Singer Sarah Brightman announced Wednesday that she is postponing her trip to space.

Her $52 million, 10-day trip aboard the International Space Station will be pushed back due to personal family reasons, according to a statement posted to her Facebook page. She had stopped training on April 22, two people familiar with her training schedule tell TIME.

“Since 2012, Sarah has shared her story of a lifelong dream to fly to space. Her international fame as the world’s best-selling soprano has enabled her message to circle the globe, inspiring others to pursue their own dreams,” said Eric Anderson, Co-Founder and Chairman of Space Adventures, Ltd in the statement. “We’ve seen firsthand her dedication to every aspect of her spaceflight training and to date, has passed all of her training and medical tests. We applaud her determination and we’ll continue to support her as she pursues a future spaceflight opportunity.”

Whether what’s being described as a postponement is actually a cancellation is impossible to know right now. Brightman did not even begin her training until Jan. 19, according to Roscosmos, which would have given her less than eight months at best to get ready for a Sept. 1 launch. That’s significantly less time than professional astronauts need to become mission-ready—even without the loss of the last two weeks. It will be up to Roscosmos and Space Adventures to determine if, given all this, they will ever consider it prudent to allow Brightman to fly.

American astronaut Scott Kelly, who is currently in the midst of a yearlong mission aboard the space station, told TIME he was looking forward to Brightman coming aboard.
