SpaceX’s first dedicated Starlink launch announced as mass production begins

Published

on

SpaceX has announced a launch target of May 2019 for the first batch of operational Starlink satellites in a sign that the proposed internet satellite constellation has reached a major milestone, effectively transitioning from pure research and development to serious manufacturing.

R&D will continue as SpaceX Starlink engineers work to implement the true final design of the first several hundred or thousand spacecraft, but a significant amount of the team’s work will now be centered on producing as many Starlink satellites as possible, as quickly as possible. With anywhere from 4400 to nearly 12,000 satellites needed to complete the three major proposed phases of Starlink, SpaceX will have to build and launch a minimum of ~2200 satellites in the next five years, averaging 37 high-performance, low-cost spacecraft built and launched every month for the next 60 months.

A shift in the Stars

Despite the major challenges ahead of SpaceX, things seem to be going quite smoothly with the current mix of manufacturing and development. As previously reported on Teslarati, SpaceX CEO Elon Musk forced the Starlink group through a painful reorganization in the summer of 2018, challenging the remaining leaders and their team to launch the first batch of operational Starlink satellites no later than June 2019. As a consequence, a sort of compromise had to be reached where one additional group of quasi-prototype satellites would be launched before settling on a truly final design for serious mass-production.

According to SpaceX filings with the FCC, the first group of operational satellites – potentially anywhere from 75 to 1000 or more – will rely on just one band (“Ku”) for communications instead of the nominal two (“Ku” and “Ka”), a change that SpaceX says will significantly simplify the first spacecraft. By simplifying them, SpaceX believes it can expedite Starlink’s initial deployment without losing a great deal of performance or interfering with constellations from competitors like OneWeb.

Somewhere along the line, SpaceX would iteratively improve each subsequent ‘generation’ of Starlink satellites until they reached the nominal performance characteristics outlined in the company’s original constellation application. Knowing SpaceX, improvements would continue for as long as lessons continued to be learned from operating hundreds and eventually thousands of orbital spacecraft.

As one concrete example, recent SpaceX FCC documents stated that the first 75 Starlink spacecraft would feature a less-optimized reentry design, meaning that a select few components will not entirely burn up during reentry, creating debris that poses a slight added risk in the eyes of regulatory bodies like the FCC. After those first 75 spacecraft are built and launched, SpaceX will introduce upgrades – already planned and designed – that will reduce the surviving reentry debris (and thus their risk to humans below) to zero.

While the FCC has yet to grant SpaceX’s requested modifications, the other major goal is to reduce the operating orbit of the first phase of 1584 satellites to 550 km (340 mi), a change that SpaceX says will drastically reduce the potential lifespan of any orbital debris in the unlikely event of their creation. A lower altitude also places a major cushion between SpaceX’s first ~1500 satellites and the orbits of several other planned constellations, including OneWeb and Telesat.

Hello, Production Hell, my old friend

Meanwhile, SpaceX’s Starlink program has begun the often painful steps of transitioning from a venture primarily focused on research and development to one focused mainly on building production lines and supply chains and manufacturing hardware. SpaceX’s Starlink facilities are currently housed in three nearby buildings located in Redmond, Washington, likely offering approximately 150,000 square feet (14,000 m^2) for a mix of office, development, and production spaces. At least one of the three non-office buildings could potentially become dedicated to production while one building – approximately 40,000 ft^2 (~3500 m^2) – has already been completely transformed into a prototype of a Starlink satellite production line, supporting manufacturing for first several dozen quasi-prototype spacecraft. For reference, OneWeb’s dedicated satellite factory will feature around 100,000 square feet of space dedicated primarily to production, while the constellation’s satellites will be roughly half as large as SpaceX’s proposed Starlink satellites (~400 kg, 880 lb).

Mass-producing spacecraft at the scale needed to build even half of those needed for the first phase of ~4400 Starlink satellites will be a feat unprecedented in the history of the space industry. Barring FCC exemptions (possible but unlikely), SpaceX needs to launch ~2200 Starlink satellites between now and April 2024. To complete the first phase, the final number of satellites rises to ~4400. Adding on a proposed constellation of very low Earth orbit (VLEO) Starlink satellites, that number rises once more to a bit less than 12,000. Meanwhile, the cost of the satellites needs to be kept as low as possible while their performance is maximized. To put it in automotive terms, SpaceX needs to find a way to do the satellite equivalent of going from building Tesla’s original Roadster to the 2020 Roadster in just a handful of iterative generations and a few years.

Perhaps SpaceX will be able to garner invaluable insight from the lessons its sister company learned during Model 3’s torturous “production hell”, in which the car company had to grow its production volume by almost a magnitude as quickly as possible. Ironically, it may even be the case that SpaceX has the easier task relative to Tesla.

Tesla Roadster’s new patent preps white-knuckle speeds, keeping it grounded

Published

Ahead of its highly anticipated unveiling, Tesla’s upcoming Roadster received a new patent that aims to keep it grounded while enabling white-knuckle speeds.

The patent, which was granted on September 29, is titled “Electric Car Fan,” bluntly stating its design but not its purpose, which is further detailed in the text of the application. Interestingly, it comes two weeks before the Roadster event, which was delayed due to unfavorable weather on Thursday, which could cause issues, as Tesla revealed the event must be held outdoors.

The purpose is to solve a problem that is relatively unique to high-performance electric cars. Instant motor torque is useless if the tires cannot plant that force, and conventional wings and underbody tunnels generate downforce only when air is already rushing past the car. At launch, in slow corners, and under hard braking from modest speed, passive aerodynamic additions contribute essentially very little to downforce.

Tesla’s filing says that its fans can produce the downforce needed, independent of vehicle velocity, then ease off so the same hardware does not pile on drag at highway speeds, an issue that can come from excessive body modifications.

The hardware outlined in the patent is a ducted-fan package that is placed into the rear of the vehicle. An underbody inlet between the rear wheels feeds a duct that rises to a wide outlet in the diffuser. In that outlet are four axial fans, which are divided by vertical strakes. They will pull air from under the floor and press the chassis onto the pavement.

The language in the patent claims it can cut drag rather than add to it while simultaneously increasing downforce.

Tesla Roadster event requires restricted airspace, and the FAA obliges

The fans run from the high-voltage battery and a vehicle control system, so output can be modulated rather than left on as a fixed penalty.

There are additional strengths that can come from this design, like extra tire load at low speed, which can contribute to even more face-melting acceleration rates, decrease stopping distance, and sharper turn-in before a wing has air to work with. Adjustable fan speed lets the car add grip only when needed, so it can be catered to the force of a turn or acceleration.

These designs were previously used, and banned, in some competitive settings. The Brabham BT46B was banned in F1 competition for using a similar fan design and being labeled as too effective.

Tesla still lists the Roadster as having a sub-two-second 0-60 MPH time and a 250-plus-MPH top speed, and there are expectations for a SpaceX cold-gas thruster package that could not only increase acceleration but potentially cause the vehicle to hover.

It is important to note that a patent is not a production part, and packaging four fans in a rear diffuser, managing noise, and potential debris are all things Tesla must consider. With that being said, the patent being granted shows Tesla is designing the Roadster to go fast, but it is also attempting to use unique strategies to combat any issues it might have at those speeds.

SpaceX turned a heralding moment for Starship into its greatest

Starship reached orbit despite losing an engine, deployed 26 Starlink V3 satellites on Flight 14.

Published

SpaceX’s Starship reached orbit for the first time on Monday, and for a few nail-biting minutes it looked like it wouldn’t. During ascent on Flight 14, one of Ship 41’s six Raptor engines shut down early, and SpaceX’s livestream host Dan Huot told viewers the team had decided not to commit to orbit. Minutes later, after what Huot described as a lot of conversation in the control room, the final poll came back in favor, and a roughly 19 second burn of a single Raptor pushed the ship into orbit about 170 miles up.

The reversal matters because SpaceX had written the exit ramp into the mission plan. The company said it would only fire the orbital insertion burn if flight controllers confirmed enough backup hardware remained for the deorbit burn, a condition Teslarati laid out ahead of the flight. Losing an engine was exactly the scenario that rule was built for.

Pressing forward fits Elon Musk’s history. Falcon 1 failed three straight times before its fourth launch reached orbit in 2008, with SpaceX nearly out of money, and Starship was developed by flying prototypes until they broke. What changed this year SpaceX going public, and with $SPCX sliding below its IPO price in July when Flight 13 slipped, the short interest climbed significantly, as Teslarati reported at the time. A Starship potentially lost today with revenue generating next-gen Starlink satellites aboard would have landed directly on shareholders.

That pressure showed up after orbit. SpaceX cut a flight planned to last nearly 10 hours to about three, moving splashdown from west of Chile to the North Pacific near Hawaii. SpaceX gave no reason, though Musk said this month the company was being extremely cautious about debris risk. The single Raptor for deorbit worked, and Ship 41 completed its flip and landing burn before breaking apart in the water, an outcome SpaceX expected. Musk has structured SpaceX’s governance to shield long term bets from market pressure.

The payload is the bigger business story. Musk posted that all 26 Starlink V3 satellites deployed and are “operating nominally.” Each V3 is rated for about 1 Tbps of downlink and 160 Gbps of uplink, so this single launch adds roughly 26 Tbps, about 10 times what a Falcon 9 load of V2 Mini satellites adds. The V3 is too large for Falcon 9, making Starship the only vehicle that can build out the planned 100,000 satellite constellation, at up to 60 per flight once it reaches routine service. Unlike the 20 V3 units on Flight 13, which reentered on a suborbital path, these will raise their orbits and could begin serving customers within weeks and bring in hundreds of millions of additional dollars in projected Starlink revenue.

SpaceX has already begun winding down Falcon 9 Starlink launches from Florida in favor of Starship. Reported targets put Flight 15 as early as October 19, leaving about three weeks to diagnose Monday’s engine shutdown before the next orbital attempt.

SpaceX just got the green light Starship has waited years for

The FAA has cleared Starship Flight 14, setting up SpaceX’s first orbital attempt on Monday.

SpaceX has cleared the last regulatory hurdle standing between Starship and its first trip to orbit. The Federal Aviation Administration issued the launch license for Starship Flight 14 late Saturday, keeping the mission on track for liftoff Monday, September 28, from Pad 2 at Starbase, Texas.

The 75 minute launch window opens at 7:15 a.m. Central, and Boca Chica Beach closures are also scheduled for September 29 and 30 as backup dates. This will be Starship’s first revenue generating mission.

The license was the missing piece after SpaceX completed a full wet dress rehearsal with Booster 21 and Ship 41 on September 24. At the time, the company said the flight remained on track pending regulatory approval. Because Flight 14 flies an orbital profile, the FAA had to sign off on a modified license that met its safety, payload and financial responsibility requirements.

Observers combing through the new FAA paperwork also noticed that lightning no longer appears among Starship’s listed launch hazards. If that holds, it matters more for where Starship is headed than for Monday’s attempt. Florida and Louisiana, home to LC-39A and the planned Starbase Louisiana site, see some of the most frequent lightning in the United States.

SpaceX tells the FCC that Starship Flight 14 is going to orbit

Flight 14 is the mission SpaceX has been building toward for months. Ship 41 will carry 26 Starlink V3 satellites, the first operational V3 units to be deployed, and attempt roughly six orbits at about 275 kilometers over a flight lasting just under 10 hours. SpaceX says the ship will only perform its orbital insertion burn after flight controllers confirm enough hardware redundancy remains for the deorbit burn at the end of the mission. Ship 41 is targeting a splashdown in the Pacific west of Chile, while Super Heavy will return to the Gulf of Mexico.

The date carries some symbolism as well. A Monday launch would come 10 years and one day after Elon Musk first presented the Interplanetary Transport System, the design that became Starship, at the International Astronautical Congress in Guadalajara, Mexico.

SpaceX has not announced what comes next, but air traffic planning slides reported this week, list Flight 15 no earlier than October 19 and a first Starship launch from LC-39A in Florida no earlier than October 30. Both dates depend on how Monday goes.
