Scientist David Dartez, who worked with NASA for over 20 years at the Johnson Space Center in Houston, provided a first-hand history lesson to students at El Morro Elementary last week.
Dartez, the grandfather of an El Morro Elementary student, added an extra dimension to a biography students are studying on Mae Jemison, who was the first African American woman in space, said Jenny Carlson, an instructional aide at the school.
Jemison was aboard the space shuttle Endeavor for eight days in 1992 and
Dartez assisted in its landing, one of the only space shuttles to have landed on a runway, Carlson said.
