SpaceX wins NASA approval to launch astronauts on reused rockets and spacecraft

SpaceX appears to have won NASA’s approval to launch astronauts on reused Falcon 9 rockets and Crew Dragon spacecraft a matter of days after the company’s astronaut launch debut went off without a hitch.

Ever since SpaceX began landing and reusing orbital-class Falcon 9 boosters some 15 months after it won a NASA contract to develop Crew Dragon, the obvious possibility that the two groundbreaking technologies might one day meet has always floated just under the surface. Almost without fail, most joint NASA/SpaceX press conferences will receive a question or two about whether either party is thinking about or working towards astronaut launches on flight-proven spacecraft. Encouraged by the fact that partner Boeing’s separate Starliner spacecraft was sold to NASA with reusability in mind from the start, those questions continued up until (and after) the day SpaceX became the first private company in history to launch astronauts into orbit.

In a wholly unexpected turn of events, a modification to SpaceX’s ~$3.1 billion NASA Commercial Crew Program (CCP) contract was spotted on June 3rd. Without leaving much room for interpretation, the contract tweak states that SpaceX is now “[allowed to reuse] the Falcon 9 launch vehicle and Crew Dragon spacecraft beginning with” its second operational astronaut launch, known as Post Certification Mission-2 (PCM-2) or Crew-2. Given the spectacular, hiccup-free success of SpaceX’s inaugural astronaut launch and International Space Station (ISS) arrival just 3-4 days prior, it’s safe to say that NASA is extremely happy with the results of the mission.

Without a shred of doubt, SpaceX has worked tirelessly for years to earn enough of NASA’s technical trust to permit crewed launches on flight-proven hardware, a possibility that even the optimists in the crowd assumed was distant at best. It has almost always been an uphill battle for SpaceX – a fact made especially clear when framed beside partner Boeing. An inherently conservative organization, NASA has repeatedly given Boeing and its more traditional Starliner spacecraft and development approach the benefit of the doubt while frequently tearing into the nooks and crannies of SpaceX and Crew Dragon over half a decade of cooperation.

While functioning more like an anchor when SpaceX finds itself working with conservative, stubborn organizations like NASA and US military branches, the company’s wholly non-traditional style of development has secured technical success after technical success. Over the course of the second half of SpaceX’s 20-mission NASA Commercial Resupply Services 1 (CRS1) contract, the company has still managed to successfully launch dozens of tons of cargo to the space station with flight-proven spacecraft and boosters. From CRS-11 to CRS-20, five missions featured reused Falcon 9 boosters and all but one of those 10 flights featured once or even twice-flown Cargo Dragon spacecraft.

In short, SpaceX has demonstrated more than a dozen times to NASA that it’s fully capable of building, launching, and reusing orbital-class rockets and spacecraft. Additionally, before an unrelated design flaw destroyed the spacecraft during post-recovery testing, SpaceX successfully launched, recovered, and refurbished Crew Dragon capsule C201 in March 2019, demonstrating its dramatically improved reusability. While suborbital, Crew Dragon C205’s January 2020 In-Flight Abort (IFA) test also likely helped demonstrate the new spacecraft’s reusability and gave NASA more experience with the reuse of Falcon 9 Block 5 rockets as B1046’s fourth launch.

Every step along the way, SpaceX has put its money where its mouth is and proven that it’s more than capable of doing what much larger, more traditional companies have only claimed to be capable of – and often months or even years before its competitors and for hundreds of millions to billions of dollars less. While it’s much more likely that NASA has yet to actually certify SpaceX’s Crew Dragon spacecraft and Falcon 9 boosters for flight-proven astronaut launches, the June 3rd contract modification – at a minimum – signifies the space agency’s expeditious intent to do so. What is unambiguous is the schedule it lays out: SpaceX could potentially launch astronauts on a flight-proven rocket and spacecraft as early as its second operational taxi mission to the ISS.

Known as PCM-2 or Crew-2, the mission is scheduled to follow Crew Dragon’s first operational astronaut launch – Crew-1 – by roughly six months. Contingent upon Crew Dragon Demo-2’s safe return of NASA astronauts Bob Behnken and Doug Hurley later this year, Crew-1 is tentatively scheduled to launch on August 30th, although it could potentially launch even sooner. If successful, Crew-2 should follow as soon as mid-2021 and could potentially reuse Crew-1’s Falcon 9 booster and the Demo-2 or Crew-1 Dragon capsule.

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.
