NASA to roll SLS Moon rocket to the launch pad two days early
NASA has given the go-ahead to roll its Space Launch System (SLS) Moon rocket to the launch pad two days ahead of schedule.
That bodes well for plans to launch the rocket for the first time (a milestone NASA originally hoped to pass in December 2016) as early as late August or September 2022. NASA says that its first SLS rocket is now on track to begin a roughly 24-hour journey to Kennedy Space Center’s LC-39B launch pad at 9 pm EDT on August 16th. That will kick off approximately two more weeks of work that could finally culminate in the rocket’s first real launch attempt as early as August 29th, a moment anywhere from 12 to 16 years in the making.
SLS was created by Congress in 2010 when the legislative body drafted a law demanding that NASA develop a heavy-lift rocket to replace the Space Shuttle. In practice, Congress (particularly several key stakeholders with former Shuttle workforce and facilities in their states or districts) was primarily interested in keeping former Shuttle infrastructure active and workers employed, and left NASA to figure out how to retroactively engineer a rocket out of a list of legal requirements mostly driven by politics.
NASA ultimately devised a rocket that would extrapolate Shuttle external tank technology into a larger liquid hydrogen/oxygen ‘core stage’ powered by four flight-proven, reusable Space Shuttle Main Engines (SSME; now RS-25). A relatively small orbital upper stage derived from Boeing’s Delta IV rocket would sit atop the core stage, which would be augmented with two stretched Shuttle-derived solid rocket boosters (SRBs). Altogether, the first variant of SLS – Block 1 – is expected to be able to launch up to 95 tons (~210,000 lb) to low Earth orbit and around 27 tons (~59,500 lb) to the Moon, 32% and 38% worse than the Saturn V rocket NASA abandoned for the Space Shuttle in the 1970s.
Nevertheless, SLS will likely become the most powerful rocket currently in operation if it successfully debuts within the next few months. Only SpaceX’s Starship, which will eventually launch a Starship-derived Moon lander for NASA, is likely to challenge or beat the performance of SLS within the next 5-10 years.
However, after more than half a decade of delays and around $25 billion spent without a single launch to show for its investment, NASA no longer has any near-term plans to use SLS for more than sending a few astronauts on their way to the Moon once every year or two. The only tangible payload currently assigned to SLS Block 1 is NASA’s own Orion spacecraft, an earlier version of which Lockheed Martin began developing for NASA in 2006. Approximately 16 years and $25 billion later, the Orion capsule will be better than the Apollo Program’s Command module (capsule) by most measures, but its service (propulsion) module will be far worse.
With about half as much usable delta V (propulsive capability) as the Apollo CSM, Orion is incapable of transporting astronauts to the same convenient low lunar orbits that the Apollo Program used, forcing NASA to send it to high, exotic alternatives. As a result, NASA has been forced to create a multi-billion-dollar destination for Orion (the Gateway station) and complicate the mission of new Moon landers like SpaceX’s Starship.
Countless pitfalls and shortcomings aside, NASA is about to finally roll the fourth most capable flightworthy rocket ever assembled (behind Saturn V, N-1, and Energia) to the launch pad. Regardless of the outcome of the mission, SLS will likely be the fifth largest rocket (including the Space Shuttle) ever launched when it lifts off. If that launch is successful, the achievement will be even more impressive, marking the third time out of three attempts that NASA has successfully launched a super heavy-lift launch vehicle (>50t to LEO) on its first try.
A successful Artemis I launch would also give the Orion spacecraft an opportunity to enter orbit around the Moon and test most of the systems it will need for Artemis II, which is intended to carry two astronauts. Orion won’t carry or test any life support or docking systems, making it only a partial demonstration, but it will still be the first time a prototype of a crewed spacecraft has attempted to enter lunar orbit since December 1972.

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.
