Live coverage: Soyuz crew lands in Kazakhstan

American and Soviet crews were launched today in 1975 for the first handshakes in space between the two superpowers as part of the Apollo-Soyuz Test Project.

Scientists working on a new lightning detection instrument mounted outside the International Space Station said Tuesday they expect little effect on the sensor’s performance from possible contamination from the upper stage of a SpaceX Falcon 9 rocket that launched it into orbit April 2.

SpaceX’s Falcon 9 rocket will go from Cape Canaveral to low Earth orbit in 10 minutes Thursday with a Dragon capsule heading for the International Space Station carrying nearly 6,000 pounds of supplies and experiments.
