episode 274: The Shuttle's Achievements for Space Exploration


Guest: Davide Sivolella    Host: Markus Voelter    Shownoter: Andy Joiner

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.
