A veteran Russian commander, Italian flight engineer and a rookie NASA astronaut lifted off at 1628 GMT (12:28 p.m. EDT) Saturday from the Baikonur Cosmodrome in Kazakhstan, kicking off a six-hour flight to the International Space Station.

Joe Anderson, vice president of business development and operations at Space Logistics LLC, recently discussed the company’s first Mission Extension Vehicle in an interview with Spaceflight Now.
