The Event Horizon Telescope project links mm and submm wavelength facilities around the globe into a VLBI array capable of spatially resolving the nearest supermassive black holes. Towards SgrA*, the 4 million solar mass black hole at the Galactic Center, and the ~6 billion solar mass black hole in Virgo A, EHT observations at 1.3mm can resolve the ‘silhouette’ of the event horizon. First EHT observations in April 2017 achieved have been correlated and are now being processed and analyzed, with VLBI detections to all sites. This talk will provide an update on progress and describe new directions for this ultra-high angular resolution work over the coming years, including exploration of space-VLBI opportunities, new sites, and extension to shorter wavelengths.
