SpaceX Starship factory aiming to build five megarockets in 2023

Published

CEO Elon Musk says that SpaceX’s South Texas Starship aims to build up to five of the two-stage megarockets in 2023.

SpaceX’s Boca Chica, Texas hardware endeavors began in an empty field in late 2018, kicking off Starhopper testing in 2019. In late 2019 and early 2020, the company began building the bones of the factory that exists today, relying heavily on several giant tents (“sprung structures”) similar to those used by Tesla. SpaceX has already begun the process of replacing those tents with larger, permanent buildings, but two of the original tents continue to host crucial parts of the Starship manufacturing process.

In terms of useful output, that manufacturing slowed down a bit in 2022. That slowdown can likely be partially explained by the need to move equipment and processes into the first finished section of Starfactory. But in general, SpaceX was simply focused on finishing and testing Starship S24 and Super Heavy B7 – both stages of the latest vehicle meant to attempt Starship’s first orbital launch.

Only by late 2022 did Ship 24 more or less complete proof testing, and Booster 7 is still several major tests away from solidifying full confidence in its design. SpaceX has only conducted limited testing with fully-stacked Starships, further reducing the amount of confidence the company can have in the assembled rocket. Lacking the data needed to know with certainty whether the tweaked designs of Starship and Super Heavy are good enough for several orbital test flights, it’s thus unsurprising that SpaceX only produced a handful of usable ships and boosters in 2022.

But if CEO Elon Musk’s forecast is correct, the company has plans to increase Starbase’s useful output in 2023. According to Musk, SpaceX aims to build “about five full stacks” this year, translating to five flightworthy Starships and five Super Heavy boosters.

In 2022, SpaceX finished Booster 7 and built Booster 8, Booster 9, and most of Booster 10. Booster 8 was almost immediately relegated to the retirement yard. Booster 9, featuring some significant design changes, completed a limited amount of proof testing and returned to the factory in early January – likely for Raptor engine installation. The fate of Booster 10 is unclear, but it stands as a prime example of how fast SpaceX can actually build massive Starship hardware when conditions are right. SpaceX began stacking B10 in late October 2022 and the vehicle is just two stacks away from full height three months later.

In the same period, SpaceX finished and immediately retired Starship S22, finished and began testing Ship 24, finished and began testing Ship 25, and finished stacking Ship 26. Booster 9’s upgrades partially insulate it from the most disappointing possible scenario, retirement before flight. Even if Booster 7 fails during prelaunch testing or its launch attempt, revealing major design flaws, it’s possible that Booster 9’s changes have already addressed those weaknesses, allowing it to continue the flight test campaign. Ship 25’s fate is even more dependent on the fate of Ship 24.

Fitted with Raptor engines, Ship 25 is set to kick off prelaunch testing in early 2023.

In 2022, SpaceX ultimately produced two “full stacks,” with a third (S26/B10) likely to be completed – albeit with a less certain fate – in early 2023. Delivering five full stacks this year – meaning five ships and five boosters that make it far enough to be paired with another and fully stacked – would be a major improvement. However, as was the case in 2022, higher-volume production will remain a risky proposition until the designs of the vehicles being built have been fully qualified.

Given how long it’s taken SpaceX to partially qualify Super Heavy Booster 7, it appears that the largest source of uncertainty will remain for at least another month or two, if not well into mid-2023. Starship production has many uncertainties of its own, and all of them are complicated by not knowing if a Super Heavy booster will be available to launch each new ship in a timely fashion.

Ultimately, an entirely different constraint means that “five full stacks” may be all SpaceX needs to build for the next 12+ months. After a long and painful process, the FAA completed an environmental review of SpaceX’s Starbase, Texas facilities, permitting a maximum of five orbital (full-stack) Starship launches per year. Starship’s FAA orbital launch license, which has yet to be granted, could be even more restrictive. A second Starship pad under construction in Florida is unlikely to be cleared for orbital launches until Starship has proven itself to be moderately safe in South Texas, which could easily take 12-18 months, if not longer.

Combined with the fact that no super-heavy-lift rocket in history has flown five times in its first year of launch activity, a trend Starship seems unlikely to break, SpaceX could practically halt production entirely in 2023 and still have a full year of testing ahead of it while only using Ships 24-26 and Boosters 7, 9, and 10. Unintuitively, that bodes well for a busy 2023 of Starship test flights, as much of the hardware required for three flight tests is already close to completion or almost ready to begin preflight testing.

Why Tesla Roadster unveiling delay might have nothing to do with it flying

Published

on

Tesla announced on Monday that the Roadster event scheduled for today would be postponed due to the need for it to be held outside.

Less than 24 hours later, CEO Elon Musk broadened that by stating it was due to high winds, immediately sending everyone into a frenzy over the Roadster’s potential ability to fly.

And realistically, it could definitely have to do with it flying, hovering, or hopping; whatever Tesla has in mind for this demonstration could not be impacted by wind. However, it might have nothing to do with the vehicle flying whatsoever, and instead could be a simple precaution, as the Roadster is a very unique vehicle with some already official specs that are just mind-blowing.

Tesla will very, very likely be showcasing both the acceleration rate and potentially even a top speed demo at the event in Waco. Both of these demonstrations, performed with a vehicle that has such incredibly fast metrics, could easily be impacted by wind as well.

Tesla Roadster event requires restricted airspace, and the FAA obliges

Top Speed Demo

At high speeds, aerodynamic forces are already overwhelmingly present. A crosswind or sudden gust adds a layer of sideways force that the tires must counter with slip angle. On a short demo course, that force can shove the car off the intended line, especially in a light car with a low frontal area and little mass to resist the push.

Electric cars, due to their battery packs, have an advantage of an extremely low center of gravity, giving them extra stability. However, the speeds at which the Roadster could travel at the demo could spell some issues if crosswinds are present.

Gusts are worse than a steady wind because the load changes faster than a driver can smoothly correct. That shows up as weaving or a late correction. Headwinds and tailwinds can also spell disaster. Headwinds cut a measured top speed but raise the power needed to get there or maintain it. Meanwhile, a tailwind can inflate the top speed, and downforce issues could become more noticeable.

Wind also loads the body unevenly. A low car can feel light on the upwind side or see a sudden change in downforce if the gust hits a wing or diffuser at an angle. Tire temperature and pressure might stay near a normal level, but lateral grip can be lost as the vehicle is spent fighting the wind.

Acceleration Demo

Launch and 0-60 MPH runs are shorter, so the car spends less time exposed to forces that could cause things to go awry. However, the first second is very sensitive, as a crosswind at launch could yaw the car before speed builds and prior to aerodynamic impact being too great. The driver will be required to correct traction control or manage how much the wheels are spinning, which will likely be corrected automatically by some sort of traction control system within the Roadster (we are fairly certain Tesla will implement something brilliant with it).

These things could cause an unstable run.

A headwind would increase drag as speed rises, while a tailwind would do the opposite. Meanwhile, surface effects, like wind-driven dust, light debris, or even rain, could reduce grip at the exact moment the tires are asked for peak longitudinal force. Standing water plus a crosswind is a common reason an acceleration attempt might be scrapped.

Flying or Not

No matter what Tesla has in store for the Roadster, waiting for ideal conditions is a great idea. People who follow and support the company, along with the engineers involved in the Roadster program, have been waiting nine years since the last unveiling for this moment. Everything should be ideal.

Some speculate that it’s just not ready, and that’s ridiculous. Why would Tesla even schedule the event — albeit prematurely — after nine years if it was not ready? Why would they jump the gun now?

We were all excited for today, but it truly is the most ideal thing in the world to wait two more weeks so everything, including the weather, can be perfect. The delay is simply worth it. But Tesla, seriously, make this the last one.

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.
