 I started working for NASA in 1974, right straight out of graduate school, in New York City, where we have a small laboratory called the Goddard Institute for Space Studies, and I was going to do radio astronomy, and I did a little bit of that. And then NASA said we want proposals for new satellite missions. That was 1974, just five years after the Apollo landed on the moon. And so I said, well, my thesis project failed, but it should have been done in outer space. So we proposed a satellite to continue that work, which was to measure the cosmic microwave background radiation, which is the heat radiation of the early universe. So that became a real flight project. Satellite was launched called the Cosmic Background Explorer, or COBE, and that measured the primeval heat really, really well and earned a Nobel Prize in 2006.
