SpaceX rapidly shipping upgraded Raptor engines to Starbase

Published

SpaceX appears to have opened the floodgates and begun shipping upgraded ‘Raptor V2’ engines to Starbase en masse in preparation for crucial Starship and Super Heavy testing.

The first functional Raptor engine delivery in around half a year and the first Raptor V2 delivery ever appeared to arrive at Starbase on March 30th. About a month and a half prior, SpaceX brought an early Raptor V2 prototype damaged during testing to serve as a backdrop for CEO Elon Musk’s February 10th Starship presentation, marking the first time the public was allowed to see or photograph the engine up close.

Less than three months later, Raptor V2 engines that passed proof testing without damaging or destroying themselves have begun to rapidly pile up inside one of Starbase’s three main production tents.

Though Raptor V2 has plenty in common with its Raptor V1 and V1.5 predecessors and, for the most part, looks very similar, Musk has repeatedly stated that the engine represents a major evolution from past Raptors. Most importantly, Raptor V2 was designed to significantly cut production cost and time. To achieve that, almost every major component was either fully redesigned, tweaked, or refined in some way to make Raptor simpler and more compact.

One example is the decision to slash the number of flanges (mechanical joints) in the engine’s plumbing by replacing them with welds. Making plumbing more monolithic could remove dozens of parts, seals, and potential leak points and significantly speed up manufacturing at the cost of making it harder – if not impossible – for SpaceX to inspect and replace certain pipes or pipe sections in a modular manner.

That process was repeated throughout each Raptor system, resulting in an engine that looks more streamlined than earlier variants. As a result of its more refined design and improvements to other critical components, Musk says that even though Raptor V2 now costs about half as much to build as V1.5, it’s also “much more…reliable.”

Despite significantly improving Raptor’s reliability, simplicity, and cost, SpaceX also managed to boost its maximum thrust by almost 25%. Raptor V2 engines now “routinely” operate at record-breaking main combustion chamber pressures of 300+ bar (~4400 psi) and are able to produce up to 230 tons (~510,000 lbf) of thrust at sea level. The older Raptor V1.5 engines that flew on Starships SN8-SN11 and SN15 and were installed on Super Heavy Booster 4 and Ship 20 were designed to produce around 185 tons (~410,000 lbf) at 250 bar (~3600 psi).

Following the premature retirement of Super Heavy Booster 4 (B4), which was meant to help send Starship S20 to space on the rocket’s first orbital launch attempt, that orbital launch debut is now guaranteed to use a different booster and ship powered by Raptor V2 engines. Ship 24 is a strong candidate for the mission’s Starship, while it remains to be seen if SpaceX will fully repair and attempt to proceed with Booster 7 or if Booster 8 – which is almost complete – will take point.

Either way, the pair will need at least 39 qualified Raptor V2 engines to begin integrated testing, pass several major static fire milestones, and prepare for flight. Since SpaceX appeared to kick off Raptor V2 deliveries to Starbase on March 30th, a photo shared by Musk on April 26th revealed that the company has managed to deliver at least 18 of the upgraded engines in the last four weeks. At least one more engine was also delivered on April 28th.

That means that SpaceX already has enough engines to begin static fire tests with a full cluster of 13 central Raptors on Super Heavy B7 or B8. By the time Ship 24 is fully assembled, Booster 7 is repaired, or Booster 8 is completed, there’s a good chance that SpaceX will have all the engines it needs to fully outfit a Starship and Super Heavy pair – not quite by the end of April, as Musk predicted, but not far off.

Elon Musk reveals SpaceX’s target for Starship’s 10th launch

Elon Musk has revealed SpaceX’s target timeline for the next Starship launch, which will be the tenth in program history.

Elon Musk has revealed SpaceX’s target timeline for the next Starship launch, which will be the tenth in program history.

Musk says SpaceX is aiming for a timeline of roughly three weeks from now, which would come about ten weeks after the previous launch.

Coincidentally, it would bring the two launches 69 days apart, and if you know anything about Elon Musk, that would be an ideal timeline between two launches.

SpaceX is coming off a test flight in which it lost both the Super Heavy Booster and the Upper Stage in the previous launch. The Super Heavy Booster was lost six minutes and sixteen seconds into the flight, while SpaceX lost communication with the Ship at 46 minutes and 48 seconds.

Musk is aiming for the tenth test flight to take place in early August, he revealed on X:

This will be SpaceX’s fourth test flight of the Starship program in 2025, with each of the previous three flights bringing varying results.

IFT-7 in January brought SpaceX its second successful catch of the Super Heavy Booster in the chopstick arms of the launch tower. The ship was lost after exploding during its ascent over the Turks and Caicos Islands.

IFT-8 was on March 6, and SpaceX caught the booster once again, but the Upper Stage was once again lost.

The most recent flight, IFT-9, took place on May 27 and featured the first reused Super Heavy Booster. However, both the Booster and Upper Stage were lost.

The Federal Aviation Administration (FAA) hit SpaceX with a mishap investigation for Flight 9 on May 30.

Tesla CEO Elon Musk has confirmed that the company will roll out a new feature for in-car Grok as it is rolling out to vehicles for the first time.

Grok was just recently added as a feature to Tesla vehicles within the past week, but owners are already requesting some small changes to make it more convenient to use.

Tesla debuts hands-free Grok AI with update 2025.26: What you need to know

The first is already on the way, Musk confirmed, as WholeMarsBlog requested a simple, but useful feature for Grok as it is used within Tesla vehicles.

Whole Mars requested that “Hey Grok” be used as a wake word, automatically activating the AI assistant without having to touch any buttons. Musk confirmed it is already in development and on the way to vehicles:

This feature is incredibly similar to that of “Hey Siri” with iPhones and other iOS devices. The phone will recognize your voice and hear that prompt, automatically activating Siri. Apple’s assistant will then perform whatever task it is asked to perform. It’s a simple but effective performance feature.

Grok is already getting its first reviews from owners as it rolls out to owners for the first time. It is a long time coming, too. Tesla has been hinting that Grok would be enabled in the vehicles for a while now, and it just started its initial rollout last week.

Grok is available in vehicles with the AMD chip and requires Premium Connectivity or a WiFi connection to use.

Tesla reveals key detail of Supercharger Diner, but it’s bigger than you think

Tesla has finally released one key detail about the Supercharger Diner, and it is bigger than what it appears at face-value.

Tesla has revealed a key detail of its Supercharger Diner as its launch date appears to be nearing, based on what we are seeing at the site currently.

The Supercharger Diner is located on Santa Monica Boulevard in Los Angeles and was first proposed as an idea by CEO Elon Musk back in 2018. Musk envisioned a drive-in movie-style 1950s-inspired diner that would feature elements such as servers on roller skates, large movie screens, and a menu inspired by classic treats from several decades ago.

A project that first broke ground in 2023, the Supercharger Diner has been in development for over two years, as Tesla performed demolition work at the site back in February of that year.

It has slowly moved forward, and drone footage shot this week seems to show things are nearly up and running. Musk even mentioned that he had eaten at the Diner Supercharger this week.

There are still details that Tesla has yet to announce and confirm. The most important thing is regarding the menu that will be served at the diner.

Tesla has not hinted at what it will be making for patrons at the restaurant, but Musk commended the food and said the diner would be one of the coolest spots in LA.

However, we now have details on another important thing about the restaurant: the hours.

Images taken by Aaron Cash of ABetterTheater.com show the diner will be open 24/7, as it appears on the front doors of the diner:

At first thought, it seems this will operate like any other diner, as many are open for 24 hours a day. Diners typically serve large menus with numerous options, catering to the tastes and moods of anyone who walks in.

People of all walks of life eat at diners, as the food is typically affordable, tasty, and available at any hour to serve those who are night owls or those who work non-typical schedules.

However, Tesla is a bit different, and it seems that this new venture into food service could eventually transition from human servers and cooks to robots, most notably the company’s in-house project of Optimus.

It is something straight out of a Star Wars movie. I can think of Obi-Wan Kenobi visiting Dex in his diner in Attack of the Clones to figure out where a poison dart was sourced from:

Eventually, Optimus will likely be working as an employee in the Tesla Diner, and 24/7 operation will be performed by the humanoid robot that aims to eliminate trivial tasks from humans.
