Phobos is the innermost and larger of the two natural satellites of Mars, the other being Deimos. The two moons were discovered in 1877 by American astronomer Asaph Hall. Phobos is named after the Greek god of fear and panic, who is the son of Ares (Mars) and twin brother of Deimos.
Deimos 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. Deimos is 23,460 km (14,580 mi) from Mars, much farther than Mars's other moon, Phobos. It is named after Deimos, the Ancient Greek god and personification of dread and terror.
The Mars trilogy is a series of science fiction novels by Kim Stanley Robinson that chronicles the settlement and terraforming of the planet Mars through the personal and detailed viewpoints of a wide variety of characters spanning almost two centuries. The events of the book span from 2026 to 2212, approximately more than 187 years. Ultimately more utopian than dystopian, the story focuses on egalitarian, sociological, and scientific advances made on Mars, while Earth suffers from overpopulation and ecological disaster.
The Martian Manhunter is a superhero in American comic books published by DC Comics. Created by writer Joseph Samachson and artist Joe Certa, the character first appeared in the story "The Manhunter from Mars" in Detective Comics #225. Martian Manhunter is one of the seven original members of the Justice League of America and one of the most powerful beings in the DC Universe.
The planet Mars has been explored remotely by spacecraft. Probes sent from Earth, beginning in the late 20th century, have yielded a large increase in knowledge about the Martian system, focused primarily on understanding its geology and habitability potential. Engineering interplanetary journeys is complicated and the exploration of Mars has experienced a high failure rate, especially the early attempts. Roughly sixty percent of all spacecraft destined for Mars failed before completing their missions, with some failing before their observations could begin. Some missions have been met with unexpected success, such as the twin Mars Exploration Rovers, Spirit and Opportunity, which operated for years beyond their specification.
Leather Goddesses of Phobos is an interactive fiction video game written by Steve Meretzky and published by Infocom in 1986. It was released for the Amiga, Amstrad CPC, Amstrad PCW, Apple II, Mac, Atari 8-bit computers, Atari ST, Commodore 64, TI-99/4A, and MS-DOS. The game was Infocom's first "sex farce", including selectable gender and "naughtiness"—the latter ranging from "tame" to "lewd". It was one of five top-selling Infocom titles to be re-released in Solid Gold versions. It was Infocom's twenty-first game.
Fobos-Grunt or Phobos-Grunt was an attempted Russian sample return mission to Phobos, one of the moons of Mars. Fobos-Grunt also carried the Chinese Mars orbiter Yinghuo-1 and the tiny Living Interplanetary Flight Experiment funded by the Planetary Society.
The Sands of Mars is a science fiction novel by English writer Arthur C. Clarke. While he was already popular as a short story writer and as a magazine contributor, The Sands of Mars was also a prelude to Clarke's becoming one of the world's foremost writers of science fiction novels. The story was published in 1951, before humans had achieved space flight. It is set principally on the planet Mars, which has been settled by humans and is used essentially as a research establishment. The story setting is that Mars has been surveyed but not fully explored on the ground. The Sands of Mars was Clarke's first published novel.
In the colonization of Mars humans would inhabit Martian territory and exploit resources there, possibly enabling the settlement of Mars. Most Mars colonization concepts focus on settling, but colonization is a broader ethical concept, which international space law has limited, and national space programs have avoided, instead focusing on human missions to Mars for exploring the planet. Exploitation of native resources might include in situ resource utilization to produce consumables like propellants and life support gasses which would otherwise need to be imported from Earth. Currently there are only proposals for Mars colonization and no humans have yet lived on or visited Mars.
Many astronomical phenomena viewed from the planet Mars are the same as or similar to those seen from Earth; but some are quite different. For example, because the atmosphere of Mars does not contain an ozone layer, it is also possible to make UV observations from the surface of Mars.
The idea of sending humans to Mars has been the subject of aerospace engineering and scientific studies since the late 1940s as part of the broader exploration of Mars. Long-term proposals have included sending settlers and terraforming the planet. Currently, only robotic landers and rovers have been on Mars. The farthest humans have been beyond Earth is the Moon, under the U.S. National Aeronautics and Space Administration (NASA) Apollo program which ended in 1972.
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". 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. It is classified as a terrestrial planet and is the second smallest of the Solar System's planets with a diameter of 6,779 km (4,212 mi). In terms of orbital motion, a Martian solar day (sol) is equal to 24.5 hours, and a Martian solar year is equal to 1.88 Earth years. Mars has two natural satellites that are small and irregular in shape: Phobos and Deimos.
Mars MetNet was a planned atmospheric science mission to Mars, initiated by the Finnish Meteorological Institute (FMI) together with Russia and Spain. By September 2013, two flight-capable entry, descent and landing systems (EDLS) have been manufactured and tested. As of 2015 baseline funding exists until 2020. As of 2016, neither the launch vehicle nor precursory launch date have been set.
Interplanetary contamination refers to biological contamination of a planetary body by a space probe or spacecraft, either deliberate or unintentional.
The War of the Worlds is a science fiction novel by English author H. G. Wells. It was written between 1895 and 1897, and serialised in Pearson's Magazine in the UK and Cosmopolitan magazine in the US in 1897. The full novel was first published in hardcover in 1898 by William Heinemann. The War of the Worlds is one of the earliest stories to detail a conflict between humankind and an extraterrestrial race. The novel is the first-person narrative of an unnamed protagonist in Surrey and his younger brother who escapes to Tillingham in Essex as London and Southern England are invaded by Martians. It is one of the most commented-on works in the science fiction canon.
Phobos Surveyor is a mission concept under preliminary study by Marco Pavone of Stanford University, the NASA Jet Propulsion Laboratory (JPL), and the Massachusetts Institute of Technology as a part of NASA's Innovative Advanced Concepts program.
The Asteroid Redirect Mission (ARM), also known as the Asteroid Retrieval and Utilization (ARU) mission and the Asteroid Initiative, was a space mission proposed by NASA in 2013; the mission was later cancelled. The Asteroid Retrieval Robotic Mission (ARRM) spacecraft would rendezvous with a large near-Earth asteroid and use robotic arms with anchoring grippers to retrieve a 4-meter boulder from the asteroid.
Phobos And Deimos & Mars Environment (PADME) is a low-cost NASA Mars orbiter mission concept that would address longstanding unknowns about Mars' two moons Phobos and Deimos and their environment.
Martian Moons eXploration (MMX) is a robotic space probe set for launch in 2026 to bring back the first samples from Mars' largest moon Phobos. Developed by the Japan Aerospace Exploration Agency (JAXA) and announced on 9 June 2015, MMX will land and collect samples from Phobos once or twice, along with conducting Deimos flyby observations and monitoring Mars's climate.
