Dr. Kathryn Sullivan, the first American woman to walk in space and a veteran of three shuttle missions, talks with Beth about her experience as part of the team that launched, rescued, repaired, and maintained the Hubble Space Telescope on this week\\u2019s episode of the Casual Space Podcast.

The Hubble Space Telescope has revolutionized our understanding of the universe. It has, among many other achievements, revealed thousands of galaxies in what seemed to be empty patches of sky; transformed our knowledge of black holes; found dwarf planets with moons orbiting other stars; and measured precisely how fast the universe is expanding. In\\xa0Handprints on Hubble, retired NASA astronaut Kathryn Sullivan describes her work on the NASA team that made all of this possible. This week, Dr. Sullivan joins Beth to describe how she and other astronauts, engineers, and scientists launched, rescued, repaired, and maintained Hubble, the most productive observatory ever built!

Beth: What invited you to write your book, \\u201cHandprints on Hubble\\u201d and share your story?

Dr. Sullivan: I, like countless engineers on the ground and at mission control, am really proud of everything Hubble has done, and I feel like I have a fingerprint, I have a contribution on everything Hubble has done. The idea of (sharing this) percolated for a long time until a friend at the Smithsonian was trying to get me to consider writing a memoir, and that\\u2019s when the penny dropped-\\xa0 If my story could be the vehicle for telling an overlooked chapter of the Hubble history, and bringing the people who really are the hidden figures of the Hubble story into the foreground so the important work they did got its due. All of the creativity, the engineering, the design work, the imagining in the mid-60\\u2019s a school-bus size telescope and that the astronauts would take care of it! It was astonishing! People don\\u2019t often think of engineers of being imaginative, but Hubble is a really brilliant example of the kind of vision and imagination that describes most of engineering, so if I could use my story to help people understand the importance of this early history of Hubble, that would be worth writing. \\xa0\\xa0\\xa0\\xa0\\xa0\\xa0\\xa0\\xa0\\xa0\\xa0\\xa0\\xa0\\xa0\\xa0\\xa0\\xa0\\xa0\\xa0\\xa0\\xa0\\xa0\\xa0\\xa0\\xa0\\xa0\\xa0\\xa0\\xa0\\xa0\\xa0\\xa0\\xa0 -Kathy Sullivan from the Casual Space Podcast
