On Wednesday, April 29, 2009, Brandi Walker, a fourth grade teacher at San Cayetano School, took two students to the 2009 NES National Student Symposium in Houston, Texas. Angelica Mercado, age 11, and Taylor Wright, age 9, were chosen to present their robotics project at the symposium. Taylor and Angelica had previously been part of the two robotics teams that competed at the Southern California NES NASA JPL Robotics Competition winning first and fourth place respectively. The teacher and students were flown, free of charge, to Houston, Texas. The girls presented their power point in front of a panel of NASA engineers and scientists. The panel asked the students follow up questions when they were done with their presentation. Following this, the students went to activities where they were able to touch rocks from the Moon and engineer machines to shoot water at a target. The afternoon was spent touring Johnson Space Center, where students were able to see the Neutral Buoyancy Lab, while the astronauts were training, life-size mockups of the US and Russian space shuttles and space station, as well as Rocket Park. The following day, the students were taken to Space Center Houston, where they learned about the history of space flight. An education specialist led them through an activity on building rockets. The girls were then able to test their rockets in a game of Rocket Golf with their fellow rocket engineers. After lunch, a space-suit engineer gave a demonstration and seminar on the space suit. The afternoon finished with a panel of NASA employees speaking and answering questions about their careers at NASA. A closing ceremony was held on Friday evening, in which each student was recognized for their participation in the symposium and given a NASA medal and certificate. This was a once in a life-time experience for the students and teacher who were invited to participate in the three days fully funded by NASA.

The NASA Explorer Schools Project establishes a three-year partnership between NASA and school teams to help fourth through ninth grade education communities improve teaching and learning in science, technology, math and engineering. The project works primarily with diverse groups of students who are underrepresented in these disciplines or who are traditionally underserved in rural or urban parts of the country. The project joins educators, students and families in sustained involvement with NASA's research, discoveries and missions.
The opportunity to participate in the symposium was open to all current NASA Explorer Schools. Students were required to complete a research investigation focused on NASA missions or research interests, including science, aerospace, reduced gravity, robotics, plant growth in space, or living and working in space.
