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.
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)
Further information about GO proposals is available on the NuSTAR proposal page.

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:
- 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 (24 Feb 2017)
The NuSTAR CALibration DataBase was updated on February 24, 2017 (CALDB version 20170222). This updates the NuSTAR clock correction file to version 69, valid through 2017-02-22.
- NuSTAR, Swift and XMM-Newton Help Solve the "Rapid Burster" Mystery (02 Feb 2017)
Simultaneous Swift, NuSTAR and XMM-Newton observations of MXB
1730-335, a curious neutron star in a binary system known as the 'Rapid
Burster', may have solved a 40-year-old mystery surrounding its puzzling X-ray
bursts, according to van den Eijnden
et al.(2016, MNRAS, 466, L98)). The neutron star magnetic
field creates a gap in the accretion disk around the star,
largely preventing it from feeding on matter from its companion. Gas builds up
there until, under certain conditions, it hits the neutron star all at once,
producing intense flashes of X-rays.
- NuSTAR Guest Observer Cycle 3 Deadline Is Near (05 Jan 2017)
The deadline for Phase-1 scientific/technical proposals for
the NuSTAR Cycle 3 GO Program is imminent: proposals are due no later than
4:30 pm EST on Friday, January 27th, 2017.
- NuSTAR CALDB Update (08 Dec 2016)
The NuSTAR CALibration DataBase was updated on December 8, 2016 (CALDB version 20161207). This updates the NuSTAR clock correction file to version 66, valid through 2016-12-07. This version is the long-awaited "corrected" clock correction file that tracks clock drift by fitting to screened clock data.
- NuSTAR CALDB Update (25 Oct 2016)
The NuSTAR CALibration DataBase was updated on October 25, 2016 (CALDB version 20161021). This updates the NuSTAR clock correction file to version 63, valid through 2016-10-21.
