Example of the Scale of the Cost Risk to NAIC

Cost per observing hour at Arecibo:
(a) Science observations are scheduled on the Arecibo telescope approximately 75% of the clock time (rest is maintenance, tests, etc)
(b) Radio astronomy observations are assigned approximately 75% of the time used for science observations
0 Radio astronomy observations are scheduled for ~4500 hours per year at Arecibo
(c) NAIC receives ~$9M per year from NSF/Astronomy to support the radio astronomy program at Arecibo
0 Cost per observing hour: $9M/4500 = $2k/hr
(d) A 1000 hour Survey observation is “worth” $2M.
