I work in the development of optical systems for space science. After dedicating a significant amount of sweat and blood on Chandra, and seeing the dedication of those I worked around and the results coming out of our efforts, it is indeed thrilling to me to be a part of the creation of the instruments that astronomers use to develop the magnificent theories that lead to the understanding of how this small planet that supports our very existence came into being. Sometimes I can't believe how lucky I am to be able to contribute to the production of these incredibly complex instruments that lead to better understanding of our universe. So, thank you for recognizing, in your article, the engineers and scientists behind the understanding that we all are gaining. Letters should be limited to approximately 200 words.
