SpaceX's next rocket launch on track to break a 20-month-old booster reusability record
Scheduled as early as next week, SpaceX’s next rocket launch could see the company break a 20-month-old record that is closely intertwined with the reusability of its Falcon 9 and Falcon Heavy boosters.
Unsurprisingly, that record – if broken – will tag along on one of up to two dozen Starlink satellite launches SpaceX has planned for 2020. The fourth launch of upgraded Starlink v1.0 satellites and fifth dedicated launch overall, SpaceX’s next Starlink mission – deemed Starlink V1 L4 – is currently set to lift off no earlier than (NET) 10:46 am EST (15:46 UTC) on February 15th. As usual, the mission’s Falcon 9 booster will attempt to land aboard drone ship Of Course I Still Love You (OCISLY), while SpaceX recovery ships Ms. Tree and Ms. Chief may attempt to catch both Falcon payload fairing halves for the third time ever.
According to Next Spaceflight, SpaceX has assigned thrice-flown Falcon 9 booster B1056 to the Starlink launch, potentially making it the fourth SpaceX rocket to complete four separate launches. However, while SpaceX’s fourth fourth-flight milestone is significant, B1056 is – barring delays – also set to break a record that could be even more important for rocket reusability.
SpaceX’s 10th finished Falcon 9 Block 5 booster, B1056 completed a flawless launch and landing debut on May 4th, 2019, sending Cargo Dragon on its way to orbit for CRS-17, the spacecraft’s 17th International Space Station (ISS) resupply mission. Instead of a more normal return-to-launch-site (RTLS) recovery at SpaceX’s Cape Canaveral-based Landing Zone, SpaceX opted to land the booster on drone ship OCISLY.
It’s believed that SpaceX and NASA made that decision out of an abundance of caution after an attempted LZ recovery following the Falcon 9 B1050’s CRS-16 Cargo Dragon launch saw the booster lose control and crash-land in the Atlantic Ocean less than a mile off the coast.
Regardless, SpaceX’s subsequent CRS-17 Cargo Dragon launch went exactly as planned and Falcon 9 B1056 landed smoothly aboard drone ship OCISLY. Less than two days after returning to Port Canaveral, B1056 even became the first SpaceX booster to have its landing legs retracted – a small but significant step along the path to true airplane-like reusability. 82 days later, B1056 successfully completed its second launch, sending another Cargo Dragon its CRS-18 resupply mission before landing at LZ-1. The booster completed its third mission a bit less than five months later, placing the 6800 kg (15,000 lb) Kacific-1 communications satellite into geostationary transfer orbit (GTO) on December 16th, 2019.
Now, SpaceX wants to launch B1056 for the fourth time as early as February 15th. Close observers will note that that would imply just 61 days between B1056’s Kacific-1 and Starlink V1 L4 launches, a feat that would make it SpaceX’s fastest ‘booster turnaround’ ever. Currently, that record stands at 71 days and was actually achieved just a month after SpaceX debuted Falcon 9’s reusability-focused Block 5 upgrade. However, that record turnaround was actually achieved by the B1045, SpaceX’s last Falcon 9 Block 4 booster.
Surprisingly, the closest SpaceX’s upgraded Block 5 rockets have gotten to beating B1045’s 71-day record was when the company turned around Falcon Heavy side boosters B1052 and B1053 in just 74 days before completing the giant rocket’s third orbital launch since February 2018. Now, barring calamities worthy of a ten-day delay, it looks likely that Falcon 9 booster B1056 will beat out the current record-holder by up to ten days (~15%).
According to a SpaceX engineer’s January 2020 presentation, SpaceX is currently capable of landing, refurbishing, and relaunching Falcon 9 and Falcon Heavy boosters in about a month (~30 days). With Falcon 9 B1056’s Starlink V1 L4 launch, SpaceX will hopefully be taking its biggest step in 20 months towards the goal of reusing Falcon boosters in a matter of days.

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.
