A rover (or sometimes planetary rover) is a space exploration vehicle designed to move across the surface of a planet or other celestial body. Some rovers have been designed to transport members of a human spaceflight crew; others have been partially or fully autonomous robots. Rovers usually arrive at the planetary surface on a lander-style spacecraft.
Rovers have several advantages over stationary landers: they examine more territory and they can be directed to interesting features. If they are solar powered, they can place themselves in sunny positions to weather winter months. They can also advance the knowledge of how to perform very remote robotic vehicle control which is necessarily semi-autonomous due to the finite speed of light.
Their advantages over orbiting spacecraft are that they can make observations to a microscopic level and can conduct physical experimentation. Disadvantages of rovers compared to orbiters are the higher chance of failure, due to landing and other risks, and that they are limited to a small area around a landing site which itself is only approximately anticipated.
Rover or rovers may refer to:
A rover is a bus or train ticket in the United Kingdom that allows unlimited travel on any operating company over a set route, for a certain period of time, at certain times.
It differs from a ranger ticket, that allows unlimited travel on one operating company over a set route, for a certain period of time, at certain times.
Lunar Jim is an animated preschool-oriented stop-motion television show produced in Canada by Halifax Film and Alliance Atlantis, and aired in the USA as well on Discovery Channel and V-Me from 2003-2012. The show is based on an original concept created by Alexander Bar. Season 1 was Executive Produced by Jeff Rosen. It was script-edited in Season one by Peter Sauder. Season two was helmed by award-winning veteran producer/writer Jed MacKay. Ben Zelkowicz provided the voice of Jim.
Jim and his team; Rover the Robot Dog, Ripple the Super Space Mechanic, Eco the Farmer, and TED, the Technical Equipment Device, live on Blue Moon L22, the second-to-last moon on the edge of the Milky Way. Focusing on exploration and inquiry, Lunar Jim intends to promote such life skills as problem-solving, persistence, creativity, and cooperation, with an emphasis on "pre-science skills". His rallying cry is "Let's get lunar!"
Space is an album by American jazz group the Modern Jazz Quartet featuring performances recorded in 1969 and released on the Apple label.
The Allmusic review stated "Overall this is an average but worthy outing from a group whose excellence could always be taken for granted".
All compositions by John Lewis, except where noted.
In mathematics, four-dimensional space ("4D") is a geometric space with four dimensions. It typically is more specifically four-dimensional Euclidean space, generalizing the rules of three-dimensional Euclidean space. It has been studied by mathematicians and philosophers for over two centuries, both for its own interest and for the insights it offered into mathematics and related fields.
Algebraically, it is generated by applying the rules of vectors and coordinate geometry to a space with four dimensions. In particular a vector with four elements (a 4-tuple) can be used to represent a position in four-dimensional space. The space is a Euclidean space, so has a metric and norm, and so all directions are treated as the same: the additional dimension is indistinguishable from the other three.
In modern physics, space and time are unified in a four-dimensional Minkowski continuum called spacetime, whose metric treats the time dimension differently from the three spatial dimensions (see below for the definition of the Minkowski metric/pairing). Spacetime is not a Euclidean space.
The Grand Theft Auto V soundtrack, like previous games in the Grand Theft Auto series, features various radio stations that play different genres of music when the player enters vehicles in the game. The stations consist of licensed music, DJ chat and spoof advertising. The game features 18 in-game stations with 240 licensed songs, 16 of which are musical stations and the other two are talk stations.
Since the game's location is modelled on southern California, the developers attempted to create an accurate representation of Californian music. Production of the soundtrack also consisted of licensing music for the radio stations, and selecting a DJ that matches the genre of music the station hosts. The soundtrack consists of a wide variety of radio stations that play different genres of music, including reggae, hip hop, pop and country. The game also features an original and dynamic score composed by Tangerine Dream, Woody Jackson, Alchemist and Oh No which plays out in several selective missions. Selected tracks from the score were later released on The Music of Grand Theft Auto V. In September 2014, it was announced that new songs would be added to some of the radio stations in the next-gen releases of the game.
