Mars Orbit Rendezvous
Mars orbit rendezvous (MOR) is a space travel concept where two spacecraft meet up and/or dock in Mars orbit. Overview For example, one vehicle takes off from Mars, such as a Martian ascent stage, and does a rendezvous in Mars orbit with another spacecraft. Applied to a Mars sample return or human mission to Mars, it allows much less weight to be sent to the surface and back into orbit, because the fuel needed to travel back to Earth is not landed on the planet.

Mars Orbit Rendez Vous S95 01407
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, only being larger than Mercury. In the English language, Mars is named for the Roman god of war. Mars is a terrestrial planet with a thin atmosphere (less than 1% that of Earth's), and has a crust primarily composed of elements similar to Earth's crust, as well as a core made of iron and nickel. Mars has surface features such as impact craters, valleys, dunes and polar ice caps. It has two small and irregularly shaped moons, Phobos and Deimos. Some of the most notable surface features on Mars include Olympus Mons, the largest volcano and highest known mountain in the Solar System and Valles Marineris, one of the largest canyons in the Solar System. The Borealis basin in the Northern Hemisphere covers approximately 40% of the planet and may be a large impact feature. Days and seasons on Mars are comparable to those of Earth, as the planets have a similar rotation period and tilt o ...
