The first American woman to walk in space recounts her experience within the team that launched, rescued, repaired, and maintained the Hubble Space Telescope. The Hubble Space Telescope has revolutionized our understanding of the universe. It has, among a great many other achievements, revealed thousands of galaxies in what appeared to be unfilled patches of sky; transformed our knowledge of black holes; present dwarf planets with moons orbiting other stars; and measured the way in which fast the universe is about Handprints on Hubble: An Astronaut’s Story of Invention growing. In Handprints on Hubble, retired astronaut Kathryn Sullivan represents her work on the NASA team that made all of this possible. Sullivan, the initial American girl to walk in space, recounts how she and various other astronauts, engineers, and scientists launched, rescued, repaired, and preserved Hubble, the most successful observatory ever constructed. Along the way, Sullivan chronicles her early lifestyle like a ‘Sputnik Baby,’ her way to NASA through oceanography, and her initiation into the space plan as one of ‘thirty-five brand-new men.’ (She was also one of the initial six women to become listed on NASA’s storied astronaut corps.) She describes in stunning details what liftoff feels as though in the spacecraft (it’s like ‘being in an earthquake and a fighter jet at the same time’), shows us the look at from a spacewalk, and recounts the short-term grounding from the shuttle program following the Challenger catastrophe. Sullivan clarifies that ‘maintainability’ was designed into Hubble, and she represents the work of inventing the tools and procedures that made on-orbit maintenance feasible. Because in-flight repair and update was part of the strategy, NASA could fix a serious defect in Hubble’s mirrors?leaving literal and metaphorical ‘handprints on Hubble.’
