ASTRONOMY:
Test Flight Added for Future Space Telescope
Robert Irion
ROCHESTER, NEW YORK--It appears that researchers will have to wait nearly a decade for the Hubble Space Telescope's successor to take wing. NASA officials have decided to test the Next Generation Space Telescope's demanding technology in a small-scale version, described here last week at a meeting of the American Astronomical Society, before forging ahead with the real thing. The technological delays that led to the shakedown mission will push the launch of the full telescope back another year to 2009 at the earliest.
