SpaceX to test last old-gen Falcon 9’s orbital upper stage lifespan tonight
SpaceX Falcon 9 B1045 is just hours away from completing its second and final mission, a launch that will also signify a swan-song for the reusable rocket company’s Block 4 and older boosters. Not one to let an opportunity go to waste, Elon Musk’s space company intends to do a long coast demonstration of the orbital upper stage once the reused Cargo Dragon spacecraft separates.
Jessica Jensen, SpaceX’s Director of Dragon Mission Management, spoke among a panel of CRS-15 stakeholders on the morning of June 28 and spoke evident pride and confidence in the company’s progress up to this point, with respect to both the mission at hand and SpaceX’s achievements more generally. CRS-15, the third flight-proven Dragon and Falcon 9 launch, is a fitting mission for SpaceX to bring to a close their H1 launch manifest (the 12th of 2018), mainly due to the impressive fact that more than two-thirds of the boosters launched this year have been flight-proven.

As Jensen rightfully noted, SpaceX completed its first-ever reuse of a recovered Falcon 9 booster scarcely 15 months ago in March 2017, a period in which SpaceX has since completed 26 missions, recovered 16 Falcon 9 and Heavy boosters, and successfully launched 12 flight-proven rocket boosters. At the current rate of launch, SpaceX is likely to smash its previous annual cadence record – 18 in 2017 – with anywhere from 24 to 28 launches this year, with CRS-15 marking a dozen missions in the first half of the year, if successful. As such, simply the launch frequency in the first six months would bring SpaceX to 24 completed missions this year. A slight uptick, perhaps as a result of the rapid reusability of new Block 5 boosters, might allow SpaceX to squeeze in several additional missions.

Critically, Jensen also noted that B1045’s final launch will be significant for a reason other than the fact that it nearly halved the previous record for Falcon 9 booster refurbishment, an accomplishment she ceded to the skill and growing experience of SpaceX’s rocket refurbishment teams of engineers and technicians. Aside from that growing expertise, she stated that
“[CRS-15] will also be the final Block 4 configuration of a Falcon 9 booster that SpaceX flies, so all the boosters from here on out will be the Block 5 version.”
Barring unforeseen design flaws, Falcon 9 Block 5 has the potential to be a game-changer, perhaps allowing SpaceX to finally realize a long-term goal of dramatically lowering the cost of access to orbit with new reliable, reusable rockets. Reported by NASASpaceflight.com to be flying aboard a Block 4 booster, something also confirmed to Teslarati through a separate source, it’s not 100% clear if Jensen’s blanket statement included the upcoming in-flight Crew Dragon abort test, scheduled sometime after the upgraded Dragon’s first launch in late 2018. Regardless, she is fully correct in the sense that all future commercial SpaceX launches after CRS-15 will quite definitively fly aboard Falcon 9 and Heavy Block 5 rockets.

Flight-proven Cargo Dragons a new norm for SpaceX
Meanwhile, the specifics of CRS-15 mirror SpaceX’s two most recent International Space Station resupply missions, both of which simultaneously flew flight-proven orbital Cargo Dragon spacecraft and flight-proven Falcon 9 boosters, leaving just the second stage and Cargo Dragon trunk to be expended. As a taste of the future SpaceX fully intends to realize, the spectacle of these CRS missions is not only undeniable but demonstrates a newfound confidence in commercial reusable rockets growing within NASA, an agency that SpaceX would quite simply not be here today without.

After CRS-15, SpaceX has another five flight-proven Cargo Dragon missions left on their CRS-1 contract, after which the updated CRS-2 contract will take over, replacing the old Cargo Dragon with an upgraded cargo version of SpaceX Crew Dragon, also known as Dragon 2. CRS-2 launches are currently scheduled to begin sometime in 2020.
Finally, reminiscent of Falcon Heavy’s spectacular debut launch, Falcon 9’s upper stage “will be doing a long coast demonstration [after Cargo Dragon separates from the rocket]”. Jensen was unable to go into more detail here, but it can be safely presumed that the S2 coast test is either related testing for upper stage reusability or is being used as an opportunity to further demonstrate on-orbit coast capabilities to the US Air Force and/or NASA, a feature that is necessary for certain national security and interplanetary missions.

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:
