For the first time ever, SpaceX has successfully launched and landed the same Falcon 9 booster on four separate orbital-class missions, pushing the rocket’s Block 5 upgrade one step closer to realizing its ambitious design goals.

After an unprecedented lull of more than three months between launches, SpaceX has successfully returned to flight with its internal Starlink-1 mission, simultaneously crossing off multiple rocket reusability milestones. In terms of value added, Falcon 9 booster B1048’s reflight was the most important non-satellite achievement of the mission.

Impressively, B1048 has now successfully launched and landed on four separate occasions, a first for all Falcon 9 or Heavy boosters. Some nine minutes after lifting off from Cape Canaveral, Florida’s LC-40 launch pad, B1048 came to a gentle, near-bullseye halt aboard drone ship Of Course I Still Love You (OCISLY), stationed some 630 km (340 mi) northeast of the Florida coast.

With the successful completion of Starlink-1, B1048 alone has now collectively supported the launch of more than 35 metric tons (77,000 lb) into Earth orbit, as well as the first attempted (but sadly unsuccessful) commercial Moon landing attempt as part of its third launch in February 2019. This particular tidbit is noteworthy because it likely makes B1048 the first Falcon 9 booster to help orbit more than twice the payload mass it would otherwise be capable of launching in a single mission, an impressive reminder of the game-changing success of SpaceX’s reusable rocketry development.

Even then, B1049 is likely close on B1048’s heels – if not already ahead of the booster – in terms of the mass of satellites it has singlehandedly helped to place in orbit.

Aside from Falcon 9 B1048’s historic fourth launch and landing, Starlink-1 also marked the first time SpaceX has launched a flight-proven payload fairing, a huge step towards ensuring that nearly all future Falcon launches are up to 80% flight-proven and 80% reusable. Starlink-1’s payload fairing previously flew on Falcon Heavy Block 5’s Arabsat 6A launch debut back in April 2019, essentially a worst-case scenario for fairing reuse.

That successful reuse in spite of the fairing’s exceptionally extreme launch and recovery conditions suggests that almost any fairing recovered in the future will capable of at least one reuse, be it on internal Starlink missions if not customer launches. CEO Elon Musk has previously indicated that Falcon 9 (and Heavy) fairings represent approximately 10% of the cost of Falcon 9 launches, meaning that each set of halves has a price tag of roughly $6 million. Additionally, it’s believed that Falcon fairing production has some of the longest lead-time aspects of any aspect of SpaceX rocket manufacturing, to the point that fairings could easily become a bottleneck for launch cadence without expensive production facility upgrades.

Instead, SpaceX may have chosen to spend a similar amount of time and money making Falcon fairings routinely recoverable and reusable. That program crossed a turning point in June and August 2019, when fairing recovery ship GO Ms. Tree (formerly Mr. Steven) successfully caught two fairing halves in a row, unequivocally proving that the challenging catches are repeatable. Three months later, November 11th’s Starlink-1 launch has also proven that fairings can be reused even without a successful catch, meaning that it will likely be far easier and far more viable to reuse fairings that have been saved from ocean baths.

Unfortunately, SpaceX had to call off an attempted dual recovery of both fairing halves and GO Ms. Chief’s first operational catch attempt due to high seas in the recovery area. Prior to her remaining, similar sea conditions destroyed and broke off two of Mr. Steven’s arms while traveling to the recovery area, and SpaceX has clearly learned from that experience.

Tesla releases cryptic teaser for something massive and it’s coming this week

On Sunday morning, Tesla released a nine-second teaser video of what appears to be either a vehicle wheel, fan, or some sort of propeller, but there are no real clues as to what it could be exactly.

Tesla has released a cryptic teaser for something massive, and it will release details on it this week. With many different projects in the works, there is a lot of speculation going on about what it could potentially be, but we have a few ideas.

On Sunday morning, Tesla released a nine-second teaser video of what appears to be either a vehicle wheel, fan, or some sort of propeller, but there are no real clues as to what it could be exactly.

It then ends with “10/7,” meaning it will announce something on October 7, which is this Tuesday:

Given that Tesla has been working on a handful of pretty notable projects that are set for unveiling at the end of this year, and there are some clues that seem to point in their direction with this short teaser video.

There are two projects that come to mind almost immediately: the Tesla Roadster is one, and the “E41” or affordable model is the other. Here’s what we know about both:

Tesla Roadster Demo Event

Tesla said earlier this year that it would have a demo event for the Roadster to unveil some new technologies and show off what it has been working on over the past few years.

There have been a lot of crazy things in the works for the Roadster, including a SpaceX package that would use cold-gas thrusters for an insane 1.1-second 0-60 MPH acceleration rate. This package was also supposed to help it hover, something CEO Elon Musk has teased for the past few years.

The Roadster was ready for release earlier this year, but after Chief Designer Franz von Holzhausen and VP of Powertrain Lars Moravy showed Musk what they had come up with, he wanted more.

Moravy said on the Ride the Lightning podcast earlier this year:

“What we had come up with exceeded what we originally planned. So, Elon was like, ‘Wow, great. Let’s do more!'”

The Roadster event was coined as “the most epic demo,” and since it was planned for the end of 2025, it is totally feasible to believe this could be it.

Tesla ‘E41’ Affordable Model

Some believe the teaser could be the official launch of Tesla’s affordable model, which Musk said earlier this year is simply a stripped down Model Y.

There have been some sightings of this vehicle in the past few weeks, including one on Friday that showed the vehicle completely uncovered for the first time:

The launch of the affordable model makes sense, especially from a timing perspective. With the $7,500 EV tax credit officially coming to a close on September 30, many are wondering how Tesla will spark growth in its deliveries. A more affordable EV would be the perfect response, and it is something that Tesla has been working on for some time.

Other Potential Ideas

There are some pretty interesting ideas as to what the teaser could be apart from the Roadster or affordable model. Some believe it could be a cooling fan for a GPU cluster, which would make sense considering Tesla’s prowess in data.

Grok also made an interesting guess, stating it could be a propeller for a secret air taxi Tesla is developing. This seems sort of our of left field.

We do know Tesla hosted a handful of influencers at Gigafactory Texas this past week, so whatever the company showed them is likely what will be unveiled on Tuesday.

Tesla Optimus is learning martial arts, a new video released by CEO Elon Musk shows, a crazy development and advancement in the robotics project the company has been working on for a few years.

Optimus has been a major focus of Tesla for the past several years, especially as Musk has said he believes it will be the biggest product of all time and could be the biggest contributor to the company’s valuation.

For the past few months, Tesla has been refining its capabilities and making some serious progress on what Optimus is capable of. This morning, Musk released a new video showing Optimus learning Kung Fu, perhaps its most impressive feat yet:

The video shows Optimus working with a Kung Fu teacher, known as a Shifu, going through what appears to be some sort of routine of combinations. It’s quite impressive to see the fluidity of the movements and Optimus’s ability to keep up with Shifu.

Tesla has been “working hard” to scale Optimus production, Musk said last week, a project that has obviously confronted both AI and manufacturing teams with a variety of challenges.

The plan is to have an annual production run-rate of one million units by 2030, and there were plans to build 5,000 units this year.

Elon Musk gives update on Tesla Optimus progress

Musk still believes Optimus will make up roughly 80 percent of Tesla’s value. In January, he said it would be “overwhelmingly the value of the company.”

Tesla plans to launch the Gen 3 version of Optimus soon, and although a video of a new-look prototype was released by Marc Benioff, the CEO of Salesforce, the company’s frontman stated that this was not what the next-generation prototype would look like.

Elon Musk confirms Tesla has never shown Optimus V3 design yet

This video seems to show there is still significant progress being made on the Optimus project, and it will be perhaps one of the most impressive humanoid robots available to consumers in the coming years.

Tesla Full Self-Driving v14 gets new release date, Elon Musk details

“Last minute bug cropped up with V14. Released is pushed to Monday, but that gives us time to add a few more features.”

Tesla’s Full Self-Driving version 14 has gotten a new release date after new details from CEO Elon Musk opened up some new perspectives on the suite.

Originally slated for an “early wide release” of v14 this past week, then a launch of v14.1 and v14.2 this week and next week, respectively, delays arose after Tesla’s Autopilot team found some issues within the software.

Tesla FSD V14 set for early wide release next week: Elon Musk

Musk detailed on X this morning that a “last minute bug” appeared before release, which has now pushed FSD v14’s release back to this Monday:

Musk also said the delay would give Tesla the ability to “add a few more features,” which seems like an added advantage, although he did not provide any additional details on what these features could be.

In classic Musk fashion, he has teased the capabilities of this version of the FSD suite since it became public knowledge that Tesla was working on it. He said that it is the second most important update for the AI/Autopilot team since FSD v12.

V14 will have a parameter count that is ten times what previous iterations were, which should provide more accuracy and a more human-like operation.

Musk has said v14 “feels alive” and has used the word “sentient” to describe its performance. The goal with the new FSD rollouts is to eliminate as many interventions as possible, making it as close to human driving as possible.
