description SAGE III on ISS Overview
SAGE III on ISS is a NASA instrument installed on the International Space Station in 2017 to continue long-term measurements of atmospheric gases. As the third mission in the Stratospheric Aerosol and Gas Experiment series, it monitors stratospheric ozone, aerosols, and water vapor using solar and lunar occultation techniques. The instrument operates from the station's orbit, providing critical data for understanding global climate change and tracking the recovery of the ozone layer.
help SAGE III on ISS FAQ
What does the SAGE III instrument measure from the International Space Station?
Installed on the ISS in 2017, SAGE III is designed to take long-term measurements of stratospheric ozone, aerosols, and water vapor. It uses a technique called occultation to scan the atmosphere as the sun rises and sets.
When was the SAGE III instrument installed on the International Space Station?
The NASA instrument was successfully installed on the exterior of the ISS in 2017. It was robotically attached to continue decades of critical atmospheric data collection.
What series of missions does SAGE III belong to?
It is the third mission in the Stratospheric Aerosol and Gas Experiment (SAGE) series. The program has provided vital data regarding the Earth's ozone layer since its inception.
Why was SAGE III sent to the International Space Station?
The ISS provides an ideal, stable orbital platform at the perfect altitude to monitor Earth's atmosphere. Placing SAGE III there allowed NASA to continue the satellite's legacy of tracking ozone recovery from space.
