As a National Research Council postdoctoral fellow at the Goddard Institute for Space Studies, New York City, he led the proposal efforts for the Cosmic Background Explorer mission (1974-76), and came to Goddard Space Flight Center to become the Study Scientist (1976-88), Project Scientist (1988-98), and also the Principal Investigator for the Far Infrared Absolute Spectrophotometer (FIRAS) on the Cosmic Background Explorer (COBE).

Dr. Mather and the COBE team showed that the cosmic microwave background radiation has a blackbody spectrum within 50 parts per million (ppm), confirming the Big Bang theory to extraordinary accuracy.
