NASA finally succeeds with its Artemis 1 wet launch test

NASA encountered a couple of issues while conducting the Artemis 1 “wet dress rehearsal,” but it still checked off a major milestone by the time the test had ended. The agency was able to fully fuel all the Space Launch System’s propellant tanks for the first time and was able to proceed to terminal launch countdown. “Wet dress rehearsals,” as they’re called, are tests that simulate a rocket launch without the rocket actually lifting off. The launch team had to cut short three previous attempts at fueling the SLS earlier this year due to various leaks and other issues that have already been corrected. 

This attempt wasn’t flawless either: NASA had to put fueling on hold a couple of times since the rehearsal started on Saturday. Fueling was first put on hold on early Monday morning due to an issue with the rocket’s backup supply of gaseous nitrogen. The team was able to repair the valve for the gaseous nitrogen line, however, and fueling recommenced a couple of hours later. As CNN notes, though, a few issues popped up just as the team was finishing up the fueling process on Monday afternoon. They discovered a hydrogen leak and had to find options to seal it after their first solution didn’t work. Plus, the flare stack, which burns excess liquid hydrogen from the rocket, caused a small fire in the grassy area around the launch site. 

In the end, the launch controllers came up with a plan to mask data associated with the leak so as not trigger a hold by the launch computer. That wouldn’t fly in a real launch scenario, but they wanted to get as far into the countdown as possible to gather the data they need. They were successfully able to resume the 10-minute final launch countdown after an extended hold and got to T-29 seconds before they had to end the test completely. The launch team originally planned to let the countdown get to until T-33 seconds before the launch is supposed to occur. They then intended to restart the timer and repeat the countdown until around T-9 seconds before launch. 

Regardless, they successfully performed several critical operations needed for launch during the test, including handing over control from the ground launch sequencer to the automated launch sequencer controlled by the rocket’s flight software. NASA will now assess the data collected from the test to determine whether it can finally set an official launch date for Artemis 1, which will send an unmanned Orion spacecraft on a mission to fly around the Moon, with the earliest possible date being sometime in August. The agency will hold a conference about the test today, June 21st, at 11AM, and you can watch the stream live on its website.

Sony’s new Linkbuds S get their first real discount

Sony only recently launched its $200 LinkBuds S wireless earphones with active noise cancellation, and we’re now seeing the first serious discount. Amazon is selling both the white and black models for $178, for a savings of $22 or 11 percent — a nice drop if you’ve been pondering a pair.

Sony unveiled the open wear LinkBuds earlier this year, but the LinkBuds S offer a more traditional in-ear “closed” design. They resemble Sony’s WF-1000XM4 earbuds, but are smaller and therefore more comfortable to wear for longer periods. Sony in-fact calls them “the world’s smallest and lightest, noise-canceling, hi-res” true wireless earbuds. In addition, they’re IPX4 rated so you can use them for workouts or in bad weather. 

With 5mm drivers, they promise “powerful bass and stunningly clear vocals,” Sony says. They also use the new Integrated Processor V1 found on the new WH-1000XM5 headphones to ensure high sound quality, reduce distortion and augment noise cancellation. They support high-resolution listening via Sony’s LDAC codec and DSEE Extreme upscaling. 

The ANC isn’t as powerful as that found on the WF-1000XM4, but it can still reduce background clamor. It also has a transparency mode so you can hear what’s going on around you and it can adjust that based on your activity or location. Meanwhile, a new feature called Auto Play can automatically play or resume audio based on your activity when you put the earbuds in or complete a call — letting you have a select playlist when you go for a walk, for instance. 

In other words, they’re ideal wireless earphones for everyday use and can adapt to a wide variety of activities. Considering they just launched last month, though, the deal may not last long.

Tesla sued by ex-employees who claim that mass layoffs violated federal law

Tesla is being sued by two former employees from its Sparks, Nevada gigafactory over mass layoffs, Reuters has reported. They claim that more than 500 workers were let go at the plant without the required 60-days of advance notice, in violation of federal laws. “Tesla has simply notified the employees that that their terminations would be effective immediately,” the complaint states. They’re seeking class action status on behalf of any US Tesla employees laid off in May or June without advance notice. 

The US WARN Act requires that companies provide 60-day notice before any mass layoffs, under certain circumstances. The idea is to give employees sufficient time to find other work or retrain. One of the workers who filed the suit, John Lynch, said he was notified on June 10th that he’d been terminated effective immediately.

“Tesla started laying people off in blatant disregard for the WARN act,” attorney Shannon Liss-Riordan (who is representing the workers), told Bloomberg — adding that Tesla only offered one week of severance pay to some employees. She’s preparing an emergency motion in an effort to block Tesla from trying to get releases from employees in exchange for a week of severance pay. 

Following news of the lawsuit, Musk told CNBC in an email that Tesla will be reducing its salaried headcount by 10 percent while increasing its hourly workforce. Salaried workers make up about two-thirds of Tesla employees, so the layoffs will affect around 3.5 percent of workers in total, he said. “A year from now, I think our headcount will be higher in both salaried and obviously in hourly,” Musk added. 

Earlier this month, Musk signaled that job losses were coming after he reportedly told Tesla executives of plans to cut the workforce by the aforementioned 10 percent, saying he had a “super bad feeling” about the economy. Thousands of Tesla workers have reportedly been let go around the US recently and many suffered “devastating economic impact,” according to the lawsuit.

However, Musk told CNBC that the lawsuit wasn’t important. “That is a small lawsuit of minor consequence,” he said. “Anything that relates to Tesla gets big headlines, whether it is a bicycle accident or something much more serious.”

A YouTuber built his own PS5 Slim that’s less than an inch thick

Sony typically follows up its PlayStation consoles with a slim version a few years later, but that time hasn’t come for the PS5 yet. While we all wait for a slimmer PS5 that would fit in small spaces better, a YouTuber called DIY Perks already built one for himself. He took apart a standard PlayStation 5 and replaced everything that needed to be replaced to get rid of the console’s bulk. He substituted components with similar parts and his own home-made creations, including the console’s rather voluminous casing, to come up with a device that’s just 1.9 centimeters thick.

Putting the current device’s power supply and cooling system with the rest of the console’s components wouldn’t yield a “slim” version of the PS5, though. So, what Perks did was build his own water-cooling system and put the power supply in a long, slim external case that can be placed behind the TV, where it won’t be noticeable. While he did run into some issues that took time to solve, he was able to make the console work in the end. His cooling system was even more efficient than the the standard PS5’s, based on the temperatures he took when he tested it out using Horizon Forbidden West. 

Unfortunately, Perks’ PS5 Slim is one of a kind and not easy to replicate. You can check out his process in the video below if you need ideas or just want to be awed.

Canada is banning the sale, production and import of some single-use plastics

Canada is banning companies from producing and importing a handful of single-use plastics by the end of the year, Reuters reports. Among the items the country won’t allow the production of include plastic shopping bags, takeout containers and six-pack rings for holding cans and bottles together.

The federal government will subsequently prohibit the sale of those same items in 2023, with an export ban to follow in 2025. The one-year gap between the initial ban and the one that follows is designed to give businesses in Canada enough time to transition their stock of the listed items. Over the next ten years, the federal government estimates the new regulation will eliminate approximately 1.3 million tonnes of plastic waste, Prime Minister Justin Trudeau said on Twitter.

Not targeted by Canada’s new regulations are plastic fishing nets and lines, which can be far more problematic than single-use plastics like straws and shopping bags. Discarded fishing gear leads to ghost fishing, a phenomenon where those tools continue to trap and kill marine life. With more than 640,000 tons worth of fishing nets discarded every year, it’s a problem that’s only getting worse and one Canada’s plastics ban doesn’t address.

“It’s a drop in the bucket,” Sarah King, the head of Greenpeace Canada’s oceans and plastics campaign, told the CBC. “Until the government gets serious about overall reductions of plastic production, we’re not going to see the impact we need to see in the environment or in our waste streams.”

The ban follows a similar one enacted by France last year and is part of a broader move by governments across the world to curb the production of single-use plastics. In March, the United Nations agreed to begin work on a first-ever global plastic pollution treaty. While the agreement won’t be complete until 2024 at the earliest, it could be among the most significant efforts to curb climate change since the Paris agreement in 2015.

Fitbit will fix frequent disconnections for Charge 5 owners

If your Fitbit Charge 5 has had flaky performance lately, you’ll be glad to hear that a solution is on the horizon. 9to5Google has learned Fitbit is promising a fix for frequent disconnections between the activity tracker and its host phone. If you’re affected, the Bluetooth connection will spontaneously drop and prevent your wearable from syncing fitness data, whether you’re using an Android phone or iPhone.

Reports of the problem first surfaced in January. Common solutions like rebooting the Charge 5 have little effect. Fitbit also hasn’t offered a stopgap solution or indicated the likely culprit.

There’s no timeline for the expected patch, and it’s not clear how many users have the issue. This certainly isn’t what Fitbit would hope for, though. The Charge 5 sits next to the Luxe at the top of Fitbit’s activity tracker lineup, and is competing as much with some lower-end smartwatches as it is fitness devices. The disconnections won’t help the Charge fare well against rivals in a market that still has fierce competition from the likes of Amazfit and Garmin.
