Musk Junior High School was a school located on Earth in the 23rd century. Its motto was "vivere est cogitare" ("to live is to think"). The school produced an annual yearbook.
Sylvia Tilly briefly attended the school for six months as a fourteen-year-old, as part of the class of 2247. While there she met May Ahearn, with whom she shared lunches. May remembered it as an “awful school”. (DIS: "New Eden", "Point of Light", "An Obol for Charon")
The school may have been named after Elon Musk. A possible location is San Francisco, since Ahearn was said to originally be from there.
