    NICMOS was installed on Hubble during its second servicing mission in 1997 along with the Space Telescope Imaging Spectrograph, replacing two earlier instruments.. NICMOS in turn has been largely superseded by the Wide Field Camera 3, which has a much larger field of view (135 by 127 arcsec, or 2.3 by 2.1 arcminutes), and reaches almost as far into the in
