SpaceX Falcon 9 rocket breaks payload mass record with repaired booster

(SpaceX)

Published

SpaceX has set a new record for the heaviest payload launched on a Falcon 9 rocket as part of a routine Starlink satellite launch.

Simultaneously, the rocket responsible for setting that new record launched with a reusable booster that was last spotted clinging to life – engines heavily damaged – on the deck of a SpaceX drone ship eight months prior. At the time, it wasn’t clear if the Falcon 9 booster – theoretically capable of supporting at least 12-14 more launches – would be able to recover from the damage and fly again.

It’s now clear that the booster suffered no major invisible damage, ultimately allowing SpaceX to complete repairs and return the rocket to service at the cost of a lengthy delay.

According to spaceflight writer Alejandro Alcantarilla Romero, one additional cost – at minimum – was a full set of new Merlin 1D engines. Sometime shortly after Falcon 9 B1069’s flawless December 2021 launch and landing debut, a robotic helper known as Octagrabber most likely lost its grip on the booster while attempting to secure it. Likely already in high seas, the conditions prevented SpaceX workers from safely boarding the ship and manually securing the booster, which was then free to slide about its tilting deck.

Alternatively, it’s possible that Octagrabber successfully secured the booster but was then subjected to truly awful sea conditions. Designed to passively hold boosters to the deck with its sheer weight, even the tank-like robot wouldn’t be able to save a booster if a storm caught the drone ship off guard and the waves were high enough.

Either way, B1069 returned to port pressed against the lip of drone ship Just Read The Instructions’ (JRTI) deck, leaning hard to port. Worse, each of its nine fragile Merlin 1D engine nozzles had been crushed like tinfoil against Octagrabber, damaging them well beyond repair. While there’s a chance that SpaceX was or will be able to salvage the parts of B1069’s original M1D engines above their bell nozzles, it’s little surprise that the company had to fully replace those engines before the booster could fly again.

The damage B1069 suffered on its first launch makes it even more impressive that SpaceX attempted to break Falcon 9’s payload record with its return to flight, suggesting that the company was extremely confident in its repairs.

SpaceX confirmed that Falcon 9 broke the record with its launch of 54 Starlink V1.5 satellites at the end of its hosted webcast, revealing that the rocket launched 16.7 metric tons (~36,800 lb) to Low Earth Orbit (LEO). The last confirmed record – claimed by CEO Elon Musk – was 16.25 tons spread over 53 Starlink V1.5 satellites, which doesn’t entirely add up unless SpaceX added several kilograms to the mass of each satellite between March and August 2022.

Assuming that both numbers are comparable, a roughly 3% improvement is far from an earth-shaking or surprising step forward for SpaceX, a company, renowned for relentless iterative improvement. What is impressive, however, is that SpaceX pushed the envelope while Falcon 9 is both fast approaching its 150th consecutively successful launch and the only rocket currently certified to launch multiple NASA astronauts to the International Space Station. SpaceX’s fifth operational NASA astronaut launch (Crew-5) is scheduled as early as October 3rd. If SpaceX pushing the envelope on Starlink 4-23 had somehow caused the launch to fail, all Falcon 9 rockets would have likely been grounded for months, almost certainly delaying Crew-5 and throwing NASA’s ISS program into chaos.

Given how successful and reliable Falcon 9 already is, it would be hard to blame SpaceX if it decided to freeze the program and avoid additional changes, even if those changes could slightly improve the rocket’s performance. Instead, the company somehow manages to continue upgrading Falcon 9’s performance without obviously impacting its reliability or incurring the wrath of its strictest US government customers. Even Falcon landings, once considered a secondary objective that could be allowed to fail, haven’t suffered. Starlink 4-23 marked SpaceX’s 64th consecutively successful booster landing.

Up next, SpaceX is scheduled to launch Starlink 3-4 no earlier than (NET) August 31st, Starlink 4-20 NET September 4th, and Starlink 4-2 NET September 7th.

Rivian unveils self-driving chip and autonomy plans to compete with Tesla

Rivian, a mainstay in the world of electric vehicle startups, said it plans to roll out an Autonomy+ subscription and one-time purchase program, priced at $49.99 per month and $2,500 up front, respectively, for access to its self-driving suite.

Rivian unveiled its self-driving chip and autonomy plans to compete with Tesla and others at its AI and Autonomy Day on Thursday in Palo Alto, California.

Rivian, a mainstay in the world of electric vehicle startups, said it plans to roll out an Autonomy+ subscription and one-time purchase program, priced at $49.99 per month and $2,500 up front, respectively, for access to its self-driving suite.

CEO RJ Scaringe said it will learn and become more confident and robust as more miles are driven and it gathers more data. This is what Tesla uses through a neural network, as it uses deep learning to improve with every mile traveled.

He said:

“I couldn’t be more excited for the work our teams are driving in autonomy and AI. Our updated hardware platform, which includes our in-house 1600 sparse TOPS inference chip, will enable us to achieve dramatic progress in self-driving to ultimately deliver on our goal of delivering L4. This represents an inflection point for the ownership experience – ultimately being able to give customers their time back when in the car.”

At first, Rivian plans to offer the service to personally-owned vehicles, and not operate as a ride-hailing service. However, ride-sharing is in the plans for the future, he said:

“While our initial focus will be on personally owned vehicles, which today represent a vast majority of the miles to the United States, this also enables us to pursue opportunities in the rideshare space.”

The Hardware

Rivian is not using a vision-only approach as Tesla does, and instead will rely on 11 cameras, five radar sensors, and a single LiDAR that will face forward.

It is also developing a chip in-house, which will be manufactured by TSMC, a supplier of Tesla’s as well. The chip will be known as RAP1 and will be about 50 times as powerful as the chip that is currently in Rivian vehicles. It will also do more than 800 trillion calculations every second.

RAP1 powers the Autonomy Compute Module 3, known as ACM3, which is Rivian’s third-generation autonomy computer.

ACM3 specs include:

  • 1600 sparse INT8 TOPS (Trillion Operations Per Second).
  • The processing power of 5 billion pixels per second.
  • RAP1 features RivLink, a low-latency interconnect technology allowing chips to be connected to multiply processing power, making it inherently extensible.
  • RAP1 is enabled by an in-house developed AI compiler and platform software

As far as LiDAR, Rivian plans to use it in forthcoming R2 cars to enable SAE Level 4 automated driving, which would allow people to sit in the back and, according to the agency’s ratings, “will not require you to take over driving.”

More Details

Rivian said it will also roll out advancements to the second-generation R1 vehicles in the near term with the addition of UHF, or Universal Hands-Free, which will be available on over 3.5 million miles of roadway in the U.S. and Canada.

Rivian will now join the competitive ranks with Tesla, Waymo, Zoox, and others, who are all in the race for autonomy.

Tesla owners in California, Oregon, and Arizona can now use Lemonade Insurance, the firm that recently said it could cover Full Self-Driving miles for “almost free.”

Lemonade, which offered the new service through its app, has three distinct advantages, it says:

  • Direct Connection for no telematics device needed
  • Better customer service
  • Smarter pricing

The company is known for offering unique, fee-based insurance rates through AI, and instead of keeping unclaimed premiums, it offers coverage through a flat free upfront. The leftover funds are donated to charities by its policyholders.

On Thursday, it announced that cars in three states would be able to be connected directly to the car through its smartphone app, enabling easier access to insurance factors through telematics:

Tesla recently was offered “almost free” coverage for Full Self-Driving by Lemonade’s Shai Wininger, President and Co-founder, who said it would be “happy to explore insuring Tesla FSD miles for (almost) free.”

The strategy would be one of the most unique, as it would provide Tesla drivers with stable, accurate, and consistent insurance rates, while also incentivizing owners to utilize Full Self-Driving for their travel miles.

Tesla Full Self-Driving gets an offer to be insured for ‘almost free’

This would make FSD more cost-effective for owners and contribute to the company’s data collection efforts.

Data also backs Tesla Full Self-Driving’s advantages as a safety net for drivers. Recent figures indicate it was nine times less likely to be in an accident compared to the national average, registering an accident every 6.36 million miles. The NHTSA says a crash occurs approximately every 702,000 miles.

Tesla also offers its own in-house insurance program, which is currently offered in twelve states so far. The company is attempting to enter more areas of the U.S., with recent filings indicating the company wants to enter Florida and offer insurance to drivers in that state.

Tesla Model Y gets hefty discounts and more in final sales push

Tesla Model Y configurations are getting hefty discounts and more benefits as the company is in the phase of its final sales push for the year.

Tesla is offering up to $1,500 off new Model Y Standard trims that are available in inventory in the United States. Additionally, Tesla is giving up to $2,000 off the Premium trims of the Model Y. There is also one free upgrade included, such as a paint color or interior color, at no additional charge.

Tesla is hoping to bolster a relatively strong performance through the first three quarters of the year, with over 1.2 million cars delivered through the first three quarters.

This is about four percent under what the company reported through the same time period last year, as it was about 75,000 vehicles ahead in 2024.

However, Q3 was the company’s best quarterly performance of all time, and it surged because of the loss of the $7,500 EV tax credit, which was eliminated in September. The imminent removal of the credit led to many buyers flocking to Tesla showrooms to take advantage of the discount, which led to a strong quarter for the company.

2024 was the first year in the 2020s when Tesla did not experience a year-over-year delivery growth, as it saw a 1 percent slide from 2023. The previous years saw huge growth, with the biggest coming from 2020 to 2021, when Tesla had an 87 percent delivery growth.

This year, it is expected to be a second consecutive slide, with a drop of potentially 8 percent, if it manages to deliver 1.65 million cars, which is where Grok projects the automaker to end up.

Tesla will likely return to its annual growth rate in the coming years, but the focus is becoming less about delivery figures and more about autonomy, a major contributor to the company’s valuation. As AI continues to become more refined, Tesla will apply these principles to its Full Self-Driving efforts, as well as the Optimus humanoid robot project.

Will Tesla thrive without the EV tax credit? Five reasons why they might

These discounts should help incentivize some buyers to pull the trigger on a vehicle before the year ends. It will also be interesting to see if the adjusted EV tax credit rules, which allowed deliveries to occur after the September 30 cutoff date, along with these discounts, will have a positive impact.
