ESA's Advanced Concepts Team (ACT) Requests Ideas for NEO-Related Studies

The Advanced Concepts Team (ACT) of the European Space Agency (ESA) has released their 2008 Ariadna Call for Proposals. This call solicits studies related to NEOs. There is a zip file containing multiple documents related to the call.

From the call...

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.

Although mitigation and deflection options and requirements will be the primary focus of the studies, proposals will be welcomed from all fields of NEO research (e.g. innovative methods for detection and characterisation, impact effects, dynamics and simulations) and other fields of scientific and technical research provided the importance and benefit of the study can be justified with reference to:

1. Acquiring the capacity to utilise a NEO close encounter for research and technological demonstrations, and/or

2. Ensuring that a successful mitigation or deflection mission of a potential Earth impacting object will soon be comfortably within our technological capabilities.

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.

Therefore, as part of the proposal, researchers are expected to provide a consistent roadmap within their field of expertise, including brief descriptions of the underlying logic, the key steps and approximate timeline over the next two decades specifically for dealing with Apophis-class objects (in terms of size but not necessarily in terms of orbital characteristics or expected physical properties).
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.
This roadmap should include:

1. An assessment of the likely status of asteroid knowledge and technology in 2029.
2. An assessment of the desired status of asteroid knowledge and technology by 2029.
3. Some recommendations/steps required in order to achieve the desired technological goals by 2029 in order to make full use of the Apophis encounter for the definition of a reliable mitigation option

The recommendations/steps may include:

a. What research is key to reach the necessary technological level by 2029?
b. Identification of possible demonstration opportunities of space mission technologies over the next 20 years?
c. Processes necessary to have systems ready and in place, in preparation for the mitigation of an asteroid impact?

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.
