Live coverage: Atlas 5 countdown and launch journal

Scientists eager for answers to long-standing questions about the geology of Mars will get a lift Saturday with the blastoff from California of an Atlas 5 rocket with NASA’s InSight mission, a robotic landing craft that will take the pulse and temperature of the red planet.

SpaceX completed another another launch to add to the company’s Starlink broadband network Thursday. A Falcon 9 rocket lifted off at 8:46 a.m. EDT (1246 GMT) Thursday from pad 39A at NASA’s Kennedy Space Center in Florida.

As viewed from the ITL Causeway at the Cape Canaveral Air Force Station, the United Launch Alliance Atlas 5 rocket departs for space with the EchoStar 19 satellite to delivery Internet connectivity across the U.S.
