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 begins validating Robotaxi in a new area, hinting at expansion

Tesla is validating Robotaxi in a new area, and as the company has continued to gain some additional permissions to begin testing in new states, it seems its Full Self-Driving-based ride-hailing project is moving toward a larger footprint.

Two Robotaxi units with LiDAR validation equipment were spotted in Gilbert, Arizona, recently, showing that Tesla is aiming to launch its ride-hailing service in the state soon:

Another unit was spotted in Tempe, Arizona:

These types of validation vehicles have been spotted in several areas ahead of their launch as a public ride-hailing service for passengers. Tesla first launched Robotaxi in Austin, Texas, back in late June, and since then, it has expanded to the Bay Area of California.

However, Tesla has continued to attempt to expand Robotaxi to other areas as well, including Nevada and Arizona. It has also been working toward approvals in other states based on job postings, as Tesla is hiring for Autopilot Vehicle Operators in New York and Florida, as well.

The expansion of the Robotaxi ride-hailing service has been an effort that Tesla has been spending a lot of time on over the past few months. CEO Elon Musk said the expansion aims to bring Robotaxi to at least half of the U.S. population by the end of the year, but there is still plenty of work to be done.

Tesla Robotaxi heads to a new major Texas city for the first time

Tesla did make its Robotaxi app public in recent months, allowing more members of the public to experience the suite for themselves, as long as they could get to Austin or the Bay Area.

In the coming months, it seems more apparent that Tesla will take a broader focus on expanding Robotaxi, especially with the fact that these validation vehicles are being spotted throughout different parts of the United States.

Tesla mulls revamping $25k car, strange report claims

Tesla is reportedly mulling the potential revamp of its $25,000 vehicle project, a strange report claims.

It seems unlikely, especially since Tesla launched two new, more affordable models last week with the Model 3 and Model Y Standard trims.

However, a report from European media outlet 36kr claims Tesla has started to advance two vehicle projects, internally codenamed E41 and D50, in China.

People familiar with the matter reportedly told the outlet that “some design and verification reports of the new projects are inherited from the current Model Y and Model 3.”

Tesla axed one of the Model Y’s best features in ‘Standard’ trims: here’s why

These new simplified models would be priced between $5,000 and $5,500 cheaper than what the new ‘Standard’ trims cost. The report also claims that these vehicles would be launched only if the new ‘Standard’ models “fall short of sales expectations.”

This report suggests that potentially more affordable models are being offered, but this seems unlikely, considering Tesla launched the two Standard models just last week, and the only truly affordable model it is working on will be the Cybercab.

However, there is potential for a car to launch that undercuts the newest configurations of the Model 3 and Model Y. As of now, it just seems as if it is something that is far-fetched.

When Tesla’s patent for the unboxed process was published just last month, it seemed more than obvious that the vehicle it would be used for was the Cybercab.

The language used in the patent itself was geared toward more streamlined and quality production and manufacturing, which Tesla must implement to meet the likely demand for the vehicle.

It will be easier to scale vehicles with the unboxed process, and the Cybercab has been routinely mentioned with the sub-$30,000 price tag, even by CEO Elon Musk.

He said during the Q3 2024 Earnings Call:

“I think having a regular 25K model is pointless. It would be silly. Like it would be completely at odds with what we believe…It’s fully considered cost per mile is what matters. And if you try to make a car that is essentially a hybrid, manual, or automatic car, it’s not going to be as good as a dedicated autonomous car. So, yes, Cybercab is just not going to have steering wheels and pedals.”

SpaceX aces Starship’s 11th launch with success in every mission objective

SpaceX aces its eleventh Starship test launch on Monday evening, marking the company’s second consecutive takeoff that crossed off each of the planned mission objectives.

It was also the final launch of the V2 Starship rocket. The twelfth test flight will feature the larger V3 Starship rocket, followed by V4, which will eventually make the first trip to Mars.

The launch was overwhelmingly successful. In its 12th test flight, SpaceX was able to achieve every major mission objective, including the second successful deployment of Starlink satellite simulators and the relight of a Raptor engine while in space. The latter achievement demonstrated “a critical capability for future deorbit burns,” the company said.

The ship officially launched at 6:23 p.m. local time in Starbase, Texas, with all 33 engines igniting and sending the Ship to space.

Stage separation occurred just over eight minutes later, and Super Heavy started its descent back to the Gulf of America, where it successfully splashed down. The first part of the launch was complete.

Starlink simulators were deployed about twenty-one minutes after launch, as the Pez dispenser sent the faux-satellites out to space without any issue:

Perhaps the most anticipated part of the launch was with Starship’s banking maneuver and subsequent splashdown in the Indian Ocean.

Prior to Starship 11’s launch and successful re-entry and splashdown, SpaceX had lost a few vehicles during this portion of the previous flights.

However, the company had made tremendous improvements and has now aced two consecutive launches. On Monday, its approach and splashdown were both overwhelmingly successful:

The re-entry phase of this particular Starship launch aimed to gather data on the performance of the heatshield, SpaceX said. The heatshield was intentionally stressed to its limits to determine how much it could withstand without failing.

SpaceX will now turn its focus to the next vehicles, including V3, which is larger, more capable, and will help the company gather even more information about its launches into space:

CEO Elon Musk has said the third-generation Starship rocket will be built and tested by the end of the year.
