And try not to leave it in that environment. Shuttles etc. are
pretty dirty environments for space astronomy.

Abstract
Part of the objective of the cooled infrared telescope on
Spacelab 2 was to determine the particle environment around the
Space Shuttle. The telescope scanned the sky in six wavelength
bands ranging from 2 to 100 microns with high time resolution.
Dust particles could be identified from their particular
signature in the data stream. Particle data from about 4 h early
in the mission were analyzed in terms of size, color temperature,
velocity, and time. The 1100 particles that were seen were slow
moving and ranged in color temperature from 190 to 350 K with a
few much hotter. The minimum detectable diameter is between 5 and
13 microns, depending on temperature. The size distribution
resembles sample distributions collected at a Shuttle preparation
facility. Although particle detection rates varied widely with
time, no specific events were identified to be associated with
particle production. It was not possible to determine the
particle composition, although it was probably not ice.

Abstract
A small helium cooled IR telescope flown on Spacelab-2 in
July/August 1985 was used to make infrared measurements between 
2 microns and 120 microns. New data were obtained on the structure
of the Galaxy at 2 microns and 7 microns showing it to be much
broader at these wavelengths than at longer wavelengths. The IR
emission due to contamination from the Shuttle was found to be
greater than anticipated, indicating the induced environment to
be much higher than the planned limits. Aspects of superfluid
helium management in zero-G and of a cryogenically cooled
telescope design were also tested.
