Project Loon flies for 1 million hours

first_img Project Loon headed to help Puerto Rico Automation software collects wind forecast data, builds maps of where to travel and then processes each balloon’s observation so changes can be made to follow that map. It is this software that directs the balloon’s movements, not the 24/7 team of engineers monitoring them, head of Engineering Salvatore Candido said.According to Candido, the first time he saw a balloon deciding to zig where a human would have chosen to zag, he had to “stare for a while at the strategy the algorithm was trying to execute” before realizing he had been outsmarted by the software.”The first balloon allowed to fully execute this technique set a flight time record from Puerto Rico to Peru,” Candido said. “I had never simultaneously felt smarter and dumber at the same time.”Balloons also choose when to loiter in an area to wait for winds to change, and fly in figure 8 patterns to maintain a constant LTE signal over an area for longer periods.

Project Loon Alphabet’s Project Loon has reached the milestone of flying its balloons in the sky for a collective 1 million hours, the company announced Tuesday. This equates to 40 million kilometers travelled.Project Loon delivers mobile connectivity to remote and disaster-ravaged areas, with the balloons operated by a solar-powered pump. They drift on winds at heights of 50,000 feet to 70,000 feet, tacking like a boat to follow air currents. 0 Project Looncenter_img Alphabet says its Loon balloons could beam internet to more people than before Alphabet’s Loon recruits high-powered mobile veterans to serve on board This Loon internet balloon just spent seven months in the air Share your voice Post a comment 1:16 Mobile Sci-Techlast_img read more

Migrant Families Arrive In Busloads As Border Crossings Hit 10Year High

first_img Share Ramon Espinosa/APHonduran migrants surrender to the U.S. Border Patrol after crossing a border wall into the United States. According to new federal data, the number of migrants apprehended crossing the border in recent months has surged.The U.S. Border Patrol apprehended more than 66,000 migrants at the Southern border in February, the highest total for a single month in almost a decade.The majority of those arrested were migrant families or children traveling alone or without a parent, according to figures released Tuesday by U.S. Customs and Border Protection. Many of the migrants say they’re fleeing criminal gangs and poverty in Central America to seek asylum in the United States.“This is clearly both a border security and humanitarian crisis,” said CBP Commissioner Kevin McAleenan at a press briefing.Between October and last week, Border Patrol agents have picked up more than 260,000 people — a 90 percent jump over the same period a year ago.“The entire system right now is at full capacity. Actually, it’s overwhelmed,” said Manuel Padilla, a veteran Border Patrol agent who’s now director of Joint Task Force-West in San Antonio, part of the Department of Homeland Security.Even with the recent climb, illegal border crossings are still well below historical highs. But the makeup of the migrant population has changed dramatically from 20 years ago, when it was mostly single men from Mexico. Border Patrol officials say their infrastructure wasn’t designed for the flood of migrant families and children arriving now.“Everything is maxed out and it’s causing a lot of issues, because the agents are being assigned to areas that are not border security related,” Padilla said, like providing food and medical care for the families and children in their custody.Since last year, Border Patrol agents say, they have routinely encountered large groups of a hundred or more migrants at the border, many of them arriving by bus from Guatemala. According to immigration authorities, the passengers consist almost entirely of families and children who are looking for Border Patrol agents to turn themselves in to. Agents say they’ve encountered 70 large groups since last year.That leaves agents scrambling to transport and process the migrants, Padilla said, and allows drug traffickers to take advantage of the distraction.Humanitarian groups near the border say the surge of migrant families is straining their resources too.“It takes an immense effort to do this,” said Ruben Garcia, the director of Annunciation House, a nonprofit organization in El Paso, Texas, that provides shelter, food and medical care to migrants after they’re released from government custody.Most migrants spend just a few days in El Paso, Garcia said, before joining friends or relatives elsewhere in the country, where they’ll wait for their day in immigration court.President Trump has decried the surge of illegal border crossers from Mexico as “an invasion” — and a chief reason that the United States needs to extend its border barriers.But Padilla, the Border Patrol veteran, believes that a wall alone will not stop these migrants.Many of the migrants are crossing in areas that already have border fencing. And they’re not trying to evade the Border Patrol, Padilla said. In fact, these asylum-seekers are trying to turn themselves in as soon as they set foot on U.S. soil.“So the wall is not going to do anything with this population,” Padilla said. “This requires a legislative fix.”Immigration hard-liners say the U.S. needs to close what they call “loopholes” in the law that allow Central American migrants to avoid quick deportation and that prevent immigration authorities from detaining families for long periods of time.Migrant advocates counter that the Trump administration has made the problem at the Southern border worse by allowing just a few migrant families a day to cross at legal ports of entry. They believe that’s driving many migrants to cross illegally in big groups and in remote stretches of the border.“They’re very vulnerable people,” said Garcia at Annunciation House. “Let’s strive not to lose or let go of our history as a people of immigrants, who are profoundly committed to human rights.”Humanitarian groups and immigration authorities are bracing for even more migrants in the months ahead. The number of illegal border crossers typically crests in the spring, as the temperatures warm.Copyright 2019 NPR. To see more, visit https://www.npr.org.last_img read more
