SpaceX Falcon 9 rocket sets reusability record, launches heaviest payload yet
SpaceX Falcon 9 booster B1051 has become the company’s ‘fleet leader’ after acing its 12th orbital-class launch and landing – a new record for the rocket family.
After a roughly 90-minute weather delay, Falcon 9 lifted off without issue around 12:48 am EST on March 19th. Booster B1051 touched down on drone ship Just Read The Instructions (JRTI) about nine minutes later, followed by the successful deployment of 53 Starlink V1.5 satellites just over an hour after launch. Starlink 4-12 was SpaceX’s 11th successful launch in the first 11 weeks of 2022. SpaceX CEO Elon Musk says that Starlink 4-12 was also the heaviest payload ever launched by Falcon 9, weighing in at 16.25 metric tons or ~35,800 pounds.

It’s not entirely clear how SpaceX was able to expand Falcon 9’s performance envelope or how far the envelope was pushed. In May 2019, Musk actually claimed that the Starlink V0.9 payload would weigh “18.5 tons” and be SpaceX’s heaviest payload ever, whereas three years later he says Starlink 4-12 set a new record of 16.25 metric tons. Assuming Musk was referring to short tons in 2019 and that SpaceX’s Starlink payload adapter and the tensioning rods that hold the stack together are roughly the same weight (~3 mT) three years later, the true total mass of Starlink 4-12’s payload could be as high as 19-19.5 metric tons (~42,000 lb). Its 53 Starlink V1.5 satellites, meanwhile, would weigh about 307 kilograms (~675 lb) each.
In other words, Starlink 4-12’s record-breaking payload could be up to 2.5 metric tons – about 15% – heavier than the Starlink V0.9 payload that set SpaceX’s internal record in 2019.


SpaceX says a Falcon 9 rocket is on track to launch Starlink 4-12 – a new batch of 53 satellites – no earlier than (NET) 11:24 pm EST on Friday, March 18th (03:24 UTC 19 March).
While ‘just’ the latest in an increasingly routine line of Starlink launches, SpaceX has confirmed that the mission will also set a new record for Falcon 9 reusability. Setting minor records is practically just as common for the average SpaceX launch but this particular record is more significant: if all goes according to plan, booster B1051 will become the first Falcon 9 first stage to complete 12 orbital-class launches and landings, pushing the envelope that much further.
The second oldest Falcon 9 booster that’s still operational, B1051 debuted in a significant way on March 2nd, 2019 by supporting Demo-1, Crew Dragon’s first uncrewed test flight. The launch was a perfect success and simultaneously kicked off the prolific careers of Crew Dragon and Falcon 9 B1051, both of which continue to have an excellent track record. Since Demo-1, B1051 has also supported the launches of Canada’s RADARSAT constellation, SiriusXM’s SXM-7 radio satellite, and 469 Starlink spacecraft spread over eight separate missions.
Starlink 4-12 will be its 12th launch and is set to occur just over two weeks after the third anniversary of its launch debut, translating to an average of one launch every three months or ~93 days. As an older booster and a fleet leader for several reusability milestones, B1051’s average turnaround time between launches – ~100 days – isn’t exceptionally impressive, though the booster has still accomplished a great deal.


However, newer boosters like B1058 and B1060 – both of which have much faster average turnaround times – are tied with B1051 at eleven flights each. One of the two is almost guaranteed to supersede B1051 in the very near future and become SpaceX’s new fleet leader, meaning that either B1058 or B1060 is likely to be the first to set new reusability records after B1051’s 12th flight.
Falcon 9 B1060, for example, has flown 11 times in 611 days, averaging one launch every 55 days and 61 days per reuse. B1060’s last two turnarounds have been under 50 days. B1058 is very similar. In other words, both B1058 and B1060 could feasibly overtake B1051 as early as May or June 2022 and could both potentially complete their 15th, 16th, or even 17th launches before the end of the year.
As such, this could be Falcon 9 B1051’s last opportunity to lead SpaceX’s fleet of Falcon boosters. Tune into SpaceX’s official webcast to watch Starlink 4-11 live around 11:10 pm EST (03:10 UTC).

Tesla says texting and driving capability is coming ‘in a month or two’
“In the next month or two, we’re going to look at the safety statistics, but we’re going to allow you to text and drive, essentially.”
Tesla CEO Elon Musk said that within the next month or two, the company will be able to open the ability for people to text and drive because its Full Self-Driving suite will be robust enough to allow drivers to take their attention away from the road.
In its current state, Tesla Full Self-Driving is a supervised driver assistance suite that requires the vehicle operator to maintain control of the vehicle and pay attention to the road surroundings.
However, the company has been aiming to release a fully autonomous version of the Full Self-Driving suite for years, teasing its future potential and aiming to release a Level 5 suite as soon as possible.
CEO Elon Musk believes the company is on the cusp of something drastic, according to what he said at yesterday’s Annual Shareholder Meeting.
One thing Musk hinted at was that the company should be able to allow those sitting in the driver’s seat of their cars to text and drive “in the next month or two,” as long as the statistics look good.
He said:
“In the next month or two, we’re going to look at the safety statistics, but we’re going to allow you to text and drive, essentially.”
The company recently transitioned to its v14 Full Self-Driving suite, which is its most robust to date, and recently expanded to Cybertruck, completing its rollout across the vehicle lineup.
Currently, Tesla is running v14.1.5, and when major improvements are made, that second number will increase, meaning v14.2 will be the next substantial improvement.
Musk said that v14.3 will be when you can “pretty much fall asleep and wake up at your destination.”

We’ve heard a considerable amount of similar statements in the past, and Tesla owners have been conditioned to take some of these timeframes with autonomous driving with a grain of salt.
However, with the upgrades in FSD over the past few months, especially with the rollout of Robotaxi in Austin, which does not utilize anyone in the driver’s seat for local roads, it does not seem as if autonomy is that far off for Tesla.

Tesla Semi undergoes major redesign as dedicated factory preps for deliveries
The Semi has been one of the most anticipated products in the Tesla lineup due to the disruption it could cause in the trucking industry.
Tesla put its all-electric Semi truck through quite a major redesign as its dedicated factory for the vehicle is preparing for initial deliveries to the public starting next year.
The Semi has been one of the most anticipated products in the Tesla lineup due to the disruption it could cause in the trucking industry.
It has already been in numerous pilot programs for some pretty large companies over the past couple of years, PepsiCo. being one of them, and it is moving toward first deliveries to other companies sometime in 2026.
Yesterday at the 2025 Annual Shareholder Meeting, Tesla unveiled its new Semi design, which underwent a pretty significant facelift to match the aesthetic and vibe of the other vehicles in the company’s lineup.
Additionally, Tesla announced some other improvements, including changes to efficiency, and some other changes that we did not get details on yet.
The first change was to the design of the Semi, as Tesla adopted its blade-like light bar for the Class 8 truck, similar to the one that is used on the new Model Y and the Cybertruck:

There also appear to be a handful of design changes that help with aerodynamics, as its efficiency has increased to 1.7 kWh per mile.
Tesla also said it has an increased payload capability, which will help companies to haul more goods per trip.
All of these changes come as the company’s Semi Factory, which is located on the same property as its Gigafactory in Reno, Nevada, is just finishing up. In late October, it was shown that the Semi facility is nearly complete, based on recent drone imagery from factory observer HinrichsZane on X:
The factory will be capable of producing about 50,000 Tesla Semi units annually when it is completely ramped. The company has major plans to help get the Semi in more fleets across the United States.
Other entities are also working to develop a charging corridor for electric Class 8 trucks. The State of California was awarded $102 million to develop a charging corridor that spans from Washington to Southern California.
Another corridor is being developed that spans from Southern California to Texas, and 49 applicants won $636 million from the Department of Transportation for it.
Tesla requested funding for it, but was denied.
The Semi has been a staple in several companies’ fleets over the past few years, most notably that of Frito-Lay and PepsiCo., who have reported positive experiences thus far.
Musk said last year that the Semi had “ridiculous demand.”

Tesla Cybercab production starts Q2 2026, Elon Musk confirms
Elon Musk highlighted that the fully autonomous vehicle will be the first Tesla designed specifically for unsupervised self-driving.
Tesla CEO Elon Musk confirmed that production of the company’s autonomous Cybercab will begin in April 2026, and its production targets will be quite ambitious.
Speaking at Tesla’s 2025 Annual Shareholder Meeting, Musk highlighted that the fully autonomous vehicle will be the first Tesla designed specifically for unsupervised self-driving.
A robotaxi built for an autonomous world
Musk described the Cybercab as a clean-slate design optimized for autonomy, with no steering wheel, pedals, or side mirrors. “It’s very much optimized for the lowest cost per mile in an autonomous mode,” Musk said, adding that every Tesla produced in recent years already carries the hardware needed for full self-driving.
The Cybercab will be assembled at Giga Texas and will serve as the company’s flagship entry into the commercial robotaxi market. Musk emphasized that the project represents Tesla’s next evolutionary step in combining vehicle manufacturing, artificial intelligence, and mobility services.
One Cybercab every ten seconds
Musk reiterated that the Cybercab’s production process is more closely modeled on consumer electronics assembly than on traditional automotive manufacturing. This should pave the way for outputs that far exceed conventional automotive products.
“That production is happening right here in this factory, and we’ll be starting production in April next year. The manufacturing system is unlike any other car. The manufacturing system of the Cybercab, it’s closer to a high volume consumer electronics device than it is a car manufacturing line. So the net result is that I think we should be able to achieve, I think, ultimately, less than a 10-second cycle time, basically a unit every 10 seconds.
“What that would mean is you could get on a line that would normally produce, say, 500,000 cars a year at a one minute cycle time, Model Y. This would be maybe as much as 2 million or 3 million, maybe ultimately it’s theoretically possible to achieve a 5 million unit production line if you can get to the 5-second cycle time,” the CEO said.
