3D-HST is a near-infrared spectroscopic survey with the Hubble Space Telescope designed to study the physical processes that shape galaxies in the distant Universe. This Treasury program has been allocated 248 orbits of HST time during Cycles 18 and 19.   3D-HST is surveying ~600 square arcminutes of well-studied extragalactic survey fields (AEGIS, COSMOS, GOODS-S, UKIDSS-UDS) with two orbits of primary WFC3/G141 grism coverage and two to four orbits with ACS/G800L coverage. The short acquisition images,  taken in the WFC3/F140W and ACS/F814W filters used for wavelength reference for the spectra, are also deeper than most ground-based observations. When completed, 3D-HST would provide the critical third dimension - redshift - for some ~10,000 galaxies at z>1.

3D-HST is supported by grant HST-GO-12177 awarded by the Space Telescope Science Institute.
