Introduction

• Desire to more fully infuse technology developed
  on EO-1
• Used commercial vehicle to make data from EO-1
  more readily available to public thus increasing
  infusion of EO-1 technology
• EO-1 began as a 1-year technology-demonstration
  mission ending on November 20, 2001
• Technology flight validation was an unqualified
  success
• Satellite is fully operational with three
  imaging sensors
• NASA and USGS entered into a joint partnership
  for an extended mission in December 2001
• Over 5000 scenes collected to date
• High continued interest by DoD, Science, and
  Industry for Hyperion (hyperspectral) and ALI
  (multispectral) image data
• Extended mission is based on cost reimbursable
  model i.e., target is to be self-sustainable
  through product sales

Establishing Commercial Viability

• Summer and Fall of 2001 conducted a series of
  meetings with NASA HQ, Goddard management and
  USGS on how to make EO-1 commercially viable with
  its images
• Had many discussion with variety of additional
  potential partners including commercial
  consortiums, Air Force, Navy NOAA and foreign
  national space agencies
• Came up with a large list of things to do to
  increase the knowledge of EO-1 to the general
  public and how its Hyperion hyperspectral imagery
  and ALI imagery could benefit the public at large
• Publications
• Conferences
• Technology transfer meetings
• Key redirected goals for extended mission were
• Increase number of Data Collection Events (DCEs)
  - Images
• Decrease the cost to collect a DCE
• Increase number of users
• Decrease turnaround time to get DCEs processed
  once taken

  available, successfully reduced cost to
  participate in data infusion process
• Partnership enabled making EO-1 data commercially
  available
• Making the data available to public thus
  increasing infusion of EO-1 technology
• Increased number of users as evidenced by
  previous chart
• Decreased the cost of EO-1 data, making it
  affordable
