SpaceX sets date for first Florida launch of its kind in more than half a century

Argentinian space agency CONAE says that both its SAOCOM 1B satellite and SpaceX are on track for a type of launch that the United States’ East Coast hasn’t supported in more than half a century.

CONAE has revealed that SpaceX aims to launch the ~2800 kg (6200 lb) radar Earth observation satellite into orbit on a Falcon 9 rocket as early as March 30th, 2020 – late next month. With such a light payload, the Falcon 9 booster – presumably reused – will be able to perform a Return to Launch Site (RTLS) recovery, touching down at one of SpaceX’s two Landing Zone (LZ) pads located at Cape Canaveral Air Force Station (CCAFS). While Landing Zone rocket recoveries have become increasingly rare for SpaceX, that’s not actually why the SAOCOM 1B mission is so unique.

Instead, it’s exceptional because it will be the United States’ first East Coast polar launch in nearly six decades. The mission’s “polar” launch profile refers to the fact that the Argentinian radar satellite will ultimately orbit Earth’s poles, effectively perpendicular to more common equatorial orbits. If successful and repeatable, the mission could ultimately spark a new era for CCAFS and Kennedy Space Center (KSC) and raises big questions about the future of California’s Vandenberg Air Force Base (VAFB) — or at least SpaceX’s presence there.

Previously discussed on Teslarati late last year, the story behind why Cape Canaveral stopped polar launches is quite a weird one. A 2008 article in the Naval History Magazine sums up the events nicely.

“In what somewhat inaccurately became known as “the herd shot around the world,” some..falling rocket debris apparently splattered on a Cuban farm and killed a cow. “This is a Yankee provocation,” accused Revolucion, an official Cuban publication, insisting that the rocket was deliberately exploded over the country. Government radio stations cited the incident as further proof that the United States was trying to destroy the regime of Cuban President Fidel Castro. One cow was even paraded in front of the U.S. Embassy in Havana wearing a placard reading “Eisenhower, you murdered one of my sisters.”

Castro filed a complaint at the United Nations, and Washington sheepishly conceded the possibility that “fragments from the rocket booster” could have landed in Cuba. CIA Director George Tenet later quipped somewhat tastelessly that it was “the first, and last, time that a satellite had been used in the production of ground beef.” Further launches overflying Cuba were postponed, and improvements were made to the Cape Canaveral range-safety system. In any case, it was a dejected NRL group that returned to Washington.”


Naval History Magazine – April 2008

That November 1960 launch thus shut down East Coast polar launches to avoid overflying Cuba and raising the country’s ire near the height of Cold War tensions. It’s believed that the Cape actually launched two more semi-polar missions in the mid-1960s, some five years later, but the fact remains that SpaceX’s prospective March 30th, 2020 launch will mark the United States’ first East Coast launch in more than half a century.

Back in October 2019, while SpaceX had effectively confirmed that it would try to move SAOCOM 1B’s launch from California to Cape Canaveral, CCAFS hadn’t fully approved the change or literally reopened the East Coast’s polar launch corridor. Now, given that CONAE has officially announced a specific launch date (March 30th), it seems safe to say that CCAFS has fully given SpaceX the go-ahead for the launch.

While Falcon 9’s upper stage will still technically overfly Cuba over the course of the launch, the combination of a rare ‘dogleg’ maneuver shortly after launch and the fact that said upper stage will be far above the Earth’s surface have effectively mitigated any technical or legal showstoppers. Around eight minutes after liftoff, the mission’s Falcon 9 booster will also attempt to return to Florida and land at SpaceX’s LZ-1 or 2 landing pad. SpaceX’s October 2018 Vandenberg Air Force Base (VAFB) SAOCOM 1A launch coincidentally marked the first-ever use of Landing Zone-4 (LZ-4), a dedicated landing pad built for SpaceX’s West Coast launch site.

If successful, a polar Falcon 9 launch from Cape Canaveral also raises the question: if SpaceX can potentially perform all conceivable launch profiles from its two Florida pads, why go the effort and expense of maintaining a third pad – entirely dedicated to polar launches – in California? Aside from one lone launch six months later, SpaceX’s last California launch occurred in January 2019 and the next one is expected no earlier than November 2020 – and could very well never happen at all. The only plausible reasons to continue launching from SpaceX’s Vandenberg pad would be if Florida’s polar capabilities were somehow limited or if conservative, bureaucratic customers like NASA and the US military were dead-set on their polar missions only launching from semi-arbitrarily selected launch pads.

Without any modifications whatsoever, Falcon Heavy could also immediately begin performing polar launches from Cape Canaveral, whereas SpaceX would likely need tens of millions of dollars and 6-12 months to modify its California pad to support the massive rocket. Perhaps keeping that pad quietly mothballed and flying launch staff in from Florida and Texas for occasional missions is a much smaller ordeal than it seems. Still, the allure (and efficiency) of a one-stop-launch-shop at Cape Canaveral is almost certainly hard to ignore for a company like SpaceX.

For the SAOCOM 1B launch, the next milestone will be the Argentinian satellite’s arrival at SpaceX’s Florida payload processing facilities, likely to occur within the next week. Already, March is lining up to be an exceptionally busy month for SpaceX, with two separate Falcon 9 launches currently scheduled on March 2nd and March 4th and another Starlink mission likely later in the month. With a little luck, SpaceX might be able to end Q1 2020 with its first four-launch month ever.

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.

Published

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.
