SpaceX is targeting Monday, March 31 at 9:46 p.m. ET for Falcon 9’s launch of Fram2 to a polar orbit from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. There are three additional launch opportunities within the approximate 4.5-hour window: 11:20 p.m. ET followed by 12:53 a.m. and 2:26 a.m. on Tuesday, April 1. If needed, backup opportunities are available on Tuesday, April 1 starting at the same time.
A live webcast of this mission will begin about one hour prior to liftoff, which you can watch on X @SpaceX. You can also watch the webcast on the new X TV app.
The Dragon spacecraft supporting this mission previously flew Crew-1 to and from the International Space Station, Inspiration4, the first all-civilian mission to orbit, and Polaris Dawn, the first commercial mission to conduct an extravehicular activity from Dragon.
THE CREW
This will be the sixth flight for the first stage booster supporting this mission, which previously launched Crew-9, RRT-1, Firefly Blue Ghost Mission 1, and two Starlink missions.
Following stage separation, Falcon 9’s first stage will land on the A Shortfall of Gravitas droneship stationed in the Atlantic Ocean.
MISSION OBJECTIVES
During their multi-day mission, Dragon and the crew will explore Earth from a polar orbit and fly over Earth’s polar regions for the first time.
They will also conduct 22 research studies designed to help advance humanity’s capabilities for long-duration space exploration and understanding of human health in space.
This will be the first human spaceflight for Mission Commander Chun Wang, Vehicle Commander Jannicke Mikkelsen, Vehicle Pilot Rabea Rogge, and Mission Specialist and Medical Officer Eric Philips.
Throughout Fram2’s time on-orbit, the crew are planning to take the first x-ray in space, perform exercise studies to maintain muscle and skeletal mass, and grow mushrooms in microgravity.
Additionally, after safely returning to Earth, the crew plans to exit from the Dragon spacecraft without additional medical and operational assistance, helping researchers characterize the ability of astronauts to perform unassisted functional tasks after short and long durations in space.
