LDCM History Page
LDCM History • Landsat 7 launch on April 15, 1999 • Release of LDCM Data Buy RFI - June, 1999 • Earth Observing-1 satellite launch - Nov. 21, 2000 – Advanced Land Imager (ALI) aboard • Release of Data Buy Implementation Phase RFP on Jan. 06, 2003 • In Sept. 2003, LDCM Data Buy solicitation cancelled – Vendor failed to take an equity stake required to offer a true public-private partnership – Gov’t accepted all the risk • In December 2003, EOP established the Landsat/Next. View Interagency Working Group (IWG) to study: – Combining LDCM and National Geospatial-Intelligence Agency (NGA) Next. View requirements – USG owned/operated LDCM system – Public/Private partnership for LDCM system – Hosted LDCM payload on USG/Commercial satellites 3/15/2018 Page 5
LDCM History • Memorandum from EOP/OSTP issued on Aug. 13, 2004 on Landsat Data Continuity Strategy – Summarizes outcome of interagency discussions on continuity of Landsat data – Departments of Defense, the Interior, Commerce, and NASA have agreed to: • Transition Landsat measurements to an operational environment on NPOESS • Plan to incorporate a Landsat imager on the first NPOESS spacecraft • Further assess options to mitigate the risks to data continuity prior to the first NPOESSLandsat mission, including a “bridge mission” • Meeting with EOP/OSTP on Nov. 22 -23, 2004 to provide LDCM Status Update – Departments of Defense, the Interior, Commerce, and NASA directed to incorporate OLI onto NPOESS 2130 S/C – No longer continue to pursue “bridge mission” • OLI NPOESS accommodation study conducted between January and May of 2005 – Included GSFC, IPO, NGST, USGS 3/15/2018 Page 6
