A United Launch Alliance Delta 4-Heavy rocket will launch NASA’s Parker Solar Probe. The largest of the Delta 4 family, the Heavy version features three Common Booster Cores mounted together to form a triple-body rocket. The Parker Solar Probe will be the first-ever mission to “touch” the sun. The spacecraft, about the size of a small car, will travel directly into the sun’s atmosphere about 4 million miles from our star’s surface.
