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.
A Tesla Semi was involved in a fatal collision on U.S. Highway 50 in Dayton, Nevada, on Sunday, June 28, 2026, marking the first known fatal crash involving the electric Class 8 truck. The incident occurred around 7:20 a.m. at the intersection with Traditions Parkway, approximately 40 miles east of Reno and close to Tesla’s Gigafactory Nevada.
According to the Lyon County Sheriff’s Office and the Nevada State Police Highway Patrol, a semi-truck struck two passenger vehicles stopped at a traffic signal. The truck hit the vehicles from behind. Two people were pronounced dead at the scene, and a third person suffered life-threatening injuries and was flown to a hospital, Forbes reported.
Preliminary statements gathered at the scene by the Lyon County Sheriff’s Office suggested the truck driver may have fallen asleep at the wheel. However, the Nevada Highway Patrol, which is leading the investigation, stated that the official cause has not yet been determined.
Additional information is expected to be released early the following week. The truck was seized for evidence as part of the ongoing probe.
Responders at the scene included deputies from the Lyon County Sheriff’s Office, personnel from the Nevada Highway Patrol, Central Lyon County Fire Department, and the Nevada Department of Transportation. The crash led to the temporary closure of U.S. 50 in both directions.
The Tesla Semi is Tesla’s battery-electric heavy-duty truck, produced at the nearby Gigafactory in Nevada. Authorities initially described the vehicle as a semi-truck; its make was subsequently confirmed through reporting and scene identification; an interesting bit of information here, as the Semi is not yet available publicly and many do not know that Tesla builds electric trucks.
The investigation remains active, with no further official details on contributing factors or vehicle systems released as of early July 2026.
This incident highlights ongoing scrutiny of commercial vehicle safety on Nevada highways, particularly involving fatigue. Law enforcement continues to gather evidence and witness statements.
Tesla has expanded its Robotaxi program to Miami, Florida, marking the third state the autonomous ride-hailing platform has made its way to since launching last Summer.
Tesla announced today that the Robotaxi suite would now officially launch rides in a geofence in Miami:

The first geofence in Miami covers approximately 10 to 14 square miles. The area appears to be focused on western and central Miami, including Miami International Airport (MIA). It also includes popular routes like SR 826 (Palmetto Expressway), US 41 (Tamiami Trail), and connectors such as SR 968, 953, 959, and 972.
This is Tesla’s initial Miami launch zone, smaller and more targeted than some competitors’ areas (for example, Waymo’s initial rollout was broader in eastern neighborhoods). It prioritizes high-traffic, airport-linked routes before wider expansion.
The expansion is a huge signal for Tesla that it is now operating in Florida, a heavy-traffic state with many tourist areas, including Fort Lauderdale, Palm Beach, and the Boynton area, all of which are coastal and will attract perhaps millions of tourists in any given year.

The Tesla Robotaxi network launched last year on June 22, in Austin, Texas, beginning limited commercial operations in that city. It expanded shortly thereafter into the San Francisco Bay Area of California in late July 2025, marking entry into a second state with service covering key areas such as San Francisco, San Jose, and Berkeley.
Full commercial service was achieved in Austin by November 18, 2025, strengthening its presence within Texas before further growth.
In 2026, the network continued expanding across Texas with the addition of Dallas and Houston on April 18, significantly broadening its footprint in the state. This new launch into Miami marks Tesla entering a new state and bringing active locations to include Austin, Dallas, Houston, San Antonio in Texas, and the Bay Area in California.
These sequential expansions have steadily increased the network’s reach across major metropolitan areas in Texas, California, and Florida, focusing on scaling operations city by city and state by state since the initial Austin debut.
Tesla CEO Elon Musk has tempered expectations for the company’s humanoid robot Optimus, emphasizing that initial production will ramp up slowly despite recent progress on the manufacturing line. In a July 1 reply on X, Musk responded to optimistic community speculation by stating, “No, Optimus production will be extremely slow at first, as everything is new. This is not like making a car.”

The comment came in response to a post theorizing that Tesla had accelerated Optimus V3 development and might soon unveil an impressive demonstration with multiple units already in meaningful production. Musk’s clarification highlights the fundamental differences between scaling a novel humanoid robot and Tesla’s established automotive operations, which benefit from over a century of refined supply chains, tooling, and processes.
Recent updates show tangible advancement. Musk shared a photo of himself walking the Optimus production line at Fremont, where Tesla is converting former Model S/X manufacturing space. According to Q1 2026 earnings commentary, limited production is slated to begin in late July or August 2026 on this converted line.
Tesla Optimus project fires up as Musk sees production line progress
Musk previously noted that Optimus features roughly 10,000 unique parts, making early output rates “literally impossible to predict” and describing them as “quite slow.” A larger dedicated factory at Giga Texas is under construction, targeting higher-volume production around summer 2027 with long-term annual capacity potentially reaching millions of units.
Some experts point out that pioneering humanoid robotics demands inventing new automation techniques, actuator supply chains, and quality-control standards in real time. Unlike vehicles, where components and assembly methods are mature, every element of Optimus—from dexterous hands to AI-integrated movement—requires fresh engineering solutions. Early units are expected to handle simple factory tasks before expanding to more complex roles.
This cautious approach aligns with Tesla’s history of under-promising and over-delivering on complex technologies. While enthusiasts hoped for rapid deployment, Musk’s message underscores a deliberate strategy: prioritize reliability and iterative improvement over rushed volume.
Analysts suggest the S-curve ramp typical of new manufacturing will eventually accelerate once foundational issues are resolved, positioning Optimus as a potential trillion-dollar product line.
Musk has long envisioned Optimus transforming labor markets, assisting in homes, factories, and hazardous environments. By setting realistic timelines, Tesla aims to build sustainable momentum rather than risk disappointment. As the Fremont line comes online this summer, investors and fans will watch closely for the first production metrics and capability demonstrations.
