During his maiden voyage to space, “Star Trek” icon William Shatner had an awe-inspiring experience — but it wasn’t necessarily positive.

“So, I went to space,” reads a Variety-published excerpt from Shatner’s new book, “Boldly Go: Reflections on a Life of Awe and Wonder.”

After describing the exhilarating launch procedure and beginning of his zero-gravity excursion, Shatner wrote that when he turned around to look into the void of space, he was shocked by the emptiness he found.
