Q&A with Mark Sirangelo, leader of Sierra Nevada Space Systems

Watch a replay of Monday’s Falcon 9 launch as seen from the Kennedy Space Center press site, a viewpoint around three miles from pad 39A.

SpaceX’s Falcon 9 rocket successfully launched from Cape Canaveral with a 2.2-ton package of supplies and experiments for the International Space Station on Tuesday, but the booster toppled over after descending to a barge parked in the Atlantic Ocean.

A Northrop Grumman Cygnus supply ship carrying more than 7,200 pounds of provisions and experiments approached the International Space Station two days after its launch from Virginia, moving close enough for capture by the station’s robotic arm at 5:28 a.m. EST (1028 GMT) Monday.
