SpaceX Falcon Heavy rocket celebrates 4th launch debut anniversary
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.

Nvidia CEO Jensen Huang explains difference between Tesla FSD and Alpamayo
“Tesla’s FSD stack is completely world-class,” the Nvidia CEO said.
NVIDIA CEO Jensen Huang has offered high praise for Tesla’s Full Self-Driving (FSD) system during a Q&A at CES 2026, calling it “world-class” and “state-of-the-art” in design, training, and performance.
More importantly, he also shared some insights about the key differences between FSD and Nvidia’s recently announced Alpamayo system.
Jensen Huang’s praise for Tesla FSD
Nvidia made headlines at CES following its announcement of Alpamayo, which uses artificial intelligence to accelerate the development of autonomous driving solutions. Due to its focus on AI, many started speculating that Alpamayo would be a direct rival to FSD. This was somewhat addressed by Elon Musk, who predicted that “they will find that it’s easy to get to 99% and then super hard to solve the long tail of the distribution.”
During his Q&A, Nvidia CEO Jensen Huang was asked about the difference between FSD and Alpamayo. His response was extensive:
“Tesla’s FSD stack is completely world-class. They’ve been working on it for quite some time. It’s world-class not only in the number of miles it’s accumulated, but in the way it’s designed, the way they do training, data collection, curation, synthetic data generation, and all of their simulation technologies.
“Of course, the latest generation is end-to-end Full Self-Driving—meaning it’s one large model trained end to end. And so… Elon’s AD system is, in every way, 100% state-of-the-art. I’m really quite impressed by the technology. I have it, and I drive it in our house, and it works incredibly well,” the Nvidia CEO said.
Nvidia’s platform approach vs Tesla’s integration
Huang also stated that Nvidia’s Alpamayo system was built around a fundamentally different philosophy from Tesla’s. Rather than developing self-driving cars itself, Nvidia supplies the full autonomous technology stack for other companies to use.
“Nvidia doesn’t build self-driving cars. We build the full stack so others can,” Huang said, explaining that Nvidia provides separate systems for training, simulation, and in-vehicle computing, all supported by shared software.
He added that customers can adopt as much or as little of the platform as they need, noting that Nvidia works across the industry, including with Tesla on training systems and companies like Waymo, XPeng, and Nuro on vehicle computing.
“So our system is really quite pervasive because we’re a technology platform provider. That’s the primary difference. There’s no question in our mind that, of the billion cars on the road today, in another 10 years’ time, hundreds of millions of them will have great autonomous capability. This is likely one of the largest, fastest-growing technology industries over the next decade.”
He also emphasized Nvidia’s open approach, saying the company open-sources its models and helps partners train their own systems. “We’re not a self-driving car company. We’re enabling the autonomous industry,” Huang said.
