Sol (day On Mars)
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. It is approximately 24 hours, 39 minutes, 35 seconds long. A Timekeeping on Mars#Martian year, Martian year is approximately 668.6 sols, equivalent to approximately 687 Earth days or 1.88 Earth years. The sol was adopted in 1976 during the Viking program, Viking Lander missions and is a unit of measurement, measure of time mainly used by NASA when, for example, scheduling the use of a Mars rover. Length The average duration of the day-night cycle on Mars—i.e., a Martian day—is 24 hours, 39 minutes and 35.244 seconds, equivalent to 1.02749125 Earth days. The sidereal rotational period of Mars—its rotation compared to the fixed stars—is 24 hours, 37 m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mars Science Laboratory
Mars Science Laboratory (MSL) is a robotic spacecraft, robotic space probe mission to Mars launched by NASA on November 26, 2011, which successfully landed ''Curiosity (rover), Curiosity'', a Mars rover, in Gale (crater), Gale Crater on August 6, 2012. The overall objectives include investigating Mars' Planetary habitability, habitability, studying its Climate of Mars, climate and Planetary geology, geology, and collecting data for a human mission to Mars. The rover carries a variety of scientific instruments designed by an international team. Overview MSL carried out the most accurate Martian landing of any spacecraft at the time, hitting a target landing ellipse of , in the Aeolis Palus region of Gale Crater. MSL landed east and north of the center of the target. This location is near the mountain Aeolis Mons (a.k.a. "Mount Sharp").

Philip K
Philip, also Phillip, is a male name derived from the Macedonian Old Koine language, Greek (''Philippos'', lit. "horse-loving" or "fond of horses"), from a compound of (''philos'', "dear", "loved", "loving") and (''hippos'', "horse"). Prominent Philips who popularized the name include List of kings of Macedonia, kings of Macedonia and one of the apostles of early Christianity. ''Philip'' has #Philip in other languages, many alternative spellings. One derivation often used as a surname is Phillips (surname), Phillips. The original Greek spelling includes two Ps as seen in Philippides (other), Philippides and Philippos, which is possible due to the Greek endings following the two Ps. To end a word with such a double consonant—in Greek or in English—would, however, be incorrect. It has many diminutive (or even hypocorism, hypocoristic) forms including Phil, Philly (other)#People, Philly, Phillie, Lip (other), Lip, and Pip (other), Pip. There ...

Witching Hour (supernatural)
In folklore, the witching hour or devil's hour is a time of night that is associated with supernatural events, whereby witches, demons and ghosts are thought to appear and be at their most powerful. Definitions vary, and include the hour immediately after midnight and the time between 3:00am and 4:00am. The term now has a widespread colloquial and idiomatic usage that is associated with human physiology and behaviour to more superstitious phenomena, such as luck. Origins The phrase "witching hour" began at least as early as 1762, when it appeared in Elizabeth Carolina Keene's ''Miscellaneous Poems''. It alludes to Hamlet's line "Tis now the very witching time of night, When Churchyards yawne, and hell it selfe breakes out Contagion to this world." Time There are multiple times that can be considered the witching hour. Some claim the time is between 12:00 am and 1:00 am, while others claim there is increased supernatural activity between sunset and sunrise. The '' New Zealand O ...

Midnight
Midnight is the transition time from one day to the next – the moment when the date changes, on the local official clock time for any particular jurisdiction. By clock time, midnight is the opposite of noon, differing from it by 12 hours. Solar midnight is the time antisolar point, opposite to solar noon, when the Sun is meridian (astronomy), closest to the nadir, and the night is culmination, equidistant from sunset and sunrise. Due to the advent of time zones, which regularize time across a range of meridian (geography), meridians, and daylight saving time, solar midnight rarely coincides with 12 midnight on the clock. Solar midnight depends on longitude and time of the year rather than on time zone. In ancient Roman timekeeping, midnight was halfway between dusk and dawn (i.e., solar midnight), varying according to the seasons. In some Slavic languages, "midnight" has an additional geographic association with "north" (as "noon" does with "south"). Modern Polish languag ...

Colonization (British English: colonisation) is a process of establishing occupation of or control over foreign territories or peoples for the purpose of cultivation, exploitation, trade and possibly settlement, setting up coloniality and often colonies. Colonization is commonly pursued and maintained by, but distinct from, imperialism, mercantilism, or colonialism.

Opportunity (rover)
''Opportunity'', also known as MER-B (Mars Exploration Rover – B) or MER-1, and nicknamed Oppy, is a robotic rover that was active on Mars from 2004 until 2018. ''Opportunity'' was operational on Mars for sols ( on Earth). Launched on July 7, 2003, as part of NASA's Mars Exploration Rover program, it landed in Meridiani Planum on January 25, 2004, three weeks after its twin, '' Spirit'' (MER-A), touched down on the other side of the planet. With a planned 90- sol duration of activity (slightly less than 92.5 Earth days), ''Spirit'' functioned until it got stuck in 2009 and ceased communications in 2010, while ''Opportunity'' was able to stay operational for sols after landing, maintaining its power and key systems through continual recharging of its batteries using solar power, and hibernating during events such as dust storms to save power. This careful operation allowed ''Opportunity'' to operate for 57 times its designed lifespan, exceeding the initial plan by (in Ear ...

Spirit (rover)
''Spirit'', also known as MER-A (Mars Exploration Rover – A) or MER-2, is a Mars rover, Mars robotic rover, active from 2004 to 2010. ''Spirit'' was operational on Mars for Timekeeping on Mars#Sols, sols or 3.3 Martian years ( days; '). It was one of two rover (space exploration), rovers of NASA's Mars Exploration Rover Mission managed by the Jet Propulsion Laboratory (JPL). Spirit landed successfully within the impact crater Gusev (Martian crater), Gusev on Mars at 04:35 Ground UTC on January 4, 2004, three weeks before its twin, ''Opportunity (rover), Opportunity'' (MER-B), which landed on the other side of the planet. Its name was chosen through a Sofi Collis, NASA-sponsored student essay competition. The rover got stuck in a "sand trap" in late 2009 at an angle that hampered recharging of its batteries; its last communication with Earth was on March 22, 2010.
