Galaxion is a web comic sci-fi story that was a traditional comic series in the 90’s and is now being remade as a web comic (I believe we are past the end of the original comic). The story is about a large yacht that is being used by a exportation agency (TerSA, think NASA with the budget of the US navy). They are the testbed for a new FTL drive system.
They already have a FTL system. Its just not very efficient. Months to the far colonies, entire colonies almost died from starvation because they were unable to get the word out about emergencies soon enough.
The first use of this new drive blew a ship up. The second almost blew the ship up and did set it on fire. The second use however did send them what would normally be three months of travel in less then five minuets. After they went over the data from the second attempt they realized they needed a very large engine room. This is why the Galaxion was chosen, it has a disproportionately large engine room (thanks to it being a former yacht).
The overall story resembles a disaster story in that they are reacting to things beyond their full control, and trying to understand things very fast. It maintains a very good sense of urgency that helps the story move very nicely.
The science is good. While certainly not hard core hard sci-fi the author does have a good grasp on physics and such, as you can see when disasters strike. You also get the idea that he has a lot more built and understood then he puts to paper (always a good sign).
The characterization is good. It will get you in the feels when people are hurt or killed (yes that will happen). The art is more then enough to help this along. The creator is more then capable of telling a story with a few dialog free frames. From the very first page the art is professional, without being sterile or lacking personality.
I will say however that between updating only on Tuesdays and the large cast of characters it can get hard to keep track, which is why I go back and reread it every so often.
