SwRI-led PUNCH spacecraft have arrived at Vandenberg Space Force Base in California  in preparation for launch, targeted for the end of February. This image illustrates how the four PUNCH satellites will spread out around Earth along the day-night line to create a complete view of the corona and solar wind. Three of the PUNCH satellites will carry SwRI-developed  Wide Field Imagers, and one will carry the Narrow Field Imager.
