  25. OLI/NPOESS Mission Advantages • Transition of Landsat into a truly operational measurement • Extension of the Landsat data record past 2020 • Leverage of proposed NPOESS infrastructure • Benefits derived from combining data from OLI with Visible/Infrared Imager Radiometer Suite (VIIRS) and the Aerosol Polarimeter Sensor (APS): • Large scale processes of change detected by VIIRS can be more closely analyzed by OLI • OLI data can be used to better calibrate VIIRS and validate Environmental Data Records (EDRs) derived from VIIRS data conversely VIIRS spectral bands can be used to atmospherically correct OLI data • Aerosol measurements and corrections can be applied to both sensors • Terra (MODIS sensor) and Landsat 7 results have already demonstrated the potential of combining data

  26. Operational Land Imaging Plan • Responsibilities • NASA -- Procure two OLI sensors, science team • NOAA -- Integration, operations, data relay • USGS -- Image planning, data processing, archive and distribution • Operations concept • USGS provides daily target collection plan • NPOESS • Builds collection into daily mission plan • Receives playback data at SafetyNetTM sites • Data returned to US and forwarded to USGS • USGS • Processes, archives, distributes data

  27. Environmental Satellite ProgramOver Budget, Behind Schedule The U.S. National Polar-orbiting Operational Environmental Satellite System (NPOESS) will exceed its $6.9 billion cost estimate by at least 15 percent, and its planners are now considering cutting instruments and satellites in addition to long delays. “[NPOESS] is so badly broken … we could lose a lot of the climate [components], we could lose instruments,” NPOESS Preparatory Project (NPP) project scientist Jim Gleason told a committee of the National Research Council of the U.S. National Academies at a 25 October meeting. The first NPOESS satellite had been scheduled to launch in 2009, but the launch date has been moved tentatively to 2012 and is likely to slip even further, according to Gleason. However, NPP has suffered its own setbacks, with its launch being moved from October 2006 to April 2008 and now possibly to April 2009. The main problem affecting NPP has been the difficulty in the engineering and construction of [VIIRS]... Because of the engineering problems that still have to be solved, [VIIRS] currently has no scheduled date for completion, according to Gleason. NPOESS chief scientist Stephen A. Mango told the NRC committee, “other snags ... are going to lead to significant delays.” ... One cost-cutting option is to … not include every instrument on every satellite, he said…[O]ne of the three orbits … could be filled by the [MetOp] satellites, although this may cause problems with data continuity, according to Jack Kaye, director of the research and analysis program at NASA. At the NRC committee meeting, Kaye called this option “a giant step backwards.” Canceling the first NPOESS satellite and using NPP to fill that slot—while it still serves as the transition satellite—has also been discussed, according to Gleason. However, NPP carries only four of the 10 instruments planned for NPOESS satellites. No decisions about any of these options have been made at this point, and Mango hopes to have a better understanding about the future of the project after an NPOESS project planning meeting in December. Kaye noted, though, “I think, in the end, we are all going to be forced to make decisions we don’t want to make because of the budget issues.” Excerpts from News article by Sarah Zielinski, Staff Writer, Eos, Vol. 86, No. 45, 8 November 2005

  29. Program Life Cycle Cost Changes “Over the past several years, the NPOESS program has experienced continued schedule delays, cost increases, and technical challenges. The schedule for the launch of the first satellite has been delayed by at least 17 months (until September 2010 at the earliest), and this delay could result in a gap in satellite coverage of at least 3 years if the last satellite in the prior satellite fails to launch. Program life cycle cost estimates have grown from $6.5 billion in 2002 to $8.1 billion in 2004 and are still growing. … bringing the life cycle cost estimate to about $9.7 billion. Technical risks in developing key sensors continue, and could lead to further cost increases and schedule delays.” Source: GAO-06-249T, 16 Nov 2005
