1. LSST SLAC Office of Communications August 8, 2016 Communications Roadmap

2. 2 LSST Communications Proposal Objectives Increase visibility of LSST camera project and coordinate with project leads to promote LSST as top priority; system will produce deepest, widest, fastest views of the universe; camera will be largest ever built for ground-based optical astronomy Highlight milestones of camera construction at SLAC Explain camera technology Highlight other aspects of LSST with SLAC involvement Explain LSST science to media and general public Develop evergreen products to release at key moments Create written and multimedia resources that SLAC/LSST and media outlets can use for stories

3. 3 Topics: LSST Technology Camera DOE-funded, assembly at SLAC Big Data Database built at SLAC (NSF funding) Other Mirrors, lenses, telescope site, etc. No SLAC involvement, but provides complete picture

4. 4 Topics: LSST Science Dark Energy Science Collaboration (hosted by SLAC) Dark Energy Dark Matter Cosmology Milky Way Transient Events Near-Earth Objects
