Welcome to the latest edition of DeepSpace! Each week, I’ll hand-craft this newsletter to give you a breakdown of what’s happening in the space industry and tell you what you need to know. 

On June 29th, startup Rocket Lab completed its third successful Electron rocket launch this year, placing roughly half a dozen small(ish) satellites in orbit as part of a dedicated mission for Seattle-based startup Spaceflight Industries.

Technically speaking, with three launches under its belt, Rocket Lab has now reached orbit more times this year than the United Launch Alliance’s (ULA) Atlas V and Delta IV rockets combined, despite the fact that the company conducted its first commercial launch just seven months ago. In other words, Rocket Lab is finding its stride with Electron at an unprecedented speed and may be able to complete its tenth successful orbital launch less than two years after the company first reached orbit (January 2018). June 29th’s launch is just the latest in a string of impressive successes for Rocket Lab and the company doesn’t appear to be slowing down any time soon.



Electron Flight 7: “Make It Rain”

  • A tongue-in-cheek reference to the stereotype that it rains constantly in Seattle, home of launch contractor Spaceflight Industries, Electron Flight 7 was a commercial rideshare mission that included six publicly manifested satellites and at least one classified payload.
    • Altogether, the payload mass was reported by Rocket Lab to be roughly 80 kg (175 lb). Aside from marking the orbital debut of Australia’s Melbourne Space Program, Flight 7’s main passenger – manifested via SpaceX – was BlackSky’s ~56 kg (125 lb), dishwasher-sized Global 3 satellite, the third of its kind to reach orbit.
    • BlackSky’s ultimate goal is to build a full constellation of at least 60 Global satellites, each capable of delivering >1000 images with an impressive resolution of ~1m/pixel. The first four (including Global 3) were actually built by Spaceflight itself, but the 60-satellite constellation is to be produced at LeoStella’s recently-inaugurated Seattle factory and replaced every few years.

  • It can be all but guaranteed that BlackSky (or LeoStella) will return to Rocket Lab for future Global satellite launch contracts, perhaps flying 2-3 spacecraft at a time to expedite constellation completion and lower the overall cost of getting it into orbit.
  • Carrying a price tag of roughly $6M, Electron is capable of placing 150 kg (330 lb) into a 500 km (310 mi) sun-synchronous orbit (SSO). 3 Global satellites would likely push Electron to its limits, while 2 would leave plenty of space for additional copassenger spacecraft and thus opportunities to lower the overall cost to BlackSky.
  • Some 50 minutes after lifting off from New Zealand, Electron’s third stage – a “kick stage” powered by a custom-built Curie engine – ignited and burned for about 45 seconds, circularizing its orbit. A few minutes later, all 6-7+ spacecraft were successfully deployed, leaving the kick stage to once again lower its orbit to facilitate a quick and controlled reentry, minimizing space debris.

Onto the next one

  • Pictured at the bottom of the gallery above, Rocket Lab – much like SpaceX – completed a full static fire test of Flight 8’s Electron upper stage, the last major test milestone standing in the way of Electron’s next launch. Located in Auckland, NZ, the upper stage will now be shipped around 300 mi (500 km) south to Rocket Lab’s Mahia Peninsula-based Launch Complex 1 (LC-1).
  • According to Rocket Lab’s website, Electron Flight 8 is scheduled no earlier than (NET) August 2019, although the company’s Flight 7 webcast host indicated that it could happen as early as July.
    • Either way, it appears that Rocket Lab is well on its way to achieving a bimonthly average launch cadence this year.
    • The company’s goal is to reach a monthly launch cadence by the end of the year, roughly halving its current 2019 average of ~50 days between launches.
  • Ultimately, Rocket Lab’s future continues to look brighter month by month. As the only commercial smallsat launch operator currently serving customers, the company is essentially early to the party and has the market cornered by simply being first. Every launch will provide experience and get the company closer to profitability and even greater launch cadences, perhaps as high as 2-3x per month by the end of 2020.

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.
