Live coverage: Japanese cargo craft departs International Space Station

Riding nearly a million pounds of thrust, NASA astronaut Chris Cassidy and Russian crewmates Anatoly Ivanishin and Ivan Vagner rocketed into orbit April 9 from the Baikonur Cosmodrome en route to the International Space Station.

U.S. spacewalk 94 was slated to have NASA astronauts Mike Fincke and Zena Cardman perform a variety of operations around the orbiting outpost during the roughly 6.5-hour-long event. A new date for the spacewalk hasn’t been announced.

A workhorse Soyuz booster thundered to life and climbed into a dark Kazakh sky Friday, carrying NASA astronaut Scott Kelly and cosmonaut Mikhail Kornienko on a four-orbit voyage to the International Space Station to kick off a marathon 342-day mission, the longest flight ever attempted by an American.
