Sally Ride, Mae Jemison, Nancy Grace Roman and Margaret Hamilton are important names in American space exploration. Jemison is an astronaut, as was Ride. Scientists Roman and Hamilton worked with NASA, the American space agency. Each woman is receiving a very high honor. No, they are not being admitted into a space Hall of Fame. But this honor might be even better: they are becoming Lego action figures. Thanks to the work of a Lego fan and editor at the Massachusetts Institute of Technology, the four women will be represented in miniature toy form starting on November 1. That is when people will be able to purchase the first-ever Women of NASA Lego set.
