The service “Spacecraft Design - Post event analysis” aims to provide means to correlate particular (spacecraft) anomaly events with space environment data (e.g. space particle radiation, plasma, microparticles, and electromagnetic radiation). By means of space environment data and tools (e.g., superposed epoch analysis, data mining), the ESA Space Weather Service Network allows the user to analyse and correlate the space environment at a given time and/or location with effects and anomaly events on specific spacecraft, equipment or components. The service, intended for personnel involved in spacecraft design, operates within the limitations brought by data confidentiality of the spacecraft information. Information on the vulnerability of components, equipment or spacecraft based on the performed analyses could be used as input 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.
A set of models and in-orbit sensor datasets are provided with the help of tools and products such as:
- the Space Environment Information System (SPENVIS) coupling several empirical and engineering models of the space environment and its effects on spacecraft or components based on a mission planning;
- the Space Environment Data System (SEDAT) allows engineering analyses to be carried out on datasets related to the spacecraft charged particle environments;
- the Solar Energetic Particle Environment Modelling application (SEPEM) allowing solar energetic particle statistical analyses on an extended set of cross-calibrated data;
- the European Debris Impact Database (EDID) provides data processing and dissemination functions for measurements from European debris and meteoroid impact detectors;
- the Space Research Laboratory Solar Energetic Particles (UTU-SEP) products provide access to a high energy SEP event list as well as the calculation of the expected high energy proton fluence and worst-case proton flux for a specific mission length due to SEPs;
- measurements and derived data products from the Energetic Particle Telescope (EPT) on PROBA-V;
- measurements and derived data products from the Standard Radiation Environment Monitors (SREM) on Proba-1, Integral, Rosetta, Herschel and Planck;
- the electron population model from Mullard Space Science Laboratory (MSSL) for LEO, MEO and GEO as function of solar wind speed and Kp index;
- the SWIFF Plasmasphere Model (SPM) dynamical simulation provides the number density and temperatures of the electrons as a function of time;
- the Satellite Risk Indicators Forecast (SaRIF) provides colour-coded risk indicators showing the risk from internal charging and total ionising dose for the outer radiation belt and slot region, as well as a recontruction of these environments;
- the Space Weather Data Browsing and Analysis (SWE Data) provides access to space weather environment data.

Spacecraft need to be able to withstand the effects that the multitude range of phenomena (e.g. solar flares, coronal mass ejections, solar energetic particle events) in the dynamic space environment may have on technology. The goal of spacecraft radiation shielding is to protect the crew and hardware (exterior and interior) from the radiation environment encountered in space. When designing and building a spacecraft both short- and long-term cumulative effects must be considered. Identifying the cause of an unexplained technical anomaly event is important, as this information can help improve the designing of future efficient shielding.
A good starting point for a post-event analysis is a tool such as SEDAT (Space Environment DATa system). SEDAT allows a wide range of engineering analyses to be carried out using a comprehensive set of in-situ space environment datasets. The flexibility of the tool authorises the tailoring of the data processing to the problem under study and the incorporation of new datasets.
Specific particle radiation data provided through the network are based on the measurements from the Energetic Particle Telescope (EPT) on PROBA-V, and from the Standard Radiation Environment Monitors (SREM) on Proba-1, Integral, Rosetta, Herschel and Planck. Time series of the energetic electron, proton and helium fluxes as measured by EPT are available, as well as weekly geographical flux maps for each particle species and energy channel. Weekly energy spectra are provided for auroral electrons as well as proton and helium in the South Atlantic Anomaly. Daily radiation situation reports based on the SREM data in several key regions along the orbit of the various spacecraft are provided. Daily measurements of particle radiation levels and spectra are compared with reference models for the proton and electron belts, the slot region, and interplanetary space. 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.
In order to study the specific impact on a spacecraft in more depth, 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 (mission duration, typical spacecraft trajectories and spacecraft attitude) and to evaluate impacts and risks by propagating the results into engineering models. The tool includes graphical visualisation and an extended help with background information and references to the European standards. For a more comprehensive analysis of the space environment effects, the SPENVIS output could be exported to more specific applications, such as GRAS (Geant4 Radiation Analysis for Space) or SPIS (Spacecraft Plasma Interaction Software), that are taking into account the detailed geometry of the spacecraft.
When interested in the impact of microparticles, the European Debris Impact Database (EDID) could be accessed which has a large database of events measured from debris and meteoroid impact detectors together with includes spacecraft housekeeping data.
The user who is interested in an overview of the typical programmatic concerns related to the space environment is invited to visit the service page for "Spacecraft Design - Environment specification: data archive".

Long-term Solar Cycle Prediction
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.
SEDAT (Space Environment Data System) is a tool for the engineering analysis of spacecraft charged particle environments. 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.
