SpaceX Falcon 9 rideshare launch to send a commercial lander to the Moon in 2019
According to a press release published on September 11 in conjunction with the 2018 World Satellite Business Week conference, satellite rideshare organizer Spaceflight Industries and SpaceX are on track for the first functionally dedicated rideshare mission to a relatively high-energy geostationary transfer orbit.
Expected to occur as soon as early 2019, Spaceflight has arranged the addition of “several undisclosed payloads” but was able to confirm that Israel-based company SpaceIL’s lunar lander spacecraft – deemed Sparrow – will be onboard Falcon 9 come launch, potentially paving the way for the first-ever commercial spacecraft landing on an extraterrestrial planet (or moon).

A bit more than “Uber for space”
Although any rocket or satellite launch on its own is already a sort of wildly complex symphony, rideshare missions – potentially carrying dozens of individual satellites – up the intensity by a significant degree, demanding magnitudes more separation events (i.e. satellite deployments), a labyrinth-like hell for the payload organizer tasked with herding dozens of distinct spacecraft into one payload fairing come launch time, and often multiple orbit drop-off points.
Still, at the cost of some amount of added risk (of both failures and launch delays) and less flexibility to pick and choose orbits, rideshare customers are granted launch prices that should – in theory – be fundamentally unbeatable with dedicated launches, using an entire rocket for no more than a handful of payloads. Intriguingly, at least in the case of Spaceflight Industry’s first organized rideshare to geostationary orbit, Falcon 9’s capabilities are truly unbeatable at SI’s cost per customer, thanks to the reality that such a high-energy orbit is functionally unreachable to the array of dedicated smallsat rockets with purportedly imminent commercial launch debuts (Rocket Lab, Virgin Orbit, Vector, and others).

Even more intriguingly, it appears that this rideshare will go so far as to offer a ride to a true, circular geostationary orbit for a few copassengers, versus the highly-elliptical parking orbit Falcon 9 will place the whole payload stack in. It has yet to be specifically confirmed what the primary (heaviest) payload will be for this inaugural geostationary rideshare, but nearly all available signs are pointing towards a fairly large (5000 kilogram) communications satellite built by Space Systems Loral (SSL). Further, the satellite itself will serve as the mode of transportation to carry a number of copassenger spacecraft from SpaceX’s geostationary transfer orbit to the final circular orbit roughly 22,500 mi (~36,000 km) above Earth’s surface.
Satellite rideshares, brought to you by the US military?
The story deepens further still. All available signs also suggest a high probability that this launch will become one of SSL’s first operational uses of a currently-experimental rideshare plan known as PODS, in which fairly small satellites would quite literally piggyback on large, commercial satellites into exotic and high-energy orbits, far beyond the low Earth orbits primarily available to rideshare payloads. This could open a whole new world of affordable, cubesat-style exploration, ranging from student-led missions with unprecedented reach to fleets of NASA-funded scientific smallsats, and perhaps even self-propelled interplanetary cubesats once miniature propulsion is available.

Funded and sponsored to some extent by US military research agency DARPA, it just so happens that an SSL-built satellite launched by SpaceX six months ago – Hispasat 30W-6, March 2018 – successfully debuted that PODS rideshare technology in an experimental test, deploying a secret secondary satellite funded by DARPA. That success has apparently paved the way for future PODS rideshares, and it looks like SSL may be opting to contract out the specialized task of manifesting launches and wrangling multiple copassenger satellites to Spaceflight Industries.
The primary SSL-built spacecraft, likely Indonesia’s PSN-6 geostationary communications satellite, is expected to weigh approximately 5000 kg (~11,000 lb), while SpaceIL’s commercial Sparrow lunar lander and spacecraft is currently pegged around 600 kg (1300 lb). Aside from that duo, SSL PODS can support anywhere from one to several satellite deployer add-ons, and each copassenger spacecraft has a mass limit of 90-150 kg (~200-330 lb).
As a consequence, the final mass of those 3+ integrated satellites and their associated payload adapters could easily wind up around 6500-7000 kg, a payload SpaceX’s Falcon 9 Block 5 rocket has proven itself capable of handling (Telstar 18V and 19V), but only to a fairly low-energy geostationary transfer orbit (18,000 km vs. a full GTO’s 36,000 km apogee). It’s unclear how SpaceIL’s Sparrow lunar lander would handle a relatively low-energy insertion orbit, although the PSN-6 communications satellite would certainly be able to make up for the shortfall with its own propellant supply and rocket engines.
Prior to this geostationary rideshare, SpaceX and Spaceflight Industry’s first mission together – a rideshare of ~70 satellites to low Earth orbit – is expected to occur no earlier than October or November 2018 from Vandenberg Air Force Base, California.

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.
