In a heavy fog, as is common where Vandenberg AFB lies on the California coast, an Atlas V rocket blasted off this morning and successfully deployed the InSight spacecraft into a trajectory that will take it to Mars for a landing in November.

(See earlier postings here and here about the Insight mission.)

Two MarCO CubeSats, which will demonstrate communications and propulsion technologies for deep space missions with smallsats, were also deployed. First contact attempt will be noon Pacific time.
