Live coverage: Vega rocket launches with LISA Pathfinder

An Orbital ATK Minotaur 4 rocket partially powered by modified motors from a Cold War-era nuclear missile lifted off early Saturday from Cape Canaveral with a small U.S. military satellite to help track other objects in space. The solid-fueled launcher took off at 2:04 a.m. EDT (0604 GMT) after a weather delay.

A day before blastoff with two Intelsat communications satellites, an Ariane 5 rocket rolled into position on its launch pad in French Guiana on Tuesday behind a 540-horsepower Titan truck, and these close-up snapshots show technicians preparing for the journey.

A first look at the red planet from the ExoMars Trace Gas Orbiter, now in its second month at Mars, gave scientists a sample of the three-dimensional imagery and detailed atmospheric measurements expected over the spacecraft’s five-year mission.
