we propose to map the orion a molecular cloud complex, including omc-1, omc-2, and omc-3, using the isophot c200 camera and the 200 um filter. our iso 200/100um mapping program of molecular clouds in the dlemke.isdust gt program has been very succesful and has shown that the isophot 200 um capability enables us to detect the very cold dust condensations in dense molecular cloud targets which are probably the earliest pre-protostellar stages, most of them not detected by iras at 100 um. because of the visibility constraints the orion molecular cloud a was not included in our original autumn launch target list. neither is it being mapped at 200 um by any other iso observer(s). the orion a molecular cloud is, however, the best-studied star formation region in our neighbourhood. the isophot 200 um mapping would provide a new and unparalleled data set for orion mc. being the nearest high-mass star formation region the orion mc can also serve as a template object for other, more distant star formation regions. ==================================================================== ==> ====================================================================

Mission Description
The Infrared Space Observatory (ISO) was the worlds first true orbiting infrared observatory. Equipped with four highly-sophisticated and versatile scientific instruments, it was launched by Ariane in November 1995 and provided astronomers world-wide with a facility of unprecedented sensitivity and capabilities for a detailed exploration of the Universe at infrared wavelengths.
