## INTRODUCTION

***Dale Schulz***

## PURPOSE OF THE L-11 MONTH READINESS REVIEW

***The purpose of the L-11 month review is to get an assessment by senior project managers and engineers of the likelihood of our meeting our scheduled launch date and to identify any areas that have been overlooked by the EO-1 Project. ***
***Its purpose is not to review the technical design or the funding, which have been subjects of other reviews.  ***

## New Millennium Goals

***New Millennium Goals***

***Revolutionize NASA’s Space and Earth science programs to achieve frequent, less costly missions in the 21st Century by:***
*Flight-validating revolutionary technologies*
*Reducing development times and life-cycle mission costs*
*Enabling highly capable and autonomous spacecraft*
*Promoting Nationwide teaming*

## Program Focus

## What is EO-1?

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

***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*
