Timekeeping on Mars. (In red) Martian season lengths and time as compared to seasons on Earth (in blue), with marks for the vernal equinox, perihelion, and aphelion. Though no standard exists, numerous calendars and other timekeeping approaches have been proposed for the planet Mars.
Mars sol. Sol (borrowed from the Latin word for sun) is a solar day on Mars; that is, a Mars-day. A sol is the apparent interval between two successive returns of the Sun to the same meridian (sundial time) as seen by an observer on Mars. It is one of several units for timekeeping on Mars . A sol is slightly longer than an Earth day.
Darian calendar. The Darian calendar is a proposed system of timekeeping designed to serve the needs of any possible future human settlers on the planet Mars. It was created by aerospace engineer, political scientist, and space jurist Thomas Gangale in 1985 and named by him after his son Darius.
Perseverance, nicknamed Percy, [2] is a car -sized Mars rover designed to explore the Jezero crater on Mars as part of NASA 's Mars 2020 mission. It was manufactured by the Jet Propulsion Laboratory and launched on July 30, 2020, at 11:50 UTC. [3] Confirmation that the rover successfully landed on Mars was received on February 18, 2021, at 20: ...
Mars Year 1. Mars Year 1 is the first year of Martian timekeeping standard developed by Clancy et al. [1] originally for the purposes of working with the cyclical temporal variations of meteorological phenomena of Mars, but later used for general timekeeping on Mars. Mars Years have no officially adopted month systems.
The lowest energy transfer to Mars is a Hohmann transfer orbit, which would involve a roughly 9-month travel time from Earth to Mars, about 500 days (16 mo) [citation needed] at Mars to wait for the transfer window to Earth, and a travel time of about 9 months to return to Earth. This would be a 34-month trip.
The Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) was a technology demonstration on the NASA Mars 2020 rover Perseverance investigating the production of oxygen on Mars. On April 20, 2021, MOXIE produced oxygen from carbon dioxide in the Martian atmosphere by using solid oxide electrolysis .
Mars is the fourth planet from the Sun. The surface of Mars is orange-red because it is covered in iron (III) oxide dust, giving it the nickname " the Red Planet ". [21] [22] Mars is among the brightest objects in Earth's sky, and its high-contrast albedo features have made it a common subject for telescope viewing.
