Everything is in the title, I wonder what was approximately the critical dynamic pressure the space shuttle (RIP) could handle, as I am trying to create a simple space flight simulator. I don't need a ...
How are interplanetary trajectories that involve gravity assist maneuvers found? Examples: the MESSENGER spacecraft made flybys of Earth, Venus, and Mercury before getting into orbit the Juno ...
