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 (04 Dec 2017)
The NuSTAR CALibration DataBase was updated on December 4, 2017 (CALDB version 20171204). This updates the NuSTAR clock correction file to version 76, valid through 2017-12-04.
- NuSTAR Guest Observer (GO) Cycle 4 Solicitation (20 Nov 2017)
Research Opportunities in Space and Earth Science for
2017 (ROSES-17) Amendment 38 (released on Oct 6, 2017) contains the
revised text for Appendix D.10 soliciting proposals to the NuSTAR GO
Cycle 4 opportunity. The due date for proposal submission is Jan 19,
2018. Proposals should be submitted via the HEASARC's ARK Remote
Proposal System (RPS). For more information about
this AO, please visit the NuSTAR Proposal
- NuSTAR Probes Black Hole Jet Mystery (31 Oct 2017)
Using NASA's NuSTAR space telescope and a fast camera called
ULTRACAM on the William Herschel Observatory in La Palma, Spain, Gandhi et al.
have been able to measure the distance that particles in the jets from the
black hole binaries V404 Cyg and GX 339-4 travel before they "turn on" and
become bright in visible light. This distance called the "acceleration zone"
is determined to be 0.1 light seconds (30,000 km) in these systems. See the
study in Nature Astronomy.
- NuSTAR Users Commitee: Call for Self Nominations (18 Oct 2017)
NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) high-energy
mission announces the creation of the NuSTAR Users Committee (NUC).
The NUC will provide community advice and feedback to the project, to
ensure that the interests of the guest investigator community are
well-served by the project. Membership on this committee is open to the world,
and we intend a committee that is diverse in terms of career stage, gender, and
scientific focus. Letters of self-nomination to
serve on this committee are due by November 3rd, 2017.
- NuSTAR CALDB Update (03 Oct 2017)
The NuSTAR CALibration DataBase was updated on October 3, 2017 (CALDB version 20171002). This updates the NuSTAR clock correction file to version 75, valid through 2017-10-02.
