Musgrave recalled being assigned to Hubble even earlier. “1975, I worked in parallel with other space flights and other work such as the simulation work on Spacelab , and they told me I would be looking after [the Large Space Telescope], identifying every possible problem and coming up with a spacewalking fix.” 8 He was the point of contact in the Astronaut Office for EVA issues, having taken over the role from Rusty Schweickart in 1972. “Of course, in 1975 we didn’t have a telescope, just the idea; we didn’t even have Congressional approval. But it was decided the telescope should be serviceable by a spacewalker, and so the program had a requirement that it would be designed for servicing. So I started straight away, and used my imagination without drawings and without hardware. I started out at home—I had balloons, balloon telescope, balloon spacewalkers and various other things. And as soon as I started to get components, it just evolved from drawings into hardware into components as the structure of the telescope just moved along.” Musgrave explained that it was not as simple as removing a component and sliding in the replacement. The items had to be certified safe for use. “They decided to meet serviceability specifications on some components, and not on others. What I was fighting for was for all components to be ‘friendly’ as opposed to ‘certifiable’; there’s a difference. There were some which were certified and they went very well, [but] there were others that were not even touched and they weren’t friendly for the spacewalker. So that took a huge amount of doing with STS -61 , to do things that had not been designed for servicing.”
