SpaceX sends OneWeb satellites to orbit on 55th launch of 2022

Published

on

SpaceX has successfully launched the first of at least three missions for Starlink competitor OneWeb, completing its 55th launch of the year in the process.

Hopefully ending a strange series of delays that began last month, Falcon 9 lifted off from SpaceX’s NASA Kennedy Space Center LC-39A pad several days behind schedule on December 8th, 2022. The rocket performed perfectly, ascending for about nine minutes to reach a parking orbit around 400 kilometers (~300 mi) above Earth’s surface. B1069, Falcon 9’s flight-proven booster, shut down, separated from the upper stage, flipped around with cold-gas thrusters, and began boosting back to the Florida coast two and a half minutes after liftoff.

Thanks to the launch’s timing, which happened moments after sunset, B1069 first experienced sunset on the ground, ascended back into the light after liftoff, and finally experienced a second sunset while racing back to Earth – all beautifully captured by SpaceX tracking cameras. Eight minutes after liftoff, the Falcon 9 booster touched down on SpaceX’s LZ-1 landing pad, completing its fourth orbital-class launch in 12 months. Around the same time, Falcon 9’s upper stage reached orbit.

An hour after liftoff, the upper stage ignited a second time to circularize its parking orbit. Its payload – a record 40 OneWeb satellites weighing roughly 6.5 metric tons (~14,300 lb) – was then deployed in two sets of 13 and one set of 14 over the next half hour, after which the upper stage likely performed a deorbit burn to ensure it doesn’t become space debris.

For its own Starlink internet constellation, SpaceX routinely launches 54+ satellites – weighing almost 17 tons (~37,000 lb) – at once, demonstrating the kind of efficiency that can be achieved when a satellite is explicitly designed to use as much of Falcon 9’s performance as possible. To some extent, OneWeb did something similar, but for a different rocket. OneWeb’s far more traditional 150-kilogram (~330 lb) satellites were loosely designed to launch on Russia’s Soyuz 2.1 after the company purchased up to 21 of the rockets for $1-1.5 billion in 2015.

But their more traditional hollow-box design and traditional cylindrical payload dispenser means they take up as much or more space than Starlink satellites despite weighing 50-100% less. OneWeb says each satellite provides up to 7 gigabits per second (Gbps) of bandwidth, while each Starlink V1 satellite appears to have about 20 Gbps.

As previously discussed on Teslarati, OneWeb directly competes with SpaceX’s far larger Starlink internet constellation, and refused to engage with the company for launch services – even though Falcon 9 could have likely deployed its satellites more quickly and efficiently – until it was forced to.

“The only reason OneWeb agreed to launch a small subset of its first-generation satellites on SpaceX rockets was a series of egregious actions from Russia that made the pair’s exclusive arrangement too toxic to continue. In June 2015, just 16 months after Russia illegally invaded Ukraine’s Crimea and Donbas regions, OneWeb chose to tie itself at the hip to the unstable aggressor with a firm $1-1.5 billion contract that committed the entirety of its first satellite constellation to 21 Russian Soyuz rockets.

OneWeb nearly escaped consequences from that dubious decision. But in February 2022, Russia doubled down on eight years of small-scale war and Ukrainian occupation with a full-scale, gloves-off invasion with explicit genocidal intent. Europe eventually responded in part with economic sanctions and military supplies that Russia did not appreciate. In response, Russia took a batch of 36 OneWeb satellites hostage, stole the Soyuz rocket OneWeb had already paid for, and killed any possibility of the company completing the six or seven Soyuz launches left under its Arianespace contract. In September 2022, OneWeb announced that it had written off a loss of $229 million as a result of those stolen satellites and rockets.”

OneWeb was thus forced to either accept major delays while waiting for European launch options or look elsewhere. OneWeb was able to secure two contracts for India LVM3 rockets, each carrying 36 satellites, but the company chose SpaceX – the only Western launch provider in the world with large amounts of near-term capacity to spare – to launch three batches of 40 satellites.

After its first SpaceX launch, OneWeb should have 500 working satellites in orbit. Another LVM3 launch and two Falcon 9 launches should leave the company with 616 of 648 planned satellites in orbit. It’s unclear how OneWeb intends to launch the 32 remaining satellites.

OneWeb Flight 15 was SpaceX’s 55th successful launch of 2022, leaving the company just five launches away from achieving a 60-launch target set by CEO Elon Musk in March. Following an unintentional 12-day gap between launches caused by several delays, it’s no longer clear if SpaceX can hit that target. SpaceX has never launched later than December 23rd, and it’s extremely unlikely that the company will be able to launch five more times in the next 15 days. Even if it can break through that apparent barrier, it’s also almost impossible to imagine that SpaceX will be able to launch five more times before the end of the year if each mission continues to suffer days or weeks of technical delays.

Originally scheduled to lift off on November 22nd, 29th, 30th, and December 7th, SpaceX’s next mission – carrying a private Japanese Moon lander – is scheduled to launch no earlier than December 11th. After HAKUTO-R, Spaceflight Now reports that SpaceX has another four launches tentatively scheduled this month.

Tesla Full Self-Driving v14.3.6 review: a rare regression, but some bright spots

Published

on

Tesla released Full Self-Driving version 14.3.6 last week, and after what was potentially one of the best FSD releases in v14.3.5, there has been a bit of a regression. While there are some bright spots, the changes made to v14.3.6 seem to have backtracked some behaviors.

Overall, it is hard to really complain about FSD in any sense; it has revolutionized how I travel literally anywhere. According to my self-driving app, the last time I went a day without using it was 59 days ago.

However, I think it’s also important to recognize when things are just plain bad with FSD. There are times it does truly mind-boggling things, and I’ll dive into those here. Additionally, I only had these issues on local roads, not on highways. Highway operation, generally, is always incredible other than the occasional complaint about speed or left lane camping.

With those things being said, my personal experience may not represent others’ experiences. A handful of people have said they have had a similar experience on v14.3.6, while others have said it is more than normal.

Turning Hesitancy, Inaccuracy

I’ve noticed more inaccuracy turning into multi-lane stretches of road than in any version I can remember. I’ve had at least three instances of FSD turning into a stretch of roadway that has two or more lanes, and not selecting a lane confidently as it has in past versions.

Instead, the car will drive over one of the dashed road lines, and the steering wheel will jerk back and forth before picking the lane. It should be said that it has always picked the correct lane when choosing based on the navigation, but it is still very indecisive. The steering wheel jerking is reminiscent of some of the later versions of v13.

I admit I really hate to see the steering wheel jerking come back. However, I think when Tesla releases v14.3.7, it won’t be present. When there are occurrences of it in FSD versions, it is usually resolved by the following release.

FSD Disregards Manual Turn Signals

This is my biggest bone to pick with FSD other than Navigation issues, but this one seems like it would be such an easy fix.

If Tesla is going to put the word “Supervised” on the end of “Full Self-Driving,” then when I tell the car to do something, it should do it. If I input an increase in speed by pressing the accelerator, the car will immediately respond. It does not disregard my input because it feels it is traveling at the right speed.

FSD should never disobey and turn off turn signals that the driver inputs. Trying to direct the car into the correct lane, I had initiated the left turn signal not once, not twice, but three times, with the car turning it off all three times and continuing in a lane that would end in just one block. The only solution at this point would be to zipper merge.

This goes back to the fact that self-driving’s biggest bottleneck might be rider preference. A zipper merge might have been more than reasonable, might have saved me time that I spent sitting through an additional light cycle, and might be something many drivers would do. I was in no hurry, I traditionally do not try to zipper merge because it feels inconsiderate, and lastly, the car should have just followed my input.

This caused me to disengage and drive manually the rest of the way home. Sometimes I just do not need FSD to try to pass every car it can at intersections.

Bird Braking is a Thing of the Past

The big complaint with recent versions of Full Self-Driving has been what we’ve coined as “bird braking,” which is when the car will brake suddenly as a bird flies past.

There have been zero issues with this so far in v14.3.6, which is an excellent improvement.

FSD Might Already Be Taking Note of Driver Preferences

Another thing I have noticed over the past few days is that v14.3.6 seems to already be taking my preferences with navigation into account.

This is something that is supposed to be rolling out with the Summer Update, but I have a hunch it’s already present and might have been included in this v14.3.6 build. On Friday, FSD pulled into an entrance to a local convenience store that it had never attempted to go into before.

Typically, I manually pull into this entrance because it avoids heavy cross traffic at the main entrance. FSD has always chosen that congested main entrance.

Additionally, FSD has pulled into my assigned parking spot at my townhouse community on multiple occasions with this release. This is something that used to happen ocassionally, but not consistently.

It also navigated back to the same convenience store last night, drove through crazy cars scrambling to gas pumps, navigated out of the parking lot correctly, drove me home, and, once again, parked in my assigned spot.

As previously stated, this release just seems to have a few things that need to be brought to Tesla’s attention, and also to make others who use FSD aware of some things that I’ve experienced. I look forward to the next release that will remedy these issues, just as Tesla has always done in the past.

Musk’s massive Terafab project will get final location soon

Elon Musk’s massive Terafab project, which will be the first true conglomeration between each of his major entities, is set to get its final location soon, the CEO said on Tesla’s recent earnings call.

“The Terafab, we expect to announce a location soon, and provide more details about our plans in that regard. We’ll leave that to the product, the launch announcement rather than try to squeeze it into an earnings call,” Musk said last Wednesday.

Tesla Terafab set for launch: Inside the $20B AI chip factory that will reshape the auto industry

Terafab was announced by Musk back in March and was essentially a massive, vertically integrated semiconductor manufacturing project that would provide all the chips the three companies needed for their AI initiatives without needing third-party companies.

The plant will produce over 1 terawatt of AI compute each year, and will help back up projects like Optimus, Full Self-Driving, and other AI-based projects that Musk’s companies are working on.

In April, less than a month after the project was launched, Intel announced it would join the project, contributing manufacturing expertise and consulting to Terafab as a whole. Intel is one of three chip manufacturers that produce sub-5 nanometer chips at scale. TSMC and Samsung are the other two.

However, there was no true indication of where Terafab would end up, but most believe it will likely be somewhere in Texas. Business Insider has reported that SpaceX plans to build out Terafab in Grimes County, Texas, but this is unconfirmed.

Musk confirmed recently that it would not be on Giga Texas property, as it is simply too large.

Terafab holds much of Musk’s grand ambitions for the future within its construct. It holds so much responsibility for the future and the biggest projects that Musk’s companies can imagine.

“I think this is a very big announcement and it deserves to have its own day in the spotlight and not be squeezed into an earnings call,” he said. “I do think Terafab is going to be an amazing initiative and a necessary one, and one without which we will be constrained in our ability to scale Optimus production, because we simply won’t have enough AI chips.”

He continued by stating that Terafab is necessary for scaling Optimus, which Musk said could be the biggest product of any kind of all time. “It’s crucial to solve that, and we’ll have to solve memory, logic, and packaging in order to scale Optimus.”

Elon Musk reveals SpaceX performed secret Starship test on Flight 13

SpaceX performed a secret test on a specific portion of Starship with its recent 13th test flight last week, CEO Elon Musk revealed.

Starship’s 13th test flight took place last Friday, and in many aspects, it was one of the most overwhelmingly successful launches in the project’s history.

All of the mission objectives were met without incident, both the Super Heavy Booster and Ship managed to perform safe splashdowns in the Gulf of America and the Indian Ocean, respectively, and the deployment of Starlink satellites came and went without any complications.

However, there was more on the agenda for SpaceX with Flight 13. Musk revealed an internal test of the ship’s heat shield tiles, as the space exploration company wanted to push them to the limits after previous issues.

Many noticed that Starship’s initial launch seemed to be more accelerated than normal, and that was not a mistake. Musk revealed that SpaceX decided to give Flight 13 an intentionally aggressive acceleration rate in an effort to test how well the tiles would remain attached to the ship:

SpaceX had issues with some of the heat shield tiles remaining attached early on in the Starship program. The first six test flights presented some kind of anomaly with them, so the company’s big focus with them was to figure out a way to keep them intact through the duration of the flight.

Things truly improved as Flight 10 showed that ceramic tiles generally stayed attached to the ship far better due to refined attachment, as SpaceX utilized pins instead of adhesives. Flights 10 through 13 truly showed some clear progress with the heat shield tiles, and this latest test seems to be where some real progress was noticed, especially by Musk.

The 13th Starship launch last Friday was the second with Starship V3, SpaceX’s latest and greatest iteration of the spacecraft. Goals and ambitions are getting even grander as the project continues to progress. Musk has already hinted that SpaceX will likely try to catch Starship with Flight 14.
