We formulated a gravity unloading strategy for a monolithic silicon carbide (SiC) mirror with a $\Phi {3}\,\rm m$ aperture in space. Employing the finite element analysis (FEA) technique, a rapid solution analytical approach for determining optimal support forces during gravity unloading is introduced. This method demonstrates enhanced efficiency and accuracy compared to conventional approaches.
