SpaceX has successfully launched and landed Falcon 9 once again, sending a massive communications satellite on its way to an operational orbit and recovering booster B1056 aboard drone ship Of Course I Still Love You (OCISLY).

As we speak, Falcon 9’s two payload fairing halves are – if everything went as planned – slowly coasting through the edge of Earth’s atmosphere beneath GPS-guided parafoils, a nearly 40-minute journey from the time they separate from Falcon 9 to the moment they are scheduled to touch down. Stationed hundreds of miles downrange in the Atlantic Ocean, twin recovery ships Ms. Tree and Ms. Chief await with their huge nets taut, ready for the first attempted catch of two fairing halves.

Meanwhile, Falcon 9’s upper stage completed its initial orbital insertion burn, carrying the multi-ton Kacific-1/JCSAT-18 communications satellite to a low Earth parking orbit around 300 km (185 mi). After a 20-minute coast, the upper stage reignited its lone Merlin Vacuum (MVac) engine and burned for more than 50 seconds, raising one end of the spacecraft’s orbit as high as possible in what is known as a geostationary transfer orbit (GTO) insertion.

At least from past performance, Falcon 9 is unable to launch a ~6800 kg (15,000 lb) satellite to a full GTO while still leaving enough propellant for booster recovery, which SpaceX clearly chose to do on this launch. This means that Kacific-1/JCSAT-18 will likely fall several thousand (to ten thousand or more) kilometers/miles short of a full geostationary transfer orbit, where one end of the orbit has actually been boosted to geostationary orbit (36,000 km, 22,000 mi). Using propellant carried aboard the satellite itself, it will make up the difference, raising itself to a full GTO and ultimately circularizing into geostationary orbit, where the Kacific-1/JCSAT-18 can begin serving customers around the world.

Land Falcon 9 booster B1056 certainly did, coming to an eventful stop aboard drone ship OCISLY around nine minutes after lifting off from the coast of Florida. With respect to that liftoff, Teslarati photographer Richard Angle had several remote cameras onsite, so stay tuned for that article in the coming days.

Finally, 33 minutes after launch, Falcon 9’s upper stage – having successfully delivered Kacific-1/JCSAT-18 to what was described as a nominal orbit – deployed the bus-sized spacecraft, officially completing SpaceX’s 13th and likely second-to-last launch of 2019. If all goes well, SpaceX has one final launch scheduled in 2019 – the company’s third 60-satellite Starlink mission.

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 rescue mission for stranded ISS astronauts nears end — Here’s when they’ll return home

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

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.
