Space travel, even low Earth orbit, is probably several years away for most of us; however, students and teachers can research the edge of space by participating in the BalloonSat program. BalloonSat is an offshoot of the Space Grant Consortium's very successful RocketSat program. The Arkansas BalloonSat program consists of teacher-initiated projects that link the use of geospatial technology tools and community resources. This article describes the Arkansas program, which is an excellent example of a collaborative scientific program that makes learning real and meaningful for students.
