Musk announced in February 2017 that his company had enlisted two private citizens to fly on a trip around the Moon in 2018.
"SpaceX has signed the world's first private passenger to fly around the Moon aboard our BFR launch vehicle - an important step toward enabling access for everyday people who dream of travelling to space".
However, the company has remained mum about those plans in recent months.More news: Naomi Osaka Slated To Secure History-Making Bag With Adidas
SpaceX declined an AFP request for more details, but said further information would follow Monday at an event lasting from 5:30 pm to 7:00 pm (0030 GMT to 0200 GMT).
The BFR, which Elon Musk said can carry up to 100 people when it was first touted past year, will fly around the moon as part of the personal trip. However the passengers were never named and the flight has yet to materialize.
It would be humanity's first lunar visit since 1972. The original plan called for two paying passengers to fly around the moon this year, using a Falcon Heavy rocket and a Dragon crew capsule.

"All our resources will turn toward building BFR", Musk said a year ago, reported the Verge.
SpaceX has established its bona fides in the aerospace business by transporting supplies to the International Space Station and by completing the tricky maneuver of recovering rockets after launch so that they can be reused.More news: Paul Manafort may have struck a deal with Robert Mueller
