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 (14 Jun 2017)
The NuSTAR CALibration DataBase was updated on June 14, 2017 (CALDB version 20170614) This updates the NuSTAR clock correction file to version 72, valid through 2017-06-14.
- Happy 5th Birthday to NuSTAR! (13 Jun 2017)
The Nuclear Spectroscopic Telescope Array (NuSTAR) spacecraft
was launched on a Pegasus XL rocket dropped from a Lockheed L-1011 "TriStar"
aircraft flying over the Pacific Ocean near the Kwajalein Atoll on June 13,
2012. Since then it has made over 2100 hard X-ray observations in science mode
which have yielded (to date) hundreds
of refereed and other publications.
- NuSTAR Cycle 3 Results (10 May 2017)
The list of NuSTAR targets accepted by the Cycle 3 peer review is
now available. Cycle 3 observations will start to be routinely performed on
June 1, 2017. Written evaluations will be sent to all NuSTAR Cycle 3 PIs in
the next few weeks.
- NuSTAR CALDB Update (05 May 2017)
The NuSTAR CALibration DataBase was updated on May 5, 2017 (CALDB version 20170503). This updates the NuSTAR clock correction file to version 71, valid through 2017-05-03.
- NuSTAR CALDB Update (24 Apr 2017)
The NuSTAR CALibration DataBase was updated on April 24, 2017 (CALDB version 20170419). This updates the NuSTAR clock correction file to version 70, valid through 2017-04-19.
