Elon Musk says SpaceX is still building a third drone ship – but is it for Falcon or Starship?
Unprovoked on October 9th, SpaceX CEO Elon Musk tweeted “A Shortfall of Gravitas” – the name of a third drone ship settled on a year and a half ago – and reaffirmed that plans were still afoot to build a third rocket recovery vessel.
This is the first update on SpaceX’s newest drone ship in more than a year and comes just a few months after drone ship Just Read The Instructions (JRTI) – formerly stationed in California – was sent East through the Panama Canal. News that A Shortfall of Gravitas (ASOG) is still in the works raises the questions: what’s the holdup and what role(s) will the new drone ship play in SpaceX’s rocket recovery fleet?
Back in July 2018 and just shy of half a year after ASOG’s development was revealed, CEO Elon Musk indicated that the drone ship could be completed and ready for recovery operations as early as “next summer”, or Q3 2019. Now two weeks into Q4 2019, this can be interpreted in several ways, with the most likely explanation being that SpaceX’s naval contractor of choice is running behind schedule while building the new drone ship.
That’s the simplest explanation and operates under the assumption that Musk’s February 2018 comments remain true, meaning that ASOG is first and foremost (if not entirely) meant to support dual side booster landings for future Falcon Heavy launches and an increased Falcon 9 flight rate. However, recent developments give reason to believe that this may no longer be the guiding motivation behind SpaceX’s construction of a new drone ship.

Most notably, over the last several months of 2019, it has become increasingly clear that SpaceX plans (or hopes) to shut down its West Coast Vandenberg Air Force Base (VAFB) launch facilities for anywhere from 9 to 18 months. In just the last few days, word broke that Cape Canaveral Air Force Station (CCAFS) believes that it will be able to open an East Coast polar launch corridor (essentially the same thing VAFB offers) just months from now, and SpaceX hopes to be its first user as soon as February 2020.
Possibly along those lines, SpaceX took the step of sending West Coast drone ship JRTI on a several-week journey across the Panama Canal. The drone ship has since stopped in Louisiana for what is assumed to be maintenance and it remains unclear if JRTI will head to Port of Brownsville (Texas) to support Starship test flights or to Port Canaveral to fill the role ASOG was initially meant to.
As such, it’s no longer clear if SpaceX actually has a need for ASOG, at least as it was described last year. If SpaceX is moving JRTI east for the indefinite future, OCISLY and JRTI could easily support the Falcon 9 launch rates needed for Starlink and dual Falcon Heavy side booster recoveries, although Falcon Heavy is not scheduled to fly again until late-2020.
This leaves one obvious option left to explain ASOG’s continued existence and delayed debut: SpaceX may have paused work for a variety of reasons and changed ASOG’s design to account for a new role in the recovery fleet. That new role would likely center around the extremely rapid progress SpaceX is making with Starship as it pursues a series of ambitious flight tests that could begin before the end of 2019.

Of note, an August 2019 Draft Environmental Assessment (EA) of East Coast Starship launches revealed that SpaceX’s initially plans to land all Super Heavy boosters on a drone ship stationed a few miles off the Florida coast. Starship may also require drone ship landings in the early stages, at least until SpaceX is able to complete the environmental review and licensing process needed before it can begin to land Starship/Super Heavy at Pad 39A and Landing Zones 1 and 2.
For now, we’ll have to wait and see where drone ship JRTI heads after its Louisiana interlude and hopefully find out soon whether ASOG is a drone ship copy or something else entirely.

Tesla shows what Roadster drivers will see on screen before thruster activation
Tesla’s Roadster video reveals a fighter jet inspired cockpit with a 5,500 PSI thruster gauge.
Tesla has given future owners their clearest look yet at the cockpit of its next generation Roadster. In a 34 second video posted to X on Friday afternoon, the company walked through the car’s touchscreen with a caption: “Inspired by fighter jet cockpits, Roadster’s interface was designed around the pilot.”
The clip opens on a black screen with red graphics and a 3D wireframe of the car, which sits beside the Roadster’s squared off yoke. Tapping parts of the model brings up controls for the rear wing, including low drag and high downforce positions, along with a charging page with a charge limit bar and a small music player. A row of tabs along the bottom reads Home, Vehicle, Listen, Climate and Navigate.
Most of the video is spent in Track Mode. The dashboard shows a live circuit map, a list of session lap times, brake and motor temperatures, and pressure and temperature readouts for each tire. A setup page lets the driver pick Auto, Low Drag, High Downforce or Custom aero modes, adjust aero balance and brake balance, and switch stability and traction control off. Along the bottom, a status bar reads “Thruster · 5,500 PSI” next to a “Boost Ready” indicator.
That gauge ties the software to the hardware Tesla showed off near Waco, Texas on October 15. The Thrust and Rocket versions use cold gas thrusters fed by carbon overwrapped pressure vessels, and Tesla lists 0 to 60 mph times of under 0.9 seconds and under 0.59 seconds for them, as Teslarati detailed in its breakdown of the three Roadster configurations. The base Performance car relies on a fan and ground sealing system for grip, and the aero settings on screen match the active wings and suction setup covered in our look at how the Roadster generates downforce.
The Roadster layout is a departure from the rest of Tesla’s lineup. Instead of a map centered screen, the Roadster puts the car itself at the center of the home page, and Tesla’s Roadster page lists two smaller forward displays alongside the main touchscreen. Tesla has not said whether any of the Track Mode telemetry will make its way to the Model 3 Performance or other vehicles.
The interface could still change before deliveries. Elon Musk said at the event that Roadster production will begin in 2028, and Tesla says the flagship Rocket version is not approved for public road use. Reservations are open with a $50,000 payment, while Thrust is listed as a limited release and Rocket is invite only.
Those who want to see the car in person will get their first chance this weekend. The Roadster goes on display in the lobby of the Petersen Automotive Museum in Los Angeles from October 24 to 27, according to Sawyer Merritt, the first time the public will be able to view it up close.

Tesla reveals Optimus Academy, where robots teach themselves
Tesla has begun building production quality Optimus robots in Fremont and revealed its training plan.
Tesla has started building Optimus on the high volume line it set up inside its Fremont factory, and the company says the robots coming off it are the first that meet the bar for a real product. “The bots coming off this line are the first production-quality bots that we have manufactured,” Tesla wrote in its third quarter shareholder letter, adding that it has “proven that the current manufacturing process for Optimus is suitable for a commercial product.”
The line sits in space that built the Model S and Model X until this spring. Tesla cleared the old vehicle line in 46 days, as Teslarati reported in July, to make room for robot production sized for one million units a year. On Wednesday’s earnings call, Elon Musk said most of the equipment for that capacity is already in Fremont, with output set to climb toward roughly 20,000 robots a week as the line ramps.
Musk described the ramp as a classic S curve. “The growth of Optimus is an S curve, but the initial curve is a shallow slope,” he said. The team is now refining the robot’s AI, electromechanical design, reliability and service life, and Musk expects that work to be finished by the end of next year, when Tesla plans to start delivering Optimus to outside companies for dangerous, repetitive and around the clock jobs.
The most interesting part of the call was how Tesla plans to teach the robots. Its cars send real driving data back to the AI team from millions of vehicles, but Optimus has no fleet like that yet. “A big difference with Optimus versus the cars is we don’t have this vast fleet of cars from which we can gather training data,” Musk said. Tesla’s answer is an Optimus Academy, where 10,000 to 20,000 robots will practice a wide range of tasks and feed what they learn into the next version of the model. Every unit off the Fremont line becomes a source of that training data.
Smarter hardware is on the way too. Tesla plans to put its AI5 chip into Optimus next year, and Musk said a new Optimus video should arrive within one or two months showing the robot completing tasks driven by AI rather than preprogrammed motions. He took aim at rival humanoid demos that only run scripted routines, saying those would not hold up in the real world.
The supply chain is lining up behind the program. In September, Tesla certified Tuopu, Joyson and Sanhua as mass production partners for Optimus components. A far larger Optimus factory is also rising at Giga Texas, where drone footage from Joe Tegtmeyer showed the steel frame nearing completion, and Musk has pegged that plant’s long term target at 10 million robots a year.
Tesla executives also said Optimus production costs are trending toward the expected manufacturing cost of Cybercab, a sign the robot is being engineered for volume from the start. The hands remain the toughest piece of the design, a point Musk also made at the X Takeover event earlier this month, as Teslarati covered at the time, and that is where much of the current engineering effort is focused.

The Starship moon landing number NASA and Elon Musk can’t agree on
Musk disputes NASA estimate of 22 Starship launches for Moon landing, predicting 6 to 8.
Elon Musk is disputing a new NASA safety panel estimate of how many Starship launches it will take to put astronauts on the Moon, saying the real number will be less than half the panel’s figure.
On Thursday, NASA’s Aerospace Safety Advisory Panel held its quarterly public meeting. Panel member Charlie Precourt, a former NASA astronaut, flagged the fueling process for SpaceX’s lunar lander as a major risk for Artemis IV, the mission planned to land a crew on the Moon in 2028. “We need to keep our eyes on numerous required fuelings for the lander,” Precourt said, according to Ars Technica. “I think the last estimate is around 22 flights.”
Ars Technica’s Eric Berger posted the comment on X, and Musk replied. “That’s way too high,” Musk wrote. “Actual number will be more like 6 to 8.”
The disagreement comes down to a basic problem with sending a ship as large as Starship to the Moon. Starship burns nearly all of its propellant just reaching Earth orbit, so it cannot continue on to the Moon without stopping for a refill. SpaceX’s answer is a gas station in space. First, a Starship that works as a storage tank, called a depot, is launched into orbit. Then a series of tanker Starships launch one at a time, dock with the depot and pump their leftover propellant into it. Once the depot is full, the lunar lander version of Starship launches, docks, fills up and heads for the Moon.
Every tanker trip is its own full rocket launch, which is why the count matters. More launches mean more time, more cost and more chances for something to go wrong before astronauts ever leave Earth. Berger estimated that even if SpaceX reaches twice weekly Starship launches by the end of 2027, filling a depot at the panel’s number would still take roughly three months.
How many tankers are needed depends mostly on how much propellant each one can carry to orbit and how much is lost along the way. Starship’s fuel and oxygen are stored at extremely cold temperatures, and some of it slowly boils off while waiting in orbit. More is lost in each transfer. NASA appears to be working from what Starship can lift today, while Musk’s range assumes a more capable rocket.
Musk has pushed back on higher counts before. In 2021, after a government document suggested 16 launches, he called that “extremely unlikely” and said eight tankers would be the most required.
Much of the answer depends on hardware SpaceX has not finished flying. As Teslarati noted earlier this year, the company plans to carry out the refueling process with its upgraded V3 Starship, and Precourt described Artemis IV as carrying “a large number of firsts.” He also praised NASA Administrator Jared Isaacman’s team for working to clear obstacles for both SpaceX and Blue Origin, whose Blue Moon lander does not rely on orbital refueling for its first mission.
