Hubble Cycle 18 Proposal Selection

The TAC and panels recommended using less than 1.5% of the available orbits for observations by NICMOS. This indicates that NICMOS still provides unique scientific capabilities on Hubble; however, those programs represent a small contribution to the overall science program. Given these circumstances, and because the restart of the NICMOS cooling system requires resources—including a significant number of orbits—the Hubble project, the Institute, and NASA Headquarters agreed that NICMOS would not be available for science in Cycle 18. Consequently, no new NICMOS observations were approved.
