Proposals for use of the Hubble Space Telescope (HST) are due October 1, 1988, according to a statement from the Space Telescope Science Institute in Baltimore, Md. The cutoff date has been moved forward during the past year because of rescheduling of Space Shuttle launches.

The telescope, which will allow scientists to peer deep into space without Earth's atmosphere in the way, is in line to be carried into orbit by the shuttle in June 1989. Observing proposals submitted by the deadline will be considered for the General Observer program for the period December 1989–November 1990.
