The Nuclear Spectroscopic Telescope Array Mission (NuSTAR)
NuSTAR -launched June 13, 2012- is a Small Explorer mission led by the California Institute of
Technology (Caltech) and managed by NASA's Jet Propulsion Laboratory in Pasadena. The observatory is
the first focusing high-energy X-ray mission (3-80 keV) in orbit, opening the hard X-ray sky for
sensitive study for the first time.
The primary science objectives are the study of the evolution of massive black holes, of compact
objects, of the nature of the massive black hole in the center of the Milky Way, of the explosion
dynamics and nucleosynthesis in supernovae and of the nature of particle acceleration in
relativistic jets in Active Galactic Nuclei.
The Italian contribution includes the provision of the Italian Space Agency (ASI) ground station in
Malindi (Kenya) and the ASI Science Data Center (ASDC). Moreover, Italy participates to the project
with a team of scientists of the National Institute for Astrophysics (INAF) which collaborates on
the primary scientific mission goals.
The primary reference for NuSTAR is Harrison et al. 2013.

The ASDC has developed, in collaboration with the NuSTAR Team in Caltech, the NuSTAR Data Analysis Software (NuSTARDAS), the scientific data reduction software for NuSTAR. The NuSTARDAS package processes the NuSTAR FITS formatted telemetry (Level 1) data and generates calibrated Level 2 and Level 3 scientific products (event files, energy spectra, light-curves, sky images, exposure maps, ARFs, RMFs).
The NuSTARDAS package is the official software for the NuSTAR data reduction and it is used to generate the NuSTAR Science archive. The package is distributed to the users by the HEASARC as part of the HEASoft software. The NuSTAR data products are compatible with widely used high-energy astronomy data analysis packages (e.g. XSELECT, XSPEC, XIMAGE, XRONOS).
The ASDC hosts an official mirror of the NuSTAR scientific public archive.
The current release of NuSTAR public data (Data Release 7) includes over 1700 data sets. Regular updates of the archive are planned during 2015.
The NuSTAR archive is integrated in the ASDC Multi-Mission Interactive Archive (MMIA).
