I was sitting in a meeting just now watching as representatives from four different spacecraft operating at Mars were coordinating how they were to work together to transmit data between them. The meeting had broken up, and everybody stood to leave, but lingered to discuss other details of what had to be done to make the next planning cycle go smoothly. I also stood to leave, but paused at the door to marvel at the spectacle. Since my job is focused specifically on trying to get these various projects to work together, the sight brought warm fuzzies to me.
Smart people + working together = great things accomplished.
Sometimes I really love my job.
