Live coverage: SpaceX’s second upgraded “Block 5” booster test-fired in Florida

An atmospheric test model of Sierra Nevada’s Dream Chaser spacecraft, a cargo carrier for the International Space Station that will take off on top of an Atlas 5 rocket and land on a runway, is undergoing braking and steering checks in California ahead of a flight test later this year, the company said Monday.

Three days after launching from Cape Canaveral, SpaceX’s Dragon cargo craft has arrived at the International Space Station with around 5,600 pounds of supplies and experiments. The automated, unpiloted supply ship was snared by the station’s robotic arm at 7:21 a.m. EST (1221 GMT) Saturday.

Two days after launching a Falcon 9 rocket from Florida, SpaceX sent another mission into orbit Sunday from California’s Central Coast with 10 new satellites for Iridium’s voice and data relay network.
