"HETDEX Status"

There has been considerable progress on HETDEX since our previous update. We will bring you up to date on the overall project, including the timeline, planning, budget, observing, data access, and use for the general community. We will discuss the on-going and planned dark energy experiments. The strength of HETDEX remains in measuring the evolution of dark energy, given our focus higher redshift. We will highlight the multiple science cases that HETDEX and VIRUS will address, including parallel observations.
