Phobos Monolith
The Phobos monolith is a large rock on the surface of Mars's moon Phobos. It is a boulder about across and tall. A monolith is a geological feature consisting of a single massive piece of rock. Monoliths also occur naturally on Earth, but it has been suggested that the Phobos monolith may be a piece of impact ejecta. The monolith is a bright object near Stickney crater, described as a "building sized" boulder, which casts a prominent shadow.Optech press release,Canadian Mission Concept to Mysterious Mars moon Phobos to Feature Unique Rock-Dock Maneuver" 3 May 2007. It was discovered by Efrain Palermo, who did extensive surveys of Martian probe imagery, and later confirmed by Lan Fleming, an imaging sub-contractor at NASA Johnson Space Center. The general vicinity of the monolith is a proposed landing site by Optech and the Mars Institute, for a robotic mission to Phobos known as PRIME (Phobos Reconnaissance and International Mars Exploration). The PRIME mission would be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Space
Space is the boundless three-dimensional extent in which objects and events have relative position and direction. In classical physics, physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. Debates concerning the nature, essence and the mode of existence of space date back to antiquity; namely, to treatises like the ''Timaeus'' of Plato, or Socrates in his reflections on what the Greeks called ''khôra'' (i.e. "space"), or in the ''Physics'' of Aristotle (Book IV, Delta) in the definition of ''topos'' (i.e. place), or in the later "geometrical conception of place" as "spac ...

Libya Montes
The Libya Montes are a highland terrain on Mars up-lifted by the giant impact that created the Isidis basin to the north. During 1999, this region became one of the top two that were being considered for the canceled Mars Surveyor 2001 Lander. The Isidis basin is very ancient. Thus, the Libya Montes that form the southern Isidis basin rim contain some of the oldest rocks available at the Martian surface, and a landing in this region might potentially provide information about conditions on early Mars. After they formed by the Isidis impact, the Libya Montes were subsequently modified by a large variety of processes, including fluvial activity, wind erosion and impact cratering. In particular, precipitation induced surface runoff and groundwater seepage resulted in the formation of fluvial landforms, i.e., dense valley networks, broad and elongated valleys, delta deposits, alluvial fans, open-basin paleolakes and coastlines.

Cydonia (Mars)
Cydonia (, ) is a region on the planet Mars that has attracted both scientific and popular interest. The name originally referred to the albedo feature (distinctively coloured area) that was visible from earthbound telescopes. The area borders the plains of Acidalia Planitia and the highlands of Arabia Terra. The region includes the named features Cydonia Mensae, an area of flat-topped mesa-like features; Cydonia Colles, a region of small hills or Mountain, knobs; and Cydonia Labyrinthus, a complex of intersecting valleys. As with other albedo features on Mars, the name Cydonia was Classical albedo features on Mars#B-E, drawn from classical antiquity, in this case from ''Kydonia'' ( grc, Κυδωνία; lat, Cydonia), a historic ''polis'' (city state) on the island of Crete. Cydonia contains the "Face on Mars", located about halfway between the craters Arandas (crater), Arandas and Bamberg (crater), Bamberg. Location Cydonia lies in the planet's northern hemisphere in a transit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caves Of Mars Project
The Caves of Mars Project was an early 2000s program funded through Phase II by the NASA Institute for Advanced Concepts to assess the best place to situate the research and habitation modules that a human mission to Mars would require. The final report was published in mid 2004. Description Caves and other underground structures, including Martian lava tubes, canyon overhangs, and other Martian cavities would be potentially useful for crewed missions, for they would provide considerable shielding from both the elements and intense solar radiation to which a Mars mission would expose astronauts. They might also offer access to minerals, gases, ices, and any wiktionary:subterranean, subterranean life that the crew of such a mission would probably be searching for. The program also studied designs for inflatable modules and other such structures that would aid the astronauts to build a livable environment for humans and earth creatures.

Blue Remembered Earth
''Blue Remembered Earth'' is a science fiction novel by Welsh author Alastair Reynolds, first published by Gollancz on 19 January 2012. It describes the efforts of two adult siblings to solve a mystery in the pseudo-utopian 2160s. The novel is the first of the ''Poseidon's Children'' trilogy, which follows humanity's development over many centuries, with the intention of portraying a more optimistic future than anything Reynolds had previously written. The second book in the trilogy, '' On the Steel Breeze'', was released on 26 September 2013, and the trilogy's finale, '' Poseidon's Wake'', was released on 30 April 2015. Background Reynolds first announced his plans to write the ''Poseidon's Children'' trilogy (known at the time as the "11k" trilogy) in early 2009. He described the first novel of the series as featuring a utopian future where Africa is a leading technological power. ''Blue Remembered Earth'' was initially scheduled for publication in 2011, but was ultimately re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mars Monolith
The Mars monolith is a rectangular object (possibly a boulder) discovered on the surface of Mars. It is located near the bottom of a cliff, from which it likely fell. The Mars Reconnaissance Orbiter took pictures of it from orbit, roughly 180 miles (300 km) away. The HiRISE camera that was used to photograph the monolith has a resolution of approximately 1 foot or 30 centimeters per pixel. Around the same time, the Phobos monolith made international news.

Mars Global Surveyor
''Mars Global Surveyor'' (MGS) was an American robotic space probe developed by NASA's Jet Propulsion Laboratory and launched November 1996. MGS was a global mapping mission that examined the entire planet, from the ionosphere down through the atmosphere to the surface. As part of the larger Mars Exploration Program, Mars Global Surveyor performed atmospheric monitoring for sister orbiters during aerobraking, and helped Mars rovers and lander missions by identifying potential landing sites and relaying surface telemetry. It completed its primary mission in January 2001 and was in its third extended mission phase when, on 2 November 2006, the spacecraft failed to respond to messages and commands. A faint signal was detected three days later which indicated that it had gone into safe mode. Attempts to recontact the spacecraft and resolve the problem failed, and NASA officially ended the mission in January 2007. MGS remains in a stable near-polar circular orbit at about 450 km ...

Monolith Closeup
A monolith is a geological feature consisting of a single massive stone or rock, such as some mountains. For instance, Savandurga mountain is a monolith mountain in India. Erosion usually exposes the geological formations, which are often made of very hard and solid igneous or metamorphic rock. Some monoliths are volcanic plugs, solidified lava filling the vent of an extinct volcano. In architecture, the term has considerable overlap with megalith, which is normally used for prehistory, and may be used in the contexts of rock-cut architecture that remains attached to solid rock, as in monolithic church, or for exceptionally large stones such as obelisks, statues, monolithic columns or large architraves, that may have been moved a considerable distance after quarrying. It may also be used of large glacial erratics moved by natural forces. The word derives, via the Latin , from the Ancient Greek word (), from () meaning "one" or "single" and () meaning "stone".
