Which of these US cities is known for space travel?

As the space race enters its next phase with commercialized travel, Houston is still positioned as the "Space City" for a reason. In the early 1960s, Houston was known as the Bayou City, and its baseball team was called the Colt .45s. But, that changed overnight. The federal government picked Houston for its Manned Spacecraft Center. With it, the baseball team became the Astros, and Houston adopted the nickname, "Space City."
