On Earth Day, 22 April 2015, NASA and the National Science Foundation (NSF) celebrated 20 years of international cooperation and collaboration to engage students, scientists, and teachers in 114 countries in the scientific exploration of Earth’s environments and climate.

The Global Learning and Observations to Benefit the Environment (GLOBE) science and education program, created on Earth Day in 1995, connects students, teachers, and professional and citizen scientists with opportunities to participate in science data collection by conducting real, hands-on science in their local communities.
