American singing sensation Katy Perry among five all-women crew members to fly into space in Blue Origin rocket today

Blue Origin is a company owned by Amazon boss Jeff Bezos.

Katy's co-passengers for the joyride in space will also include Bezos's fiancée Lauren Sánchez and CBS presenter Gayle King, former NASA rocket scientist Aisha Bowe, civil rights activist Amanda Nguyen, and film producer Kerianne Flynn.

"The New Shepard launch window opens at 8:30 a.m. CDT / 13:30 UTC," the company said in a statement.

The New Shepard rocket is due to lift off from the West Texas launch site.

The flight is expected to last for 11 minutes.

The passengers will be taken more than 100km (62 miles) above Earth.

They are scheduled to cross the internationally recognised boundary of space.

The autonomous spacecraft will not require a pilot.

The crew members will not operate the spacecraft manually.

The capsule will return to Earth with a parachute-assisted soft landing, while the rocket booster will land itself around two miles away from the launch site, reported BBC.

Dreamt of going to space for 15 years, says Perry

In her Instagram page, Katy Perry said she had been planning to travel to space for the past 15 years.

She wrote, "I’ve dreamt of going to space for 15 years and tomorrow that dream becomes a reality."

"The Taking Up Space Crew launches tomorrow morning at 7am CT and I am SO honored to be alongside 5 other incredible and inspiring women as we become the first ever all female flight space crew!" she said.

This is the first all-female crew that will travel to space in the past 60 years.

Soviet-era cosmonaut Valentina Tereshkova was the first woman to travel to space in 1963.
