How have spacecraft disgusting a text contribute to the discoveries made in space?

They see things we can't from Earth.

Explanation:

They have discovered solar flares, giant waves, comets, global circulation, coronal mass injections, polar coronal holes, etc. We cannot see these things from earth, so when we create spacecrafts and send them to space, with or without people in them, they study what they see and what it is.
