AbstractThe Infrared Space Observatory (ISO), a fully approved and funded project of the European Space Agency (ESA), is an astronomical satellite, which will operate at wavelengths from 3–200 μm. ISO will provide astronomers with a unique facility of unprecedented sensitivity for a detailed exploration of the universe ranging from objects in the solar system right out to distant extragalactic sources. The satellite essentially consists of a large cryostat containing at launch about 2300 litres of superfluid helium to maintain the Ritchey-Chrétien telescope, the scientific instruments and the optical baffles at temperatures between 2K and 8K. The telescope has a 60-cm diameter primary mirror and is diffraction-limited at a wavelength of 5μm. A pointing accuracy of a few arc seconds is provided by a three-axis-stabilisation system consisting of reaction wheels, gyros and optical sensors. ISO’s instrument complement consists of four instruments, namely: a photo-polarimeter (3–200μm), a camera (3–17μm), a short wavelength spectrometer (3–45μm) and a long wavelength spectrometer (45–180μm). These instruments are being built by international consortia of scientific institutes and will be delivered to ESA for in-orbit operations. ISO will be launched in 1993 by an Ariane 4 into an elliptical orbit (apogee 70000km and perigee 1000km) and will be operational for at least 18 months. In keeping with ISO’s role as an observatory, two-thirds of its observing time will be made available to the european and american astronomical community.

We present results obtained on well-known AGB and post-AGB sources with the Long Wavelength Spectrometer (LWS) and ISOCAM on board the Infrared Space Observatory (ISO). The main findings of these studies are briefly summarized.

The first detection of thermal H2O emission from an Herbig-Haro flow was made with the LWS (Long Wavelength Spectrometer) aboard ISO (Infrared Space Observatory). In addition to H2O, rotational lines of CO and OH as well as lines from [O I] and [C II] were also recorded from HH 54. These observations are consistent with the concept of interstellar shock waves, but a quantitative unifying shock model, capable of explaining all observations, has yet to be developed.
