Objectives of the CSES Satellite (Chinese Seismo-Electromagnetic Satellite)
The objectives of the Project CSES are described in the following aspects: scientific, engineering and application ones.
The objectives in the scientific aspect of the project are to study the ionospheric perturbations possibly associated with earthquakes, specially with destructive ones, and to explore new approaches for short-term and imminent prediction, as well as to find a new orientation for the theoretical studies on the mechanism of the earthquake preparation processes.
The objective in the engineering aspect of the project are to check the reliability and effectiveness of the proposed electromagnetic satellite monitoring system by utilizing a set of new techniques and equipments, in order to obtain world-wide data of space environment of the electromagnetic field, plasma and energetic particles.
The objectives for the aspect of application of the project are to extract the electromagnetic information possibly associated with the earthquakes of M≥6 within Chinese territory and its neighboring area (1000 km) and that of M≥7 in the global scale; to analyze the features of seismo-ionospheric perturbations, in order to test the possibility for short-term earthquake forecasting experimentally in terms of satellite observation; to provide the data sharing service for international cooperation and scientific community.
Mission contents of CSES
1. Measurement of signals from electromagnetic emission and its perturbations in inonosphere;
2. Measurement of the disturbance of plasma in ionosphere, such as: contents, density and temperature of the ions, density and temperature of the electron, total electron contents, etc.
3. Measurement of energetic particles precipitations
According to the mission, the scientific payload of the satellite includes: Search coil Magnetometer, Fluxgate Magnetometer, Electric field detector, GPS occultation Receiver, Plasma analyzer, Langmiur probe and Energetic particle detector.
In 2011, the SPACEWEATHER experiment received the approval by INFN for the development and the
realization by Italian groups of Roma 2 Tor Vergata, Perugia and LNF of a series of detectors for CSES (mini-magnetic spectrometer, electric field detector, magnetic field detector, low frequency e.m. wave detector), to study the fast variations of the fluxes of protons and electrons trapped in the radiation belts due to perturbations caused by seismic events.
SIRAD
The task of the SIRAD experiment (approved by ESA and ASI in Phase A within the Program FEBO) is
to develop a detector to be placed on the external part of the ISS. The detector will be used to
monitor cosmic rays and radiation environment in Low Earth Orbit. Long term (Solar modulation)
and short term (coronal mass ejections, orbit dependence) eff ects on the particle
flux will be monitored as well as the dose absorbed by the astronauts. In addition, data will be compared with measurements taken inside the ISS with ALTEA, ALTEINO and LAZIO/SIRAD detectors
to validate radiation transport and dose estimation codes. At the same time, the investigation,
with a more sophisticated instrument, of the "Light Flashes" phenomenon, will be conducted
to improve and re fine the results obtained with the previous SIEYE experiments. |
