SpaceX set for back-to-back weekend launches: Crew Dragon abort test, 60 more Starlink satellites
Two SpaceX Falcon 9 rockets are currently on track to launch back-to-back missions just a handful of days from now, potentially supporting Crew Dragon’s second flight test ever and yet another Starlink satellite launch a little over two days from now.
Known as Crew Dragon’s In-Flight Abort (IFA) test, the first mission is scheduled to lift off from Kennedy Space Center Launch Complex 39A (KSC LC-39A) no earlier than (NET) 8 am EST (13:00 UTC), January 18th and will almost certainly produce some spectacular fireworks (even more so than usual). During the test, SpaceX’s newest flightworthy Crew Dragon spacecraft will attempt to escape from a supersonic Falcon 9 rocket, exceptionally challenging conditions that will almost certainly result in the immediate (intentional) destruction of Falcon 9’s upper stage and booster.
A few miles to the north, SpaceX is preparing an entirely different Falcon 9 rocket for the third launch of 60 upgraded Starlink v1.0 satellites in barely two months, scheduled to lift off NET 12:20 pm EST (17:20 UTC), January 20th from Cape Canaveral Air Force Station (CCAFS) Launch Complex 40 (LC-40). While the duo of launches will break no records for SpaceX, they will certainly set the tone the company is aiming to keep throughout the rest of 2020.
On January 11th, SpaceX successfully fired up Falcon 9 B1046 at Pad 39A, performing the booster’s fifth routine static fire test (if not more) in approximately two years. The first Block 5 booster built and flown by SpaceX, B1046 has performed three orbital-class launches since it debuted in May 2018 and even became the first Falcon 9 booster to launch three times in December 2018.
Since that milestone, B1046 spent several months at SpaceX’s Hawthorne, CA factory undergoing inspections and refurbishment. At some point, SpaceX assigned the thrice-flown booster to support Crew Dragon’s In-Flight Abort (IFA) test – effectively a death sentence – and shipped the booster to Florida, where it publicly appeared for the first time in months on October 3rd, 2019. Given that four more Falcon 9 boosters have now successfully performed three (or even four) orbital-class launches each, B1046’s now-imminent demise is certainly disappointing but remains extremely pragmatic.
Sure, B1046 could have theoretically flown several more orbital-class launches before it might have otherwise been quietly retired, but it is still the first Falcon 9 Block 5 booster qualified for flight. Although SpaceX and CEO Elon Musk were explicit that Block 5 would be the last major design iteration for the Falcon family of launch vehicles, that definitely doesn’t rule out tweaks – minor to major – that have likely been implemented since the rocket’s flight debut. In the 20 months since that debut, Falcon 9 and Heavy Block 5 boosters have performed more than two dozen launches and landings and checked off several reusability milestones.
In simple terms, those dozens of flights and reuses all translate to lots and lots (and lots) of high-fidelity data. That data – and often the hardware it’s connected to – can be used to extensively cross-check and improve the Falcon 9 and Heavy engineering models SpaceX created while designing, producing, and ground testing the Block 5 upgrade prior to its flight debut. It can also be used to upgrade to the rocket where needed, especially useful when it comes to reusability.
Although Falcon Block 5 boosters already appear to be exceptionally reliable and reusable, having checked off multiple third-flight and fourth-flight milestones in the last year, there is always room for improvement – especially if Musk is still serious about his long-held goal of launching the same Falcon 9 booster twice in ~24 hours. Along those lines, it’s safe to assume that at least some of the boosters that come off the assembly line after B1046 feature design tweaks meant to optimize for reliability and reusability, among other things.
For the most part, it seems that SpaceX is no longer aggressively pursuing ~24-hour booster turnaround, although they very likely intend to continue cutting the work hours required for (and thus the cost of) each reuse. B1046’s demise may shrink SpaceX’s reusable rocket fleet by one but the company will continue to debut the occasional new booster throughout 2020, ultimately ensuring that the fleet grows over time. Ultimately, if SpaceX only needs to spend a week or two inspecting and refurbishing each Block 5 booster and has a fleet of 10-20 or more, 24-hour turnaround may not even be necessary to achieve the desired results it was meant to represent.
Finally, SpaceX aims to launch its fourth batch of 60 Starlink satellites overall as few as ~52 hours after Falcon 9’s Crew Dragon In-Flight Abort mission and nextspaceflight.com reports that Falcon 9 B1051 will support the Starlink V1 L3 mission – the booster’s third orbital-class launch in ~10 months. Thankfully, B1051 – formerly tasked with supporting Crew Dragon’s Demo-1 orbital launch debut in March 2019 and Canada’s Radarsat Constellation Mission (RCM) in June 2019 – will almost certainly be attempting its second drone ship landing and third recovery overall.

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.
