## What is EO-1?

***What is EO-1?***

***Designed to flight validate breakthrough technologies applicable to Landsat follow-on missions***
***Specifically responsive to the Land Remote Sensing Policy Act of 1992 (Public Law 102-55) wherein NASA is charged to ensure Landsat data continuity through the use of advanced technology:***
***Multispectral Imaging Capability to address traditional Landsat user community***
***Hyperspectral Imaging Capability to address Landsat research-oriented community -- backward compatibility essential***
***Calibration test bed to improve absolute radiometric accuracy***
***Atmospheric correction to compensate for intervening atmosphere***
