<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">nasa launch</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for rocket that I've seen before include "Projectile lettuce" , "Firework - salad plant" , "cylinder full of inflammable material" , "Severe reprimand" , "Self-propelled missile and a plant" .)
