Choosing Mars time: analysis of the Mars Exploration Rover experience
Open accessAbstract
This paper focuses on the Mars Exploration Rover (MER) mission's management decision to work on Mars time and the implications of that decision on the tactical surface operations process as personnel planned activities and created a new command load for work on each Martian sol. The paper also looks at tools that supported the complexities of Mars time operations, and makes some comparisons between Earth and Mars time scheduling

One main challenge for future Mars missions will be synchronizing the circadian clock to a Martian day of 24.65 h.
“Regarding Mars, one main challenge will consist in synchronizing the circadian clock to a Martian day (24.65 h).”
From Sleep disruption, use of sleep-promoting medication and circadian desynchronization in spaceflight crewmembers: Evidence in low-Earth orbit and concerns for future deep-space exploration missions (2023) · cites this paper as [17]
The Introduction says a Martian day is 39 minutes longer than an Earth day, consistent with approximately 24.65 hours. The paper describes difficulties for Mars Exploration Rover personnel working on a shifting Mars-time schedule, including fatigue and recovery from shifts, but does not identify synchronizing the biological circadian clock as a main challenge for future missions. (LLM, conf=0.82)
Experimental — accuracy not yet measuredMars days (Sols) last 24 h 39 min, which is 3% more than Earth days.
“It is well known that Mars days (also called Sols) last 24 h, 39 min. This is 3% more than Earth days [17].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
