Katy Perry will be taking off on the first all-female space mission since 1963 at 12:30am (Tuesday, AEST) alongside journalists Gayle King and Lauren Sanchez.
The space mission is the latest flight on Jeff Bezos’ Blue Origin New Shepard new vehicle, which was created for commercial space flights.
Tickets for a Blue Origin flight can cost millions. Other celebrities have taken voyages with Blue Origin, including Dude Perfect’s Coby Cotton, whose seat cost US$1.25 million, according to Quartz.
This flight comes as Jeff Bezos attempts to compete with Elon Musk’s Space X commercial space monopoly.
In an interview with the Associated Press, Perry said she has always wanted to go to space and has been training for the journey.
“I’ve always been interested in astrophysics and interested in astronomy and astrology and the stars,” she said.
“I am talking to myself every day and going, ‘You’re brave, you’re bold, you are doing this for the next generation to inspire so many different people', but especially young girls to go, ‘I’ll go to space in the future.’ No limitations.”
Perry has also posted a TikTok sharing her thoughts one day out from the voyage.
Others on the flight will include Amanda Ngutyen, a civil rights activist who will be the first Vietnamese woman to fly to space, film producer Karianne Flynn, and entrepreneur and former NASA rocket scientist Aisha Bowe.
The flight is expected to take just 11 minutes and will fly around 62 miles (99.7 kilometres) past the Kármán line, which is the internationally recognised boundary of space.
Blue Origin will provide live coverage and livestream of the launch on social media and its website, with the coverage beginning 30 minutes before launch.
