In a surprise turn of events, SpaceX has decided to send Just Read The Instructions (JRTI) – one of the company’s two autonomous spaceport drone ships (ASDS) – from Port of Los Angeles to either the Gulf or East Coast.

The likely destination: either Port Canaveral, Florida or Port of Brownsville, Texas. This move comes as the company enters a major lull in launch activities from its West Coast SLC-4 pad, situated in California’s Vandenberg Air Force Base (VAFB). Lacking manifested launches, SpaceX has gone as far as redistributing almost all of its VAFB-based launch team and laying off those that could not move to Texas or Florida. As early as the first half of 2020, this major move east could easily culminate in the end of all West Coast SpaceX fleet activity, aside from a rare fairing retrieval or two.

On June 12th, SpaceX successfully launched what is expected to be its last West Coast mission for at least 6-9 months, while drone ship JRTI was most recently used to recover a VAFB-launched Falcon 9 booster during the January 11th launch of Iridium NEXT-8. Unexpectedly, it appears that Falcon 9 B1049.2’s landing aboard JRTI will be the drone ship’s last West Coast recovery for quite some time.

On August 1st, the approximately 300 foot by 170 foot converted barge departed its well-worn Port of Los Angeles berth behind tugboat “Alice C”. In fact, the drone ship’s departure went unknown for a solid 12-24 hours before a member of the unofficial SpaceX subreddit (/r/SpaceX) discovered paperwork filed with the Panama Canal Authority for an August 15th passage.

Back in January 2019, SpaceX fairing recovery vessel Mr. Steven (now GO Ms. Tree) – in a bit of what now is obvious foreshadowing – began a very similar ~5000 mi (8000 km) journey, traveling from Port of LA to Port Canaveral via the Panama Canal. Mr. Steven, however, is a far faster ship and sustained a solid 15-20 knots (17-22 mph) over the entire voyage, while drone ship JRTI – towed the entire way – will have to suffice with an average speed less than half that.

Where to?

Assuming a day-long canal passage, JRTI’s journey to Port Canaveral or Brownsville would take no less than three weeks (~22 days) from start to finish, indicating a likely arrival at the unknown final destination in the third week of August. The two probable destinations, Texas and Florida, would both arguably make sense.

In Florida, SpaceX drone ship Of Course I Still Love You (OCISLY) is now tasked with handling the vast majority of SpaceX’s non-LZ booster recoveries, including Falcon Heavy center cores. In February 2018, CEO Elon Musk noted that a third drone ship (aside from JRTI & OCISLY) was “under construction” with the intention of allowing SpaceX to conduct Falcon Heavy launches where the center core is expended and both side boosters land at sea.

Perhaps SpaceX analyzed its fairly short West Coast manifest and decided that it would be even faster (and cheaper) to simply send JRTI East. Falcon Heavy’s next (public) launch is scheduled no earlier than late 2020, ruling out that as a primary motivation, but SpaceX is also about to begin operational Starlink launches that will demand an unprecedented cadence. Starlink’s cadence requirements could be so high that a second dedicated drone ship is necessary to prevent SpaceX’s internal manifest from delaying and generally disrupting its customers’ launches, thus explaining JRTI’s move.

At the same time, the spectacular pace of SpaceX’s orbital Starship prototype construction could very well demand the use of a large ocean-based landing platform in the near-term, at least according to Elon Musk’s recent comments on the subject of the first Starship test flights. Per Musk, either or both of SpaceX’s two Starship Mk1 (technically Mk1 & Mk2) prototypes could be ready for their first significant flights as early as September 2019, initially targeting altitudes of at least 20 km (12 mi).

Somewhat coincidentally, Starship’s tripod fin-legs – circa. a September 2018 design update – would actually almost fit inside the span of a Falcon 9 booster’s deployed landing legs (~18m diameter). This is to say that SpaceX’s two drone ships may already be large enough (give or take) to support Starship and Super Heavy booster landings. Given that the SpaceX plans to eventually put one or both of the in-work orbital Starship prototypes through an increasingly intensive series of high-speed, high-altitude (but still suborbital) tests before the first orbital flights, a drone ship may be necessary for the same reasons that not all Falcon 9 boosters can conveniently return to land during recovery.

Regardless of the ultimate purpose of drone ship JRTI’s move, it is undoubtedly a sign that things are about to get even more interesting and exciting in the world of SpaceX.

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.
