Loon sets stratospheric sustained flight record with 312 day balloon trip

Alphabet’s Loon, the company focused on creating new networking capabilities using stratosphere-based infrastructure, has set a new world record for a continuous stratospheric flight. One of Loon’s ultra high-altitude balloons flew for 312 days straight, beating the existing record of 223 days by a considerable margin, and nearly racking up a full year of sustained time aloft.

The balloon in question took off from Puerto Rico in May 2019, and then made its way to Peru where it took part in a service test for three months, it then headed south over the Pacific Ocean, and finally ended up in Baja, Mexico for a landing in March this year. Loon’s CTO Sal Candido said in a blog post that the record-setting flight that it’s the result of the company’s continued work on advancing its technology and pushing both hardware and software forward in new and innovative ways.

Part of that means learning as much as possible from balloons that break records like this one, and Candido points out that Loon has a unique advantage over more traditional high-altitude balloons designed for weather observation because it recovers just about all of them, and can study the best performers in extreme detail. That allows it to replicate and improve on what’s going right when balloons are staying aloft for long periods.

Long-lasting stratospheric balloons are useful because they mean that Loon can provide connectivity to target area for longer, at lower costs, which hopefully means more affordable connectivity for everyone, including those in hard-to-reach areas where ground infrastructure is prohibitively expensive. There’s plenty of additional potential for science, Earth observation and weather tracking/modelling, but Loon’s squarely focused on the connectivity piece of the puzzle at the moment, and replicating this will help tremendously in that regard.

Uber co-founder Garrett Camp steps back from board director role

Uber co-founder Garrett Camp is relinquishing his role as a board director and switching to board observer — where he says he’ll focus on product strategy for the ride hailing giant. Camp made the announcement in a short Medium post in which he writes of his decade at Uber: “I’ve learned a lot, and realized that I’m most helpful when focused on product strategy & design, and this is where I’d like to focus going forward.” “I will continue to work with Dara [Khosrowshahi, Uber CEO] and the product and technology leadership teams to brainstorm new ideas, iterate on plans and designs, and continue to innovate at scale,” he adds. “We have a strong and diverse team in place, and I’m confident everyone will navigate well during these turbulent times.” The Canadian billionaire entrepreneur signs off by saying he’s looking forward to helping Uber “brainstorm the next big idea”. Camp hasn’t been short of ideas over his career in tech. He’s the co-founder of the web 2.0 recommendatio

Drone crash near kids leads Swiss Post and Matternet to suspend autonomous deliveries

A serious crash by a delivery drone in Switzerland have grounded the fleet and put a partnership on ice. Within a stone’s throw of a school, the incident raised grim possibilities for the possibilities of catastrophic failure of payload-bearing autonomous aerial vehicles. The drones were operated by Matternet as part of a partnership with the Swiss Post (i.e. the postal service), which was using the craft to dispatch lab samples from one medical center for priority cases. As far as potential applications of drone delivery, it’s a home run — but twice now the craft have crashed, first with a soft landing and the second time a very hard one. The first incident, in January, was the result of a GPS hardware error; the drone entered a planned failback state and deployed its emergency parachute, falling slowly to the ground. Measures were taken to improve the GPS systems. The second failure in May, however, led to the drone attempting to deploy its parachute again, only to sever the line

ProtonMail logged IP address of French activist after order by Swiss authorities

ProtonMail , a hosted email service with a focus on end-to-end encrypted communications, has been facing criticism after a police report showed that French authorities managed to obtain the IP address of a French activist who was using the online service. The company has communicated widely about the incident, stating that it doesn’t log IP addresses by default and it only complies with local regulation — in that case Swiss law. While ProtonMail didn’t cooperate with French authorities, French police sent a request to Swiss police via Europol to force the company to obtain the IP address of one of its users. For the past year, a group of people have taken over a handful of commercial premises and apartments near Place Sainte Marthe in Paris. They want to fight against gentrification, real estate speculation, Airbnb and high-end restaurants. While it started as a local conflict, it quickly became a symbolic campaign. They attracted newspaper headlines when they started occupying prem
