Video: Change of command aboard International Space Station

Fifty years to the day after Neil Armstrong stepped onto the surface of the moon, a NASA astronaut, an Italian flight engineer and a Russian commander geared up for launch aboard a Soyuz spacecraft Saturday on a six-hour flight to the International Space Station.

In a mission marking the end of an era, NASA astronaut and former virus hunter Kate Rubins, using NASA’s last currently contracted seat on a Russian Soyuz spacecraft, rocketed into orbit Wednesday with two cosmonaut crewmates on a record-setting flight to the International Space Station.

SpaceX sent a cargo capsule with nearly 5,500 pounds of experiments and supplies on a three-day trip to the International Space Station on Sunday, firing the automated spaceship through low-hanging clouds and into orbit from the same launch pad where Apollo astronauts began voyages to the moon.
