Photos: Predawn launch of Atlas 5

Less than two weeks after its launch from Cape Canaveral, a new NOAA weather observatory has boosted itself into a circular orbit more than 22,000 miles over the equator, and officials have renamed it GOES-17 ahead of a test series before it enters service later this year.

SpaceX teams at Vandenberg Air Force Base in California are preparing to launch a Falcon 9 rocket into orbit Monday, powered by a reused first stage booster flying on its third mission, a first for the company as engineers continue chasing a long-term goal of re-flying the same rocket on back-to-back days.

Running nearly two months late after technical concerns prevented liftoff last year, a SpaceX Falcon 9 rocket fired into the sky Sunday night from Cape Canaveral with a top secret payload for the U.S. government, the first of some 30 launches on the company’s docket in 2018.
