Actually, the Hansen's left in 2354, as can be seen in this log entry.

I've argued on the talk page for the Raven (linked to above) that the image should not be taken as canonical, as the text doesn't mention the Raven but a ship called the Jefferies, it only states that the ship only left the Drexler outpost in 2354 (and there's no indication that this outpost was the beginning point of the journey) and clearly spoken dialogue between Seven and janeway indicate a different time frame. Unless there is any canonical evidence to support a 2354 departure (which I do not believe that the graphic is), I really do believe that a 2353 departure is more accurate.--Tiberius 01:58, 16 January 2007 (UTC)
Well, graphics are considered canon on MA... however, as a policy, what was said in dialogue tends to take precedence over production graphics. --From Andoria with Love 03:53, 16 January 2007 (UTC)
You support altering the entry then?--Tiberius 06:17, 19 January 2007 (UTC)
Sure. Just be sure to note as background info that the graphic says 2354. :) --From Andoria with Love 18:52, 19 January 2007 (UTC)
