The mission will utilize a brand-new Dragon spacecraft and a Falcon 9 rocket with a reused first stage, previously flown for a Starlink mission, which will aim to land at Cape Canaveral’s Landing Zone 1.
Onboard the ISS, the crew will perform over 60 experiments in human physiology, Earth monitoring, and biological and material sciences, supporting Axiom Space’s vision for private space exploration and a future commercial space station.
SpaceX: A live broadcast will start two hours before launch, accessible via SpaceX’s website, X @SpaceX, or the X TV app.
