SpaceX to launch secret “Zuma” payload same day as Tesla Semi event
SpaceX has completed preparations and is ready to launch the highly secretive “Zuma” satellite(s) at 5pm/8pm PST/EST on Thursday, November 16th, the same day Tesla will be holding its semi-truck unveiling event.
Updated: SpaceX has rescheduled the Zuma mission.

The Zuma launch campaign has been veiled in an extraordinary level of secrecy for SpaceX and the US launch industry in general, and this has piqued the interest of many.
In the last decade or two, the United States military apparatus has launched many dozens of satellites, and secrecy on the order of Zuma is unusual to say the least. Missions for the National Reconnaissance Office (NRO) typically feature some level of media presence and have developed a community of fans in the age of social media, taking advantage of cartoonish mission logos that can often be entertaining, if not vaguely disturbing.

However, no federal agency has yet to announce involvement in Zuma. The full extent of public information available can be found in a handful of tweets, with drastically less official info available from a leaky source on Reddit. Thus far, Northrop Grumman is known to have at least procured Zuma’s launch from SpaceX, and the same statement indirectly suggested that Zuma was in fact a government-related mission. NRO is the obvious option, with the Air Force or another branch of the US military or intelligence apparatus also a distinct possibility. It is entirely possible that the nature and parent of the mission will remain secret for the indefinite future, even after its launch.
Nevertheless, a handful of details allow us to speculate in greater detail. In May 2017, SpaceX launched NROL-76, a Department of Defense satellite that was intriguingly observed to have made very close passes to the International Space Station, far too close to have been a coincidence. Based on Notices to Airmen (NOTAMs) filed with the FAA and discussed earlier this week, it appears Zuma may be placed in an orbit very similar to that of NROL-76, suggesting that Zuma could be an iteration on NROL-76’s supposed orbit-to-orbit data gathering capabilities. This time, however, agency involvement has been completely shadowed. A blank fairing, sans any NROL-reminiscent logo, will be the tell-tale sign come tomorrow, when Teslarati’s launch photographer Tom Cross arrives at Kennedy Space Center for camera setup.

Meanwhile, as has become shockingly routine, SpaceX’s Falcon 9 first stage, core 1043, will conduct a Return to Launch Site (RTLS), landing at LZ-1 just a few miles from its launch pad. Like NROL-76, we can expect live coverage of the second stage and payload to end immediately after stage separation; bittersweet but esoteric fans, but likely to result in a unique focus on the stage returning to Earth.
On the horizon
Possibly more exciting than the launch itself, Zuma is expected to be the last launch from SpaceX’s Kennedy Space Center LC-39A facilities until Falcon Heavy, currently aiming for an inaugural flight around December 29th. After a solid year of repairs and refurbishment, SpaceX’s LC-40 launch pad is anticipating a return to flight operations with the CRS-13 Cargo Dragon mission on December 4th. Located within the Cape Canaveral Air Force Station just a few miles south of LC-39A, LC-40 suffered widespread damage after a Falcon 9 catastrophically failed while preparing for a static fire test on the pad.
Despite the tragic loss of vehicle and the Amos-6 payload, SpaceX has maintained a strong relationship with the owner, Spacecom, and was recently chosen for both a contractual reflight in 2019 and an additional launch in 2020.
SpaceX has also made great strides since returning to flight after Amos-6 in January 2017, and has enjoyed a truly groundbreaking year of incredible progress towards the goal of rapid reusability. Quite fittingly, LC-40 is expected to return to action while hosting yet another commercial reuse of a Falcon 9 first stage, this time with the hugely significant approval of NASA. The space agency has yet to make this decision resoundingly public, but respected industry insider NASASpaceflight.com has stated that it is all but in stone at this point in time. In a sense, the disaster that severely damaged LC-40 acted as a since-heeded wake-up call for SpaceX, and the venerable pad will rise from those ashes into a new era of reusable rocketry, led wholeheartedly by SpaceX.

SpaceX’s Raptor engine family has steadily increased sea-level thrust while simultaneously reducing mass, turning iterative engineering gains into substantially higher performance for the Super Heavy booster. CEO Elon Musk shed more light on how powerful Raptor 4 will be, and it’s pretty crazy.
Raptor 1 delivered 185 metric tons of thrust at roughly 2,080 kilograms, while Raptor 2 raised that to 230 tons while cutting mass to about 1,630 kilograms. SpaceX data for Raptor 3 lists a target of 280 tons at 1,525 kilograms (with further reductions in associated vehicle hardware), while operational flight ratings have been cited near 250 tons.
This morning, Elon Musk stated that Raptor 4 is expected to reach 300 tons of sea-level thrust at roughly the same mass as Raptor 3. Across these versions, thrust has risen by more than 60 percent from the first engines while engine mass has fallen, producing a sharp improvement in thrust-to-weight ratio. This is a true testament to how great SpaceX engineering has been:
🚀 Elon says Raptor 4 will make 300 tons of thrust at sea level at roughly the same mass as Raptor 3.
How far Raptor has come:
Raptor 1: 185 tf, 2,080 kg
Raptor 2: 230 tf, 1,630 kg
Raptor 3: 250 tf, 1,525 kg
Raptor 4: 300 tf33 on Super Heavy = ~9,900 tf, nearly 3x Saturn V https://t.co/HQDswZhyvL

With 33 engines on SuperHeavy, the jump from earlier versions to a 300-ton Raptor 4 would produce roughly 9,900 metric tons of total liftoff thrust, nearly three times the Saturn V’s approximately 3,400 metric tons from its five F-1 engines.
This is not just a larger number on a data sheet, either, as sea-level thrust is the force available the moment the vehicle leaves the pad. This is when it is heaviest and still deep in Earth’s gravity well and dense atmosphere.
Higher levels of sea-level thrust directly improves the initial thrust-to-weight ratio of the full stack. A higher ratio produces faster acceleration off the pad, which shortens the time the rocket has to spend fighting gravity, and gravity losses during the first minute or two of the flight are a major drain on total available delta-v. Every second shaved off of that early climb preserves more propellant energy for reaching orbital velocity or for carrying extra payload.
Because Super Heavy’s engine count is constrained by vehicle diameter and packing density, increasing thrust per engine is the most straightforward way to raise total liftoff performance without redesigning the booster structure or design.
The same-mass target for Raptor 4 is equally important. Holding engine mass roughly constant while raising thrust improves the engine’s own thrust-to-weight ratio and reduces the structural and propellant mass fraction that must be carried solely to support the engines.
Earlier Raptor iterations also simplified or eliminated extensive vehicle-side hardware such as heat shields. These gains compound: more force for less installed mass leaves additional capacity for propellant, payload, or operational margins such as engine-out capability.
For Starship’s architecture, the practical effects are large. Greater liftoff thrust supports heavier vehicles, larger propellant loads, and higher payloads to low Earth orbit, figures SpaceX has targeted in the 100-plus-ton reusable range. That capacity underpins orbital refueling, lunar missions, and eventual Mars cargo and crew flights.
Continued growth in sea-level thrust therefore tightens the gap between theoretical rocket performance and the high flight rates and reusability needed to make large-scale space transport practical.
Tesla has expanded its Tesla Assisted Driving (TAD) suite to its tenth European country, as Latvia joined a growing list of European Union member states authorizing the company’s advanced driver assistance technology.
Tesla Europe announced this morning that the system is now approved in Latvia, with a software rollout to begin soon.
The approval and rollout follow recognition of a provisional European type approval originally granted by the Netherlands’ RDW authority on April 10.
🚨 Latvia has just received approval for Tesla Full Self-Driving (Supervised)
This is the 10th country in the EU to gain approval:
1. Netherlands — 10 April 2026 (original RDW approval)
2. Lithuania — 20 May 2026
3. Estonia — 29 May 2026
4. Denmark — 9 June 2026
5. Belgium — 10 June 2026
6. Slovenia — 7 September 2026
7. Czechia — 21 September 2026
8. Croatia — 29 September 2026
9. Slovakia — 16 October 2026— TESLARATI (@Teslarati) October 26, 2026
Latvia’s Road Traffic Safety Directorate (CSDD) evaluated the Dutch documentation, coordinated with the other national authorities, and reviewed updates from Tesla. These included tightened limits on speed offsets, automatic resets of any manual speed adjustments after each trip, and stronger driver monitoring.
In Europe, the feature is marketed as Tesla Assisted Driving after a recent rule change that labeled the name “Full Self-Driving” as misleading.
The system remains an SAE Level 2 driver assistance tool, not unsupervised autonomy. It can control speed, steering, braking, lane changes, and intersections while following a navigation route. Drivers need not keep their hands on the wheel at all times, yet they must continuously monitor the road and be prepared to intervene immediately.
The sequence of EU recognitions began with the Netherlands in April and continued through Lithuania, Estonia, Denmark, Belgium, Slovenia, Czechia, Croatia, and Slovakia. Most have relied on mutual recognition of the single Dutch provisional approval rather than independent national testing.
These national clearances do not yet constitute bloc-wide authorization. An EU-wide decision requires a qualified majority in the Technical Committee on Motor Vehicles: at least 15 of 27 member states representing 65 percent of the EU population. Larger markets, like Germany, France, and Italy, remain under review, and a vote is expected this December.
However, for Latvian Tesla owners with compatible vehicles and software, the imminent rollout expands access to the supervised system while underscoring that attentive human oversight remains essential.
Tesla expanded its Robotaxi geofence in Houston, Texas, today, enlarging the service area and drawing a new rocket-shaped boundary across the city’s northwestern and central parts.
Although CEO Elon Musk said it was just a coincidence, the expansion seems to be an ode to SpaceX and its potential merger with Tesla.

It looks a lot like a rocket — we all remember the shape in Austin 🤣 https://t.co/cFOPEuiJ4u

The official Tesla Robotaxi account announced the change with the lines “Houston, we have liftoff” and “Bigger service area now live,” pairing them with a map overlay.
The prior white geofence, roughly 25 square miles covering Jersey Village, Harvest Bend, and the Willowbrook corridor along U.S. 290 and State Highway 249, now sits inside a larger blue zone that stretches southeast toward Bellair and closer to central Houston.
Houston’s Robotaxi service launched on April 18, 2026, the same day as Dallas, as Tesla’s first unsupervised public expansion beyond Austin. From the start, the vehicles were Model Ys running without anyone in the front seats, booked through the dedicated Tesla Robotaxi app and open to the public inside the geofence.
Trackers measured the initial zone at about 25 square miles; by late September it had not grown substantially. Community and registry data indicated a modest local fleet of unsupervised Model Ys, while dozens to nearly 200 Cybercabs, the purpose-built, steering-wheel-free two-seaters, have been spotted staging and testing in Houston lots, though public Cybercab rides remain limited to Austin for now.
Across the broader Robotaxi program, Tesla began public Robotaxi rides in Austin in June 2025, as a small geofence and vehicles with safety monitors became available for a ride-hailing service. Later on, Tesla removed the monitors and steadily expanded the service area until it covered most of the Austin metro area.
Unsupervised Robotaxi services now run in six cities: Austin, Dallas, Houston, Miami, Orlando, and Tampa. Cumulative driverless miles reported by the company have reached several million. The Cybercab entered public service in Austin in early September 2026 and has scaled rapidly there. The company has also said that Dallas is next for Cybercab rides in November, with further cities and 24/7 hours targeted by year-end, plus fleet-operator sales of the vehicle.
Waymo also operates a fully driverless service in Houston, which has been open to the public since August of this year.
The Houston expansion continues Tesla’s pattern of starting with tightly controlled validation zones before widening coverage as real-world data accumulates, while the rocket motif on the map underscores the company’s habit of injecting visual flair into its autonomy rollout.
Riders inside the new boundary can request unsupervised Model Y trips in the Robotaxi app; exact operating hours and further Cybercab availability remain subject to app updates and company statements.
