The average duration of the day-night cycle on Mars — i.e., a Martian day — is 24 hours, 39 minutes and 35.244 seconds, [3] equivalent to 1.02749125 Earth days. [4] The sidereal rotational period of Mars—its rotation compared to the fixed stars—is 24 hours, 37 minutes and 22.66 seconds. [4]
The game is set on a fictional Mars colony - the so-called "Dark Colony" - in the year 2137. Humans have discovered a "remarkable energy source" by the name of Petra-7 on the red planet. Figuring they'd rather not choke on the atmosphere of Mars whilst mining Petra-7, the Humans begin terraforming the planet. At the start of the game the ...
A circadian rhythm (/ s ər ˈ k eɪ d i ə n /), or circadian cycle, is a natural oscillation that repeats roughly every 24 hours.Circadian rhythms can refer to any process that originates within an organism (i.e., endogenous) and responds to the environment (is entrained by the environment).
For the Mars Pathfinder, Mars Exploration Rover (MER), Phoenix, and Mars Science Laboratory missions, the operations teams have worked on "Mars time", with a work schedule synchronized to the local time at the landing site on Mars, rather than the Earth day. This results in the crew's schedule sliding approximately 40 minutes later in Earth ...

Mars and Jupiter are cozying up in the night sky for their closest rendezvous this decade. In reality, our solar system’s biggest planet and its dimmer, reddish neighbor will be more than 350 ...
In vertebrates, the master circadian clock is contained within the suprachiasmatic nucleus (SCN), a bilateral nerve cluster of about 20,000 neurons. [10] [11] The SCN itself is located in the hypothalamus, a small region of the brain situated directly above the optic chiasm, where it receives input from specialized photosensitive ganglion cells in the retina via the retinohypothalamic tract.
NASA explored the potential impact on circadian rhythm and possible development of a sleep–wake disorder by human astronauts who would go on a mission to Mars, by assessing mission personnel who worked remotely on the Phoenix Mars Lander project and were asked to follow a Mars day of 24.65 hours for 78 days.
