Space physics

Space physics, also known as space plasma physics, is the study of plasmas as they occur naturally in the universe. As such, it encompasses a far-ranging number of topics, such as heliophysics which includes the solar physics of the sun: the solar wind, planetary magnetospheres and ionospheres, auroras, cosmic rays, and synchrotron radiation. Space physics is a fundamental part of the study of space weather and has important implications not only to understanding the universe, but also to practical everyday life, including the operation of communications and weather satellites. Space physics is unique from other fields of astrophysics which study similar phenomenon, in that space physics utilizes in situ measurements from high altitude rockets and spacecraft.

History

Swedish Institute of Space Physics

The Swedish Institute of Space Physics (Swedish: Institutet för rymdfysik, IRF) is a Swedish government agency. The institute's primary task is to carry out basic research, education and associated observatory activities in space physics, space technology and atmospheric physics.

Foundation

The IRF was founded in 1957 and the first Kiruna-designed satellite experiment was launched in 1968. The institute has about one hundred employees and has its head office in Kiruna. Other offices are situated in Umeå, Uppsala and Lund.

IRF, originally the Kiruna Geophysical Observatory, began as a department within the Royal Swedish Academy of Sciences. It has been a public research institute since 1973, under the auspices of the Swedish Ministry of Education and Culture.

Satellite experiments

IRF participates in several international satellite projects. At present, data from satellite instruments are being analysed to help us better comprehend the plasma-physical processes in the solar wind and around comets and planets. For example, the Swedish Viking and Freja satellites, with equipment from IRF on board, have greatly increased our knowledge of the auroral processes in the Earth’s magnetosphere, as have the microsatellites Astrid 1 and 2, launched in 1995 and 1998. IRF's own nano-satellite Munin (at 6 kg (13 lb) the smallest-ever research satellite) was launched in 2000. An IRF-built instrument on board the Indian satellite Chandrayaan-1 (launched 2008) collected data from the moon and new techniques for making particle measurements in space were tested on the Swedish satellite mission Prisma (launched 2010). IRF has instruments on board the following on-going satellite projects:

Swedish Institute

The Swedish Institute (Swedish: Svenska Institutet, SI) is a Government agency in Sweden with the responsibility to spread information about Sweden outside the country. It exists to promote Swedish interests, and to organise exchanges with other countries in different areas of public life, in particular in the spheres of culture, education, and research.

The main office of the Swedish Institute is located in Gamla stan in central Stockholm. There is also a branch abroad; the Swedish Cultural Centre in Paris (French: Centre Culturel Suédois). The agency has approximately 90 members of staff and its board is appointed by the Government of Sweden.

In early 2007 the Swedish Institute stated it was planning to set up an "embassy", the "House of Sweden", in Second Life, an Internet-based virtual world. This virtual office is not intended to provide passports or visas, but serve as a point of information about Sweden.

Other Swedish embassies in foreign countries are under the direct authority and control of the Swedish Ministry of Foreign Affairs.

Star Wars

Star Wars is an American epic space opera franchise, centered on a film series created by George Lucas. It depicts the adventures of various characters "a long time ago in a galaxy far, far away".

The first film in the series, Star Wars (later subtitled Episode IV: A New Hope), was released on May 25, 1977 by 20th Century Fox and became a worldwide pop culture phenomenon. It was followed by the similarly successful sequels The Empire Strikes Back (1980) and Return of the Jedi (1983); these three films constitute the original Star Wars trilogy. A prequel trilogy was later released between 1999 and 2005, which received a more mixed reaction from critics and fans, compared to the original trilogy. All seven films were nominated for or won Academy Awards, and were commercial successes, with a combined box office revenue of $4.38 billion, making Star Wars the fourth highest-grossing film series. The series has spawned an extensive media franchise—the Star Wars expanded universe—including books, television series, computer and video games, and comic books, resulting in significant development of the series's fictional universe. Star Wars also holds a Guinness World Records title for the "Most successful film merchandising franchise." In 2012, the total value of the Star Wars franchise was estimated at USD $30.7 billion, including box-office receipts as well as profits from their video games and DVD sales.
