Two missions, "side by side". One rotation clockwise, the other
anti-clockwise. Both satellites to have dishes of equal size and
separation, that point *away* from the Sun, even if
non-functional. I concern myself with a hot body, that has a
distinct and separate "solar sail" (aka antenna) that will be at
a temperature between that of the body and that of the CMBR...
providing Sun-directed net thrust from the power source. Heat is
also momentum.

But I think it is a waste of money.
