SpaceX delivers largest commercial satellite in kick off of Falcon 9 marathon
SpaceX has successfully completed its 13th launch of 2018, kicking off a marathon of three new Falcon 9 Block 5 booster debuts with the launch of the Telstar 19V communications satellite, potentially breaking the record for the largest commercial satellite ever launched at 7000 kg (15,500 lb).
Despite the heft of its payload and partially thanks to a slightly lower parking orbit for the satellite, Falcon 9 booster B1047 – the second Block 5 booster to roll off the assembly line – managed to successfully land aboard the autonomous spaceport drone ship (ASDS) Of Course I Still Love You (OCISLY), stationed approximately 650 km (400 mi) off the Florida coast at launch time.
While the booster was unable to maintain a live video feed through its high-speed reentry and Atlantic landing, SpaceX’s cameras on OCISLY managed to reconnect a few seconds after touchdown to show the 50-meter (160-foot) tall rocket safely resting on the drone ship. As the webcast host noted, Falcon 9 Block 5 features a number of prominent upgrades designed to enable levels of reusability and reliability essentially unprecedented in the world of orbital rocketry.

Rocket trials
Now more than two months after the first Block 5 booster’s – B1046 – debut in May 2018, the software engineer hosting SpaceX’s Telstar 19V webcast was likely speaking more from a place of experience than of hope. Per CEO Elon Musk’s press call just prior to Block 5’s debut, he noted that SpaceX intended to conduct an extensive analysis of that pathfinder booster, including significant disassembly and perhaps some limited destructive testing of certain critical or high-risk components. Musk didn’t expect B1046 to fly for at least another “couple of months”.
This is critical because SpaceX’s manifest over the next several weeks is fairly aggressive – Iridium-7 is scheduled to lift off from Vandenberg, CA three days from today (July 25th), the next Florida launch is aiming for a static fire next weekend and a launch NET 1:19 am EDT August 2, and the second imminent Florida mission is penciled in for launch NET 11:35 pm EDT August 17. Those rapid-fire Florida launches will push both SpaceX’s pad and drone ship turnaround capabilities to their limits, requiring almost non-stop work to ensure both are available for the next mission in two weeks or less.

Not to be (at least relatively) one-upped, SpaceX’s Vandenberg launch pad – known as SLC-4E – is scheduled to push its own turnaround limits by flying two missions in roughly 40 days, just shy of the current SpaceX record of 36 days between launches. Perhaps more excitingly, that September 4 SAOCOM 1A mission looks like a prime candidate for the debut of SpaceX’s yet-unused Californian landing zone, barely spitting distance from the SLC-4E launch pad.
Still, the question remains: what boosters are going to launch these four missions?
- B1051 is not believed to have left the Hawthorne, CA factory yet, and has been stated by NASA to be reserved for the first uncrewed Crew Dragon mission (DM-1), unlikely to occur before Q4 2018.
- B1050 is currently on-stand in McGregor, TX and is likely to be shipped to a launch pad within a week or two.
- B1049 was almost certainly shipped to Florida to support either of the two upcoming August launches.
- B1048 will launch Iridium-7 on July 25, land on Just Read The Instructions, and likely remain in California for future VAFB missions.
- B1047 just successfully launched Telstar 19V (July 22) and will be brought back to Port Canaveral over the next several days before heading to one of SpaceX’s Florida refurbishment facilities, presumably to prepare for an imminent future launch.
- B1046 is likely disassembled in Hawthorne, CA, unable to support a launch for another few weeks – perhaps it’s nearly ready, however

Put simply, it seems almost impossible for SpaceX to accomplish its ambitious manifest over the next 4-6 weeks without reusing a freshly-recovered Falcon 9 Block 5 booster. B1046 is a possibility, as is B1047 or B1048, although the latter two options would smash SpaceX’s previous record for Falcon booster turnaround (~70 days) by more than half, requiring in a return to shore, refurbishment or nondestructive analysis, and preparation for a static fire in as few as ~14-21 days.
Regardless, B1047’s successful Telstar 19V launch and landing have kicked off what is bound to be an extremely exciting period for SpaceX and its aspirations of highly-reusable rocketry.

Tesla launches Cybertruck vehicle-to-grid program in Texas
The initiative was announced by the official Tesla Energy account on social media platform X.
Tesla has launched a vehicle-to-grid (V2G) program in Texas, allowing eligible Cybertruck owners to send energy back to the grid during high-demand events and receive compensation on their utility bills.
The initiative, dubbed Powershare Grid Support, was announced by the official Tesla Energy account on social media platform X.
Texas’ Cybertruck V2G program
In its post on X, Tesla Energy confirmed that vehicle-to-grid functionality is “coming soon,” starting with select Texas markets. Under the new Powershare Grid Support program, owners of the Cybertruck equipped with Powershare home backup hardware can opt in through the Tesla app and participate in short-notice grid stress events.
During these events, the Cybertruck automatically discharges excess energy back to the grid, supporting local utilities such as CenterPoint Energy and Oncor. In return, participants receive compensation in the form of bill credits. Tesla noted that the program is currently invitation-only as part of an early adopter rollout.
The launch builds on the Cybertruck’s existing Powershare capability, which allows the vehicle to provide up to 11.5 kW of power for home backup. Tesla added that the program is expected to expand to California next, with eligibility tied to utilities such as PG&E, SCE, and SDG&E.
Powershare Grid Support
To participate in Texas, Cybertruck owners must live in areas served by CenterPoint Energy or Oncor, have Powershare equipment installed, enroll in the Tesla Electric Drive plan, and opt in through the Tesla app. Once enrolled, vehicles would be able to contribute power during high-demand events, helping stabilize the grid.
Tesla noted that events may occur with little notice, so participants are encouraged to keep their Cybertrucks plugged in when at home and to manage their discharge limits based on personal needs. Compensation varies depending on the electricity plan, similar to how Powerwall owners in some regions have earned substantial credits by participating in Virtual Power Plant (VPP) programs.

Samsung nears Tesla AI chip ramp with early approval at TX factory
This marks a key step towards the tech giant’s production of Tesla’s next-generation AI5 chips in the United States.
Samsung has received temporary approval to begin limited operations at its semiconductor plant in Taylor, Texas.
This marks a key step towards the tech giant’s production of Tesla’s next-generation AI5 chips in the United States.
Samsung clears early operations hurdle
As noted in a report from Korea JoongAng Daily, Samsung Electronics has secured temporary certificates of occupancy (TCOs) for a portion of its semiconductor facility in Taylor. This should allow the facility to start operations ahead of full completion later this year.
City officials confirmed that approximately 88,000 square feet of Samsung’s Fab 1 building has received temporary approval, with additional areas expected to follow. The overall timeline for permitting the remaining sections has not yet been finalized.
Samsung’s Taylor facility is expected to manufacture Tesla’s AI5 chips once mass production begins in the second half of the year. The facility is also expected to produce Tesla’s upcoming AI6 chips.
Tesla CEO Elon Musk recently stated that the design for AI5 is nearly complete, and the development of AI6 is already underway. Musk has previously outlined an aggressive roadmap targeting nine-month design cycles for successive generations of its AI chips.
Samsung’s U.S. expansion
Construction at the Taylor site remains on schedule. Reports indicate Samsung plans to begin testing extreme ultraviolet (EUV) lithography equipment next month, a critical step for producing advanced 2-nanometer semiconductors.
Samsung is expected to complete 6 million square feet of floor space at the site by the end of this year, with an additional 1 million square feet planned by 2028. The full campus spans more than 1,200 acres.
Beyond Tesla, Samsung Foundry is also pursuing additional U.S. customers as demand for AI and high-performance computing chips accelerates. Company executives have stated that Samsung is looking to achieve more than 130% growth in 2-nanometer chip orders this year.
One of Samsung’s biggest rivals, TSMC, is also looking to expand its footprint in the United States, with reports suggesting that the company is considering expanding its Arizona facility to as many as 11 total plants. TSMC is also expected to produce Tesla’s AI5 chips.

Anti-Tesla union leader ditches X, urges use of Threads instead
Tesla Sweden and IF Metall have been engaged in a bitter dispute for over two years now.
Marie Nilsson, chair of Sweden’s IF Metall union and a prominent critic of Tesla, has left X and is urging audiences to follow the union on Meta’s Threads instead.
Tesla Sweden and IF Metall have been engaged in a bitter dispute for over two years now.
Anti-Tesla union leader exits X
In a comment to Dagens Arbete (DA), Nilsson noted that her exit from X is not formally tied to IF Metall’s long-running labor dispute with Tesla Sweden. Still, she stated that her departure is affected by changes to the platform under Elon Musk’s leadership.
“We have stayed because many journalists pick up news there. But as more and more people have left X, we have felt that the standard has now been reached on that platform,” she said.
Jesper Pettersson, press officer at IF Metall, highlighted that the union’s departure from X is only indirectly linked to Tesla Sweden and Elon Musk. “Indirectly it does, since there is a lot of evidence that his ownership has caused the change in the platform to be so significant.
“We have nevertheless assessed that the platform had value for reaching journalists, politicians and other opinion leaders. But it is a microscopic proportion of the public and our members who are there, and now that value has decreased,” Petterson added.
IF Metall sees Threads as an X alternative
After leaving X, IF Metall has begun using Threads, Meta’s alternative to the social media platform. The union described the move as experimental, noting that it is still evaluating how effective the platform will be for outreach and visibility.
Pettersson acknowledged that Meta also does not operate under Sweden’s collective bargaining model, but said the union sees little alternative if it wants to remain visible online.
“In a perfect world, all large international companies would be supporters of the Swedish model when they come here. But unfortunately, the reality is not like that. If we are to be visible at all in this social media world, we have to play by the rules of the game. The alternative would be to become completely invisible, and that would not benefit our members,” he said.
