Singer Katy Perry is set to blast off to space on Monday on Jeff Bezos' Blue Origin rocket. She's part of an all-women crew, which includes Bezos' bride-to-be Lauren Sánchez, journalist Gayle King, civil rights activist Amanda Nguyen, producer Kerianne Flynn and ex-NASA rocket scientist Aisha Bowe. This will be the first all-female flight to space in over 60 years.
