When it debuted to the public on April 9, 1965 (with an exhibition Major League Baseball game featuring the newly-renamed Houston Astros and Mickey Mantle’s New York Yankees), the Astrodome – audaciously dubbed the “Eighth Wonder of the World” by its builders – immediately captured the attention of the sports, entertainment and architectural worlds.  

It was a Texas-sized vision of the future – a seemingly unimaginable feat of engineering, replete with breakthrough innovations such as premium luxury suites, theater-style seating, and the world’s first-ever animated stadium scoreboard.  At the time, it was the biggest-ever indoor space ever made by man – an immense cylinder nearly half-a-mile around and with a flying-saucer-like roofline – that evoked a modern space age that the city of Houston and a reach-the-Moon-obsessed nation envisioned for itself.

Amidst the ambition, not all was perfect: baseball outfielders were initially unable to see fly balls through the stadium’s clear Plexiglas roof panels, and attempts to grow natural grass for its playing surface failed repeatedly (ultimately leading to the development of artificial “AstroTurf”).    

Yet, unquestionably, the arrival of the Astrodome changed the way people viewed sporting events and – putting casual fans at the center of the experience, that would soon become the expected standard for all facets of live communal entertainment.

Penn State University professor Rob Trumpbour (The Eighth Wonder of the World: The Life of Houston’s Iconic Astrodome) joins host Tim Hanlon to discuss the life, impact and ongoing legacy of the Astrodome’s signature role in transforming Houston as a city – and some of the memorable (and not so memorable) pro franchises that called it home during its 43-year run, including the AFL/NFL football Oilers, the NASL soccer Stars and Hurricane, and challenger-league football’s Texans (WFL) and Gamblers (USFL). 

Plus, the backstory of Major League Baseball’s 1962 expansion Houston Colt .45’s – the original catalyst behind the dome’s conception and construction.
