behind 're-usable' is cutting costs on an xpensive and very high frequency launch program(say,weekly launch to maintain a lunar mining program..but precisely wat the hindus might not have). Xactly wat the US shuttle program was intended for but failed to accomplish; the expendable france/EU ariane 4 rocket was an effective competitor to the highly subsidized US shuttle program. Since a hindu 'space shuttle' is a hi profile program BR hindus can masturbate on, the hindu space agency has effectively found a new holy cow to milk for decades to come. Hail Bharat !
