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 2019 (subject to further extension by the 2019 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 Users' Committee (NUC) is a group of 5-10 astrophysicists
representing a wide range of community interests who provide the NuSTAR
project with broad-based input about the needs and priorities of the NuSTAR
user community during the extended operational mission phase.
The NUC is the primary interface between the NuSTAR community and the NuSTAR
project and NASA headquarters and assists the NuSTAR Principal Investigator
and Project Scientist during NuSTAR's operational phase and in preparation
for future Senior Reviews.
- NuSTAR Cycle 5 Results (17 Jun 2019)
The list of NuSTAR targets recommended by the Cycle 5 peer
review is now available. Cycle 5 observations will start to be
routinely performed on July 1, 2019. Evaluations will be sent
to all NuSTAR Cycle 5 proposal PIs in the next few weeks.
- NuSTAR CALDB Update (15 Mar 2019)
The NuSTAR CALibration DataBase was updated on March 15, 2019 (CALDB version 20190314). This updates the NuSTAR clock correction file to version 91, valid through 2019-03-14.
- NuSTAR CALDB Update (05 Mar 2019)
The NuSTAR CALibration DataBase was updated on March 5, 2019 (CALDB version 20190228). This updates the NuSTAR clock correction file to version 90, valid through 2019-02-28.
- NuSTAR Cycle 5: Proposal Due Date March 29, 2019, Start of Observations July 1, 2019 (26 Feb 2019)
The start of Cycle 5 (11 month duration) observations has been changed from
June 1 to July 1, 2019 (no change in available total time). Cycle 5
proposers, please take this into account for visibility windows. Cycle
4 observations will extend into June. Please see the
Guide for Proposers for more details.
- NuSTAR Guest Observer (GO) Cycle 5 Deadline is now TBD (17 Jan 2019)
The due date for NuSTAR Cycle 5 proposal submission is
See the amendment recently posted at NSPIRES.
A new date will be set when the government reopens, with some additional time provided since some proposers have been unable to work. Please note that the proposal submission website (ARK/RPS) will remain open as long as possible to accept proposals.
