Eumetsat
The European Organization for the Exploitation of Meteorological Satellites (EUMETSAT) is an intergovernmental organisation created through an international convention agreed by a current total of 30 European Member States. EUMETSAT's primary objective is to establish, maintain and exploit European systems of operational meteorological satellites. EUMETSAT is responsible for the launch and operation of the satellites and for delivering satellite data to end-users as well as contributing to the operational monitoring of climate and the detection of global climate changes. The activities of EUMETSAT contribute to a global meteorological satellite observing system coordinated with other space-faring nations. Satellite observations are an essential input to numerical weather prediction systems and also assist the human forecaster in the diagnosis of potentially hazardous weather developments. Of growing importance is the capacity of weather satellites to gather long-term measurem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Budget Sequestration In 2013
The 2013 budget sequestration refers to the automatic spending cuts to United States federal government spending in particular categories of outlays that were initially set to begin on January 1, 2013, as a fiscal policy as a result of Budget Control Act of 2011 (BCA), and were postponed by two months by the American Taxpayer Relief Act of 2012 until March 1 when this law went into effect. The reductions in spending authority were approximately $85.4 billion (versus a reduction of $42 billion in actual cash outlays) during fiscal year 2013, with similar cuts for years 2014 until 2021. However, the Congressional Budget Office estimated that the total federal outlays would continue to increase even with the sequester by an average of $238.6 billion per year during the following decade, although at a somewhat lesser rate. The cuts were split evenly (by dollar amounts, ''not'' by percentages) between the defense and non-defense categories. Some major programs like Social Securi ...

Space Weather
Space weather is a branch of space physics and aeronomy, or heliophysics, concerned with the time varying conditions within the Solar System, including the solar wind, emphasizing the space surrounding the Earth, including conditions in the magnetosphere, ionosphere, thermosphere, and exosphere. Space weather is distinct from, but conceptually related to, the terrestrial weather of the atmosphere of Earth ( troposphere and stratosphere). The term "space weather" was first used in the 1950s and came into common usage in the 1990s. Later, it was generalized to a " space climate" research discipline, which focuses on general behaviors of longer and larger-scale variabilities and effects. History For many centuries, the effects of space weather were noticed, but not understood. Displays of auroral light have long been observed at high latitudes. Genesis In 1724, George Graham reported that the needle of a magnetic compass was regularly deflected from magnetic north o ...

Kosmos 2251
Kosmos-2251 (russian: Космос-2251 meaning ''Cosmos 2251''), was a Russian Strela-2M military communications satellite. It was launched into Low Earth orbit from Site 132/1 at the Plesetsk Cosmodrome at 04:17 UTC on 16 June 1993, by a Kosmos-3M carrier rocket.· The Strela satellites had a lifespan of 5 years, and the Russian government reported that Kosmos-2251 ceased functioning in 1995. Russia was later criticised by ''The Space Review'' for leaving a defunct satellite in a congested orbit, rather than deorbiting it. In response, Russia noted that they were (and are) not required to do so under international law. In any case, the KAUR-1 satellites had no propulsion system, which is usually required for deorbiting. Destruction At 16:56 UTC on 10 February 2009, it collided with Iridium 33 (1997-051C), an Iridium satellite, in the first major collision of two satellites in Earth orbit. The Iridium satellite, which was operational at the time of the collision, was destro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
