SpaceX CEO Elon Musk updates schedule for first orbital Starship launch

Published

on

SpaceX CEO Elon Musk has presented the first significant update on the company’s Starship program since September 2019, offering a couple of new details about the status of the first orbital launch attempt of the largest and most powerful rocket ever built.

Unfortunately, above all else, the promised update was primarily a rehash of the broad-strokes vision of SpaceX’s Starship and Mars programs, as well as some basic details – most already known – about the rocket, its Raptor engines, and how it will be operated. Nonetheless, a large portion of the event was dedicated to audience questions, some of which actually extracted some specific details from the SpaceX CEO. Perhaps the single most important news: a rough but updated schedule for Starship’s first orbital test flight.

To be clear, a great many questions remain unanswered. Months after Starbase’s first orbital tank farm reached some degree of completion, SpaceX has yet to fill four main liquid methane (LCH4) tanks with even an ounce of fuel. Over the same period, the farm’s five liquid oxygen and nitrogen (LOx/LN2) tanks have been filled with thousands of tons of propellant and coolant. Why is still entirely unclear, save for speculation that SpaceX ran afoul of rudimentary methane storage regulations and is ever so slowly rectifying those errors with modifications. Without so much as a partially operational tank farm, SpaceX will be unable to attempt an orbital Starship launch, let alone start the process of qualifying a Super Heavy booster for flight with wet dress rehearsals (WDRs) and static fire tests.

Musk also failed to confirm or offer an educated guess as to which Starship and Super Heavy booster will support the first orbital test flight (OTF), whether the first OTF will truly reach orbit (rather than ‘just’ orbital velocity), and what will happen to Ship 20 and Booster 4 if – as a great deal of speculation suggests – they’ve fallen out of favor. If they’re to be replaced, it’s also unclear why that is or how long it might take to qualify a new ship and booster given that Super Heavy B4, for example, has yet to attempt a single static fire test a full six months after it first reached its full height.

Nonetheless, largely thanks to questions asked by members of the media, Musk did offer some valuable insight into Starship’s first orbital-class test flight. The SpaceX CEO says that he believes the Federal Aviation Administration (FAA) could complete an environmental assessment of Starbase as early as March. In the same presentation, Musk stated that SpaceX would “hopefully [complete environmental reviews] a couple months.” A lack of environmental approval has been the single most important bottleneck of orbital Starbase launch operations for months. The FAA originally anticipated that those reviews would be complete by the end of 2021 but recently delayed the estimated date of completion to the end of February 2022. Another delay from February to March (or later) has been expected for weeks.

It’s unclear how seamless the whole process will be but SpaceX will also need to receive an FAA license for orbital Starship launches after clearing environmental reviews. That could take days, weeks, months, or even a year or more. If SpaceX doesn’t receive a Finding Of No Significant Impact (FONSI) on its Starbase environmental assessment (EA) and instead has to complete a far more extensive Environmental Impact Statement (EIS), Starbase could be stuck in bureaucratic gridlock well into 2023 or even 2024.

Thankfully, Musk is extremely confident in SpaceX’s alternatives. In the event that Starbase becomes indefinitely unusable, SpaceX has already received full environmental approval to launch Starship out of Kennedy Space Center Pad 39A. The company has already begun the process of assembling a Starship launch and catch tower offsite and Musk believes that a Pad 39A Starship launch site could be brought online in just 6-8 months if SpaceX refocuses all of its Starship resources onto Florida.

The CEO also says that SpaceX’s goal is to have the hardware needed for Starship’s first orbital test flight ready to launch around the same as regulatory approval is secured – “hopefully a couple months for both,” in Musk’s words. If Starship S20 and Booster 4 are still assigned to mission, that schedule is not difficult to believe. Starship has already completed virtually all of the ground testing needed to qualify it for flight, while – from the outside – Super Heavy has never looked more ready for static fire testing.

If SpaceX intends to use a different ship and booster, though, the company will have to cut the amount of time needed for final assembly and qualification testing by a factor of two or three relative to B4/S20. If the next ship and booster pair takes a similar amount of time as B4/S20, the hardware needed for Starship’s first orbital launch attempt might not be ready until August or September 2022. SpaceX will also need to build, test, qualify, and ship around three-dozen Raptor 2 engines, the production of which could singlehandedly take at least six or seven weeks at the current pace of production.

Ultimately, no matter where the cards currently in the air end up falling, it looks like SpaceX has an extremely busy – and hopefully fruitful – year of Starship development and testing ahead of it

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.
