Investigation: One small step for a few, one giant leap for the rest: how to become a European citizen

This is the first of a three-part investigation I co-reported and co-wrote with María Álvarez del Vayo, Ter Garcia, Carmen Torrecillas, and Adrián Maqueda of Civio with help from some EDJNet partners. Part 2, “Stranger in a native landis here. Part 3, “People of no nation: how being stateless means living without rights” is here. The data visualizations are only visible at the Civio website. También hay una versión en español.

Magali Varela de Torres, who moved from Venezuela to Madrid, Spain, in 2017, is the only member of her nuclear family who is not yet Spanish. Her husband was Spanish and now her daughter, son and granddaughter are Spanish, too. Varela de Torres, a retired social worker who has official recognition of disability due to her Alzheimer’s, has lived in Spain long enough to apply for citizenship, too. But Spain’s Ministry of Justice has not processed her requests for a health exemption from the culture test required for naturalisation. Her daughter Adriana Torres has submitted three requests over the last three years and keeps getting the same robotic reply from the ministry asking for information she has already submitted. After listening to her daughter tell the story, Varela de Torres says, “It’s as if I don’t exist.”

NASA’s Lunar Tool-Kit Plans

Engineers today need to understand the surface of the moon in a way that they haven’t since the Apollo era. This year, amidst a flurry of commercial, AmericanIndianJapanese, and other recent missions, the agency plans to expand a tool originally designed as a one-stop shop for satellite missions observing the Earth to cover our celestial neighbor.

Around 2016, NASA’s technology-transfer program began working on a centralized index of Earth Observation (EO) remote-sensing datasets, computer models, and software. This was motivated by a desire to avoid the all-too-possible scenario of a poor young NASA intern being tasked with creating new software to process satellite imagery and then discovering only at the end of the project that another arm of the sprawling space agency had already done the work.

Satellites Are Becoming the New Cellphone Towers

Starlink sent and received texts over a 4G/LTE connection between mobile phones via its latest generation of satellites, called v2mini, for the first time this month, following similar projects from Amazon, Apple, AST SpaceMobile, Huawei, and Lynk Global. Starlink—the satellite constellation operated by SpaceX—will offer text messaging to subscribers of at least eight different mobile-network operators around the world and may offer voice and data coverage without the need for the ground terminals its customers now use in “coming years,” Starlink’s U.S. partner T-Mobile said in a statement.

The Starlink achievement is the latest example of how satellites and cellular base stations are converging. A handful of companies are exploiting cheaper satellite fabrication and launch costs, as well as adapting existing technologies such as beamforming, to bridge the several hundred kilometers between mobile phones and orbiting satellites. Among the many new wrinkles those companies have to iron out is the fact that for the first time, the towers themselves are the mobile component of the network: Low Earth orbit (LEO) satellites move at tens of thousands of kilometers an hour, so they have little time to communicate with any one mobile phone on the Earth’s surface.

The companies competing to solve these problems have so far sent and received text messages on conventional phones via a commercial satellite (Huawei/China Telecom; Lynk Global; Apple/Globalstar) and performed voice and data calls over 5G via an experimental satellite (AST SpaceMobile) as IEEE Spectrum has reported. Investors have taken notice: Lynk Global is going public in a deal that values the company at up to US $800 million while AT&T, Google, and Vodafone recently invested in AST SpaceMobile, which has a market capitalization of $674.6 million.

Diodes at Right Angles Double Autofocus Capacity

In 2013, Canon introduced its first dual-pixel autofocus, a technology that allows almost every pixel in a photo sensor to help focus the image it takes. Now Canon researchers say they’ve developed a new improvement on their previous improvement to autofocus tech. And this new approach finds its focus faster, better, and in lower light—without requiring new components and technologies to be invented first. It simply involves one small twist.
