Prior to her upcoming trip to the International Space Station, the acclaimed singer has stepped back into the studio.

On her official Facebook page, Brightman writes, "I had a couple days off from Space training this past weekend and it felt incredible to be back in the Hamburg recording studio working on a few new songs!!"

Brightman, who is part of a three-person crew, reportedly paid $51 million for the chance to travel in space.

"[Others who have traveled in space] have all said it is indescribable," Brightman recently said at a press conference, according to the BBC. "You feel a mixture of laughter and tears. You feel humble but you can see the bigger picture. It's been an unusual path that has taken me to this point and it hasn't been an easy journey. I've found out a lot about myself."

The 54-year-old Brightman will be the first professional singer to visit the orbital outpost.

Sarah Brightman, who had a '70s dance hit on the British pop charts, caught the public's attention in Andrew Lloyd Webber's megahit The Phantom of the Opera when she created the role of opera singer Christine Daae. She also appeared in Lloyd Webber's Aspects of Love before launching an internationally successful concert and recording career. Her duet with tenor Andrea Boccelli, "Time to Say Goodbye," was certified gold in the U.S., was number one on the Billboard charts for more than 30 weeks and sold more than 12 million copies worldwide. Her other solo recordings include, among others, "Symphony," "Encore," "Classics," "Fly," "La Luna," "Timeless," "Eden," "Fly 2," "Dive," "As I Came of Age," "Songs That Got Away" and "Sarah Brightman Sings the Music of Andrew Lloyd Webber."
