Aspiring astronaut is American Girl's 2018 Girl of the Year

Popular doll maker American Girl revealed their girl of the year for 2018.

The audience on "Good Morning America" and a group of young girls met 11-year-old aspiring astronaut Luciana Vega.

"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."

American Girl worked with NASA astronaut Dr. Megan McArthur Behnken, former NASA chief scientist Dr. Ellen Stofan, CEO of the U.S. Space and Rocket Center Dr. Deborah Barnhart and manager of strategic alliances at NASA Maureen O'Brien to develop Luciana's background story and product line.

President of American Girl Katy Dickson said Luciana is "a champion of STEM and a natural-born leader."

Luciana's story is told in a three-series book, written by Erin Teagan. It follows her as she wins a scholarship to attend Space Camp in Huntsville, Alabama.

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

After the new doll was revealed, the "GMA" audience and girls were surprised with a doll of their own.
