Exploration of the Moon and Asteroids by Secondary Students (ExMASS)

The ExMASS program has ended. Program resources will remain accessible on this website (below). Thank you to all the students, teachers, and scientists who participated in this successful program.

ExMASS: A viable model for authentic student-scientist research p​a​r​t​n​e​r​s​h​i​p​s


  • Attitudes Toward Science survey developed during the program is valid and reliable.
  • Survey measured statistically significant increases in student attitudes toward science.
  • ExMASS is a viable model for authentic scientific research by high school students.

The Exploration of the Moon and Asteroids by Secondary Students (ExMASS) program is managed by the Center for Lunar Science and Exploration (CLSE), one of nine teams with the NASA Solar System Exploration Research Virtual Institute (SSERVI). ExMASS is an academic year-long, national standards-based lunar/asteroid research program that envelops students in the process of science. Working alongside their teachers and a scientist advisor, students undertake authentic, open-inquiry research projects that engage them in the process of science. At the end of the year, student research is reviewed by a panel of scientists. The top four teams present their research to this panel of scientists, competing for a chance to present their work at the Exploration Science Forum held at the NASA Ames Research Center in the summer.
