Geomagnetic storm severity info (K-Index) NOAA / Space Weather Prediction Center The K-index is a code that is related to the maximum fluctuations of horizontal components observed on a magnetometer relative to a quiet day, during a three-hour interval. The conversion table from maximum fluctuation (nT) to K-index, varies from observatory to observatory in such a way that the historical rate of occurrence of certain levels of K are about the same at all observatories.
Colonization of the outer Solar System Many parts of the outer Solar System have been considered for possible future colonization. Most of the larger moons of the outer planets contain water ice, liquid water, and organic compounds that might be useful for sustaining human life.[1][2] Colonies in the outer Solar System could also serve as centers for long-term investigation of the planet and the other moons. In particular, robotic devices could be controlled by humans without the very long time delays needed to communicate with Earth.

Today's Space Weather The Satellite Environment Plot combines satellite and ground-based data to provide an overview of the current geosynchronous satellite environment. Click on a data panel to open an updating secondary window. An updating Satellite Environment Plot window is also available. Although these data are of interest to the satellite community, they do not include all parameters and energy ranges known to be associated with satellite anomalies. PHILOSOPHICAL ANTHROPOLOGY: Earth Under Fire - Galactic Superwaves Lagonisi, Greece August 2009 Dr Paul LaViolette is the measured counterpart to Patrick Geryl, whose interview we have released simultaneously. A brilliant and maverick astrophysicist, Paul is best known for his research into a new theory of matter he calls Subquantum Kinetics - based on systems theory, which he studied for his PhD thesis - and for his carefully argued hypothesis, first formulated in 1983, that our galactic center periodically emits devastating waves he termed Superwaves. Galactic Superwaves are intense cosmic ray particle bombardments that originate from the center of our Galaxy, and that last for periods of up to a few thousand years.
The Sun l Sun Facts and images. Our Sun is a normal main-sequence G2 star, one of more than 100 billion stars in our galaxy. diameter: 1,390,000 km. mass: 1.989e30 kgtemperature: 5800 K (surface) 15,600,000 K (core) History of The Sun The Sun is by far the largest object in the solar system. It contains more than 99.8% of the total mass of the Solar System (Jupiter contains most of the rest). It is often said that the Sun is an "ordinary" star.
Russia Orders Obama: Tell World About Aliens, Or We Will A stunning Ministry of Foreign Affairs (MFA) report on Prime Minister Medvedev’s [photo top right] agenda at the World Economic Forum (WEF) this week states that Russia will warn President Obama that the “time has come” for the world to know the truth about aliens, and if the United States won’t participate in the announcement, the Kremlin will do so on its own. The WEF (The Forum) is a Swiss non-profit foundation, based in Cologny, Geneva and describes itself as an independent international organization committed to improving the state of the world by engaging business, political, academic and other leaders of society to shape global, regional and industry agendas. The Forum is best known for its annual meeting in Davos, a mountain resort in Graubünden, in the eastern Alps region of Switzerland. “Along with the briefcase with nuclear codes, the president of the country is given a special ‘top secret’ folder.
Geospatial intelligence Geospatial intelligence, GEOINT (GEOspatial INTelligence), GeoIntel (Geospatial Intelligence), or GSI (GeoSpatial Intelligence) is intelligence about the human activity on earth derived from the exploitation and analysis of imagery and geospatial information that describes, assesses, and visually depicts physical features and geographically referenced activities on the Earth. GEOINT consists of imagery, imagery intelligence (IMINT) and geospatial information.[1] Amplified definition[edit] GEOINT encompasses all aspects of imagery (including capabilities formerly referred to as Advanced Geospatial Intelligence and imagery-derived MASINT) and geospatial information and services (GI&S); formerly referred to as mapping, charting, and geodesy). Geospatial data, information, and knowledge[edit] Relationship to other "INTs"[edit]
Future spacecraft could use dead stars to navigate The European Space Agency (ESA) wants to know if it’s possible to use dead stars as a navigational aid for traveling in deep space. To answer that question, ESA has contracted Britain’s National Physical Laboratory (NPL) and the University of Leicester to investigate whether pulsars can serve as navigational beacons in the far-flung reaches of the outer Solar System or interstellar space. With GPS, smartphones and online maps, navigation has become so simple that we hardly give it a thought anymore – unless a software glitch has the satnav telling us to drive into a lake. For probes heading into deep space, it’s another matter. Currently, spacecraft are guided by radio signals from ground stations on Earth or other spacecraft, but the farther out one goes, the less reliable radio signals become.
Astrium and EADS Innovation Works Partner with Dassault Systmes to Design the Future of Space Vehicles Dassault Systmes (Euronext Paris: #13065, DSY.PA), a world leader in 3D and Product Lifecycle Management (PLM) solutions, announced today a joint project with Astrium, Europes number one space company, and EADS Innovation Works, the corporate research and technology network of EADS, to develop solutions based on Dassault Systmes Version 6 platform that will enable to improve Astriums and EADS internal engineering methods, through the use of an innovative and revolutionary concept: the functional digital mockup (FDMU). The FDMU, unlike a digital mockup, which is associated more to the 3D geometry of a vehicle, will play an essential role during the exploration design phase. Based on Dassault Systmes RFLP (Requirements, Functional, Logical, and Physical) concept, it will add a whole new dimension to multi-disciplinary collaboration at various stages of development, using CATIA, ENOVIA and SIMULIA. The project is expected to produce its first conclusions by the end of 2011.
Military satellites market growth suffers from budgetary challenges back to News Friday 25 January 2013, Amsterdam In 2012 the global military satellite market valued US$11.8 billion and is expected to value US$17.3 billion by 2022, representing a CAGR of 3.9% during the forecast period. The demand for military satellites is anticipated to be driven by the need for enhanced communication capabilities and Intelligence, Surveillance and Reconnaissance (ISR) requirements for armed forces across the world.

Could you explain the Space Solar Power Systems project. Laser beam-type SSPS The Space Solar Power Systems project is a space-based solar power plant that generates energy by collecting sunlight in geostationary orbit.
The 1945 Proposal by Arthur C. Clarke for Geostationary Satellite Communications Sir Arthur C. Clarke's most famous prediction on the future is his proposal of geostationary satellite communications published in the Wireless World magazine in 1945. Not considered seriously at the time it became a reality within 20 years with the launching on 1965 April 6th of Intelsat I Early Bird the first commercial geostationary communication satellite. A satellite in an equatorial circular orbit at a distance of approximately 42,164 km from the center of the Earth, i.e., approximately 35,787 km (22,237 miles) above mean sea level has a period equal to the Earth's rotation on its axis (Sidereal Day=23h56m) and would remain geostationary over the same point on the Earth's equator.
