Reusable in nature, the Crew Dragon will offer savings to NASA.[27] SpaceX conducted a test of an empty Crew Dragon to ISS in early 2019, and later in the year, they plan to launch a crewed Dragon which will send U.S. astronauts to the ISS for the first time since the retirement of the Space Shuttle in 2011.[28][29] In February 2017, SpaceX announced that two would-be space tourists had put down "significant deposits" for a mission which would see the two tourists fly on board a Dragon capsule around the Moon and back again.
