Watch SpaceX’s last launch and landing of 2020 live [webcast]

Published

Update: Despite no plans for a preflight static fire, SpaceX remains on track to attempt its last launch and landing of 2020 as early as 9 am EST (14:00 UTC), Thursday, December 17th.

After performing a routine preflight wet dress rehearsal (WDR) and booster static fire prior to every launch since September 2016, SpaceX has gradually begun to loosen the requirement for flight-proven rockets in 2020. Instead, if a prior flight or post-flight inspection reveal issues, static fires will serve more as a data-driven diagnostic tool. For flight-proven boosters with a clean bill of health, so to speak, SpaceX appears to be confident enough to skip the procedure on a few internal Starlink launches and the odd customer mission.

Now, despite NROL-108 begin the NRO’s first direct launch contract with SpaceX and first flight on a flight-proven Falcon 9 rocket of any kind, let alone the four-flight booster assigned to support it, the espionage agency apparently has equal faith in SpaceX. Falcon 9 B1059, a new upper stage and payload fairing, and the unspecified NROL-108 payload(s) went vertical at Kennedy Space Center (KSC) Launch Complex 39A on December 16th – far too late for any WDR or static fire testing prior to an early December 17th launch attempt.

The mission will be SpaceX’s 26th and final launch of 2020 and – barring a major surprise – the last orbital US launch of the year. As usual, SpaceX will broadcast the launch live, with coverage beginning around 15 minutes prior to liftoff (8:45 am EST/UTC-5).

The National Reconnaissance Office (NRO) says that SpaceX remains on track to attempt its last Falcon 9 launch and landing of the year after an almost two-month delay.

Originally scheduled to launch as early as October, the secretive orbital espionage agency’s NROL-108 launch plans were quietly revealed in routine communication permission requests filed by SpaceX with the FCC. Unfortunately, those plans came around the same time as a Falcon 9 booster engine issue aborted a SpaceX launch at the last second and forced the company to undergo a quick but extensive anomaly investigation. As it turns out, the Falcon 9 booster assigned to support NROL-108 (B1059) was practically siblings with the three new boosters affected by the investigation.

SpaceX may have had to swap some of the nine Merlin 1D engines on B1059, although a far less likely outcome given that B1059 had successfully completed four launches and landings at that point. Ultimately, while nothing is known for sure, payload-side issues with the NROL-108 satellite(s) are the most likely cause of most of the eight-week delay that followed. Now, confirmed by the NRO on December 14th, SpaceX is scheduled to launch its second mission for the spy agency no earlier than (NET) 9 am to 12 pm EST (14:00-17:00 UTC) on Thursday, December 17th.

For SpaceX, this will be the third time in a single month that a customer has effectively leapfrogged several Falcon 9 booster reuse milestones, once again exhibiting an extreme amount of confidence in the company’s expertise with flight-proven rockets. On December 6th, Falcon 9 booster B1058 lifted off for the fourth time in support of SpaceX’s CRS-21 space station resupply mission for NASA, marking the space agency’s first launch on a twice- or thrice-flown booster.

On December 13th, carrying a large communications satellite for Sirius XM, another Falcon 9 booster lifted off for the seventh time, becoming the first private customer to launch on a five-flight or six-flight SpaceX rocket.

As few as four days after SXM-7, SpaceX is now scheduled to launch the mysterious NROL-108 mission. It will be the first time the NRO has launched a payload on a flight-proven commercial rocket of any kind, as well as its first launch on a two-flight, three-flight, or four-flight booster – by far the biggest numerical leap a SpaceX customer has ever taken. NRO’s first and only SpaceX launch – technically contracted by spacecraft provider Bell Aerospace, not NRO itself – was completed in May 2017.

While less significant, NROL-108 will also be SpaceX’s first US government launch on a four-flight Falcon 9 booster, yet another indication that even its most conservative customers have fully bought into the value and technical viability of reusable rockets.

After launch, Falcon 9 B1059 will flip around and head back towards the Florida coast for a landing at one of SpaceX’s two East Coast Landing Zones. Deploying a minute or so after booster separation, Falcon 9’s two payload fairing halves are expected to splash down some 330 km (~205 mi) downrange, where SpaceX recovery ships GO Search and GO Ms Tree will attempt recovery.

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.
