Mars comes closer to Earth more than any other planet save Venus at its nearest—56 million km is the closest distance between Mars and Earth, whereas the closest Venus comes to Earth is 40 million km. Mars comes closest to Earth every other year, around the time of its opposition, when Earth is sweeping between the Sun and Mars. Extra-close ...
This system is also much more precise: while the Mars Exploration Rovers could have landed anywhere within their respective 93-mile by 12-mile (150 by 20 kilometer) landing ellipses, Mars Science Laboratory landed within a 12-mile (20-kilometer) ellipse. [7] Mars 2020 has even more precise system, and landing ellipse of 7.7 by 6.6 km. [8]

A taxi would need to accelerate to 15,000 miles per hour (6.7 km/s) around Earth, and 22,000 miles per hour (9.8 km/s) near Mars. To get around this, Aldrin proposed what he called a semi-cycler, in which the castle would slow down around Mars, orbiting it, and later resume the cycler orbit. This would require fuel to execute the braking and re ...
It orbits Mars much faster than Mars rotates and completes an orbit in just 7 hours and 39 minutes. As a result, from the surface of Mars it appears to rise in the west, move across the sky in 4 hours and 15 minutes or less, and set in the east, twice each Martian day.
Mach speed on Mars is 546.4 miles per hour (879.3 km/h) at "sea level", so cruising speed would be around 130 miles per hour (210 km/h) at elevation. [ 5 ] In January 2024, MAGGIE was one of thirteen proposals approved for Phase 1 funding by the NIAC .
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". [22] [23] 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.
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]
