SpaceX drone ship dodges high seas en route to first rocket landing of 2020

Published

on

SpaceX has delayed the first orbital launch of the new year by a handful of days to allow both Falcon 9 and the drone ship it’s scheduled to land on the opportunity to dodge bad weather on the Florida coast and out in the Atlantic Ocean.

Originally scheduled to launch no earlier than December 30th, SpaceX delayed its next mission – Starlink-2 – to January 3rd for unknown reasons. Weather on the new date was unfortunately forecast to be terrible at SpaceX’s LC-40 launch pad and had a 60% chance of scrubbing the mission. SpaceX must have been at least as concerned about conditions for drone ship Of Course I Still Love You (OCISLY) in the Atlantic Ocean, as the company ultimately skipped over a 90%-GO backup window on January 4th for the latest launch target – January 6th.

Historically, only a few Falcon launches have been delayed for booster recovery purposes, but it’s been apparent that – while incredibly sturdy – some of the tacked-on equipment installed on SpaceX’s drone ships (modified barges) can be easily damaged by high seas. Perhaps more importantly, high seas (and thus a pitching drone ship deck) can make booster landings much riskier. Bad luck could easily cause a booster to cut off its landing burn at exactly sea level but still be a dozen or more feet above the drone ship’s deck if it’s coincidentally in the trough of a big swell, potentially destroying or damaging the rocket.

Ultimately, on missions where SpaceX has nothing to lose by delaying the launch, the company now puts a successful booster recovery much higher on its list of priorities. As recently as March 2018, SpaceX intentionally expended a new Falcon 9 booster because ocean conditions would have been extremely risky to OCISLY and crew and the company (or customer) had no interest in delaying the launch further to wait for calmer seas.

By all appearances, that is – for the most part – no longer the case. SpaceX would likely expend a rocket for a few days of schedule for high-priority customers like the USAF and especially NASA, where even a few days of delays could trigger several years of delays to quite literally wait for the planets to realign. It has and will continue to require a significant culture shift in the market for launch but SpaceX is clearly changing those norms and expectations bit by bit, to the point that the company was recently willing to delay Cargo Dragon launches for NASA to ensure that the mission’s Falcon 9 booster the best possible chance of recovery.

For an internal Starlink launch, delaying the mission to prevent drone ship damage and ensure Falcon 9 recovery is thus an absolute no-brainer. Starlink-2 is also partially unique because it will mark the second time a Falcon 9 booster launches for the fourth time, following on the footsteps of B1048 after it became the first booster to launch four times during SpaceX’s November 2019 Starlink-1 mission.

B1048 thus became SpaceX’s lone pathfinder for Falcon 9 booster reusability, hopefully providing excellent insight and some unequivocal physical data to determine the rocket’s health and readiness for a 5th launch. Still, even though the sample sizes available to even the most prolific orbital launch vehicles would make any statistician cringe, it’s safe to say that two data points are better than one, and B1049 – scheduled to launch for the fourth time on Starlink-2 – would thus be quite valuable to SpaceX’s recovery engineers and technicians.

Only one additional Falcon 9 booster – B1056 – has already flown three missions, meaning that SpaceX will – at best – likely have to suffice with three data points (B1048, B1049, B1056) before moving onto the next reusability milestone – launching the same booster five times. Ultimately, every time SpaceX pushes that envelope and demonstrates that Falcon boosters can be definitively reused 3 or 4 or 5 times, the company multiplies the number of launches its fleet of booster can perform by a factor of two.

For, say, the eight flightworthy boosters in SpaceX’s existing fleet, proving that a 4th reuse is possible will ultimately allow the company to squeeze an additional seven launches from existing hardware with almost zero capital investment. For now, the fourth flight of Falcon 9 boosters will remain cutting edge, but with more than three-dozen launches planned in 2020, it’s all but guaranteed that SpaceX will push the envelope of reusability like never before in the coming months.

Tesla Roadster’s new patent preps white-knuckle speeds, keeping it grounded

Ahead of its highly anticipated unveiling, Tesla’s upcoming Roadster received a new patent that aims to keep it grounded while enabling white-knuckle speeds.

The patent, which was granted on September 29, is titled “Electric Car Fan,” bluntly stating its design but not its purpose, which is further detailed in the text of the application. Interestingly, it comes two weeks before the Roadster event, which was delayed due to unfavorable weather on Thursday, which could cause issues, as Tesla revealed the event must be held outdoors.

The purpose is to solve a problem that is relatively unique to high-performance electric cars. Instant motor torque is useless if the tires cannot plant that force, and conventional wings and underbody tunnels generate downforce only when air is already rushing past the car. At launch, in slow corners, and under hard braking from modest speed, passive aerodynamic additions contribute essentially very little to downforce.

Tesla’s filing says that its fans can produce the downforce needed, independent of vehicle velocity, then ease off so the same hardware does not pile on drag at highway speeds, an issue that can come from excessive body modifications.

The hardware outlined in the patent is a ducted-fan package that is placed into the rear of the vehicle. An underbody inlet between the rear wheels feeds a duct that rises to a wide outlet in the diffuser. In that outlet are four axial fans, which are divided by vertical strakes. They will pull air from under the floor and press the chassis onto the pavement.

The language in the patent claims it can cut drag rather than add to it while simultaneously increasing downforce.

Tesla Roadster event requires restricted airspace, and the FAA obliges

The fans run from the high-voltage battery and a vehicle control system, so output can be modulated rather than left on as a fixed penalty.

There are additional strengths that can come from this design, like extra tire load at low speed, which can contribute to even more face-melting acceleration rates, decrease stopping distance, and sharper turn-in before a wing has air to work with. Adjustable fan speed lets the car add grip only when needed, so it can be catered to the force of a turn or acceleration.

These designs were previously used, and banned, in some competitive settings. The Brabham BT46B was banned in F1 competition for using a similar fan design and being labeled as too effective.

Tesla still lists the Roadster as having a sub-two-second 0-60 MPH time and a 250-plus-MPH top speed, and there are expectations for a SpaceX cold-gas thruster package that could not only increase acceleration but potentially cause the vehicle to hover.

It is important to note that a patent is not a production part, and packaging four fans in a rear diffuser, managing noise, and potential debris are all things Tesla must consider. With that being said, the patent being granted shows Tesla is designing the Roadster to go fast, but it is also attempting to use unique strategies to combat any issues it might have at those speeds.

Tesla showrooms picked clean ahead of Q3 end as demand looks strong

Tesla (NASDAQ: TSLA) showrooms have been picked clean ahead of the end of the third quarter of the year, as demand looks to be strong and delivery estimates for new vehicles are pushed into late 2026 and early 2027.

Tesla appears to have sold out of many of its Model 3 and Model Y trim levels in the United States, as only the Model Y RWD and Model Y All-Wheel-Drive are available for delivery before the end of the year.

Additionally, many showrooms are either completely empty or void of all but just one demo unit within the buildings themselves in an effort to bolster what could be one of Tesla’s best quarters in vehicle deliveries in recent memory.

Additionally, when I spoke to the guys at Tesla Mechanicsburg two weeks ago, when I returned the Model Y L, their third hauler of the week had just arrived, and every vehicle on it, along with every vehicle in their delivery lot, was accounted for and had a name attached to it for delivery.

Tesla saw a 25 percent increase in deliveries in Q2 compared to the same quarter the year before. The vast majority of the 480,126 units it delivered, 467,762 vehicles to be exact, were the Model 3 and Model Y.

In Q3 2025, Tesla delivered 497,099 vehicles, once again a figure that was dominated by the company’s two mass-market vehicles. Analysts have unusually wide predictions for this quarter, likely because so many firms missed the Q2 delivery figure by such a substantial margin; Wall Street predicted 408,000 cars, while Tesla delivered 480,000.

Goldman Sachs has Tesla slotted for 435,000 deliveries in Q3, while JPMorgan said it anticipates 482,000. The median guess is about 449,000 deliveries for Q3.

Watch Tesla’s “guardian angel” FSD feature take over for collision evasion

Published

By

Tesla’s Automatic Collision Evasion feature can be seen in one of the first owner videos of it in action.

Tesla owner Spencer (@scotsrule08) posted on Monday that the feature “worked flawlessly,” saying FSD reengaged itself just as he was about to hit a curb. Ashok Elluswamy, who leads Tesla’s AI team, shared the clip and wrote, “A guardian angel always looking out for you.”

The video arrives in the middle of a staged rollout. Tesla first shipped Automatic Collision Evasion with FSD (Supervised) v14.3.9 in software update 2026.27.6 earlier this month, which Teslarati covered as it reached cars. Update 2026.27.10, which began going out on September 19, carried the feature improvements with FSD v14.3.10, according to release notes tracked by Not a Tesla App. The newer 2026.27.11 build is now reaching another wave of vehicles.


The feature only runs on HW4 vehicles, and it requires an active FSD purchase or subscription with both FSD (Supervised) and Automatic Emergency Braking enabled. HW3 owners receive FSD v14.2 Lite in the same updates, but that build does not include collision evasion.

Tesla’s release notes describe two triggers. The first is an imminent frontal collision that braking alone may not prevent, in which case the car can activate FSD to steer, brake or accelerate around the hazard. That scenario is limited to highways below 85 mph, with no pedestrians or cyclists detected and no slippery road surface. The second covers a driver who appears inattentive, such as reaching into the back seat, or who seems to have switched off FSD by accident. Spencer’s curb clip appears to fall into that second category.

Tesla plans big safety improvements for Full Self-Driving v15

Once the system takes over, the accelerator is muted and light brake input will not cancel the maneuver. Drivers need to apply firm, deliberate steering force to take back control, and the car chimes to hand control back once the danger has passed.

Elluswamy recently noted that earlier hazard prediction, faster reaction time and better collision avoidance would arrive with FSD v15, the next major version.
