SpaceX to test last old-gen Falcon 9’s orbital upper stage lifespan tonight
SpaceX Falcon 9 B1045 is just hours away from completing its second and final mission, a launch that will also signify a swan-song for the reusable rocket company’s Block 4 and older boosters. Not one to let an opportunity go to waste, Elon Musk’s space company intends to do a long coast demonstration of the orbital upper stage once the reused Cargo Dragon spacecraft separates.
Jessica Jensen, SpaceX’s Director of Dragon Mission Management, spoke among a panel of CRS-15 stakeholders on the morning of June 28 and spoke evident pride and confidence in the company’s progress up to this point, with respect to both the mission at hand and SpaceX’s achievements more generally. CRS-15, the third flight-proven Dragon and Falcon 9 launch, is a fitting mission for SpaceX to bring to a close their H1 launch manifest (the 12th of 2018), mainly due to the impressive fact that more than two-thirds of the boosters launched this year have been flight-proven.

As Jensen rightfully noted, SpaceX completed its first-ever reuse of a recovered Falcon 9 booster scarcely 15 months ago in March 2017, a period in which SpaceX has since completed 26 missions, recovered 16 Falcon 9 and Heavy boosters, and successfully launched 12 flight-proven rocket boosters. At the current rate of launch, SpaceX is likely to smash its previous annual cadence record – 18 in 2017 – with anywhere from 24 to 28 launches this year, with CRS-15 marking a dozen missions in the first half of the year, if successful. As such, simply the launch frequency in the first six months would bring SpaceX to 24 completed missions this year. A slight uptick, perhaps as a result of the rapid reusability of new Block 5 boosters, might allow SpaceX to squeeze in several additional missions.
Critically, Jensen also noted that B1045’s final launch will be significant for a reason other than the fact that it nearly halved the previous record for Falcon 9 booster refurbishment, an accomplishment she ceded to the skill and growing experience of SpaceX’s rocket refurbishment teams of engineers and technicians. Aside from that growing expertise, she stated that
“[CRS-15] will also be the final Block 4 configuration of a Falcon 9 booster that SpaceX flies, so all the boosters from here on out will be the Block 5 version.”
Barring unforeseen design flaws, Falcon 9 Block 5 has the potential to be a game-changer, perhaps allowing SpaceX to finally realize a long-term goal of dramatically lowering the cost of access to orbit with new reliable, reusable rockets. Reported by NASASpaceflight.com to be flying aboard a Block 4 booster, something also confirmed to Teslarati through a separate source, it’s not 100% clear if Jensen’s blanket statement included the upcoming in-flight Crew Dragon abort test, scheduled sometime after the upgraded Dragon’s first launch in late 2018. Regardless, she is fully correct in the sense that all future commercial SpaceX launches after CRS-15 will quite definitively fly aboard Falcon 9 and Heavy Block 5 rockets.

Flight-proven Cargo Dragons a new norm for SpaceX
Meanwhile, the specifics of CRS-15 mirror SpaceX’s two most recent International Space Station resupply missions, both of which simultaneously flew flight-proven orbital Cargo Dragon spacecraft and flight-proven Falcon 9 boosters, leaving just the second stage and Cargo Dragon trunk to be expended. As a taste of the future SpaceX fully intends to realize, the spectacle of these CRS missions is not only undeniable but demonstrates a newfound confidence in commercial reusable rockets growing within NASA, an agency that SpaceX would quite simply not be here today without.

After CRS-15, SpaceX has another five flight-proven Cargo Dragon missions left on their CRS-1 contract, after which the updated CRS-2 contract will take over, replacing the old Cargo Dragon with an upgraded cargo version of SpaceX Crew Dragon, also known as Dragon 2. CRS-2 launches are currently scheduled to begin sometime in 2020.
Finally, reminiscent of Falcon Heavy’s spectacular debut launch, Falcon 9’s upper stage “will be doing a long coast demonstration [after Cargo Dragon separates from the rocket]”. Jensen was unable to go into more detail here, but it can be safely presumed that the S2 coast test is either related testing for upper stage reusability or is being used as an opportunity to further demonstrate on-orbit coast capabilities to the US Air Force and/or NASA, a feature that is necessary for certain national security and interplanetary missions.

Tesla CEO Elon Musk teases insane capabilities of next major FSD update
Tesla CEO Elon Musk teased the insane capabilities of the next major Full Self-Driving update just hours after the company rolled out version 14.2 to owners.
Tesla Full Self-Driving v14.2 had some major improvements from the previous iteration of v14.1.x. We were on v14.1.7, the most advanced configuration of the v14.1 family, before Tesla transitioned us and others to v14.2.
However, Musk has said that the improvements coming in the next major update, which will be v14.3, will be where “the last big piece of the puzzle finally lands.”
14.3 is where the last big piece of the puzzle finally lands
— Elon Musk (@elonmusk) November 21, 2025
There were some major improvements with v14.2, most notably, Tesla seemed to narrow in on the triggers that caused issues with hesitation and brake stabbing in v14.1.x.
One of the most discussed issues with the past rollout was that of brake stabbing, where the vehicle would contemplate proceeding with a route as traffic was coming from other directions.
We experienced it most frequently at intersections, especially four-way stop signs.
Elon Musk hints at when Tesla can fix this FSD complaint with v14
In our review of it yesterday, it was evident that this issue had been resolved, at least to the extent that we had no issues with it in a 62-minute drive, which you can watch here.
Some owners also reported a more relaxed driver monitoring system, which is something Tesla said it was working on as it hopes to allow drivers to text during operation in the coming months. We did not test this, as laws in Pennsylvania prohibit the use of phones at any time due to the new Paul Miller’s Law, which took effect earlier this year.
However, the improvements indicate that Tesla is certainly headed toward a much more sentient FSD experience, so much so that Musk’s language seems to be more indicative of a more relaxed experience in terms of overall supervision from the driver, especially with v14.3.
Musk did not release or discuss a definitive timeline for the release of v14.3, especially as v14.2 just rolled out to Early Access Program (EAP) members yesterday. However, v14.1 rolled out to Tesla owners just a few weeks ago in late 2025. There is the potential that v14.3 could be part of the coming Holiday Update, or potentially in a release of its own before the New Year.

Tesla Full Self-Driving v14.2 – Full Review, the Good and the Bad
Tesla rolled out Full Self-Driving version 14.2 yesterday to members of the Early Access Program (EAP). Expectations were high, and Tesla surely delivered.
With the rollout of Tesla FSD v14.2, there were major benchmarks for improvement from the v14.1 suite, which spanned across seven improvements. Our final experience with v14.1 was with v14.1.7, and to be honest, things were good, but it felt like there were a handful of regressions from previous iterations.
While there were improvements in brake stabbing and hesitation, we did experience a few small interventions related to navigation and just overall performance. It was nothing major; there were no critical takeovers that required any major publicity, as they were more or less subjective things that I was not particularly comfortable with. Other drivers might have been more relaxed.
With v14.2 hitting our cars yesterday, there were a handful of things we truly noticed in terms of improvement, most notably the lack of brake stabbing and hesitation, a major complaint with v14.1.x.
However, in a 62-minute drive that was fully recorded, there were a lot of positives, and only one true complaint, which was something we haven’t had issues with in the past.
The Good
Lack of Brake Stabbing and Hesitation
Perhaps the most notable and publicized issue with v14.1.x was the presence of brake stabbing and hesitation. Arriving at intersections was particularly nerve-racking on the previous version simply because of this. At four-way stops, the car would not be assertive enough to take its turn, especially when other vehicles at the same intersection would inch forward or start to move.
This was a major problem.
However, there were no instances of this yesterday on our lengthy drive. It was much more assertive when arriving at these types of scenarios, but was also more patient when FSD knew it was not the car’s turn to proceed.
Can report on v14.2 today there were ZERO instances of break stabbing or hesitation at intersections today
It was a significant improvement from v14.1.x
— TESLARATI (@Teslarati) November 21, 2025
This improvement was the most noticeable throughout the drive, along with fixes in overall smoothness.
Speed Profiles Seem to Be More Reasonable
There were a handful of FSD v14 users who felt as if the loss of a Max Speed setting was a negative. However, these complaints will, in our opinion, begin to subside, especially as things have seemed to be refined quite nicely with v14.2.
Freeway driving is where this is especially noticeable. If it’s traveling too slow, just switch to a faster profile. If it’s too fast, switch to a slower profile. However, the speeds seem to be much more defined with each Speed Profile, which is something that I really find to be a huge advantage. Previously, you could tell the difference in speeds, but not in driving styles. At times, Standard felt a lot like Hurry. Now, you can clearly tell the difference between the two.
It seems as if Tesla made a goal that drivers should be able to tell which Speed Profile is active if it was not shown on the screen. With v14.1.x, this was not necessarily something that could be done. With v14.2, if someone tested me on which Speed Profile was being used, I’m fairly certain I could pick each one.
Better Overall Operation
I felt, at times, especially with v14.1.7, there were some jerky movements. Nothing that was super alarming, but there were times when things just felt a little more finicky than others.
v14.2 feels much smoother overall, with really great decision-making, lane changes that feel second nature, and a great speed of travel. It was a very comfortable ride.
The Bad
Parking
It feels as if there was a slight regression in parking quality, as both times v14.2 pulled into parking spots, I would have felt compelled to adjust manually if I were staying at my destinations. For the sake of testing, at my first destination, I arrived, allowed the car to park, and then left. At the tail-end of testing, I walked inside the store that FSD v14.2 drove me to, so I had to adjust the parking manually.
This was pretty disappointing. Apart from parking at Superchargers, which is always flawless, parking performance is something that needs some attention. The release notes for v14.2. state that parking spot selection and parking quality will improve with future versions.

However, this was truly my only complaint about v14.2.

SpaceX issues statement on Starship V3 Booster 18 anomaly
The incident unfolded during gas-system pressure testing at the company’s Massey facility in Starbase, Texas.
SpaceX has issued an initial statement about Starship Booster 18’s anomaly early Friday. The incident unfolded during gas-system pressure testing at the company’s Massey facility in Starbase, Texas.
SpaceX’s initial comment
As per SpaceX in a post on its official account on social media platform X, Booster 18 was undergoing gas system pressure tests when the anomaly happened. Despite the nature of the incident, the company emphasized that no propellant was loaded, no engines were installed, and personnel were kept at a safe distance from the booster, resulting in zero injuries.
“Booster 18 suffered an anomaly during gas system pressure testing that we were conducting in advance of structural proof testing. No propellant was on the vehicle, and engines were not yet installed. The teams need time to investigate before we are confident of the cause. No one was injured as we maintain a safe distance for personnel during this type of testing. The site remains clear and we are working plans to safely reenter the site,” SpaceX wrote in its post on X.
Incident and aftermath
Livestream footage from LabPadre showed Booster 18’s lower half crumpling around the liquid oxygen tank area at approximately 4:04 a.m. CT. Subsequent images posted by on-site observers revealed extensive deformation across the booster’s lower structure. Needless to say, spaceflight observers have noted that Booster 18 would likely be a complete loss due to its anomaly.
Booster 18 had rolled out only a day earlier and was one of the first vehicles in the Starship V3 program. The V3 series incorporates structural reinforcements and reliability upgrades intended to prepare Starship for rapid-reuse testing and eventual tower-catch operations. Elon Musk has been optimistic about Starship V3, previously noting on X that the spacecraft might be able to complete initial missions to Mars.
