SpaceX nails first reuse of its next-gen Falcon 9 Block 5 rocket

Published

on

SpaceX has successfully reused the first Falcon 9 Block 5 booster less than three months after the rocket’s major reliability and reusability upgrade debuted. This milestone may feel small in the shadow of SpaceX’s accomplishments over the last ~18 months but make no mistake: the second flight of a Block 5 booster is by far the company’s most significant achievement in recent years.

First and foremost, this is by no means meant to demean the awe-inspiring reality of what SpaceX has managed over the last several years, which includes the first successful Falcon 9 landing, the first commercial orbital-class rocket reuse (also Falcon 9), and the first commercial reuse of an orbital spacecraft (Cargo Dragon), and many others. Rather, it really is the case that the first Block 5 reuse is one of the most important things ever done by SpaceX.

 

Why is this launch so significant?

As noted by webcast host and engineer Lauren Lyons, the second successful drone ship recovery of Falcon 9 Booster 1046 (B1046) paves the way for the SpaceX’s first-ever third launch of the same rocket. The number “3” may not immediately feel significant, but in the case of Falcon 9, the third reuse of a booster has always remained out of reach for older versions of the rocket, walled off by the exponentially greater cost and effort required to refurbish non-Block 5 rockets after their first reuse. Block 5 is different, and that’s by design.

Put very simply Falcon 9 Block 5 is an iteration of the venerable launch vehicle that best represents SpaceX moving from reusable rockets as experimental prototypes to a successfully developed and implemented technology – with Block 5, SpaceX is effectively proclaiming that Falcon 9’s reusability design has been completed and optimized thanks to dozens of rocket landings (28) and reuses (15).

 

With the third reuse now explicitly on the table for B1046 “later this year”, Falcon 9 has broken a two-launch ceiling that long loomed over its older predecessors. The third reuse will pave the way for the 4th, 5th, 10th, 50th … reflight of individual Falcon 9 boosters, an absolutely integral requirement for SpaceX to achieve its ultimate goals of sustainably colonizing the solar system – starting with Mars – and thus ‘backing up’ humanity.

B1046’s second suborbital jaunt and landing aboard drone ship Of Course I Still Love You will almost undoubtedly be a turning point in the future history of SpaceX. For those that missed the stream or just want to watch again, catch the milestone launch below.

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 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%.

Tesla winter weather test: How long does it take to melt 8 inches of snow?

Published

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 Model Y Performance set for new market entrance in Q1

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.
