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).

SpaceX is partnering with chipmakers to enable Starlink satellite-to-cell service
President Gwynne Shotwell outlined the effort during a space industry conference in Paris.

SpaceX is working with microchip manufacturers to integrate satellite-connectivity hardware into smartphones, advancing its plan for direct-to-device services through Starlink.
The move follows the company’s $17 billion acquisition of wireless spectrum from EchoStar Corp., a deal that positions SpaceX to operate more independently of traditional telecom carriers.
President Gwynne Shotwell outlined the effort during a space industry conference in Paris this week, as noted in a Bloomberg News report.
Starlink direct-to-device
Starlink currently serves millions of customers in over 100 countries, primarily through ground-based dishes. The company, however, is now expanding into satellite-to-cell service, which should enable unmodified phones to connect directly with orbiting satellites. While SpaceX has a partnership with T-Mobile US, the EchoStar spectrum purchase gives it more control to negotiate with global carriers on its own terms.
“We’re working with chip manufacturers to get the proper chips in phones,” the SpaceX President stated. “We will now be initiating discussions with telcos in a different way now. Now it’s our spectrum, but we want to work with them, almost providing capacity and wholesaling capacity to their customers.”
The company plans to launch satellites capable of supporting its direct-to-device business within two years, with early mobile phone testing expected by late 2026.
Starship program continues test flights
Shotwell also addressed SpaceX’s Starship program, which recently completed its 10th test flight in August. She said the mission met all objectives, providing a critical morale boost to teams after a challenging development year.
“My Starship team needed that win,” Shotwell noted. “Development programs always are kind of a 24/7 operation, and I was really pleased for them.”
SpaceX is planning to fly one more iteration of the current Starship prototype, known as V2, before transitioning to the next-generation V3 vehicle. That version, expected to debut late this year or early 2026, is designed to be more capable and support eventual crewed missions to the Moon and Mars.
“The V3, which we want to fly hopefully late this year, but maybe early next year, is really the vehicle that could take humans to the moon and Mars,” Shotwell stated.

Elon Musk says xAI has a chance to reach AGI with Grok 5
The comment came after Grok 4 posted strong results on the ARC-AGI benchmark.

Elon Musk suggested this week that his artificial intelligence startup xAI has the potential to reach artificial general intelligence (AGI) with the next version of its large language model, Grok 5.
The comment came after Grok 4 posted strong results on the ARC-AGI benchmark, which tests reasoning and problem-solving ability.
Musk sees Grok 5 as AGI candidate
In a post on X, user @amXFreeze shared the latest results of the ARC-AGI leaderboard, which showed Grok 4 outpacing rival systems such as OpenAI’s ChatGPT in problem-solving and open program synthesis tasks.
Musk reacted to the performance by stating that “I now think xAI has a chance of reaching AGI with Grok 5. Never thought that before.”
Artificial General Intelligence (AGI) refers to an AI system that is capable of matching or surpassing human-level intelligence across tasks such as thinking, reasoning, and other domains by a notable margin, as noted in a report from Benzinga. AI companies today are actively pursuing AGI.
xAI’s speed
While xAI was only established in March 2023, the startup has grown aggressively. Since its founding, it has rapidly risen in the AI segment and its Grok large language model has become a mainstream option for everyday users, especially on social media platform X. The company is still growing aggressively, and it is currently expanding its Colossus supercomputer cluster in Memphis.
During xAI’s Engineering Open House event in San Francisco in its early days, Elon Musk highlighted that speed would be the company’s primary competitive edge. To highlight this, Musk stated that “No SR-71 Blackbird was ever shot down and it only had one strategy: to accelerate.” So far, xAI is definitely playing this role very well.

Tesla lands new partnership with Uber as Semi takes center stage
Tesla and Uber will work together, using the company’s all-electric Semi, to make sustainable Class 8 electric trucks more affordable with three main strategies: Subsidized Pricing, Predictable Growth, and Optimization of Utilization.

The Tesla Semi has led to a new partnership between the company and Uber, as the two are launching a program that aims to revolutionize logistics by making sustainable commercial vehicles more accessible.
Uber announced on Tuesday that it was planning to launch the Dedicated EV Fleet Accelerator Program in a new partnership with Tesla. Uber’s Freight division is mainly responsible for the new program, which it calls a “first-of-its-kind buyer’s program designed to make electric freight more affordable and accessible by addressing key adoption barriers.”
Tesla and Uber will work together, using the company’s all-electric Semi, to make sustainable Class 8 electric trucks more affordable with three main strategies: Subsidized Pricing, Predictable Growth, and Optimization of Utilization.
- Subsidized Price: Fleets purchasing Tesla Semis through this program will receive a subsidy on the purchase price.
- Predictable Growth: Fleets will integrate their Tesla Semis into Uber Freight’s dedicated solutions for shippers for a pre-determined period. This creates an opportunity for carriers to forecast revenue with confidence, while shippers gain consistent access to reliable, zero-emission capacity.
- Optimize Utilization: Uber Freight taps into its extensive freight network to match carriers with consistent, high-quality freight from our strong shipper base—helping ensure the addition of these Tesla Semis stay fully utilized and carriers see dedicated, real, measurable returns from the start
Tesla will work directly with interested companies to iron out technical details about the Semi, as well as its cost of ownership based on the tailored needs of their business. Fleets can expect savings on the first day, Uber says, as they will avoid diesel fuel costs and reduced maintenance, a widely known advantage of EVs.
Uber announced that it had partnered with select carriers to pilot the Dedicated EV Fleet Accelerator Program prior to its launch:
“During the 2-month pilot program, the Tesla Semis showcased both reliability and efficiency for Uber Freight’s shipper network. Over 394 hours of drive time, carriers covered 12,377 miles. With an average net energy consumption of just 1.72 kWh per mile and only 60 hours of total charge time, these results highlight the operational viability of Tesla Semis on demanding freight lanes. “
In its press release launching the program, Uber effectively highlights how the use of the Semi can impact a company’s margins and profitability through fuel savings, reduced maintenance costs, and lower total cost of ownership.
This is something that turns so many people away from gas cars and toward EVs, so it’s no surprise that Uber wanted to emphasize this point on a larger scale with a company that utilizes a fleet of vehicles.
Tesla Semi shows strong results in ArcBest’s real-world freight trial
Tesla has been experimenting with a select group of companies, as well. It partnered with PepsiCo. several years ago, in an effort to launch a pilot program for the Semi. It had excellent results, showing higher efficiency, lower costs, and an exceptional ability to handle long runs.
Drivers have had a lot of positive things to say:
The Semi will enter mass production next year, but we anticipate that some companies will commit to Uber’s new platform well before then.
