The four notable NASA pioneers honored in the set are: computer scientist Margaret Hamilton, who played a major role in coding the flight software for the Apollo missions; famed first woman in space, Sally Ride; the "Mother of Hubble" Nancy Grace Roman; and astronaut and physician Mae Jemison, the first African American woman in space. (The original proposal also included Katherine Johnson, the mathematician at the center of Hidden Figures, but the company was reportedly not able to secure the needed approvals to feature her in the final set.)
The minifigures were created with set pieces like Hamilton’s stacks of code, scientific instruments, a microscale Hubble Space Telescope, a space shuttle, and more. The long-awaited 231-piece set officially went on sale on November 1
