The day before SpaceX aced its eighth Starlink launch in three months, President and COO Gwynne Shotwell implied that the company’s constellation of satellites could achieve “full [global] connectivity” just a handful of months from now.

Speaking at Satellite 2021’s “LEO Digital Forum” on April 6th, Shotwell revealed that SpaceX hopes to cross that milestone a few months after a total of 28 operational Starlink launches have been completed. Around 25 hours after her panel appearance, SpaceX launched its 490th Starlink satellite of the year, more or less wrapping up the first quarter of 2021.

SpaceX’s April 7th Starlink launch and booster landing was the 23rd successful launch of operational ‘v1.0’ satellites since they began flying in November 2019. All told, of the 1383 operational satellites launched by SpaceX in those 17 months, some 1369 are still in orbit, at least 1356 are functioning as expected, and more than 900 have reached their final orbits and are operational. Another 400 appear to be in long-term parking orbits dozens to hundreds of kilometers below their operational 550 km (~340 mi) ceiling, the purpose of which is unclear.

Once the 400-500 satellites now in low parking orbits reach whatever orbital parameters they’re waiting on, it’s unlikely to take more than two or three months for them to boost up to an operational altitude. Starlink-23 added another 60 around 250 km (155 mi). All told just the satellites SpaceX has in parking orbits are several times larger than the next largest constellations.

Given Shotwell’s 28-launch comment and a general idea of SpaceX’s 2021 launch cadence targets, it’s possible to extrapolate to a reasonably accurate timeline for the constellation to reach a point of “full connectivity globally” – albeit with a few caveats. First, it’s unclear what exactly the SpaceX President and COO meant with that phrase, given that SpaceX will require a substantial number of polar orbit satellites before Starlink can truly cover every single inch of Earth’s surface.

If Shotwell is including one or more dedicated polar Starlink launches in her rough 28-launch estimate, Starlink’s global connectivity timeline is effectively a complete mystery until SpaceX offers more information on its plans to build out that segment of its constellation. If she isn’t accounting for total polar coverage and means something akin to “full connectivity” for ~99% of the global population, though, it’s a simple task to estimate when Starlink might reach that milestone.

While SpaceX appears to be standing down Starlink launches for around two weeks to focus fully on Crew Dragon’s second operational astronaut launch (Crew-2), the company is expected to jump right back to rapid-fire Starlink launches in the last week or so of April. If, from that point on, SpaceX matches its Q1 2021 average and manages one Starlink mission every ~12 days, Starlink-28 could launch in late-June – and possibly even earlier. From then on, it’s just a matter of verifying each satellite’s health in space before allowing the spacecraft to boost up to their operational orbits.

In other words, barring unprecedented numbers of early satellite failures or unusually long orbit-raising periods, it’s likely that SpaceX will have enough operational satellites – around 1700 – for near-total, uninterrupted Starlink coverage of the inhabited world by the end of Q3 (September) 2021.

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

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.
