Video: Falcon launch replays

SpaceX launched a Falcon 9 rocket Sunday from Cape Canaveral with 143 small satellites, a record number of spacecraft on a single mission, giving a boost to startup space companies and stressing the U.S. military’s tracking network charged with sorting out the locations of all objects in orbit.

The core booster from the Falcon Heavy rocket that launched Thursday from NASA’s Kennedy Space Center in Florida tipped over in rough seas after landing on an offshore drone ship, SpaceX officials said Monday.

The rocket was supposed to launch the SES 9 communication satellite and had already been delayed by fueling problems and a boat that strayed into the launch danger area off shore.
