The '''Nuclear Spectroscopic Telescope Array''', or '''NuSTAR''', was intended to be a space-based [[X-ray]] [[telescope]] such as [[Chandra X-ray Observatory]] and [[XMM-Newton]]. The program was cancelled in February 2006 as [[NASA]] presented its 2007 budget.  On [[September 21]], [[2007]] it was announced that the program had been restarted, with an expected launch in 2011 <ref>http://www.space.com/scienceastronomy/070921_nustar_restart.html</ref>.

'''NuSTAR''' was intended to use [[grazing incidence]] mirrors to focus high energy X-rays from [[astrophysics|astrophysical]] sources. Its primary goals were to conduct a deep survey for supermassive [[black hole]]s, study particle acceleration in [[active galaxy|active galaxies]], and measure radioactive isotopes in young [[supernova remnant]]s in our own [[Milky Way|Galaxy]]. NuSTAR was a [[NASA]] Small Explorer class mission. The Principal Investigator was Fiona Harrison, of the [[California Institute of Technology]]. Other partners included the [[Jet Propulsion Laboratory]], [[Columbia University]], the [[Stanford Linear Accelerator Center]], the [[University of California, Santa Cruz]], [[Lawrence Livermore National Laboratory]], [[Sonoma State University]], and the [[Danish Space Research Institute]]. NuSTAR's planned launch date was February 2009. It was planned to cost [[NASA]] a total of US$134,000,000.

[[Columbia University]]'s contribution centered on developing the curved glass used in the array, which was formed using specific heat cycles in specialized slumping ovens.  Most of this research took place at Columbia's [[Nevis Laboratories]] research facility in Irvington, NY.
