SpaceX Starship ‘launch tower’ spreads its rocket-catching arms

(Starship Gazer)

Published

Update: Shortly after publishing, SpaceX began a much more ambitious series of tests with the Starship launch tower’s two main arms, which are designed to lift and (one day) catch Starships and Super Heavy boosters.

After lifting the arm carriage about 15m (~50 ft), several times higher than January 3rd’s far more conservative kickoff, SpaceX fired up each arm’s main hydraulic actuator and opened them about as wide as they’re able to move. Unsurprisingly, the arms’ first powered lateral movement happened very slowly, obviously telegraphing caution but probably also hinting at the start of a calibration process needed to determine their full range of motion and associate those positions with certain sensor readings or telemetry to ensure they can be safely controlled. As of midnight CST, that testing has continued well into the night.

Regardless of the purpose, substantial powered movement is a major milestone for the tower’s main arms and all but guarantees that more extensive tests and simulations are soon to come.

SpaceX has moved Starbase’s rocket-catching “chopstick” arms for the first time since they were installed on the orbital Starship pad’s ‘launch tower’ two months ago.

After a shockingly brisk three-month period of assembly, the first arm installed in late August 2021 was a lone structure designed to swing in; grab and stabilize Super Heavy with its claw; fuel and power Starship; and quickly detach and swing away from the rocket during launch. A month and a half later, SpaceX begin installing a much larger pair of more complex arms in mid-October. Unlike the Starship quick-disconnect (QD) arm, the pair of arms that followed were almost nothing like anything built as part of another rocket launch complex.

Unlike other ‘arms’ related to other rocket launch facilities, the pair SpaceX began to install on Starbase’s launch tower were colossal, measuring more than 30m (100+ ft) long and 5-10m (15-30 ft) tall. Built out of heavy-duty steel pipe and affixed to an even sturdier pair of claw-like supports that grab onto the launch tower, the combined assembly likely weighs hundreds of tons. Aside from their sheer scale, Starbase’s main tower arms are also attached to a complex system of cables and an industrial-strength ‘drawworks’ commonly used on giant oil rigs and derricks.

They also feature huge actuators that allow the two arms to open and close, revealing a bit of their purpose. While the main reason they likely exist is to provide SpaceX with an all-weather alternative to cranes for lifting, manipulating, and precisely stacking Starships and Super Heavy boosters at the launch pad, the headline – ever since Musk revealed the idea – has always been plans to use those same arms to literally catch rockets out of mid-air.

To do so, they’ll need to be able to actuate and move extremely quickly and precisely up and down the Starship launch tower, matching the velocity and autonomously determining the position of landing Super Heavy boosters (and possibly Starships) to avoid major damage or the loss of entire vehicles. While arguably an unnecessary gamble and an attempt to micro-optimize the concept of operations of a rocket that’s yet to attempt a single orbital-class launch, SpaceX’s CEO is clearly committed to the idea and – whether or not the first iteration works – has fully delivered on the first complete lift-and-catch system.

On January 3rd, 2022, after removing a large amount of scaffolding in the days prior, SpaceX briefly and slightly moved the installed arms for the first time, using the drawworks to lift the entire arm-and-carriage assembly a few meters (~6 ft) up and down the tower. Once a few minor additional steps are taken, the chopsticks could be ready for much more extensive testing, beginning with basic lift, descent, and arm actuation tests to calibrate and then proof the first-of-its-kind mechanism. Later, SpaceX will likely simulate catching rockets in a wide range of scenarios. Somewhere before, during, or after that testing, SpaceX may perform another fit test with Starship S20 and Super Heavy B4 – but this time using the arms to lift and install the stages.

NASA watchdog says Starship development delays could affect Artemis timeline

The report noted that several technical milestones still need to be completed before Starship can serve as a crewed lunar lander.

A NASA watchdog report stated that continued development work on SpaceX’s Starship could affect the timeline for the agency’s planned Artemis moon missions. The report noted that several technical milestones still need to be completed before the spacecraft can serve as a crewed lunar lander.

The findings were detailed in a report from NASA’s Office of Inspector General, as noted in a report from Reuters.

NASA selected SpaceX’s Starship in 2021 to serve as the Human Landing System (HLS) for its Artemis lunar program. The vehicle is intended to transport astronauts from lunar orbit to the surface of the Moon and back as part of future Artemis missions.

According to the watchdog report, Starship’s development has experienced roughly two years of schedule delays compared to earlier expectations. Still, NASA is targeting 2028 for the first crewed lunar landing using the Starship lander.

One of the most significant technical milestones for Starship’s lunar missions is in-space refueling.

To support a crewed lunar landing, multiple Starship launches will be required to deliver propellant to orbit. Tanker versions of Starship will transfer fuel to a storage depot spacecraft, which will then refuel the lunar lander.

The report noted that this approach could require more than 10 Starship launches to fully refuel the spacecraft needed for a single lunar landing mission.

NASA officials indicated that demonstrating cryogenic propellant transfer in orbit remains one of the most important technical steps before Starship can be certified for lunar missions.

SpaceX has conducted 11 Starship test flights since 2023 as the company continues developing the fully reusable launch system. A 12th test flight, this time featuring Starship V3, is expected to be held in early April.

SpaceX weighs Nasdaq listing as company explores early index entry: report

The company is reportedly seeking early inclusion in the Nasdaq-100 index.

Elon Musk’s SpaceX is reportedly leaning toward listing its shares on the Nasdaq for a potential initial public offering (IPO) that could become the largest in history. 

As per a recent report, the company is reportedly seeking early inclusion in the Nasdaq-100 index. The update was reported by Reuters, citing people familiar with the matter.

According to the publication, SpaceX is considering Nasdaq as the venue for its eventual IPO, though the New York Stock Exchange is also competing for the listing. Neither exchange has reportedly been informed of a final decision.

Reuters has previously reported that SpaceX could pursue an IPO as early as June, though the company’s plans could still change.

One of the publication’s sources also suggested that SpaceX is targeting a valuation of about $1.75 trillion for its IPO. At that level, the company would rank among the largest publicly traded firms in the United States by market capitalization.

Nasdaq has proposed a rule change that could accelerate the inclusion of newly listed megacap companies into the Nasdaq-100 index.

Under the proposed “Fast Entry” rule, a newly listed company could qualify for the index in less than a month if its market capitalization ranks among the top 40 companies already included in the Nasdaq-100.

If SpaceX is successful in achieving its target valuation of $1.75 trillion, it would become the sixth-largest company by market value in the United States, at least based on recent share prices.

Newly listed companies typically have to wait up to a year before becoming eligible for major indexes such as the Nasdaq-100 or S&P 500.

Inclusion in a major index can significantly broaden a company’s shareholder base because many institutional investors purchase shares through index-tracking funds.

According to Reuters, Nasdaq’s proposed fast-track rule is partly intended to attract highly valued private companies such as SpaceX, OpenAI, and Anthropic to list on the exchange.

Elon Musk shares nighttime view of latest Starbase in Texas

A striking nighttime photograph of SpaceX’s Starbase facility in Boca Chica, Texas, shared recently by Elon Musk on X, offers a dramatic glimpse of an operation that is rapidly transforming the southern tip of the Lone Star State into one of the most ambitious launch complexes in history.

The most immediately visible change in the photo is the presence of two fully erected Starship launch towers dominating the coastal skyline. The second orbital launch pad, known as Pad B, now features its fully erected tower, OLIT-3, which stands approximately 474 feet tall and incorporates an integrated water-cooled flame trench designed to minimize damage and reduce turnaround time between launches. The dual-tower silhouette against the night sky signals a decisive shift from experimental testing facility to high-cadence launch operations.

Back at Starbase, Pad 2 is approaching hardware completion, with upgraded chopstick arms, a new chilldown vent system, and all 20 hold-down arms now fitted with protective doors to shield them from the intense exhaust of up to 33 Raptor 3 engines, according to a deeper dive by NASASpaceFlight.

SpaceX has also received approval to nearly double the footprint of the Starbase launch site, with groundwork already underway to add LNG liquefaction plants, expanded propellant storage, and additional ground support infrastructure.

The photo also carries a milestone civic dimension. Starbase officially became a Texas city in May 2025 after a community vote, with SpaceX employees elected as mayor and commissioners of the newly incorporated municipality. That legal status streamlines launch approvals and gives SpaceX direct control over local infrastructure decisions.

The FAA has approved an increase in launches from Starbase in Texas from five to twenty-five per year, clearing the runway for the kind of flight frequency needed to fulfill Starship’s ultimate mission of ferrying cargo and crew to the Moon, servicing the Department of Defense, deploying next-generation Starlink satellites, and eventually establishing Elon Musk’s long sought after goal of a self-sustaining human presence on Mars.

Seen from above in the dark, Starbase looks less like a test site and more like a spaceport.
