NASA RESTARTS TELESCOPE MISSION TO DETECT BLACK HOLES

WASHINGTON -- NASA has made a decision to restart an astronomy mission that will have greater capability than any existing instrument for detecting black holes in the local universe

The Nuclear Spectroscopic Telescope Array, or NuSTAR, will expand our understanding of the origins and destinies of stars and galaxies NASA had stopped the study effort on the NuSTAR mission in 2006 due to funding pressures within the Science Mission Directorate

"We are very excited to be able restart the NuSTAR mission, which we expect to be launched in 2011," said Alan Stern, associate administrator for the Science Mission Directorate at NASA Headquarters in Washington "NuSTAR has more than 500 times the sensitivity of previous instruments that detect black holes It's a great opportunity for us to explore an important astronomical frontier We are getting more and more from the science budget we have, and the restart of the highly-valued NuSTAR mission is an example of that "

NuSTAR will bridge a gap between the 2009 launch of the Wide-field Infrared Survey Explorer and the 2013 launch of the James Webb Space Telescope The spacecraft will map areas of the sky in the light of high-energy X-rays and complement astrophysics missions that explore the cosmos in other regions of the electromagnetic spectrum

"NuSTAR will perform deep observations in hard X-rays to detect black holes of all sizes and other exotic phenomena," said Jon Morse, director of the Astrophysics Division at NASA Headquarters "It will perform cutting-edge science using advanced technologies and help to provide a balance between small and large missions in the NASA astrophysics portfolio "

NuSTAR is a part of NASA's Explorer Program The program provides frequent, low-cost access to space for missions with small- to mid-sized spacecraft NuSTAR originally was selected from proposals submitted in response to an announcement of opportunity in 2003 Fiona Harrison of the California Institute of Technology, Pasadena, is the NuSTAR principal investigator

NASA expects to select three additional Small Explorer missions for flight in the first half of the next decade through a competitive selection within the astrophysics and heliophysics scientific communities

NASA's Jet Propulsion Laboratory, Pasadena, Calif manages the NuSTAR mission The Goddard Space Flight Center, Greenbelt, Md , manages the Explorer Program for the Science Mission Directorate Orbital Sciences Corp , Dulles, Va , is the industry partner for the mission
