SpaceX tweaks Starship's Super Heavy rocket booster as design continues to evolve

CEO Elon Musk says that SpaceX continues to evolve the design of its next-generation Starship spacecraft and Super Heavy rocket booster, a process of continuous improvement the company has successfully used for a decade.

Designed to place more than 100 metric tons (220,000 lb) of payload into Low Earth Orbit (LEO), Starship would effectively double (and possibly triple) the expendable performance of SpaceX’s existing Falcon Heavy rocket. Critically, it would be able to dramatically outclass Falcon Heavy (and Falcon 9 even more so) in a fully reusable configuration, meaning that both the Starship upper stage and Super Heavy booster could be recovered and reused.

Since SpaceX first publicly revealed its next-generation launch vehicle and Mars ambitions in September 2016, the path to realizing the dream of a fully-reusable super heavy-lift launch vehicle has been decidedly windy. After making the radical decision to move entirely from carbon composites to stainless steel in late 2018, the Starship design has remained relatively similar, coalescing around a specific concept that has matured to full-scale tank tests. Now, Musk says that Super Heavy’s design was tweaked slightly to make the booster even taller than before, while he later noted that Starship’s design also continues to “[evolve] rapidly.”

According to Musk, the Super Heavy booster will be stretched by a steel ring or two, reaching a new height of ~70m (230 ft). In other words, Starship’s first stage alone will measure as tall as the entirety of a Falcon 9 or Falcon Heavy rocket – first stage, second stage, and payload fairing included. Powered by up to 37 Raptor engines, a Super Heavy booster could produce more than ~90,000 kN (19,600,000 lbf) of thrust at liftoff – an incredible 12 times as much thrust as SpaceX’s workhorse Falcon 9 rocket.

Starship, meanwhile, will be a beast of an orbital-class upper stage on its own, measuring at least 50m (165 ft) tall and weighing some 1350 metric tons (3 million lb) fully-fueled. Stacked on top of Super Heavy, a Starship ‘stack’ would reach a staggering 120m (395 ft) and weigh more than 5000 metric tons (11 million lb) once loaded with liquid oxygen and methane propellant.

In simple terms, Starship/Super Heavy should be the tallest, heaviest, and most powerful launch vehicle ever assembled once it heads to the launch pad for the first time. While SpaceX is making great daily progress its ever-growing South Texas rocket factory, built up from next to nothing in a matter of months, it could still be quite some time before that milestone is within reach.

SpaceX’s process of continuously tweaking and improving the design and production of its rockets does typically have that effect. However, it’s more a symptom of the company’s approach to hardware and software development. Instead of working slowly and carefully from nothing to a preconceived finished product, SpaceX typically seeks to design, build, and test the minimum viable product, gradually improving (or entirely replacing) past ideas, designs, and hardware until overarching goals are fully achieved.

With Falcon 9 and Falcon Heavy, this meant beginning with Falcon 1, a dead-simple proof-of-concept rocket. After successfully reaching orbit, SpaceX expanded its Falcon 9 development program, itself focused initially on the minimum viable product – a full-scale expendable rocket. Since Elon Musk founded SpaceX in 2002, the goal has always been to build a fully-reusable rocket – the company has simply chosen the far more sustainable and practical approach of tackling only a select few problems at a time.

The Starship and Falcon development programs aren’t directly comparable but it’s safe to say that Starship is currently still in the very early stages of hardware development. Shortly after revealing Super Heavy’s height growth, Musk noted that Starship’s design is also being tweaked.

Sketching out a rough series of upgrades that could feasibly be made to the reusable spacecraft’s currently design, Musk thinks that Starship’s conical tank domes (and thus Super Heavy’s, too) could be flattened. That might allow an extra ~3m (10 ft) of propellant tank space to be squeezed into the same 50m Starship length, improving performance by simply using the vehicle’s fixed volume more efficiently.

With a nascent factory quite literally churning out Starship hardware, these tweaks are a whole different animal. Thanks to data and insight gathered from testing actual full-scale Starship tanks, up to and including fully-assembled tank sections, SpaceX will be able to guide its continuous improvement with even greater precision, honing in on the next-generation rocket’s orbital launch debut.

Tesla is making two big upgrades to the Model 3, coding shows

According to coding found in the European and Chinese configurators, Tesla is planning to make two big upgrades: Black Headliner offerings and a new 16-inch QHD display, similar to that on the Model Y Performance.

Tesla is making two big upgrades to the Model 3, one of which is widely requested by owners and fans, and another that it has already started to make on some trim levels of other models within the lineup.

The changes appear to be taking effect in the European and Chinese markets, but these are expected to come to the United States based on what Tesla has done with the Model Y.

According to coding found in the European and Chinese configurators, Tesla is planning to make two big upgrades: Black Headliner offerings and a new 16-inch QHD display, similar to that on the Model Y Performance.

These changes in the coding were spotted by X user BERKANT, who shared the findings on the social media platform this morning:

It appears these new upgrades will roll out with the Model 3 Performance and Tesla’s Premium trim levels of the all-electric sedan.

The changes are welcome. Tesla fans have been requesting that its Model 3 and Model Y offerings receive a black headliner, as even with the black interior options, the headliner is grey.

Tesla recently upgraded Model Y vehicles to this black headliner option, even in the United States, so it seems as if the Model 3 will get the same treatment as it appears to be getting in the Eastern hemisphere.

Tesla has been basically accentuating the Model 3 and Model Y with small upgrades that owners have been wanting, and it has been a focal point of the company’s future plans as it phases out other vehicles like the Model S and Model X.

Additionally, Tesla offered an excellent 0.99% APR last week on the Model 3, hoping to push more units out the door to support a strong Q1 delivery figure at the beginning of April.

SpaceX secures FAA approval for 44 annual Starship launches in Florida

The FAA’s environmental review covers up to 44 launches annually, along with 44 Super Heavy booster landings and 44 upper-stage landings.

SpaceX has received environmental approval from the Federal Aviation Administration (FAA) to conduct up to 44 Starship-Super Heavy launches per year from Kennedy Space Center Launch Complex 39A in Florida. 

The decision allows the company to proceed with plans tied to its next-generation launch system and future satellite deployments.

The FAA’s environmental review covers up to 44 launches annually, along with 44 Super Heavy booster landings and 44 upper-stage landings. The approval concludes the agency’s public comment period and outlines required mitigation measures related to noise, emissions, wildlife, and airspace management.

Construction of Starship infrastructure at Launch Complex 39A is nearing completion. The site, previously used for Apollo and space shuttle missions, is transitioning to support Starship operations, as noted in a Florida Today report.

If fully deployed across Kennedy Space Center and nearby Cape Canaveral Space Force Station, Starship activity on the Space Coast could exceed 120 launches annually, excluding tests. Separately, the U.S. Air Force has authorized repurposing Space Launch Complex 37 for potential additional Starship activity, pending further FAA airspace analysis.

The approval supports SpaceX’s long-term strategy, which includes deploying a large constellation of satellites intended to power space-based artificial intelligence data infrastructure. The company has previously indicated that expanded Starship capacity will be central to that effort.

The FAA review identified likely impacts from increased noise, nitrogen oxide emissions, and temporary airspace closures. Commercial flights may experience periodic delays during launch windows. The agency, however, determined these effects would be intermittent and manageable through scheduling, public notification, and worker safety protocols.

Wildlife protections are required under the approval, Florida Today noted. These include lighting controls to protect sea turtles, seasonal monitoring of scrub jays and beach mice, and restrictions on offshore landings to avoid coral reefs and right whale critical habitat. Recovery vessels must also carry trained observers to prevent collisions with protected marine species.

The Woodlands Township, Texas, has formally entered The Boring Company’s tunneling sweepstakes. 

The township’s board unanimously approved an application to The Boring Company’s “Tunnel Vision Challenge,” which offers up to one mile of tunnel construction at no cost to a selected community.

The Woodlands’ proposal, dubbed “The Current,” features two parallel 12-foot-diameter tunnels beneath the Town Center corridor near The Waterway. Teslas would shuttle passengers between Waterway Square, Cynthia Woods Mitchell Pavilion, Town Green Park and nearby hotels during concerts and large-scale events, as noted in a Chron report.

Township officials framed the tunnel as a solution for the township’s traffic congestion issues. The Pavilion alone hosts more than 60 shows each year and can accommodate crowds of up to 16,500, often straining Lake Robbins Drive and surrounding intersections.

“We know we have traffic impacts and pedestrian movement challenges, especially in the Town Center area,” Chris Nunes, chief operating officer of The Woodlands Township, stated during the meeting.

“The Current” mirrors the Loop system operating beneath the Las Vegas Convention Center, where Tesla vehicles transport passengers through underground tunnels between venues and resorts.

The Boring Company issued its request for proposals (RFP) in mid-January, inviting cities and districts to pitch local uses for its tunneling technology. The Woodlands must submit its application by Feb. 23, though no timeline has been provided for when a winning community will be announced.

Nunes confirmed that the board has authorized a submission for “The Current’s” proposal, though he emphasized that the project is still in its preliminary stages.

“The Woodlands Township Board of Directors has authorized staff to submit an application to The Boring Company, which has issued an RFP for communities interested in leveraging their technology to address community challenges,” he said in a statement. 

“The Board believes that an underground tunnel would provide a safe and efficient means to transport people to and from various high-use community amenities in our Town Center.”
