Thursday night's tweet also included a new image of the Big Falcon Rocket, which has long remained under wraps since the company announced it would undergo changes to make its production and deployment more feasible.
It's not the same mission SpaceX founder Elon Musk outlined previous year. The space exploration startup tweeted this morning that it had signed its first passenger up for a trip in the company's BFR rocket.
Musk announced in February 2017 that his company had enlisted two private citizens to fly on a trip around the Moon in 2018.
The names and identities of those two tourists - and how much they meant to pay - were never revealed. We'll find out on Monday if the adventurous soul signed up to the BFR mission is one of the same people that was planning to go on the Falcon Heavy trip.
More details would be made available on Monday, it said.
Ever wondered who owns the moon? Its design was first presented almost a year ago, and the concept boasted a single system that included a booster and a ship that could travel to the moon and Mars.
It would be humanity's first lunar visit since 1972.
The new strategy is to still fly around the moon, but using an even bigger SpaceX rocket still in development that has its own dedicated passenger ship.
During a speech in Australia previous year, Musk said he was hopeful that the BFR would be able to launch and land at last two cargo ships on Mars by 2022.
