Pop star Katy Perry and award-winning journalist Gayle King, along with four other accomplished women, are set to launch into space on Monday morning.

Per Good Morning America, Perry and her crew will undergo final training sessions at their rocket’s launch site in Van Horn, Texas, a few days ahead of the flight. The outlet reported that the crew will be “fitted in customized flight suits” on their first day of training, which will also see the group becoming acclimated to their flight capsule.
