The Clean Space team invites the space community to a webinar on reliability for life extension or disposal.

Join the ESA Clean Space Team live on Tuesday, 25 May 2021, at 15:00 CEST, to understand the use of reliability analysis to ensure the success and safety of space activities.

“You can’t eliminate risk but you can manage it intelligently”

Silvana Radu, RAMS Engineer at ESA, and Fabrice Cosson, head of ESA’s RAMS section, will share their knowledge about reliability with you. They will in particular focus on the methods used to assess the reliability of disposing of a spacecraft at the end of life and to decide whether it is possible to extend the life of a satellite or if it is better to turn it off.

As mentioned on several occasions in this blog, Requirements on Space Debris Mitigation for ESA projects impose :

  • Deorbiting the spacecraft either above or below its current orbit depending of its localisation,
  • Passivating all energy to avoid explosions,
  • Performing either a controlled or uncontrolled re-entry depending of the risk of casualties
  • ­ compliant with the reliability requirement of above 0.90 at disposal

The job of Silvana and Fabrice is to evaluate the reliability of designs and decisions taken to comply with these regulations, and thus help:

  • ensure mission success
  • engineers to reduce the risks through the design of the spacecraft, therefore before launch and,
  • operators to manage those risk when they have to decide whether to prolong the life of their satellite or to switch it off.

At the end of the webinar, you should be able to understand:

  • the use of  Reliability, Availability, Maintainability, Safety (RAMS) analysis in the scope of achieving mission success and safety
  • the difference between approaches for reliability computed for overall mission and reliability at disposal

Silvana and Fabrice will also present:

  • the need for improvement in approaches to the end of life actions for satellites
  • potential methods used for decision for life extension and/or deciding for disposal
  • the applicability and usefulness of these methods for various cases
