NASA has selected a team led by the University of Arizona, Tucson, to provide
the primary near-infrared science camera for the Next Generation Space Telescope
(NGST), NASA’s successor to the Hubble Space Telescope.

Scheduled for launch in 2010, the new telescope’s primary science objective will
be to look back to an extremely important period in the early history of the
Universe when the first stars and galaxies began to form shortly after the big
bang.

To achieve this goal, the NGST will require much more light-gathering capability
than Hubble, meaning it will need a much larger primary mirror. At approximately
6 meters (20 feet) in diameter, NGST’s primary mirror will be more than two-and-
a-half times as large as the Hubble telescope, which is scheduled for
“retirement” in 2010 after a 20-year mission in space.

In addition to a large light-gathering mirror, NGST will need to operate at near-
and mid-infrared wavelengths to better detect the light from extremely distant
and faint objects. NGST will study infrared (heat) emissions from objects that
formed when the Universe was between one million and a few billion years old. It
will be capable of seeing objects 400 times fainter than those currently studied
with large ground-based telescopes or the current generation of space-based
infrared telescopes. Its tennis-court-size sunshade will help eliminate heat from
the sun, which is necessary for reducing heat “pollution” from the surrounding
environment.

The telescope will be built by an industry team that NASA will select later this
summer.

The winning primary camera team includes members from the University of Arizona;
Lockheed-Martin Advanced Technology Center, Palo Alto, Calif.; EMS Technologies,
Ottawa, Canada; and COMDEV, Ltd., Cambridge, Canada, and will be led by Dr.
Marcia Rieke of the University of Arizona. In addition to selecting the main
imaging camera, NASA has chosen the U.S. portion of an international team that
will construct a mid-infrared instrument. The members of this team are Dr. Thomas
Greene, NASA’s Ames Research Center, Moffett Field, Calif.; Dr. Margaret Meixner,
University of Illinois, Urbana-Champaign; and Dr. George Rieke, University of
Arizona.

These scientists, lead by Dr. George Rieke, will work in collaboration with
scientists and engineers led by Dr. Gene Serabyn from NASA’s Jet Propulsion
Laboratory, Pasadena, Calif., and the European Space Agency to enable NGST to see
farther into the infrared portion of the spectrum. This capability will permit
NGST to study stars forming inside dense clouds of interstellar dust that block
Hubble’s vision.

NASA has also selected several scientists to serve, with the principal instrument
scientists, on the NGST science working group. This group will provide scientific
guidance during the development of the telescope. The selected scientists are Dr.
Heidi Hammel, Space Science Institute, Ridgefield, Conn.; Dr. Simon Lilly, ETH-
Hoenggerberg, Zurich, Switzerland; Dr. Jonathan Lunine, Lunar and Planetary
Laboratory, Tucson, Ariz.; Dr. Mark McCaughrean, Potsdam, Germany; Dr. Massimo
Stiavelli, Space Telescope Science Institute, Baltimore; and Dr. Rogier
Windhorst, Arizona State University, Tempe.

NGST is managed for NASA by the Goddard Space Flight Center, Greenbelt, Md.
Contributions come from a number of industry, academic and government partners.
