FREJA was a Swedish satellite developed by the Swedish Space Corporation on behalf of the Swedish National Space Board. It was piggyback launched on a Long March 2C launch vehicle from Jiuquan Satellite Launch Center in China on October 6, 1992. The satellite's total cost was 19 million U.S. dollars, excluding the costs of experiments.

BepiColombo is a joint mission of the European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA) to the planet Mercury. The mission comprises two satellites launched together: the Mercury Planetary Orbiter (MPO) and Mio. The mission will perform a comprehensive study of Mercury, including characterization of its magnetic field, magnetosphere, and both interior and surface structure. It was launched on an Ariane 5 rocket on 20 October 2018 at 01:45 UTC, with an arrival at Mercury planned for on 5 December 2025, after a flyby of Earth, two flybys of Venus, and six flybys of Mercury. The mission was approved in November 2009, after years in proposal and planning as part of the European Space Agency's Horizon 2000+ programme; it is the last mission of the programme to be launched.

The Swedish National Space Agency is a Government agency in Sweden operating under the Swedish Ministry of Education and Science. SNSA operates as a key component of the Swedish space programme, which is mostly carried out through international cooperation, and has included a sequence of satellite missions, both national ones and in cooperation with other nations. Furthermore, the agency distributes government grants to research and development, initiates research and development in space and remote sensing, and acts as the Swedish contact in international cooperative efforts.

<span class="mw-page-title-main">Plasmasphere</span> Region of Earths magnetosphere consisting of cool plasma

The plasmasphere, or inner magnetosphere, is a region of the Earth's magnetosphere consisting of low-energy (cool) plasma. It is located above the ionosphere. The outer boundary of the plasmasphere is known as the plasmapause, which is defined by an order of magnitude drop in plasma density. In 1963 American scientist Don Carpenter and Soviet astronomer Konstantin Gringauz proved the plasmasphere and plasmapause's existence from the analysis of very low frequency (VLF) whistler wave data. Traditionally, the plasmasphere has been regarded as a well behaved cold plasma with particle motion dominated entirely by the geomagnetic field and, hence, co-rotating with the Earth.

The Fanhui Shi Weixing series of satellites was China's first reconnaissance satellite program. The satellites were used for military reconnaissance and civilian imagery tasks and completed 23 missions between November 1974 and April 2016. There were four generations of the Fanhui Shi Weixing (FSW) satellites: FSW-0 from 1974 to 1987; FSW-1 from 1987 to 1993; FSW-2 from 1992 to 1996; and FSW-3 from 2003 to 2005. Two derivative models, the Shijian-8 (SJ-8) and Shijian-10 (SJ-10), were developed and launched as 'seed satellites' conducting bioastronautic experiments for the Chinese Ministry of Agriculture. All FSW-series satellites were launched into orbit using Long March rockets from the Jiuquan Satellite Launch Center (JSLC).
