SpaceX Dragon spacecraft heads to ISS as crewed version preps for debut

Published

on

SpaceX’s third flight-proven Cargo Dragon spacecraft has arrived in orbit and is currently making its way uphill to the International Space Station for the 15th SpaceX resupply, scheduled for arrival around 7 am EDT July 2nd. Meanwhile, the company’s new Crew Dragon is undergoing its own earthbound trials, split between an artificial vacuum chamber and parachute drop tests over the California desert.

Following a twilight launch that brought to a spectacular close an era of older, less-reusable Falcon 9 rockets, the Cargo Dragon capsule trunk full of several tons of supplies and scientific instruments were placed into a parking orbit roughly 200 miles above Earth’s surface, trailed by a mesmerizing rainbow plume created by Falcon 9’s first and second stage over their nine-minute journey.

After arriving in orbit, Crew Dragon separated from Falcon 9’s second stage and officially commenced its second orbital mission roughly 25 months after its first, CRS-9 in July 2016. Alongside the three that have now flown successfully, all five of SpaceX’s remaining Commercial Resupply Services-1 (CRS-1) missions will be conducted with flight-proven Dragon spacecraft, two or three of which will see the already-reused capsules fly a third time before being officially retired.

After SpaceX’s first CRS contract comes to an end, currently scheduled for early 2020 with the CRS-20 mission, the upgraded Dragon 2 will take over all future cargo launches. Dragon 2’s cargo configuration is expected to be a slightly different version of the Crew Dragon capsule and trunk, scheduled to debut as early as late 2018, but the specifics are still somewhat hazy. Most probably, recovered Crew Dragon capsules – unlikely to ever been certified to fly NASA astronauts – will instead be refurbished after their first orbital missions, modified slightly to meet the cargo requirements, and then use to complete SpaceX’s CRS-2 contract alongside their crew transport missions.

While its predecessors continue to grow SpaceX’s experience in orbit, the Crew Dragon program is making its own impressive progress towards the first uncrewed and crewed launch debuts in late 2018 and early 2019. DM-1, the capsule tasked with that first uncrewed demonstration, is likely nearing the end of a suite of tests inside NASA’s huge Plum Brook vacuum chamber facilities, ensuring that the brand-new spacecraft behaves as expected in the extreme environment of space. If successful, the capsule will be sent on its way to Cape Canaveral, Florida to begin true prelight preparations for the first time ever, while its trunk – an expendable structure installed at the base of the craft with solar arrays, radiators, and bays for unpressurized cargo – will be sent back to the Hawthorne, CA factory to be outfitted with flight hardware, after which it will ship to Florida one to two months after the capsule arrives.

 

Meanwhile, the CRS-15 Dragon capsule currently orbiting Earth will dock with the International Space Station early Monday morning and is scheduled to depart, reenter, and return to Hawthorne, CA for Flight 3 refurbishment in early August, at which point the DM-1 Crew Dragon ought to have arrived in Florida. Aside from Dragon, SpaceX has three new Falcon 9 Block 5 launches scheduled between July 20 and August 2, the boosters of which will all be recovered aboard SpaceX’s fleet of drone ships

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.

Tesla just made Service even easier and more convenient

The new feature is rolling out to iOS users now; we have not heard any confirmation from Android phone users whether they are receiving it too.

Tesla just made servicing your vehicle even easier and more convenient than it already is.

All it did was add a new section to its smartphone app.

Tesla has officially launched a new Maintenance tab that estimates the repair date and cost, and uses vehicle data to determine if any part is in need of replacement.

It can be found by accessing the app, going to Service, then hitting Request Service, and then Maintenance.

The new feature is rolling out to iOS users now; we have not heard any confirmation from Android phone users whether they are receiving it too. Since it is not a vehicle capability, we do not believe Tesla will delay the release of the feature to Android phones.

Teslas are already well known for having extremely low maintenance needs, and semi-annual check ups usually only require a tire rotation and some additional windshield washer fluid. There is not a need for things like oil changes or other things that are routinely needed on combustion engine cars due to the lack of parts.

Additionally, the small addition to the company’s smartphone app will help facilitate needs for Service, and could help relieve some congestion, while also streamlining the repair process for technicians.

Tesla to make app change for easier communication following Service

One of the biggest complaints about owning a Tesla is Service wait times, as availability can be extremely limited in some areas. However, Tesla has done a lot to work on increasing the number of Service centers it has, while also working hard to streamline service and make it less time-consuming.

Tesla has aimed to have an F1-style service experience, but it has not worked out that way. With that being said, there are significantly fewer complaints with Tesla’s Service division than in years past. With the presence of Mobile Technicians and more refined Service processes, things are definitely improving.
