The SpaceX Falcon 9 launch of the Fram2 mission is targeted for Monday from the Kennedy Space Center in Florida.
Liftoff is scheduled for 9:46 p.m. ET.
Three additional opportunities will be available during the 4.5-hour-long launch window: 11:20 p.m. ET, 12:53 a.m. ET, and 2:26 a.m. ET.
This Fram2 mission will send four private astronauts from four different countries into orbit - Chun Wang (Malta), Jannicke Mikkelsen (Norway), Rabea Rogge (Germany), and Eric Phillips (Australia).
The mission will take them into low Earth orbit on a trajectory that will pass over both of Earth's polar regions, a first for human spaceflight.
Previously flown for Crew-1 to and from the International Space Station, the Dragon spacecraft will be used for the multi-day mission, during which 22 research studies will be conducted.
The crew will be conducting the first x-ray in space, performing exercise studies to maintain muscle and skeletal mass, and growing mushrooms in microgravity.
Data collected from these studies will be used to advance humanity's capabilities for long-duration space exploration and understanding of human health in space.
This particular launch will be the sixth flight for the Falcon 9's first stage.
