Book excerpt: "NOAA established the JPSS program in 2010 to replace aging polar satellites and provide critical environmental data used in forecasting the weather. However, the potential exists for a gap in satellite data if the current satellite fails before the next one is operational. Because of this risk and the potential impact of a gap on the health and safety of the U.S. population and economy, GAO added this issue to its High Risk list in 2013, and it remained on the list in 2015. GAO was asked to review the JPSS program. GAO’s objectives were to (1) evaluate progress on the program, (2) assess efforts to implement appropriate information security protections for polar satellite data, (3) evaluate efforts to assess and mitigate a potential near-term gap in polar satellite data, and (4) assess agency plans for a follow-on polar satellite program. To do so, GAO analyzed program status reports, milestone reviews, and risk data; assessed security policies and procedures against agency policy and best practices; examined contingency plans and actions, as well as planning documents for future satellites; and interviewed experts as well as agency and contractor officials. GAO recommends that NOAA take steps to address deficiencies in its information security program and complete key program planning actions needed to justify and move forward on a follow-on polar satellite program. NOAA concurred with GAO’s recommendations and identified steps it is taking to address them."--Highlights page.

This book was released on 2013-08-13 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solar irradiance is a vital source of energy input for the Earth's climate system and its variability has the potential to mitigate or exacerbate a human-created climate. Maintaining an unbroken record of Total Solar Irradiance (TSI) is critical in resolving ongoing debates regarding the potential role of solar variability in influencing Earth's climate. Space-borne instruments have acquired TSI data since 1978. Currently, the best calibrated and lowest noise source of TSI measurements is the Total Irradiance Monitor (TIM) onboard NASA's Solar Radiation and Climate Experiment (SORCE). These TIM-era data are of higher quality than the older data in the full record. Thus, the TSI climate data record (CDR) has two components. There is the shorter, but more accurate record of the TIM era and the full (33+ year) space-based TSI measurement record. Both are important and require preservation. Review of NOAA Working Group Report on Maintaining the Continuation of Long-Term Satellite Total Irradiance Observations evaluates NOAA's plan for mitigating the loss of total solar irradiance measurements from space, given the likelihood of losing this capacity from instruments currently on the SORCE satellite in coming years and the short term/experimental nature of the currently identified method of filling the data gap. This report evaluates NOAA's plan for mitigating the gap in total solar irradiance data.

This book was released on 2013-08 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Department of Commerce's National Oceanic and Atmospheric Administration (NOAA), with the aid of the National Aeronautics and Space Administration (NASA), is to procure the next generation of geostationary operational environmental satellites, called Geostationary Operational Environmental Satellite-R (GOES-R) series. The GOES-R series is to replace the current series of satellites, which will likely begin to reach the end of their useful lives in approximately 2015. This new series is considered critical to the United States' ability to maintain the continuity of data required for weather forecasting through the year 2028. GAO was asked to (1) determine the status of the GOES-R acquisition; (2) evaluate whether NOAA has established adequate contingency plans in the event of delays; and (3) assess NOAA's efforts to identify GOES data users, prioritize their data needs, and communicate with them about the program's status. To do so, GAO analyzed contractor and program data and interviewed officials from NOAA, NASA, and other federal agencies that rely on GOES data.

Book excerpt: " NOAA established the JPSS program in 2010 to replace aging polar satellites and provide critical environmental data used in forecasting weather and measuring variations in climate. However, program officials anticipate a gap in satellite data between the time that the S-NPP satellite reaches the end of its life and the JPSS-1 satellite becomes operational (see graphic). Given the criticality of satellite data to weather forecasts, the likelihood of a significant satellite data gap, and the potential impact of a gap on the health and safety of the U.S. population and economy, GAO added this issue to its High Risk List in 2013. GAO was asked to review the JPSS program because of the importance of polar satellite data. GAO's objectives were to (1) evaluate NOAA's progress in sustaining the continuity of NOAA's polar-orbiting satellite system through S-NPP and JPSS satellites; (2) evaluate the quality of NOAA's program schedule; and (3) assess NOAA's plans to address potential gaps in polar satellite data. To do so, GAO analyzed program management status reports, milestone reviews, and schedule data; examined polar gap contingency plans; and interviewed agency and contractor officials. "

Available in PDF, EPUB and Kindle. Book excerpt: This unique collection of government documents provides comprehensive coverage of all aspects of current and planned American weather satellites, with material from NOAA, NASA, and independent reviews of the troubled replacement program. Contents: Launch Delayed - NOAA Faces Key Decisions on Timing of Future Satellites * Improvements Needed in NOAA's Mitigation Strategies as It Prepares for Potential Satellite Coverage Gaps * Polar Weather Satellites - NOAA Needs To Prepare for Near-term Data Gaps * Geostationary Weather Satellites - Launch Date Nears, but Remaining Schedule Risks Need to be Addressed * History of the NOAA Satellite Program * NOAA Satellite Conference 2015 Summary Report * NOAA-N Satellite, POES Program * NOAA Response - A Review of NOAA's Satellite Program: A Way Forward * NOAA's GOES R - Next Generation Satellite * NOAA Knows...Earth-Observing Satellites * Options for Modernizing Military Weather Satellites * Bridging the Gap: America's Weather Satellites and Weather Forecasting The National Oceanic and Atmospheric Administration's (NOAA) $10.9 billion Geostationary Operational Environmental Satellite-R (GOES-R) program recently delayed the planned launch of the first satellite in the new series from March 2016 to October 2016. Based on its ongoing work, GAO found that the decision to delay the launch was due to poor schedule performance over the last few years (losing more than 10 days a month on average), recent technical issues with key components, and little schedule margin as the program entered integration testing. The October 2016 launch date may also be delayed if additional technical challenges arise or if schedule performance remains poor. NOAA recently changed assumptions about the expected lifespan of existing GOES satellites from 7 to 10 years based on the longevity of prior satellites. However, the analysis supporting this change is over 10 years old. Even with this extension, NOAA may fall short of its policy of having 2 operational satellites and 1 backup satellite in orbit. The agency faces an 11 month gap in backup coverage until GOES-R is operational, during which time there would be only 2 operational satellites. Any further delays in the GOES-R launch date could exacerbate that gap. NOAA is now facing important decisions on when to launch the remaining satellites in the GOES-R series to maximize satellite coverage while minimizing development and storage costs. Based on its ongoing work, GAO found that NOAA's $11.3 billion Joint Polar Satellite System (JPSS) program is making progress toward the planned launch of the JPSS-1 satellite in March 2017. However, the program has experienced technical issues that have affected internal schedule deadlines, such as an issue with debris in an instrument's subsystem that delayed its delivery by approximately 8 months, and faces key risks in the remainder of development. NOAA is also facing the risk of a potential near-term gap in polar data prior to the launch of the JPSS-1 satellite. Similar to the decision on the GOES satellites, in April 2015, NOAA revised its assumptions about the expected life of the satellite that is currently in-orbit by adding up to 4 years, which would reduce the chance of a near-term gap. However, risks to the performance and health of the on-orbit satellite, and to development of the JPSS-2 satellite could increase the risk of a gap. Also, NOAA faces key decisions on timing the development and launch of the remaining JPSS satellites to ensure satellite continuity while balancing the possibility that satellites could last much longer than anticipated.

This book was released on 2000-05-12 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Remote observations of Earth from space serve an extraordinarily broad range of purposes, resulting in extraordinary demands on those at the National Aeronautics and Space Administration (NASA), the National Oceanic and Atmospheric Administration (NOAA), and elsewhere who must decide how to execute them. In research, Earth observations promise large volumes of data to a variety of disciplines with differing needs for measurement type, simultaneity, continuity, and long-term instrument stability. Operational needs, such as weather forecasting, add a distinct set of requirements for continual and highly reliable monitoring of global conditions. The Role of Small Satellites in NASA and NOAA Earth Observation Programs confronts these diverse requirements and assesses how they might be met by small satellites. In the past, the preferred architecture for most NASA and NOAA missions was a single large spacecraft platform containing a sophisticated suite of instruments. But the recognition in other areas of space research that cost-effectiveness, flexibility, and robustness may be enhanced by using small spacecraft has raised questions about this philosophy of Earth observation. For example, NASA has already abandoned its original plan for a follow-on series of major platforms in its Earth Observing System. This study finds that small spacecraft can play an important role in Earth observation programs, providing to this field some of the expected benefits that are normally associated with such programs, such as rapid development and lower individual mission cost. It also identifies some of the programmatic and technical challenges associated with a mission composed of small spacecraft, as well as reasons why more traditional, larger platforms might still be preferred. The reasonable conclusion is that a systems-level examination is required to determine the optimum architecture for a given scientific and/or operational objective. The implied new challenge is for NASA and NOAA to find intra- and interagency planning mechanisms that can achieve the most appropriate and cost-effective balance among their various requirements.

Available in PDF, EPUB and Kindle. Book excerpt: In the 8 years since a contract was awarded, the National Polar-Orbiting Operational Environ. Satellite System (NPOESS) -- a tri-agency program managed by NOAA, DoD, and NASA -- has experienced escalating costs, schedule delays, and ineffective interagency mgmt. The launch date for a demo. satellite has been delayed by 5 years and the cost estimate for the program has more than doubled. In Feb. 2010, NPOESS was disbanded, and, instead, the agencies have undertaken separate acquisitions. This report: (1) assessed efforts to establish separate satellite programs; (2) evaluated the status and risks of the NPOESS components still under development; and (3) evaluated the implications of using the demo. satellite's data operationally.
