Beginning early science operations a decade ago in 2011, the Atacama Large Millimeter/submillimeter Array (ALMA) will be in the midst of Cycle 8 observations during the January 2022 American Astronomical Society meeting. Over the past ten years, ALMA has provided unprecedented sensitivity, image fidelity, and resolution at  millimeter and submillimeter wavelengths, supporting the research interests of more than 8000 PIs and co-Is. From Solar System objects to the earliest galaxies, ALMA observations have produced breathtaking images and opened new discovery space. ALMA data have been published in 2400+ refereed publications. 

This Special Session will describe ALMA news, capabilities, and expectations for ALMA performance and science in the next few years and plans for its upgrade in the 2030 timeframe. In that period, ALMA will complete its frequency coverage of the millimeter window. ALMA's bandwidth will be increased to enhance simultaneous spectral range and continuum sensitivity, even as its line sensitivity is increased via receiver upgrades, an upgraded correlator, and upgrades of the systems connecting them. Higher resolution imaging is being explored, both on the exceptional site and as part of extremely long baseline imaging arrays. 

The session will feature science talks presenting a wide range of recent, exciting ALMA science results and will also highlight the support available to the community from the North American ALMA Science Center (NAASC) at the NRAO.
