A mosaic of images taken in January 2012 shows Opportunity's vista north (left) and northeast (right), in an outcrop known as "Greeley Haven," where the rover spent its fifth Martian winter. The image released by NASA is presented in "false color," to make differences in the landscape easier to see.
With the darkest days of the Martian winter now over, NASA took its Opportunity Mars Rover for a drive this week. The rover had been stationary while its solar panels lacked enough sunlight to power its batteries.
The rover's drive Tuesday was a short one: "about 12 feet northwest and downhill," according to NASA. The agency says Opportunity has driven 21.4 miles since it landed on Mars in January of 2004.
Russia's newly reinstalled President Vladimir Putin will be too busy with affairs at home to make a planned visit to the United States this month, where he was to have a high-profile tête-à-tête with President Obama and attend the G8 summit.
In his place, Prime Minister Dmitry Medvedev, who swapped places with Putin in recent elections, will go to the global economic summit.
Chinese activist Chen Guangcheng says his family is being hounded by local authorities in his Shandong, his home province, with his brother and sister-in-law placed under house arrest and his nephew detained.
Chen's flight last month from house arrest and his request for refuge from U.S. diplomats has caused considerable embarrassment for Chinese authorities and threatened to damage U.S.-Sino relations. Since then, Beijing has agreed in a face-saving move to allow the blind, self-taught legal activist and his immediate family to study in the United States.
A pair of powerful explosions ripped through Syria's capital, killing at least 50 people in the deadliest attack in the country's 14-month uprising. Some 170 people were wounded, according to state television.
There was no immediate claim of responsibility, but local TV reports called the attacks "terrorist bombings".
The explosions damaged a military intelligence building and left blood and human remains in the streets, according to The Associated Press.
Syrians appear behind the damaged windshield of a minibus as they inspect the site of a blast in the central Midan district of Damascus last month. A new jihadist organization in Syria claimed responsibility for the attack.
It was Friday, April 27, when a car bomb exploded in the Damascus neighborhood of Midan. Syrian state television showed soldiers and civilians running from the smoke of the explosion under a bridge. Then the camera closed in on streams of blood and body parts.
The Syrian regime's narrative is that the uprising that has gripped the country for more than a year is not a case of people protesting and sometimes fighting for their rights; the official stance is that it's terrorism.
The most challenging cyberattacks these days come from China and target Western firms' trade secrets and intellectual property. But a problem for some is a business opportunity for others: It's boom time for cybersecurity firms that specialize in going after Chinese hackers.
"It's the next big thing," says Richard Stiennon, an industry analyst who specializes in information security firms.
