The Nuclear Spectroscopic Telescope Array Mission - NuSTAR
NASA's latest high-energy astrophysics observatory, NuSTAR, is the first
focusing high-energy X-ray mission, opening the hard X-ray sky above 10 keV
for sensitive study for the first time. During its mission, NuSTAR will
search for black holes, map supernova explosions, and study the most extreme
NuSTAR is a Small Explorer mission led by Caltech and managed by JPL for
NASA's Science Mission Directorate. The NuSTAR Mission web site can be found
here. NuSTAR data are
being archived at the HEASARC.

Introduction to NuSTAR
NuSTAR was launched at 9 am PDT, June 13, 2012 on a Pegasus XL rocket
which was dropped
from a Lockheed L-1011 "TriStar" aircraft flying over the Pacific Ocean near
the Kwajalein Atoll.
NuSTAR is the first mission to use focusing telescopes
to image the sky in the high-energy X-ray (3 - 79 keV) region of the
spectrum. Our view of the universe in this spectral window has been limited
because previous orbiting telescopes have not employed true focusing optics,
but rather have used coded apertures that have intrinsically high backgrounds
and limited sensitivity.
During its two-year primary mission phase, NuSTAR has been observing
selected regions of the sky in order to:
NuSTAR has been approved to continue operations through 2018
by the 2016 NASA Astrophysics Senior Review of Operating Missions and to
have a Guest Observer (GO)
Program. Further information about GO proposals is available on the NuSTAR Proposals page.
- Probe obscured active galactic nucleus (AGN) activity out to the peak
epoch of galaxy assembly in the universe (at z <~ 2) by surveying selected
regions of the sky;
- Study the population of hard X-ray-emitting compact objects in the Galaxy
by mapping the central regions of the Milky Way;
- Study the non-thermal radiation in young supernova remnants (SNR), both
the hard X-ray continuum and the emission from the radioactive element
- Observe blazars contemporaneously with ground-based radio, optical, and
TeV telescopes, as well as with Fermi and Swift, so as to constrain the
structure of AGN jets; and
- Observe line and continuum emission from core-collapse supernovae in the
Local Group, and from nearby Type Ia events, to constrain explosion models.
- NuSTAR CALDB Update (03 Oct 2017)

- NuSTAR Data Analysis Guide Updated (03 Oct 2017)
The NuSTAR Data Analysis Guide was updated to version 1.9.3
- NuSTAR CALDB Update (30 Aug 2017)
The NuSTAR CALibration DataBase was updated on August 30, 2017 (CALDB version 20170817). This updates the NuSTAR clock correction file to version 74, valid through 2017-08-17.
- News Story: NuSTAR Observed This Week's Solar Eclipse (24 Aug 2017)
On August 21, for about two minutes across a swath of North
America, Earth's moon passed in front of and completely blocked out the sun,
causing a total solar eclipse. Countless people witnessed this rare phenomenon,
the first total solar eclipse in North America in 38 years. Just last week,
scientists at Caltech and JPL decided that NuSTAR, the Nuclear Spectroscopic
Telescope Array, would watch with them.
- NuSTAR CALDB Update (21 Aug 2017)
The NuSTAR FPM CALDB at the HEASARC was updated to CALDB version 20170727. This CALDB patch is a required update for using saamode=3 now available with NuSTARDAS v1.8.0., released in HEASoft 6.22
