Mars Exploration Rovers
NASA's Mars Exploration Rover (MER) mission was a robotic space mission involving two Mars rovers, ''Spirit'' and ''Opportunity'', exploring the planet Mars. It began in 2003 with the launch of the two rovers to explore the Martian surface and geology; both landed on Mars at separate locations in January 2004. Both rovers far outlived their planned missions of 90 Martian solar days: MER-A ''Spirit'' was active until March 22, 2010, while MER-B ''Opportunity'' was active until June 10, 2018. Objectives The mission's scientific objective was to search for and characterize a wide range of rocks and soils that hold clues to past water activity on Mars. The mission is part of NASA's Mars Exploration Program, which includes three previous successful landers: the two Viking program landers in 1976 and Mars Pathfinder probe in 1997. The total cost of building, launching, landing and operating the rovers on the surface for the initial 90- sol primary mission was US$820 million. ...

Spirit (rover)
''Spirit'', also known as MER-A (Mars Exploration Rover – A) or MER-2, is a Mars Rover, Mars robotic rover, active from 2004 to 2010. ''Spirit'' was operational on Mars for Timekeeping on Mars#Sols, sols or 3.3 Martian years ( days; '). It was one of two rover (space exploration), rovers of NASA's Mars Exploration Rover Mission managed by the Jet Propulsion Laboratory (JPL). Spirit landed successfully within the impact crater Gusev (Martian crater), Gusev on Mars at 04:35 Ground UTC on January 4, 2004, three weeks before its twin, ''Opportunity (rover), Opportunity'' (MER-B), which landed on the other side of the planet. Its name was chosen through a Sofi Collis, NASA-sponsored student essay competition. The rover got stuck in a "sand trap" in late 2009 at an angle that hampered recharging of its batteries; its last communication with Earth was on March 22, 2010. The rover completed its planned 90-Martian day, sol mission (slightly less than 92.5 Earth days). Aided by cleani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Opportunity (rover)
''Opportunity'', also known as MER-B (Mars Exploration Rover – B) or MER-1, is a robotic rover that was active on Mars from 2004 until 2018. ''Opportunity'' was operational on Mars for sols (). Launched on July 7, 2003, as part of NASA's Mars Exploration Rover program, it landed in Meridiani Planum on January 25, 2004, three weeks after its twin, ''Spirit'' (MER-A), touched down on the other side of the planet. With a planned 90- sol duration of activity (slightly less than 92.5 Earth days), ''Spirit'' functioned until it got stuck in 2009 and ceased communications in 2010, while ''Opportunity'' was able to stay operational for sols after landing, maintaining its power and key systems through continual recharging of its batteries using solar power, and hibernating during events such as dust storms to save power. This careful operation allowed ''Opportunity'' to operate for 57 times its designed lifespan, exceeding the initial plan by (in Earth time). By June 10, 2018, when ...

Navcam
Navcam, short for navigational camera, is a type of camera found on certain robotic rover (space exploration), rovers or spacecraft used for navigation without interfering with scientific instruments. Navcams typically take wide angle photographs that are used to plan the next moves of the vehicle or object tracking. Overview The Mars Curiosity rover, ''Curiosity'' rover has two pairs of black and white navigation cameras mounted on the mast to support ground navigation. The cameras have a 45 degree angle of view and use visible light to capture Stereoscopy, stereoscopic 3-D imagery. These cameras, like those on the Mars Pathfinder missions support use of the ICER image compression format. European Space Agency Rosetta (spacecraft), ''Rosetta'' spacecraft used a single camera with 5 degree field of view and 12 Color depth, bit 1024x1024px resolution allowing for visual tracking on each of spacecraft approaches to the asteroids and finally the 67P/Churyumov–Gerasimenko, comet.

Mini-TES
The Miniature Thermal Emission Spectrometer (Mini-TES) is an infrared spectrometer used for detecting the composition of a material (typically rocks) from a distance. By making its measurements in the thermal infrared part of the electromagnetic spectrum, it has the ability to penetrate through the dust coatings common to the Martian surface which is usually problematic for remote sensing observations. There is one on each of the two Mars Exploration Rovers. Development The Mini-TES was originally developed by Raytheon for the Department of Geological Sciences at Arizona State University. The Mini-TES is a miniaturized version of Raytheon's Mars Global Surveyor (MGS) TES, built by Arizona State University and Raytheon SAS’ Santa Barbara Remote Sensing. The MGS TES data helped scientists choose landing sites for the Spirit and Opportunity Mars explorer rovers. Martian soil The Mini-TES is used for identifying promising rocks and soils for closer examination, and to determine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rosalind Franklin (rover)
''Rosalind Franklin'', previously known as the ExoMars rover, is a planned robotic Mars rover, part of the international ExoMars programme led by the European Space Agency and the Russian Roscosmos State Corporation. The mission was scheduled to launch in July 2020, but was postponed to 2022. The 2022 Russian invasion of Ukraine has caused an indefinite delay of the programme, as the member states of the ESA voted to suspend the joint mission with Russia; in July 2022, ESA terminated its cooperation on the project with Russia. As of May 2022, the launch of the rover is not expected to occur before 2028 due to the need for a new non-Russian landing platform. The original plan called for a Russian launch vehicle, an ESA carrier model, and a Russian lander named ''Kazachok'', that would deploy the rover to Mars' surface. Once it had safely landed, the Photovoltaics, solar powered rover would begin a seven-month (218-Timekeeping on Mars#Sols, sol) mission to search for the existenc ...

Astrionics
Astrionics is the science and technology of the development and application of electronic systems, subsystems, and components used in spacecraft. The electronic systems on-board a spacecraft are embedded systems and include attitude determination and control, communications, command and telemetry, and computer systems. Sensors refers to the electronic components on board a spacecraft. For engineers one of the most important considerations that must be made in the design process is the environment in which the spacecraft systems and components must operate and endure. The challenges of designing systems and components for the space environment include more than the fact that space is a vacuum. Attitude determination and control Overview One of the most vital roles electronics and sensors play in a mission and performance of a spacecraft is to determine and control its attitude, or how it is oriented in space. The orientation of a spacecraft varies depending on the mission. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
