The 11th flight test of SpaceX's Starship megarocket is on the launch pad and preparing to launch Monday evening. The launch window opens at 7:15 p.m. ET. The launch is the fifth flight test in 2025. The spacecraft is expected to take astronauts to the moon and eventually Mars.

Solid Rocket Motors allow extended range and customized thrust profiles with the same propellant and the same size rocket motor.

In preparation for future returns to Starbase, the ship on Flight 11 will perform a "dynamic banking maneuver" and test subsonic guidance algorithms prior to its final engine burn to brake for splashdown. If all goes according to plan, the flight will end with a controlled water landing in the Indian Ocean approximately 66 minutes after liftoff.

SpaceX launched its 11th test flight of the powerful Starship and Super Heavy rocket from its Texas site Starbase on Monday as it moved ahead in its goals to achieve an operational rocket that could eventually launch from Florida.
