“…A second set of high energy particle observations was obtained at Mars by the MARIE (Mars Radiation Environment Experiment) aboard NASA's Mars Odyssey spacecraft (Zeitlin et al, 2004). MARIE measured ions with energies in the range (∼20-200 MeV) while in circular orbit about the planet at a height of ∼400 km (Section 6.2).…”

Energetic particle data recorded by the SLED instrument aboard Phobos-2 while in circular orbit about Mars (6-26 March, 1989) showed the presence of magnetic shadowing. A 3-D, self consistent, hybrid model (HYBMars) supplemented by test particle simulations was developed to study the response of the Martian plasma environment to solar disturbances and to reproduce, in particular, the magnetic shadowing effect. The pertaining magnetic and electric fields as well as the properties of high energy ions present at Mars under conditions of extreme solar disturbances, can be derived from HYB-Mars. This model predicted a plasma phenomenon at the planet, named here 'solar wind-flow shadowing', which was earlier identified in the measurements of the ASPERA (plasma) experiment aboard Phobos-2. HYB also predicted magnetic shadowing which is qualitatively similar to that recorded by SLED. The simulations suggest that the configuration of a magnetic shadow depends on the pertaining solar wind density and velocity, and on the magnitude and direction of the interplanetary magnetic field. It is currently planned to input to the HYB model plasma and magnetic field data measured contemporaneously with the particle measurements aboard Phobos-2 so as to more realistically match the simulated results with the in situ observations.

“…Reports dealing with the potential hazards to astronauts (e.g., Zeitlin et al 2004) point out the need to monitor solar activity from many viewpoints to ensure adequate warnings of potential large SEP fluxes. LRO (Lunar Reconnaissance Orbiter), the first vision for Space Exploration mission launching in 2008, carries an energetic particle telescope that will measure the SEP events STEREO IMPACT will detect from other perspectives.…”

STEREO IMPACT Investigation Goals, Measurements, and Data Products Overview

The IMPACT (In situ Measurements of Particles And CME Transients) investigation on the STEREO mission was designed and developed to provide multipoint solar wind and suprathermal electron, interplanetary magnetic field, and solar energetic particle information required to unravel the nature of coronal mass ejections and their heliospheric consequences. IMPACT consists of seven individual sensors which are packaged into a boom suite, and a SEP suite. This review summarizes the science objectives of IMPACT, the instruments that comprise the IMPACT investigation, the accommodation of IMPACT on the STEREO twin spacecraft, and the overall data products that will flow from the IMPACT measurements. Accompanying papers in this volume of Space Science Reviews highlight the individual sensor technical details and capabilities, STEREO project plans for the use of IMPACT data, and modeling activities for IMPACT (and other STEREO) data interpretation.

“…SEPs also affect Earth's upper atmosphere chemistry, producing NO that leads to ozone depletions at high latitudes (Jackman et al 2005a, b;López-Puertas et al 2005;Rohen et al 2005). The effect of SEP events has been also observed at Mars (Zeitlin et al 2004), but their description at other bodies than the Earth still mainly relies on numerical simulations (Sheel et al 2012). …”

Space weather has become a mature discipline for the Earth space environment. With increasing efforts in space exploration, it is becoming more and more necessary to understand the space environments of bodies other than Earth. This is the background for an emerging aspect of the space weather discipline: planetary space weather. In this article, we explore what characterizes planetary space weather, using some examples throughout the solar system. We consider energy sources and timescales, the characteristics of solar system objects and interaction processes. We
