SpaceX still an option for future Amazon internet satellite launches, says Senior VP

Published

on

An Amazon executive says that the company could still call on SpaceX to launch some of its Project Kuiper internet satellites after two of the three unproven rockets it purchased announced launch delays days apart.

Amazon began work on Project Kuiper in 2018. When SpaceX CEO Elon Musk fired several senior employees overseeing the company’s Starlink satellite internet program for being overly cautious, at least two of those employees immediately landed in senior positions at Project Kuiper. Four years later and more than two years after Amazon received an FCC license to deploy its 3,236-satellite Project Kuiper constellation, which aims to compete directly with SpaceX’s Starlink, the company’s first prototype satellite launch has changed rockets and slipped from late 2022 to early 2023.

Of the 77 firm launch contracts Amazon has signed since April 2021, only nine are for a rocket – United Launch Alliance’s (ULA) Atlas V – that has already successfully flown. The remaining 68 (and another 15 exercisable options) are spread among ULA’s Vulcan Centaur, Arianespace’s Ariane 6, and Blue Origin’s New Glenn, all of which are months away from their first launch attempts.

On October 10th, ULA CEO Tory Bruno told reporters that Vulcan Centaur’s launch debut had slipped from its latest late-2022 target to no earlier than (NET) “early 2023.” Garnering 38 of 77 firm contracts, Vulcan is the single most important rocket for Amazon’s Project Kuiper plans and is likely expected to launch close to half of all Kuiper satellites.

Nine days later, Ariane Group and the European Space Agency (ESA) announced that Ariane 6’s launch debut had also slipped from a late-2022 target. Unlike Vulcan’s gentle early-2023 slip, Ariane 6’s debut was pushed to late 2023 at the earliest, and ESA and Ariane officials frankly admitted that that could easily become 2024. Excluding options, Ariane 6 won 18 Project Kuiper launch contracts and is the constellation’s second most important rocket.

Because Amazon applied for its Project Kuiper license so early, a six-year countdown started when the FCC approved its license in July 2020. If Amazon fails to launch half of its 3,236 satellites within six years of that receipt, the FCC could revoke Kuiper’s constellation license. While it’s unlikely that the FCC would actually revoke the license of a constellation that’s close to achieving its deployment milestones, the deadline still emphasizes just how far Amazon and its suppliers are falling behind.

Vulcan, Ariane 6, and Project Kuiper prototype launch delays have only worsened an already challenging situation. In addition to the rocket’s long-awaited debut, ULA has major obligations to NASA and the US military, who expect Vulcan to complete up to four more launches in 2023. Unless ULA pulls off a minor miracle, it’s unlikely that Vulcan will be able to launch five times in its first year of service. Respectively, ULA’s Atlas V and Delta IV rockets took 2.5 and 3.5 years to reach that milestone. If ULA’s past record serves as a reasonable guide for its future, it’s possible that Vulcan Centaur won’t have the spare capacity to begin Project Kuiper launches until 2025.

The same is arguably true for Ariane 6, which has an even busier manifest – all of which may be delayed to 2024. Of Arianespace’s two most recent rockets, Ariane 4 took 14 months and Ariane 5 took 53 months to complete their first five fully successful launches. Ariane 6 borrows heavily from Ariane 5’s design. Unless Arianespace gets off to a record-breaking start or prioritizes Amazon over ESA and other European operators, an almost unthinkable scenario, it’s difficult to imagine that Ariane 6 will have the spare capacity to begin Project Kuiper launches before 2025 or 2026.

Blue Origin’s New Glenn rocket, which is years behind schedule and unlikely to debut before late 2023 or 2024, might ironically be Amazon’s best bet for the first dedicated Project Kuiper launch, but only if its debut is near-flawless and doesn’t slip any further. Given that New Glenn will be Blue Origin’s first orbital rocket of any kind, more delays and issues (if not an outright failure) on the first launch are likely. New Glenn is thus also unlikely to be ready to launch large batches of Project Kuiper satellites until 2024 or 2025. Given the record of its suborbital New Shepard rocket, the odds are also against Blue Origin quickly ramping up the cadence of a far more complex orbital launch vehicle.

Only Atlas V appears to have any significant chance of beginning large-scale Project Kuiper launches before 2025. But ULA is shutting down Atlas V production to transition to Vulcan, so it’s impossible for Amazon to order more than nine of the rockets, as ULA.

Unfortunately for Amazon, in addition to the many rocket-side issues facing Project Kuiper, its satellite prototype delays will make it even harder for the company to begin large-scale launches sooner than later. SpaceX, now the proud owner of a majority of all working satellites in orbit, took around 21 months to go from launching its first two prototypes to its first batch of 60 operational Starlink satellites. The satellite design it settled on was almost nothing like the first two prototypes.

If Amazon’s first prototypes launch on Vulcan’s early-2023 debut, perform excellently, meet or exceed expectations after just a few months of testing, and are close to the final satellite design, Project Kuiper may still have a shot at manufacturing enough satellites to fill one or more launches in 2024. But if its first satellites run into major issues, Amazon’s decision to “[bring] up manufacturing of…production satellites [in parallel with prototype development]” could set it back months if it’s forced to redesign its satellites, find new suppliers, or significantly change the factory it’s already building.

Combined, Project Kuiper finds itself in an unenviable position. It’s thus unsurprising that as of October 2022, an Amazon executive appears to have changed their tune about using SpaceX rockets. Over the last ~13 months, SpaceX has become the single most productive launch provider in the world, besting the entire nation of China. On a quarterly basis, SpaceX now launches more useful mass to orbit than the rest of the world combined. It’s also the only launch provider on Earth that can create spare capacity for last-minute customers by shuffling its own internal launch demands.

According to Dave Limp, senior vice president of devices and services at Amazon, Project Kuiper is willing to consider taking advantage of some of SpaceX’s unprecedented capabilities after it shunned the company entirely in earlier contracts and statements. Speaking in a Washington Post Live interview, Limp says that Amazon is “open to contracting with anyone” and understands “that heavy launch capacity is [and will likely remain] pretty constrained” for years to come.

Unfortunately, Limp began by falsely asserting that Falcon 9 was too small to have warranted earlier launch contracts, stating that it’s “probably at the low end of…the capacity that we need.” In an expendable configuration, Falcon 9 can launch more than 22 tons (~48,500 lb) to low Earth orbit (LEO), while Ariane 6 is quoted at [PDF] 21.7 tons (~47,800 lb). While it hasn’t flown, SpaceX also offers an extended payload fairing that should more or less match Vulcan and Ariane 6’s largest fairings.

But Limp expressed interest in SpaceX’s Falcon Heavy rocket, which could likely match or come close to the payload volume of Ariane 6 and Vulcan and far exceed either rocket’s performance to LEO. In a configuration that would allow SpaceX to recover all three of Falcon Heavy’s boosters, almost guaranteeing that it would cost less than Vulcan or Ariane 6, the rocket would likely be able to launch around 40-50 tons (90,000-110,000 lb) to LEO. The Amazon executive even brought up SpaceX’s next-generation Starship rocket as a more desirable option for future Project Kuiper launches. Starship is designed to launch anywhere from 100 to 150 tons to LEO, should cost even less than Falcon 9 or Falcon Heavy, and will eventually feature a payload bay that dwarfs even New Glenn’s massive fairing.

Nonetheless, despite the promise of SpaceX, Amazon appears to be in no rush to hedge its bets on Vulcan, Ariane 6, and New Glenn. Only time will tell if its multi-billion-dollar gamble pays off.

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.
