Spacecraft Operation - Post event analysis

The proton flux measured by SOHO/ERNE and observed GOES SXR flux
during the 13 December 2006 SEP event.
The service “Spacecraft Operation - Post event analysis” aims to provide the possibility to correlate a particular spacecraft effect experienced during the operation of a spacecraft with space environment data. To obtain a quantitative assessment of the space environment at a given time in the past, the ESA Space Weather Service Network provides an archive of the monitoring of phenomena that can lead to potentially hazardous and sudden effects on spacecraft (e.g. magnetic storms, substorms, high-speed streams, solar energetic particle events, Earth-directed CMEs, meteor streams, and debris clouds). The space environment data near the location of the spacecraft can then be compared to specific spacecraft conditions in terms of the observed effects or anomalies.
The service is intended for personnel such as spacecraft operators who want to understand the cause of observed effects or anomalies in spacecraft (e.g. SEE, ESD, errors in magnetorquing and sudden drag-induced orbit changes in LEO) in order to take the necessary precautions in case similar space weather conditions occur again, and and use this information for future spacecraft models or versions.
This service is implemented through a combination of products and tools which can be found through the following tabs along with expert support provided by the teams constituting the ESA Space Weather Service Network. Should you require further guidance in the use of this service, or have specific questions about any aspects of the service presented here, don’t hesitate to contact the Helpdesk.

Transient space weather phenomena (e.g. solar flares, coronal mass ejections, solar energetic particles, ...) can cause sudden and large changes in the space environment. Although spacecraft, equipment and components are designed to operate in this harsh and changing environment, space weather events can still cause anomalous behavior. In particular, an increase can occur in:
- rates of destructive and non-destructive single event effects;
- surface potentials;
- internal charging levels;
- dose and non-ionising energy loss degradation;
- magnetic torque deviations;
- drag causing orbit alteration;
- EM interference;
- comminucation distruptions.
From the Products tab, a range of products can be accessed that provide information on space weather events and the space environment conditions during a specific time in the past. Measurements and detection of solar flares and coronal mass ejections are available from the Solar Influences Data Analysis Center (SIDC) and the Kanzelhöhe Observatory (KSO). Solar wind conditions in the near-Earth environment can be obtained through the Product Browser of the Heliospheric Weather Expert Service Centre (HPARC). A catalogue of very high-energy solar particle events is provided by the University of Turku (UTU). An archive of energetic particle flux measurements (electrons, protons and helium) from the Energetic Particle Telescope (EPT) on board PROBA-V at LEO orbit can be accessed, as well as daily radiation situation reports comparing the measurements from several Standard Radiation Environment Monitors (SREM) in various key regions with reference particle rates are provided. The Solar Energetic Particle Environment Modelling (SEPEM) application server provides a reference event list for solar energetic protons, a reference data set for protons and helium, and tools to perform solar energetic particle statistical analyses on an extended set of cross-calibrated data. Besides forecasts for spacecraft effects and the radiation environment for the outer radiation belt and slot region, the SaRIF product also provides a post event reconstruction for the energetic electron spectra in those regions based on the BAS-RBM model. Archive of various geomagnetic indices are provided by the British Geological Survey (BGS), the Danish Technical University (DTU K, StormRisk), the Institute of Space Science Romania (FORIND), the German Research Centre for Geosciences (GFZ, GFZ Hpo), the German Research Centre for Geosciences (GFZ) and the SIDC.
From the Tools tab, a range of tools are accessible to support post event analyses for spacecraft operators. A large set of measurements can also be accessed through the Space Weather Data Browsing and Analysis (SWE Data) and AMDA web interfaces. The European Debris Impact Database (EDID) contains large database of events measured from debris and meteoroid impact detectors together with includes spacecraft housekeeping data. In order to understand the specific impact on a spacecraft, a tool such as the Space Environment Information System (SPENVIS) could be considered. This tool allows the execution of a set of space environment models based on a mission scenario. For this specific service, one could for instance look at differences between quiet and active space environment conditions.

The facility provides access to the ODI database containing a large and comprehensive set of data about that environment as measured in-situ by a number of space missions. The user can select a set of space environment data appropriate to the engineering problem under study. SEDAT also offers a set of software tools, which can operate on the data retrieved from the database. These tools allow the user to carry out a wide range of engineering analyses. SEDAT is using a GUI written in Java.
EDID (European Debris Impact Database) provides automated data processing and dissemination functions for measurements retrieved from European debris and meteoroids impact detectors. It covers impacts from the DEBIE-1, DEBIE-2 and GORID detectors. Users can access more than 3,000,000 debris and micro-meteoroid event records plus sensor and spacecraft housekeeping data via a user-friendly web interface. Filters can be defined for each available parameter and be used for regular data retrieval.
The AMDA system provides an archive of planetary, solar wind, Earth magnetosphere and ionosphere mission and ground based products. In addition it supports a range of standard models such as magnetic footprints, magnetic fields, solar wind propagation to planets and probes as well as access to external databases of observations and simulations. A key functionality of the system is its embedded plotting, data mining and cataloguing functionalities which are extremely useful in relation to posteriori analysis.
SWE Data is a web application that provides access to a wide range of Space Weather related data sources covering the areas of the spacecraft, ionospheric, and ground effects. SWE Data allows the user to access all data contained in the repository providing analysis and visualisation tools from these disparate sources.
SEPEM (Solar Energetic Particle Environment Modelling) is a WWW interface to solar energetic particle data and a range of modelling tools and functionalities intended to support space mission design. The system provides an implementation of several well known modelling methodologies, built on cleaned datasets. It also gives the user increased flexibility in his/her analysis and allows generation of mission integrated fluence statistics, peak flux statistics and other functionalities. It also integrates effects tools that calculate single event upset rates and radiation doses for a variety of scenarios.
SPENVIS (Space Environment Information System) is a web-based interface for assessing the space environment and its effects on spacecraft systems and crews. The system is used for mission analysis and planning. SPENVIS includes several empirical models of the space environment covering mainly cosmic rays, solar energetic particles, the natural radiation belts, magnetic fields, space plasmas and the upper atmosphere. A range of engineering models are also available to help assess the effects of the space environment on spacecraft such as surface and internal charging, energy deposition, solar cell damage and SEU rates. Usually these later models take their inputs from the empirical models present in SPENVIS. The system also includes extensive background information on the space environment, the environment models and the related standards.
