NASA picks diverse astronaut roster for SpaceX Crew Dragon 2021 mission
With Demo-2, the final certification test flight of SpaceX’s Crew Dragon capsule nearing completion, NASA is looking ahead to future operational crewed missions. NASA previously announced that following NASA astronauts Bob Behnken and Doug Hurley’s successful return from the International Space Station (ISS) in early August, three NASA astronauts and one Japanese astronaut of the Japan Aerospace Exploration Agency (JAXA) would soon be following on their own flight to the Space Station, SpaceX’s first operational crewed flight known as “Crew-1.” This mission is tentatively scheduled to occur no earlier than Fall of 2020.
Just days ahead of Demo-2’s anticipated conclusion, NASA, along with its international partners, has announced the roster and date of SpaceX’s third operational crewed mission referred to as “Crew-2.” Like Crew-1, the Crew-2 mission will feature a diverse international roster of four astronauts. Onboard will be veteran flyers, NASA astronauts Megan McArthur and Shane Kimbrough, along with JAXA astronaut Akihiko Hoshide, and European Space Agency (ESA) astronaut Thomas Pesquet. Should everything go as planned with Crew-1, Crew Dragon’s third operational crewed flight, Crew-2, is scheduled for liftoff no earlier than the Spring of 2021.

NASA keeps it in the family
One Crew-2 participant stands out from the rest, NASA astronaut Megan McArthur. She is a veteran NASA flyer having previously flown aboard the STS-125 space shuttle Atlantis mission in May of 2009. Although Crew-2 will be her second time to orbit, it will be her first visit to the ISS. During her first mission, she spent her time in orbit serving as a Mission Specialist servicing NASA’s Hubble Space Telescope. In 2019 she was appointed as NASA’s Deputy Chief of the Astronaut Office ISS Operations Branch, a role in which she provides support to astronauts in training and aboard the ISS.
Not only is McArthur an experienced space flyer and well-versed in mission support, but she is also married to NASA astronaut Bob Behnken. While Behnken served as Joint Operations Commander for Crew Dragon’s Demo-2 mission, McArthur was back at SpaceX headquarters in Hawthorne, CA training for her own Crew Dragon mission to the ISS.

McArthur was joined by her NASA and international partners Crew-2 crewmates to train at the SpaceX facility utilizing the Crew Dragon simulator. According to an interview with ESA astronaut Thomas Pesquet, the entire crew has been at various training facilities located in Texas and California presumably for weeks familiarizing themselves with Crew Dragon and ISS specific training, just as Behnken and Hurley did prior to their Demo-2 departure.
Looks like I'll be the first European to ever ride a Dragon into space! Training has already started at SpaceX's futuristic facilities. Stay tuned for more updates… and wait, how do you install the "launch" app on these giant tablet-screens? 😅😉🙃 pic.twitter.com/wD7zOf7EAl

Commercial and international crew will bring the ISS to full capacity
NASA astronaut Shane Kimbrough will fly for his third trip to orbit after having previously flown aboard space shuttle Endeavour for STS-126 and aboard a Russian Soyuz spacecraft for Expedition 49/50 in 2016. Japanese astronaut Akihiko Hoshide will be the second JAXA astronaut to fly aboard SpaceX’s Crew Dragon following Soichi Noguchi on Crew-1. ESA astronaut Thomas Pesquet will be the first European to fly aboard the Crew Dragon. It will be his second mission to orbit following a six-month-long stay aboard the ISS in 2016.
The 2021 Crew-2 mission will increase the number of ISS occupants from six to a full complement of seven. Crew-2’s four Dragon Riders will be joined by a three-member crew set to launch aboard a Russian Soyuz spacecraft. The increase of long-duration crew members will allow NASA to “effectively double the amount of science that can be conducted in space,” as stated in an official NASA Commercial Crew blog post. The Crew-2 astronauts are expected to stay aboard the orbiting outpost for six months.

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
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 Assisted Driving expands to tenth EU country
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.
