There are many exchanges that have benefited us from space exploration. One being that we have received knowledge that made us excel in technology along with many other things. Space has gave us the information about zero gravity and how it affects the objects. In January 31st, 1958 the first U.S. Satellite was in action. This has benefited us so much there wouldn't be many things such as TVs, phones, and communication with other countries around the world without satellites. Another exchange that isnt quite directs is all the money these expedition are costing. We have to risk all this in exchange for the befits available on the mission.
