SpaceX gets ready to fire up Falcon Heavy for the first time at Cape Canaveral
As it gradually nears a launch date sometime in late January or early February, SpaceX’s new super-heavy launch vehicle (SHLV) Falcon Heavy has weathered a number of schedule delays in preparation for a historic and crucial moment – its first static fire/test ignition that’s currently scheduled for Tuesday, January 16, beginning at 4pm EST (2100 GMT).
Those focused on the gritty details of SpaceX’s prelaunch procedures will have immediately noted how different Falcon Heavy’s operations are when compared with SpaceX’s workhorse rocket and Heavy’s progenitor, Falcon 9. For a typical launch of Falcon 9, the rocket and payload will normally arrive at the given launch pad around a month or so before the anticipated launch date. Next, the satellite payload is encapsulated inside Falcon 9’s payload fairing, typically two or so weeks before launch. Pad facilities would be thoroughly examined after the previous launch to remedy any wear and tear and ensure that it is in good working order ahead of the next mission. Approximately a week before launch, Falcon 9’s first and second stages are mated together inside the pad’s integration facilities, the pad’s Transport/Erector/Launcher (TEL) is rolled into the integration facilities, and the Falcon 9 booster and second stage (sans payload) are mounted onto the TEL. Finally, the TEL and rocket are rolled out to the launch pad for a brief 3-5 second static fire around 5-7 days before launch. After testing is completed, the TEL is rolled back to the integration facilities, the payload fairing and payload are attached to the rocket, and the whole stack is once more rolled back to the pad, ready for launch.

For a used booster, this is the sum total of the prelaunch procedures it will go through at the pad, after recovery and refurbishment. For all new boosters, however, SpaceX currently conducts a thorough slate of tests for all Merlin 1D and MVac (2nd stage) rocket engines, as well as both the integrated first and second stages at its McGregor, Texas facilities. These tests last far longer than those conducted at the launch pad, and typically run for the full length of a launch in order to better simulate the stresses flight hardware will end up experiencing. In other words, new Falcon 9 hardware always has to make it through hundreds of seconds of live firing and post-test analysis before finally being shipped to SpaceX’s launch facilities, where it conducts the aforementioned brief static fire at the pad.
A whole new bird of prey
To put it simply, Falcon Heavy is a whole different animal when it comes to prelaunch testing. Due to the rocket’s sheer size and power in its fully integrated state, McGregor simply does not have the capability to conduct the same tests it does with Falcon 9. While two of the first Heavy’s three first stage boosters are modified flight-proven Falcon 9s (from Thaicom-8 and CRS-9), the center core required a far more extensive suite of changes from a normal Falcon 9 in order to survive the added stresses it would experience during a Falcon Heavy launch. Although the full-up vehicle could not be tested in Texas with a full-length firing, each of its three first stages and upper stage went through the same tests as a normal Falcon 9. Before that, both side core and center core structural test articles (STA) went through a large amount of mechanical stress testing to verify that Falcon Heavy’s re-engineered design would be able to easily survive the stresses of launch and then some. In short, months and months of work have gone into the hardware that both preceded and makes up the Falcon Heavy rocket currently vertical and weeks from launch at Kennedy Space Center.
However, SpaceX has learned the hard way that simulation and partial physical testing can only go so far, and cannot be completely trusted when it comes to flying new hardware, as evidenced by the both Falcon 1 and the company’s several first attempts at recovering a Falcon 9 booster (intact, at least…). Even the best and most brilliant engineers and technicians can only do so much without testing the real thing in real conditions, something that can often result in unintended failures – especially the case with new technologies. Falcon Heavy is indeed a new technology to some extent or at least incorporates numerous new technologies that SpaceX has little to no operational experience with. These and relatively untried aspects include the simultaneous ignition and operation of twenty seven already powerful Merlin 1D engines, new stresses on the center booster during launch, a unique non-explosive side booster separation mechanism, the also near-simultaneous recovery of three first stages, and a second stage tasked with placing an unusual payload in the highest orbit SpaceX has yet to attempt.
Hence Elon Musk’s aggressive expectation maintenance over the last year or so, in which he spared no punches while imparting upon several audiences the likelihood that Falcon Heavy’s first launch would fail entirely, and maybe even destroy the launch pad. In reality, SpaceX is clearly doing everything in their power to ensure that the massive rocket’s first launch is a total success.

What’s next for Falcon Heavy?
Recent delays to the vehicle’s first static fire test at SpaceX’s Launch Complex 39A are strong examples of this cautious approach. While fans and outsiders alike may be nipping at the bit for the vehicle’s long-awaited inaugural static fire and launch, SpaceX clearly is laser-focused on very thoroughly testing the vehicle and is exerting great caution. After the first static fire attempt was delayed, reportedly due to a buggy launch clamp, SpaceX had nevertheless completed its first (presumably successful) wet dress rehearsal (WDR), which saw the vehicle prepared for launch with a full load of propellant and other miscellaneous fluids. After a brief period back horizontal at the pad, likely to repair whatever fault initially caused the delay, Falcon Heavy has been vertical at the pad for the last several days. Intriguingly, albeit unsurprisingly, tank venting was reported early Sunday by local observers. This indicates that SpaceX conducted at least one additional wet dress rehearsal with Falcon Heavy, likely both contributing to an additional delay of the replacement static fire date (Monday) and solidifying confidence in the new test date, Tuesday, January 16.
Compared with the results of the first WDR (a three-day delay), the one day delay that followed Sunday’s rehearsal is great news for what is effectively a mature launch vehicle prototype. SpaceX’s confidence is clearly growing, and while all delays of the static fire will likely push back the launch date at least as much, Falcon Heavy will almost certainly find itself days away from its inaugural liftoff sometime in very late January or February 2018.

Tesla FSD changed its mind mid-intersection, and it may have saved a life
Tesla shares dashcam footage of FSD Supervised stopping mid intersection to avoid a T-bone crash.
Tesla is putting another Full Self-Driving save in front of its 24.8 million followers on X.
On Tuesday morning, Tesla’s main account shared a dashcam clip with the caption “FSD Supervised preventing T-bone crash.” The footage came from an owner posting as TheNewGrid, who described what happened at a stop sign: “I looked at the car coming to the stop sign figured they would stop, my car went, then came to a stop mid intersection as they flew by. Had I been manually driving this would have resulted in a crash.”
The sequence is the notable part. FSD had already started crossing when the other driver ran the stop sign. Instead of pressing on, the car braked hard in the middle of the intersection and let the crossing vehicle pass in front of it. By the owner’s own account, they had made the same assumption the software initially made, that the other car would stop, and would not have corrected in time.
FSD Supervised preventing T-bone crash

The clip is the latest in a run of safety posts Tesla has amplified over the past several days. On Saturday, the company shared a video from Selling Sunset star Jason Oppenheim, who sold his Bentley for a Model Y and said he was buying Teslas with FSD for 10 of his employees. Ashok Elluswamy, who leads Tesla AI, followed up by writing that Tesla self-driving “reacts to other people cutting into your path with super-human response times.” On Monday, a Cybertruck owner posted footage of FSD moving across three lanes from a red light to clear a path for an ambulance approaching from behind.
This recent clip also lands a few weeks after Tesla began shipping Automatic Collision Evasion with FSD v14.3.9, a feature that can activate FSD on the driver’s behalf when a frontal collision is imminent or the driver appears distracted. Elluswamy said in September that “even earlier prediction of hazards, even faster reaction time and overall significantly better safety and collision avoidance” are coming with v15, the release Tesla has tied to round the clock Robotaxi operation.
The safety messaging matters beyond social media. Tesla has said FSD Supervised was 4.1 times less likely to crash than manual driving across 100 million kilometers on European roads, and it has been putting those figures in front of regulators. Eight EU countries have now approved FSD Supervised, with Croatia the most recent, but the EU’s bloc-wide vote originally set for October 6 has been pushed to December at the earliest.
FSD Supervised is still a Level 2 system, and the driver remains responsible at all times. Even heavy users find reasons to step in. Teslarati’s Joey Klender, who uses FSD for about 76 percent of his driving, laid out five recurring issues on Tuesday that still prompt him to intervene. Clips like this one show the other column of that ledger: moments where the software caught a mistake a human was about to make.

Tesla Model 3 and Model Y can now do what only Cybertruck could
Tesla Model 3 and Model Y can power your home with Powerwall 3 during outages.
Tesla has turned its two top sellers into backup batteries for the house.
Tesla Energy announced on Tuesday that Powershare Home Backup is now available for new Model 3 and Model Y vehicles paired with a Powerwall 3, saying the car can “extend your home backup by over 2 days.” Minutes later, Tesla’s main account quoted the post with a broader pitch: “With Powerwall 3, every Tesla can now serve as your home’s backup battery.”
Until this week, the Cybertruck was the only Tesla that could send power back into a home, and that capability only began working alongside Powerwall 3 last month, after years of ambitious targets.
Tesla’s updated Powershare page says every Model 3 and Model Y ordered in the U.S. or Puerto Rico on or after October 1, 2026 can use the feature. Some, but not all, earlier cars also qualify. Owners can check on the touchscreen under Software, then Additional Vehicle Information, where a capable car shows “Powershare Support: Enabled.” As Electrek reported, bidirectional power on the two cars runs through an inverter Tesla calls PCS2 Lite, and the company has not said when that part entered production on each trim.
The home side is simpler. A house that already has a Powerwall 3 and either a Wall Connector 3 or Universal Wall Connector needs no additional equipment, and Tesla says compatibility is enabled through a software update. When the grid drops, the Powerwall and the car work together, with up to 11.52 kW of continuous power available. Tesla’s “over two days” estimate assumes a home using 30 kWh per day and a car starting at a 90 percent charge. Standard trims are rated for up to two days, while the Cybertruck adds more than three.
There are limits. Powerwall 2 and Powerwall+ support is listed as “coming soon.” Model S and Model X are not included, and Grid Support, the program that lets Cybertruck owners in Texas send power back to the grid during demand spikes for bill credits, is not available for Model 3 or Model Y.
The rollout also lines up with something Elon Musk said more than three years ago. At Tesla’s March 2023 Investor Day, Musk said, “I don’t think very many people are going to want to use bidirectional charging, unless you have a Powerwall.” Tesla has now shipped the feature for its volume cars with exactly that requirement attached.
The Powerwall pairing was the hard part on Cybertruck. Tesla told owners in December 2025 that Powershare with Powerwall had been pushed to mid 2026, and lead engineer Wes Morrill explained that two devices capable of forming a home’s grid have to negotiate which one leads during an outage, across multiple generations of hardware. With that work done for the truck, Tesla was able to extend it to the Model 3 and Model Y within a month.
Ford and GM have offered home backup from their EVs for several years, but both require a separate inverter and backup hardware. Tesla’s version leans on equipment many Powerwall 3 owners already have on the wall. Powershare for the two cars also ships as part of software update 2026.38.3, the same release that began delivering Halloween Mode on Tuesday.
Tesla is now starting to ship a “Halloween Mode” that is filled with some creepy and fun features; the company says, “This spooky update turns your Tesla into a haunted house on wheels.”
The update is just the latest in a series of updates that Tesla typically ships out in a seasonal fashion. The Spring and Summer Updates provided some fun novelty items while also packing some cool features that are actually useful for the ownership experience.
This one seems to be more fun-forward, and there are not any updates to the Full Self-Driving suite or overall operation of the vehicle. Instead, these novelty features are geared toward getting you in the mood for the Fall and Halloween.
