Brave New World? Service Mode...

To observe with a telescope is not exactly what it has been. Not so long ago, the astronomer worked next to the telescope, pushed the buttons, watched the sky through the dome slit and entertained the night assistant with his personal repertoire of songs, frequently ranging from the tragedy of Tosca to the invocative expressions of "Let it be, let it be" or even later masterpieces.

Nowadays, however, in the Age of Automation, the "observer" sits in a brightly lit room, somewhere in the telescope building (he is not quite sure where), and punches the keys of a computer console. He does not know where the telescope is (it may be in space) nor has he any idea of how it looks like. He only worries about the 1/2 night that has been allocated by the Observing Programmes Committee (OPC) for his observations and whether the telescope and the weather will permit him to obtain the data he has been waiting for during the past year with so much expectation.

The present trend is towards even more automation, even better efficiency, etc. What will it be like, 5 years from now? Always ahead of its time, THE MESSENGER has obtained a listing of a future file in the central ESO/La Silla Computer system which is reproduced in facsimile here and illustrated by Karen Saxby. For convenience of the reader, the central computer is indicated by a dash (-) and the observing astronomer with a colon (:).
