A satellite goes around a planet. A probe goes "somewhere". A rover moves about on the surface of a planet.
Some probes currently on Mars include NASA's Perseverance rover, which landed in February 2021, and the Curiosity rover, which has been exploring the planet since August 2012. Another probe is NASA's InSight lander, which landed on Mars in November 2018 to study the planet's geology and seismic activity.
its long but here it isï‚· 1860s J.K. Starley sets up business in Coventry.Starley starts to manufacture sewing machines in the Coventry area. ï‚· 1884 Rover 'Safety' cycles are introduced.Starley introduces early tricycles and bicycles, using the name 'Rover' for the very first time. The Rover 'Safety' tricycle is followed by the Rover 'Safety' bicycle. The Rover 'Safety' was a forerunner of the modern pedal bicycle, and the name 'Rover' continues to mean 'bike' in Poland. ï‚· 1888 Rover Electric Carriage developed.Starley creates Coventry's first 'car' - an electric tricycle which is never developed beyond the prototype stage. ï‚· 1896 Company becomes Rover Cycle Company Limited.The Rover name is well established, and the company is renamed. ï‚· 1904 Rover stars to build its first car. ï‚· 1906 Production switches to cars only.Bicycle production stops, and the company is renamed to Rover Company Limited. ï‚· 1920s-30s Growth and Depression.By 1920, Rover has established itself as one of Britain's important car manufacturers. Growth levelled out during the 1920s, and Rover suffers badly from the Depression in the 1930s. ï‚· 1933 Spencer Wilks becomes Managing Director.Wilks starts to turn Rover around, and specialised in the production of prestige vehicles. Wilks also introduced a variety of systems to reduce work-in-progress - a forerunner of modern operations management principles. Spencer Wilks also appoints his brother, Maurice, to the design department. ï‚· 1937-1945 Rover factories work on War Effort.The Rover factories at Acocks Green and Solihull become a part of the Government's Shadow Factories scheme and build a variety of war parts including engines for aircraft and tanks. After the end of World War 2, demand continues for the Rolls Royce V12 Meteor tank engines, which continue to be manufactured at Acocks Green. Solihull begins to prepare to manufacture cars again with plans to manufacture 20,000 cars per year. With a war-crippled economy, the Government demands products for exports and continues to control steel allocations due to short supplies. Rover is forced to drop their ambitious plans. ï‚· 1946 Maurice Wilks' Jeep needs replacing.Maurice Wilks had a farm on Anglesey that made use of a beaten-up war surplus Willys Jeep. He found this Jeep useful for a variety of practical farm uses. Nearing the end of its life, Maurice was considering a replacement. No British alternative existed, and parts for a new Willys Jeep were hard to get at that time. What spares were available, had to be purchased as bulk war surplus stock. This problem identified a gap in the market for a farm vehicle that was smaller than a tractor but was more versatile, and was rugged without being cumbersome. ï‚· September 1947 The 'Land Rover' project was made official.Board Meeting minutes describe it as "the all-purpose vehicle on the lines of the Willys-Overland post-war Jeep was the most desirable" using the P3 engine, gearbox, and back axle.In reality the first prototypes were already running, with design work starting in spring 1947. ï‚· April 1948 Land Rover appears at Amsterdam Motor Show.Development of the Land Rover progressed quickly. The P6 engine proved to be too small, and a 1.6 litre engine is fitted instead. Two prototype 80-inch wheelbase Land Rovers are exhibited at the Amsterdam Motor Show. The new vehicle is greeted with enthusiasm, and was eaten up by the motoring press. ï‚· 1951 Land Rovers out-sell all other Rover vehicles 2 to 1. ï‚· 1954 86" and 107" Land Rovers introduced.During the 1950s, the wheelbase expands to 86" and larger engines are fitted. A long wheelbase 107" vehicle is introduced with a station wagon body. A diesel option is also introduced at about the same time. ï‚· 1958 Series II introduced.The Series II introduces the familiar barrel-sided body to the Land Rover range. The 4 cylinder 2,286cc engine is also introduced. Wheelbase options are 88in and 109in. Synchromesh is added to the top two gears. ï‚· 1961 Series IIA is introduced.This provided a diesel engine with a 2,286cc capacity to match the petrol option. ï‚· 1962 12-seater Station Wagon, and Series IIA Forward Control introduced.A 12-seater station wagon body is introduced for tax reasons. Fitting 12 adults into this vehicle was a tight squeeze.The first Forward Control vehicle is introduced. Intended as a robust load carrier, this positioned the cab above the engine. ï‚· 1966 Series IIB Forward Control is introduced.Due to required chassis strengthening, the IIA Forward Control is too heavy for the 4 cylinder petrol engine; and a 6 cylinder petrol engine is fitted. Heavy duty axles and larger tyres are also fitted. A diesel option was also available. The 6 cylinder petrol engine becomes an option on the standard 109" Land Rover from 1967. ï‚· 1967 Rover and Leyland merge.Rover and Leyland merge, with Leyland becoming the majority partner. ï‚· 1968 1 ton model introduced. Heavy duty '1 ton' version of the standard Series IIA 109" (3/4 ton) is introduced. ï‚· 1970 Range Rover launched.The Range Rover improves on the off-road capabilities of the Land Rover, whilst introducing the comforts and styling normally found on cars. Coil springs are introduced for the first time. ï‚· 1971 Series III launched.Replacing the Series IIA, the Series III included a number of refinements such as synchromesh on all high-box gears. Externally, it looks very similar to the classic IIA except for the grille and headlights. ï‚· 1972 Forward Control 101"A V8-powered Forward Control is introduced and sells well to the military. Unfortunately, it proves too utilitarian for civilian markets, and it remains a military-only vehicle. ï‚· 1976 One Millionth Land Rover is produced. ï‚· 1979 Stage One 109" V8 introduced.A new development programme begins to bear fruit with a V8-engined 109" Land Rover dubbed the "Stage One". Essentially a Series III, this had a grille flush with the wings to allow room for the larger engine. ï‚· 1983-84 90" and 110" vehicles launched.The venerable Series III is replaced by the 90" (1984) and 110" (1983) Land Rovers. These introduce modern styling, and coil springs. A 130in extra-long wheelbase version is also produced. ï‚· 1988 British Aerospace take over the Rover Group. ï‚· 1990 Discovery launched.The Discovery was aimed at the new family 4x4 market, but still had enviable off-road abilities. ï‚· 1990 90" and 110" vehicles rebranded as 'Defender'.In parallel to the launch of the Discovery, the 90" and 110" Land Rovers are rebranded under the 'Defender' name to reflect their use be defence forces. Rebranding is accompanied with a new 200TDi diesel engine option, with the 300TDi option following in 1993. ï‚· 1994 British Aerospace sell the Rover Group to BMW. ï‚· 1994 New Shape P38 Range Rover introduced.The Range Rover is completely re-modelled. The modern P38 Range Rover is aimed more at the on-road luxury SUV market, but is still a good off-road performer - unlike the bulk the competition. ï‚· 1996 Classic Range Rover ceases production.Production of the 'Classic' Range Rover continued in parallel to the P38, but finally cease in 1996. ï‚· 1997 Freelander introduced.The much rumoured CB40 project is revealed to the press as the Freelander. Designed to compete against small 4x4s such as the Honda CRV and Toyota RAV4, the Freelander departed from standard Land Rover design technologies, with a monocoque body and independent strut suspension. The Freelander quickly becomes Europe's best selling 4x4. ï‚· 1998 Discovery Series 2 launched.Remodelled Discovery Series 2, codename 'Tempest' is launched. ï‚· 2000 BMW sell Land Rover to Ford.BMW splits the Rover Group into two, selling Land Rover to Ford. The car division is sold to the British Phoenix management group. ï‚· 2002 Range Rover Mk III launched.The second major redesign of the Range Rover, is launched. ï‚· 2004 Discovery 3 launched.Discovery 3 is launched with a significant re-styling.
The purpose of a lander is to safely deliver a spacecraft or rover to the surface of a celestial body, such as a planet or moon, in order to conduct scientific experiments, research, or exploration. Landers are equipped with instruments and equipment to gather data and images from the surface.
The first successful fly-by of Mars was on July 14--15, 1965, by NASA's Mariner 4. On November 14, 1971 Mariner 9 became the first space probe to orbit another planet when it entered into orbit around Mars.The first objects to successfully land on the surface were two Soviet probes: Mars 2 on November 27 and Mars 3 on December 2, 1971, but both ceased communicating within seconds of landing. The 1975 NASA launches of the Viking program consisted of two orbiters, each having a lander; both landers successfully touched down in 1976. Viking 1 remained operational for six years, Viking 2 for three. The Viking landers relayed color panoramas of Mars and the orbiters mapped the surface so well that the images remain in use.The Soviet probes Phobos 1 and 2 were sent to Mars in 1988 to study Mars and its two moons. Phobos 1 lost contact on the way to Mars. Phobos 2, while successfully photographing Mars and Phobos, failed just before it was set to release two landers to the surface of Phobos.Following the 1992 failure of the Mars Observer orbiter, the NASA Mars Global Surveyor achieved Mars orbit in 1997. This mission was a complete success, having finished its primary mapping mission in early 2001. Contact was lost with the probe in November 2006 during its third extended program, spending exactly 10 operational years in space. The NASA Mars Pathfinder, carrying a robotic exploration vehicle Sojourner, landed in the Ares Vallis on Mars in the summer of 1997, returning many images.The NASA Phoenix Mars lander arrived on the north polar region of Mars on May 25, 2008. Its robotic arm was used to dig into the Martian soil and the presence of water ice was confirmed on June 20. The mission concluded on November 10, 2008 after contact was lost.The Dawn spacecraft flew by Mars in February 2009 for a gravity assist on its way to investigate Vesta and then Ceres.Spirit Rover (MER-A) was active from 2004 until 2010, when it stopped sending data.Current missionsThe NASA Mars Odyssey orbiter entered Mars orbit in 2001. Odyssey's Gamma Ray Spectrometer detected significant amounts of hydrogen in the upper metre or so of regolith on Mars. This hydrogen is thought to be contained in large deposits of water ice. The Mars Express mission of the European Space Agency (ESA) reached Mars in 2003. It carried the Beagle 2 lander, which failed during descent and was declared lost in February, 2004. In early 2004 the Planetary Fourier Spectrometer team announced the orbiter had detected methane in the Martian atmosphere. ESA announced in June 2006 the discovery of aurorae on Mars.In January 2004, the NASA twin Mars Exploration Rovers named Spirit (MER-A) and Opportunity (MER-B) landed on the surface of Mars. Both have met or exceeded all their targets. Among the most significant scientific returns has been conclusive evidence that liquid water existed at some time in the past at both landing sites. Martian dust devils and windstorms have occasionally cleaned both rovers' solar panels, and thus increased their lifespan.On March 10, 2006, the NASA Mars Reconnaissance Orbiter (MRO) probe arrived in orbit to conduct a two-year science survey. The orbiter will map the Martian terrain and weather to find suitable landing sites for upcoming lander missions. The MRO snapped the first image of a series of active avalanches near the planet's north pole, scientists said March 3, 2008.The joint Russian and Chinese Phobos-Grunt mission to return samples of the Martian moon, Phobos, launched in 2011. The spacecraft missed its opportunity to enter an orbit that would bring it to Mars, so it has failed its planned mission.En routeThe Mars Science Laboratory, named Curiosity, launched on 26 November, 2011, and plans reach Mars in August 2012. It is larger and more advanced than the Mars Exploration Rovers, with a movement rate of 90 m/h. Experiments include a laser chemical sampler that can deduce the make-up of rocks at a distance of 13 m. Future missionsIn 2008, NASA announced MAVEN, a robotic mission in 2013 to provide information about the atmosphere of Mars. In 2018 the ESA plans to launch its first Rover to Mars; the ExoMars rover will be capable of drilling 2 m into the soil in search of organic molecules. The Finnish-Russian MetNet, is mission concept where multiple small vehicles on Mars to establish a widespread observation network to investigate the planet's atmospheric structure, physics and meteorology. MetNet was considered for a piggyback launch on the Russian Phobos-Grunt mission, but not selected.
Mars rovers have tested for a variety of different things on Mars, and wih an array of instruments. The most well known tool used is the Pancam, (a panoramic camera) which allows people to view the surface by means of video. Other instruments include spectromers (instruments that determine the chemical composition of a substance by measuring the intensity of the light it gives off when burned), and drills which allow the rovers to test substances below the surface. Each of these instruments has been... instrumental... in the search for life on Mars.

It is a Mars rover.
The Mercury Messenger is an orbiting space probe observing the planet Mercury. We generally reserve the word "rover" for a tracked or wheeled vehicle which moves around on the surface, and we haven't tried to do that yet.
A rover simply roves and explores a planet and is designed to move across the surface of a planet or other astronomical body. and a probe is like a missile and gets shot out of the earths atmosphere very very fast and when is up in space takes photos and sends them back to earth, kind of like the Hubble Space Telescope (HST).
