The National Aeronautics and Space Administration EO-1 satellite was
launched on November 21, 2000 as part of a one-year technology
validation/demonstration mission. The Advanced Land Imager (ALI) instrument
on EO-1 was used to validate and demonstrate technology for the
Landsat Data Continuity Mission (LDCM).
The original EO-1 Mission was successfully completed in November 2001. As
the end of the Mission approached, the remote sensing research and
scientific communities expressed high interest in continued acquisition of
image data from EO-1. Based on this user interest and willingness to assist
in funding continued operations, an agreement was reached between NASA and
the United States Geological Survey to allow continuation of the EO-1
Program as an Extended Mission.
The EO-1 Extended Mission is chartered to collect and distribute
ALI multispectral and
products in response to Data Acquisition Requests (DARs). Under the
Extended Mission provisions, image data acquired by EO-1 are archived and
distributed by the USGS Center for Earth Resources Observation and Science
(EROS) and placed in the public domain.
January 6th, 2017 – EO-1 End of Mission
Effective January 6th, 2017, Earth Observing-1 (EO-1) will no longer accept Data Acquisition Requests (DAR) submissions due to an end in normal imaging operations. All EO-1; ALI and Hyperion data will cease to be populated in the archive by the end of February 2017, however the historical record of EO-1 data will remain available through Earth Explorer (EE) https://earthexplorer.usgs.gov/. EO-1 has been a truly valuable asset to the remote sensing community that has spanned more than 16 years of Earth Observations .
October 1st, 2012 - Registration Changes
Beginning October 1, 2012, all users will be prompted to update their USGS registration profile. Additional fields have been added which will provide the USGS with useful information that may assist in improving the user access experience. After the initial update, users will be prompted every two years to review their information. Thank you in advance for your cooperation in supporting this request.
August 5th, 2009 - Important notice regarding
On June 15, 2009, the USGS Earth Resources Observation and Science (EROS)
Center will begin accepting EO-1 Data Acquisitions Requests (DAR) at no
cost. The DAR forms can be found on the EO-1 Web page and on EarthExplorer.
The EO-1 images not already in the archive will need to be requested by the
customer at no cost using the DAR form. Once the data has been acquired the
customer will be notified by email with image access information.
