William Shatner is getting ready for the trip of a lifetime.

The 90-year-old former Star Trek star is flying to space on Wednesday aboard Jeff Bezos' Blue Origin New Shepard NS-18.

Shatner's historic flight — which will make him the oldest person to ever go to space — comes nearly three months after Bezos, his brother, Mark, and two other passengers flew on the company's first space flight with humans on board.

The event will be live-streamed on Blue Origin's YouTube channel 90 minutes prior to its launch at 9:00 a.m. CDT. Viewers can visit the channel here or watch the video embedded below.

"I'm terrified," he told an audience during a New York Comic-Con panel. "I'm Captain Kirk, and I'm terrified going to space. You know, I'm not really terrified. Yes, I am. It comes and goes like a summer cold."

But he is looking forward to a view few have ever seen before.

"You have three minutes to look into the abscess of space and the beauty of this oasis of Earth, and I was planning on pressing my nose against the window, you know?" he said. "And my only hope was I wouldn't see somebody else looking back."

Shatner's flight comes three months after Bezos' fellow billionaire, Sir Richard Branson, took his first trip to space aboard the VSS Unity spacecraft, Virgin Galactic's first fully crewed flight test.
