McCool Hill
McCool Hill is the tallest of the Columbia Hills (Mars), Columbia Hills in Gusev (crater on Mars), Gusev crater, Mars. It was named in honor of William C. McCool, an astronaut of the Space Shuttle Columbia, Space Shuttle ''Columbia'' during its final mission where it disintegrated during atmospheric reentry (see Space Shuttle Columbia disaster, Space Shuttle ''Columbia'' disaster). The hill was to be Spirit rover, ''Spirit'' rover's next target. She was expected to reach significant north-facing slopes on the hill in mid-April 2006, and spend her second winter on Mars there. However, on the way to the slopes on "McCool Hill" between outcrops nicknamed Hermann Oberth, "Oberth" and Sergei Korolev, "Korolev," ''Spirit'' ran into an impassable sandy area. To increase solar power output, ''Spirit''s handlers redirected the rover to a closer north-facing slope in an area known as "Low Ridge" or "Low Ridge Haven," about 20 meters away from the rover's position on sol 802 (April 5, 2006) ...

Husband Hill
Husband Hill is one of the Columbia Hills in Gusev crater, Mars, which are close to the landing site of NASA's ''Spirit'' rover. It was named in honor of Rick Husband, the commander of the Space Shuttle ''Columbia'' when it disintegrated upon atmospheric reentry (see Space Shuttle ''Columbia'' disaster). In 2005, the ''Spirit'' rover, as part of its exploration of its landing site, slowly climbed to the top of Husband Hill. It reached the summit on August 21, 2005, and began its descent on September 25, 2005, after spending nearly two months examining the outcrops and views of the summit plateau before moving on. Named areas on the hill include the " Cumberland Ridge", where rocks with higher than normal phosphorus Phosphorus is a chemical element with the symbol P and atomic number 15. Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on Ear ... content exi ...

Columbia Hills (Mars)
The Columbia Hills are a range of low hills inside Gusev crater on Mars. They were observed by the Mars Exploration Rover ''Spirit'' when it landed within the crater in 2004. They were promptly given an unofficial name by NASA since they were the most striking nearby feature on the surface. The hills lie approximately away from the rover's original landing position. The range is named to memorialize the Space Shuttle ''Columbia'' disaster. On February 2, 2004, the individual peaks of the Columbia Hills were named after the seven astronauts who died in the disaster. ''Spirit'' spent a few years exploring the Columbia Hills until it ceased to function in 2010. It was also considered a potential landing site for the Mars 2020 ''Perseverance'' rover, before the selection of Jezero crater in November 2018. Peaks The seven peaks are, from north to south: * Anderson Hill - named after Michael P. Anderson * Brown Hill - named after David M. Brown * Chawla Hill - named after Kalpana ...

Gusev (crater On Mars)
Gusev is a Impact crater, crater on the planet Mars and is located at and is in the Aeolis quadrangle. The crater is about 166 kilometers in diameter and formed approximately three to four billion years ago. It was named after Russian astronomer Matvey Gusev (1826–1866) in 1976. Prior to the exploration of the crater by the Spirit Rover, the crater was postulated to be an ancient lakebed with Ma'adim Vallis draining into it, of volcaniclastic origin, or a combination of both. These interpretations were based on ''Viking'' orbiter imagery, Mars Orbiter Camera, MOC imagery, Thermal Emission Imaging System, THEMIS thermal mapping, and Mars Orbiter Laser Altimeter, MOLA elevation mapping. However, Spirit did not find any lacustrine deposits, instead Spirit found alkaline volcanic rocks, including olivine basalt, comminution, comminuted basaltic debris, lavas, and pyroclastic rocks, but no eruption centers. More recently, satellite images showed the trails of dust devils on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mars
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, only being larger than Mercury (planet), Mercury. In the English language, Mars is named for the Mars (mythology), 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 (moon), Phobos and Deimos (moon), Deimos. Some of the most notable surface features on Mars include Olympus Mons, the largest volcano and List of tallest mountains in the Solar System, highest known mountain in the Solar System and Valles Marineris, one of the largest canyons in the Solar System. The North Polar Basin (Mars), Borealis basin in the Northern Hemisphere covers approximately 40% of the planet and may be a la ...

Astronaut
An astronaut (from the Ancient Greek (), meaning 'star', and (), meaning 'sailor') is a person trained, equipped, and deployed by a human spaceflight program to serve as a commander or crew member aboard a spacecraft. Although generally reserved for professional space travelers, the term is sometimes applied to anyone who travels into space, including scientists, politicians, journalists, and tourists. "Astronaut" technically applies to all human space travelers regardless of nationality. However, astronauts fielded by Russia or the Soviet Union are typically known instead as cosmonauts (from the Russian "kosmos" (космос), meaning "space", also borrowed from Greek). Comparatively recent developments in crewed spaceflight made by China have led to the rise of the term taikonaut (from the Mandarin "tàikōng" (), meaning "space"), although its use is somewhat informal and its origin is unclear. In China, the People's Liberation Army Astronaut Corps astronauts and their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Space Shuttle Columbia
Space Shuttle ''Columbia'' (OV-102) was a Space Shuttle orbiter manufactured by Rockwell International and operated by NASA. Named after the Columbia Rediviva, first American ship to circumnavigate the upper North American Pacific coast and the Columbia (personification), female personification of the United States, ''Columbia'' was the first of five Space Shuttle orbiters to fly in space, debuting the Space Shuttle, Space Shuttle launch vehicle on STS-1, its maiden flight in April 1981. As only the second full-scale orbiter to be manufactured after the Approach and Landing Tests, Approach and Landing Test vehicle ''Space Shuttle Enterprise, Enterprise'', ''Columbia'' retained unique features indicative of its experimental design compared to later orbiters, such as test instrumentation and distinctive black Chine (aeronautics), chines. In addition to a heavier fuselage and the retention of an internal airlock throughout its lifetime, these made ''Columbia'' the heaviest of the fi ...

Atmospheric Reentry
Atmospheric entry is the movement of an object from outer space into and through the gases of an atmosphere of a planet, dwarf planet, or natural satellite. There are two main types of atmospheric entry: ''uncontrolled entry'', such as the entry of astronomical objects, space debris, or bolides; and ''controlled entry'' (or ''reentry'') of a spacecraft capable of being navigated or following a predetermined course. Technologies and procedures allowing the controlled atmospheric ''entry, descent, and landing'' of spacecraft are collectively termed as ''EDL''. Objects entering an atmosphere experience atmospheric drag, which puts mechanical stress on the object, and aerodynamic heating—caused mostly by compression of the air in front of the object, but also by drag. These forces can cause loss of mass (ablation) or even complete disintegration of smaller objects, and objects with lower compressive strength can explode. Crewed space vehicles must be slowed to subsonic speeds be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Space Shuttle Columbia Disaster
The Space Shuttle ''Columbia'' disaster was a fatal accident in the United States space program that occurred on February 1, 2003. During the STS-107 mission, Space Shuttle ''Columbia'' disintegrated as it reentered the atmosphere over Texas, killing all seven astronauts on board. The mission was the second that ended in disaster in the Space Shuttle program after the loss of ''Challenger'' and all seven crew members during ascent in 1986. During the STS-107 launch, a piece of the insulative foam broke off from the Space Shuttle external tank and struck the thermal protection system tiles on the orbiter's left wing. Similar foam shedding had occurred during previous Space Shuttle launches, causing damage that ranged from minor to near-catastrophic, but some engineers suspected that the damage to ''Columbia'' was more serious. Before reentry, NASA managers had limited the investigation, reasoning that the crew could not have fixed the problem if it had been confirmed. When ' ...

Hermann Oberth
Hermann Julius Oberth (; 25 June 1894 – 28 December 1989) was an Austro-Hungarian-born German physicist and engineer. He is considered one of the founding fathers of rocketry and astronautics, along with Robert Esnault-Pelterie, Konstantin Tsiolkovsky, Robert Goddard and Herman Potočnik.During WWII he supported Nazi Germany's ''Aggregat'' rocket program. Early life Oberth was born to a Transylvanian Saxon family in Nagyszeben (Hermannstadt), Austrian-Hungary Empire (today Sibiu in Romania). He was fluent in Romanian language. At the age of 11 years, Oberth's interest in rocketry was set off by the novels of Jules Verne, especially ''From the Earth to the Moon'' and ''Around the Moon''. He was fond of reading them over and over until they were engraved in his memory. As a result, Oberth constructed his first model rocket as a school student at the age of 14. In his youthful experiments, he arrived independently at the concept of the multistage rocket. However, during this ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
