Stratospheric Aerosol and Gas Experiment (SAGE)

The Stratospheric Aerosol and Gas Experiment, SAGE, is a series of instruments designed by NASA to observe stratospheric ozone, aerosols, and water vapor from space. In the mid-1980s, scientists realized there was a problem with Earth’s protective coat of ozone...it was thinning. The SAGE family of instruments was pivotal in making accurate measurements of the amount of ozone loss in Earth’s atmosphere and helped leaders around the world institute an international treaty banning products containing harmful chemicals that destroy stratospheric ozone. SAGE is a key part of NASA’s mission to provide crucial, long-term measurements that will help humans better understand and care for Earth’s atmosphere.

SAGE III/ISS to Study Earth’s Ozone Layer from the Space Station

The SAGE III/ISS instrument has been undergoing rigorous testing and review leading up to the scheduled 2016 launch. Flight components are being put through a battery of environmental tests to ensure that they will perform as planned while withstanding the rigors of launch and the harsh environment of space.
