SAC-B Solar Platform
Argentine thermal engineer Juan Bratina inspecting the SAC-B
satellite just prior to its insertion into the thermal vacuum
test chamber at INPE-LIT. This photo shows the solar platform
of the satellite, which is the side that will be pointed at
the Sun during flight. The cables attached to the solar platform
carry data signals during the thermal vacuum test (see below).
The white square object near the bottom of the solar platform with
the verticle and horizon slits is the fine Sun sensor, which is
used to keep the satellite's solar panels pointed at the Sun.
This side of the satellite also contains the Argentine HXRS
instrument and the US Goddard Space Flight Center's SOX instrument,
which are both designed to study X-rays from solar flares with
high time resolution.
