Scientific paper
Six instruments for Space Sciences are presented as potential external payloads, which need accommodation on the SSF truss or on the Columbus Attached Laboratory (CAL) by means of a terrace or balcony. Three of them (ORFEUS, SUN, UTEF) require pointing platforms with 20-arcsec stability and capability of rotation around the line of sight. Two (GAUSS, LOBSTER) are satisfied with a pointing stability of 1 arcmin. For DUSTWATCH, SSF may be an acceptable platform. Two contamination aspects are of concern: degradation of UV coatings due to molecular deposition and increased background radiation due to local molecular and particulate scattering and emission. The scientific objectives address forefront problems in a wide energy range, from gamma-rays, through X-rays and the extreme UV, down to the far-UV and the UV. One instrument (SUN) is the European forerunner for UV imaging interferometry from Space.
