SpaceX may perfect reusable rockets in 2018: Evolution in the Falcons’ Nest

Published

on

2017 has in almost every respect been an unrivaled halcyon year for SpaceX: over the course of its twelves months, SpaceX has returned to flight, begun reusing Falcon 9 boosters, and overall completed 18/18 successful launches and 15/15 first stage recoveries – five of which were commercial reuses of ‘flight-proven’ boosters. It is difficult to fathom how the year could have been more successful, aside from a slight hiccup with fairing manufacturing that may have prevented the launch company from racking up 20 or more missions in 2017.

And yet, despite the flooring and incontrovertible triumphs, I can state with confidence that, barring any serious anomalies, SpaceX’s 2018 docket will utterly eclipse 2017’s varied achievements. This series of articles will act as a sort of preview of SpaceX’s imminent future in 2018, each looking at what the new year may hold for the company’s three most fundamental pursuits: the Falcon rocket family, the Starlink satellite internet initiative, and its ambitions of interplanetary colonization.

Falcon finds its wings

While 2015 and 2016 both saw their own hints of potential successes to come, 2017 is the first year that SpaceX managed a truly impressive launch cadence for Falcon 9 without a serious vehicle failure. Every 2017 launch flew on either a Block 3 or Block 4 iteration of Falcon 9 1.2. Esoteric model numbers aside, this simply means that Falcon 9’s design, manufacture, and operation are all maturing rapidly; SpaceX has clearly learned from the CRS-7 and Amos-6 failures and responded accordingly with a more cautious and tempered perspective.

From a historical perspective, it is extraordinarily impressive that Falcon 9 and Cargo Dragon have experienced such a tiny number of failures over their short but active existences. Both Falcon 9 and Dragon have experienced several miscellaneous teething issues and technical difficulties over their ~7 years of launches, but only three anomalies resulted in failures that catastrophically impacted customer payloads: CRS-1, CRS-7, and Amos-6. Thus, out of a total of 46 Falcon 9 launches, approximately 94% have been complete successes. For perspective SpaceX’s first orbital rocket, Falcon 1, experienced total failures during its first three launch attempts, for a success rate of 40%.

Barring further flight hardware anomalies in the Falcon family, however, 2018 is likely to be even more of a boon for Falcon 9 (and Falcon Heavy). While Falcon Heavy is set to ring in the new year sometime in January 2018, just a few weeks away, far more significant for SpaceX’s launch business is the debut of the “final” iteration of Falcon 9, dubbed Block 5 or ‘V5,’ likely within the next several months. Block 5 has been heavily modified almost entirely for the sake of more efficient reuse, and will feature titanium grid fins (most recently spotted on Falcon Heavy) and several other changes. Altogether, SpaceX’s public goal is to be able to reuse Falcon 9 Block 5 as many as a dozen times with relative ease, and each booster’s lifespan could potentially be lengthened by a factor of 5-10 with more extensive periodic maintenance.

This ‘final’ version of Falcon 9 will almost undoubtedly go through its own period of tweaks, changes, and iterative improvements once it debuts and begins to gather flight experience. Nevertheless, it’s plausible that once its minor problems are ironed out, SpaceX will choose to “freeze” the design and begin to aggressively transfer large sections of its engineering and manufacturing base over to the company’s Mars rocket, BFR. Ultimately, the highly reusable Block 5 evolution of Falcon 9 will allow SpaceX to transfer over its customers to reused rockets and thus recoup the cost of reusability R&D far faster than ever before, both by lowering the material cost of launch and enabling a considerably higher frequency of launches.

Taken as a whole, the culmination of the Falcon family’s evolution will pave SpaceX’s path to realizing its even wilder ambitions of providing ubiquitous and superior satellite internet and transforming itself into the backbone of crew and cargo transport to the Moon, Mars, and beyond. But that’s a story for another day…

While we wish we could jump forward to the end of 2018 and reflect upon even more incredible SpaceX achievements, you can follow SpaceX’s day by day progress live with our launch photographer Tom Cross on Twitter and Instagram @Teslarati. Significant upcoming events include the ever-secretive launch of Zuma (7:57pm EST, January 4) and the inaugural static fire and launch of the titanic Falcon Heavy (no earlier than Jan. 6 and Jan. 15).

Eric Ralph is Teslarati's senior spaceflight reporter and has been covering the industry in some capacity for almost half a decade, largely spurred in 2016 by a trip to Mexico to watch Elon Musk reveal SpaceX's plans for Mars in person. Aside from spreading interest and excitement about spaceflight far and wide, his primary goal is to cover humanity's ongoing efforts to expand beyond Earth to the Moon, Mars, and elsewhere.

Elon Musk drops a Thanksgiving hint about Starship’s biggest test yet

Elon Musk says Starship Flight 15 will try to catch the ship itself, a first.

Published

Elon Musk says SpaceX’s next Starship flight will try something nobody has done before, by catching the ship itself. Speaking to roughly 2,000 people at the X Takeover event at Giga Texas on Saturday, Musk said Flight 15 is about four to six weeks away and “probably launches a little bit before Thanksgiving, is my guess.”

That is a slip from earlier reporting, which had pointed to a launch as early as October 19. Musk explained why the date keeps moving. “We’re making a bunch of improvements to the rocket between every flight,” he said, adding that there are often hundreds, sometimes thousands, of small changes. This time the list is short, “but some of them take a fair bit of work and we’ve got to go inside the tank to make some of these changes.”

“We’re going to try to catch the ship, which is a super big deal,” Musk said. “If we do so, that’ll be the first time that there’s been full recovery of an orbital class rocket.” SpaceX has already caught the Super Heavy booster with the tower’s mechanical arms, and has talked about catching the ship since late 2025, but the upper stage has never been caught.

Musk also laid out what comes after. “The next big milestone would be to refly both the booster and the ship,” he said, describing a Flight 16 where “all parts of an orbital rocket are reflown.”

The reason SpaceX wants this comes down to cost and cadence. Every Starship ship so far has ended its flight in the ocean, and SpaceX expects most of those water landings to end in fireballs. A ship that returns to Starbase intact can be inspected and flown again. SpaceX’s IPO filing, says Starship V3 is designed to deliver 100 metric tons to orbit in a fully reusable configuration, that SpaceX aims to cut the cost to reach orbit by 99% or more versus the historical average, and that tower catches should allow “multiple launches per day.”

The payoff goes beyond cheaper launches. The next generation Starlink V3 satellites are too large for Falcon 9 and can only fly on Starship, which can carry up to 60 per flight. Flight 14 on September 28 deployed the first 26 of them after Starship reached orbit despite an early engine shutdown, as Teslarati reported. Musk blamed engine computer software, and said the heat shield “was extremely robust,” which he claimed in August had solved Starship’s biggest challenge.

NASA’s Moon plans depend on the same capability. NASA’s inspector general has described a lander mission that needs a propellant depot in low Earth orbit and more than 10 tanker flights, with SpaceX targeting one tanker launch every six days. That schedule only works if ships and boosters come back fast and fly again. Also, ship to ship propellant transfer has not been attempted yet.

One interesting hurdle yet to be explored is bringing the ship back to the launch site, with reentry over land, which will undoubtedly come with a lot of aviation safety reviews.

Tesla’s mirrorless Cybercab will give riders a visibility upgrade

Tesla engineer confirms Cybercab update letting riders pull up rear and repeater cameras on demand.

Tesla is working on a Cybercab update that would let passengers pull up the vehicle’s rear and side cameras on demand, and the request came straight from a rider.

The exchange played out on X late Friday. Cybercab rider Dan Burkland shared photos of the two-seater’s cabin screen after an evening ride, praised the UI team’s work, and left one request: let riders open the rear and repeater cameras whenever they want, “especially for peace of mind.” Tesla UI software engineer Evan (@CarCoder) answered with two words: “In development.”

The idea fits a pattern Teslarati has tracked since public rides began. Days after paid Cybercab service opened in Austin, Tesla sent riders a survey that asked them to rate the touchscreen, the app and the cabin, and to pick the features they wanted most. We reported on that survey in September, and a camera view is the kind of small software change Tesla can push quickly if riders keep asking.

It also speaks to something unique about the vehicle. With no steering wheel, no pedals and no driver, passengers have no mirror to check and no way to see behind them. The hardware is clearly built for camera awareness, from the repeater cameras to the rear camera. Letting a passenger look through those same cameras would give a nervous first time rider a way to confirm what is around the car.

The timing matters because the fleet is growing fast. Tesla’s Robotaxi account said on Saturday that more than 300 Cybercabs are now serving Austin, an eightfold increase in 30 days, and Tesla AI chief Ashok Elluswamy named Dallas as the next city. More cars and more cities mean more people riding in a driverless vehicle for the first time, which is exactly when small trust features carry weight.

For now, the feature is confirmed only as in development. If Tesla follows its usual pattern with Cybercab software, riders could see it appear in a point release without any announcement, and Teslarati will watch for it.

Tesla’s Cybercab fleet jumped 8x in a month, with Dallas up next

Tesla confirms its first official Cybercab fleet number as Austin scales fast and Dallas looms.

Tesla says more than 300 Cybercabs are now serving Austin, the first time the company has put an official number on its active Cybercab fleet. The figure came from the Robotaxi account on X on Saturday, which wrote that one month after launch the service had “scaled to 300+ Cybercabs serving Austin – an 8x increase in 30 days.”

Ashok Elluswamy, Tesla’s head of AI software, quoted the post with a line that carried the bigger news. “Two years since the 10/10 Cybercab WeRobot event, the cabs are everywhere in Austin now. Dallas soon,” he wrote. It is the first time Tesla has named the next city for public Cybercab rides.

Tesla opened Cybercab rides to the public in Austin on September 4, as Teslarati reported, a day after an invite only launch event. The ramp since then has been steep. Our September 28 report had the fleet at well over 100 units after availability jumped from 58 to 125 in a single week. On Thursday, Tesla added 150 Cybercabs to the Texas automated vehicle registry, lifting its registered count to 319 from 169. The first seven appeared on the registry on August 31.

RobotaxiTracker, a community site that counts vehicles from sightings and state records, listed 275 vehicles in unsupervised service in Austin on Saturday, 105 of them Cybercabs, which is well below Tesla’s figure. Tracker counts can lag official numbers, though Sawyer Merritt noted that Cybercab wait times in Austin stayed short on Saturday evening even with more than 2,000 fans in town for X Takeover.

Regulators are watching the rollout. NHTSA opened an audit query into Tesla’s certification that the Cybercab meets federal safety standards, and sworn answers are due October 30. Tesla reports third quarter earnings on October 21, which gives the company a natural venue to define its fleet numbers and put a date on Dallas.
