Navcam, short for navigational camera, is a type of camera found on certain robotic rovers or spacecraft used for navigation without interfering with scientific instruments. [1] [2] [3] Navcams typically take wide angle photographs that are used to plan the next moves of the vehicle [4] or object tracking. [1]

Overview

The Mars 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 stereoscopic 3-D imagery. [5] These cameras, like those on the Mars Pathfinder missions support use of the ICER image compression format[ citation needed ].

European Space Agency Rosetta spacecraft used a single camera with 5 degree field of view and 12 bit 1024x1024px resolution allowing for visual tracking on each of spacecraft approaches to the asteroids and finally the comet. [1]

<i>2001 Mars Odyssey</i> NASA orbiter for geology and hydrology

2001 Mars Odyssey is a robotic spacecraft orbiting the planet Mars. The project was developed by NASA, and contracted out to Lockheed Martin, with an expected cost for the entire mission of US$297 million. Its mission is to use spectrometers and a thermal imager to detect evidence of past or present water and ice, as well as study the planet's geology and radiation environment. It is hoped that the data Odyssey obtains will help answer the question of whether life existed on Mars and create a risk-assessment of the radiation that future astronauts on Mars might experience. It also acts as a relay for communications between the Curiosity rover, and previously the Mars Exploration Rovers and Phoenix lander, to Earth. The mission was named as a tribute to Arthur C. Clarke, evoking the name of his and Stanley Kubrick's 1968 film 2001: A Space Odyssey.

<span class="mw-page-title-main">Mars Exploration Rover</span> NASA mission to explore Mars via two rovers (Spirit and Opportunity); launched in 2003

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.

<i>Opportunity</i> (rover) NASA Mars rover deployed in 2004

Opportunity, also known as MER-B or MER-1, is a robotic rover that was active on Mars from 2004 until 2018. Opportunity was operational on Mars for 5111 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, Spirit functioned until it got stuck in 2009 and ceased communications in 2010, while Opportunity was able to stay operational for 5111 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 14 years, 47 days. By June 10, 2018, when it last contacted NASA, the rover had traveled a distance of 45.16 kilometers.

<span class="mw-page-title-main">Mars rover</span> Robotic vehicle for Mars surface exploration

A Mars rover is a motor vehicle designed to travel on the surface of Mars. Rovers have several advantages over stationary landers: they examine more territory, they can be directed to interesting features, they can place themselves in sunny positions to weather winter months, and they can advance the knowledge of how to perform very remote robotic vehicle control. They serve a different purpose than orbital spacecraft like Mars Reconnaissance Orbiter. A more recent development is the Mars helicopter.

<i>Mars Reconnaissance Orbiter</i> NASA Mars orbiter launched in 2005, still operational

Mars Reconnaissance Orbiter (MRO) is a spacecraft designed to search for the existence of water on Mars, as part of NASA's Mars Exploration Program. It was launched from Cape Canaveral on August 12, 2005, at 11:43 UTC and reached Mars on March 10, 2006, at 21:24 UTC. In November 2006, after six months of aerobraking, it entered its final science orbit and began its primary science phase.

<span class="mw-page-title-main">Mars Science Laboratory</span> Robotic mission that deployed the Curiosity rover to Mars in 2012

Mars Science Laboratory (MSL) is a robotic space probe mission to Mars launched by NASA on November 26, 2011, which successfully landed Curiosity, a Mars rover, in Gale Crater on August 6, 2012. The overall objectives include investigating Mars' habitability, studying its climate and geology, and collecting data for a human mission to Mars. The rover carries a variety of scientific instruments designed by an international team.

Maestro (software) was a free program released by NASA to allow users to view photos and daily progress of the Spirit and Opportunity rovers. It served as an activity planner for Mars that utilized a combination of 2D and 3D visuals to track the movement and missions of the Spirit and Opportunity rovers in 2004.

The MarsDial is a sundial that was devised for missions to Mars. It is used to calibrate the Pancam cameras of the Mars landers. MarsDials were placed on the Spirit and Opportunity Mars rovers, inscribed with the words "Two worlds, One sun" and the word "Mars" in 22 languages. The MarsDial can function as a gnomon, the stick or other vertical part of a sundial. The length and direction of the shadow cast by the stick allows observers to calculate the time of day. The sundial can also be used to tell which way is North, and to overcome the limitations of a magnetic north different from a true north.
