SpaceX has suffered its second rocket landing failure of 2020 despite the fact that both lost Falcon 9 boosters successfully launched 60 Starlink satellites, an anomaly that CEO Elon Musk says will need a “thorough investigation”.

After a rare last-second launch abort on March 15th and a three-day range-related delay, Falcon 9 booster B1048 lifted off with 60 upgraded Starlink v1.0 satellites on its fifth orbital-class mission. At least for the first two and half minutes, the booster performed precisely as intended, carrying a fueled upper stage and its ~16 metric ton (36,000 lb) payload to an altitude of 55 km (34 mi) and a velocity of 1.8 km/s (1.1 mi/s). However, about 10 seconds before the booster reached main engine cut-off (MECO) and stage separation, something went wrong.

While there is some ambiguity in his response, according to Musk, at least one of Falcon 9 B1048’s nine Merlin 1D engines performed an early shutdown before MECO. The rocket’s computer immediately accounted for the anomaly, extending the remaining eight-engine booster burn 5-7 seconds beyond the nominal timeline to ensure mission success. While the booster’s loss is still disappointing and the premature engine shutdown more than a little concerning, it’s critical to remember that mission success was ensured. Just 15 minutes after liftoff, the rocket’s upper stage successfully spun up and deployed another 60 Starlink satellites, bringing SpaceX’s operational constellation to an incredible ~350 satellites.

Based on live views available from SpaceX’s launch webcast, it appears that Falcon 9’s “early engine shutdown” is more of a euphemism for a fairly violent engine failure that triggered an instantaneous cutoff, preventing damage elsewhere. While SpaceX would certainly rather avoid in-flight engine failures, Falcon 9’s nine Merlin 1D booster engines are installed inside an aluminum ‘octaweb’ structure that transmits their thrust to the rest of the rocket but also effectively quarantines each engine in a blast-proof bunker.

Despite the partial failure, Falcon 9 B1048 continued to fight its way through its landing trajectory until it either ran out of propellant or burnt up during reentry. (SpaceX)

Nevertheless, the rocket’s highly-attuned software and affected octaweb engine bunker did their jobs, instantly shutting the failing engine down while also preventing the explosion and resulting shrapnel from damaging the rest of the rocket. More likely than not, B1048’s autonomous decision to always put mission success before booster recovery lead the booster to expend a majority of the propellant needed for its landing attempt to make up for the 10 or so seconds operating at only ~89% thrust.

As a result, B1048 may have simultaneous subjected itself to a much more extreme atmospheric reentry and run out of propellant before it could complete (or maybe even start) its drone ship landing burn. There’s also a chance that the engine that failed was one of the three engines required for reentry and landing burns, an asymmetry that would be impossible to overcome on the fly. Ultimately, the booster likely impacted the ocean at a near-supersonic velocity, smashing it into aluminum confetti. Thankfully, the late B1048 had a record-breakingly productive career as an orbital-class booster, placing dozens of tons of payload into orbit over five successful launches. Its loss is regrettable but the booster has more than earned its keep.

Aside from two twice-flown Falcon Heavy Block 5 side boosters of unknown status and 2-3 new boosters assigned to critical NASA and US Air Force missions, SpaceX’s fleet is now down to just three flightworthy Falcon 9 boosters. This could dramatically limit its options for near-term commercial flights, as none of those rockets – even assuming flawless launch and landing debuts – will likely be ready for their first reuses until May or June. Meanwhile, B1051 and B1049 have three and four missions under their respective belt and both completed their last launches just 50-70 days ago, while B1059 flew for the second time just two weeks ago. Despite the fact that it successfully completed its fifth mission, B1048’s in-flight engine failure will almost certainly delay upcoming launches, although the degree of those delays is up for debate.

Up next for SpaceX is SAOCOM 1B, an Argentinian radar satellite set to become the first payload launched into a polar orbit from the US East Coast in half a century. Before B1048’s anomaly, the mission was scheduled to launch no earlier than March 30th and could use any of unassigned boosters described above

Tesla is opening Cybercab rides to a select few

Published

Tesla has opened a new sweepstakes to allow the public to be among the first to take an initial ride in a Cybercab. This all-electric, steering-wheel-less, pedal-less vehicle is the centerpiece of the company’s autonomous ride-hailing platform, Robotaxi.

There are two ways Tesla fans can get to Austin to take part in the first public rides of the Cybercab: by riding on the Robotaxi platform by August 23, or by mailing a very specific entry to their Headquarters at Gigafactory Texas.

Tesla announced the latter portion of the sweepstakes last night:

Tesla will give one entry into the sweepstakes if you mail a 3″ by 5″ piece of paper with your full name, mailing address, telephone number, email address, and date of birth to their address:

Tesla, Robotaxi Sweeps Event

1 Tesla Road,

Austin, TX 78725

There is a limit of one entry per stamped envelope. You can send as many as you’d like, but they must be in separate envelopes.

The company’s unique strategy to give people the opportunity to ride in a Cybercab before pretty much anyone else outside of the company is a hilarious but spot-on representation of how Tesla operates. In classic fashion, they had the perfect response to the event:

Cybercab will launch later this month, it appears, especially as it plans to announce the winners of the sweepstakes on August 25. The car has already been operating internally, as employees have been able to utilize the Cybercab for rides in some capacity, something it announced earlier this month.

Tesla weirdly confirms Cybercab employee rides, a huge milestone

Moving forward, the big goal is to get Cybercab out on the roads and integrated into the public Robotaxi fleet, one that will pick up real-world ride-hailers and give them a ride from Point A to Point B.

No matter which way you cut it, it appears Tesla is close to putting a vehicle with no steering wheel and no pedals on the road to help people travel autonomously.

You can ride along with us in our first Cybercab ride from the We, Robot event in October 2024. The video is embedded below:

Tesla reveals plans for Robotaxi charging hub in Austin

Tesla has revealed plans through permit submissions for a massive Robotaxi charging hub in Austin, Texas.

Tesla plans to build the Supercharger hub in multiple phases, with the second phase potentially introducing wireless induction charging, something the company has been developing for the Robotaxi fleet.

Initially, 48 Tesla Robotaxi-geared Superchargers will be built on a lot just across from the St. Elmo, Texas, Service Center. There are about 80 additional spots that will not be impacted by phase 1 of the construction process.

Filings show that the second phase of the project will turn those 80 additional spots into wireless charging for Robotaxi, but it might be an error. The Key Notes state that item 3 is listed as “V4 Charging Cabinet to Support 80 Wireless Chargers in Phase 2. However, the drawings point to V3 Cabinets that are already tied to Superchargers:

There are roughly 128 total spots in the lot, but it is unclear if they will all be used for charging based on what appears to be some sort of typo in the blueprint.

This is among the first Robotaxi charging hubs Tesla has started to develop, as it currently has four others planned throughout various areas: one in Phoenix, one in San Antonio, another in Irving, which will serve the Dallas-Fort Worth area, and another in Las Vegas.

These projects are necessary as Tesla expands its Robotaxi program. Now that preparations have started for the public launch of Cybercab, Robotaxi will likely be expanding aggressively, especially over the next two to three years.

Last night, The Information reported that Tesla was planning to launch Cybercab as soon as the end of August. Hours later, Tesla then announced it was launching a competition for fans to potentially ride in Cybercab during its first public rides.

Tesla Cybercab launch preparations have begun

Tesla’s plan to expand its charging infrastructure in the regions where Robotaxi will initially operate is great preparation for the expanding service. There is still a lot to do, including launching the Cybercab on time.

Tesla got its largest order for the all-electric Class 8 Semi yet, a 500-unit order from Einride AB, a Swedish trucking company.

Einride made the announcement this morning following its second-quarter earnings call. The company said it plans to use 500 Tesla Semi units on its fleet intelligence platform, called Saga AI. The deployments will serve large companies like Amazon and will extend Einride’s electric freight network across logistics routes in California, New Jersey, Texas, Illinois, and Georgia.

The deployment is being carried out in several phases over the next two years as Tesla ramps production of the Semi at its dedicated production facility in Sparks, Nevada. Einride will receive its first Semi units in September.

Saga AI

Saga AI is Einride’s dedicated fleet intelligence platform. It enables scaled adoption of electric trucks for freight use and allows shippers to integrate electric capacity without the operational burden or capital risks of managing a fleet. This helps integrate cost-efficient logistics and makes budgeting and forecasting much more accurate.

Tesla Semi’s Adoption

The Tesla Semi is now gathering large-scale clients past those who have helped the company operate a Pilot Program to gain initial information and feedback from real-world drivers.

Perhaps the biggest and most notable is that of Frito-Lay and PepsiCo., who have worked with Tesla for the past several years to dial in the finer details of the truck, including its efficiency and operation-related components.

Tesla Semi gets strange-but-understandable comparison from Jay Leno

There has been tremendous progress in that time, and it even catalyzed Tesla to make some design changes, which were unveiled earlier this year.

But Einride CEO Roozbeh Charli says his company’s partnership with Tesla will continue to push those things forward:

“This deployment is yet another proof point that we can execute at the scale our customers demand. Working closely with Tesla to bring next-generation Semis into active operations quickly and at scale is a testament to the strength of that partnership, and how quickly this technology is maturing from promise to daily operations.”

Tesla Semi is already winning over truck drivers

Additionally, Dan Priestley, the Director of the Semi Program at Tesla, said the partnership is ideal due to Einride’s focus on sustainable transport:

“Einride is at the forefront of sustainable freight, and we are thrilled to deepen our relationship with them through this order of 500 Semis. EV heavy trucks provide lower costs per mile from fuel savings, reduced maintenance, and better uptime over diesel trucks. These savings increase further through operational efficiency when deploying EV trucks at scale, and we are excited that Einride recognizes this and look forward to supporting their deployments.”
