Communications user terminal prepares for historic moon flyby

In 1969, Apollo 11 astronaut Neil Armstrong stepped onto the moon's surface—a momentous engineering and science feat marked by his iconic words, "That's one small step for a man, one giant leap for mankind." Three years later, Apollo 17 became NASA's final Apollo mission to land humans on the brightest and largest object in our night sky. Since then, no humans have visited the moon or traveled past low Earth orbit (LEO), largely because of shifting politics, funding, and priorities.
