Two American astronauts are to step out Saturday on the first of three spacewalks to replace a broken cooling pump at the orbiting International Space Station. The spacewalk is set to begin at 7:10 am (1210 GMT) and last six and a half hours, NASA said. As the ISS spins around the Earth at a speed of five miles (eight kilometers) per second, veteran spacewalker Rick Mastracchio will lead the way, followed by Mike Hopkins, making his first venture outside the global research lab. From the inside, Japanese astronaut Koichi Wakata will operate the station's 50-foot (15-meter) robotic arm, hoisting Mastracchio and hefty equipment from one section of the lab to another.
US Secretary of State John Kerry said he was sending a special envoy to South Sudan to help foster dialogue between opposing factions in the violence-wracked African nation. "Now is the time for South Sudan’s leaders to rein in armed groups under their control, immediately cease attacks on civilians, and end the chain of retributive violence between different ethnic and political groups," Kerry said, as he announced plans to dispatch Ambassador Donald Booth, his special envoy for Sudan and South Sudan, to the region. Kerry added that the decision, which came as battles intensify between rival ethnic groups across South Sudan, followed a phone call he made Thursday to South Sudan's President Salva Kiir. "Last night, I called South Sudanese President Kiir and urged him, as president of all of South Sudan, to protect all South Sudanese citizens and work toward reconciliation," the US top diplomat said.
