Live coverage: Soyuz crew lands in Kazakhstan

Seven astronauts and cosmonauts are gearing up for launches April 9 and April 22 to the International Space Station, replacing seven outgoing crew members set to land in Kazakhstan and off the coast of Florida on April 17 and April 28.

Mission leaders Tuesday gave approval for rollout of the United Launch Alliance Atlas 5 rocket to its pad on Wednesday morning, leading to liftoff Thursday evening of a NASA probe to rendezvous with an asteroid and bring a sample back to Earth.

The International Space Station’s first three-man crew moved in on Nov. 2, 2000, 15 years ago Monday, the first of 45 expeditions to date that have logged a decade and a half of continuous human presence in low-Earth orbit.
