Full Blue Origin launch: Bezos completes historic space flight

Billionaire Jeff Bezos's Blue Origin successfully launched their first manned rocket into space, with four aboard including the former Amazon founder. Aboard the company's New Shepard rocket, the crew departed from Van Horn, Texas, on the anniversary of Apollo 11 landing on the moon. Bezos was joined by his brother Mark Bezos, as well as the youngest and oldest people ever to travel to space, 18-year-old Oliver Daemen and 82-year-old Wally Funk.

William Shatner is mentally preparing for his upcoming trip to space with Blue Origin. 

The "Star Trek" actor, 90, is traveling aboard Jeff Bezos' Blue Origin New Shepard NS-18 on Oct. 12 and told audience members during a New York Comic Con panel on Thursday that he's terrified.

"I'm terrified," he confirmed. "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."

"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? And my only hope was I wouldn't see somebody else looking back," Shatner joked. 

The Emmy winner explained he was approached about a space trip over a year ago. Bezos' aerospace company Blue Origin reportedly loved the idea of sending Capt. James T. Kirk on a suborbital flight.

The October trip comes after Blue Origin completed its first successful crewed suborbital spaceflight in July, which flew 66.5 miles above Earth. Bezos was joined on the flight by his brother Mark, 82-year-old aerospace pioneer Wally Funk, and 18-year-old Oliver Daemen, who replaced a mystery auction winner who paid $28 million for a seat

Liftoff for the approximately 11-minute flight on Oct. 12 is currently slated for 9:30 a.m. Eastern Time from Launch Site One in West Texas.

In addition to playing Capt. Kirk on television, Shatner starred in seven "Star Trek" movies, one of which he directed. He also currently serves as the host and executive producer of the History Channel's "The UnXplained," a one-hour, nonfiction series that explores the world’s most fascinating, strange and inexplicable mysteries.
