SpaceX’s first orbital Starship prototype prepares for proof tests

Published

on

Several days after SpaceX’s first orbital-class Starship prototype took a second trip to a nearby launch site, the rocket is on its way to one of two suborbital launch mounts.

Once installed on the steel structure, Starship prototype 20 (S20) will finally be ready for – at minimum – two crucial tests: a cryogenic proof and static fire. According to highway closures filed by SpaceX late last week, the first of those tests could apparently begin as early as Thursday, August 19th, potentially setting Starship S20 up to attempt at least one major milestone next week.

On August 13th, SpaceX rolled Starship S20 back to the launch site a week after the rocket was sent to the pad to be briefly stacked on top of a Super Heavy booster – an event that appears to have been something like 50% photo opportunity, 50% test objective. Neither the booster or ship were fully complete at the time and both ultimately required at least another week or two of outfitting and plumbing to be ready for ground testing – let alone flight. Aspirationally, the same pair – Ship 20 and Booster 4 – could be the first to attempt a true orbital Starship launch sometime later this year.

Since its second rollout, Ship 20 has more or less stayed in one place as workers continuously swarmed about the rocket on boom and scissor lifts. Over the last four days, not much has visually changed save for the installation of a handful of heat shield tiles, but the focus clearly centered around the Starship’s ‘raceway’ – a clutch of plumbing and wiring that runs most of the length of the vehicle’s back. Virtually all rockets have them and Starship is no different with a raceway packed with avionics wire runs, plumbing for propellant loading, and smaller lines for pressurization and hydraulics.

While it’s not entirely clear what specific work has been done over the last few days or why it wasn’t done back at the build site, where CEO Elon Musk himself has said such tasks are more easily done, it’s clear that Starship S20 does have a more refined raceway than any ship before it. In recent days, SpaceX has also begun to install structural elements that strongly imply that S20 will be the first Starship to receive a raceway aerocover – not unlike those on Falcon boosters – to protect its external wiring and plumbing in flight.

Regardless, once Starship S20 is installed on one of SpaceX’s two suborbital launch mounts, the vehicle will most likely be prepared for a routine cryogenic proof test. To pass, Starship will need to survive significant thermal and mechanical stress as its tanks are filled with supercool liquid nitrogen and pressurized to at least 6 bar (~90 psi). At this point, a Starship prototype hasn’t failed a cryo proof in more than a year, so the test should be fairly routine.

Curiously, after spending weeks modifying Mount B with a series of hydraulic rams meant to simulate the thrust of Ship 20’s six Raptor engines during its cryo proof(s), SpaceX removed all of that extra hardware just prior to the Starship’s second rollout and now-imminent installation on said mount. Regardless of why, that decision likely means that Starship S20 will move directly to static fire testing once it passes cryo proofing. Given that Ship 20 appears to be on track to be the first Starship prototype of any kind to fire more than three Raptors at a time, that static fire campaign will likely be somewhat cautious, possibly beginning with just 1-3 engines and then moving to four, five, or straight to six.

SpaceX could also throw caution to the wind (not implausible as evidenced by the removal of Pad B’s unused thrust rams) and install and attempt to fire all six Raptors immediately after Ship 20 completes a cryo proof. Based on road closures filed by SpaceX, that testing could begin as early as 5pm to 11pm CDT on Thursday, August 19th. A backup window is also scheduled from 6am to 12pm CDT on August 20th.

Tesla’s Giga Nevada has reached an impressive milestone, producing its 6 millionth drive unit as 2925 came to a close.

To celebrate the milestone, the Giga Nevada team gathered for a celebratory group photo. 

6 million drive units

The achievement was shared by the official Tesla Manufacturing account on social media platform X. “Congratulations to the Giga Nevada team for producing their 6 millionth Drive Unit!” Tesla wrote. 

The photo showed numerous factory workers assembled on the production floor, proudly holding golden balloons that spelled out “6000000″ in front of drive unit assembly stations. Elon Musk gave credit to the Giga Nevada team, writing, “Congrats on 6M drive units!” in a post on X.

Giga Nevada’s essential role

Giga Nevada produces drive units, battery packs, and energy products. The facility has been a cornerstone of Tesla’s scaling since opening, and it was the crucial facility that ultimately enabled Tesla to ramp the Model 3 and Model Y. Even today, it serves as Tesla’s core hub for battery and drivetrain components for vehicles that are produced in the United States.

Tesla’s Supercharger Network had its biggest year ever in 2025, delivering a record 6.7 TWh of electricity to vehicles worldwide. 

To celebrate its busy year, the official @TeslaCharging account shared an infographic showing the Supercharger Network’s growth from near-zero in 2012 to this year’s impressive milestone.

Record 6.7 TWh delivered in 2025

The bar chart shows steady Supercharger energy delivery increases since 2012. Based on the graphic, the Supercharger Network started small in the mid-2010s and accelerated sharply after 2019, when the Model 3 was going mainstream. 

Each year from 2020 onward showed significantly more energy delivery, with 2025’s four quarters combining for the highest total yet at 6.7 TWh.

This energy powered millions of charging sessions across Tesla’s growing fleet of vehicles worldwide. The network now exceeds 75,000 stalls globally, and it supports even non-Tesla vehicles across several key markets. This makes the Supercharger Network loved not just by Tesla owners but EV drivers as a whole.

Resilience after Supercharger team changes

2025’s record energy delivery comes despite earlier 2024 layoffs on the Supercharger team, which sparked concerns about the system’s expansion pace. Max de Zegher, Tesla Director of Charging North America, also highlighted that “Outside China, Superchargers delivered more energy than all other fast chargers combined.”

Longtime Tesla owner and FSD tester Whole Mars Catalog noted the achievement as proof of continued momentum post-layoffs. At the time of the Supercharger team’s layoffs in 2024, numerous critics were claiming that Elon Musk was halting the network’s expansion altogether, and that the team only remained because the adults in the room convinced the juvenile CEO to relent.

Such a scenario, at least based on the graphic posted by the Tesla Charging team on X, seems highly implausible.
