The High Energy Astrophysics Science Archive Research Center (HEASARC) is the
primary archive for NASA's (and other space agencies') missions studying
electromagnetic radiation from
extremely energetic cosmic phenomena ranging from
black holes to the Big Bang. Since its
merger with the Legacy Archive for Microwave Background Data Analysis
(LAMBDA) in 2008, the HEASARC
archive contains data
obtained by high-energy astronomy missions observing in the
extreme-ultraviolet (EUV), X-ray, and gamma-ray bands, as well as data from
space missions, balloons, and ground-based facilities that have studied the
relic cosmic microwave background (CMB) radiation in the sub-mm, mm and
cm bands.
The HEASARC is a member of the NASA Astronomical
Virtual Observatories (NAVO) where we work with other NASA archives to
ensure comprehensive and consistent VO access to NASA mission datasets.
Users may now query the HEASARC's catalogs using VO-enabled services and
specialized tools. This page describes
how to get to the HEASARC VO-enabled
services and provides information on other HEASARC VO activities.

- NuSTAR Caldb Update (30 Jun 2025)
The NuSTAR FPM caldb was updated to version 20250630. This release includes a new clock correction file, v208 using a new temperature model. Please see the release notes for more details.
- IXPE DU2 Anomaly (26 Jun 2025)
IXPE's Detector Unit 2 (DU2) is operating in an anomalous but stable and functional state since 14 April 2025. The detector response has changed and the data processing is being adjusted. The spectral response has been corrected. The response for polarimetry and background filtering are being recalibrated. The data for observations after 10 May 2025 are being made available with DU2 event data removed. After the processing adjustments are completed and tested, new data sets will be released to HEASARC with DU2 included.
