Billionaire Richard Branson plans to launch into space Sunday at 10:30 a.m. ET after a 90-minute delay.⁠ ⁠ "Overnight weather delayed the start of flight preparations, but we are on track to fly today with a newly scheduled time," Virgin Galactic tweeted early Sunday.⁠ ⁠ Branson and a crew of two pilots and three mission specialists are set to launch from the air aboard the space plane VSS Unity after being carried to high altitude by the aircraft VMS Eve. ⁠ ⁠ Unity will then use rocket power to fly to the boundary of space. The crew should experience about four minutes of weightlessness before gliding back to Earth. ⁠ ⁠ Virgin Galactic has plans for two more test flights before commercial service is expected to commence in 2022. The company says more than 600 people already have signed up for flights at an estimated $250,000 per person.⁠ ⁠ Tap the link in bio for the latest updates.⁠ ⁠ Photos by Virgin Galactic, @apnews and @gettyimages⁠ ⁠ #VirginGalactic #space #RichardBranson #rocket #travel
