GEO-CAPE Mission Status

1. 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

2. 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.

3. 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

4. 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

7. 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

8. 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
