Extra-close oppositions of Mars happen every 15 to 17 years, when we pass between Mars and the Sun around the time of its perihelion (closest point to the Sun in orbit). The minimum distance between Earth and Mars has been declining over the years, and in 2003 the minimum distance was 55.76 million km, nearer than any such encounter in almost ...
Mars 2, Mars 3 and Mariner 9 were all launched into space in May 1971, and all entered Mars’ orbit that same year. NASA's Mariner 9 reached the planet's orbit first on November 14, narrowly beating the Soviet's spacecraft amid the space race , and subsequently became the first spacecraft to orbit another planet.
The juxtaposition of the heavens (al-samāʾ; pl. al-samāwāt) and the earth (al-arḍ; not in the plural form in the Qurʾān) is seen in 222 qurʾānic verses. The heavens and the earth are the most vital elements on the scene—in terms of occurrence and emphasis—compared to which all other elements lose importance, and around which all ...
Deimos (/ ˈ d aɪ m ə s /; systematic designation: Mars II) [11] is the smaller and outer of the two natural satellites of Mars, the other being Phobos. Deimos has a mean radius of 6.2 km (3.9 mi) and takes 30.3 hours to orbit Mars. [5] Deimos is 23,460 km (14,580 mi) from Mars, much farther than Mars's other moon, Phobos. [12]

Mars orbit insertion profile. The plan was for an insertion into Mars orbit on 24 September 2014, [10] [104] approximately 2 days after the arrival of NASA's MAVEN orbiter. [105] The 440-newton liquid apogee motor was test fired on 22 September at 09:00 UTC for 3.968 seconds, about 41 hours before actual orbit insertion. [104] [106] [107]
The fate of Mars Climate Orbiter (1999) is unknown, but it is thought to have burnt up in the atmosphere before impacting. Mariner 9, which entered Mars orbit in 1971, is expected to remain in orbit until approximately 2022, when the spacecraft is projected to enter the Martian atmosphere and either burn up or crash into the planet's surface.

An areostationary orbit, areosynchronous equatorial orbit (AEO), or Mars geostationary orbit is a circular areosynchronous orbit (ASO) approximately 17,032 km (10,583 mi) in altitude above the Mars equator and following the direction of Mars's rotation. An object in such an orbit has an orbital period equal to Mars's rotational period, and so ...
