During a recent NASA council meeting, SpaceX’s response to a Crew Dragon capsule’s April 20th explosion was repeatedly praised by the agency’s senior Commercial Crew Program (CCP) manager, her optimism clearly rekindled after several undeniably challenging months.

On October 29th and 30th, NASA held its second 2019 Advisory Council (NAC) meeting, comprised of a number of (more or less) independent advisors who convene to receive NASA updates and provide a sort of third-party opinion on the agency’s programs. Alongside NASA’s SLS rocket and Orion spacecraft, Commercial Crew continues to be a major priority for NASA and is equally prominent in NAC meetings, where program officials present updates.

On October 30th, CCP manager Kathy Lueders presented one such update on the progress being made by Commercial Crew providers Boeing and SpaceX, both of which are just weeks away from multiple crucial tests. Boeing is scheduled to perform a pad abort test of its Starliner spacecraft as early as November 4th, while SpaceX is targeting a static fire of a Crew Dragon capsule on November 6th. If that test fire is successful, the same capsule could be ready to support SpaceX’s In-Flight Abort (IFA) test in early-December, and Boeing’s Starliner could attempt its orbital launch debut (OFT) no earlier than (NET) December 17th.

For both SpaceX and Boeing, the results of their respective In-Flight Abort and Orbital Flight Test will determine just how soon NASA will certify each company to attempt their first commercial launches with astronauts aboard. If Boeing’s Pad Abort goes perfectly and Starliner’s NET December 17th OFT is also a total success, the company could be ready for its Crewed Flight Test (CFT) anywhere from 3-6+ months after (March-June 2020).

If SpaceX’s IFA test goes perfectly next month, Crew Dragon’s Demo-2 astronaut launch could occur as early as February or March 2020. In April 2019, SpaceX suffered a major setback when flight-proven Crew Dragon capsule C201 violently exploded milliseconds before a planned abort thruster static fire test, reducing the historic spacecraft to a field of debris. Before that failure, C201 had been assigned to perform the in-flight abort test, while capsule C205 was in the late stages of assembly for Demo-2.

Had that explosion never happened and the C201 IFA gone perfectly, Demo-2 could have potentially been ready for launch as early as August or September 2019. Instead, C201’s demise forced SpaceX to change capsule assignments, reassigning C205 to support Crew Dragon’s IFA, while C206 was moved to Demo-2. Nevertheless, as both SpaceX and NASA officials have noted, C201’s on-pad explosion has been viewed as a gift, for the most part, as the capsule failed in a largely controlled and highly-instrumented environment.

In fact, NASA manager Kathy Lueders complimented NASA’s involvement in the anomaly resolution process and repeatedly praised SpaceX’s response to Dragon’s explosion. Although the explosion was an undesirable result, SpaceX’s relentless prioritization flight hardware testing prevented a failure from occurring in flight. Performed alongside NASA, SpaceX’s subsequent investigations and experimentation have essentially brought to light a new design constraint, the knowledge of which many space agencies and companies will likely benefit from.

Most notably, however, Lueders detailed how impressed she was at the incredible speed with which SpaceX was able to respond to Crew Dragon’s catastrophic static fire anomaly.

“So the nice thing is that the SpaceX folks had a bunch of vehicles in flow. So even though we lost Demo-1 [capsule C201], … [SpaceX] was able to pull up what was going to be our Demo-2 vehicle, outfit it, make [necessary] changes [and upgrades] to the vehicle, and get it ready for [flight] with a six-month slip — a pretty phenomenal turnaround.“

Kathy Lueders – NASA – 10/30/19

Crew Dragon C201 exploded on April 20th, 2019. Five months and seven days later, a new Crew Dragon capsule and trunk – having undergone significant modifications as a result of the C201 explosion investigation – were delivered to SpaceX’s Florida facilities for their new role, Dragon’s In-Flight Abort test. Meanwhile, despite the upset and general instability, Crew Dragon capsule C206 – previously assigned to the flight after Demo-2 – is in the late stages of assembly and integration and is expected to ship to Florida for preflight preparations in early-December.

Altogether, those turnaround times are almost unheard of for such complex systems. For example, Boeing’s Starliner service module – generally less complex than the crew capsule – suffered a serious anomaly during a June 2018 static fire test. As a result, Boeing had to fully replace the service module with new hardware and repeat the same test before it could proceed to Starliner’s Pad Abort, at the time expected a few weeks later (Q2 2018).

Like SpaceX, Boeing was forced to cannibalize future launch hardware to re-attempt its static fire test, which was ultimately completed some 11 months after the anomaly on May 24th, 2019. The Pad Abort previously expected in mid-2018 is now expected no earlier than November 4th, 2019, a delay of 12-16 months. In simpler terms, the six or so months that Crew Dragon C201’s explosion has delayed SpaceX’s In-Flight Abort test is an undeniably “phenomenal turnaround” relative to both NASA’s expectations and SpaceX’s peers.

A happy partnership

The day prior, famed ex-NASA engineer and Space Shuttle program manager Wayne Hale – now serving as NAC chair – brought up SpaceX in an entirely different context, deeming the company as a whole a “sterling example” of NASA’s ability to incubate and incentivize commercial spaceflight.

Indeed, SpaceX has radically reshaped almost every aspect of the global spaceflight industry in the ten years since NASA awarded the company its first major contract, proving that orbital-class commercial rockets can be built, landed, and reused – all for far less money than NASA or competitors believed was possible.

All things considered, NASA appears to be more content than ever with the results its fruitful SpaceX partnerships are producing, and a number of senior NASA officials seem to be increasingly willing to unbridle their enthusiasm as a result.

SpaceX readies Starship Flight 14 for a historic journey into uncharted territory

SpaceX finished Starship’s Flight 14 rehearsal, clearing the way for its first orbital flight Monday.

SpaceX has cleared one of the last hurdles before Starship’s first trip to orbit. The company posted on X Thursday afternoon that its launch rehearsal for Flight 14 was complete, keeping the mission on track for Monday, September 28. The launch window opens at 7:15 a.m. CT at Starbase, Texas, and runs for 75 minutes.

A wet dress rehearsal is essentially launch day without the launch. Crews fill Booster 21 and Ship 41 with thousands of tons of extremely cold propellant, run the countdown nearly to ignition, then drain everything back out. It lets engineers catch leaks or equipment problems before anything leaves the pad. SpaceX still needs a launch license from the FAA before the stack, which stands 407 feet tall, can fly.

Flight 14 matters because of where it is going. All 13 previous Starship flights followed a suborbital path, which works like throwing a ball extremely high and far: the vehicle reaches space, but it is always on a course that brings it back down within about an hour. This time, Ship 41 will perform a short engine firing called an orbital insertion burn roughly 25 minutes after liftoff, giving it enough speed to keep falling around Earth instead of back into it. SpaceX plans about six laps at an altitude near 275 kilometers (171 miles) over nearly 10 hours, as Teslarati detailed when the mission was first announced.


Getting into orbit also means Starship has to prove it can get back out. The ship must relight a single Raptor engine in space to slow down for reentry. SpaceX says it will only attempt the orbital insertion burn after flight controllers confirm the hardware needed for that return burn has enough backup, and its flight plan includes health checks that could shorten the mission to two or five orbits.

Flight 14 is also the first to put working satellites into service. Flight 13 carried 20 Starlink V3 satellites in July, but they came back down with the ship because that mission never reached orbit. This time, 26 V3 satellites are meant to stay up and join the constellation within a few weeks. Together they add about 26 terabits per second of network capacity, which SpaceX says is roughly 10 times what a single Falcon 9 launch of older V2 Mini satellites adds. Three of them carry cameras that will photograph Starship’s heat shield in orbit to check for tile damage before reentry.

The hardware has changed too. Ship 41 flies with extra fasteners on tiles in the most vulnerable areas, fixes for gaps where superheated plasma slipped behind tiles, and curved tiles designed to reduce heating between them. Two tiles recovered from Ship 40 will fly again, the first reuse of any part of a Starship heat shield. Booster 21 carries better engine filtering and new relight software after ice clogged three center engines on the previous booster, leaving only eight of 13 engines to restart for its landing burn.

Ship 41 is targeting a splashdown in the Pacific Ocean west of Chile, a new recovery zone after several Indian Ocean landings, while Booster 21 aims for the Gulf. Neither will be caught by the tower on this flight. Elon Musk said in August that a ship catch was likely “in a few months.”

Google just picked SpaceX for its first step into orbital AI

Google will launch its first Project Suncatcher AI satellite on SpaceX’s Transporter-18 rideshare next week.

Google is about to put its own AI chips into orbit for the first time, and it is paying SpaceX to get them there.

The company said Thursday that the first in-orbit test of Project Suncatcher, its research effort to find out whether space can host large-scale AI computing, will fly next week on SpaceX’s Transporter-18 rideshare mission.

The satellite, called MVP, is about the size of a refrigerator and carries four of Google’s Tensor Processing Units, the same chips Google runs in its ground data centers. Google originally planned to launch two custom satellites in 2027, but chose to move faster by integrating its chips into a satellite.

MVP’s solar panels supply about one kilowatt of power, and Google will run Gemini models on the TPUs only in bursts of roughly 15 minutes before the chips shut down so the radiators can shed heat. In a blog post, Google said its Trillium TPUs survived vibration testing that mimicked sustained launch loads of up to 10g, with individual components seeing 50 to 100g, and handled a radiation dose greater than a five year mission would deliver.

SpaceX and Google mull massive partnership on Musk’s orbital data dream: report

Next week’s flight, slated for October 1, follows a relationship that became public in May, when Teslarati reported that Google was in talks with SpaceX for a launch deal tied to orbital data centers. Google also holds a stake of roughly 6% in SpaceX.

The two companies are chasing the same idea from very different starting points. SpaceX’s own orbital compute program is built around the AI1 satellite, a roughly 70 meter structure derived from Starlink V3 hardware that is designed for 150 kW of peak compute, about 150 times the power MVP will draw. Elon Musk has brushed off concerns about crowding orbit with those satellites, and SpaceX is building its Gigasat factory in Bastrop, Texas, to produce them, targeting an annualized rate of about 1 GW of space compute by the end of 2027.

Musk also posted on X on Thursday that “the amount of compute in space will obviously round up to 100% of all compute.”

Google has been more cautious in public. Its research estimates that launch prices need to fall below about $200 per kilogram before an orbital data center can compete with a ground facility on energy cost, a threshold the company believes could be reached around the mid 2030s. The Suncatcher team has said it expects the effort to remain a project rather than a product for years, which leaves the first real test of its hardware riding on a rocket from the company with the most aggressive timeline in the field.

Tesla Cybercab gets initial tie-in to localized, in-house cathode plant

Published

Tesla has taken another concrete step toward owning its battery supply chain, and it’s doing so with what is perhaps the most important vehicle in its short-but-storied history.

On September 23, Tesla announced that it has officially built the first Cybercab with cathode material produced in-house at the company’s first cathode plant in the U.S., and the first in the U.S. overall.

Active cathode material is the most expensive piece of a lithium-ion battery cell, and it often accounts for more than a third of cell cost. For years, the industry sourced a majority of it from Asia, but Tesla’s decision to make it in the United States bodes well for the Cybercab project. This is the latest chapter in Tesla’s vertical integration strategy, which began in public at Battery Day in 2020.

At the Battery Day Event, Elon Musk said the company would build a North American cathode plant and overhaul the process to cut costs and waste, while also making some of the most powerful and long-lasting cells in the industry.

The Austin facility took years to appear. Tesla filed permits for “Project Cathode” in 2022 on land near Giga Texas. By mid-2022, the building frame was up and Tesla later invested hundreds of millions of dollars as part of a larger expansion of the Giga Texas plant. The company stated it was operating the first large-scale cathode production facility in North America to supplement 4680 cell production.

One month later, that material reached a finished Cybercab.

The timing of this breakthrough is monumental for the Cybercab program. As Tesla officially launched the first Cybercab rides to the public earlier this month, production of the ride-hailing-geared vehicle is moving forward on the planned S-curve that CEO Elon Musk told everyone to expect.

Nevertheless, packs of Cybercab units have been spotted throughout the United States, in an effort to potentially activate the fleet as soon as the company gains regulatory approval in various geographic areas.

On top of that, Tesla owning the cathode step and pairing it with its own in-house lithium from the Gulf Coast refinery shortens the supply chain that once stretched thousands of miles and subjects every pack to fewer external price shocks and geopolitical risks.

Tesla is not yet independent of all of its foreign suppliers, as some precursor metals come from mines and chemical plants. But the first in-house cathode Cybercab shows the company is closing the most expensive and most concentrated gap in its battery production efforts. For a vehicle like Cybercab to operate at a high utilization within the Robotaxi network, that control over cost is so crucial.

It is arguably as important as the software that drives it.
