Live coverage: International Space Station crew lands in Kazakhstan

NASA and Northrop Grumman managers at the Kennedy Space Center decided Tuesday to press ahead with final preparations to launch a NASA scientific research satellite early Wednesday aboard an air-launched Pegasus XL rocket off Florida’s east coast.

A long-delayed Russian science module was transported by train from Moscow to the Baikonur Cosmodrome in Kazakhstan earlier this month for a final series of electrical tests and outfitting before launch to the International Space Station next year.

Russian launch crews stood up a Soyuz rocket Sunday on its launch mount in Kazakhstan for a scheduled liftoff Wednesday with approximately 5,500 pounds of supplies, experiments, fuel and several small satellites to be released by spacewalking cosmonauts at the International Space Station later this year.
