There are more than 2,000 active satellites orbiting Earth. At the end of their useful lives, many will simply burn up as they reenter the atmosphere. But some will continue circling as "zombie" satellites — neither alive nor quite dead.

"Most zombie satellites are satellites that are no longer under human control, or have failed to some degree," says Scott Tilley.

Tilley, an amateur radio operator living in Canada, has a passion for hunting them down.

President Trump says the U.S. has reached an agreement with Canada to limit nonessential travel across their mutual border, as governments and people around the world grapple with the growing novel coronavirus pandemic that has upended daily life and sent shockwaves through the global economy.

Developments in the past 24 hours came as the worldwide total of confirmed infections from the virus was set to top 200,000, with some 8,000 dead from the resulting COVID-19 disease.

Here's a look at developments by region:

Afghan forces, the U.S.-led coalition in Afghanistan and the Taliban militia will begin a seven-day "reduction in violence" across the country beginning Saturday midnight local time (2:30 p.m. ET Friday) — a possible prelude to a broader peace deal following two decades of war, according to U.S. and Afghan officials.

The quasi cease-fire was hammered out during protracted negotiations in Qatar that began in 2018. It could ultimately lead to a significant reduction of the approximately 12,000 U.S. troops in Afghanistan.

At least 10 people were killed by a gunman in western Germany late Wednesday at several locations, including two hookah lounges frequented by ethnic Kurdish customers. The suspected shooter, who was later found dead, left a letter and video claiming responsibility, according to multiple German news agencies.

The suspect had reportedly posted materials online that were vehemently anti-immigrant, prompting federal prosecutors to take over the case.

China's Hubei province expanded its criteria for identifying new coronavirus infections on Thursday, causing a dramatic spike in reported cases at the epicenter of the disease, as Beijing moved to purge provincial party officials amid criticism of their handling of the epidemic.

Daniel arap Moi, who ruled Kenya for nearly a quarter century marked by repression and widespread corruption before he eventually yielded to multiparty democracy and allowed a peaceful transfer of power, has died at age 95.

His death was announced by current President Uhuru Kenyatta, the son of the country's founding father and first president, Jomo Kenyatta, whose death in office in 1978 paved the way for Moi's rise.

The Environmental Protection Agency is dramatically reducing the amount of U.S. waterways that get federal protection under the Clean Water Act — a move that is welcomed by many farmers, builders and mining companies but is opposed even by the agency's own science advisers.

Iran's U.N. ambassador tells NPR that Tehran has no plans to step up a confrontation with the U.S. after it fired missiles at U.S. military bases in Iraq in "a measured, proportionate response" to the assassination of Maj. Gen. Qassem Soleimani.

However, Majid Takht Ravanchi, speaking to Morning Edition host Steve Inskeep, says Iran is prepared for further action if the U.S. renews its aggression. He also denied the Trump administration's assertion that Soleimani, the commander of Iran's Quds Force, had been plotting an attack on U.S. persons or interests.

SpaceX successfully launched 60 communications satellites on Monday using a single rocket.

It's the second time in less than a year that Elon Musk's company has made such a launch, marking a dramatic increase in the number of satellites in orbit.

Heavily armed gunmen went on a shooting rampage through the city of Culiacán, the capital of Sinaloa state on Mexico's Pacific coast, battling security forces after authorities attempted to arrest a son of imprisoned drug lord Joaquín "El Chapo" Guzmán.

The gunfire from what appeared to be sniper rifles and truck-mounted machine guns sent residents of the western city scrambling for cover. Burning vehicles littered the streets as the gunmen faced off against the National Guard, army and police.
