A liquid helium cooled infrared telescope (IRT) was to be |
|
flown in July 1985 on Spacelab 2. The instrument is |
|
designed to measure both diffuse and discrete infrared |
|
astronomical sources, including the zodiacal light, |
|
galactic, and extragalactic components, as well as to |
|
evaluate the induced Orbiter environment. The focal plane |
|
contains ten photoconductive detectors covering six broad |
|
bands from 2 to 120 microns. Each detector has a 0.5 by |
|
1.0 deg field of view optimized for detection of extended |
|
sources of IR radiation. Except for the 2 micron |
|
detector, the system noise is limited by the sky |
|
background noise. The measurements planned for the IRT |
|
use the 1 meter base of the Plasma Diagnostic Package |
|
(PDP), an already existing SL 2 experiment, as the glow |
|
generating surface. The measurements are repeated |
|
changing the position of the PDP, the attitude of the |
|
Orbiter, and the ram direction in an effort to remove |
|
both the thermal component of the PDP emission and the |
|
cosmic background radiation. |
