This episode is a continuation of the two previous episodes (132, 133) with Davide on the Space Shuttle. Based on his new, second book we talk about the contributions the Space Shuttle made to space exploration in general. These include advances in space suits, the construction of the ISS, satellite servicing, its use as a science platform as well as military operations.

I haven’t listened yet but thanks for the unexpected present under my feedtree, honestly what better way is there to celebrate the holiday than to hide from the family and listen to Markus and Davide discuss the much missed STS.
Merry Christmas Ma/No.
Although in an almost too high orbit for the Shuttle, Hubble was in a too low orbit for the astronomers. The ‘field of view’ was very compromised and passing through a low altitude region of the Van-Allen belts meant it was not usable for a significant part of each orbit.
Fröhliche Weihnachten
Thanks again, Omega Tau just keeps on giving! I can’t get enough of the shuttle, and I’m glad you can’t either. I like all the detail Davide goes into, it’s just great there are guys out there who realize the true value of the Shuttle Program. It’s not just success/failure thing or something that can easily be justified or questioned in the terms of economics. Sometimes some guys just have to push the barriers, no matter what the cost or the unreality of requirements put out by other people. The Space Shuttle did just that. Too bad nothing else followed, and we’re still stuck with simple rockets.
This was another fascinating episode! I have listened to all 3 of the shuttle episodes now, and I bought a copy of Davide’s (first) book. Once I finish that I’ll have to get the second one. I really like hearing all the details, and I feel as if I understand a lot more about the pioneering things the shuttle accomplished.
Thank you so much for these wonderful episodes. There is so much time, effort, and intelligence that you’ve invested and it shows. Keep up the good work.
