Satellite

In the context of spaceflight, a satellite is an artificial object which has been intentionally placed into orbit. Such objects are sometimes called artificial satellites to distinguish them from natural satellites such as Earth's Moon.

The world's first artificial satellite, the Sputnik 1, was launched by the Soviet Union in 1957. Since then, thousands of satellites have been launched into orbit around the Earth. Some satellites, notably space stations, have been launched in parts and assembled in orbit. Artificial satellites originate from more than 40 countries and have used the satellite launching capabilities of ten nations. About a thousand satellites are currently operational, whereas thousands of unused satellites and satellite fragments orbit the Earth as space debris. A few space probes have been placed into orbit around other bodies and become artificial satellites to the Moon, Mercury, Venus, Mars, Jupiter, Saturn, Vesta, Eros, Ceres, and the Sun.

Satellites are used for a large number of purposes. Common types include military and civilian Earth observation satellites, communications satellites, navigation satellites, weather satellites, and research satellites. Space stations and human spacecraft in orbit are also satellites. Satellite orbits vary greatly, depending on the purpose of the satellite, and are classified in a number of ways. Well-known (overlapping) classes include low Earth orbit, polar orbit, and geostationary orbit.

Satellite (software)

In computing, Red Hat Satellite, an open-source systems-management application, allows system administrators to deploy, manage and monitor Red Hat Enterprise Linux and Solaris hosts. One can think of Satellite as a local version of Red Hat Network.

An organisation's Satellite server registers with Red Hat Network and downloads relevant software into Satellite's software channels. The organisation's hosts then register against the local Satellite server, instead of directly against Red Hat Network.

This allows the organisation to control which versions of software it makes available for its hosts, as well as making additional software within the local network.

Recent versions of Red Hat Satellite emphasise virtualization and add features, particularly XML-RPC API features for deploying and managing virtual hosts.

Deploy

Satellite offers numerous methods for deploying hosts, including simple kickstart, bare metal install and re-imaging. Current versions of Satellite support kickstart using Cobbler as an underlying framework. PXE Boot, and Koan are methods that can be used to implement bare metal installs and re-imaging of hosts.

On Through the Night

On Through the Night is the debut album by English rock band Def Leppard, released in 1980. The album was produced by Tom Allom. It charted at No. 15 on the UK Albums Chart and No. 51 on the Billboard 200. The album features re-recorded versions of "Rocks Off" and "Overture", tracks from the band's original independently released EP, The Def Leppard E.P. Other tracks are re-recorded versions of early demos, some of which appeared on the First Strike and Warchild bootlegs. The album was certified platinum by the RIAA on 9 May 1989.

"Rocks Off", "Wasted", "Hello America" and "Rock Brigade" were released as singles. However, the versions of "Rocks Off" (titled "Getcha Rocks Off") and "Wasted" that appears on the singles is a different recording from that of the LP, as is its B-side, "Hello America". The single "Getcha Rocks Off" included the songs "Ride into the Sun" and "Overture".

Reception

Carriers (film)

Carriers is a 2009 American post-apocalyptic horror film written and directed by Àlex and David Pastor. It stars Lou Taylor Pucci, Chris Pine, Piper Perabo and Emily VanCamp as four people fleeing a viral pandemic.

Plot

An infectious virus has spread worldwide, killing almost the entire population - this disease is spread by breath. Two brothers, Brian and Daniel "Danny" Green, along with Brian's girlfriend, Bobby, and Danny's school friend, Kate, are heading to Turtle Beach in the Southwestern United States, a secluded beach motel where they believe they can wait for the viral pandemic to die out and so they can start a new life. They strictly follow a set of rules that they believe will keep them all alive and stop them from becoming infected.

On their way there, they meet a man, Frank Holloway, and his infected young daughter Jodie, who are stranded in the middle of a deserted road due to their Suburban running out of fuel. After attempting to drive away from them, their car breaks down. The four end up returning to Frank in order to acquire his Chevrolet Suburban, and are forced to take Frank and Jodie to a nearby high school where a serum for the pandemic is rumored to have been developed. Upon arrival they discover that the serum does not work, and the only doctor still alive is about to commit suicide with a remaining group of infected children (whom he plans to kill through non-voluntary euthanasia). Meanwhile, Bobby is accidentally infected by Jodie while trying to help her when she coughs blood on her. She hides her infection from the others by wiping her face and hiding her blood covered shirt. Jodie tells her father that she needs the toilet, however she can't walk there alone due to the illness. Frank carries Jodie to the toilet, telling Danny that he knows he's a good person. However, Brian leaves Frank and Jodie behind and takes their car.
