| Description | we wish to observe the atomic silicon fine structure lines of atomic silicon at 129.7 and 68.5 microns towards orion-kl. these transitions have not previously been detected in the interstellar medium and are of considerable importance for the determination of the fraction of silicon depleted into interstellar grains in molecular clouds. |

| 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. |
