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.
The first Block 5 Falcon 9 lifts off on May 4, 2018. Several more are soon to come. (Tom Cross)

Elon Musk’s Boring Company opens Vegas Loop’s newest station
The Fontainebleau is the latest resort on the Las Vegas Strip to embrace the tunneling startup’s underground transportation system.
Elon Musk’s tunneling startup, The Boring Company, has welcomed its newest Vegas Loop station at the Fontainebleau Las Vegas.
The Fontainebleau is the latest resort on the Las Vegas Strip to embrace the tunneling startup’s underground transportation system.
Fontainebleau Loop station
The new Vegas Loop station is located on level V-1 of the Fontainebleau’s south valet area, as noted in a report from the Las Vegas Review-Journal. According to the resort, guests will be able to travel free of charge to the stations serving the Las Vegas Convention Center, as well as to Loop stations in Encore and Westgate.
The Fontainebleau station connects to the Riviera Station, which is located in the northwest parking lot of the convention center’s West Hall. From there, passengers will be able to access the greater Vegas Loop.
Vegas Loop expansion
In December, The Boring Company began offering Vegas Loop rides to and from Harry Reid International Airport. Those trips include a limited above-ground segment, following approval from the Nevada Transportation Authority to allow surface street travel tied to Loop operations.
Under the approval, airport rides are limited to no more than four miles of surface street travel, and each trip must include a tunnel segment. The Vegas Loop currently includes more than 10 miles of tunnels. From this number, about four miles of tunnels are operational.
The Boring Company President Steve Davis previously told the Review-Journal that the University Center Loop segment, which is currently under construction, is expected to open in the first quarter of 2026. That extension would allow Loop vehicles to travel beneath Paradise Road between the convention center and the airport, with a planned station located just north of Tropicana Avenue.

Tesla leases new 108k-sq ft R&D facility near Fremont Factory
The lease adds to Tesla’s presence near its primary California manufacturing hub as the company continues investing in autonomy and artificial intelligence.
Tesla has expanded its footprint near its Fremont Factory by leasing a 108,000-square-foot R&D facility in the East Bay.
The lease adds to Tesla’s presence near its primary California manufacturing hub as the company continues investing in autonomy and artificial intelligence.
A new Fremont lease
Tesla will occupy the entire building at 45401 Research Ave. in Fremont, as per real estate services firm Colliers. The transaction stands as the second-largest R&D lease of the fourth quarter, trailing only a roughly 115,000-square-foot transaction by Figure AI in San Jose.
As noted in a Silicon Valley Business Journal report, Tesla’s new Fremont lease was completed with landlord Lincoln Property Co., which owns the facility. Colliers stated that Tesla’s Fremont expansion reflects continued demand from established technology companies that are seeking space for engineering, testing, and specialized manufacturing.
Tesla has not disclosed which of its business units will be occupying the building, though Colliers has described the property as suitable for office and R&D functions. Tesla has not issued a comment about its new Fremont lease as of writing.
AI investments
Silicon Valley remains a key region for automakers as vehicles increasingly rely on software, artificial intelligence, and advanced electronics. Erin Keating, senior director of economics and industry insights at Cox Automotive, has stated that Tesla is among the most aggressive auto companies when it comes to software-driven vehicle development.
Other automakers have also expanded their presence in the area. Rivian operates an autonomy and core technology hub in Palo Alto, while GM maintains an AI center of excellence in Mountain View. Toyota is also relocating its software and autonomy unit to a newly upgraded property in Santa Clara.
Despite these expansions, Colliers has noted that Silicon Valley posted nearly 444,000 square feet of net occupancy losses in Q4 2025, pushing overall vacancy to 11.2%.
In Pennsylvania, we got between 10 and 12 inches of snow over the weekend as a nasty Winter storm ripped through a large portion of the country, bringing snow to some areas and nasty ice storms to others.
I have had a Model Y Performance for the week courtesy of Tesla, which got the car to me last Monday. Today was my last full day with it before I take it back to my local showroom, and with all the accumulation on it, I decided to run a cool little experiment: How long would it take for Tesla’s Defrost feature to melt 8 inches of snow?
Tesla’s Defrost feature is one of the best and most underrated that the car has in its arsenal. While every car out there has a defrost setting, Tesla’s can be activated through the Smartphone App and is one of the better-performing systems in my opinion.
It has come in handy a lot through the Fall and Winter, helping clear up my windshield more efficiently while also clearing up more of the front glass than other cars I’ve owned.
The test was simple: don’t touch any of the ice or snow with my ice scraper, and let the car do all the work, no matter how long it took. Of course, it would be quicker to just clear the ice off manually, but I really wanted to see how long it would take.

Observations
I started this test at around 10:30 a.m. It was still pretty cloudy and cold out, and I knew the latter portion of the test would get some help from the Sun as it was expected to come out around noon, maybe a little bit after.
I cranked it up and set my iPhone up on a tripod, and activated the Time Lapse feature in the Camera settings.
The rest of the test was sitting and waiting.
It didn’t take long to see some difference. In fact, by the 20-minute mark, there was some notable melting of snow and ice along the sides of the windshield near the A Pillar.
However, this test was not one that was “efficient” in any manner; it took about three hours and 40 minutes to get the snow to a point where I would feel comfortable driving out in public. In no way would I do this normally; I simply wanted to see how it would do with a massive accumulation of snow.
It did well, but in the future, I’ll stick to clearing it off manually and using the Defrost setting for clearing up some ice before the gym in the morning.
Check out the video of the test below:
