In the days before personal computers, before the Internet and the worldwide web connected us to global information, before smartphones connected us to one another, before GPS guided our journeys. Before this technology was a part of everyday life, American astronauts explored new frontiers in space and on the moon. A half century ago, men on board the Mercury, Gemini and Apollo space capsules talked to earth, navigated in space and to the moon and back, and exchanged critical data with mission control. How was this accomplished five decades ago? By the ingenuity and dedication of a company founded in the heartland of America - The Collins Radio Company in Cedar Rapids, Iowa.

"Moon Talk", the second chapter (but first to be completed) of a three-part series, tells the little-known story of the people who designed the space communication systems and how they did it. These systems were technical feats that had never been done before, and played a crucial role in America's race to be first to land a man on the moon.

In 1536, Captain Alcaraza of New Spain met a naked Spaniard who identified himself as Alvar Nunez Cabeza de Vaca. He had been missing for 7 years and was presumed dead, but according to La Relacion, his own written account of events first published in Spain in 1542, something else entirely had occurred.

Scholars agree that he had survived the shipwreck of the 1527 Narvaez Expedition, washing up near what today is Galveston,Texas and had spent 7 years living with the Capoque and Chorruco branches of the Karankawa tribe before traveling all the way from the Atlantic Ocean to the Pacific.

Cabeza de Vaca entered the annals of colonial history as A Savior among Savages: A great explorer who led and taught the natives.

But what if that's not how the story really went?

This 49 minute documentary examines Cabeza de Vaca's time with indigenous North American peoples through the lens of gender.
