Retired NASA astronaut Michael López-Alegría will command the  Ax-3 mission, which Axiom Space Inc., a Houston-based company, operates. 

López-Alegría will be joined by Italian co-pilot Walter Villadei, European Space Agency astronaut Marcus Wandt of Sweden, and Turkey's Alper Gezeravci.

SpaceX plans to open the "instantaneous launch window" at 1649 ET for Ax-3 astronauts that will launch from Pad 39A at NASA's Kennedy Space Center.
