After restarting work on the project a few months ago, SpaceX appears to have gotten back up to speed and begun to make rapid progress on the construction of Starship’s first Florida launch pad and tower.

Located at NASA’s Kennedy Space Center (KSC) Launch Complex 39A facilities, SpaceX has intended to construct a Starship launch site there for several years. A serious attempt was made in late 2019 but SpaceX soon abandoned the effort and redirected its energy towards Starship prototyping and a much different launch pad design. Two years later, SpaceX’s second attempt shares only a little in common with the first. Both are to be located within the eastern half of Pad 39A’s shield-like footprint, although the specific location of the tower and launch mount has been modified. If this attempt comes to fruition, Starship’s first East Coast launch facilities will still sit just a few hundred feet away from the only SpaceX pad capable of launching Crew Dragon, Cargo Dragon, or Falcon Heavy.

Beyond those two characteristics, SpaceX’s second attempt is almost entirely different.

Instead of continuing with an older launch pad design, Starship’s 39A facilities will likely be close to a direct copy of Starbase’s first orbital launch site (OLS), which SpaceX began constructing in earnest in late 2020. It’s safe to assume that some lessons have been learned from Starbase OLS construction and that some modifications will be made to the Florida pad’s design, but no obvious changes are thus far visible.

Most of the visible work SpaceX has done this year centers around the company’s KSC-based Roberts Road facilities, where it has built a major Falcon processing facility and a staging yard for Starship pad construction and broken ground on a massive East Coast Starship factory. At that staging yard, SpaceX began assembling prefabricated sections of Starship’s Pad 39A ‘launch tower’ around March 10th after tower parts began arriving at KSC sometime in February. Within two weeks, SpaceX had completed the basic structure of two tower sections. Another two more weeks after that, around April 11th, a third section had reached a similar level of completion and SpaceX had begun assembling a fourth.

Starbase’s launch tower assembly was carefully tracked by fans like Twitter user @Furqan263, offering an invaluable benchmark for future Starship tower work.

Compared to SpaceX’s Starbase tower assembly, Florida Starship work appears to be proceeding at a similar pace. SpaceX began assembling the fourth Florida tower section about 30 days after starting the first, while Starbase took about 25 days to reach the same point. However, SpaceX does appear to be taking a slightly different approach for Pad 39A. On top of tower section assembly, SpaceX is constructing an extra four sets of the small concrete foundations and steel frames each tower section is assembled on, implying that Starship’s Florida launch tower could be almost entirely prefabricated before SpaceX begins to combine those sections.

That differs from Starbase, where SpaceX rarely constructed more than two or three tower sections at a time before removing and stacking each completed section and beginning to assemble the next on the same foundation and jig. However, while undeniably efficient, SpaceX workers then had to spend months outfitting the tower with plumbing, wiring, additional structure, and more. It’s likely that SpaceX has concluded that it’s better to do as much of that work as possible before the tower is assembled, in which case each Florida section may end up spending more time on the ground. Given the obvious challenges imposed by attempting a major construction project at an active, one-of-a-kind launch pad like LC-39A, it would make even more sense for SpaceX to want to complete as much work as possible before moving Starship pad hardware into the line of fire.

Nonetheless, work will still have to be done at the pad itself. In recent weeks, SpaceX has made significant progress on the foundations 39A’s Starship launch tower and mount require. The bottom half of the concrete base that each steel tower section will eventually sit on has also progressed rapidly. All told, SpaceX is will on its way to replicating Starbase’s orbital Starship launch site on the East Coast, hopefully ensuring that Starship will be able to begin orbital test flights within the next 6-12 months even if the company’s Starbase environmental review continues to be bogged down by bureaucracy.

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

Published

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.
