Filings and an official statement confirm that SpaceX could eventually build a Starlink internet constellation with tens of thousands of satellites, several times more than the company’s already ambitious plans.

“As demand escalates for fast, reliable internet around the world, especially for those where connectivity is non-existent, too expensive or unreliable, SpaceX is taking steps to responsibly scale Starlink’s total network capacity and data density to meet the growth in users’ anticipated needs.”  

SpaceX – October 15th, 2019

Uncovered through regulatory filings published on the International Telecommunications Union’s (ITU) eSubmission portal, the FCC filed documents hinting at plans for tens of thousands of new communications satellites. It was eventually confirmed by the ITU and eventually the company itself that SpaceX was behind the new filings, altogether accounting for up to 30,000 additional Starlink satellites.

Prior to this new filing, the ceiling for SpaceX’s Starlink satellite internet constellation was set around 11,900 spacecraft – 4400 in several low Earth orbits (LEO) and another 7500 in very low orbit (VLEO). Put simply, even the most ardent supporters and potential benefactors of such a colossal satellite constellation have never taken those particular numbers all that seriously – 12,000 satellites is nearly six times as many operational spacecraft currently in orbit.

To build even a fraction as many satellites would take resources on the order of a small country without a revolution in satellite manufacturing and mass production. Assuming a cost as low as $5 million per satellite (more or less unprecedented), launching just the first 4400-satellite segment would cost SpaceX a minimum of $22 billion, while the full 11,900 would be more like $60 billion.

And yet, as improbable as it sounds next to today’s satellite production status quo, CEO Elon Musk indicated that SpaceX’s very first 60 Starlink prototypes – launch in May 2019 – cost less than the launch itself. This implies that the cost of each of those beta spacecraft was probably $1 million at most and likely closer to $500,000 apiece. Around that price point, launching thousands of relatively high-performance satellites becomes far more reasonable, even if the figures are still substantial.

4400 satellites would become ~$2 billion, while ~12,000 satellites would become $6 billion. Combined with SpaceX’s new ITU filings, the current maximum of ~42,000 satellites might cost something like $20 billion – a huge price tag, no doubt, but far from impossible. Important to note is that SpaceX almost certainly plans to begin drawing significant income from its Starlink constellation after as few as several hundred satellites have been launched. SpaceX has already raised more than $1 billion to get Starlink close to that point.

Also critical is the fact that building hundreds (let alone thousands) of satellites annually will allow SpaceX to tap into economies of scale quite literally unprecedented in the history of satellite manufacturing, meaning that it’s hard to accurately judge how low the per-satellite cost might eventually fall. Regardless, at the moment, SpaceX’s filings for an additional 30,000 possible satellites are undoubtedly more of an act of “just in case” than a sign of firm plans.

In the present, SpaceX has plans for as many as four additional Starlink v1.0 launches between now and the end of 2019, although it looks likely that that may shrink to 1-2 missions. The next Starlink mission (deemed Starlink 1) is expected no earlier than late-October or November.

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.
