NASA is one of the global leaders in scientific astronomic research. They do amazing research on the ISS, they've sent missions into space to explore moons, planets, and different places to get a better understanding and view of them. Finally, they've been an inspiration to many children who aspire to be astronauts and physicists for NASA.
NASA is a socialist bureaucracy that fulfills no constitutionally authorized purpose. If they want to find pots of gold at the end of the rainbow let them seek private investors the way honest people do. Who taught you NASA is a "global leader?"
Was it your government (socialist) "educator?"
Next you are going to tell us the 30 year waste of cash called the "space shuttle" (NOT) was a wonderful use of our cash.
