Just found my new favorite website. Casey Handmer writes well-reasoned, scientific essays about space travel and how it is likely to happen. For example, this essay on using the SpaceX Starship as the basis for a Moon colony is fact-filled, annotated, illustrated and compelling. Every science enthusiast and science fiction writer should bookmark this website as favorite. Topics ranging from extraterrestrial shelter, to propulsion, to space suits and orbital mechanics are covered. Love it!
