  The Galileo spacecraft had distant encounters with Earth in 1990 and 1992.
Limited Solid State Imager (SSI) data acquired during these encounters has been
previously presented, but the majority of the data from these Earth flybys have
not been presented in the literature. Observations of Earth taken from afar are
both rare and directly relevant to the development of any future exo-Earth
direct imaging mission. Here we present a pipeline that vets, calibrates, and
measures the disk-integrated brightness of the Earth, in multiple filters, from
the complete SSI data sets from both the 1990 and 1992 Galileo flybys. The
result is over 1500 usable photometric measurements for Earth as an analog for
an exoplanet. The 1990 data set includes full rotational lightcurves in six
bandpasses spanning the optical range. The 1992 data set is more limited, with
lightcurves only spanning 14 hr. Time-averaged photometry for both encounters
is presented while variability and color are discussed relative to findings
from NASA's EPOXI mission (which also provided photometric lighturves for
Earth). The new Galileo/SSI data are used to further validate the Virtual
Planetary Laboratory 3D spectral Earth model, which often serves as a stand-in
for true disk-integrated observations of our planet. The revived Galileo/SSI
data for Earth is a testament to the ability of NASA's Planetary Data System to
maintain data over decades-long timescales. The disk-integrated products
derived from these data add to a very short list of calibrated and published
whole-disk observations of the Pale Blue Dot.
