SpaceX preparing Super Heavy, Starbase for booster’s next steps
Amid a flurry of deliveries and work on several new Starship boosters, SpaceX is preparing the first truly finished Super Heavy for its next steps.
Partially completed by early September, Super Heavy Booster 4 (B4) supported SpaceX’s iconic ‘full stack’ fit test back on August 6th before returning to the build site but has mostly just floated around Starbase’s launch and test facilities in the seven weeks since its second trip to the pad. On September 10th, CEO Elon Musk himself suggested that SpaceX had plans to static fire the booster as early as mid-September – more than six weeks ago. Obviously, nothing even approximating Super Heavy testing transpired. Instead, at least relative to rapid-fire Starbase operations in the two years prior, SpaceX has almost absentmindedly worked on the booster, mostly completing partially-finished wire runs that run its full 69m (~225 ft) length.
In the last few weeks, though, the type of work being done on Super Heavy B4 has changed.
On September 26th, to give the Starbase construction crew more room to install giant arms on the orbital pad’s ‘launch tower,’ SpaceX removed Super Heavy B4 from the launch mount for the second time, temporarily relocating it to an unused patch of the pad’s old landing zone. Booster 4 hasn’t been moved since. However, while probably a bit slower than SpaceX would have liked, large-scale work on the Starship launch tower was effectively completed last week with the installation of two giant rocket-catching ‘Mechazilla’ arms.
A great deal of work has also been done on Starbase’s orbital tank farm over the last two months, including the installation of the last few storage tanks, the ‘sleeving’ of those tanks, a great deal of plumbing, and the start of real propellant deliveries. Save for a few days spent testing Starship S20 in late September and mid-October, the pad construction crews that have to evacuate the pad for 6-12 hours for every test have had three full months to work without interruption. Perhaps the most optimistic explanation for the unusually long gap between Booster 4 and Ship 20 rollout and testing is that SpaceX consciously chose to put off vehicle tests to avoid disrupting orbital launch site construction and retasked nearly all Starbase workers for that construction.
Regardless, with the launch tower and orbital tank farm now more or less structurally complete and work already underway to prepare the tank farm to support its first booster tests, most of the work that may have been drawing focus and resources away from ship and booster preparations appears to be wrapping up. That may be why, for the third time, SpaceX technicians began removing a number of Raptor engines from Super Heavy B4 around the start of October.
Aside from removing around a third to half of Super Heavy’s 29 Raptors, SpaceX also began slowly but surely installing parts of a steel heatshield designed to protect those engines during ground testing, ascent, and reentry. Newer Raptors have also been trickling from Starbase’s build site to the launch pad for installation on the booster and more engines will likely be (re)installed as heatshield installation progresses.
Perhaps the most unusual part of recent Super Heavy B4 work is the apparent application of some kind of foam around several racks of pressure vessels (COPVs), hydraulic manifolds, and umbilical connections installed around the booster’s base. Those racks will eventually be enclosed inside steel ‘aerocovers’ already staged beside Super Heavy. A number of Twitter users believe that the foam being selectively applied is for acoustic deadening – meant to protect sensitive electronics, valves, and computers from the brutal environment Super Heavy itself will produce at liftoff and during ground testing.
Ultimately, with Booster 4 work ramping back up and the zenith of orbital pad construction activity now likely behind SpaceX, preparations for major Super Heavy testing will hopefully resume. SpaceX has yet to perform a full Super Heavy wet dress rehearsal (WDR; fully filling a rocket’s tanks and performing a launch countdown) or fire up more than three Raptors on a booster or ship prototype. With any luck, that will finally change in the final months of 2021.
SpaceX has achieved an incredible milestone by launching its 11,000th Starlink satellite into orbit.
This accomplishment occurred during the Starlink Group 17-50 mission, which lifted off on August 19 at 04:01 UTC from Space Launch Complex 4 East at Vandenberg Space Force Base in California.

A Falcon 9 rocket carried 24 Starlink V2 Mini satellites on this flight, successfully deploying them into low Earth orbit approximately one hour after liftoff. The first stage booster, identified as B1097 on its twelfth flight, landed successfully on the droneship Of Course I Still Love You in the Pacific Ocean.
According to tracking data compiled around that date, this deployment brought the total number of Starlink satellites in orbit to just over 11,000.
The Starlink program began with test satellites known as Tintin A and B, launched on February 22, 2018. The first operational batch of 60 Starlink satellites followed on May 24, 2019, when a Falcon 9 rocket lifted off from Cape Canaveral. Those initial satellites marked the start of a rapid expansion that has continued for more than seven years.
SpaceX has conducted hundreds of dedicated Starlink missions since then, routinely launching batches of 20 to 30 satellites at a time using reusable Falcon 9 rockets. By mid-2026, the company had already surpassed 12,000 total satellites launched across all versions, with continuous replacements for units that deorbit as designed to manage space debris.
Looking ahead, SpaceX continues to expand the Starlink constellation to enhance global broadband coverage, capacity, and speed. The network already serves millions of users across more than 160 countries and supports applications ranging from residential internet to maritime, aviation, and emergency services.
Future plans center on next-generation hardware, including larger V3 satellites capable of delivering substantially higher throughput, which require the increased payload capacity of the Starship vehicle currently under development and testing.
In July, SpaceX submitted an application to the Federal Communications Commission seeking authority for a Gen3 constellation of up to 100,000 satellites. These spacecraft would operate in very low Earth orbit shells at altitudes near 325 kilometers and 475 kilometers. The filing requests use of existing Ku, Ka, V, and E band spectrum along with new greenfield W and D band frequencies between 92 and 275 GHz.
SpaceX states that the expanded system aims to deliver multi-gigabit symmetrical broadband to consumers, enterprises, governments, and billions of AI-powered devices worldwide while handling a majority of global internet traffic. Approval and subsequent deployment would depend on regulatory review and the operational readiness of Starship for high-volume launches.
This ambitious scale reflects SpaceX’s ongoing commitment to providing ubiquitous high-speed connectivity from space.
Tesla has opened a new sweepstakes to allow the public to be among the first to take an initial ride in a Cybercab. This all-electric, steering-wheel-less, pedal-less vehicle is the centerpiece of the company’s autonomous ride-hailing platform, Robotaxi.
There are two ways Tesla fans can get to Austin to take part in the first public rides of the Cybercab: by riding on the Robotaxi platform by August 23, or by mailing a very specific entry to their Headquarters at Gigafactory Texas.
Tesla announced the latter portion of the sweepstakes last night:
🚨 Want to win a trip to Austin to ride in one of the first Cybercab rides ever?
Here’s how:
Tesla has opened up a new sweepstakes to ride in a Cybercab upon its public launch. Here’s the details.
There are two methods of entry into the sweepstakes, and they are as follows:… pic.twitter.com/iJRd4evuWo

Tesla will give one entry into the sweepstakes if you mail a 3″ by 5″ piece of paper with your full name, mailing address, telephone number, email address, and date of birth to their address:
Tesla, Robotaxi Sweeps Event
1 Tesla Road,
Austin, TX 78725
There is a limit of one entry per stamped envelope. You can send as many as you’d like, but they must be in separate envelopes.
The company’s unique strategy to give people the opportunity to ride in a Cybercab before pretty much anyone else outside of the company is a hilarious but spot-on representation of how Tesla operates. In classic fashion, they had the perfect response to the event:

Cybercab will launch later this month, it appears, especially as it plans to announce the winners of the sweepstakes on August 25. The car has already been operating internally, as employees have been able to utilize the Cybercab for rides in some capacity, something it announced earlier this month.
Tesla weirdly confirms Cybercab employee rides, a huge milestone
Moving forward, the big goal is to get Cybercab out on the roads and integrated into the public Robotaxi fleet, one that will pick up real-world ride-hailers and give them a ride from Point A to Point B.
No matter which way you cut it, it appears Tesla is close to putting a vehicle with no steering wheel and no pedals on the road to help people travel autonomously.

Tesla has revealed plans through permit submissions for a massive Robotaxi charging hub in Austin, Texas.
Tesla plans to build the Supercharger hub in multiple phases, with the second phase potentially introducing wireless induction charging, something the company has been developing for the Robotaxi fleet.
Initially, 48 Tesla Robotaxi-geared Superchargers will be built on a lot just across from the St. Elmo, Texas, Service Center. There are about 80 additional spots that will not be impacted by phase 1 of the construction process.
Filings show that the second phase of the project will turn those 80 additional spots into wireless charging for Robotaxi, but it might be an error. The Key Notes state that item 3 is listed as “V4 Charging Cabinet to Support 80 Wireless Chargers in Phase 2. However, the drawings point to V3 Cabinets that are already tied to Superchargers:
There are roughly 128 total spots in the lot, but it is unclear if they will all be used for charging based on what appears to be some sort of typo in the blueprint.
A new Robotaxi fleet charging hub is coming soon to Austin, Texas!!

This is among the first Robotaxi charging hubs Tesla has started to develop, as it currently has four others planned throughout various areas: one in Phoenix, one in San Antonio, another in Irving, which will serve the Dallas-Fort Worth area, and another in Las Vegas.
These projects are necessary as Tesla expands its Robotaxi program. Now that preparations have started for the public launch of Cybercab, Robotaxi will likely be expanding aggressively, especially over the next two to three years.
Last night, The Information reported that Tesla was planning to launch Cybercab as soon as the end of August. Hours later, Tesla then announced it was launching a competition for fans to potentially ride in Cybercab during its first public rides.
Tesla’s plan to expand its charging infrastructure in the regions where Robotaxi will initially operate is great preparation for the expanding service. There is still a lot to do, including launching the Cybercab on time.
