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.

ORR Success!

The SAGE III/ISS Project successfully completed its Operational Readiness Review on June 8, 2016 at NASA Langley Research Center. Members of the NASA Marshall Space Flight Center operations team, the NASA Johnson Space Center ISS Program team, and the European Space Agency participated in the review providing status on operations readiness. The review was also attended by Nand Topiwala, Program Executive, NASA HQ, and Otilia Rodriguez-Alvarez, Mission Manager, Earth Systematic Mission Program Office, NASA GSFC. The Standing Review Board (SRB) complimented the team’s preparedness, openness in sharing information, and significant progress in working all safety items and requirements with ISS. No Requests For Action were issued. A checkpoint is scheduled in August to confirm closure of all paperwork in preparation for the final reviews for launch in November 2016.
