Relevance to NASA's Strategic Plan
A Brief History of the High Energy Astrophysics Science Archive Research CenterThe HEASARC was established in November 1990 by NASA at its Goddard Space Flight Center as the designated archive for high-energy astrophysics (HEA) datasets from space-based observatories, and Dr. Nicholas White was appointed its director. It was the first of several wavelength-specific NASA science archive research centers. The motivation for these centers was to create an environment that could sustain archival data in usable form, after the mission that obtained these data ended. A crucial part of this new approach was to co-locate the archive with scientists actively undertaking research, connecting the data holdings with the necessary science expertise. It was also anticipated that a multi-mission approach to the archive would lead to cost savings for future missions by reusing software and archive resources.
The HEASARC was selected as the first wavelength specific archive center because of the then imminent (as of 1990) ROSAT, CGRO, ASCA, and RXTE missions. These missions each had a unique and complementary capability that could only have been fully exploited if the data were stored within a single archive. Another concern at that time was that the data from several high energy astrophysics missions from the 1980s and 1970s were on the verge of being lost. The HEASARC therefore devoted resources to retrieving data from a number of these early missions (and, where necessary, converting them to modern formats), including OSO-8, HEAO-1, Einstein, and EXOSAT.
In the summer of 1999, with NASA HQ concurrence, the Harvard-Smithsonian Center for Astrophysics became a partner in the HEASARC organization. The primary objective of this partnering is to bring together the strengths and experience of both organizations to provide the best possible HEASARC service.
Since then, the HEASARC has provided access to data from a number of operational missions, including the BeppoSAX, Chandra, XMM-Newton, INTEGRAL, Swift Gamma-Ray Burst Explorer, Suzaku, Fermi and NuSTAR missions.
In the summer of 2008, the HEASARC merged with NASA's cosmic microwave background (CMB) archive LAMBDA (Legacy Archive for Microwave Background Data Analysis). The expanded HEASARC's data holdings thus now include data from the NASA CMB missions WMAP, COBE, and SWAS, as well as from ground-based and/or balloon-based experiments such as ACT and SPT.
In August 2008, Dr. Alan Smale succeeded Dr. Nicholas White as the Director of the HEASARC.
As of the time of writing (March 2016), the HEASARC's archive contains data from 32 HEA missions and 25 CMB experiments and/or missions. The HEASARC will continue to archive data from new and upcoming HEA missions, including Hitomi (formerly Astro-H) (launched in February 2016) and NICER (to be launched in early 2017) missions, and from additional CMB experiments, including BICEP/Keck, ACTpol and SPTpol.

The HEASARC welcomes your participation in a brief survey to capture how users access and utilize HEASARC data, software, and services. The outcome(s) of this survey will be used to guide, prioritize, and plan our activities and development in the coming years. It contains 18 questions, generally takes just a few minutes to complete, and your answers will remain totally anonymous. We thank you in advance for your valuable feedback.
