Video: Atlas 5 rocket launches space station cargo mission

Watch the pre-launch news conference held Monday, March 21 at NASA’s Kennedy Space Center to preview liftoff of the Orbital ATK commercial Cygnus cargo ship aboard a United Launch Alliance Atlas 5 rocket for the International Space Station.

A Russian Soyuz-2.1a rocket rolled out to a launch pad Monday at the Baikonur Cosmodrome in Kazakhstan, ready for the first crewed flight to use the modernized Soyuz booster configuration. Liftoff with two Russian cosmonauts and a veteran NASA astronaut is scheduled Thursday on an expedition to the International Space Station.

Driven by three RS-68A main engines, a United Launch Alliance Delta 4-Heavy rocket lifted off early Sunday from Cape Canaveral carrying NASA’s Parker Solar Probe on a historic mission to study the sun.
