Without SM4 and the installation of new Ni-HB2B batteries, HST is facing a future with decreasing battery capacity. This ISR explores one option for reducing HST’s battery load during orbit night while maintaining the science capability of the NICMOS. Modulating the NCS setpoint temperature, i.e., increasing it during orbit night and decreasing it during orbit day, can accomplish this. A linear NICMOS small ΔT thermal model was developed based on flight data serendipitously obtained during Proposal 10097, NICMOS Temperature Setpoint Darks, to predict camera one’s temperature, NCS compressor speed, and total NCS power for modulations of +/-1, +/-2, and +/-3K. The results are presented.
