.. The International Planetary Protection Handbook – Planetary Protection of Outer Solar System
PPOSS is a EU project
PPOSS: Planet Protection Outside of Solar System

The International Planetary Protection Handbook

Through background research, consultation and workshops, PPOSS will collect and assemble the information required to describe the rationales, the state-of-the-art and good practices to implement planetary protection requirements in the form of a handbook.

This handbook will include a historical perspective, up-to-date implementation measures used today, identification of problems and how to solve them, lessons learned, and aspects related to international cooperation (i.e. joint missions). The PPOSS handbook will be targeted to agencies, industry and scientific organisations involved in building spacecrafts and payloads with planetary protection constraints, in general and of Outer Solar System Bodies in particular.

The handbook will also serve as a reference to educate and train new stakeholders in the domain of planetary protection.

It is intended that the PPOSS handbook will represent an international baseline and a globally accepted document, to this end the international dimension and perspective is a core constraint in the production of the handbook. The PPOSS handbook is expected to be available early 2017.

In order to share and contribute to reaching a common ground for understanding the rationales, requirements and management of planetary protection issues at the international level, the PPOSS project will organise up to four seminars in interested countries (e.g., India, Japan, China, etc.) as well as in parallel with major international event. These seminars will be based on the outcomes of the project (in particular the planetary protection handbook) and will allow bringing experts in planetary protection to deliver lectures and technical sessions to an international audience.

While all the seminars will share the same common grounds and basis, PPOSS will endeavour to adapt the lectures to the specificities of the country and/or audience in which a given seminar is organised. This will allow maximising the impact of the knowledge transfer.
