SpaceX tests Falcon 9 Block 5’s landing leg retraction and preps for first reuse

Published

on

In the two months since SpaceX first debuted its Falcon 9 Block 5 rocket upgrade with a successful May 2018 launch and landing, the company has forged ahead with final Block 4 or older launch and two additional launches and recoveries of brand new Block 5 boosters, growing the fleet of flight-proven and thus flight-worthy rocket boosters to three.

Given the dramatic changes implemented in Block 5 and the pathfinder nature of these new boosters, SpaceX has spent much of the following time conducting tests and extensive analyses to verify new designs and new technology, ranging from teardowns to tests of specific components like landing legs on a recently-recovered East Coast booster.

Most prominently on that to-do list was a deep-dive teardown of inaugural Block 5 booster B1046, which was apparently completed within the last week or so – as evidenced by the sooty booster’s appearance at SpaceX’s Cape Canaveral Launch Complex 40 (LC-40) around July 24th. The purpose of that teardown was to give most of Falcon 9’s many thousands of individual and critical components a thorough examination, particularly those parts most impacted and worn by launch, reentry, and landing. That most likely includes B1046’s black octaweb and interstage thermal protection, its nine upgraded Merlin 1D engines, the “dance floor” heatshield at the rocket’s base, and landing legs, among myriad other smaller aspects.

More recently (July 27 and 28), SpaceX technicians attempted and completed the first retraction of a Block 5 booster landing leg (B1047 in Port Canaveral, Florida), compared with the current practice of removing both the landing legs and booms before rotating the recovered rocket horizontal and transporting it to a nearby refurbishment facility. Briefly discussed by CEO Elon Musk, Block 5 includes a number of landing leg optimizations, intended to improve robustness, increase reliability, and significantly ease reuse.

“So essentially deploying the landing gear and stowing the landing gear is now a very easy thing to do [on Block 5 boosters], whereas previously it required several hours to re-stow the landing gear. Which can now be done with an actuator, pretty easily.”

Given the fact that it took a full day to prepare for the retraction of the first leg and that the task appears to be accomplished with a fairly complex and manual lifting mechanism requiring several workers to function, it’s possible that the retraction and leg hardware described by Musk is still undergoing some form of testing or production optimization before being added to flight hardware. Nevertheless, photographer and journalist Ken Kremer observed the retraction sequence from start to finish (movement-wise) and pegged it at around 40 minutes total to go from fully deployed to fully stowed.

In all fairness, truly rapid and near-automatic leg retraction would only be of value to SpaceX once the company needs to refly Falcon 9 with less than a week or two between launches, at which point spending a day or two carefully removing or stowing landing legs outweighs the cost of adding highly specific hardware useless during flight (and thus stealing mass that could otherwise be fuel for a gentler booster recovery or a higher payload orbit).

Keeping as much of that leg retraction hardware on the ground as possible thus makes a lot of sense in today’s launch industry, where SpaceX simply has no material need for near-automatic, internally-actuated leg retraction on Falcon 9 (only necessary for extremely rapid turnaround). Still, if the company hopes to achieve Musk’s 24-hour booster turnaround challenge by the end of 2019, SpaceX technicians and engineers will need to have a solution in place to retract Falcon 9’s landing legs as quickly as practically possible – every minute will count for such a rapid reuse.

Tesla lands massive deal to expand charging for heavy-duty electric trucks

Tesla has landed a massive deal to expand its charging infrastructure for heavy-duty electric trucks — and not just theirs, but all manufacturers.

Tesla entered an agreement with Pilot Travel Centers, the largest operator of travel centers in the United States. Tesla’s Semi Chargers, which are used to charge Class 8 electric trucks, will be responsible for providing energy to various vehicles from a variety of manufacturers.

The first sites are expected to open later this Summer, and will be built at select locations along I-5 and I-10, major routes for commercial vehicles and significant logistics companies. The chargers will be available in California, Georgia, Nevada, New Mexico, and Texas.

Each station will have between four and eight chargers, delivering up to 1.2 megawatts of power at each stall.

The project is the latest in Tesla’s plans to expand Semi Charging availability. The effort is being put forth to create more opportunities for the development of sustainable logistics.

Senior Vice President of Alternative Fuels at Pilot, Shannon Sturgil, said:

“Helping to shape the future of energy is a strategic pillar in meeting the needs of our guests and the North American transportation industry. Heavy-duty charging is yet another extension of our exploration into alternative fuel offerings, and we’re happy to partner with a leader in the space that provides turnkey solutions and deploys them quickly.”

Tesla currently has 46 public Semi Charger sites in progress or planned across the United States, mostly positioned along major trucking routes and industrial areas. Perhaps the biggest bottleneck with owning an EV early on was charging availability, and that is no different with electric Class 8 trucks. They simply need an area to charge.

Tesla is spearheading the effort to expand Semicharging availability, and the latest partnership with Pilot shows the company has allies in the program.

The company plans to build 50,000 units of the Tesla Semi in the coming years, and with early adopters like PepsiCo, DHL, and others already contributing millions of miles of data, fleets are going to need reliable public charging.

Tesla is partnering with other companies for the development of the Semi program, most notably, a conglomeration with Uber was announced last year.

The ride-sharing platform plans to launch the Dedicated EV Fleet Accelerator Program, which it calls a “first-of-its-kind buyer’s program designed to make electric freight more affordable and accessible by addressing key adoption barriers.”

The Semi is one of several projects that will take Tesla into a completely different realm. Along with Optimus and its growing Energy division, the Semi will expand Tesla to new heights, and its prioritization of charging infrastructure.

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%.
