If humanity were exploring the galaxy why would people pay for surveys of barren lumps of ice? They'd be interested in planets which were resource rich and/or potentially capable of sustaining life. Explorers focus on points of potential interest, Scott and Amundsen didn't pause to look at every crevasse, ridgeline or snowflake on the way to the pole.
Well lumps of ice no.. but some barren planets could be mineral rich, or contain important metalsmetaln space you need to mmetals much as possible.
But this is a game we are talking about, not real life.
