NASA, ESA (European Space Agency) and United Launch Alliance (ULA) have adjusted the launch date of the Solar Orbiter spacecraft to Friday, Feb. 7, from Space Launch Complex 41 on Cape Canaveral Air Force Station in Florida due to the rescheduling of the mission’s Wet Dress Rehearsal. Solar Orbiter will launch aboard a ULA Atlas V rocket from Space Launch Complex 41. The two-hour launch window opens at 11:15 p.m. EST. Solar Orbiter is an international cooperative mission between ESA and NASA. The spacecraft has been developed by Airbus Defence and Space.
