The nation's first Hispanic female astronaut is visiting NASA's Marshall Space Flight Center to observe Hispanic Heritage Month.
Ellen Ochoa will speak at the facility in Huntsville on Tuesday morning. The theme is "Hispanics: A legacy of history, a present of action and a future of success."
Ochoa became an astronaut in July 1991 and first flew aboard the space shuttle in 1993. The California native logged nearly 1,000 hours in space on that and three subsequent flights.
Ochoa is currently director of NASA's Johnson Space Center in Houston.
