SpaceX launches two Falcon 9 rockets in seven hours

Published

on

Two SpaceX Falcon 9 rockets have successfully launched a Crew Dragon carrying four astronauts and a new batch of Starlink internet satellites a little over 7 hours apart, nearly halving the company’s previous record.

A Falcon 9 rocket on the East Coast kicked things off with a launch out of NASA’s Kennedy Space Center (KSC) LC-39A pad – leased by SpaceX since 2014 – at noon EDT (16:00 UTC). A rare new Falcon 9 booster lifted an expendable upper stage and flight-proven Crew Dragon capsule – carrying four professional astronauts – most of the way free from Earth’s atmosphere before heading back to Earth and landing without issue on a SpaceX drone ship. The upper stage continued to low Earth orbit and deployed Dragon, kicking off a 29-hour journey to the International Space Station (ISS).

Seven hours and ten minutes later, a second Falcon 9 rocket lifted off from SpaceX’s Vandenberg Space Force Base (VSFB) SLC-4E pad, bursting through a thick layer of coastal fog. Following a successful launch and landing of booster B1071 and two good burns of the rocket’s upper stage, Falcon 9 deployed another 52 Starlink V1.5 satellites, adding to the more than 3000 working satellites already in orbit.

And SpaceX isn’t done. As early as 7:07 pm EDT (23:07 UTC) on October 6th, less than 24 hours after Starlink 4-29, a third Falcon 9 rocket is scheduled to launch from SpaceX’s Cape Canaveral Space Force Station (CCSFS) LC-40 pad. Rounding out the trio, the mission will carry Intelsat’s Galaxy 33 and Galaxy 34 communications satellites into a geostationary transfer orbit (GTO).

The mission will be Falcon 9 booster B1060’s 14th launch, significantly raising the bar for the commercial acceptance of reused SpaceX rockets. Prior to Galaxy 33/34, SpaceX’s commercial reuse record was held by Transporter-3, which was Falcon 9 B1058’s tenth launch.

The completion of two Falcon 9 launches in a little over 7 hours nearly halves SpaceX’s previous record of 14 hours and 8 minutes, set by a pair of launches in June 2022. It also demonstrates that the company can repeatedly prepare for and complete multiple Falcon 9 launches in very close proximity – more or less a necessity if it wants to hit CEO Elon Musk’s unprecedented target of “up to 100 launches” in 2023.

It isn’t a record for all of spaceflight, however. That likely falls to the Soviet R-7 family of rockets, 2 of which launched just 25 minutes apart in 1969. However, 3 Falcon 9 launches in 31 hours (Crew-5, Starlink 4-29, and Galaxy 33/34) is likely a record for all rockets. Parsing astrophysicist Jonathan McDowell’s extensive records, the R-7 family likely held the record for decades after completing 3 launches in 40 hours in 1978.

But, as it turns out, SpaceX already beat that record when it launched 3 Falcon 9 rockets in 36 hours in June 2022. 3 Falcon 9 launches in 31 hours thus breaks SpaceX’s record and the world record. That’s become an increasingly common occurrence for a company that has beaten its competitors so thoroughly that, by many measures, it has become peerless. Now, only the records of the former Soviet Union and a retired NASA rocket can outmatch SpaceX, a single 20-year-old company.

In less than three years, SpaceX has launched 30 astronauts: more than twice as many as China but a tiny fraction of the 852 people NASA’s Space Shuttle launched over its 30-year career. SpaceX’s Falcon family of rockets is the most reliable in history after 154 consecutive successes in less than six years, and Falcon boosters have completed more successful landings (145) than Space Shuttle orbiters. But its Dragon spacecraft will likely never best the Soviet and Russian Soyuz capsule and its variants, and Falcon will almost certainly be retired before it can come close to the R-7 rocket family’s extraordinary record of 1844 launches over 65 years.

But in the modern era, SpaceX is simply unmatched.

Tesla has a Cybercab problem nobody saw coming

Tesla’s Cybercab line now builds robotaxis faster than Tesla can deploy them, Lars Moravy says.

Tesla’s Cybercab line in Texas can now build the two seat robotaxi faster than the company can put it into service, according to Lars Moravy, Tesla’s Vice President of Vehicle Engineering. “We don’t run every day because the line can run so fast. It’s currently outpacing our deployments,” Moravy said in a new Cybercab deep dive from Munro Live. “So, it’s a bit of a race right now. Who’s going to go faster? Right now the manufacturing line’s ahead.”

Tesla’s official Robotaxi account shared a Cybercab analysis video on X on Monday, calling it a “Cybercab engineering deep dive.” Moravy’s comments go further than what he told analysts on the Q3 earnings call last week, when he said the Cybercab line’s listed capacity of more than 125,000 units a year undersells what it can actually run.

The tour shows where that speed comes from. Tesla’s unboxed process splits the Cybercab into front, rear, side and center modules that are built and tested on their own before they meet on a short final line. That final line has just 25 fully automated stations, which Tesla’s team estimated is a fifth to a tenth of what a Model Y needs. The full line is about 78% automated, the framing line is already at 100%, and the layout uses roughly 50% less floor space per vehicle. The stated goal is “100% automation in 10 second cycle time,” or one finished Cybercab every 10 seconds.

Tesla also deleted the paint shop. Only the side modules are coated, and the exterior panels get their color inside the molding machine. Engineers said the car is designed to run at least 500,000 miles, which matters for a vehicle that will spend most of its day carrying riders.

The battery got the same treatment. The Cybercab uses an 88S6P pack of 4680 cells in a steel enclosure, a first for Tesla, with each module potted separately so a single failed module can be swapped instead of the whole pack. Wireless battery management boards replace a wiring harness, and new contactors are fast enough to drop the pyro fuse entirely. Tesla’s battery director graded the pack an A minus, compared with a D for the Model Y structural pack and a B minus for Cybertruck. Up front, the drive unit runs an 11:1 gear ratio versus roughly 9:1 on most Teslas, since the Cybercab does not need a high top speed.

The deployment side is now the bottleneck Moravy described. Tesla had more than 50 Cybercabs working the Formula 1 weekend in Austin, and Texas records show 463 Cybercabs registered. Tesla said on its earnings call that Cybercab service will launch in Dallas next month, and Moravy said the company is aiming to get Cybercabs to customers by the end of 2026. Every unit built so far has gone into Tesla’s own fleet since the line moved into volume production in April.

Munro Live also asked when it could get a Cybercab to tear down. Tesla’s answer: “Not yet.”

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

Published

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.
