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.
The SAGE III/ISS Project held a successful Key Decision Point-D (KDP-D) at NASA Headquarters Tuesday, June 9, and was approved to proceed with payload assembly, testing, and launch operations. On Tuesday, June 16, the team conducted a successful peer review of the plans for the upcoming Thermal Vacuum Testing scheduled to begin in July.
