Please explain why, if your story tells of how an astronaut survives on an alien planet, that narration should feel like a to-do list? There will be intense emotions (shock at discovering what happened, fear of death, hope shattered, despair, hope regained), there will be dramatic turns of events (solutions he attempts will almost seem to work only to fail at the last moment), there will be interesting and exotic environments (spaceship, alien planet, future technology). Why should any of this feel mundane and commonplace?
Your story could become boring if you plan to structure your narration like a full recording of everything that happens. Your question seems to indicate that you may plan to dedicate one section of your comic to each 14.8 hour cycle and have the same fixed number of pages for each of these "days". That may indeed turn your story into a long and potentially boring list of things your astronaut does, because not every hour of every day might be equally interesting.
Usually the story structure follows the demands of the story, not the other way around. Most narrations skip much of what happens and only tell the interesting parts. The common everyday parts like sleeping are usually left for the audience to supplement in their minds, and uneventful passages are usually briefly summarized ("Three weeks later..."). On the other hand, what may be mundane to the person doing it may be interesting to the readers. For example, how bushmen sleep (with their upper bodies propped up on their arms so insects don't crawl in their ears) or using a toilet in zero gravity might be banal to the person doing it but worth showing to your readers.
The everyday life of an astronaut surviving on an alien planet is potentionally interesting enough in and of itself not to become boring even if you recount it in its minutiae.
Maybe you should read some tales of survival to understand how these kinds of stories work. I recommend The Martian by Andy Weir, of course, but also Pincher Martin by William Golding.
