  5. PDR Preparation Preparation for SDO PDRs planned and guided by: • SDO Checklist for Subsystem PDRs 9/17/03: • Distributed a checklist to guide the various subsystem PDRs & Peer reviews. • “Demonstrate that a sufficiently mature subsystem definition, design, & development/verification process is in place to allow the subsystem development effort to move out of the preliminary design phase & into the final design phase.” • SDO Guideline for Mission PDR preparations 10/3/03 • Distributed a guideline considering the PDR requirements of GSFC Code 300, Code S Handbook, Confirmation Review Requirements, NASA Systems Engineering Handbook, SDO MAR, & SEMP. • “The Preliminary Design Review demonstrates that the “right system” has been chosen by: 1) A preliminary design exists that is compliant with the requirements & operations concept; 2) The cost, schedule, & risk are consistent with project resources & constraints; 3) Justifies that the maturity of the design effort is appropriate to support proceeding with detailed design activities.”

  6. LWS IRT Terms of Reference Phase B to C Confirmation Assessment (CA) • The CA will cover all elements of the life cycle of the mission including the mission definition, design, development, & operations phases. The program documentation will also be provided in draft form if the CA occurs before the SDO Project transition to implementation due to immaturity of the LWS program. For each element, the assessment will stress identifying & qualifying the risks for items that include but are not limited to: TECHNICAL (Road Map)

  11. Living With a Star (LWS) Program • How and why does the Sun vary? • How does the Earth respond? • What are the impacts to humanity? Living With a Star Science Objectives • SDO is the 1st mission under the Living With a Star (LWS) Program. • LWS is part of NASA’s Sun-Earth Connection (SEC) theme (Space Science Enterprise/Code S). • LWS utilizes a systems approach (inter-related missions) to develop the scientific understanding to address those aspects of the connected Sun-Earth system that directly affect life and society. • Primary goal of the SDO mission is to understand, driving towards a predictive capability, the nature and source of the solar variations that affect life and society by determining. Current LWS Missions

  12. Mission/Project Overview • Received (12/01) NASA HQ Code S approval for GSFC in-house implementation. • Investigations selected thru Announcement of Opportunity process. • Mission development & management at GSFC. • S/C build & Observatory integration/testing will be performed in-house at GSFC. • GSFC responsible for Gnd Sys. development/management & Mission Operations. • Instrument contracts managed by GSFC – Principal Investigators responsible for development of their Instrument & Science Operations Center. • April 2008 EELV launch from KSC into GEO-Transfer Orbit (GTO), circularize to GEO-Sync Orbit, inclined 28.5 degrees with semiannual eclipse seasons. • Spacecraft: robust/redundant, 3-axis stabilized, solar-tracking with low jitter, continuous high rate data (130 Mbps), & 5 year life. • Single ground station with distributed Science Operation Centers. • Non-Science driven level 1 requirements: • 3200 kg SDO Observatory mass allocation with remaining LV lift capability reserved for potential secondary payload. • GTO insertion transfer orbit with a minimum perigee of 300 km for possible secondary GTO payload options.

  13. SDO Driving Requirements & Challenges • High data volume, coupled with tight requirements on data loss & degradation. • Instrument data degradation & loss • Data interruption & loss requirements are critical to Science goals & significantly drives system design (capture 99.99% of the data, 95% of the time). • Geosynchronous orbit • Selected to support continuous data downlink capability; drives mass, launch vehicle, & propulsion requirements & places SDO in high radiation environment. • Long mission life (5 year) • Drives reliability (especially of mechanisms), redundancy, & radiation requirements. • Instrument pointing & stability • Tight pointing & stabilization needed to meet instrument requirements. • Technology enhancements – 4k x 4k CCDs to meet science requirements.

  19. Programmatic Changes since SCR • ICR decision: SHARPP instrument suite (KCOR, Magritte, & SPECTRE) removed from SDO & replaced with the Atmospheric Imaging Assembly (AIA) from LMSAL. • Contract in place late Oct 2003. LMSAL team was already working on SDO’s HMI instrument, so they were familiar with Project, requirements, interfaces, & design. • From a science standpoint, AIA replaces the science provided by Magritte & SPECTRE. AIA based on successful TRACE telescope design/heritage. Coronagraph no longer part of mission. • Accommodation: S/C resources available, S/C mods minor, HMI/AIA SOCs combined, LMSAL providing GTs. • Optics Free Spectrometer (OFS) assembly removed from EVE (approved by NASA HQ SEC) due to the high development risk (identified at SCR). • EVE determined an alternate & low risk approach for performing calibration checks. Involves incorporation/use of additional calibration photo diodes to monitor short term calibration changes on-orbit & sounding rocket under flights for periodic checks of absolute calibration changes. • As part of ICR approval letter from NASA Code S, Project received direction to use 4/08 as the new launch date to meet LWS funding profile. • GSFC Instrument Managers in place for all PIs. • GSFC mgmt. assignments associated with Lunar Exploration effort resulted in Ken Schwer moving to National Polar-orbiting Operational Environmental Satellite System (NPOESS) Preparatory Project (NPP) and Liz Citrin replacing Ken as the SDO PM (post PDR transition).

  25. Telescope Assembly Guide Telescope CCD/CEB Radiators AIA – Atmospheric Imaging Assembly PI: Alan Title, LMSAL AIA Overview: AIA studies the active dynamics of the solar atmosphere in high spatial resolution and high temporal cadence in several spectral (and therefore temperature) regions including the extreme ultraviolet (EUV). AIA focuses on the evolution of the magnetic field in the Sun’s atmosphere and its interaction with embedded and surrounding plasma including the flaring and non-flaring corona. Measurement Requirements:AIA measures stabilized full-disk ~1.2 arcsec resolution images of the solar chromosphere, transition region and inner corona over a temperature range of 0.005 to 20 MK in eight spectral channels with an image cadence of 10 seconds. This will allow discovery of the causal relationship between the relatively slow magnetic field revolution and energy storage, and the rapid energy releases in flares and CME’s, which have a direct effect on earth’s environment. Project Drivers: Development of 4k x 4k CCD’s and associated readout electronics, and the schedule recovery from the late inclusion of AIA on the SDO mission. AIA Implementation: Lockheed Martin Solar Astrophysics Laboratory (LMSAL) is responsible for the AIA investigation including the development, delivery and operation of the AIA instrument and the development and conduct of the AIA science data processing. The Smithsonian Astrophysical Observatory (SAO) is a key partner (subcontractor) both scientifically and in development of major instrument subsystems. Current Status: A definitized contract was established February 12, 2004 for Phases A and B. Heritage: TRACE, SOHO/EIT Milestones: Nov ’03: Ltr. Contract; begin Phase A Mar ’04: PDR-1 Apr ’04: PDR-2 Nov ’04: CDR Feb ’07: Deliver to GSFC Apr ’08: Launch

  27. EVE - EUV Variability Experiment PI: Tom Woods, LASP/CU Instrument Overview: EVE measures the solar extreme ultraviolet (EUV) irradiance as needed for Space Weather operations and critical for LWS geospace research of the ionosphere and thermosphere. Measurement Requirements: Measure the solar EUV irradiance shortward of 105 nm, with 0.1 nm resolution longward of 10 nm, with 20-sec time cadence, and with 25% absolute accuracy over the prime 5-year mission. Project Drivers: Obtaining 1024 x 2048 CCDs from MIT on schedule, obtaining flight gratings on schedule, obtaining SDN and S/C Simulator electronics from GSFC on schedule, and new CCD radiator design (prototype radiator under test now). Current Status: In Phase B, preparing for PDR (Dec. 17/18). Also, descoped the OFS subassembly as risk mitigation for schedule. Replaced the OFS in-flight calibration capabilities by extending ESP spectral coverage, adding zeroth-order diode traps for MEGS, and requiring annual underflight rocket calibrations. Has little or no impact on science, budget, or schedule.

  43. Risk ImpactRanking Safety-related Risk: Includes the potential for personnel injury and/or damage to hardware/facilities. The SDO Risk Management process is not intended to replace the existing system safety process; safety related risks shall continue to be addressed and documented in hazard analyses. Safety related risk shall be entered into the Risk Management system only when additional resources are required (in addition to those already allocated) for hazard mitigation or when there are conflicting priorities regarding Safety, Mission Performance and/or Project Execution. Mission Performance-related Risk: Includes the potential for impact to Flight/Ground segments during operations (i.e., "end products" performing their desired functions in their operational environments). This aspect of risk addresses the potential of not meeting mission requirements, possibly resulting in degraded science or total loss of mission. Project Execution-related Risk: Includes the potential for impact to development activities or the ability to deliver the required product within the allocated budget, schedule and technical resources. This aspect of risk addresses programmatic risk related to delivering a fully functioning observatory to the launch site on time and within budget.

  44. Risk Likelihood Ranking • SDO Likelihood Ranking Has Three Scales • Safety Risks are Ranked Using the Scale Defined in NPG 8715.3 • Mission Performance Risks are Ranked Using a Logarithmic Scale • Project Execution Risks are Ranked Using a Linear Scale
