SpaceX reinstalling 29 Raptor engines on first orbital-class Starship booster

Published

on

For the second time this month, SpaceX has begun installing 29 Raptor engines on Starship’s first orbital-class Super Heavy booster, potentially paving the way for several crucial milestones.

On August 1st, around the same time as SpaceX finished installing car-sized grid fins on a Super Heavy for the first time, the company began the process of installing multiple Raptor engines on the booster (#4) that might one day support Starship’s first orbital launch attempt. Not long after it began, it became clear that SpaceX was installing a full 29 Raptor engines on Booster 4 (B4) at a breakneck pace, and less than 24 hours later, all had been attached to Super Heavy’s thrust structure.

Barely a day later, Super Heavy Booster 4 was rolled to the orbital launch pad and installed on a massive ‘launch table’ that was itself installed just a few days prior after months of assembly. Four days after engine installation, Starship S20 and Booster 4 were briefly mated together, forming a full Starship stack – the tallest and most powerful rocket ever built – for about an hour. However, while it did serve as a useful learning experience and pathfinder operation, both stages were demated and returned to the factory soon after.

Since Booster 4’s later August 11th build site return, SpaceX teams have been hard at work fitting the massive 69m (225 ft) tall rocket booster with thousands of feet (if not miles) of secondary plumbing and power and avionics cables. That process effectively began with removing the Super Heavy’s 29 Raptor engines, which finished just a few days after its return to the high bay.

Now, just 12 days after Super Heavy Booster 4 arrived back at the high bay and 11 days after workers briskly removed its Raptors, SpaceX has begun the process of reinstalling those engines – albeit with several new entrants this time around. When SpaceX first fitted B4 with Raptors, it became clear that five or more of had never been tested, making the removal of some of the Super Heavy’s 29 engines more or less inevitable. Indeed, as expected, several new Raptors (engines that weren’t clearly installed the first time around) have joined around two dozen engines that were installed earlier this month.

Given that Booster 4 has already completed a range of fit checks, the implication is that SpaceX is now installing the 29 Raptor engines that will support the first static fire test campaign of a flightworthy Super Heavy. Of course, that testing (likely involving several different static fires of an increasing number of Raptors) could unearth issues or even damage some of those 29 Raptors, so it isn’t quite accurate to say that Booster 4 is being fitted with the engines that will help it carry Starship to orbit. Depending on the outcome of those tests, though, most could easily find themselves lifting off on Super Heavy B4 later this year.

For now, though, Super Heavy Booster 4’s next milestone will be its second trip from the build site to the launch pad. That could occur at any point in the next week or two and could find Booster 4 installed beside Ship 20 on the second of two suborbital test stands, though the Super Heavy may instead return to the orbital launch site.

SpaceX’s biggest test yet arrives this week and it’s not a rocket launch

Published

SpaceX will report second quarter results after the market closes on Tuesday, August 4, marking the first time the company has opened its books to the public since its record IPO in June. Management will host a live audio only webcast at 4:30 p.m. ET, streamed on X, with no dial in option.

The debut carries more weight than a typical first quarter as a public company. Two trading days after the release, on August 6, the first tranche of SpaceX’s lockup expires, freeing roughly 911.5 million insider and employee shares, worth well over $100 billion at current prices and the largest such release in Wall Street history. A second, larger tranche tied to the stock trading 30 percent above its $135 IPO price never triggered, since shares have spent most of July trading below that price.

Wall Street’s models point to revenue near $6.9 billion for the quarter, up sharply from the $4.69 billion SpaceX reported in the first quarter, with a narrower per share loss than the $1.27 posted three months earlier, according to estimates compiled by Motley Fool. Those numbers will be the first look at how SpaceX’s three segments, Starlink, launch and AI, are performing independently.

SpaceX scores another massive Pentagon deal to support military satellites

Investors heading into the call have a specific list of questions. How many net new Starlink subscribers did SpaceX add after ending March with 10.3 million, and is average revenue per user holding up as the service expands into lower income markets. How much of the AI segment’s revenue reflects contract signings with Anthropic, Google and Reflection AI this year, deals that combined could annualize to nearly $28 billion if fully ramped. Whether capital expenditures, which nearly doubled in the AI segment alone between 2024 and 2025, are still accelerating or starting to plateau. And whether management offers any forward guidance at all, something SpaceX has never done publicly.

The report will also land days after Elon Musk publicly denied a Wall Street Journal report describing internal planning to separate Tesla’s China business ahead of a potential Tesla-SpaceX merger. Whether Musk or SpaceX executives address that speculation on the call, even indirectly, maybe something investors will be listening for on Tuesday.

As Teslarati reported after Musk’s own warning to short sellers last week, the CEO has made clear he expects skeptics to be proven wrong over time. Tuesday will be the first chance for the numbers themselves to make that case.

SpaceX’s Starship just got filmed by its own cargo

SpaceX released new footage of Starship in space captured by the Starlink satellites it deployed.

SpaceX released a new video Friday evening showing Starship from an angle showcased by its own Starlink satellites, watching the rocket drift away in orbit.

The 65 second clip, posted on X, stitches together footage from four cameras mounted on a single Starlink V3 satellite. It opens with a close view of Starship’s 171 foot upper stage, still catching sunlight, then pulls back as the two spacecraft separate.

The footage comes from Starship’s 13th flight test, which launched July 24 from Starbase after a scrubbed attempt and an abort caused by an engine issue the week before. When Flight 13 finally flew, it carried the first batch of functional Starlink V3 satellites Starship has ever deployed, twenty of them, with six equipped with cameras meant to scan the ship’s heat shield during reentry.

Flight 13 checked most of its boxes. Starship deployed all 20 satellites, relit a Raptor engine in space, and splashed down softly in the Indian Ocean off Western Australia. Musk’s longer term plan calls for a Starlink V3 constellation of 100,000 satellites, according to a recent FCC filing, with Starship as the only vehicle capable of launching them at the volume that requires. Each Starship flight is designed to carry up to 60 V3 satellites once the vehicle reaches routine service, well beyond what Falcon 9 can carry in a single mission.

Starship is next expected to fly with an attempt at catching the ship itself with the launch tower’s mechanical arms, a maneuver SpaceX has so far reserved for the Super Heavy booster.

Tesla flexed the new features of the Model Y L with a dedicated media event at the company’s Diner on Santa Monica Boulevard in Los Angeles.

The Model Y L is the extended-wheelbase version of the all-electric crossover, which has been voted the best-selling car in the world on three occasions. The vehicle is already rolling off production lines at Gigafactory Texas, and first deliveries are slated to take place later this year.

Tesla brings Model Y L ‘Launch Series’ to the U.S. at $61,990

Teslarati was invited to the event, but due to some scheduling conflicts, we could not make it to Los Angeles. Instead, we will have our hands on a media unit sometime in August, so we’ll be able to spend some more extended time with the Model Y L.

However, plenty of those who made it to LA shared some cool features that set the Model Y L apart from the Model Y.

Multi-Row Climate Control

Tesla fitted the Model Y L with full climate control on all three rows on the front screen. It can be adjusted by selecting which row you’d like to modify on the right-hand side of the touch screen:

Better Rear Window Visibility

One of the strangest things about the Model Y, especially the Juniper iteration, is the rear window has extremely limited visibility when looking into the rearview mirror.

Tesla has improved upon this with the Model Y L:

PowerShare will be included

Model Y L will come with PowerShare in North America, with an 11.5kW output to your home. Tesla said it would require Powerwall 3 for operation.

Wireless Charging Pad

There has been some speculation that Tesla would upgrade the wireless charging pads in the United States, but this is not the case.

Tesla owner fixes common feature complaint with crafty DIY retrofit

Tesla confirmed that it does not come with the cooled pads as the Y L in China does. This is because North America has not adopted Qi charging yet.

Thermal Management Improvements

These improvements in the Model Y L were seen with thermal management:

  • Up to 15% faster cabin cooling
  • +23% thermal efficiency gained in hot weather, 7 miles of real-world range gained
  • 8x more solar energy reflection off of glass roof
  • 30% reduction in solar energy entering the cabin

Demand

Tesla said the Model Y L is almost sold out in the U.S. It comes with

  • 1 year of FSD Supervised
  • 1 year of Supercharging
  • 1 year of Premium Connectivity
  • Free exterior paint color, interior, and wheel option at no additional cost
