Ladies and Gentlemen,
it is time to think beyond the humble limits of our beautiful but small planet in search for new supply chain possibilities.
We owe the following chart to the MIT. It illustrates an Interplanetary Supply Chain Network for Space Exploration.
The red circles mark planetary surface nodes, orbital nodes and Lagrangian nodes. These nodes are connected via arcs, representing launch, in-space trajectories as well as entry-descent-and-landing operations. Elements such as space ships are traveling on these arcs, containing human crews, robotic agents, propellant, collected samples as well as various supply items.
