Meet American Girl's 2018 girl of the year: Aspiring astronaut Luciana Vega

The president of American Girl called Luciana "a champion of STEM."

"Luciana is our first character that's really immersed in STEM," Rebecca Dekuiper, a designer at American Girl, said in a video about the making of Luciana. "We've had STEM products before, but we really wanted to do a whole character to show girls that STEM is cool."

Katy Dickson, the president of American Girl, called Luciana "a champion of STEM and a natural-born leader," in a statement announcing her as the brand's 2018 girl of the year.

"Luciana is a role model for today’s girls -- empowering them to defy stereotypes, embrace risks and failures, and chart their own course in life -- whatever the goal," Dickson added.

A three-book series about her character, written by Erin Teagan and published by Scholastic, follows Luciana's story as she wins a scholarship to attend Space Camp in Huntsville, Alabama.

The 18-inch doll, featuring brown eyes and dark hair, and full product line including "STEM-inspired outfits and accessories" will launch in stores, online and through American Girl's catalog on Jan. 1.
