SpaceX readies Falcon 9 Block 5s for bi-coastal launches and landings
After several months of preparation behind the scenes, SpaceX’s second and third serial Falcon 9 Block 5 rockets are ready for the first launches of the upgraded vehicle from Vandenberg Air Force Base, CA (VAFB) and Cape Canaveral Air Force Station, FL (CCAFS).
On the calendar for 1:50 am EDT/5:50 UTC July 22 and 4:39 am PDT/11:39 UTC July 25, SpaceX launches of Telstar 19V and Iridium NEXT-7 are set to mark the beginning of a new era for the company, where all future missions will fly with Block 5 hardware upgraded for reusability and reliability and attempt recovery almost without fail.

Bursting out of the expendable rocket cocoon
While it may be the case that an odd launch or two require a booster be expended to prevent schedule delays or carry an exceptionally heavy satellite to an exceptionally high orbit, it’s safe to say that such a mission with Block 5 boosters will be an anomaly. Somewhat iffy comments posted on Reddit recently claimed that Falcon Block 5 boosters would be able to easily (and rapidly) hop between roles as side and center boosters for both Falcon 9 and Falcon Heavy. While wild, those claims, in retrospect, make a lot of sense, even if the reality of Block 5 booster interchangeability was a tad exaggerated.
If SpaceX truly wants to end the practice of expending rocket boosters, – and eventually fairings and upper stages, with any luck – the company will truly need to embrace a strategy that’s long been floated by executives like CEO Elon Musk and COO/President Gwynne Shotwell. That strategy dictates that SpaceX routinely use both Falcon 9 and Falcon Heavy as an almost interchangeable and rocket team capable of launching nearly every orbital payload conceivable today, all while remaining in fully or mostly reusable modes of operation.

At the moment, educated estimates of Falcon Heavy’s true performance margins with dual booster landings at SpaceX’s Florida landing zones and center core recovery aboard Of Course I Still Love You (OCISLY) suggest that the Block 5 version of Falcon Heavy should be capable of launching every commercial satellite planned or penciled in for launch over the next five years, at a minimum. Finally, while the Falcon family’s fuel choice of high-grade kerosene (RP-1) and liquid oxygen make the rocket far more compact and energy-dense than alternatives, one downside of that choice is a loss of efficiency, although brute-force strength makes FH a competitive beast for all missions beyond Earth orbit (Mars, Venus, Saturn, asteroids, comets, etc).
However, a fully-expendable Block 5 Falcon Heavy seems to be at least 3X as unlikely as an expendable Block 5 Falcon 9. Nevertheless, CEO Elon Musk made it clear that a nominal Falcon Heavy launch where both side boosters were recovered at sea and the center booster expended could accomplish a full ~85-90% of an entirely expendable mission, and for roughly $95m. As such, a combination of reusable Falcon 9s, reusable Falcon Heavys, and ~30%-expendable Falcon Heavys could successfully complete every plausible commercial and non-commercial launch in the world and do so at the lowest cost for the better part of the next five years, at which point the company’s next-gen Big F____ Rocket (BFR) ought to be operational.
Side boosters landing on droneships & center expended is only ~10% performance penalty vs fully expended. Cost is only slightly higher than an expended F9, so around $95M.

Telstar 19V and Iridium-7
With any luck, SpaceX’s next two launches will be the first huge step in the direction of that one-stop-shop for competitive transportation to orbit. Teslarati photographer Tom Cross will be setting up remote cameras for the Telstar 19V’s Florida liftoff later this evening, while our West Coast fellow and famed Mr Steven-stalker Pauline Acalin will be setting up her own set of remote cameras for VAFB’s Falcon 9 Block 5 debut on Tuesday.

On the East Coast, drone ship OCISLY has already departed Port Canaveral with a duo of support vessels and a dedicated tugboat, while the West Coast’s Just Read The Instructions (JRTI) will likely take leave of the Port of Los Angeles within 24 hours. Those dual, successful (?) rocket landings will hopefully mark the first of many dozens of missions for F9 boosters B1047 and B1048.

SpaceX set to launch astronauts and a classified Falcon Heavy mission on the same day
SpaceX plans three launches Thursday, including Crew-13 astronauts and Falcon Heavy’s first classified NRO mission.
SpaceX is lining up one of the busiest single days in its history, and the company offered a preview on Wednesday morning with a simple post on X: “Sunrise at pad 40.” The video and photos show Falcon 9 standing at Space Launch Complex 40 at Cape Canaveral, roughly a day before it is scheduled to carry four astronauts to the International Space Station.
That launch is only the first of three SpaceX missions planned for Thursday, October 1, across both coasts.

Crew-13 is targeting liftoff at 11:10 a.m. ET, with a backup opportunity Friday at 10:47 a.m. ET. NASA astronaut Jessica Watkins will command the mission, with NASA’s Luke Delaney as pilot and Canadian Space Agency astronaut Joshua Kutryk and Roscosmos cosmonaut Sergey Teteryatnikov serving as mission specialists. According to NASA, Dragon is set to dock with the forward port of the station’s Harmony module around 8 p.m. ET, less than nine hours after launch. Watkins is the only member of the crew who has flown before, and Kutryk will become the first Canadian to reach orbit through NASA’s Commercial Crew Program.
The Falcon 9 booster is flying for the third time after supporting Crew-12 and a Starlink mission, and it will attempt a landing at Landing Zone 40 beside the pad. That site made its debut in February when the Crew-12 booster touched down there, as Teslarati reported at the time. Crew-13 will relieve the Crew-12 astronauts, who have been aboard the station since the middle of February.
On the West Coast, another Falcon 9 is scheduled to lift off from Vandenberg Space Force Base in a window running from 2:18 to 3:16 p.m. ET, a flight NASASpaceflight lists as a Transporter rideshare mission.
The day is set to close at 11:53 p.m. ET, when Falcon Heavy launches from Launch Complex 39A with NROL-97, the first National Reconnaissance Office payload ever to fly on the rocket. SpaceX rolled the vehicle out to the pad Tuesday night. Its two side boosters, which previously flew GOES-U, ViaSat-3 F3 and NASA’s Roman Space Telescope, will return to Landing Zones 1 and 2, while a new center core will be expended in the Atlantic. The Roman launch took place on August 30, so NROL-97 will come barely a month later as Falcon Heavy’s third flight of 2026 and 14th overall.
NASA taps SpaceX to launch the telescope that could unlock new worlds
If all three Florida boosters land as planned, it would be the first time the Space Coast has seen landings at LZ-40, LZ-1 and LZ-2 on the same day, according to the Orlando Sentinel, which has warned residents in Brevard, Orange and Volusia counties that more than one sonic boom is possible.
The schedule arrives just three days after Starship reached orbit for the first time on Flight 14 from Starbase, Texas, deploying 26 Starlink V3 satellites. If Thursday’s missions stay on time, SpaceX will have flown Starship, Falcon 9 and Falcon Heavy from four different pads in about four days.
Crew-13 is also the start of a longer run for Dragon. NASA recently added Crew-15, Crew-16 and Crew-17 to SpaceX’s contract in a $946 million modification, keeping Dragon as the agency’s only operational ride to the station while Boeing’s Starliner remains grounded.

Tesla Cybercab and Semi have more in common than you might think
Although the two vehicles are built for completely different use cases, Tesla utilized engineering expertise while developing both the Cybercab and Semi to build a thermal architecture that would fit both vehicles. Of course, with some slight revisions.
The development was noted by Lars Moravy and Dan Priestley last week at Tesla’s Semi Handover event in Sparks, Nevada, where the company showed off its dedicated production facility for the Class 8 truck.
🚨 Tesla designed the integrated thermal systems for Cybercab and Semi at the same time as the vehicles were both in development
Tesla wanted to build one thermal system that worked with both vehicles, apart from small modifications.
Semi and Cybercab share parts 🤯 pic.twitter.com/KmzSsUbrcg

Tesla’s decision to develop one thermal architecture for both the Cybercab and Semi is one of the more revealing engineering choices in the company’s 2026 lineup:
“We designed it at the same time we designed the Cybercab and we said okay we’re going to take our most efficient vehicle and our biggest vehicle and we’re going to take one thermal system and make it work for both.”
Core parts, meaning the compressor, pumps, and heat exchangers, are shared, with only modest changes to cooling-loop sizing and a larger radiator on the truck. The result, they said, is a compressor and thermal stack already proven across millions of miles, delivering “reliability from day one.”
Priestley also highlighted a practical payoff of the indirect design:
“There’s no AC lines, there’s no refrigerant lines…It comes from the factory fully charged, sealed with refrigerant, and it just exchanges coolant. It doesn’t actually run refrigerant up to the front of the vehicle.”
This eliminates potentially leak-prone plumbing that would otherwise require hands-on service, reducing overall uptime and potentially cutting into business margins. The megamanifold runs cabin HVAC and every powertrain heating and cooling loop at once, recapturing waste heat from motors and the battery instead of dumping it the way a diesel engine does.
The approach is just the latest chapter in a continuing story of stretching thermal solutions across wildly different vehicles. Model Y’s Octovalve evolved into the Super Manifold used on Cybertruck, and later Model S/X refreshes. Cybercab then introduced Supermanifold V3, which Tesla says is 80 percent automated to build and 38 percent more efficient than typical automotive thermal systems.
This thermal system is also shared with Cybercab – one thermal system for both our most efficient vehicle & our biggest vehicle
— Tesla Semi (@tesla_semi) September 25, 2026
Tesla has done the same with the 4680 cells, both being utilized in the Cybertruck and Semi, and with heat-pump compressors that Priestley noted were already common across the passenger-car fleet.
Concurrent development of crucial vehicle elements buys scale and reliability that a truck-only thermal system could not match. High-volume passenger car parts are cheaper and more accessible, which can give fleets a sealed, low-maintenance loop of operation from their first day of operation.
For owners and operators, that translates into less energy spent on cabin heat in the colder months, fewer refrigerant-related repairs, and a thermal architecture already stress-tested at passenger-car volumes before the first high-volume Semi left the lines in Nevada.

Elon Musk weather update tips Tesla Roadster speculation into Plaid Mode
Tesla CEO Elon Musk certainly tipped off some details of the Tesla Roadster event with a broadening of information regarding the company’s decision to delay the unveiling for two weeks.
For years, people have speculated about what the Roadster will be capable of. While there have been plenty of things said about what it *could* do, we have not seen or been told by Tesla what it will actually be capable of.
However, over the past few days, Tesla’s weather updates have truly pushed the speculation into Plaid Mode, basically all but confirming the car will have some sort of aerial capability — whether that would be hovering or fully flying remains to be seen — but it definitely seems that it will be able to leave the ground intentionally.
“Because this event can only be held outdoors…”
Tesla posted on Monday that it would delay the Roadster event until October 15, and it indicated that it had to do this because the event “can only be held outdoors.”
With the potential SpaceX collaboration to develop cold-gas thrusters that will help the vehicle go airborne, doing this indoors is probably not a safe, or even plausible, possibility.
Roadster event update
We’ve been tracking the weather closely with local meteorologists, but given the severe conditions predicted & because this event can only be held outdoors, we’ve made the difficult decision to reschedule.
New date is October 15. Additional details to…

FAA Airspace Restriction
The FAA gave Tesla a Temporary Flight Restriction (TFR) for 10,000 feet above ground level, much higher than the typical 2,000-foot restrictions that are usually placed at SpaceX’s McGregor, Texas site.
Tesla Roadster event requires restricted airspace, and the FAA obliges
Some have said that this massive increase is due to Tesla’s need to restrict unauthorized drone use for spying on the event.
Elon Admits High Winds
“Due to high winds, the new Roadster demo is postponed by 2 weeks,” Musk said in a post on X yesterday.

A reply reading, “What’s strong wind got to do with a car demo with four grounded wheels?” was directly below Musk’s post, satirically and sarcastically probing for more details.
All signs are pointing toward an aerial demonstration for the Roadster.
