Ariadna Call for Ideas 2008
NEO Encounter 2029
Politecnico di Milano.
Type of activity: 4 months study
Near Earth Objects (NEOs) come closer to us than any other bodies in the solar system yet despite this, we still know relatively little about options to tackle the threat that they represent.
Research and Study Objectives
The main aim of this Call for Ideas is to attract proposals for new and innovative scientific and technical studies, which will act as the first steps towards increasing our knowledge and level of preparation for the initiation of a NEO hazard mitigation response. Several study proposals will be accepted and these will lead to parallel medium term (4 month) research studies carried out in collaboration with ESA.
This Call for Ideas intends to focus on working together with members of the academic community with the goal to first define a step-by-step approach of the underlying research needed to effectively tackle Apophis-class asteroid impacts, and then subsequently to perform the first research steps in the proposed approach. The close fly-by of Apophis will be considered as a representative reference scenario.
The scientific and technical content of the study proposal will be of great importance but in addition particular emphasis shall be put on the logical integration and credibility of the proposed study as a first research step in a roadmap of required events and steps.
The proposed milestones contained within the timeline are expected to represent credible solutions, possible to achieve with the right amount of research, funding and direction. A generic roadmap is not expected, as ESA will eventually assemble all of the individual, specific roadmaps into on overall map integrating many fields of expertise. Instead the timeline should be specifically tailored to the researchers' expertise and should demonstrate the suitability of the proposed research study to act as a first building block within the proposed roadmap.
The recommendations/steps may include:
All findings and predictions are to be based on sound scientific and technological knowledge and realistic predictions. Proposers are encouraged to underline their reasoning with references to published papers and research results. The proposed Call for Ideas research studies should be feasible and constitute an important first step towards reaching the goals, as defined in the proposers' roadmap, by 2029. The study can lead directly to progress in the proposers' area(s) of expertise or alternatively provide a valuable, valid contribution towards achieving targets in another field of NEO research and technology. Unpublished, innovative ideas and concepts are strongly encouraged and will be regarded positively.
