New Shepard's 18th mission, NS-18, is set to lift off on Wednesday, October 13, carrying four astronauts: Dr. Chris Boshuizen, Glen de Vries, Audrey Powers, and William Shatner.
"Due to forecasted winds on Tuesday, October 12, Blue Origin's mission operations team has made the decision to delay the launch of NS-18 and is now targeting Wednesday, October 13," a spokeswoman said in a statement.
Coverage of the flight is set to begin at 8:30 am (1330 GMT) on Wednesday and you can watch it below:
Shatner, 90, will be the oldest person ever to go to space.
His trip will take him and the NS-18 rocket crew just beyond the Karman line, 62 miles (100 kilometers) high, where they will experience four minutes of weightlessness and gaze out at the curvature of the planet.
Blue Origin's decision to invite one of the most recognizable galaxy-faring characters from science fiction for its second crewed flight has helped maintain excitement around the nascent space tourism sector.
For fans, the 10-minute hop from a West Texas base back to Earth will be a fitting coda for a pop culture phenomenon that inspired generations of astronauts.
