  • The Community Missions Office is the focal point for bringing the cumulative expertise and experience of STScI personnel to tune relevant support for mission science operations, data archiving, proposal peer review, and education/outreach. Our philosophy is to integrate the scientific perspective into all aspects of missions to maximize the scientific return through cost effective application of our products, services, and operations abilities. Our motivation is to reduce operations costs for community-led missions by leveraging the science operations systems we already have in-place here at STScI. Experiences on several of our projects suggests that we are being successful in this regard.
  • Here are the 3 primary goals the institute’s CMO strives to achieve.
  • You clearly know the landscape of astronomy missions and facilities on the ground and in space is quite diverse and holds promise for many exciting discoveries. Our aim is to offer to the community the use our scientific and technical experiences to help minimiize duplication of effort, help avoid known operational pitfalls. But we, as members of this same community, are also keenly interested in identifying and collaborating in future missions that will carry astrophysics forward in a number of areas.
  • These are the subset of those missions that we are or will be playing a role in. Obviously some, like HST and JWST, we play a key role. Others we play an important supporting role by carrying out a specific operations task that is integrated with an external science operations center or team.
