Tomography of the intergalactic medium over a range of redshifts, backward through the Epoch of Reionization and into the Dark Age requires new generations of radio instruments, ones capable of detecting faint signatures of the
redshifted 21 cm Hydrogen line. I will discuss the Hydrogen Epoch of Reionization Array concept (HERA), which was proposed in the Astro2010 process. A progression of larger and more scientifically capable arrays will target detection and characterization of multidimensional power spectra, and ultimately, direct imaging of discrete structures at higher and higher redshift. With the final stage corresponding to about a square kilometer of collecting area and a few kilometer geographic extent, the end-stage technical challenges will be substantial, in particular with regard to signal processing and calibration. Each step up in array size, will enable incremental deployment and demonstration of new technologies and techniques to achieve new science, starting with present-day pathfinders. At about an order magnitude larger scale, the next generation array is anticipated to be practical to build and operate at about the middle of the decade.
