The news: The UK government will let Huawei continue to play a role in building its 5G networks, but it will be banned from providing equipment for “sensitive parts.”...

The details: Huawei will excluded from all “safety related and safety critical networks in Critical National Infrastructure,” the UK government announced in a statement. It will be allowed to provide only 35% of the peripheral equipment, such as radio masts and antennas, and will be excluded from sensitive areas like nuclear sites and military bases.

Why it’s controversial: The UK has been under pressure from the US, and some of its own politicians and security personnel, to outright block Huawei from its 5G networks over national security concerns. However, it had also been warned by China that it could face significant trade and investment repercussions if it did. Although there is no evidence Huawei has spied on its clients, and the company says it would refuse to do so, the fear is that it could be pressured by the Chinese government to spy on its customers in the future. Cybersecurity chiefs in the US and Australia also claim that over time the difference between the core and periphery in 5G networks will disappear, rendering the distinction almost meaningless.

All about the money: One problem facing the UK government was the lack of affordable alternatives to Huawei, and the fact that many of its major telecoms operators had already purchased Huawei 5G equipment. If it had banned the company, it would have had to start building 5G networks all over again from scratch.

The US reaction: We can expect to see a strong response from the Trump administration, which has been pressuring its allies around the world to ban Huawei from their 5G networks. Newt Gingrich, a former Speaker of the House of Representatives, tweeted that it is a “major defeat for the United States” and a further sign that the country is “losing the internet to China.”

The news: US government use of facial recognition technology should be banned “pending further review,” according to 40 organizations that signed a letter calling for a recommendation to be made to...

The letter, drafted by the privacy advocacy group Electronic Privacy Information Center, or EPIC, cites the recent New York Times investigation of a facial recognition service used by more than 600 law enforcement agencies in the US. The company, Clearview AI, scraped public photographs from Facebook, YouTube, and other websites to create a database of more than three billion images. Such technology, the letter argues, not only risks being inaccurate for people of color but could be used to “control minority populations and limit dissent.” The letter was signed by organizations including the Electronic Frontier Foundation, Color of Change, Fight for the Future, and the Consumer Federation of America, and sent to the Privacy and Civil Liberties Board, an agency within the executive branch. 

The background: EPIC’s letter is one of the biggest efforts so far in the fight to stem the use of facial recognition technologies. Cities including San Francisco and Somerville, Massachusetts, have banned their local governments from using facial recognition, and activists are trying to prevent private companies from deploying the technology too. On the other side of the Atlantic, the European Commission is considering a ban on facial recognition in public for five years. However, London police announced just last week that they would deploy live facial recognition cameras across the city.

Will it work? The letter is certainly another sign that attitudes toward facial recognition are becoming increasingly negative. Democratic presidential candidate Bernie Sanders has called for a complete ban on police use. Legislators in Washington state are considering a bill that would regulate facial recognition in public spaces by both private and public companies. 

The conversation is changing, too. While initial concerns focused on the technology’s accuracy and bias, lawmakers who attended Congress’s third hearing on facial recognition earlier this month have started asking whether the technology should be used even if it were 100 percent accurate

The two companies want to move a 15-year-old satellite into a safer orbit after a battery malfunction put it at risk of exploding. ...

What?! It’s the Spaceway-1 satellite, built by Boeing and operated by DirecTV. Part of a network of three satellites launched between 2005 and 2007, Spaceway-1 used to provide high-definition satellite TV services but is now a backup. All three Spaceway satellites are in geostationary orbit (also known as geosynchronous equatorial orbit, or GEO), 22,000 miles above the surface of the planet. 

Why it might go boom: According to a filing DirecTV sent to the Federal Communications Commission, Spaceway-1 suffered thermal damage to its batteries as the result of a “major anomaly” in December. Boeing did an evaluation that showed “a significant risk that these battery cells could burst” if they turned on.

The threat: The satellite is solar-powered but automatically switches to batteries when sunlight is unavailable. As it happens, Earth is about to head into its bi-yearly eclipse season, when satellites can move into the planet’s shadow. Using the batteries in these phases is “unavoidable,” and there’s no way to extricate the explosive batteries from the rest of the spacecraft. An exploding battery could turn Spaceway-1 into a stream of orbital debris that threatens other satellites. 

Countdown: The FCC gave permission to DirecTV to decommission Spaceway-1 and move it into a graveyard orbit (about 200 miles above GEO) before February 25, the beginning of the next eclipse season. The move should take 21 days, with about seven days left to vent as much propellant as possible. 

Empty the tanks: Satellites that make the graveyard transition are required to empty out their propellant entirely. DirecTV, however, says it won't have time to do this in just seven days, and so the FCC is exempting the company from this rule. DirecTV says it’s looking into some strategies for venting more propellant before it makes its final move into the graveyard orbit, but did not respond to questions asking what these might be.

Other risks: Boeing says the battery malfunction happened as a result of “events that have a very low likelihood of occurring on other satellites.” Neither DirecTV nor Boeing would tell me exactly what damaged the batteries, or to what extent this risk extends to other satellites (including the other two Spaceway satellites).
