SpaceX’s drone ships near return-to-action with Block 5 Falcon 9 landings

Published

Teslarati photographer Pauline Acalin’s recent trips to drone ship Just Read The Instructions’ berth in Port of San Pedro shows that SpaceX technicians are nearly done preparing the hibernating vessel for a return to Falcon 9 rocket recoveries in the Pacific Ocean, a ten-month drought likely to end for good on July 20th.

Although it’s hard to believe, SpaceX’s West Coast autonomous spaceport drone ship (ASDS) has been effectively marooned at its Port of Los Angeles berth for more than nine full months, with the vessel’s last recovery occurring just after the October 9 launch of ten Iridium NEXT satellites, the fourth of five SpaceX Vandenberg launches in 2017 (and the fourth of four West Coast booster landings).

Three months after that October mission and booster recovery, SpaceX expended their next California launch and marked the beginning of a streak of eight missions where flight-proven Block 3 and 4 boosters could have been recovered but no attempts were made. While intermixed with the spectacle of Falcon Heavy’s dual side booster landings at LZ-1, the debut launch and recovery of Falcon 9 Block 5, and two other Block 4 booster recoveries, the majority of SpaceX’s launches since December 2017 have been treated as expendable – put simply, the company decided that recovering and refurbishing twice-flown boosters of older Falcon 9 blocks was not worth the effort and expense.

Instead, those well-worn boosters were expended in the Pacific and Atlantic Oceans after partially supporting a series of experimental tests designed to gather additional data on the recovery envelope of SpaceX’s partially reusable rockets. The rationale makes sense – SpaceX fundamentally sacrificed some of its older, less-reusable Falcon 9 boosters for the sake of knowledge that may allow their highly reusable Falcon 9 Block 5 predecessors a better chance of successfully landing even after exceptionally fast, hot, and high-energy recoveries, a necessity if the upgraded rockets are to be reused 10 to 100 times, as is the goal.

Although Just Read The Instructions spent several months without a full complement of maneuvering thrusters, thanks in part to efforts to keep its besieged East coast sister Of Course I Still Love You operational, photographer Pauline Acalin’s photos over the last several months show that the vessel now has four full thrusters installed and ready to bring it back into rocket recovery action in the Pacific Ocean.

Still, the abrupt return to expendable rocket launches after a year – 2017 – filled to the brim with 18 of 18 successful launches and 14 of 14 successful landings led to a decidedly fascinating vein of disapproval in the SpaceX enthusiast and broader spaceflight fan communities – people had grown accustomed to the adrenaline-soaked thrill of routine Falcon 9 rocket landings. Some expressed worries that regularly and intentionally expending large hunks of metal in the ocean could harm their ecosystems and was tantamount to littering. None the wiser, every other launch provider in the world continues to expend all of their rocket boosters without any attempts at recovery like the nearly all non-Shuttle rocket launches in the past six decades, and their tepidly reusable next-generation rockets are unlikely to even begin attempting hardware recovery until the mid-2020s at the earliest.

Frankly, SpaceX’s abrupt successes with orbital-class rocket recovery struck a chord with observers, demonstrating just how intuitive attempting to recover expensive rocket hardware really is, while also bringing into clear focus the actual insanity of failing to try and of the seemingly ad-hoc rationalization of expendable rocketry. Thankfully, we still have SpaceX, and the company’s spate of rocket booster sacrifices is likely just one expendable launch away from coming to an effective end for the indefinite future, with that particular launch – CRS-15 – scheduled less than two weeks from now, on June 29th.

After CRS-15, which will probably see its twice-flown Block 4 booster expended in the Atlantic, a combination of Block 5 Falcon 9s and Heavies will theoretically bring to an end the practice of expending orbital rocket boosters, at least on SpaceX’s watch. Considering that the upgraded boosters have been designed and built to launch as many as ten times with minimal refurbishment and potentially 100+ times with regular maintenance, the opportunity cost of an expended Block 5 rocket booster is so high that it is difficult to imagine SpaceX will be easily swayed to expend one until it’s flown at least several times prior.

We here at Teslarati eagerly await the imminent demise of expendable rockets, set to begin in earnest – at least for SpaceX – around July 19th and 20th with two Falcon 9 Block 5 launches on two coasts, one with Telstar 19V (Florida) and the other with Iridium-7 (California).

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

Published

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.
