The High Energy Astrophysics Archival Research Center (HEASARC) was founded at GSFC in November 1990 as the NASA astrophysics discipline node to support multi-mission X-ray and gamma-ray astronomy research by providing a unified archive and software structure aimed both at 'legacy' missions such as Einstein, EXOSAT and Ginga, and upcoming missions. Contemporaneously with its inception, occurred the launch of the first of a new generation of high-energy astronomy observatories, ROSAT and CGRO (with ASCA to follow 2 years later). In the two decades since then, the HEASARC's high-energy astronomy archive has grown so that it presently contains 35 TB of data from 28 orbital missions, 8 of which (RXTE, Chandra, XMM-Newton, INTEGRAL, Swift, Suzaku, AGILE and Fermi) are currently operational. The HEASARC is now the designated archive which supports NASA's Physics of the Cosmos theme and, as such, the Legacy Archive for Microwave Background Data Analysis archive at GSFC, with its data and expertise from CMB missions such as COBE and WMAP was merged into the HEASARC a couple of years ago.
We present some of the main highlights and challenges during the history of the HEASARC, and discuss some of its the upcoming new initiatives and developments, including the arrival of data from more high-energy (e.g., MAXI, NuSTAR, Astro-H and GEMS) and CMB (e.g., SPT and ACT) facilities, the unveiling of Xamin, a next-generation archive interface, and the role of the HEASARC in the Virtual Astronomical Observatory.
