Israel is developing a space payload for UV astronomy. The experiment was proposed by a team of scientists for Tel Aviv University and was studied in Phase A with a team of engineers for El-Op. The payload consists of three coaligned telescopes with 20 cm apertures. The same sky area of about 2 deg is imaged by the three telescopes onto image-counting detectors. Each telescope is tuned to a different spectral band of about 400 A width between 1400 A and 2800 A. The main scientific aim of this mission is to survey a large area of the sky in the UV. Photometry in three UV bands, when combined with optical photometry from the ground, permits the separation of quasars from foreground stars. The wide field of view allows complete surveys of large angular size nearby galaxies and of entire clusters of galaxies. In addition, properties of complete stellar populations, e.g., white dwarfs, mixed-type binaries, can be studied. The UV imaging payload may serve as pathfinder for more elaborate space astronomy experiments, such as the Hubble Space Telescope.
