SpaceX has confirmed plans to send two private citizens around the Moon by 2018. The two passengers approached the company privately and have paid “significant deposits,” according to Elon Musk, founder and CEO of SpaceX.

The names of the two citizens people are unreleased. According to Musk they will begin initial training for the trip later this year. Musk declined to announce the real cost of the mission, though admitted that it would be “comparable” the cost of a crewed mission to the International Space Station.

SpaceX hopes to launch the mission during 2018, aboard the Falcon Heavy, a new “super heavy-lift” rocket system that has been developed with the specific intention to carry humans into space.,

A permit from the United Nations will not be necessary, according to Musk, though the trip will need to be licensed by the Federal Aviation Administration.

The trip is estimated to last approximately one week: first, the rocket will skim the surface of the Moon, then go further out into deep space, and finally will loop back to Earth — reaching a distance of approximately 300,000 to 400,000 miles in total.

This will be the first time in 45 years that humans have gone *near* the moon. SpaceX was careful to note that there will no attempted moon landing. Still, this will be the first time in 45 years that humans will have travelled into deep space. SpaceX claims that these travelers will go further into the solar system than any humans have before.
