I glanced at the path we had made across the Mare Serenitatis . The Latin translated as "the Sea of Serenity." It was well named because, as far as the eye could see in every direction, there was a smooth layer of pumice that resembled the surface of a calm sea. Scattered across the quiet sea of virgin Moon dust were occasional islands of rock that jutted abruptly toward the infinity of stars above. Considering everything, our surroundings conveyed a sense of serenity like none I had ever felt.
