SpaceX preparing for third Starship ‘full stack’
SpaceX appears to be preparing Starship 20 and Super Heavy Booster 4 for their third ‘full stack’ demonstration after two seemingly successful tests in August 2021 and February 2022.
The first, completed in early August 2021, was mostly for show and saw SpaceX stack the unfinished prototypes with a giant crane – fighting the coastal winds throughout. After just a few hours stacked, Ship 20 was removed and returned to Starbase, where workers spent several more weeks (mostly) finishing the prototype. Booster 4 followed suit several weeks later and ultimately took another three months of work to reach some level of test readiness.
After Ship 20 and Booster 4 completed a series of tests in the last few months of 2021 and early 2022, the two were re-stacked in mid-February – once again for show. This time, the stacked Starship served as a backdrop for SpaceX CEO Elon Musk’s first official Starship presentation in more than two years. However, despite the fact that neither prototype was actually tested during the second stack, SpaceX did use the opportunity to partially debut Starbase’s ‘orbital launch integration tower’ and used that towers trio of giant arms to lift, stack, and stabilize Starship S20 on top of Super Heavy B4.
Ship 20 was ‘destacked’ with the tower’s arms just a few days after Musk’s event – an undeniably rapid and impressive achievement for the first real use of the ‘chopstick’ arms but still far from demonstrating that Ship 20, Booster 4, or the orbital launch site (OLS) are ready for orbital test flights. Since then, however, Starbase’s launch facilities have admittedly been almost as busy as they’ve ever been with Starship and Super Heavy cryoproof tests.
Ship 20 completed its first basic OLS cryogenic proof test or ‘cryoproof’ just two days after it was destacked. Additional Starship S20 cryoproofs followed on February 17th (the day after), February 22nd, and March 3rd. Super Heavy B4 completed its own cryoproofs on February 18th and March 1st, the latter of which may have actually been the fullest a Starship booster has ever been filled. All told, SpaceX completed no less than six major B4/S20 cryoproof tests in 15 days.
Crucially, all six cryoproofs were performed with Starbase’s nascent orbital tank farm, thoroughly testing its storage and distribution capabilities. Additionally, because SpaceX began liquid methane deliveries on February 13th, some of those tests – particularly with Ship 20 – may have even been proper wet dress rehearsals, meaning that SpaceX may have filled the rocket(s) with liquid methane (LCH4) and liquid oxygen (LOx) propellant to replicate preparations for a real launch.
At a minimum, Super Heavy Booster 4’s oxidizer tank was fully filled with liquid oxygen – and possibly pressurized with hot gaseous oxygen – during its March 1st cryoproof, while its fuel tank was filled about two-thirds of the way either with liquid nitrogen (LN2) or methane. Prior to its February and March tests, Booster 4 had already completed three cryoproofs – some also using LOx – in December 2021. Ship 20 had completed a cryoproof and four static fire tests.
All told, short of finally performing a full Super Heavy wet dress rehearsal and static fire at the orbital launch site, it’s not all that clear what more SpaceX can derive from additional individual cryoproof testing of Ship 20 or Booster 4. Several things do still need to be demonstrated, however. First, the OLS launch tower has yet to use its arms to remotely install a Super Heavy on the orbital launch mount. More importantly, SpaceX has yet to use the launch tower and its swinging ship umbilical arm to cryoproof or fuel a Starship while stacked on top of a Super Heavy. Finally, SpaceX has also yet to simultaneously perform a cryoproof or wet dress rehearsal test of a stacked Starship and Super Heavy, which will be necessary for orbital test flights.
One or several of those to-be-completed tests may be why SpaceX appears to have begun preparing to install Ship 20 on top of Booster 4 for the third time. On March 14th, Starship S20 was moved towards the launch tower and on March 15th, the ship was slotted between its ‘chopstick’ arms. Based on stack #2, the ship could be lifted at any point – day or night – and installed on top of Super Heavy in a matter of hours.

Tesla ‘Killer’ heads to the graveyard as AFEELA taps out
SHM has officially discontinued development of its highly anticipated AFEELA electric vehicles. On March 25, the joint venture between Sony and Honda announced it would halt the AFEELA 1 luxury sedan and a planned SUV model.
There have been many Tesla “Killers” over the years, all of which have either failed to dethrone the automaker from its dominance in the United States, or even make it to the market altogether.
The Sony Honda Mobility (SHM) project, known as AFEELA, is the latest to make it to the grave, as the company announced its intentions to abandon the project earlier this week, Bloomberg reported.
SHM has officially discontinued development of its highly anticipated AFEELA electric vehicles. On March 25, the joint venture between Sony and Honda announced it would halt the AFEELA 1 luxury sedan and a planned SUV model.

Stylish SUV with solar roof promises. Company filed for bankruptcy in 2024 amid… https://t.co/Om14UhISOy— TESLARATI (@Teslarati) March 26, 2026
The decision follows Honda’s March 12 reassessment of its electrification strategy, which scrapped several upcoming EV programs amid slowing demand, high costs, and shifting market conditions.
SHM stated that it could no longer rely on key Honda technologies and manufacturing assets, leaving “no viable path forward.” Reservation fees for early buyers in California are being fully refunded, and the joint venture’s future is now under review.
Launched with fanfare in 2022, the AFEELA was positioned as a tech-forward premium EV blending Honda’s engineering reliability with Sony’s entertainment and AI expertise.
Prototypes featured advanced autonomous driving systems, immersive in-cabin displays, and even PlayStation integration, earning it early media labels as a potential “Tesla Killer.”
Priced around $90,000, the sedan was slated for limited production at Honda’s Ohio plant with deliveries targeted for late 2026. Industry watchers saw it as a serious challenger to Tesla’s dominance in software, connectivity, and premium appeal.
Yet, like many ambitious EV projects, it fell victim to broader industry headwinds: softening consumer demand, persistent high interest rates, and intense competition from established players.
The AFEELA joins a long list of vehicles once hyped as “Tesla Killers” that failed to deliver. In the late 2010s, Fisker’s second act, the Ocean SUV, promised stylish design and solid-state battery tech but collapsed into bankruptcy in 2024 after production delays, quality issues, and financial shortfalls.
Faraday Future poured billions into the FF 91 luxury sedan, touting it as a hyper-tech rival with unmatched performance and features; the company delivered fewer than 100 vehicles before fading into obscurity.
Lordstown Motors’ Endurance electric pickup generated massive pre-order buzz and Wall Street excitement but imploded after exaggerated range claims, a factory sale, and eventual bankruptcy.
Even Lucid Motors’ Air sedan, frequently called a Tesla slayer for its superior range and luxury, has struggled with sluggish sales and missed growth targets despite strong reviews.
Rivian’s R1T and R1S trucks enjoyed similar early acclaim and a blockbuster IPO, yet production ramp-up challenges and profitability woes have prevented it from dethroning Tesla.
The AFEELA’s quiet demise underscores a harsh reality in the EV sector. While Tesla’s first-mover advantage in software, charging infrastructure, and brand loyalty remains formidable, legacy automakers and tech newcomers alike continue to underestimate the complexities of scaling affordable, desirable electric vehicles.
As market realities force tough choices, the graveyard of “Tesla Killers” grows longer, another reminder that innovation alone is rarely enough to topple an established leader.

TIME honors SpaceX’s Gwynne Shotwell: From employee No. 7 to world’s most valuable company
Time Magazine honors Gwynne Shotwell as SpaceX reaches a $1.25 trillion valuation and eyes its IPO.
TIME Magazine has put SpaceX President and COO Gwynne Shotwell on its cover, and the timing could not be more fitting. Published today, the profile of Shotwell arrives at a moment when the company she has quietly run for more than two decades stands at the center of the most consequential developments in aerospace, artificial intelligence, and the future of human civilization.
Shotwell joined SpaceX in 2002 as its seventh employee and has never stopped expanding her role. She oversees day-to-day operations across multiple executive teams spanning Falcon, Starlink, Starship, and now xAI following SpaceX’s February 2026 merger with Elon Musk’s artificial intelligence company, a deal that made SpaceX the world’s most valuable private company at a reported valuation of $1.25 trillion. A highly anticipated IPO is expected in the second quarter of 2026.
Will Tesla join the fold? Predicting a triple merger with SpaceX and xAI
Her track record is historic. She oversaw the first landing of an orbital rocket’s first stage, the first reuse and re-landing of an orbital booster, and the first private crewed launch to Earth orbit in May 2020. She built the Falcon launch manifest from nothing to more than 170 contracted missions representing over $20 billion in business. Under her operational leadership, SpaceX completed 96 successful missions in 2023 alone and has now flown more than 20 crewed Falcon 9 missions. Starlink, which she championed as a financial pillar of the company long before it was a mainstream topic, now connects tens of millions of users worldwide and provided a critical communications lifeline to Ukraine following the 2022 invasion.
Elon Musk has never been shy about what Shotwell means to him and to SpaceX. When she shared her vision for worldwide internet connectivity through Starlink, Musk responded on X with a simple statement, “Gwynne is awesome.” It is a sentiment that has been echoed across the industry. NASA Administrator Bill Nelson once said of Musk: “One of the most important decisions he made, as a matter of fact, is he picked a president named Gwynne Shotwell. She runs SpaceX. She is excellent.”

Now, with Starship targeting its first crewed lunar landing under the Artemis program by 2028, an xAI integration underway, and a pending IPO that could reshape capital markets, Shotwell’s mandate has never been larger. She told Time that 18 Starships are already in various stages of construction at Starbase. “By 2028,” she said, gesturing across the factory floor, “these should be long gone. They better have flown by then.” If Shotwell’s history at SpaceX is any guide, they will.

SpaceX’s IPO might arrive sooner than you think
Musk has hinted for years that an eventual public offering was inevitable, though he has stressed the need to maintain operational focus. Insiders have told outlets that the CEO is pushing for a significant retail investor allocation, reportedly more than 20 percent of shares, and tighter lock-up periods to limit early selling pressure.
Elon Musk’s SpaceX is on the verge of one of the most anticipated Initial Public Offerings (IPO) in history.
However, a new report from The Information indicates the rocket and satellite giant is aiming to file its IPO prospectus with U.S. regulators as soon as this week, or early next week at the latest.
People familiar with the plans told The Information that advisers involved in the process expect the IPO could raise more than 75 billion dollars, potentially making it the largest stock market debut ever and eclipsing Saudi Aramco’s 29.4 billion dollar offering in 2019.
The filing would mark the formal start of what has long been rumored: SpaceX’s transition from a closely held private powerhouse to a publicly traded company.
The timing aligns with earlier signals.
In late February, Bloomberg reported that SpaceX was targeting a confidential IPO filing in March and a possible public listing in June, with a valuation north of 1.75 trillion dollars. At the time, the company’s private valuation hovered around 1.25 trillion dollars.
SpaceX considering confidential IPO filing this March: report
Starlink, SpaceX’s satellite internet constellation, has been the primary driver of that surge, now serving millions of customers worldwide and generating steady revenue. Recent Starship test flights and a record pace of Falcon launches have further bolstered investor confidence.

Insiders have told outlets that the CEO is pushing for a significant retail investor allocation, reportedly more than 20 percent of shares, and tighter lock-up periods to limit early selling pressure.
A June listing would give SpaceX immediate access to public capital markets at a moment when demand for space-related stocks remains high. It would also allow early employees and long-time investors to cash out portions of their stakes while giving everyday shareholders a chance to own a piece of the company behind reusable rockets, global broadband, and NASA contracts.
Of course, nothing is certain until the SEC filing appears. Market conditions, regulatory reviews, and Musk’s own schedule could still shift timelines.
Yet the latest word from The Information suggests the window has opened. If the filing lands this week, SpaceX’s roadshow could begin in earnest within weeks, setting the stage for what many analysts already call the IPO of the decade.
