"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".
Elon Musk's rocket and spaceship company has not named the person who will take part in this historic trip. Plans for that flight were eventually delayed; it's unclear if one of the two passengers from that flight will be taking the trip on the BFR.
Musk responded to questions from Twitter users following the announcement, saying that the rocket is still in development and has been "intentionally" created to resemble one seen in a classic comic book series, "The Adventures of Tintin".
More details would be made available on Monday, it said.
The big reveal on who it is - and when the flight to the moon will be - will be announced Monday at the company's headquarters in Hawthorne, California.
"We've been approached to do a crewed mission beyond the moon from some private individuals", he said at the time.
It would be humanity's first lunar visit since 1972. "And we believe we can do this with the revenue we receive from launching satellites and servicing the space station".
Earlier this year, Musk said the company would be able to focus its investment on the BFR, following the successful launch of the Falcon Heavy.
