The Thirty Meter Telescope: Science, observing capabilities and status // The majority of TMT construction activities are moving forward. I’ll give an update on the technical development of the observatory and describe the instruments. I’ll describe the planned first light observing capabilities and the process being followed to identify future instruments for development. The talk will be framed within the context of science, i.e. how the whole observatory is being developed to support science and what some of the guiding science programs are. Lastly I’ll mention the many ways that astronomers can provide input to guide the scientific direction of the observatory.
