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 ...
Mars's average distance from the Sun is roughly 230 million km (143 million mi), and its orbital period is 687 (Earth) days. The solar day (or sol ) on Mars is only slightly longer than an Earth day: 24 hours, 39 minutes, and 35.244 seconds. [ 185 ]
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]
2001 Mars Odyssey is a robotic spacecraft orbiting the planet Mars. The project was developed by NASA , and contracted out to Lockheed Martin , with an expected cost for the entire mission of US$297 million.
The satellites of Mars include : Non functional but (probably) orbiting: Viking 1 & 2 orbiter; Mariner 9; Mars Global Surveyor; Mars 2, 3, 5; Phobos 2;
Besides decaying to Mars, a collision with a moon or other spacecraft is also a possibility. [12] In March 2017, MAVEN had to change its orbit to avoid colliding with Phobos, and with an increasing number of spacecraft at Mars this risk increases. [13] The Mars Global Surveyor is still being tracked, although it is no longer functioning. [14]
The Mars One Project is a privately-funded mission that will take 100 people to live on the Red Planet starting in 2026. ... How one man feels about his wife moving to Mars. Mary Kinney.
MOLA topographic images of the two hemispheres of Mars. This image appeared on the cover of Science magazine in May 1999. The Mars Orbiter Laser Altimeter (MOLA) was one of five instruments on the Mars Global Surveyor (MGS) spacecraft, which operated in Mars orbit from September 1997 to November 2006. However, the MOLA instrument transmitted ...
