Implementing “Portals to the Universe”, April 2012 Herschel/NHSC 2
Three instruments: imaging at {70, 100, 160}, {250, 350 and 500} µm; spectroscopy: grating [55-210]µm, FTS [194-672]µm, Heterodyne [157-625]µm; bolometers, Ge photoconductors, SIS mixers; 3.5m primary at ambient T
ESA mission with significant NASA contributions, May 2009 – February 2013 [+/-months] cold
[OIII] 88 mmz = 3.04
Herschel: Cornerstone FIR/Submm Observatory

Herschel Mission Parameters Userbase
International; most investigator teams are international Program Model
Observatory with Guaranteed Time and competed Open Time ESA “Corner Stone Mission” (>$1B) with significant NASA
contributions NASA Herschel Science Center (NHSC) supports US community
Proposals/cycle (2 Regular Open Time cycles) Submissions run 500 to 600 total, with >200 with US-based PI (~x3.5)
Users/cycle US-based co-Investigators >500/cycle on >100 proposals
Funding Model NASA funds US data analysis based on ESA time allocation
Default Proprietary Data Period 6 months now, 1 year at start of mission

Best Practices: International Collaboration Approach to projects led elsewhere needs to be designed
carefully NHSC Charter remains firstly to support US community But ultimately success of THE mission helps everyone Need to express “dual allegiance” well and early to lead/other centers
NHSC became integral part of the larger team, worked for Herschel success, though focused on US community participation Working closely with US community reveals needs and gaps for all
users Anything developed by NHSC is available to all users of Herschel Trust follows from good teaming: E.g. NHSC scientists contributed half
the technical reviews of proposals
Mantra of “learn by helping” was seen by all as win-win NHSC helps with tasks that generate insight into instruments,
software, workings of system That insight proved essential to effective user support

Best Practices: User Support Targeting User Support has different emphases at different mission phases
Need to target messages, medium, mode of support to each phase Start early to make sure potential users understand how to use it Provide same tools for the whole spectrum of users, GTO - GO –
Archival Talk to non-GTO early: they will have different takes and needs Aim support at non-specialists: the whole community is potentially
interested, if properly engaged, and will enrich the science
Herschel payoff was high access for US community (48.5% of time) NHSC User Support model was ahead of EU effort, especially pre-
Launch NHSC worked with HSC to deploy model in EU, e.g. Data Analysis
Workshops
User surveys using mail-in questionnaires, informal data gathering

Best Practices: User Support Evolution Example #1: As US-based Herschel users grew in number, the
model of hosting teams to support their data analysis became unworkable Success rate of US PI and co-I teams 2-3x anticipated rates for “Key
Projects,” OT1, OT2 NHSC response:
Organize hands-on data reduction workshops, 20-40 participants each Take those sessions onto the web with webinar technology Schedule remote help sessions, and provide self-paced web-tutorials
Example #2: Hardware requirements for reducing large data sets exceeded by far anticipated sizing, to well beyond what most investigator teams could afford to buy
NHSC Response: Set up dedicated well-sized hardware to be reserved & used remotely A “virtual machine” (private, secure environment) is deployed for
each team for days to weeks, then destroyed

Best Practices: Build on Other Missions From Spitzer:
Observation Planning Tool Spot became H-Spot (now also SOFIA-Spot) Team structure within NHSC: Combined scientists + engineers User interactions: Start Panel early, diversify it, listen hard in other
forums! Data Analysis Funding scheme and policies: RSA, formulas, priority
levels for uncertain cryo-mission duration
ISO Collaboration model: “learn by helping” Resident US Astronomer at Herschel Science Center Background estimator, other tools adapted for Spitzer, then for
Herschel
IPAC environment, team member progression to new projects help New missions still need to work hard at not re-inventing the wheel
From Portals to the Universe: The NASA Astronomy Science Centers (NRC Report, 2007)
“Successful research using archival data sets
is dependent on the resident expertise and
corporate memory that resides at the science
centers.”

IPAC: The Infrared Processing and Analysis Center
IPAC started out as the NASA center of science, operations and data expertise for IR-submm astrophysics, then Exoplanet Science was added: Carries out challenging data processing tasks essential to the science
return from large astronomy projects All-sky surveys, Great Observatories
Supports NASA Astrophysics missions as a Science Center Interfaces between project and astronomical community Manages science programs on behalf of NASA Conducts efficient, science-centered operations
Develops, maintains science data archives, access and analysis tools Integrates literature and survey data into thematic knowledge bases
Conducts education and outreach efforts aimed at the general public
IPAC addresses the Astro2010 and NASA Astrophysics Themes NEW WORLDS (Exoplanet Exploration) COSMIC DAWN (Cosmic Origins) PHYSICS OF THE UNIVERSE (Physics of the Cosmos)
