SpaceX’s 13th Starlink launch has been indefinitely delayed by “severe weather in the recovery area, later explained by CEO Elon Musk as case of the drone ship losing its battle with the ocean.

Originally scheduled to launch as early as September 17th, Starlink-12 – the 12th Starlink v1.0 mission – was pushed to September 18th about an hour before liftoff. SpaceX didn’t offer a reason then but is now reporting that weather in the recovery zone (Atlantic Ocean) was to blame for the 24-hour recycle and the indefinite launch delay that followed soon after.

CEO Elon Musk went further, revealing that the SpaceX drone ship assigned to Starlink-12 was unable to hold its position in strong Atlantic Ocean currents, forcing the company to delay the mission indefinitely. Until conditions improve in SpaceX’s drone ship recovery zone, the company will likely be unable to launch Starlink missions. Musk, however, already has a solution in mind.

In the same tweet, Musk revealed that SpaceX means for its drone ship “thrusters to be upgraded for future missions,” an obviously intuitive response to drone ships being overpowered by ocean currents. There’s one simple problem, though: drone ship Just Read The Instructions, the same ship currently unable to hold its position in (admittedly strong) ocean currents, completed extensive upgrades just a handful of months ago.

Prior to those upgrades, JRTI and OCISLY were effectively identical – both sporting a few modest generators and four relatively small station-keeping thrusters (bright blue). After more than half a year of work, drone ship JRTI came out the other end with dramatically larger azimuth thruster pods and at least several times the power output. The space beyond drone ship JRTI’s booster landing deck has been more or less filled to the brim with new generators.

In other words, short of some major structural changes or a smaller landing area for Falcon boosters, it’s hard to imagine how SpaceX could substantially upgrade Just Read The Instructions’ already-upgraded generators and thrusters.

In drone ship JRTI’s defense, the Eastern seaboard is still feeling the remnants of Hurricane Sally at the same time as Hurricane Teddy is just a few days away. Just ~48 hours from now, Starlink-12’s Falcon 9 booster landing zone will be subject to 30-40 mph (50-70 km/h) winds and peak wave heights of 15 feet (~4.5m) in the shadow of Teddy. The seas in that region will likely remain untenable for booster landings until September 24th or 25th at the earliest without major changes in current forecasts.

Current climate models don’t necessarily predict an increase in the frequency of Atlantic Ocean hurricanes as a result of global warming, although warming will very likely boost the intensity of most hurricanes to a major degree. As such, it’s a bit of a wash whether investing heavily in dramatic drone ship performance upgrades would actually be worth it for Falcon booster recovery, given that the tropical storm season only lasts a fraction of the year. If SpaceX wants to consistently launch 50-100+ times per year out of Florida, it’s likely a no-brainer.

Regardless, if SpaceX does pursue upgrades far beyond Just Read The Instructions’ current setup, it will be fascinating to see what the company’s two workhorse drone ships end up looking like. If current forecasts hold, Starlink-12 is unlikely to launch until late next week, a delay that has pushed Starlink-13 (previously NET late September) into October.

SpaceX nails “Lucky 13” astronaut launch, leaning into Tesla tradition and superstition

SpaceX launched Crew-13 astronauts to the ISS Thursday, setting up a record fast Dragon docking.

SpaceX launched NASA’s Crew-13 mission to the International Space Station on Thursday morning, getting four astronauts to orbit despite a forecast of thunderstorms and gusty winds that had threatened to push the flight to Friday.

Falcon 9 lifted off from Space Launch Complex 40 at Cape Canaveral Space Force Station at 11:10 a.m. ET carrying Dragon Grace, NASA confirmed. On board are NASA commander Jessica Watkins, NASA pilot Luke Delaney, Canadian Space Agency astronaut Joshua Kutryk and Roscosmos cosmonaut Sergey Teteryatnikov. The first stage booster, B1101, landed at Landing Zone 40 beside the pad on its third flight after previously supporting Crew-12 and a Starlink mission.

It was the first spaceflight for Delaney, Kutryk and Teteryatnikov. Watkins, who flew on Crew-4 in 2022, became the first NASA astronaut to launch aboard a Crew Dragon twice.

Before launch, the crew rode to the pad in Teslas, a tradition on NASA’s SpaceX crew flights since 2020. This time the cars carried specialty plates reading “Lucky 13.” Watkins said the mission patch leans into the number on purpose, as a nod to Apollo 13 and the resilience of that crew.

Grace is now on a short trip to the station. Docking at the forward port of the Harmony module is scheduled for about 7 p.m. ET, roughly 7 hours and 50 minutes after liftoff, which Space.com notes would be the fastest Crew Dragon transit to the ISS yet. Most Dragon flights take around 15 to 24 hours to catch the station. Hatch opening is planned for 8:25 p.m. ET.

The launch came more than two weeks later than originally planned. An oxidizer leak was found in Grace’s propulsion system in August, and NASA and SpaceX added time for tests. That pushed back the return of Crew-12, which has been aboard the station since February and is now set to splash down off Southern California next week. Crew-13 is expected to stay about six months.

SpaceX already holds NASA orders for crew rotations through Crew-17, while Boeing is preparing an uncrewed Starliner flight to the station as early as December.

Crew-13 was only the first of three SpaceX launches planned for Thursday, as Teslarati previewed on Wednesday. A Falcon 9 launched its Transporter-18 mission from California today, where Google will be launching its first orbital artificial intelligence (AI) test satellite. Meanwhile, Falcon Heavy is set to launch the classified NROL-97 mission for the National Reconnaissance Office from Launch Complex 39A at 11:53 p.m. ET. Its two side boosters will return to Landing Zones 1 and 2, which means Central Florida could hear up to three sonic booms in a single day. The busy stretch follows Starship’s Flight 14 on Monday, which reached orbit for the first time.

Tesla moves forward on Wireless Charging for vehicles

Tesla has moved its Wireless Charging efforts for its electric vehicles forward, as it had a new patent published today, one that it submitted back in March.

The patent describes a system for detecting foreign objects on the wireless charging pad under varying temperatures, aiming to mitigate any undesired results that could come from something being on top of the charging pad.

The abstract of the patent states:

“The present disclosure relates to methods and systems that can reliably detect foreign objects on a wireless charging pad under varying temperatures. In some examples, an object detector can utilize a set of inductive coils included in resonant tanks, and excite the resonant tanks using signals in a range of frequencies including or near a nominal resonant frequency of the resonant tanks. The object detector can detect a metal object based on resistance of a coil increasing and inductance of the coil decreasing. By analyzing the shifts and/or distributions in resonant frequencies and output magnitudes (e.g., output voltage peaks), the object detector can distinguish between changes of frequencies and magnitudes caused by temperature and those caused by foreign objects to accurately detect the foreign objects.”

The object detection system will utilize a set of inductive coils included in resonant tanks, and “excite the resonant tank using signals in a range of frequencies including or near a nominal resonant frequency of the tanks.” Metal can be detected by an increase in the coil’s resistance and a decrease in the coil’s inductance.

By analyzing shifts or disruptions in resonant frequencies and output magnitudes, the system can detect foreign objects. These types of safeguards need to be implemented through the normal operation of the charging pads.

Tesla says its Cybercab wireless charging efficiency is ‘well above 90%’

Tesla plans to utilize wireless charging with Cybercab and Robotaxi-enabled units to help streamline the fully autonomous experience from A to Z. The last thing the company wants to do is have any sort of small obstruction preventing the rider from experiencing Robotaxi as intended.

Tesla launches improved Model 3 in China with V2L, new interior option

Published

Tesla has launched its newest iteration of the Model 3 in China with a slew of new features, including the highly requested V2L (vehicle-to-load) feature and a new interior option.

The Model 3 now has a 16″ front touchscreen with improved resolution, a black headliner, V2L capabilities, Zen Grey interior in the Premium and Performance trims, as the White option has officially been discontinued, and 19″ Dark Nova Wheels, which are standard on the Model 3 Premium only.

The touchscreen in the U.S. version of the Model 3 is just 15.4″, so the newly upgraded screen is .6″ larger. Additionally, the Black Headliner, now standard on Model Y vehicles in the U.S., is coming to China.

Additionally, Tesla’s decision to end the white interior option has also made its way to the Asian market, as Zen Grey is the lighter color consumers can now go with. It is slightly different from the previously offered White option:

These options are available in China, Australia, and New Zealand as well, as Giga Shanghai serves those markets, bringing its mass-market vehicles to those countries in the South Pacific.

The Model 3 trims are now priced at:

  • Rear-Wheel-Drive – 235,500 yuan (~$35,000)
  • Long Range Rear-Wheel-Drive – 259,500 yuan ($38,700)
  • Long Range All-Wheel-Drive – 285,500 yuan (~$42,600)
  • Performance – 339,500 yuan (~$50,600)

These features have yet to make their way to the U.S., which might upset some buyers, but it is probably a good sign that Tesla will bring these changes to U.S. trims sometime next year. Potentially, these could come even sooner, as they could be used to stimulate demand for the year-end sales push.

Nevertheless, when things start at Giga Shanghai, they usually end up in the U.S. market. Tesla has also already started to install things like the Black Headliner and larger touchscreen in certain U.S.-built vehicles, so these things will be easy to implement across other vehicles in the lineup.
