After rapidly stacking Ship 20 and Booster 4 the evening prior, SpaceX appears to have begun testing a fully stacked Starship rocket for the first time ever.
Though the test SpaceX subjected Starship to was by no means ambitious and in spite of the fact that it no longer appears that Ship 20 and Booster 4 will ever fly, the first test of the first fully integrated prototype of a new rocket is still an immensely significant achievement – particularly so for the largest rocket ever built.
Standing around 119 meters (~390 ft) tall, Starship is unequivocally the largest and most voluminous rocket ever built. With its 29 Raptor V1 engines, the fully assembled Ship 20 and Booster 4 (B4) stack would have likely weighed around 4000-5000 tons (9-11M lb) and been able to produce around 5400 tons (11.9M lbf) of thrust at liftoff – substantially heavier and more powerful than Saturn V or N1, the largest rockets ever successfully and unsuccessfully launched.
For its first fully-integrated test, though, SpaceX appears to have put Starship through a fairly limited cryogenic proof – a test where flammable propellant is replaced with a similarly cold (cryogenic) fluid that’s similar enough to subject a rocket to similar thermal and mechanical stresses. For Ship 20 and Booster 4’s combined debut, Super Heavy was filled maybe 10-20% and Starship around 25-50% of the way with either liquid nitrogen (LN2) or a combination of LN2 and liquid oxygen (LOx). It’s difficult to tell but it’s unlikely any methane (LCH4) fuel was involved.
Back on the ground, Starship S20 completed five separate cryogenic proof tests before its first test on top of Super Heavy. More importantly, Ship 20 successfully completed several static fire tests, each of which also functioned as a wet dress rehearsal with LCH4/LOx propellant. Booster 4 had also passed several cryogenic proof tests. In that sense, it’s unlikely that SpaceX had a great deal of uncertainty as to whether either prototype would be able to complete yet another test.
Beyond the basic mechanical demonstration that Super Heavy Booster 4 is strong enough to support a partially loaded Starship, which probably wasn’t in doubt, it’s likely that the main purpose of this first full-stack cryoproof was to ensure that all the systems required to fuel Starship on top of Super Heavy were working as expected. That’s no small feat given that Starship is both the tallest rocket and largest upper stage ever assembled. To fully fuel a Starship for an orbital launch, around 1200 tons (~2.65M lb) of propellant (or LN2 for a cryoproof) – equivalent to the weight of more than two entire Falcon 9 rockets – must be pumped around 85 meters (~275 ft) up Starbase’s integration tower.
That requires thousands of feet of plumbing and a symphony of giant valves and pumps, all of which must work in concert – without leaking, jamming, or freezing – to fuel Starship. As such, the first full-stack cryoproof was just as much – or more – of a test of the orbital launch site’s launch/integration tower and tank farm. That first test is just the start of a long process, though, and it’s likely that SpaceX will attempt an increasingly ambitious series of tests with Booster 4 and Ship 20 over the next week or two.
That could involve simply filling the rocket further and raising its tank pressures or it could potentially culminate in a partial wet dress rehearsal with methane and oxygen propellant in place of liquid nitrogen. There’s an even smaller chance that SpaceX could attempt to static fire Super Heavy B4 for the first time, although sources like NASASpaceflight are no longer confident that Booster 4 will be static fired before retirement. More to the point, it would be uncharacteristically risky behavior from SpaceX to perform the very first static fire of a new prototype with an already proven Starship sitting on top of it. An anomaly as small as an uncontrolled fire – far from uncommon for Starships – could easily risk the catastrophic destruction of both stages, which would itself run the risk of significantly damaging the orbital launch site, which could easily take months to repair.
Nonetheless, there’s still a chance. SpaceX has opportunities for additional testing on March 17th, 18th, 21st, and 22nd.
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.
You can ride along with us in our first Cybercab ride from the We, Robot event in October 2024. The video is embedded below:

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.
