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 has entered an interesting situation with its Full Self-Driving suite in California, as the State’s Department of Motor Vehicles had adopted an order for a suspension of the company’s sales license, but it immediately put it on hold.

The company has been granted a reprieve as the DMV is giving Tesla an opportunity to “remedy the situation.” After the suspension was recommended for 30 days as a penalty, the DMV said it would give Tesla 90 days to allow the company to come into compliance.

The DMV is accusing Tesla of misleading consumers by using words like Autopilot and Full Self-Driving on its advanced driver assistance (ADAS) features.

The State’s DMV Director, Steve Gordon, said that he hoped “Tesla will find a way to get these misleading statements corrected.” However, Tesla responded to the story on Tuesday, stating that this was a “consumer protection” order for the company using the term Autopilot.

It said “not one single customer came forward to say there’s a problem.” It added that “sales in California will continue uninterrupted.”

Tesla has used the terms Autopilot and Full Self-Driving for years, but has added the term “(Supervised)” to the end of the FSD suite, hoping to remedy some of the potential issues that regulators in various areas might have with the labeling of the program.

It might not be too long before Tesla stops catching flak for using the Full Self-Driving name to describe its platform.

Tesla Robotaxi goes driverless as Musk confirms Safety Monitor removal testing

The Robotaxi suite has continued to improve, and this week, vehicles were spotted in Austin without any occupants. CEO Elon Musk would later confirm that Tesla had started testing driverless rides in Austin, hoping to launch rides without any supervision by the end of the year.

Tesla stock closes at all-time high on heels of Robotaxi progress

Tesla stock (NASDAQ: TSLA) closed at an all-time high on Tuesday, jumping over 3 percent during the day and finishing at $489.88.

The price beats the previous record close, which was $479.86.

Shares have had a crazy year, dipping more than 40 percent from the start of the year. The stock then started to recover once again around late April, when its price started to climb back up from the low $200 level.

This week, Tesla started to climb toward its highest levels ever, as it was revealed on Sunday that the company was testing driverless Robotaxis in Austin. The spike in value pushed the company’s valuation to $1.63 trillion.

Tesla Robotaxi goes driverless as Musk confirms Safety Monitor removal testing

It is the seventh-most valuable company on the market currently, trailing Nvidia, Apple, Alphabet (Google), Microsoft, Amazon, and Meta.

Shares closed up $14.57 today, up over 3 percent.

The stock has gone through a lot this year, as previously mentioned. Shares tumbled in Q1 due to CEO Elon Musk’s involvement with the Department of Government Efficiency (DOGE), which pulled his attention away from his companies and left a major overhang on their valuations.

However, things started to rebound halfway through the year, and as the government started to phase out the $7,500 tax credit, demand spiked as consumers tried to take advantage of it.

Q3 deliveries were the highest in company history, and Tesla responded to the loss of the tax credit with the launch of the Model 3 and Model Y Standard.

Additionally, analysts have announced high expectations this week for the company on Wall Street as Robotaxi continues to be the focus. With autonomy within Tesla’s sights, things are moving in the direction of Robotaxi being a major catalyst for growth on the Street in the coming year.

Tesla needs to come through on this one Robotaxi metric, analyst says

“We think the key focus from here will be how fast Tesla can scale driverless operations (including if Tesla’s approach to software/hardware allows it to scale significantly faster than competitors, as the company has argued), and on profitability.”

Tesla needs to come through on this one Robotaxi metric, Mark Delaney of Goldman Sachs says.

Tesla is in the process of rolling out its Robotaxi platform to areas outside of Austin and the California Bay Area. It has plans to launch in five additional cities, including Houston, Dallas, Miami, Las Vegas, and Phoenix.

However, the company’s expansion is not what the focus needs to be, according to Delaney. It’s the speed of deployment.

The analyst said:

“We think the key focus from here will be how fast Tesla can scale driverless operations (including if Tesla’s approach to software/hardware allows it to scale significantly faster than competitors, as the company has argued), and on profitability.”

Profitability will come as the Robotaxi fleet expands. Making that money will be dependent on when Tesla can initiate rides in more areas, giving more customers access to the program.

There are some additional things that the company needs to make happen ahead of the major Robotaxi expansion, one of those things is launching driverless rides in Austin, the first city in which it launched the program.

This week, Tesla started testing driverless Robotaxi rides in Austin, as two different Model Y units were spotted with no occupants, a huge step in the company’s plans for the ride-sharing platform.

Tesla Robotaxi goes driverless as Musk confirms Safety Monitor removal testing

CEO Elon Musk has been hoping to remove Safety Monitors from Robotaxis in Austin for several months, first mentioning the plan to have them out by the end of 2025 in September. He confirmed on Sunday that Tesla had officially removed vehicle occupants and started testing truly unsupervised rides.

Although Safety Monitors in Austin have been sitting in the passenger’s seat, they have still had the ability to override things in case of an emergency. After all, the ultimate goal was safety and avoiding any accidents or injuries.

Goldman Sachs reiterated its ‘Neutral’ rating and its $400 price target. Delaney said, “Tesla is making progress with its autonomous technology,” and recent developments make it evident that this is true.
