SpaceX expends Falcon 9 booster for the first time in almost three years

Published

on

For the first time since January 2020, SpaceX has intentionally expended a Falcon 9 booster instead of attempting to recover the rocket at sea or on land.

Weighing around 6.6 tons (~14,600 lb) at liftoff, the rare mission sent Intelsat’s twin Maxar-built Galaxy 31 and 32 communications satellites to a high geostationary transfer orbit (GTO) that will allow them to start operating more quickly than a standard GTO would. To launch such a heavy payload to such a high ‘supersynchronous’ transfer orbit, SpaceX – at Intelsat’s request and for a fee – removed all landing-related hardware from Falcon 9 and did not attempt to recover the first stage.

Instead, the rocket put all the propellant that would have otherwise been saved for recovery into its first and only burn, reaching as high a speed as possible before separating from the second stage. Flying for the 14th time since its March 2019 debut, Falcon 9 booster B1051 didn’t perform a controlled flip or attempt to land on a SpaceX drone ship. It’s more likely that the few-dozen-ton rocket – now drained of propellant – reentered Earth’s atmosphere with no control at a speed of roughly 2.7 kilometers per second (~6000 mph), broke apart when it slammed into that atmospheric ‘wall,’ and crashed into the Atlantic Ocean as a cloud of debris.

Having already flown 13 times before its 14th and final mission, it’s safe to say that booster B1051 earned its permanent retirement as an artificial reef. The mission marked the first time a Falcon 9 booster was intentionally discarded since January 2020, when the first Falcon 9 Block 5 booster – B1046 – was destroyed as part of an intentional In-Flight Abort test of SpaceX’s Crew Dragon spacecraft.

Like B1046, B1051 was another fairly new Falcon 9 Block 5 booster. It’s no coincidence that most of the first five or so boosters have been or will be intentionally expended. B1047 was first in August 2019, followed by B1046 five months later, and B1051 in November 2022. B1048 and B1050 both suffered in-flight anomalies that – while they didn’t impact the success of their primary missions – resulted in failed landing attempts. After B1051’s demise, only B1049 remains. Next Spaceflight reports that SpaceX will also intentionally expend that booster after its 11th launch, which will send the Eutelsat 10B communications satellite to a different geostationary transfer orbit as early as this month..

While SpaceX likely charged its customers a healthy fee to expend B1049 and B1051, the company is likely not complaining about an opportunity to refine its fleet of Falcon boosters. Though no new variant has been officially introduced, SpaceX has learned more about the design over the years, and newer Falcon Block 5 boosters include improvements that make them easier and cheaper to operate and reuse. It’s also added four new Falcon 9 boosters to the fleet in less than a year, easing the burden created by expending two older but flightworthy boosters weeks apart.

Once B1049 is gone, that fleet will still have one unflown Falcon 9 booster, four unflown Falcon Heavy boosters, ten flown Falcon 9 boosters, and four flown Falcon Heavy side boosters – the latter of which can potentially be converted into Falcon 9 boosters during Falcon Heavy lulls. B1051 was the third Falcon 9 booster to complete 14 launches, meaning that SpaceX has gotten so good at routine reusability that it can safely assume that each new Falcon 9 Falcon Heavy side booster can fulfill the roles of more than a dozen expendable boosters.

Ultimately, B1051’s sacrifice left Falcon 9’s expendable upper stage with enough performance to boost Galaxy 31 and 32 into a supersynchronous orbit with an apogee more than 58,400 kilometers (~36,300 miles) above Earth’s surface – almost 1.5 times its circumference. Just last month, two recoverable Falcon 9 boosters helped launch a pair of smaller 4.5-ton (~10,000 lb) satellites to almost identical orbits (~57,500 km vs. ~58,400 km). Expending Falcon 9’s booster thus allowed SpaceX to launch almost 50% more payload to a similar supersynchronous GTO, demonstrating the substantial toll booster reuse incurs on launches to higher orbits.

Galaxy 31/32 was SpaceX’s 52nd launch this year and hit a target set by CEO Elon Musk in January. Musk later raised his goal to 60 launches, but SpaceX has managed an average of one Falcon launch every six days for nearly 12 months and has a strong shot at completing another eight launches before the end of the year.

SpaceX’s Gwynne Shotwell just made a quiet gesture toward Tesla

SpaceX president Gwynne Shotwell quietly followed Tesla on X, and merger watchers noticed right away.

Published

SpaceX President and COO Gwynne Shotwell has started following Tesla’s official account on X, a small change that landed in the middle of a very loud merger conversation. Whole Mars Catalog joked about it on Sunday.

A follow is not an announcement, and neither company has said anything about a deal. What gives the moment weight is the timing. Barclays analyst Dan Levy has told clients that an agreement could come before Tesla’s annual meeting, which must be held by December 6, with SpaceX as the buyer in an all stock deal, as we reported after the Roadster unveiling. Wedbush’s Dan Ives has stuck with a 2027 timeline.

Shotwell is the executive most worth watching if the two companies do move closer. When Musk was asked at the All In Summit why Tesla and SpaceX remain separate, Shotwell sat next to him and said SpaceX personnel had already moved into xAI to fill leadership and engineering gaps. The businesses were integrating “faster than I thought,” she said, though “not fully integrated yet.” Her responsibilities have also grown since SpaceX absorbed xAI, and she now oversees operations that include Grok and the company’s AI compute buildout.

The financial links are already there. Tesla’s $2 billion xAI investment turned into a stake of less than one percent in SpaceX, the two share the Terafab chip project in Austin, and Musk exercised his 2018 Tesla options a week after SpaceX began trading, a sequence analysts flagged as giving SpaceX public shares to use in a deal. Musk holds about 20 percent of Tesla and controls 85.1 percent of SpaceX’s voting power, according to our earlier breakdown.

The next test is close at hand. SpaceX reports its second earnings as a public company on Tuesday after the close, and Tesla follows on Wednesday. Musk told analysts in July that “we can’t talk about combining companies and that kind of thing on an earnings call,” so a direct answer is unlikely from either stage. Tesla shareholders can still submit and vote on questions through the Say portal until 4 p.m. EDT on Monday, and the merger is a recurring theme in the queue.

Tesla Roadster owners to get “Flying Stunt Mode” and looping track access

Musk says Roadster owners can command the unveiling stunts autonomously, with a Texas looping track.

Elon Musk says owners of the new Tesla Roadster will be able to ask the car to perform the stunts Tesla showed at its unveiling, with the car doing the driving itself. Musk made the comment Saturday in a reply on X to tech blogger Robert Scoble, and he added a promise of a looping track at Tesla’s Texas headquarters.

Scoble had argued that the person in the Roadster is not really driving it. In his description, the driver operates a computer that tells another computer what to do, with steering, braking and acceleration all handled by wire. Musk answered, “True. You will be able to ask the Roadster to perform any of the tricks shown autonomously, as it will be sentient. Also, we will have a wild looping track (crazier even than Hot Wheels) at our Texas HQ where you can test out your Roadster.”

At the October 15 event outside Waco, the car drove up a curved ramp until it was upside down, flew off on cold gas thrusters, flipped and landed. It also hovered over a Cybercab, Cybertruck, Semi, Model Y and Model 3 while moving. As we noted in our breakdown of the three Roadster configurations, Musk said at the event that the car “literally is just going to puff itself up” to perform the maneuvers whenever an owner wants. Saturday’s reply adds that the car would run them on its own.

Tesla has described some of the hardware that would make that possible. The Roadster uses steer by wire with a yoke, and its cold gas thrusters rely on electric actuators for small adjustments in flight. A fan system under the car creates suction, which Tesla says is strong enough to hold it upside down, a setup we covered in our look at the Roadster’s fan system and thrusters.

Musk did not say when an autonomous stunt feature might arrive, how it would work, or what he means by sentient. He also gave no size, location or opening date for the Texas track. Production is planned for Giga Texas in 2027 or 2028, and Tesla says the car is not approved for public road use. The Rocket version, the one built to fly, is invite only.

The comment follows a week of Musk teasing the event, including his claim that the demo would be a banger, which we covered before the stream. Tesla reports third quarter earnings on October 21, and shareholders can submit and vote on questions through the Say portal until 4 p.m. EDT on October 20, according to our earnings Q&A preview. A question about autonomous Roadster stunts and the Texas track would be a quick way to get specifics from management.

How to use Grok Bot to block spam calls and texts

Musk told users to ask Grok Bot to scrub their phone numbers from spam lists.

Elon Musk has a new use case for Grok Bot, and it is the spam call. On Thursday he replied to an X user named Arash with a short instruction: “Ask your @Grok @Bot to remove your phone number from spam call & text lists!” Arash had said he got tired of the calls, had an AI bot find his number on listing sites and file removal requests, and packaged the process as a free skill for others.

The skill is called Spam-Call Scrubber, which is described to find a phone number on people search sites and data brokers, submits the opt outs, completes the confirmation emails those sites send back, and rechecks on a schedule the user picks. Using it requires the Grok Bot app. The pitch is time saved, since most broker opt outs sit behind separate forms on separate sites.



Musk said Grok Bot now gives each bot its own email address, and that it can detect scam emails. On Thursday he also said SpaceX would make users whole if the bot botches a purchase or leaks a card, then told users to shop away from Amazon after the retailer blocked the agent, as Teslarati reported. The terms of service we reviewed at the time put responsibility for what an agent does on the user.

For Tesla owners, Grok Bot is not just a phone app. Tesla brought Grok Bot into its vehicles on September 22, and we argued earlier this week that the Cybercab’s real advantage may be the errands it runs during a ride. Every Cybercab and the rest of the Model Y Robotaxi fleet has it enabled. The more routine tasks like this one become, the more a rider has reason to hand over something personal in the back seat.

The new Spam-Call Scrubber skill can be downloaded for free and works on sites that honor removal requests, while noting that listings can reappear, and illegal robocallers do not check any registry. Whether Spam-Call Scrubber cuts anyone’s call volume is something the first wave of users will find out, and Musk’s endorsement guarantees that wave is coming.
