Video: Soyuz launcher ready for rollout

Soyuz TMA-15M commander Anton Shkaplerov, flanked on the left by flight engineer Samantha Cristoforetti and on the right by NASA astronaut Terry Virts, are scheduled for liftoff from complex 31 at the Baikonur Cosmodrome in Kazakhstan on Sunday.

Russia launched a Progress resupply mission Tuesday heading for the International Space Station with more than 6,000 pounds of fuel, supplies and experiments to support the lab’s six-person crew, and the automated cargo craft sailed to a smooth link-up with the complex less than six hours later.

The Dragon spaceship poised for launch Tuesday will carry more than 2.5 tons of equipment for the International Space Station’s six-person crew, making the first U.S. supply delivery to the orbiting research complex since the crash of an Antares cargo rocket in October.
