SpaceX Falcon Heavy rocket kicks off fifth mission with most spectacular launch yet
SpaceX’s fifth Falcon Heavy lifted off shortly after sunset on the US Space Force’s USSF-67 mission, producing one of the massive commercial rocket’s most spectacular launches yet.
Powered by three Falcon 9-derived boosters, each with nine Merlin 1D engines, Falcon Heavy fired up and soared off of SpaceX’s Kennedy Space Center LC-39A pad at the start of its Sunday launch window. Producing up to 2326 tons (5.13 million lbf) of thrust shortly after liftoff, Falcon Heavy upheld its position as the world’s most powerful commercial rocket and the second most powerful operational rocket.
USSF-67 largely mirrored SpaceX’s November 1st, 2022 USSF-44 Falcon Heavy launch, and even used the same side boosters. Flying for the second time in 75 days, B1064 and B1065 aced their roles in the mission and separated from Falcon Heavy’s expendable center booster (or core) around three minutes after liftoff. The side boosters immediately flipped around with thrusters powered by compressed nitrogen gas and ignited three of their nine Merlin 1D engines to boost back to the Florida coast. After coasting back to Florida, they completed brief reentry burns to lessen atmospheric heating and fired up one last time to gently touch down at SpaceX’s LZ-1 and LZ-2 landing pads.

Another mysterious military mission
Because Falcon Heavy lifted off after sunset, local skies were dark and the rocket quickly climbed back into daylight, creating spectacular contrast between twilight and the bright rocket exhaust. When Falcon Heavy’s side boosters flipped around and reignited, their high-velocity exhaust plumes slammed into the center core’s opposing plume, producing spectacular interactions and a nebula-like cloud that caught even more of the daylight. Had Falcon Heavy lifted off just a handful of minutes later, a darker sky could have made for an even more incredible ‘nebula’ or ‘jellyfish’, but the rocket’s first twilight launch was still spectacular.
After both side boosters touched down, SpaceX ended its live coverage at the request of the Space Force, reiterating the mission’s secretive customer and nature. Compared to USSF-44, the USSF hasn’t confirmed much about the USSF-67 mission’s payloads, but Falcon Heavy is known to be carrying a geostationary communications relay satellite called CBAS-2 and likely built by Boeing.
CBAS-2 is joined by Northrop Grumman’s third Long Duration Propulsive EELV or LDPE-3A, a combination of a propulsive kick stage and a satellite. LDPE-3A is carrying a collection of rideshare satellites and payloads and is designed to operate for months in orbit. Using USSF-44 as a guide, the total USSF-67 payload could weigh roughly 3.75 to 4.75 tons (8,250-10,500 lb).
Climbing to GSO
While small compared to ordinary payloads, Falcon Heavy is launching USSF-67 directly to a geosynchronous orbit. Direct-to-GEO/GSO launches are exceptionally challenging for the rocket. Falcon Heavy must first sacrifice one of its three boosters just to ensure the Falcon upper stage is traveling fast enough and has enough propellant to spare when it separates. The upper stage must then conduct at least three or four burns.
The first burn likely carried the upper stage and USSF-67 payload into a parking orbit around 300 kilometers (~185 mi) above Earth’s surface. A second burn of the upper stage’s Merlin Vacuum engine will lift the pair into a geosynchronous transfer orbit (GTO) with the low end still around 300 kilometers but the high end around 35,800 kilometers (~22,250 mi). Finally, the upper stage must survive a roughly five-hour coast to that apogee. During that coast, the rocket must survive passes through both of Earth’s harsh radiation belts and maintain perfect control of its orientation and tank pressures to keep its refined kerosene fuel from freezing, its cryogenic liquid oxygen (LOx) from boiling away, and itself from bursting as its propellant warms and expands.
If it does all of those things right, the upper stage will be able to complete a circularization burn at apogee and deploy its CBAS-2 and LPDE-3A payloads directly into geosynchronous orbit (~35,786 x ~35,786 km). At GSO, satellites orbit at the same speed as Earth spins, allowing them to indefinitely hover over the same region of the planet, making it useful for Earth observation, surveillance, and communications. Finally, the Falcon upper stage will attempt to complete one last burn to send itself into a graveyard orbit just above GSO, where it will eventually run out of power and lose control.
It will take around 6-8 hours after liftoff before SpaceX or the USSF can confirm if the mission was a success. Rewatch SpaceX’s fifth Falcon Heavy launch and dual booster landing here.
SpaceX CEO Elon Musk recently confronted worries about orbital data centers and launching satellites in mass quantities in space, as some voiced concerns about crowding.
Musk’s SpaceX plans to combat the issue of needing data centers by launching them into space instead of taking up valuable real estate on Earth. It has been a major point of SpaceX’s future, including its looming IPO, which could be the largest ever.
In a recent interview filmed at SpaceX’s Starlink terminal factory in Bastrop, Texas, Elon Musk directly addressed concerns that deploying large numbers of AI satellites for orbital data centers could crowd Earth’s orbit. His message was straightforward and reassuring: space is vast beyond human intuition.
“Space is really big,” Musk said. “It’s not like space is gonna get crowded. Space is enormous. If you actually look at it relative to the Earth, the satellites are so tiny you can’t even see them.” He emphasized that even zooming in makes a satellite appear large, but from a planetary perspective, they are minuscule specks.

Musk pointed to SpaceX’s real-world experience operating roughly 10,000 Starlink satellites as evidence that large constellations can be managed safely. “We’ve got a pretty good idea of how to operate just really large constellations and do it safely,” he noted. SpaceX remains the only operator with meaningful experience at this scale, giving the company unique insight into tight orbital packing without compromising safety
The discussion highlighted SpaceX’s plans for “AI1” satellites—essentially orbiting racks of AI compute powered by massive solar arrays and cooled via radiative panels in space’s vacuum.
These satellites leverage proven Starlink V3 technology, making them simpler to design than communications satellites. A first-generation unit targets around 150 kW peak power, with a 70-meter wingspan for solar panels and radiators. Laser links will connect them to each other and the Starlink network, delivering low-latency access (on the order of a few milliseconds from low-Earth orbit).
FCC accepts SpaceX filing for 1 million orbital data center plan
Musk framed orbital data centers as a practical solution to Earth’s constraints on AI growth. Ground-based facilities face power shortages, water demands for cooling, and grid limitations. In space, constant sunlight (no day-night cycle), vacuum radiative cooling, and abundant solar energy offer clear advantages.
Production will ramp up at an expanded “Gigasat” factory in Bastrop, with solar manufacturing already underway and full AI satellite output expected at reasonable volume by the end of 2027. Starship’s rapid, high-volume launch capability, aiming for multiple flights per hour, will make massive deployment feasible.
Critics sometimes raise risks like space debris or Kessler syndrome, but Musk’s response underscores scale: even a million satellites would represent an imperceptible fraction of available orbital volume when viewed against Earth’s size. SpaceX’s automated collision avoidance and deorbiting designs for Starlink further mitigate concerns.
This vision ties into broader ambitions. Musk sees orbital AI compute as a step toward harnessing more of the Sun’s energy, advancing humanity on the Kardashev scale from a Type 0 civilization toward Type 1 and eventually Type 2. By moving power-hungry data centers off-planet, SpaceX aims to unlock orders-of-magnitude more compute while preserving Earth’s resources.
Musk’s comments should ease public anxiety. With proven operational expertise, incremental engineering, and the immensity of space itself, orbital data centers represent not overcrowding, but smart expansion into the final frontier.
Tesla Full Self-Driving (Supervised) is currently listed as a Level 2 suite in terms of its passenger cars. As its Robotaxi platform continues to move quickly, it has been recognized as a Level 4 ride-sharing program by the State of Texas, as Tesla recently self-certified itself.
However, a Wall Street analyst is arguing that Tesla (NASDAQ: TSLA) has effectively achieved Level 4 autonomy in most conditions in all of its vehicles, drawing on personal experience and data released by the company.
Alex Potter of Piper Sandler said in a note to investors on Wednesday that “Tesla has solved the self-driving puzzle,” pointing to decisions to offer insurance discounts for FSD-enabled policies as a signal of confidence, which is backed up by stellar safety records compared to human driving.
Investing.com initially reported on Potter’s new note.
Additionally, Potter looks at the recent start of Cybercab production at Giga Texas as a potential indication that Tesla is ready to offer some level of unsupervised driving at least in the near future. The Cybercab has no steering wheel or pedals, completely eliminating the ability for human input.
He also sees Tesla’s allocation of “several hundred million USD (if not $1B+)” as confidence internally, seeing as it would be tough to set aside that amount of capital toward a project that the company does not see as relatively near-term.
Forward thinking, especially as Cybercab has no human controls, it would make sense that Tesla is at least close to self-driving. How close is another question.
Tesla has routinely teased that unsupervised FSD is close, but there are still a lot of things it feels as if the company has to roll out some more capability, including unsupervised parking features, known as “Banish,” better operation with regional self-driving performance, and other improvements.
That is not to say that Tesla FSD is super impressive already. It has already completed coast-to-coast drives across the United States and Canada, it routinely takes the stress out of driving for most people, and it has proven through Tesla Safety Reports that it is safer and involved in accidents less frequently than humans.
🚨 These are the first-ever FSD safety statistics out of the Netherlands, showing it was over 3.5x safer than human driving on Dutch roads.
The most recent numbers out of Tesla for North America show:
-Over 5.5 million miles between accidents for Teslas using FSD
-660k miles… https://t.co/XKlRzgSGEh pic.twitter.com/HX6kzh0ZKc— TESLARATI (@Teslarati) June 9, 2026
Even Potter believes it is capable, as he used it to go from Missoula, Montana, to Minneapolis, Minnesota, back in April.
“There’s no substitute for personal experience,” he wrote.
Tesla has finally and officially confirmed that Actually Smart Summon, commonly known as ASS, will make its way to the Cybertruck two and a half years after first deliveries.
The feature, which is part of the Full Self-Driving suite, allows owners of any Tesla to literally summon their vehicle to their location in a parking lot. It is limited by range and speed, especially as there is nobody in the vehicle, but is a great feature to have for rainstorms, busy parking lots, or for injured passengers (I recently used it so I could give my Fiancèe a hand leaving a sports injury doctor after she pulled her calf).
Tesla Summon has been a lifesaver for picking up my Fiancèe as she pulled her calf during a 10-mile race in Philadelphia this past weekend!
It went from one of her least favorite features of the Tesla to one of the most useful:pic.twitter.com/CPs6lTSPA8

Summon has been available on every Tesla that is currently available, but the Cybertruck has not had the feature in the two and a half years that customers have been taking deliveries.
There were a few things that Tesla had to work out with Full Self-Driving features, Summon in particular, with the Cybertruck.
Initially, its Steer-by-Wire system handles low-speed maneuvers differently than a typical mechanical steering connection available in the S3XY lineup. This required some additional time of development to allow Tesla to retrain and validate the AI models specifically for the feature within Cybertruck.
Additionally, the overall size and weight of Cybertruck impacted expected dynamics, has an impact on braking distances, and even obstacle avoidance in tighter lots. Tesla prioritized safety over launching the feature ahead of having the utmost confidence in it.
However, the wait is finally over, at least it seems that way. Tesla said that Cybertruck will receive ASS through a Software Update “shortly,” but did not give an explicit date. Tesla has said that Summon is coming in the past, only for it to be delayed yet again.

We anticipate that Summon will roll out within the Cybertruck in less than a week, but there are still some reservations about that timing because, ultimately, nobody knows what Tesla will do outside of Tesla. The Spring Update for many came well late, at least a month past the initial rollout wave.
The rollout of Summon to Cybertruck is a great milestone for Tesla, even if it has come later than most would really like to admit. Now that Cybertrucks will be summoned across parking lots, it will be awesome to see reactions to the massive pickup with no driver sitting in the driver’s seat.
