Q&A with Andrew Driesman, project manager for Parker Solar Probe (members only)

An early bird rocket launch from the Florida spaceport will take to the skies before dawn Saturday when an Atlas 5 lofts a classified U.S. government satellite.

For the third time in three weeks, SpaceX is preparing to launch a batch of satellites for the company’s Starlink Internet network from Florida’s Space Coast. Liftoff of a Falcon 9 rocket is set for Thursday afternoon from pad 39A at NASA’s Kennedy Space Center in Florida, weather permitting.

An Ariane 5 rocket took off from French Guiana Friday with the heaviest interplanetary science probe ever launched, kicking off a $1.7 billion European Space Agency mission on a decade-long quest to Jupiter’s icy moons in search of environments that could be habitable for life.
