SpaceX launch technicians and engineers have officially completed the integration and static fire testing of the second Falcon Heavy rocket ever, nearing the end of preflight preparations for the vehicle’s critical commercial launch debut.
Carrying the commercial communications satellite Arabsat 6A, the rocket will be tasked with placing the massive spacecraft into a high-energy geostationary orbit. After a combination of hurdles and conflicting priorities conspired to delay Arabsat 6A’s launch from mid-2018 to February, March, and eventually, April of 2019, both the spacecraft and rocket are nearly ready to go. If all goes as planned, SpaceX will also complete the first successful launch and near-simultaneous landings of three independent rocket boosters, preparing two of the three boosters for reuse on a launch that could happen as early as June 2019.
When: 6:35 pm EDT, 22:35 UTC (click for your time), April 10th
What: Arabsat 6A, communications satellite, ~6000 kg (13,200 lb)

Falcon 9 Block 5, meet Falcon Heavy
- With this Falcon Heavy, SpaceX has effectively built – once again – a center stage that is nearly its own rocket, much like the tortured development of the first vehicle’s center stage can be blamed for a lot of its years of delays.
- Based on Falcon 9 V1.2’s Block 3 iteration, Falcon Heavy Flight 1’s center core was effectively outdated a year before it launched, and Falcon 9 Block 5 debuted just three months after its first and last launch.
- Combined with the center core’s untimely demise when it crashed into the Atlantic after running out of engine starter, the now 14 months separating Flight 1 and Flight 2 of Falcon Heavy can be explained by the rocket’s delayed path to the launch site.
- By the time the first Falcon Heavy’s main components were all present in at the launch site, SpaceX was already building Block 5 rockets and was as few as three months away from completely transitioning its Hawthorne, CA factory to Block 5.
- Due to the extensive changes in production incorporated into Block 5, this was effectively a no-turning-back deal where the cost of transitioning back was simply a non-starter.
- By the time Falcon Heavy had launched, and its center core had smashed itself to pieces on the Atlantic Ocean surface, it was far too late to begin producing a replacement copy. One step further, the process of ramping up Block 5 production had been slowed significantly by the drastic changes made across the board, taking SpaceX to the edge of production-related launch delays over the course of 2018.
- Put simply, building two side boosters and a relatively boutique Falcon Heavy center core – all three of which would be inextricably tied together for the foreseeable future – was not a practical option when three separate Falcon 9 Block 5 boosters could instead support 6-12+ launches over a period of six or so months.
(Hopefully) the first of many
- In the nominal event that SpaceX’s second Falcon Heavy launch is an unqualified success, it’s entirely possible that the doors to new markets could be opened as the world and its many spacefaring customers begin to contemplate the existence of an affordable super-heavy-lift launch vehicle – the first of its kind.
- On the outside, Falcon Heavy can begin to look like a bit of a boondoggle from a business perspective. It will have probably cost no less than $750M-$1B to develop, including the Block 5 modifications needed, and likely brought in less than $100M in gross revenue. It’s a black hole that SpaceX currently dumps huge volumes of cash into, in other words.
- However, this sort of observation is far too pessimistic and gives SpaceX far too little credit after some additional careful analysis. As of today, SpaceX has six public launch contracts for FH, two of which are from the USAF/NRO and likely valued around $130M-$150M.
- Purely commercial contracts for Falcon Heavy will probably be closer to $90M-100M, more than competitive with rockets like Atlas 5, Delta IV Heavy, Ariane 5, and other future vehicles like ULA’s Vulcan.
- Within ~12 months, the USAF will likely have awarded 10-16 additional launch contracts to some combo of Falcon 9 and Falcon Heavy as part of the latest EELV (now NSSL) acquisition phase. Assuming SpaceX is one of the two providers chosen, Falcon Heavy could receive numerous additional contracts for heavy military satellites.
- Additionally, NASA is now seriously considering Falcon Heavy for the launch of flagship missions like Europa Clipper and (maybe, maybe not) even Orion missions to the Moon.
- Falcon Heavy could also be the only vehicle in the world with the performance needed for a number of other missions that could arise from the Lunar Gateway, including launching actual segments of the space station and launching deep space cargo missions resupply said Gateway.
- Only ULA’s Delta IV Heavy can marginally compete with Falcon Heavy’s performance, but it typically costs no less than $300M per launch, a 2-3X surcharge over SpaceX’s offering. Due to the utter and complete lack of competition from both a price and performance perspective, SpaceX could essentially have the heavy life market cornered for something like 48-60+ months.
- Offering a unique product with potentially high demand and no real alternative, SpaceX would not be out of place to raise its profit margins significantly, helping to rapidly pay back the capital investment it put into Falcon Heavy’s extended development.
- Regardless, the future of Falcon Heavy has every right to be even more thrilling and diverse than the already impressive Falcon 9.
You can watch Falcon Heavy’s commercial launch debut live here on April 10th at 6:35 pm EDT (22:35 UTC). We’ll see you after the launch at LandingZone with exclusive photos and on-the-ground details of Falcon Heavy’s center core recovery.

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.
