Solar Orbiter (Sol0) Atlas 5 Launch
A United Launch Alliance Atlas 5 rocket will launch the Solar Orbiter spacecraft for NASA and the European Space Agency. Built by Airbus Defense and Space, Solar Orbiter, or SolO, will travel inside the orbit of Mercury to study how the sun creates and controls the heliosphere, the vast bubble of charged particles blown by the solar wind into the interstellar medium. The rocket will fly in the 411 vehicle configuration with a four-meter fairing, one solid rocket booster and a single-engine Centaur upper stage.
Launch time: 0427 GMT on 6th (11:27 p.m. EST on 5th)
