SpaceX gets first taste of coronavirus epidemic's consequences

SpaceX’s next scheduled rocket launch has been indefinitely delayed after Argentina – responsible for the SAOCOM 1B satellite payload – put strict travel restrictions in place, the first sign of the coronavirus epidemic’s consequences for the company.

Previously expected to launch as early as March 30th, the ~3000-kg (6600 lb) SAOCOM 1B radar satellite departed its Bariloche production facilities and arrived at Cape Canaveral around February 23rd, around the same time pandemic impacts began to be felt outside of China. Now likely sitting in a SpaceX payload processing facility at Cape Canaveral Air Force Station (CCAFS), it appears that SAOCOM 1B will have to wait for the foreseeable future before teams from Argentina and other countries are able to access the spacecraft and prepare it for launch.

While the delay is unfortunate, it hardly comes as a surprise at the same time dozens of countries around the world are considering – or already enacting – extreme countermeasures to mitigate the damage that will be caused by the COVID-19 pandemic. Thankfully, once Argentinian space agency (CONAE) employees are able to prepare SAOCOM 1B for flight, the mission is still set to make history, marking the first time a rocket launches on a polar trajectory from the United States’ East Coast in more than a half-century. In the meantime, SpaceX – while not deriving any income – also has ways of potentially taking advantage of a bad situation and exploiting unexpected downtime as a result of customer delays.

In October 2018, SpaceX successfully launched SAOCOM 1B’s predecessor – SAOCOM 1A – from its Vandenberg Air Force Base (VAFB) facilities, using a West Coast landing pad (LZ-4) for the first time ever. The spacecraft has successfully operated in space ever since, serving scientists, farmers, and more with high-quality satellite radar and Earth observation data.

Planned as a two-satellite constellation, CONAE spent another 15 or so months manufacturing and assembling the sister spacecraft, reaching the integration completion milestone in December 2019. After completing a few additional mechanical and electrical tests to verify the satellite’s health in January and February 2020, SAOCOM 1B was loaded aboard a Russian Antonov cargo plane and flown directly to Florida’s Kennedy Space Center (KSC), landing at the same runway NASA’s Space Shuttle once used.

Shortly after the growing global pandemic began to bare its teeth, the Argentinian government made the decision to almost completely ban international travel for the time being, while citizens now face heightened restrictions in a bid to legally enforce social distancing precautions. A scientific satellite launch has unsurprisingly not won exemption rights, meaning that it’s now all but impossible for the Argentinian space agency to send people and supplies back and forth from Florida – a necessity for something as complex as a satellite launch campaign.

As such, SpaceX’s SAOCOM 1B launch will be delayed until Argentina is able to loosen domestic and international travel restrictions – the timeline for which is anyone’s guess.

Bittersweet lemonade

Prior to the commercial mission’s indefinite delay, SpaceX’s seventh dedicated Starlink and sixth v1.0 satellite launch – Starlink L7 or Starlink V1 L6 – was expected no earlier than (NET) April 2020, sometime shortly after SAOCOM 1B’s NET March 30th launch. However, CEO Elon Musk and a second executive recently revealed that SpaceX is building Starlink satellites faster than it can launch them – churning out as many as six spacecraft in a single day.

Previously proposed on Teslarati, SpaceX may thus have a substantial backlog – ranging from one to several launches worth – of satellites that are ready for flight and either waiting for transport or already in Florida. In 2020, SpaceX has completed four 60-satellite Starlink launches in ~11 weeks, averaging a bit less than three weeks per mission. Even if SpaceX’s Starlink factory only averages 4-5 satellites per day each month, that would mean that the company is still building at least 20-40 extra satellites for each batch of 60 it launches.

In other words, if a separate Falcon 9 booster, upper stage, and payload fairing are already prepared for launch or SAOCOM 1B customer CONAE is willing to let SpaceX use its rocket (much less likely), the company could feasibly replace the mission on its manifest with an internal Starlink launch. This would reduce the amount of time the company’s workforce is listless as a result of the pandemic – a move that wouldn’t save money, per se, but would more efficiently distribute resources that will otherwise be wasted. For now, though, we – and the rest of the world – will have to wait and see.

How SpaceX Is raising Raptor’s sea-level thrust while holding engine mass steady

Published

on

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:

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 Assisted Driving expands to tenth EU country

Published

on

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’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.

Tesla starts showing how FSD will change lives in Europe

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 expands Robotaxi geofence in Houston with an ode to SpaceX merger

Published

on

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.

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.
