Video: Falcon 9 hot fire

Here’s another batch of photos from Saturday’s Falcon 9 launch from Florida’s Space Coast with nearly 6,000 pounds of supplies heading for the International Space Station.

The successful launch and landing by the first stage of a SpaceX Falcon 9 rocket Monday was a significant step toward achieving reusability and, eventually, lowering launch costs, but turning that success into operational reality poses a significant challenge for company founder Elon Musk.

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.
