If everything goes as planned, SpaceX’s next 60-satellite Starlink launch will soon push the Falcon rocket family to the halfway point of its ambitious reusability design goals.

SpaceX has scheduled its sixth launch of 60 Starlink satellites no earlier than (NET) 9:42 am EDT (13:42 UTC) March 14th. Known as Starlink L6 or Starlink V1 L5 (referring to the fifth batch of upgraded v1.0 satellites), the Starlink mission will be the SpaceX’s fourth this year – a cadence that would enable up to 21 Starlink launches in 2020 alone. In other words, a successful launch this weekend would put SpaceX firmly on track to realize the repeated guidance that it would attempt 20-24 Starlink missions this year.

Given that SpaceX’s annual record stands at 21 launches and that the company has many additional non-Starlink launches planned for 2020, it’s always been clear that rocket reusability would be essential to even begin to approach the launch rates Starlink demands. Doing so without severely impacting customer missions – almost certainly an unacceptable tradeoff for SpaceX – is even more of a challenge. Thankfully, with its very next launch, SpaceX is about to push the rocket reusability envelope yet again, hopefully proving that the Falcon family is halfway to realizing its design goals.

SpaceX’s final iteration of the Falcon launch vehicle – known as its Block 5 upgrade – flew for the first time in May 2018 and has performed another 27 missions in 22 months since. When it debuted, SpaceX CEO Elon Musk spoke in depth about the Block 5 upgrade and the significant changes it introduced, stating that it primarily focused on improving reliability and reusability. Notably, every single Falcon 9 Block 5 rocket produced from then on would be virtually identical to the select few boosters destined to launch astronauts, meaning that all future SpaceX launches would directly benefit from the changes NASA required.

However, arguably the biggest public focus of Block 5 upgrade would be the upgrades it brought for SpaceX’s reusable rocketry program, with Musk describing it as a cumulative product of half a decade spent attempting to land rocket boosters. The big claim: Falcon Block 5 boosters would theoretically be capable of at least ten launches apiece with minimal to no repairs in between. After reaching 10-launch milestones, Musk further noted that boosters could potentially use periodical overhauls – much like modern aircraft – to achieve 100 or more launches apiece before retirement.

Eleven months after SpaceX launched and landed the same rocket for the third time, Falcon 9 booster B1048 became the first to complete four launches and landings, placing the first 60 Starlink v1.0 satellites in orbit in November 2019. Less than two months later, Falcon 9 B1049 matched its predecessor’s record, becoming the second booster to launch four times.

Now, according to Next Spaceflight, pathfinder Falcon 9 booster B1048 is scheduled to launch for the fifth time in support of Starlink L6 – a bit less than four months after it became the first SpaceX rocket to cross the fourth-flight milestone. Just days ago, SpaceX President and COO Gwynne Shotwell revealed that Falcon boosters might never need to fly more than ten times. Given that Falcon 9 Block 5 boosters were first and foremost designed to launch no less than ten times each, B1048 is now on the brink of reaching the halfway point of one SpaceX’s most ambitious Block 5 design goals.

If B1048 (and B1049 shortly after that) can prove that Falcon boosters can successfully launch five times, it’s hard to imagine any technical showstoppers that could prevent SpaceX from achieving its self-imposed ten-flight milestone. With SpaceX likely to attempt anywhere from 10-20 more Starlink launches this year, there will be no shortage of opportunities for Falcon 9 to continue pushing the envelope of reusability.

Tune in around 15 minutes before liftoff to catch SpaceX’s Starlink L6 launch live this Saturday, pending a successful Falcon 9 static fire test later today.

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.
