SpaceX sets Dragon reuse record, debuts drone ship on first launch in two months
Update #2: After a 24-hour weather delay, conditions were far more favorable on August 29th, allowing a SpaceX Falcon 9 rocket to lift off for the first time in almost two months and send a cargo-filled Dragon spacecraft on its way to the International Space Station (ISS).
Aside from marking the end of SpaceX’s longest launch hiatus in two years, CRS-23’s successful liftoff also means that the company has smashed the world record for fastest orbital space capsule reuse. As part of Cargo Dragon 2’s first reuse ever, SpaceX launched Dragon C208 just seven and a half months (227d) after its first orbital reentry and splashdown, handily beating the previous record of 328 days. Additionally, flying for the fourth time, Falcon 9 booster B1064 became the first rocket to land on brand new SpaceX drone ship A Shortfall of Gravitas (ASOG) after sending Dragon C208 on its way to the ISS.

Update: Although the weather forecast has worsened, SpaceX remains on track to attempt its first launch in eight weeks – a mission that will also smash one of the company’s orbital spacecraft reusability records.
While mostly mundane, a system preceding Tropical Storm Ida is producing conditions less than optimal for rocket launches, raising the risk of in-flight lightning strikes and the chances of Falcon 9 and Dragon flying through clouds containing precipitation (rain/ice/etc). Ultimately, that means that there’s just a 40% chance (down from 50% in the last few days) that weather conditions will be favorable for SpaceX to launch CRS-23. Regardless, barring a surprise announcement in the next few hours, it appears that there’s enough of a chance that SpaceX and NASA will still make an attempt.
If all goes according to plan, a flight-proven Falcon 9 rocket will send an upgraded Cargo Dragon on the way to orbit for the second time in seven months – almost twice as fast a turnaround as SpaceX’s ~340-day record for orbital spacecraft reuse. Tune in below around 3:20am EDT (07:20 UTC) to catch the hopeful launch live.
For the first time in more than nine weeks, SpaceX has completed a routine Falcon 9 preflight test known as a static fire and verified that the rocket is ready to launch later this week.
Save for at least one booster qualification test completed at SpaceX’s McGregor, Texas development facilities, Falcon 9’s August 25th static fire is the first since June 22nd. The upgraded Cargo Dragon space station resupply mission the rocket will support will also be SpaceX’s first launch since June 30th – the company’s longest hiatus between launches since a three-month pause that began two years ago.
Now, just a few days before that drought is expected to end, a SpaceX executive has partially explained why the company hasn’t launched a single Falcon rocket in ~60 days after completing a record 20 orbital launches in the first half of 2021.
Speaking at the 2021 Space Symposium on August 24th, SpaceX President and COO Gwynne Shotwell revealed that the company had chosen to pause Starlink missions (representing the vast majority of its 2021 launches) and focus on preparing a new generation of satellites for flight. Believed to be called Starlink V1.5, those new satellites represent a relatively small design change save for one crucial addition: multiple lasers.
All the way back in mid-2018, SpaceX launched its very first pair of Starlink prototype satellites – spacecraft that largely functioned as expected and provided a wealth of data but were almost nothing like the Starlink V0.9 and V1.0 spacecraft SpaceX would eventually start launching in 2019. Nevertheless, they did carry sets of small lasers generally known as optical intersatellite links or OISLs for short. Not radically dissimilar to the hundreds of thousands of miles of fiber optic cables that make up the backbone of the internet, lasers operating in the vacuum of space can effectively mirror the extraordinary bandwidth and performance offered by fiber connections – but wirelessly.
Instead of carefully insulated cables filled with tiny threads of glass, which really just serve as a controlled environment for light-based communications, OISLs enable a similar feat by replacing cables with extraordinarily precise mechanisms capable of aiming lasers with sub-millimeter precision from dozens or hundreds of miles away. As a result, laser interlinks are fairly complex and expensive devices – not something currently economical to install on thousands of satellites mainly focused on affordability.
SpaceX, of course, has wanted to install unprecedentedly affordable laser interlinks on thousands of Starlink satellites for as long as the constellation has been publicly discussed. If realized, it would create an extraordinary orbital mesh network that would allow Starlink to self-route a large portion of user communications without the need for a colossal network of tens of thousands of ground stations covering every inch of Earth – land, sea, ice, and all. A Starlink constellation with near-universal laser interlinks could also potentially allow the constellation to not only match – but beat by a large margin – the latency of best-case terrestrial fiber-optic connections.
After effectively completing Starlink’s first ‘shell’ of satellites earlier this year, SpaceX shifted its focus to preparing for polar Starlink launches from both its west and east coast facilities. While the first shell lacked interlinks entirely, SpaceX appears to have decided that all polar Starlink satellites will be launched with its own custom-built space lasers, even if that means delaying Starlink launches until those lasers are ready for action. Due to the fact that the vast majority of SpaceX’s launches as of late have been its own Starlink missions, the company’s Falcon rockets simply haven’t had anything to launch.
That should change on August 28th, when a thrice-flown Falcon 9 booster launches a refurbished spacecraft on its second orbital space station resupply – a first for SpaceX’s upgraded Cargo Dragon 2 vehicle. A Shortfall of Gravitas (ASOG), SpaceX’s newest drone ship, will also be supporting its first Falcon landing ever as part of CRS-23, hopefully recovering Falcon 9 booster B1064 for a fifth launch later this year.
Tune in around 3:20am (07:20 UTC) on Saturday, August 28th to watch SpaceX’s first launch in two months live.
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.
🚨 Tesla has just expanded its Robotaxi geofence in Houston
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.
