Live coverage: Space station crew investigating slow pressure leak

SpaceX engineers are preparing to mount a Falcon 9 rocket at Kennedy Space Center’s historic launch pad 39A for the first time this week as the company declares the modified facility ready to support a new era of commercial space missions.

SpaceX’s first Crew Dragon spacecraft, a capsule designed to eventually carry astronauts on treks to the International Space Station, has arrived at Cape Canaveral to begin preparations for launch on an unpiloted test flight later this year.

A commercial supply ship owned and operated by SpaceX arrived at the International Space Station on Saturday, delivering a pair of NASA experiments to demonstrate satellite refueling techniques and monitor changes in Earth’s forests, along with a special holiday menu of turkey, candied yams, cranberry sauce and shortbread cookies.
