After multiple days of delays, many a finger is crossed that SpaceX will be able to perform a critical static fire test of Falcon 9 booster B1056.1 on Friday morning (July 19th).

Falcon 9 B1056 and a fresh upper stage are scheduled to launch Cargo Dragon mission CRS-18 no earlier than 7:35 pm EDT (23:35 UTC), July 21st. As always, SpaceX requires each Falcon 9 rocket to successfully perform a static fire ignition test prior to declaring launch readiness, and B1056 was originally planned to be loaded with propellant and fire its nine Merin 1D engines on Wednesday, July 16th.

After a solid handful of slips, the test has most recently been rescheduled on Friday morning, a delay of 48 hours. SpaceX has demonstrated a three-day turnaround between static fire and launch with Falcon 9 Block 5, but a static fire delay beyond Friday – perhaps even beyond early Friday afternoon – will almost certainly push CRS-18’s launch back a day or two. If not, SpaceX is certainly cutting it close to make the current July 21st date.

In support of Cargo Dragon Commercial Resupply Mission-17 (CRS-17), Falcon 9 B1056 launched for the first time on May 4th, roughly 11 weeks (76 days) ago and 78 days before its planned return to flight. For both SpaceX and NASA, CRS-18 will be a fairly significant launch for a variety of reasons

First and foremost, Falcon 9 B1056 previously supported a NASA Cargo Dragon mission, as described above. Even before the booster successfully landed and returned to port, plans were already in order to essentially keep the booster “in family”, reusing it for NASA launches only. Discussed on Teslarati immediately after the subject was broached during a post-launch press conference, NASA manager Kenny Todd didn’t split hairs.

“Quite frankly, [NASA] had a vested interest in this particular booster. We were gonna require it – the intent is to [reuse B1056 on SpaceX’s upcoming CRS-18 launch] and – potentially – CRS-19.”

Not only will NASA fly Cargo Dragon’s CRS-18 mission on B1056, but the agency is already actively considering reusing the same Falcon 9 booster – assuming a successful launch and landing next week – on CRS-19, SpaceX’s second-to-last Dragon 1 (i.e. Cargo Dragon) launch. If all goes well with CRS-18, CRS-19 could come as early as December 2019, while CRS-20 – likely Dragon 1’s last launch ever – is scheduled no earlier than March 2020 and could certainly make use of B1056.3 if NASA is interested.

Meanwhile, although neither SpaceX or NASA have confirmed it, the Cargo Dragon capsule flight-proven Falcon 9 B1056 will itself be flight-proven – although that’s nothing shocking after a full half-dozen successful launches of reused capsules. What will be exceptional, however, is the likely event that CRS-18 will mark the first time that SpaceX has launched the same Cargo Dragon capsule on its third orbital mission.

Speaking all the way back in summer 2017, now two years distant, SpaceX CEO Elon Musk revealed that Cargo Dragon (Dragon 1) was designed at the outset to be reused three times. Almost exactly 24 months later, SpaceX is likely to prove that that is the case. Based on a list of known Dragon 1 capsules and their serial numbers, SpaceX has already launch and reused all but one of the last seven capsules built and successfully recovered. Capsule 107 (C107) supported CRS-5 in January 2015 and was successfully recovered one month later.

Aside from CRS-7 capsule C109, destroyed in June 2015 during Falcon 9’s first and only in-flight failure, all other capsules (C108-C113) have been successfully launched, recovered, and relaunched. As such, it seems extremely improbable that CRS-5 capsule C107 will be supporting CRS-18. Instead, one of SpaceX’s six twice-flight-proven orbital spacecraft has likely been refurbished for the final time, preparing to become the first orbital-class commercial spacecraft to be reused twice.

Finally, it also appears that CRS-18 will mark the debut some sort of on-orbit Falcon upper stage test, hinted at by a grey ring wrapping what looks like just a portion of its fuel (RP-1/kerosene) tank. The objective of this modification is unclear, although chances are good that either NASASpaceflight.com or SpaceX itself will provide at least a bit more information in the coming days.

Tesla is looking to conduct FSD tests in new Swedish city: report

The proposal appears to have been received rather positively by one of the city’s officials.

Recent reports have suggested that Tesla is looking at another city in Sweden to test its Full Self-Driving (FSD) system on public roads. The proposal appears to have been received rather positively by one of the city’s officials.

Tesla FSD tests in Sweden

FSD has already been deployed in numerous territories such as the United States, China, and Australia. However, the system is yet to be released in Europe. As per a recent report from Värmlands Folkblad, Tesla has sent a request for FSD testing to the capital of Värmland, Karlstad. As noted in a CarUp report, Tesla is already testing FSD on motorways after the company secured permission from the Swedish Transport Agency. 

The Municipality of Karlstad has reportedly not issued a decision regarding Tesla’s request yet, though lawmakers seem open to the idea of FSD being tested on public roads. In a comment to VF, municipal councilor Linda Larsson stated that FSD tests in Karlstad “sounds interesting.” Tesla’s FSD tests, if they are approved, will still use safety drivers behind the wheel who will be ready to intervene at any time. 

Tesla pledges to work with the municipality

In its request, Tesla noted that Karlstad is an interesting municipality in which to conduct its tests. The company also stated that it would conduct its operations and tests in close collaboration with the municipality, as well as local entities. Considering the municipal councilor’s comments, it does appear that Tesla might have a solid chance at attaining permission to test FSD on Karlstad’s roads. 

Tesla’s success for FSD tests in Sweden has been mixed. A few months ago, reports emerged stating that the company’s request to test FSD in Stockholm had been rejected by the Swedish Traffic Department.

“The Traffic Office is currently working on updating its approach to automation. At the same time, the city and the office are under heavy pressure from other ongoing innovation tests. Our ambition is to actively participate in and learn from the continued development in the field of automation. 

“Based on this, and in combination with the fact that the current test is the first of its kind, which entails certain risks for both infrastructure and third parties, and that it is planned to be carried out throughout the city, the City of Stockholm considers it is currently not possible to approve the implementation of the test,” the Swedish Traffic Department stated.

Waymo faces federal probe after self-driving taxi fails to stop for school bus

In a statement, a Waymo representative stated that the company has “already developed and implemented improvements” that should help its fleet avoid similar incidents in the future.

Federal regulators have launched an investigation into Waymo’s self-driving vehicles after reports that one of its autonomous taxis failed to stop properly for a school bus. 

The U.S. National Highway Traffic Safety Administration (NHTSA) stated that it’s reviewing around 2,000 Waymo vehicles following concerns that its autonomous systems may have violated traffic laws.

Waymo under review

According to a Reuters report, the NHTSA’s Office of Defects Investigation began the probe after flagging a media report involving a Waymo self-driving taxi that did not remain stationary when approaching a school bus. At the time of the incident, the school bus had its red lights flashing, its stop arm was deployed, and its crossing control arm was extended.

As per the ODI’s report, the Waymo initially stopped beside the bus before maneuvering around its front. This resulted in the vehicle passing the school bus’ extended stop arm and crossing control arm. Students from the bus were disembarking when the Waymo committed the error. The vehicle was operating without a safety driver at the time, and it was equipped with Waymo’s fifth-generation Automated Driving System (ADS).

Software fix already in place

In a statement, a Waymo representative stated that the company has “already developed and implemented improvements related to stopping for school buses and will land additional software updates in our next software release.” The spokesperson also highlighted that Waymo prioritizes the safety of pedestrians, especially children, in its vehicles’ operations.

“Driving safely around children has always been one of Waymo’s highest priorities. In the event referenced, the vehicle approached the school bus from an angle where the flashing lights and stop sign were not visible and drove slowly around the front of the bus before driving past it, keeping a safe distance from children,” Waymo noted.

Waymo, which is owned by Alphabet, operates a fleet of more than 1,500 robotaxis in major U.S. cities, including Phoenix, Los Angeles, San Francisco, and Austin. The company continues to expand its footprint and plans future operations in Tokyo and London.

A major Swedish study has revealed which electric vehicles hold their battery health the best, and Kia and Tesla came out on top. 

Swedish car broker Kvdbil initiated a test of more than 1,300 used BEVs and plug-in hybrids to determine which models retain the best battery capacity over time. Based on the study’s results, the Kia EV6, Kia e-Niro, and the Tesla Model Y were deemed the best.

Kia and Tesla lead the pack

Kvdbil’s test results are bullish for electric vehicles as a whole. The study showed that eight out of ten used electric cars still had at least 90% of their original battery capacity. Kia’s EV6 and e-Niro finished first and second in the rankings, while Tesla’s Model Y came in third. As per CarInfo data, Sweden currently has 12,148 Kia EV6 registered, while there are 48,488 Model Y.

In a comment to the media, test manager Martin Reinholdsson stated, “They are actually better than we thought. We were a bit surprised that there were so many that were this good.”

In a way, Tesla’s strong performance in the test carries extra weight since the Model Y is one of Sweden’s best-selling EVs, giving the test a much larger sample size compared to Kia’s smaller but highly rated fleet.

Battery tech, driver habits, and age all play a role

Kvdbil noted that the test’s standout results could be attributed to advanced battery management systems and careful engineering, as noted in a report from the Sweden Herald. At the same time, the study also found that factors like charging routines, driving style, and the age of a vehicle can influence capacity retention.

Rounding out the top ten were entries from Opel, Mazda, Audi, Fiat, Volvo, Citroën, and Volkswagen, as noted in a CarUp report.

This is not the first time that Tesla’s battery prowess has shown its strength. Last year, reports emerged stating that a Tesla Model S 90D from Chesterfield, UK, had traveled 430,000 miles on its original motors and batteries. Over that period, which was comprised of constant Supercharging sessions due to the car being used as an airport taxi, the Model S 90D only lost 65 miles of range.
