SpaceX readies Falcon 9 Block 5s for bi-coastal launches and landings

Published

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.

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.

Cheaper launches as a result of reusable rockets may not necessarily increase demand for satellite launches.

Elon Musk reveals SpaceX’s target for Starship’s 10th launch

Elon Musk has revealed SpaceX’s target timeline for the next Starship launch, which will be the tenth in program history.

Elon Musk has revealed SpaceX’s target timeline for the next Starship launch, which will be the tenth in program history.

Musk says SpaceX is aiming for a timeline of roughly three weeks from now, which would come about ten weeks after the previous launch.

Coincidentally, it would bring the two launches 69 days apart, and if you know anything about Elon Musk, that would be an ideal timeline between two launches.

SpaceX is coming off a test flight in which it lost both the Super Heavy Booster and the Upper Stage in the previous launch. The Super Heavy Booster was lost six minutes and sixteen seconds into the flight, while SpaceX lost communication with the Ship at 46 minutes and 48 seconds.

Musk is aiming for the tenth test flight to take place in early August, he revealed on X:

This will be SpaceX’s fourth test flight of the Starship program in 2025, with each of the previous three flights bringing varying results.

IFT-7 in January brought SpaceX its second successful catch of the Super Heavy Booster in the chopstick arms of the launch tower. The ship was lost after exploding during its ascent over the Turks and Caicos Islands.

IFT-8 was on March 6, and SpaceX caught the booster once again, but the Upper Stage was once again lost.

The most recent flight, IFT-9, took place on May 27 and featured the first reused Super Heavy Booster. However, both the Booster and Upper Stage were lost.

The Federal Aviation Administration (FAA) hit SpaceX with a mishap investigation for Flight 9 on May 30.

Tesla CEO Elon Musk has confirmed that the company will roll out a new feature for in-car Grok as it is rolling out to vehicles for the first time.

Grok was just recently added as a feature to Tesla vehicles within the past week, but owners are already requesting some small changes to make it more convenient to use.

Tesla debuts hands-free Grok AI with update 2025.26: What you need to know

The first is already on the way, Musk confirmed, as WholeMarsBlog requested a simple, but useful feature for Grok as it is used within Tesla vehicles.

Whole Mars requested that “Hey Grok” be used as a wake word, automatically activating the AI assistant without having to touch any buttons. Musk confirmed it is already in development and on the way to vehicles:

This feature is incredibly similar to that of “Hey Siri” with iPhones and other iOS devices. The phone will recognize your voice and hear that prompt, automatically activating Siri. Apple’s assistant will then perform whatever task it is asked to perform. It’s a simple but effective performance feature.

Grok is already getting its first reviews from owners as it rolls out to owners for the first time. It is a long time coming, too. Tesla has been hinting that Grok would be enabled in the vehicles for a while now, and it just started its initial rollout last week.

Grok is available in vehicles with the AMD chip and requires Premium Connectivity or a WiFi connection to use.

Tesla reveals key detail of Supercharger Diner, but it’s bigger than you think

Tesla has finally released one key detail about the Supercharger Diner, and it is bigger than what it appears at face-value.

Tesla has revealed a key detail of its Supercharger Diner as its launch date appears to be nearing, based on what we are seeing at the site currently.

The Supercharger Diner is located on Santa Monica Boulevard in Los Angeles and was first proposed as an idea by CEO Elon Musk back in 2018. Musk envisioned a drive-in movie-style 1950s-inspired diner that would feature elements such as servers on roller skates, large movie screens, and a menu inspired by classic treats from several decades ago.

A project that first broke ground in 2023, the Supercharger Diner has been in development for over two years, as Tesla performed demolition work at the site back in February of that year.

It has slowly moved forward, and drone footage shot this week seems to show things are nearly up and running. Musk even mentioned that he had eaten at the Diner Supercharger this week.

There are still details that Tesla has yet to announce and confirm. The most important thing is regarding the menu that will be served at the diner.

Tesla has not hinted at what it will be making for patrons at the restaurant, but Musk commended the food and said the diner would be one of the coolest spots in LA.

However, we now have details on another important thing about the restaurant: the hours.

Images taken by Aaron Cash of ABetterTheater.com show the diner will be open 24/7, as it appears on the front doors of the diner:

At first thought, it seems this will operate like any other diner, as many are open for 24 hours a day. Diners typically serve large menus with numerous options, catering to the tastes and moods of anyone who walks in.

People of all walks of life eat at diners, as the food is typically affordable, tasty, and available at any hour to serve those who are night owls or those who work non-typical schedules.

However, Tesla is a bit different, and it seems that this new venture into food service could eventually transition from human servers and cooks to robots, most notably the company’s in-house project of Optimus.

It is something straight out of a Star Wars movie. I can think of Obi-Wan Kenobi visiting Dex in his diner in Attack of the Clones to figure out where a poison dart was sourced from:

Eventually, Optimus will likely be working as an employee in the Tesla Diner, and 24/7 operation will be performed by the humanoid robot that aims to eliminate trivial tasks from humans.
