Cape York (Mars)
Cape York is a location on Mars, on the western rim of Endeavour crater. The ''Opportunity'' rover spent about two years exploring this portion of the rim in the early 2010s before moving south. The CRISM instrument on the ''Mars Reconnaissance Orbiter'' identified clay smectites in an area of Cape York, and the rover was sent to explore this location. MER-B ''Opportunity'' spend its fifth Martian Winter at Greeley Haven at Cape York, and also took a panorama at that location. MER-B spent 19 weeks stationed at Greeley Haven surviving the winter and went on the move again in May 2012, to further explore Cape York. MER-B arrived at Cape York in 2011 at Odyssey crater, which is on the southern end of the feature. ''Opportunity'' arrived at Endeavour crater on sol (August 9, 2011), at a landmark called ''Spirit Point'' named after its rover twin, after traversing from Victoria crater, over a three-year period. Spirit point was the name selected for where MER-B arrived at Endeavour ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MERB Sol3348 1
Merb is a discontinued model–view–controller web framework in Ruby, notable as a precursor to Rails 3. It brought increased focus on speed and modularity to Rails 3. The name Merb is a contraction of "Mongrel" and "Erb". Precursor to and merge with Rails 3 Merb began as a "clean-room" implementation of the Rails controller stack but grew to incorporate several ideas that deviated from Rails's spirit and methodology at the time, most notably component modularity, extensible API design, and vertical scalability. It was developed by Ezra Zygmuntowicz and Yehuda Katz. Most of these capabilities were added to Rails during the Rails 3/Merb merger. Merb was first released at the 2008 RubyConf and development has since stopped; Rails 3 ,therefore, serves as both the successor to Rails 2 and the successor to Merb. Differences from Ruby on Rails Merb's design attempted to address several criticisms of Rails 2: * lack of component modularity (monolithic design) * lack of an e ...

Surface Features Of Mars
A surface, as the term is most generally used, is the outermost or uppermost layer of a physical object or space. It is the portion or region of the object that can first be perceived by an observer using the senses of sight and touch, and is the portion with which other materials first interact. The surface of an object is more than "a mere geometric solid", but is "filled with, spread over by, or suffused with perceivable qualities such as color and warmth". The concept of surface has been abstracted and formalized in mathematics, specifically in geometry. Depending on the properties on which the emphasis is given, there are several non equivalent such formalizations, that are all called ''surface'', sometimes with some qualifier, such as algebraic surface, smooth surface or fractal surface. The concept of surface and its mathematical abstraction are both widely used in physics, engineering, computer graphics, and many other disciplines, primarily in representing the surfac ...

Exploration Of Mars
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 and some failed before their observations could begin. Some missions have met with unexpected success, such as the twin Mars Exploration Rovers, ''Spirit'' and ''Opportunity'' which operated for years beyond their specification. Current status , there are three operational rovers on the surface of Mars, the ''Curiosity'' and ''Perseverance'' rovers, both operated by the United States of America space agency NASA, as well as the ''Zhurong'' rover, part of the ''Tianwen-1'' mi ...

Solander Point
Solander Point is at the north end of the west-southwestern ridgeline of Endeavour crater on the planet Mars. It is named after the Swedish scientist Daniel Solander, who was the first university-educated scientist to set foot on Australian soil at Botany Bay in 1770. Solander Point was visited in 2013 by the Mars Exploration Rover-B ''Opportunity'', a robotic rover that was active on Mars from 2004-2018. By early July 2013 ''Opportunity'' was approaching it from the North, after previously examining outcrops on the northwest edge of the crater, north of Solander. The rover drove south from ''Cape York'' through ''Botany Bay'' to travel to Solander. By July 2, 2013, it was about half-way there. The area was imaged from Martian orbit by HiRISE on July 8, 2013, data which aids the rover team in understanding the terrain and planning rover traverses. The rover has been making good time on its approach to Solander, giving the opportunity to investigate a curious area of terrain in ...

__NOTOC__ Year 685 ( DCLXXXV) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar. The denomination 685 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Byzantine Empire * September – Emperor Constantine IV dies of dysentery at Constantinople after a 17-year reign, and is succeeded by his 16-year-old son Justinian II. Europe * Kuber, brother of Asparukh of Bulgaria, defeats the Avars in Syrmia (Pannonia). He leads his followers of around 70,000 people to Macedonia (modern North Macedonia). Britain * May 20 – Battle of Dun Nechtain: The Picts under King Bridei III revolt against their Northumbrian overlords. Cuthbert, bishop of Lindisfarne, advises King Ecgfrith of Northumbria (Bridei's cousin) not to invade Pictland (modern Scotland). Undeterred, Ecgfrith marches his army north to engage the ...
