SpaceX’s Elon Musk talks next goals for Falcon rocket reusability
CEO Elon Musk has reiterated that SpaceX is still pursuing a major rocket reuse milestone he originally set for the company several years ago and revealed that its Falcon rockets could ultimately soar far beyond it.
Musk has been talking publicly about reusable rockets for well over a decade but the first hard numbers linked to real hardware came with the debut of Falcon 9’s Block 5 upgrade in May 2018. In a conference call with reporters, Musk famously revealed that the Block 5 upgrade incorporated design changes that would ultimately allow SpaceX to reuse orbital-class Falcon boosters at least ten times each. An upper bound of 100+ flights per booster would also be possible with regular maintenance and part replacements every ten or so launches.
Since the upgrade’s May 11th, 2018 launch debut, Falcon 9 and Heavy Block 5 rockets have completed 37 launches – all successful – with only one in-flight anomaly, a March 2020 engine failure that prevented booster recovery but didn’t preclude mission success. Excluding three flawless Falcon Heavy launches, SpaceX’s 34 Falcon 9 Block 5 launches were collectively completed by 11 boosters – an average of >3 launches per rocket. In fewer words, SpaceX has accumulated a vast wealth of data with which it can judge the Block 5 design and CEO Elon Musk has some choice observations more than two years after his Block 5 press conference.
In the simplest possible terms, Musk’s August 19th comments strongly suggest that the Block 5 upgrade has more than met the goals laid out for it back in 2018.
The fact alone that the average Falcon 9 Block 5 booster (even including one expendable mission) has launched more than three times is a major credit to the design. At the same time, SpaceX flew the same booster for the sixth time just days ago and achieved the fifth launch of three separate Falcon 9 boosters between March and August of 2020.
Now, with all that experience in hand and a Falcon 9 Block 5 booster already 60% of the way to the ten-flight reuse milestone, Musk says that “100+ flights are possible” and that “there isn’t an obvious limit.” While “some parts will need to be replaced or upgraded” to achieve dozens or hundreds of booster reuses, Musk says that SpaceX “almost never need[s] to replace a whole [Merlin 1D] engine.
Given that a Falcon 9 booster’s nine M1D engines are likely the most difficult part of each rocket to quickly and safely reuse, it’s extremely easy to believe that individual boosters can launch dozens – if not hundreds – of times with just a small amount of regular maintenance and repairs. In that sense, SpaceX has effectively achieved Musk’s long-lived dream of building a rocket that is (more or less, at least) approaching the reusability of aircraft.
Of course, even 100-flight Falcon boosters would still be at least one or two orders of magnitude distant from most modern aircraft, but that would still be a vast improvement over any other launch vehicle in history (especially including the Space Shuttle).
Musk says that SpaceX is still actively pushing to fly a Falcon 9 booster ten times and Starlink missions – allowing the company to mitigate risk on its own launches – will leave plenty of opportunities. If SpaceX can fly Falcon 9 booster B1049 every 60 days on average, the company could hit that ten-flight milestone as early as Q2 2021.
The SpaceX CEO also responded to a classic head-in-the-sand claim from traditional aerospace companies like United Launch Alliance (ULA), refuting the theoretical supposition that booster reuse “doesn’t make sense” until ten-flight reuse is achieved. Instead, Musk says that SpaceX only needs to fly each booster three times to ensure that booster reuse is cheaper than just building new rockets.
In short, despite the ad hoc rationalizations competitors continue to use to excuse years of denial and laurel-resting, SpaceX is routinely reusing rockets, saving major resources by doing so, and has still just barely scratched the surface of what is ultimately possible.

Tesla Senior Vice President for Automotive Tom Zhu, a key executive behind the company’s success in China and Giga Texas, recently highlighted the “prime directive” of Full Self-Driving (FSD).
Zhu’s comments emphasize Tesla’s uncompromising focus on safety, which has made the company’s vehicles among the safest on the road.
Echoing Musk’s vision for safe autonomous driving
Zhu’s post quoted Musk’s statement from 2021, where the CEO reportedly stated that FSD must avoid accidents even if the most ridiculous events happened in the middle of the road. Zhu stated that beyond everything, Tesla’s systems like Autopilot and FSD are designed to keep passengers safe.
“Elon said it in 2021: “For self-driving, even if the road is painted completely wrong and a UFO lands in the middle of the road, the car still cannot crash and still needs to do the right thing. The prime directive for the autopilot system is: Don’t crash. That really overrides everything. No matter what the lines say or how the road is done, the thing that needs to happen is minimizing the probability of impact while getting you to your destination conveniently and comfortably,” Zhu stated.
“The prime directive, the absolute priority, is to minimize the probability of injury to yourself or to anyone on the road, to pedestrians, or anything like that. It can’t be dependent on the road markings being correct.”
Tesla leadership rallies behind global FSD rollout
Tom Zhu, who previously led Tesla China through its record-breaking growth phase, now oversees automotive operations worldwide. He has reportedly become a problem solver for Elon Musk over the years, with previous reports stating that he was brought in to help Giga Texas optimize its vehicle production ramp.
Zhu’s comments may sound ambitious, but FSD has proven that it values safety above all else over the years. This was highlighted recently in an incident in Australia, when a Model Y was hit by what could very well be a meteor. Despite the impact and part of its windshield melting, the vehicle was able to drive safely and keep its passengers safe.

Elon Musk’s biggest tech rival just canceled his Tesla Roadster
“I really was excited for the car! And I understand delays. But 7.5 years has felt like a long time to wait,” Altman said.
Elon Musk’s biggest tech rival just canceled his reservation for a Tesla Roadster, the supercar the company has been developing for nearly eight years.
Sam Altman, the CEO of OpenAI, announced on X on Thursday evening that he canceled his Tesla Roadster reservation, or at least is trying to:

Altman placed his Tesla Roadster reservation with a $50,000 deposit way back on July 11, 2018. However, he recently decided that he had waited long enough and decided to email the company to officially cancel the order.
“Hi, I’d like to cancel my reservation. Could you please refund me the $50k?” Altman emails to reservations@tesla.com.
He then received an immediate response, but not from Tesla. Instead, it was a bounce-back message from Google, stating that the message could not be delivered to the email because it was not active.
Altman then provided a reason for his cancellation, and it was not related to the intense rivalry he had with Elon Musk:
“I really was excited for the car! And I understand delays. But 7.5 years has felt like a long time to wait.”

Altman and Musk have a lengthy history with one another that dates back to 2015, when OpenAI was created. The feud has resulted in lawsuits over breaching founding agreements by prioritizing profits.
Musk has been especially critical in recent years because of Altman’s decision to turn OpenAI into a for-profit business that he says is “built on a lie.”
This year, Musk offered over $97 billion to buy OpenAI, and a judge blocked his request to stop the company from being converted into a for-profit in March.
OpenAI then countersued Musk in April, while xAI, Musk’s company, sued OpenAI for allegedly stealing secrets through poached employees in September.

Regarding the Roadster, Tesla has been developing it for several years and has delayed its release for five consecutive years. The company says it will have a demo of what it has changed since it was unveiled in 2017 later this year, but no date has been set quite yet.

Neuralink’s first human patient reflects on 21 months with brain implant “Eve”
He credited Neuralink and Elon Musk for giving him “the opportunity to be the first,” as the experience has been life-changing.
Nolan Arbaugh, the first person to receive Neuralink’s brain implant, shared his 21-month update this week, reflecting on how far he’s come since his groundbreaking surgery.
Arbaugh, who became paralyzed after a diving accident, stated that his Neuralink implant, which he fondly calls “Eve,” continues to transform his daily life.
Arbaugh celebrates Neuralink’s progress
In his post on X, Arbaugh revealed that his hands-on involvement with Neuralink has decreased as more participants have joined the program. “The team might call me to test something once in a blue moon,” he wrote, adding that he’s happy to see others experience the technology’s full potential, from operating robotic arms to typing on keyboards with thought alone.
He credited Neuralink and Elon Musk for giving him “the opportunity to be the first,” as the experience has been life-changing. Despite a recent pressure sore that temporarily kept him bedridden, Arbaugh noted that he is still very optimistic, describing his journey as one of resilience, faith, and gratitude. He also teased “big news” coming for his two-year update in early 2026.
Studies and a growing public speaking career
These days, Arbaugh stated that he is focused on his studies in neuroscience, taking full-semester courses in chemistry, biology, and pre-calculus while earning top grades. He credited “Eve” for making school possible again, as his current academic workload would have been “impossible without Neuralink.” Arbaugh stated that he has also begun building a speaking business after delivering a paid talk at Fortune’s Brainstorm Tech conference.
“At the beginning of September I attended the Fortune Brainstorm Tech conference in Park City, Utah, as a paid speaker. That sentence seemed like an impossibility two years ago. But it’s just the beginning. My business is built, my legal is near complete, I’m surrounding myself with a team of amazing folks, and I plan on speaking once or twice a month in the same fashion beginning as soon as January.
“Conferences, interviews, podcasts—you name it, and I want to be there spreading the word about how amazing this technology is, the growth it’s experiencing, the possibilities of the future, and how it has so deeply affected my life,” Arbaugh stated.
