SpaceX to launch one of its last old-gen Falcon 9s in upcoming launch
One of SpaceX’s rapidly shrinking fleet of older Falcon 9 launch vehicles has rolled out to the company’s California launch pad ahead of an expendable launch and fairing recovery attempt scheduled for no earlier than Tuesday (NET) 12:47 pm PST/19:47 UTC May 22.
Although SpaceX may have inaugurated a new era of truly reusable rocketry with the debut of Falcon 9 Block 5 earlier this month, there are still a number of older Falcon 9 boosters (all flight-proven) awaiting their second and final flights. At the moment, a minimum of four cores remain, including the sooty Falcon 9 first stage captured earlier this evening by Teslarati photographer Pauline Acalin.
Foreshadowing its imminent watery demise with a lack of landing legs, this particular booster (B1043) previously launched the mysterious and controversial Zuma mission in January 2018, a classified payload claimed (sans convincing evidence) to have failed and reentered Earth’s atmosphere mere hours after reaching orbit. While it’s possible that the mission was a failure, at the moment unsteadily blamed on the failure of a Northrop Grumman-designed payload adapter and deployment mechanism, it’s far more probable that the apparently wildly-expensive satellite is still in orbit.

Checking the pulse of Earth’s gravity
Regardless, the same SpaceX rocket booster responsible for lifting Zuma and the Falcon 9 upper stage out of the atmosphere is now ready to launch a new payload at SLC-4E, a launch pad stationed in Vandenberg Air Force Base. B1043’s second orbit-destined payload is a compliment of seven satellites: five are of the Iridium NEXT variety and the remaining satellites make up a scientific mission and technology demonstrator known as GRACE-FO (FO for Follow-On).

Following in the footsteps of the original GRACE’s (Gravity Recovery and Climate Experiment) 15 year orbital tenure, GRACE-FO is effectively the same mission with significantly upgraded hardware – the biggest experimental component is actually an advanced laser interferometer designed to measure the distance between the two satellites (roughly equivalent to the distance between LA and San Diego) with the precision of a single micrometer (10-100x smaller than the width of a human hair). At that level of precision, the pair of satellites can detect minute changes in Earth’s gravity, to the extent that they can actually observe droughts, floods, and ice melt through the change in gravity caused by the movement of large (i.e. heavy) quantities of water. If the experimental laser ranging technology works as intended, it will be at least ten times more accurate than the microwave-ranging technology also installed on the follow-on satellites.
SpaceX’s rocket fleet makes way for Block 5
On the SpaceX side of things, Falcon 9 B1043 will be expended after dutifully completing the launch of Iridium-6/GRACE-FO, although the presence of grid fins on the rocket indicates that SpaceX will likely continue a regime of soft-landing recovery tests to optimize and flesh out the limits of Falcon 9’s capabilities. At first glance, the tradeoff of expending entire rocket boosters able to be (relatively inefficiently) refurbished for considerably more than two flights seems extreme and inadvisable. However, SpaceX is presumably ravenous for data on the survivable envelope of Falcon 9 performance – particularly reuse – in advance of the complete transition to the rocket’s Block 5 iteration, a significant upgrade likely to come hand in hand with a more pronounced aversion to expendable missions given each booster’s design lifespan of 10 to 100 missions. At that level of reusability, expending Falcon 9 Block 5s would truly become comparable with the absurdity of trashing an airliner after one or a handful of flights, an (in)famous talking point used by Elon Musk over his years of public SpaceX discussions.

Thus, if SpaceX can gather data that might enable future Falcon 9 Block 5 recoveries by expending much less valuable Block 3 and 4 boosters, the payoff would be irresistible once examined with a long-term outlook. In the sense that Block 5 may be capable of magnitudes more flights with considerably cheaper refurbishment, the literal elemental value of the hardware – in the likely event that Block 5 production is more capital-intensive than Block 3/4 – is more or less irrelevant for an aversion to expending Block 5 boosters.
Rather, what is lost alongside an expendable Block 5 mission is instead the comparatively vast amount of revenue locked within dozens of additional highly-profitable launches each expended booster could have supported. From that perspective, expending Block 3s and 4s to gather data might be accurately compared to destroying single-pilot Cessnas to improve the utility of a 747 airliner.
After B1043 is expended, only three obvious flightworthy cores will remain outside of the gradually growing Falcon 9 Block 5 fleet (just two boosters, currently). In order of anticipated launch, these three missions are SES-12 (NET May 31), CRS-15 (NET June 28), and the Crew Dragon in-flight abort test (NET Q4 2018). Barring the unexpected refurbishment of an older flight-proven core for a third mission, these final three missions will bring to a close the inherently temporary era of partially-reusable SpaceX rockets – in the words of Elon Musk, Block 5 would thus signify that SpaceX has moved from “the dog that caught the bus” to, perhaps, the dog that caught the bus and then learned how to drive and maintain it. Somewhere in the middle of those final throes of old-guard Falcons will be an ever-increasing cadence of Block 5 launches and re-launches, likely including the first manifest-necessitated reuse of a Block 5 booster sometime this summer.

Meanwhile, despite the sealed fate of the rocket’s booster, tomorrow’s launch will debut fairing-catcher Mr Steven’s new and improved net. With the introduction of an upgraded net and what can only be described as back-to-back days of relentless ocean-going practice over the last two weeks, it’s entirely possible that Iridium-6/GRACE-FO will be able to lay claim to the first successful catch of a payload fairing following an orbital rocket launch. Fingers crossed.

The Tesla Semi is entering a new Pilot Program with Paper Transport, LLC (PTI), a Wisconsin-based transportation provider. The company will test the Semi’s Long Range configuration through “dedicated operations within the Chicago market.”
Chicago presents an interesting challenge for the Semi, as it will be a colder-weather climate that will test the Semi’s ability to operate in lower temperatures and in potentially large accumulations of snow. This is something Tesla has been testing with the Semi in Alaska and even in Northern California during the colder months, but Chicago will present a truly tough midwestern winter.

PTI says it is using the Semi to evaluate its strategy of reducing transportation emissions while maintaining performance, reliability, and cost efficiency. These are major arguments for the Semi being introduced into new fleets.
CEO of PTI Tyler Ellison said:
“PTI has been a leader in sustainable transportation solutions for over 15 years. We take a consultative approach to helping customers identify and implement the right transportation solution for their network. Our partnership with Tesla expands our portfolio alongside renewable natural gas and intermodal, giving customers more ways to reduce Scope 3 emissions without compromising service or economics.”
PTI is far from the first company to adopt the Semi within a fleet, as Tesla entered strategic agreements with PepsiCo. and its subsidiary Frito-Lay for a Pilot Program that extended throughout the California region.
Tesla has let companies like those utilize the Semi to determine whether it would be suitable for their operations. Additionally, Tesla gets valuable information regarding the Semi’s performance, knowing what to improve and what is ideal for companies that will utilize the all-electric truck for regional and nationwide logistics.
PTI plans to utilize the Long Range configuration, which is priced at $290,000 and features a range of approximately 500 miles, a three-motor powertrain, up to 800 kW of drive power, and consumption of just 1.7 kWh per mile.

VP of Maintenance at PTI, Bryan Ellen, added:
“We are excited to partner with Tesla, leveraging their ever-evolving technology. We are bullish in our estimation of the parallels available between our dedicated model and the efficiency of their fully electric Class 8 tractor. We anticipate a growing synergy between our businesses as we work to facilitate this sustainable solution for our customers.”
PTI has logged more than 87 million miles using sources like compressed and renewable gas, but now is looking to take it a step further with fully electric operations.
Tesla revealed on Monday that it is building a new autonomous vehicle at Gigafactory Texas, its plant just outside of the City of Austin. This particular vehicle will be geared toward those who are in need of a wheelchair-accessible car that would require no human driver for operation.
According to a new report from Wired, Tesla’s Senior Policy Advisor, India Herdman, told members of the Washington D.C. City Council on Monday:
“We are in development for a purpose-built, wheelchair-accessible autonomous vehicle. We know that paratransit can be very difficult, and people who are confined to wheelchairs permanently should still be able to move around freely, so that is an active product being built by Tesla in Texas.”
This builds upon what CEO Elon Musk said last year on X, which confirmed the company was working on accessible rides within its Robotaxi platform, which currently is confined to the Model Y.
Absolutely

Tesla is also developing the Cybercab, which started employee rides last week. However, this vehicle is not necessarily geared toward wheelchair accessibility.
That leaves a major gap in the autonomous ride-sharing program that Tesla is attempting to build; the company has been pretty clear that it does not want to complicate its manufacturing lines by bringing in a wide array of body styles.
However, it seems necessary to have something larger that could help transport people to appointments when they cannot drive. For wheelchair accessibility, the Robovan, which was unveiled at the “We, Robot” event in October 2024, seems to be the most ideal solution:
Herdman did not indicate whether she was referring to the Robovan or if Tesla is building yet another body style that is geared toward full autonomy but also caters to the handicapped.
Tesla might need to develop something specifically for the handicapped in order to align with the Americans with Disabilities Act, which prevents discrimination against people with disabilities in transportation services. Uber was hit with a lawsuit late last year for “refusing to reasonably modify its policies, practices, or procedures where necessary to avoid discriminating against riders with disabilities.”
Tesla would obviously like to avoid this.
It will be interesting to see what Tesla will do with this project, and whether it will introduce something new to the market or just continue with the Robovan.
Tesla weirdly confirmed that its steering wheel-less and pedal-less Cybercab vehicle is now in the process of giving employees rides, a huge milestone for the vehicle program.
But the entire thing was super strange. On Friday, Tesla released a video stating that there was “Cool news from Giga Texas” and that employees were now taking rides in Cybercabs that have no manual controls. The units seen on public roads are engineering vehicles that have manual controls inside, a necessity as Tesla moved through the testing phase.
However, Tesla removed the video and reposted it shortly after with a more vague title. It seems like the employee rides are still going, but the video was adjusted slightly. The initial upload showed employees doing things like watching movies and adjusting the climate, but these snippets were removed in the second upload.

Nevertheless, the announcement from Tesla is that the Cybercab is operating with employees inside who can control the vehicle’s audio, video, climate, and destination settings through their smartphone app.
Tesla has already been testing Cybercab engineering units, but last month, it was able to self-certify for SAE Level 4, which would enable unsupervised self-driving in Texas. The company is moving toward that, and the plans have always been to launch Cybercab rides this year.
The Cybercab is potentially looked at as the next generation of Tesla’s mobility leg. For the past 15 years, the company has been known as somewhat of an automaker, among many other things. However, these passenger vehicles that Tesla has manufactured are now moving into a new realm, as they will eventually drive themselves with no supervision thanks to the Full Self-Driving suite.
The Cybercab is just the next step of that: a true vehicle developed for the sole purpose of ride-hailing. It has no human controls, it has only two seats, and it will get passengers from Point A to Point B with no awkward driver, no need for manual inputs, and with no stress.
Tesla is moving forward with other developments related to the Cybercab project as well. However, the big announcement will come when Tesla finally announces that it is launching Cybercab rides to the general public, something that it plans to launch either late this year or early 2027.
