><i>Except for the hardware which was too large for the Shuttle, which was carried up by the Russian Proton booster.</i><p>The only modules which were too massive for Shuttle to lift to ISS were Zarya and Zvezda. These modules are about 2,540 and 2,270kg too heavy for Shuttle. However, it's worth noting that even with Proton's lift capacity they had to launch them partially equipped and mount a Shuttle mission to complete the outfitting. That Shuttle mission (2A.2 if memory serves correctly) also carried several tons of supplies.<p>There's no reason to doubt that the modules could have been designed to launch on Shuttle (ie in a more 'stripped' configuration) and outfitted by a third Shuttle mission.</p></p>
