SpaceX set to launch 240th Starlink satellite as space internet nears prime time
SpaceX is just hours away from a Monday launch that should leave the company with almost 250 Starlink satellites in orbit — the latest in several recent steps towards prime time for the fledgling space internet constellation.
Scheduled to lift off no earlier than (NET) 9:49 am EST (14:49 UTC) on January 27th, a twice-flown Falcon 9 booster, new upper stage, 60 Starlink satellites, and a mysteriously blank payload fairing will try to thread the needle from SpaceX’s Cape Canaveral Air Force Station (CCAFS) LC-40 pad. Weather is tepid according to USAF forecasts and Monday’s – already just 50% ‘go’ – doesn’t even account for extremely high-speed upper-level winds that will absolutely have to wane before Falcon 9 can launch.
SpaceX’s fourth dedicated launch, today’s mission – known as Starlink V1 L3 (the third launch of v1.0 satellites) – will raise the number of spacecraft the company has placed in orbit to 240. Based on past statements from executives and SpaceX’s very own Starlink.com website, successfully completing Starlink V1 L3 could place the company just a hop, skip, and a jump away from the space-based internet constellation’s prime-time. With a little luck, the fledgling satellite internet provider could be serving customers much sooner than almost anyone might imagine.
As of now, it appears that SpaceX will indeed attempt to launch later today despite a good chance that weather conditions will force the company to try again on January 28th. Thankfully, SpaceX’s unique operating procedures brings with it a fair amount of flexibility to scrub launches with very little consequence less than 40 minutes before liftoff.
SpaceX is able to wait that long out of sheer necessity. The company introduced the use of ‘subcooled’ liquid oxygen and kerosene on its Falcon launch vehicles all the way back in 2016, encouraged by the fact that its propellant becomes significantly denser as it gets colder. By toeing the line between liquid oxygen and kerosene actually solidifying into slush, SpaceX was able to boost Falcon 9’s payload capabilities by an incredible ~30% or more. To get that benefit, however, Falcon 9’s propellant must remain as cold as possible, and it begins warming the second that it leaves its far-more-insulated storage tanks and enters Falcon 9.
As a result, SpaceX must load Falcon 9 and Falcon Heavy with propellant as late as physically possible, translating to no sooner than 35 minutes before liftoff on all recent launches. In other words, if the weather is firmly on the ‘bad’ side of things at T-38:00-35:00, SpaceX is often able to scrub a given launch attempt before propellant loading begins, both saving the rocket from an unnecessary thermal cycle and saving propellant that might otherwise have to be wasted.
120 satellites, 20 days
Weather challenges and the likelihood of a 24-hour delay aside, SpaceX will soon launch its third batch of upgraded Starlink v1.0 satellites — also the company’s fourth dedicated launch of 60 spacecraft. If things go as planned, SpaceX will have launched nearly 250 satellites total – all but 5 (or so) of which are happily operating in Earth orbit right now.
Deemed Starlink V1 L3, a successful mission later today will also mean that SpaceX has launched an incredible 120 spacecraft – weighing more than 30 metric tons – in less than 20 days. It’s difficult to say for sure, but it’s very likely that that will mark the latest global record secured by SpaceX, following on the heels of the company’s recent ascendance as the newest owner of the world’s largest private satellite constellation (~180 satellites).
However, the ultimate goal of Starlink is, of course, to deliver unprecedentedly high-performance internet service to customers anywhere on Earth. The “anywhere on Earth” modifier is likely more than 20 dedicated SpaceX launches away from reality, but the company has said it will begin serving internet to customers in “the Northern U.S. and Canada in 2020”. As of mid-2019, SpaceX indicated that that regional North American beta test could begin after just six launches.
More recent comments from a SpaceX executive suggest that it could require more like 8 launches of 60 Starlink satellites before initial service can begin in North America, but that ultimately means that the company should be no less than 50-65% of the way there after Starlink V1 L3. With a little luck, that could mean that SpaceX is just two or three Starlink launches away from inviting the first non-employee customers onto the company’s space-based internet. Given SpaceX’s current launch cadence, six Starlink launches may well be well behind the company by the end of February – perhaps just a month or less from now.

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.
