STORM - Solar system plasma Turbulence:  Observations, inteRmittency and Multifractals

Data Bases

STORM targets data from solar system missions equipped with plasma and electromagnetic field instruments, including magnetometers, electron and ion spectrometers, wave analysers. The STORM "core" missions are the European missions Ulysses - the solar wind monitor, Cluster - a state of the art multi-point mission in the Earth's magnetosphere and Venus Express - the mission to Venus. The analysis tools developed and tested in STORM will be applied on data from other European and American missions, like Giotto, Cassini, THEMIS.


Ulysses spacecraft

The solar wind mission

Ulysses is the first satellite that provided views of the Sun's poles. The scientific instruments on board Ulysses detect and measure solar wind ions and electrons, magnetic fields, energetic particles, cosmic rays, natural radio and plasma waves, cosmic dust, interstellar neutral gas, solar X-rays and cosmic gamma-ray bursts. The spacecraft was laubched in October 1990 and collected data until June 2009. Its orbit ranged from Jupiter to ~1.4 AU from the Sun and back out again, with a period of 6.2 years.

The European mission to Venus

Venus Express is the twin sister of the Mars Express satellite and is the European mission to Venus, the second planet from the Sun that lies, on average, 108 million km from the Sun, about 30% closer than the Earth. Venus is often referred to as our sister planet because of similarities in size, mass, density and volume. It is believed that both planets share a common origin forming at the same time out of a condensing nebulosity around 4.5 billion years ago.

The terrestrial mission


Cluster is a unique multi-spacecraft mission launched in 2000 by the European Space Agency. Four identical satellites fly in a tethraedral formation on an eliptic orbit between 19000 and 119000 kilometer altitude. The main objective of Cluster is to investigate the Earth’s magnetosphere and its interaction with the solar wind (Escoubet et al., 2001). The spacecraft continue to collect data since 2000, the mission has been extended until 2016.
