Blue Origin is sending a bunch of women to the final frontier … and TMZ is steaming live as Gayle King, Katy Perry and Lauren Sanchez blast off into space.

One of Jeff Bezos‘ rockets is set to launch at 9:30 AM ET from West Texas … and the girl gang going into orbit also includes NASA rocket scientist Aisha Bowe, civil rights activist Amanda Nguyen, and film producer Kerianne Flynn.

Monday’s mission, dubbed NS-31, is the 11th human flight for Blue Origin … and the 31st overall for the Amazon founder’s space tourism venture.

Jeff has already been to space … and now it’s his fiancée’s turn.

The spaceflight will be relatively short … the women will travel 62 miles above Earth to the Kármán line, the boundary that separates our atmosphere from space … and after a few minutes of weightlessness in orbit, the capsule carrying the women will fall back to Earth.
