331 DAY IN THE LIFE: RISKY AND REWARDING SPACEWALKS—SPACE SHUTTLE MISSION STS-120/ISS-10A CHAPTER 18 that led to flying a boom for shuttle repairs. Additionally, a history of smaller but also critical past solar array deploy issues seasoned the electrical power and EVA teams, readying them in advance for this incredibly daunting challenge. A skilled robotic and EVA crew, strong leadership on board the shuttle and ISS as well as on the ground, and experienced flight controllers in Mission Control were all contributing factors in this success. These factors were not “dumb luck.” NASA and Flight Operations spend a lot of time preparing for the unforeseeable. Even in the best of conditions, factors do not always come together, which is why this team was relieved and exuberant with the outcome. It had been an incredible spacewalk and mission. Cheering had erupted in Mission Control, and the celebration was well earned. However, the next spacewalk by the ISS crew was only a few days away, which meant the team would soon get back to business.
