GEO-CAPE Mission Status Jay Al-Saadi GEO-CAPE Program Scientist GEO-CAPE Team Meeting &International Geostationary Ocean Color and Air Quality Coordination Meeting NASA Ames Research Center, May 21-23, 2013
Structure of this workshop • Update each other about our activities • The GEO-CAPE science and mission working group studies • International mission activities* • TEMPO and its relation to GEO-CAPE • DISCOVER-AQ and companion field activities • Hosted payload activity in the US, including field trip • Ongoing ESTO Instrument Incubator activities • Allow plenty of time for working/planning in breakout groups • Science feasibility studies to inform mission requirements • International collaboration • Algorithm development • Cal/Val activities • Increasing engagement and preparation of end users • Hosted payload activities • Etc etc... *Though the international mission plenary talks are on Thursday morning because of initial scheduling considerations, the entire 3-day meeting is a joint meeting.
Taking stock • We’ve come a long way • We’ve moved past many of the tensions between communities (science/applications, ocean/atmosphere) by focusing on what we have in common • We were the first DS study team to accept that cost would be a primary factor, and agreed as a community to do something constructive about it by embracing the potential of hosted payloads • We’re going in the right direction • Global scale time-resolved Earth science from space is the next frontier. The first 2 Earth Venture orbital selections proposed novel ways to get it. • The international constellation partnerships are essential for accomplishing globally relevant science/applications using geostationary vantage point • It takes a village • All of this progress is a result of your many years of sustained work • Proposing to all 3 threads of EV and winning in 2 (DISCOVER-AQ, TEMPO) • Sustained proposing and winning of R&A, Applied Science, and ESTO awards • Collectively, we are advancing the science, applications, engineering, and NASA programmatics – all of which are critical to our success
GEO-CAPE Evolution Since Decadal Survey • GEO-CAPE mission concept as described in the Decadal Survey was studied in 2010 using a planning payload representative of the instrumentation needed for GEO-CAPE measurements • Implemented as a “dedicated” NASA geostationary mission • All instrumentation would fly on the same spacecraft • Ocean color measurements need companion atmospheric composition measurements (O3, NO2) for atmospheric correction • Estimated life-cycle cost ~$1.5B => not affordable this decade • GEO-CAPE stakeholders have developed an alternative implementation concept (Fishman et al., BAMS, 2012) • Implement mission as secondary payloads hosted on commercial satellites • GEO-CAPE ocean color measurements can be independent of GEO-CAPE atmosphere measurements: instruments can fly separately • Significantly reduce risk and cost compared to a single dedicated mission • Phased implementation flexibility is responsive to budget uncertainties • Life-cycle cost target ~$600-700M tbc (~ same as DS cost estimate with inflation) • GEO-CAPE will be a Western Hemisphere contribution to integrated global observing systems for air quality and ocean biogeochemistry Affordable, scalable mission that minimizes risk and optimizes scientific value
What does TEMPO mean for GEO-CAPE? • TEMPO will provide part of the urgently-needed GEO-CAPE atmospheric measurement capability as soon as possible: launch ~2019 • Now determining which GEO-CAPE requirements will be met by TEMPO • All TEMPO measurements are part of the recommended GEO-CAPE suite, but GEO-CAPE also requires concurrent measurements of additional species including the critical tracer CO, short-lived climate forcer CH4, and aerosol precursor NH3 • TEMPO selection does not imply acceleration of full GEO-CAPE mission • Depending on future budgets and priorities, TEMPO could be a precursor or initial component of GEO-CAPE …. It’s too soon to tell • EV-I TEMPO planning 20 month operation (extension may be possible) • TEMPO is a pathfinder. It will demonstrate the use of commercially-hosted payloads to accomplish NASA Earth Science, potentially enabling affordable earlier implementation of full GEO-CAPE mission. • Coastal ocean ecosystem science mission • Full suite of simultaneous atmospheric measurements
Charge to workshop participants • Develop prioritized recommendations for FY14 and FY15 activities • Mission science, applications, and implementation studies • Continue to take advantage of leveraging opportunities • Identify collaboration with other programs (such as TEMPO) and with national and international partners, whenever it makes sense to do so • Continue to hone the definition of GEO-CAPE for HQ • Why? It has been powerful to be able to express unified community positions, such as the endorsement of a phased mission strategy • Atmosphere SWG: review, improve, and move toward endorsement of the TEMPO-GCIRI analysis of alternatives • Ocean SWG: Are there acceptable options to obtain some/all required capability in EV-sized pieces within the next decade? • Everyone: assess the “Value” frameworks for quantifying alternatives • Begin considering community inputs for the next DS
