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.

Tesla winter weather test: How long does it take to melt 8 inches of snow?

Published

In Pennsylvania, we got between 10 and 12 inches of snow over the weekend as a nasty Winter storm ripped through a large portion of the country, bringing snow to some areas and nasty ice storms to others.

I have had a Model Y Performance for the week courtesy of Tesla, which got the car to me last Monday. Today was my last full day with it before I take it back to my local showroom, and with all the accumulation on it, I decided to run a cool little experiment: How long would it take for Tesla’s Defrost feature to melt 8 inches of snow?

Tesla Model Y Performance set for new market entrance in Q1

Tesla’s Defrost feature is one of the best and most underrated that the car has in its arsenal. While every car out there has a defrost setting, Tesla’s can be activated through the Smartphone App and is one of the better-performing systems in my opinion.

It has come in handy a lot through the Fall and Winter, helping clear up my windshield more efficiently while also clearing up more of the front glass than other cars I’ve owned.

The test was simple: don’t touch any of the ice or snow with my ice scraper, and let the car do all the work, no matter how long it took. Of course, it would be quicker to just clear the ice off manually, but I really wanted to see how long it would take.

Observations

I started this test at around 10:30 a.m. It was still pretty cloudy and cold out, and I knew the latter portion of the test would get some help from the Sun as it was expected to come out around noon, maybe a little bit after.

I cranked it up and set my iPhone up on a tripod, and activated the Time Lapse feature in the Camera settings.

The rest of the test was sitting and waiting.

It didn’t take long to see some difference. In fact, by the 20-minute mark, there was some notable melting of snow and ice along the sides of the windshield near the A Pillar.

However, this test was not one that was “efficient” in any manner; it took about three hours and 40 minutes to get the snow to a point where I would feel comfortable driving out in public. In no way would I do this normally; I simply wanted to see how it would do with a massive accumulation of snow.

It did well, but in the future, I’ll stick to clearing it off manually and using the Defrost setting for clearing up some ice before the gym in the morning.

Tesla Robotaxi ride-hailing without a Safety Monitor proves to be difficult

Tesla Robotaxi ride-hailing without a Safety Monitor is proving to be a difficult task, according to some riders who made the journey to Austin to attempt to ride in one of its vehicles that has zero supervision.

Last week, Tesla officially removed Safety Monitors from some — not all — of its Robotaxi vehicles in Austin, Texas, answering skeptics who said the vehicles still needed supervision to operate safely and efficiently.

BREAKING: Tesla launches public Robotaxi rides in Austin with no Safety Monitor

Tesla aimed to remove Safety Monitors before the end of 2025, and it did, but only to company employees. It made the move last week to open the rides to the public, just a couple of weeks late to its original goal, but the accomplishment was impressive, nonetheless.

However, the small number of Robotaxis that are operating without Safety Monitors has proven difficult to hail for a ride. David Moss, who has gained notoriety recently as the person who has traveled over 10,000 miles in his Tesla on Full Self-Driving v14 without any interventions, made it to Austin last week.

He has tried to get a ride in a Safety Monitor-less Robotaxi for the better part of four days, and after 38 attempts, he still has yet to grab one:

Tesla said last week that it was rolling out a controlled test of the Safety Monitor-less Robotaxis. Ashok Elluswamy, who heads the AI program at Tesla, confirmed that the company was “starting with a few unsupervised vehicles mixed in with the broader Robotaxi fleet with Safety Monitors,” and that “the ratio will increase over time.”

This is a good strategy that prioritizes safety and keeps the company’s controlled rollout at the forefront of the Robotaxi rollout.

However, it will be interesting to see how quickly the company can scale these completely monitor-less rides. It has proven to be extremely difficult to get one, but that is understandable considering only a handful of the cars in the entire Austin fleet are operating with no supervision within the vehicle.

Tesla gives its biggest hint that Full Self-Driving in Europe is imminent

Tesla has given its biggest hint that Full Self-Driving in Europe is imminent, as a new feature seems to show that the company is preparing for frequent border crossings.

Tesla owner and influencer BLKMDL3, also known as Zack, recently took his Tesla to the border of California and Mexico at Tijuana, and at the international crossing, Full Self-Driving showed an interesting message: “Upcoming country border — FSD (Supervised) will become unavailable.”

Due to regulatory approvals, once a Tesla operating on Full Self-Driving enters a new country, it is required to comply with the laws and regulations that are applicable to that territory. Even if legal, it seems Tesla will shut off FSD temporarily, confirming it is in a location where operation is approved.

This is something that will be extremely important in Europe, as crossing borders there is like crossing states in the U.S.; it’s pretty frequent compared to life in America, Canada, and Mexico.

Tesla has been working to get FSD approved in Europe for several years, and it has been getting close to being able to offer it to owners on the continent. However, it is still working through a lot of the red tape that is necessary for European regulators to approve use of the system on their continent.

This feature seems to be one that would be extremely useful in Europe, considering the fact that crossing borders into other countries is much more frequent than here in the U.S., and would cater to an area where approvals would differ.

Tesla has been testing FSD in Spain, France, England, and other European countries, and plans to continue expanding this effort. European owners have been fighting for a very long time to utilize the functionality, but the red tape has been the biggest bottleneck in the process.
