Atlas/Cygnus pre-launch news conference

Former NASA astronaut Peggy Whitson, with more time in space than any other American, rocketed back into orbit for the fourth time Sunday, riding a SpaceX Falcon 9 launcher from Florida with a fare-paying investor and private pilot, and the first two Saudi Arabian astronauts to fly to the International Space Station.

A SpaceX-owned Dragon cargo craft left the International Space Station on Friday and flew back to Earth for a parachute-assisted splashdown in the Pacific Ocean with a dozen mice and more than 3,000 pounds of experiment specimens and space hardware.

Cameras in various locations at Cape Canaveral and Kennedy Space Center capture the launch of a SpaceX Falcon 9 rocket carrying NASA’s TESS planet-hunting telescope.
