that tilt likely left JRTI’s Octagrabber unable to latch onto all four of Falcon 9’s hold-down clamps, forcing recovery technicians to improvise and manually chain the rocket to the deck where the robotic solution fell short.
Thankfully, the SpaceX recovery team’s apparent heroics and luck proved to be enough and the sturdy Falcon 9 booster was returned to dry land without issue, lifted off of JRTI’s deck around 24 hours after arriving in port. Based on photos of the crush cores at the bottom tip of each leg, B1061’s rough landing and eventful journey was fairly mild as far as they come and, as CEO Elon Musk notes, crush core replacement is likely all that’s needed to make the rocket good as new.
Had B1061 been lost at sea, Crew-2 would have almost certainly been delayed to give SpaceX enough time to come up with an entirely new Falcon 9 first stage. Luckily for SpaceX, that didn’t happen and the company’s plans to launch astronauts on the flight-proven booster are still in play.

Tesla is using a redesigned Cybertruck battery cell to mitigate Semi challenges
It is perhaps the most recent example of Tesla using unique engineering prowess and cross-pollinating vehicle elements to solve common problems, something it does better than most companies out there.
Tesla revealed that it is utilizing redesigned Cybertruck battery cells in its Long Range Semi to mitigate some pertinent challenges that come with long-haul logistics.
It is perhaps the most recent example of Tesla using unique engineering prowess and cross-pollinating vehicle elements to solve common problems, something it does better than most companies out there.
Tesla’s long-awaited Semi truck is entering production at its Nevada Gigafactory, and fresh factory footage reveals a clever evolution in its battery technology.
The Long Range variant, designed for up to 500 miles of real-world range, relies on a structural battery pack that uses the same 4680-form-factor cells found in the Cybertruck.
However, Tesla engineers have completely redesigned the pack’s architecture—shifting from the flat, pancake-style modules typical in passenger vehicles to a compact, vertical cubic layout. This change isn’t just about cramming more energy into the chassis; it’s a targeted solution to one of electric trucking’s biggest headaches: range loss in cold climates.
Dan Priestley, Head of the Tesla Semi program, said:
“We’re using essentially the same cell out of Cybertruck, but our cars packs are more like a pancake. Whereas these are more like a cube. You get a lot of energy stored in a small space. You can only do this if you design the vehicle to be electric from the ground up.”
Here, in all its glory, is the exclusive first look at the massive @Tesla Semi factory.

In conventional EVs, battery packs are laid out horizontally in wide, flat arrays to fit under the floor. While this works for cars and even the Cybertruck’s structural pack, it exposes a large surface area to the elements.
Heat escapes quickly, especially overnight when the truck is parked. Cold temperatures slow chemical reactions inside lithium-ion cells, reducing available energy and forcing the vehicle to expend extra power warming the battery and cabin.
Real-world tests on vehicles like the Cybertruck show winter range losses of 20-40 percent, depending on conditions. For long-haul truck drivers operating in Canada, Scandinavia, or the northern U.S., this “silent killer” means unplanned stops, reduced payloads, and higher operating costs.
From personal experience, cold weather still impacts EV batteries even with various inventions and strategies that companies have come up with. In the cold Pennsylvania winter, charging was much more frequent for me due to range loss due to temperatures.
Tesla’s cubic battery pack flips the script. By arranging the 4680 cells in tall, dense vertical stacks, the pack minimizes external surface area relative to its volume—essentially turning the battery into its own thermal blanket.
Factory video from the Semi assembly line shows these large, yellow-green structural modules mounted directly onto the chassis, forming a near-cube shape.
The reduced exposure helps the pack retain heat generated during operation, keeping cells closer to their optimal temperature even after hours in sub-zero conditions.
The design doesn’t stop there. Tesla pairs the cubic pack with an advanced heat pump system that actively recycles thermal energy from the motors, brakes, and even ambient air.

Unlike passive systems in earlier EVs, this architecture transfers waste heat back into the battery, maintaining readiness for morning departures without draining the pack.
Executives have noted that the combination, cubic geometry plus intelligent thermal management, dramatically cuts overnight cooldown and range degradation, making the Semi viable for 24/7 fleet operations in harsh winters.
Beyond cold-weather performance, the redesigned pack integrates structurally with the truck’s frame, enhancing rigidity while simplifying assembly. Production footage shows workers installing the massive modules early in the line, signaling that the Semi’s battery is now a core chassis component rather than an add-on.
Using proven 4680 cells keeps costs down and leverages Tesla’s scaled manufacturing know-how from Cybertruck and Model Y lines.
Tesla’s focus on ramping up Semi output will lean on small innovative steps like this one. Truckers are not immune to traveling in cold weather conditions, and changes like this one will help make them more effective while also increasing output by logistics operators who choose to go all-electric with the Tesla Semi.

SpaceX is keeping the Space Station alive again this weekend
SpaceX’s Falcon 9 launches Northrop Grumman’s Cygnus NG-24 to the ISS with 11,000 pounds of cargo Saturday.
SpaceX is targeting April 11 for the launch of Northrop Grumman’s Cygnus XL cargo spacecraft to the International Space Station, carrying over 11,000 pounds of supplies, science hardware, and equipment for the Expedition 73 crew aboard. Liftoff is set for 7:41 a.m. ET from Space Launch Complex 40 at Cape Canaveral Space Force Station, with a backup window available April 12 at 7:18 a.m. ET.
The mission, officially designated NG-24 under NASA’s Commercial Resupply Services program, names its spacecraft the S.S. Steven R. Nagel in honor of the NASA astronaut who flew four Space Shuttle missions and logged over 723 hours in space before his death in 2014. Unlike SpaceX’s own Dragon capsule, which docks autonomously, Cygnus relies on NASA astronauts to capture it using a robotic arm before it is berthed to the space station’s module for unloading. When the mission wraps up around October, the Cygnus will depart loaded with station trash and burn up on reentry.
Countdown: America is going back to the Moon and SpaceX holds the key to what comes after
This is the second flight of the Cygnus XL configuration, which debuted on NG-23 in September 2025 and offers a roughly 20% increase in cargo capacity over the previous design. Northrop Grumman switched to Falcon 9 launches after its own Antares 230+ rocket was retired in 2023 following supply chain disruptions from the war in Ukraine.
The upcoming cargo includes a new module to advance quantum research, and an investigation studying blood stem cell production in microgravity with potential therapeutic applications on Earth.
The NG-24 mission is one piece of a much larger picture for SpaceX and the U.S. government. As Teslarati reported, SpaceX has become an indispensable launch provider for U.S. national security missions, picking up a $178.5 million Space Force contract in April 2026 to launch missile tracking satellites, while also holding roughly $4 billion in NASA contracts tied to the Artemis lunar program.
At a time when no other American rocket can match the Falcon 9’s combination of reliability, cost, and launch cadence, Saturday’s mission is a straightforward reminder of how much the U.S. government now depends on a single commercial provider to keep its astronauts supplied and its satellites flying.

Tesla hits FSD hackers with surprise move
In recent weeks, the company has begun remotely disabling FSD capabilities on affected vehicles, and in some instances, permanently revoking access even for owners who paid thousands of dollars for the feature.
Tesla is cracking down on hackers who have figured out a way to utilize third-party programs to activate Full Self-Driving (FSD) in their vehicles — despite the suite not being approved for use in their country.
Tesla has launched a sweeping enforcement campaign against owners using third-party hardware hacks to activate FSD software in countries where the advanced driver-assistance system remains unregulated or unapproved.
In recent weeks, the company has begun remotely disabling FSD capabilities on affected vehicles, and in some instances, permanently revoking access even for owners who paid thousands of dollars for the feature.
Tesla has started remotely disabling Full Self-Driving on cars fitted with third-party CAN bus hacks in countries where the software is not yet approved.
This crackdown began after the hacks started spreading widely last month. 👇 pic.twitter.com/wL8VqZuTlK

Reports of the crackdown have surfaced across Europe, China, Japan, South Korea, and the UK, marking a significant escalation in Tesla’s efforts to enforce regional software restrictions.
FSD is Tesla’s flagship supervised autonomy package, which is available in several countries across the world. Currently limited by regulatory hurdles, it has not received full approval in most markets outside of the United States due to various things, such as safety standards, data privacy, and local traffic laws.
However, the company is working to expand its availability globally. Nevertheless, Tesla has installed the necessary hardware on vehicles globally, but locks the features based on geographic location.
Some owners have taken accessing FSD into their own hands, using jailbreak or bypass devices.
These “jailbreak” tools, typically €500 USB-style modules that plug into the vehicle’s Controller Area Network (CAN) bus, intercept signals to spoof approvals and unlock FSD, including advanced navigation, Autopark, and Summon features.
Hackers in Poland, Ukraine, and elsewhere have distributed the devices, with some claiming they work on HW3 and HW4 vehicles and can be unplugged to restore stock settings. In China alone, over 100,000 owners reportedly installed such modifications.
Tesla’s response has been swift and uncompromising. Recently, the company began sending in-car notifications and emails warning owners that unauthorized modifications violate terms of service, compromise vehicle safety systems, and expose cars to cybersecurity risks.
The email communication read:
“Your vehicle has detected an unauthorized third-party device. As a precaution, some driver assistance functions have been disabled for safety reasons. A software update will be available soon. Once you install the update, some features may be enabled again.”
Vehicles detected using the hacks have had FSD capabilities remotely disabled without refund. In some cases, owners report permanent bans, even if they had legitimately purchased the software package.
Tesla’s hardline stance underscores its commitment to regulatory compliance and safety.
Tesla has long argued that unsupervised FSD requires rigorous validation, and premature activation could endanger drivers and bystanders.
The crackdown sends a clear-cut message to those who are bypassing the FSD safeguards, but there are greater implications for Tesla if something were to go wrong. This is an understandable way to protect the company’s reputation for its FSD suite.
