SpaceX Falcon Heavy rocket celebrates 4th launch debut anniversary

Published

on

On the fourth anniversary of SpaceX’s Falcon Heavy launch debut and after an unusual multi-year hiatus, the world’s most powerful operational rocket could be on the brink of an impressive salvo of launches.

Four years ago yesterday, on February 6th, 2018, Falcon Heavy lifted off from NASA’s historic Kennedy Space Center (KSC) Pad 39A launch complex, launched a truly esoteric payload into interplanetary space, and officially became the largest, heaviest, and most powerful active launch vehicle in the world. It also became the third most powerful liquid rocket ever launched, placing SpaceX squarely at the table alongside the likes of NASA’s Saturn V Moon rocket and the Soviet Union’s ill-fated N-1 and Energia.

14 months later, an upgraded “Block 5” version of Falcon Heavy aced two more back-to-back launches in April and June 2019, completing its first missions for paying customers and also aiding the US Air Force in its efforts to certify the capable rocket for high-value military launches. However, such an auspicious beginning made the years of inactivity that immediately followed Falcon Heavy’s third launch even more striking.

Since Falcon Heavy’s late-June 2019 launch of the USAF’s Space Test Program 2 (STP-2) mission, the rocket hasn’t launched once. That wasn’t supposed to be the case. As of June 2018, SpaceX was supposed to launch the US Air Force’s AFSPC-52 (now USSF-52) mission in September 2020. In June 2019, Spaceflight Now reported that USSF-44 – not USSF-52 – would be SpaceX’s next Falcon Heavy launch and was expected no earlier than (NET) “late 2020.” By September 2020, USSF-44 was expected to launch in February 2021. By February 2021, the US military stated that USSF-44 was scheduled to launch NET October 2021. By October 2021, the US military had once again delayed USSF-44 to early 2022 and USSF-52 to “Q2 2022.”

While the military has done little more than acknowledge each new date, it has vaguely implied that the spacecraft – not SpaceX – are to blame for the chronic, prolonged delays. Without even a hint of an explanation, it’s unclear if those delays are likely to end anytime soon, potentially delaying USSF-44 and USSF-52 into the second half or last quarter of 2022 and pushing USSF-67 into 2023. Thankfully, unreliable US military payloads aren’t the only Falcon Heavy missions scheduled this year.

At a minimum, SpaceX is contracted to launch the ViaSat’s first of three next-generation ViaSat-3 communications satellite directly to geostationary orbit (GEO). The launch was recently delayed from Q2 to the end of Q3 2022. SpaceX is also scheduled to launch NASA’s Psyche mission – a spacecraft designed to visit and study an asteroid made almost entirely out of metal – NET August 2022. While customer Inmarsat has yet to finalize or announce a contract decision, Falcon Heavy could potentially be tasked with launching the second Inmarsat-6 geostationary communications satellite sometime later this year.

All told, if every customer is able to stem each torrent of delays, Falcon Heavy could feasibly launch five or even six times in 2022. More conservatively, if USSF-67 and ViaSat-3 are delayed to 2023 and Inmarsat-6 F2 goes to Falcon 9, the world’s largest operational rocket could still launch three times in 2022 and still have up to three more launches scheduled next year.

For now, Falcon Heavy’s first launch in at least 33 months and fourth launch overall isn’t expected until March 2022 at the earliest.

The Tesla and SpaceX merger everyone is talking about is quietly building

Tesla and SpaceX may be closer to merging than Wall Street or either company is admitting.

Published

Elon Musk has reportedly discussed merging Tesla and SpaceX with people close to him, according to CNBC, which cited sources familiar with the conversation. Tesla employees have long expected such a transaction and the topic is openly discussed internally, according to internal sources. With SpaceX is days away from kicking off its Wall Street roadshow for what could be the largest IPO in market history, this would be the first time the company will have public market currency to execute a stock-for-stock deal with Tesla.

The financial logic for a merger would make sense. A combined SpaceX and Tesla would create a conglomerate spanning rockets, satellites, electric vehicles, AI infrastructure, and energy storage valued at roughly $3.35 trillion to $3.6 trillion based on SpaceX’s IPO target range and Tesla’s current market capitalization. The two companies are already more intertwined than most people realize. SpaceX bought $697 million worth of Tesla Megapack systems for xAI data centers and $131 million worth of Cybertrucks. Tesla invested $2 billion in xAI, which subsequently merged with SpaceX. Past transactions also include Tesla selling solar equipment and parts to SpaceX, and SpaceX helping with Cybertruck materials.

Will Tesla join the fold? Predicting a triple merger with SpaceX and xAI

Musk himself signaled where this was heading in November 2025 when he posted on X, “My companies are, surprisingly in some ways, trending towards convergence.” Tesla and SpaceX announced a joint semiconductor fabrication facility in Austin called Terafab on the Gigafactory Texas campus, covering two advanced chip factories, with one serving Tesla’s AI needs for vehicles and Optimus robots, the other targeting space-based data centers under SpaceX’s infrastructure vision.

Wedbush analyst Dan Ives places the probability of a merger at 80% to 90% with a target completion in the first half of 2027. The mechanics of a deal became possible the moment SpaceX filed its S-1. Legal experts said a merger likely would not spark antitrust issues but would raise concerns among shareholders in each company, with questions around which company would be the parent, how a stock swap would take place, and who determines the appropriate price. Musk holds about 20% of Tesla’s equity but controls 85.1% of SpaceX’s voting power through a super-voting share class, meaning he would largely be negotiating the terms with himself.

Elon Musk explains why he cannot be fired from SpaceX

Not everyone is convinced the timing is imminent. Traders on Kalshi place only 33% odds that a merger will happen before May 2027. The more immediate concern for Tesla shareholders is whether the SpaceX IPO pulls capital and Musk’s attention away from Tesla before any merger consolidates the upside for both.

What is clear is that the structural groundwork is already being laid. The Terafab announcement, the xAI merger, the shared supply chain, the cross-company balance sheet transactions, and now the IPO all point in the same direction. Whether the merger follows in 2027 or later, the two companies are already operating more like divisions of a single entity than independent competitors.

SpaceX to become America’s Military data backbone for missiles, drones, and warfighters

The Space Force just handed SpaceX $2.29 billion to build the military’s space internet backbone.

The U.S. Space Force awarded SpaceX a $2.29 billion contract on May 26, 2026 to build the backbone of its Space Data Network, a satellite-based communications system designed to keep American military forces connected anywhere on Earth in real time. The contract is firm-fixed-price and requires SpaceX to deliver a fully operational prototype by the end of 2027.

In plain terms, the SDN Backbone is the plumbing behind the military’s space-based internet. It functions as a low Earth orbit satellite constellation providing robust, high-capacity, and low-latency data transport for the Joint Force, connecting sensors and weapons systems continuously, globally, and securely. Think of it as a private, hardened version of Starlink built specifically for battlefield communications, one that soldiers, ships, and aircraft can rely on even in contested environments where ground-based networks have been disrupted.

SpaceX is quietly becoming the U.S. Military’s only reliable rocket

The Space Force was direct about why SpaceX was selected. “The SDN Backbone leverages the best of commercial innovation and delivers a strong foundation for the SDN mission set — a huge benefit and enabler for our warfighters,” said USSF Col. Ryan Frazier.

“We aren’t trading speed for scale; we are demanding both. By using rapid prototyping and Other Transaction Authorities, we are ensuring our advanced solutions are integrated and delivered to the warfighter as fast as possible,” added USSF Lt. Col. Fry, SDN Backbone system program manager.

The SDN Backbone will work alongside the Space Development Agency’s Transport Layer, with the two systems forming a unified open architecture to provide critical data transport for current and future Department of War missions.

As Teslarati has reported, this is not SpaceX’s first Space Force contract of 2026. In April, the Space Force awarded SpaceX $178.5 million to launch missile tracking satellites, and SpaceX is already embedded in the Golden Dome missile defense software group. The $2.29 billion SDN Backbone award puts SpaceX at the center of how the American military communicates in space, a position with direct implications for its reported $1.75 trillion IPO valuation as the company heads toward a public offering as early as June 2026.

Tesla’s dedicated factory for building up to ten million Optimus units is officially under construction at Gigafactory Texas.

Drone footage released on May 27 by Giga Texas observer Joe Tegtmeyer captures the significant milestone of the first steel structure officially standing at Tesla’s new Optimus factory on the North Campus of the facility.

Phase two of land reclamation is advancing steadily, and the progress will let the new building extend nearly the full length of the main Giga Texas factory, potentially exceeding 4,000 feet, while measuring somewhere between 50 and 70 meters narrower. Extensive foundation work is proceeding as well.

This facility forms a central element of Tesla’s broader North Campus expansion at Giga Texas. The project will add more than 5.2 million square feet of new industrial space. It sits alongside other advanced developments, including a Terafab for next-gen AI chips. The scale reflects Tesla’s commitment to transforming humanoid robotics into a core pillar of the company’s future.

Musk has said that Optimus will be the biggest product in the world on several occasions. He believes it will be Tesla’s biggest valuation contributor.

Tesla prepares to expand Giga Texas with new Optimus production plant

Tesla plans to build about 10 million robots at the site annually once it is completed, which would be about 27,000 units each day.

The Optimus plant at Giga Texas is part of Tesla’s phased strategy for Optimus manufacturing. In an effort to start production of the robot well before the Giga Texas plant is complete, Tesla ended production of the Model S and Model X vehicles, which were built in Fremont, California, to make way for initial Optimus manufacturing efforts.

Production there will start in either July or August of this year, and early units will support internal factory tasks while the team gathers real-world data to refine processes. The Gigafactory Texas facility will house a second-gen production line. It targets high-volume output starting in Summer 2027.

Musk has repeatedly described Optimus as potentially more valuable than Tesla’s entire vehicle business. Current versions are already completing minor tasks around various facilities, while Tesla continues to refine its abilities and add new features.

Tesla’s total investment could reach several billion dollars. Significant challenges lie ahead, including the creation of an entirely new manufacturing ecosystem, the refinement of AI systems for dependable autonomy, and the development of reliable supply chains for actuators, sensors, and other components.

Nevertheless, the visible progress at Giga Texas highlights Tesla’s capacity to translate ambitious concepts into physical reality.

Tesla’s Optimus factory stands as much more than a simple expansion project, as it is quite literally the second phase of what could potentially be the biggest product ever. With construction beginning, 2027 is poised to become a transformative year for Tesla, as it evolves even further from an electric vehicle leader into a pioneer of intelligent, general-purpose machines.
