SpaceX Falcon 9’s next major US Air Force launch slips into early 2020 ahead of busy Q4
According to an August 20th update from the US Air Force’s Space and Missile Systems Center (SMC), SpaceX’s next dedicated USAF launch – the third completed GPS III spacecraft – has slipped one month and is now scheduled no earlier than (NET) January 2020.
Known as GPS III Space Vehicle 03 (SV03), SpaceX’s next US military launch will follow just a few months after United Launch Alliance (ULA) is set to launch GPS III SV02, scheduled to lift off at 9am EDT, August 22nd. SpaceX kicked off the lengthy GPS III launch campaign in December 2018, successfully placing the ~3900 kg (8600 lb) communications and geolocation spacecraft into a transfer orbit. The mission also marked SpaceX’s first intentionally expendable Falcon 9 Block 5 launch, a trend that may or may not continue with the company’s next GPS launch.
Known as GPS Block IIIA, SV01-03 are the first three of a batch of 10 spacecraft total, produced by Lockheed Martin for an anticipated cost of roughly $600M apiece. The US Government Accountability Office (GAO) expects [PDF] little to no cost savings per unit for Block IIIA’s follow-up, Block IIIF, in which 22 additional GPS III spacecraft will be built to fully upgrade the military’s GPS constellation. GAO estimates that those 22 satellites – likely to also be built by Lockheed Martin – will cost an incredible $12B, or ~$550M apiece.
On the scale of the US military’s woefully inefficient space procurement apparatus, ~$600M per satellite is sadly a pretty good deal. Two equally modern USAF satellite acquisition programs – the Advanced Extremely High Frequency (AEHF) and Space-Based Infrared System constellations – have both surpassed their initial cost estimates by more than a factor of two. Over the entire program, GAO estimates that six AEHF satellites no less than $3 billion each, while SBIRS is in even worse shape with six new satellites expected to cost $3.2 billion apiece.
Meanwhile, the Raytheon-built ‘OCX’ ground systems needed to take advantage of the ~$19B GPS III satellite upgrades has been just as much of an acquisition boondoggle, nearly doubling in cost over the last few years, bringing its final cost to no less than $6.2B after years of delays. All told, completing the upgraded GPS III constellation can be expected to cost a bare minimum of $25B. This cost doesn’t even include launches, but the cost of launching all the spacecraft is – in a rare instance – going to be a small fraction of the overall acquisition, perhaps $3-4B for all 32 satellites.
Regardless of the nightmarish costs and general inefficiency, Lockheed Martin and the USAF continue to slowly march towards initial GPS III operability. August 22nd’s ULA launch and January 2020’s SpaceX launch will take significant steps towards that capability, and will – with any luck – be followed by an additional two Falcon 9 GPS III launches in 2020. Six of ten IIIA satellites have already had launch contracts awarded, five of six of which were awarded to SpaceX.
End-of-year fireworks
GPS III SV03’s slip from December 2019 to January 2020 comes as plans for an ambitious final quarter have begun to take shape for SpaceX. Oddly, SpaceX is currently going through more than two months of downtime between its most recent launch (AMOS-17, August 6th) and its next mission (Starlink 1, NET late October). This will be the longest SpaceX has gone without launching since a catastrophic Falcon 9 failure grounded the company’s launch operations from September 2016 to January 2017.
By all appearances, customers’ payloads just aren’t ready, while SpaceX’s own Starlink constellation team is hard at work updating the satellite design and preparing for two back-to-back launches as early as October and November, potentially placing 120 high-performance satellites in orbit.
Aside from two Starlink launches scheduled in late-October and November, SpaceX has at least six other missions that could potentially launch in Q4 2019.
| Launch | Date (No Earlier Than) |
| Starlink 1 | October 17th |
| Starlink 2 | November 4th |
| Crew Dragon – In-Flight Abort | November 11th |
| ANASIS-II – South Korea | November – TBD |
| JCSat-18/Kacific-1 | November – TBD |
| Cargo Dragon CRS-19 | December 4th |
| Sirius XM-7 (SXM-7) | Q4 2019 – TBD |
| Crew Dragon – Demo-2 | December – TBD |
A lack of updates from Sirius XM and the fact that Crew Dragon’s Demo-2 launch will rely entirely upon the successful completion of its prior In-Flight Abort (IFA) mean that both will very likely slip into 2020. The remaining six launches, however, have a very decent chance of launching in 2019, assuming everything goes perfectly during satellite, Falcon 9, and launch pad pre-flight preparations.
SpaceX has successfully completed six launches in three months several times before, so six launches in Q4 2019 is entirely achievable, even if a pragmatist would do well to expect additional delays into 2020.

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.
