Years before the space agency’s flagship Europa Clipper mission is scheduled to lift off, NASA and SpaceX are already determining the specifics of the launch – including which Falcon Heavy boosters will support it.
On July 23rd, 2021, after years of rumors, NASA officially announced that it no longer planned to launch Europa Clipper on its own SLS rocket and would instead contract with SpaceX to send the spacecraft to Jupiter on a Falcon Heavy. In terms of sheer prestige, no other mission on Falcon Heavy’s manifest comes close. Expected to weigh around six tons (~13,000 lb), Europa Clipper is a building-sized spacecraft that aims to orbit Jupiter for years, performing dozens of flybys of the planet’s icy moons – several of which almost certainly have liquid oceans.
Europa – the mission’s namesake – is its primary focus and whether or not the funding or political motivation for such an ambitious mission transpires, Europa Clipper was always partially meant to be a scouting mission for a nuclear-powered lander. On its own, though, Clipper has already blown past its original $2B budget target from 2013 and is now on track to cost more than $4.5B, making it the most expensive NASA mission currently in development – second only to the ~$9B James Webb Space Telescope (JWST). In other words, NASA is entrusting SpaceX to launch what is perhaps the most expensive mission to the outer solar system in the history of planetary exploration.
That makes it all the more noteworthy that NASA has already given the okay for SpaceX to plan to launch Europa Clipper on a Falcon Heavy rocket with at least two of its three boosters already flight-proven. According to mission scientist Bob Pappalardo, Clipper Mission Design Lead Brett Buffington revealed in spacecraft “System Integration Review” that SpaceX intends to reuse two Falcon Heavy side boosters that are currently scheduled to debut as early as next year on a different NASA mission. Known as Psyche, that mission – also scheduled to fly on Falcon Heavy – is scheduled to launch no earlier than (NET) August 2022 and is designed to explore an asteroid that’s believed to be almost entirely composed of metal.
With Europa Clipper scheduled to launch NET October 2024, that undoubtedly makes this the earliest a Falcon booster assignment has ever been confirmed – and probably the earliest SpaceX itself has assigned flight-proven boosters to a specific mission. It also makes those particular boosters quite special. Unlike Psyche, which will leave plenty of margin for SpaceX to recover at least two of Falcon Heavy’s three boosters, Europa Clipper will need almost every ounce of performance the rocket can give to send the much larger spacecraft much faster and further. Barring a major surprise, that means that Falcon Heavy will launch Europa Clipper in a fully expendable configuration.
For SpaceX, being able to use at least two flight-proven proven boosters on that expendable mission will make expending two Falcon Heavy boosters – which are otherwise capable of launching at least ten times in their lifetimes – a much easier pill to swallow. For NASA, the space agency is likely already familiar with the reality that flight-proven hardware actually improves schedule confidence, which is crucial for a mission like Europa Clipper thanks to its 21-day launch window.
Nonetheless, it does still raise the question of whether NASA will allow SpaceX to fly Psyche’s Falcon Heavy side boosters once or even twice more in the more than two years they’ll otherwise have to spend in storage between Psyche and Europa Clipper. A Falcon Heavy rocket is currently scheduled to launch a commercial Moon lander and NASA’s VIPER Moon rover as early as Q4 2023. Most recently, NASA purchased a Falcon Heavy to launch NOAA’s GOES-U weather satellite NET Q2 2024. In 2022 alone, SpaceX also has at least three other non-NASA missions scheduled to launch before Psyche, raising another possibility that Psyche itself might fly on once-flown boosters that would then fly a third, fourth, or even fifth time with Europa Clipper.
That might seem like an unlikely possibility but NASA has already shown that it’s happy to launch Cargo Dragons on boosters with multiple non-NASA missions in their pasts and will soon launch DART – an asteroid impact spacecraft – on another Falcon booster that last launched Starlink satellites. Additionally, with Arabsat 6A and STP-2, SpaceX already demonstrated in 2019 that it can launch Falcon Heavy, recover its two side boosters, and relaunch those same boosters on a different Falcon Heavy mission less than two months later – and for the US military, no less.

Tesla removes Model S and X custom orders as sunset officially begins
In a significant development that marks the beginning of the end for two of its longest-running models, Tesla has removed the custom order configurator for the Model S sedan and Model X SUV from its website.
Tesla has officially started the “honorable discharge” of the Model S and Model X with a massive move, removing the two vehicles from Custom Orders and only offering inventory options.
It is the latest move Tesla has made to pull the Model S and Model X from its lineup, a decision CEO Elon Musk announced during its last quarterly earnings call.
Tesla brings closure to flagship ‘sentimental’ models, Musk confirms
In a significant development that marks the beginning of the end for two of its longest-running models, Tesla has removed the custom order configurator for the Model S sedan and Model X SUV from its website.
As of April 1, visitors to tesla.com/model-s and tesla.com/modelx are now redirected exclusively to limited inventory listings rather than a design studio, allowing buyers to select paint, wheels, interior options, or performance upgrades. Only pre-built vehicles currently in stock are available for purchase or lease.
Tesla CEO Elon Musk confirmed the change directly on X, posting: “Custom orders of the Tesla Model S & X have come to an end. All that’s left are some in inventory.”

We will have an official ceremony to mark the end of an era.” Accompanying the statement was a throwback photo from the Model S production launch in 2012, underscoring the emotional weight of the decision.
Musk had first signaled the phase-out during the company’s Q4 2025 earnings call in January, describing it as time for an “honorable discharge” of the programs to free up resources at the Fremont factory for Optimus humanoid robot production and autonomous vehicle initiatives.
The Model S, introduced in 2012, and the Model X, which followed in 2015, were instrumental in establishing Tesla as a premium electric vehicle leader.
The sedan offered class-leading range and acceleration, while the SUV’s signature falcon-wing doors became an iconic feature. Together, they proved EVs could compete in the luxury segment. Yet sales volumes have dwindled in recent years as Tesla prioritized higher-volume Model 3 and Model Y vehicles.
The flagships now represent a tiny fraction of overall deliveries, making continued custom production inefficient as the company accelerates toward robotaxis and next-generation platforms.
Prospective buyers are urged to act quickly. Remaining U.S. inventory vehicles—some nearly new—may include incentives such as lifetime free Supercharging, Full Self-Driving (Supervised) capability, and premium connectivity, depending on configuration.
Leasing options start around $1,699 per month for select Model X units, though exact pricing and availability fluctuate. International markets, including Europe and China, have already seen similar restrictions in recent months.
The move aligns with Tesla’s broader strategy to streamline its lineup and redirect manufacturing capacity toward autonomy and AI-driven products. While some enthusiasts lament the loss of personalization, the company views the transition as necessary progress.
Tesla has indicated that once the current inventory sells out, new Model S and Model X vehicles will no longer be offered.
For loyal owners and fans, the promised “official ceremony” may provide a fitting send-off. In the meantime, the website change serves as a clear signal: the era of bespoke flagship Teslas has quietly concluded, and the focus has fully shifted to the future.

SpaceX files confidentially for IPO that will rewrite the record books
SpaceX files confidentially for a record-breaking IPO targeting a $1.75T valuation and $80B raise, driven by Starlink growth and its xAI merger.
Elon Musk’s rocket and satellite company submitted its draft registration to the U.S. Securities and Exchange Commission today for an initial public offering, targeting June at a $1.75 trillion valuation. This would be the largest in history.
SpaceX has filed confidentially with the SEC, first reported by Bloomberg. SpaceX would be valued above every S&P 500 company except Nvidia, Apple, Alphabet, Microsoft, and Amazon.
The filing uses a confidential process that allows companies to work through SEC disclosures privately before initiating a public roadshow. With a June target, official details through a formal prospectus is expected to go public in April or early May, after which SpaceX must wait at least 15 days before beginning investor marketing.
While SpaceX is best known for its Falcon 9 and Starship rockets, the $1.75 trillion valuation is anchored by Starlink, its satellite internet service. Starlink ended 2025 with 9.2 million subscribers and over $10 billion in revenue, which is a figure analysts project could reach a staggering $24 billion by the end of 2026. A February all-stock merger with xAI, Musk’s artificial intelligence venture, further boosted the valuation.

Bank of America, Goldman Sachs, JPMorgan Chase, and Morgan Stanley are lined up as senior underwriters. SpaceX is also considering a dual-class share structure to preserve insider voting control, and plans to allocate up to 30% of shares to retail investors, which is roughly three times the typical norm.

Elon Musk hints at “official ceremony” with throwback photo to close Tesla Model S, Model X chapter
Elon Musk promises an official ceremony to mark the end of Tesla Model S and Model X production.
Tesla has officially begun winding down production of the Model S and Model X, sending farewell emails to U.S. customers on March 27 and updating the website to reflect the end of the line. Shoppers visiting Tesla.com now find only a limited set of Model S and Model X inventory units available for purchase, with no option to configure a new factory build. The move formalizes what CEO Elon Musk announced on the company’s Q4 2025 earnings call in January, when he said it was “time to basically bring the Model S and X programs to an end with an honorable discharge.”
Musk posted on X a throwback photo of himself speaking at the Model S production launch in 2012, and noting “We will have an official ceremony to mark the ending of an era. I love those cars.”
The mention of an official ceremony is notable. Tesla has not held a formal farewell event for a vehicle before, and Musk’s wording suggests this will be something deliberate rather than a quiet line shutdown. Given that Musk’s X post shows a photo of him on stage with a microphone in front of an audience at the Fremont factory, it wouldn’t be too far-fetched to expect a closing ceremony to take place at the same location. Perhaps? Whether it becomes a public event, a private gathering for employees, or a livestreamed moment on X remains to be seen.

The Model S first went on sale nearly fifteen years ago and was Tesla’s first fully in-house designed vehicle, proving that an electric car could be fast, desirable, and capable of long distance on a single charge. The Model X followed in 2015, turning heads with its unmistakable and distinctive falcon-wing doors, while becoming one of the first all-electric SUVs on the market. Tesla’s two flagship vehicles would ultimately push legacy automakers to take all-electric transportation seriously and help fund development of the more affordable Model 3 and Model Y.
By 2025, however, both models had been reduced to a rounding error in Tesla’s sales figures. Musk was direct about what comes next, stating “We are going to convert that production space to an Optimus factory. It’s part of our overall shift to an autonomous future.”

That shift is already underway. Tesla officially started Optimus Gen 3 production at its Fremont factory in January 2026, with the line targeting a run rate of one million units per year. The Gen 3 robot features 22 degrees of freedom per hand, runs on Tesla’s AI5 chip, and shares the same neural network architecture as Full Self-Driving. A dedicated Optimus factory at Gigafactory Texas is also under construction, with a planned annual capacity of 10 million units. The production lines that once built the Model S and Model X are being converted to support that ramp.
Tesla confirmed it will continue to support existing owners with service, software updates, and parts for as long as people own the vehicles. For buyers still interested in a new example, remaining U.S. inventory is discounted and the window is closing fast.
