SpaceX nails first rocket landing by sea in half a year, sends exoplanet probe beyond the Moon

Published

on

SpaceX has successfully completed the first drone ship recovery of a Falcon 9 booster in nearly six months, bringing to an end a what will likely be the final drought of by-sea rocket landings in the company’s history.

B1045’s landing was a particularly stunning example of just how far SpaceX has come. By all appearances, the recovery was easily the smoothest yet achieved by the company, with nary a hint of reentry heating visible in the near-flawless live coverage from a camera aboard the booster. Perhaps of even more interest, the landing itself appeared to be exceptionally luxurious, with the booster gently floating down to its final resting perch aboard the drone ship Of Course I Still Love You.

This return-to-landing, so to speak, is SpaceX’s 24th successful Falcon booster recovery in just over three years of true recovery efforts. The last several months have featured an unfamiliar number of intentionally expendable launches, in which SpaceX chose to preclude any attempt at recovery, instead typically gently landing the boosters in the ocean to gather additional flight-test data and to explore the envelope of Falcon 9’s recovery capabilities. In all cases but one (Hispasat 30W-6), these intentionally expended boosters were older, flight-proven versions of the rocket, versions that hadn’t been designed to economically fly more than once or twice.

B1045, however, has just one flight under its belt, and is already pegged for a second launch with CRS-15, giving the booster as few as 50 days to be refurbished and prepped for its second pre-launch static fire (likely the first week of June). This would be an exceptionally fitting case of foreshadowing for SpaceX’s upcoming Block 5 iteration of Falcon 9. If a Block 4 booster can be launched, landed, and refurbished in well under two months, one can only imagine what a Falcon 9 explicitly upgraded for ease of reuse will be capable of.

Over the past six months, SpaceX has aggressively expanded their program of orbital rocket reuse, leaping from just three operational reflights of Falcon 9 boosters in the process’ first half-year (Mar-Oct ’17) to seven operational reflights between the following months of December and April. Today, April 18, the successful launch of NASA’s Transiting Exoplanet Survey Satellite (TESS) marks the final launch of a new Block 4 Falcon 9 booster (B1045) – although we can expect as many as three additional reflights of recovery Block 4 boosters in 2018, all new Falcon 9 boosters from here on out will be Block 5s, a final upgrade to the rocket designed to significantly optimize reliability and reusability. The first Falcon 9 Block 5 is expected to debut sometime in May, currently No Earlier Than (NET) May 4.

Impressively, despite the fairly extensive modifications and upgrades – both for reliability and reusability – included in Falcon 9 Block 5, SpaceX’s Hans Koenigsmann stated that the lengthy test campaign in Texas went well and was in fact “faster than we’ve ever had on new Block upgrades [of Falcon 9].” SpaceX themselves have not yet given a specific date for the debut of Block 5, but Hans did partially confirm recent reports that it is now targeting a debut in “early May” with the launch of Bangabandhu-1. Put simply, so long as things go more or less according to plan, 2018 will in every conceivable way usher in the real future of orbital-class reusable rockets – perhaps enabling the sort of responsive, cheap, and reliable access to space long ago promised by CEO Elon Musk.

Science galore

Despite its diminutive size and 350 kg mass, TESS is expected to dramatically expand the number of detected exoplanets in the universe, and is tasked with surveying the remaining 95% of the sky left unscanned after Kepler’s famous mission. Ultimately, conservative estimates from astronomers expect TESS to add thousands of new exoplanets to humanity’s current catalog, with perhaps as many as 10% of those discovered likely to be Earth-sized, and thus potential candidates for the first habitable planets to be observed beyond the cozy bounds of our own Solar System.

To give a sense of just how far electronics and satellite technology have improved in the decade since the Kepler observatory was launched (2009), that 1050kg spacecraft was designed to stare specifically at one small segment of the sky (0.25%), scanning it ceaselessly for exoplanets. Despite complex technical difficulties, Kepler managed to discover nearly 1100 confirmed exoplanets, with more than 3000 additional candidates waiting to be confirmed by other spacecraft or telescopes.

On the other hand, the 350kg TESS, has been designed to sca the entire sky and may well double, triple, or quadruple the number of known exoplanets in the universe. Falcon 9 may undoubtedly be a bit like using a dump truck when a shovel would do, but the tiny size of the payload can be thanked for the exceptionally gentle booster recovery and the equally (relatively) easy refurbishment soon to follow.

Tesla makes good on its Cybercab promise in just two weeks

Tesla Cybercab riders can now pull up a rear camera view and darken the screen.

Tesla has given Cybercab passengers a way to see what is behind them, along with a way to turn the cabin screen off entirely.

Riders in Austin can now bring up a live rearview camera feed on the Cybercab’s center display in the middle of a trip. Austin rider Ethan McKanna spotted the change late Friday night, posting from a ride that “You can now open the camera to view what’s behind you in Cybercab!” His photo shows a strip of rear camera video across the top of the screen, with another Cybercab following on a bridge. Sawyer Merritt shared the image Saturday and wrote that it “sounds like” there is also a new quiet mode that darkens the entire screen for riders who want to relax, sleep, or avoid a bright display at night.

The camera view goes beyond the rear feed. Tesla UI software engineer Evan, who posts as @CarCoder, replied to McKanna with a tip: “You can also tap it to see more cameras, and swipe it up or down to hide and show.” Until now, the Cybercab only showed its rear and repeater feeds on the “Please Exit Safely” screen at the end of a ride, so passengers could check for cyclists and traffic before opening a door.


Quiet mode surfaced a day earlier. Austin rider Jackson Blatz posted a video Friday morning of the new Robotaxi interface in a Cybercab with the option. Tesla has not published release notes for either feature.

The rear camera view moved quickly from request to release. Earlier this month, Cybercab rider Dan Burkland asked Tesla to let passengers pull up the rear and repeater cameras whenever they want, “especially for peace of mind.” Evan answered “In development,” as Teslarati reported at the time. About two weeks later, riders have it.

The feature fills a gap created by the Cybercab’s design. With no steering wheel, no pedals, no mirrors and no rear window, a passenger has no natural way to glance behind the car. The eight exterior cameras that feed Tesla’s autonomy software were already on board, so the change only required software.

There is also an AI angle to how it was built. Yun-Ta Tsai, a senior staff engineer on Tesla’s AI team, quoted Merritt’s post and wrote that the “(human) camera view tuning is optimized with Grok and implements part of the algorithm by directly programming the fixed-function hardware, so I don’t even need to check the datasheet.” Tsai did not say which part of the algorithm Grok handled. Grok already plays a bigger role inside the vehicle, with Grok Bot now enabled across every Cybercab and the Model Y Robotaxi fleet after Tesla brought the agent into its cars in September.

The two features join a busy week of changes for riders in Austin, which also brought a redesigned Live Activity for iPhone and Apple Watch and live trip sharing. They also arrive as Tesla prepares the Cybercab for life outside its own fleet. On the third quarter earnings call, Lars Moravy said the company is aiming to deliver Cybercabs to customers before the end of 2026. Tesla has not said whether the camera view and quiet mode will also come to its Model Y Robotaxis.

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.

Concept rendering of Tesla Optimus in mass production

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.
