Spacecraft Mechanics and Dynamics

In this video, Li Hutchinson from ARS Technica and astronaut Scott Kelly explore the Kerbal Space Program, a space simulator. They discuss various aspects of space flight, including orbital mechanics, launch sequences, and reentry procedures. Scott Kelly provides insights into real-life space missions, comparing them to the simulation. The video concludes with acknowledgments to contributors and developers.
