First and foremost: power. Solar power requires that the solar arrays be directed toward the sun. Losing attitude control means that they&amp;#x27;ll lose efficiency and thus power. This isn&amp;#x27;t a big deal in the short run, but long term is a big deal. Surely they&amp;#x27;ll have this fixed before that comes into play.&lt;p&gt;Aside from that, there&amp;#x27;s a lot of other smaller factors such as being able to orient the station to boost orbit every so often. Even though they&amp;#x27;re in Low Earth Orbit, there is a &lt;i&gt;just&lt;/i&gt; enough atmosphere to cause the orbit to decay slightly over time, and this has to be compensated for by boosting the orbit. No attitude control = no orienting thrusters.&lt;p&gt;Obligatory Scott Manley video that&amp;#x27;s way better than what I just said:
