Understanding On-Orbit Degradation: Insights from a Workshop at the Solar Terrestrial Centre of Excellence

On May 3, 2012, experts in the field of space solar missions gathered at the Solar Terrestrial Centre of Excellence (STCE) in Brussels to discuss ways to reduce or correct expected degradation and increase their useful lifespan. The workshop was organized by STCE with contributions from a wide range of institutions and expertise. This article summarizes various lessons learned from these contributions and offers recommendations for future and ongoing space missions.

Observed Degradation in Space Missions

The workshop began with an overview of observed degradation in several space solar missions. It was noted that most spacecraft experience some degree of on-orbit degradation due to radiation damage, thermal cycling, contamination, mechanical stress, etc., which can lead to reduced performance over time. In order for future missions to be successful it is important that we understand how these factors affect our spacecrafts’ performance so that we can design them accordingly.

Lessons Learned From Contributions

The following are some key insights gained from the contributions made during the workshop:

• Radiation Damage: It was noted that radiation damage is one of the main causes of on-orbit degradation and can result in decreased power output as well as other issues such as increased noise levels or even complete system failure if not properly accounted for during mission design.

• Thermal Cycling: Thermal cycling is another factor that needs to be taken into consideration when designing a mission since it can cause components to expand or contract leading to structural fatigue over time.

• Contamination: Contamination caused by outgassing materials or particles entering through vents can also have an impact on mission performance if not addressed properly.

• Mechanical Stress: Mechanical stress resulting from vibrations caused by launch vehicles or orbital maneuvers can also lead to component failures if not adequately accounted for during mission design.

Recommendations For Future Missions

Based on these insights, it was recommended that future spacecraft designs should take into account all potential sources of on-orbit degradation including radiation damage, thermal cycling, contamination and mechanical stress. Additionally, it was suggested that more research should be conducted into understanding how different materials respond under extreme conditions such as those encountered in space so that better decisions can be made when selecting components for use in future missions. Finally, it was proposed that more rigorous testing protocols should be implemented before launch so as to ensure optimal performance once a spacecraft reaches its destination orbit.

Contributors To The Workshop

This workshop would not have been possible without the valuable contributions made by experts representing various institutions around Europe including but not limited too; European Space Agency (ESA), National Aeronautics & Space Administration (NASA), German Aerospace Center (DLR), French National Center for Scientific Research (CNRS) , Technical University Munich (TUM) , Institute Pierre Simon Laplace (IPSL). We thank each contributor who participated in this event providing invaluable insight into how we can improve our understanding of on-orbit degradation and ensure successful outcomes with future space missions.
