Darwin ( Space IR Interferometry Mission )

Darwin is a proposal for a European infrared interferometer in space. Its first aim is to detect Earth-like planets around nearby stars, and then to search for a signature of life, ozone in an atmosphere. It could also be used as a general-purpose infrared observatory.
Darwin was proposed to the European Space Agency (ESA) for a Cornerstone Mission in its Horizon 2000 Plus plan. In October 1995, ESA decided to study such an infrared interferometer as an option for its Interferometer Cornerstone. The Darwin and Edison teams have combined to promote the selection by ESA of this option. The Darwin advocacy team members are also members of the International Working Group on Space Interferometry , a pressure group for this type of mission. Final selection on cost, science and technology grounds will be made around 2000, for a launch in the period 2009 - 2017.

The Face of Venus, enables browsers to interactively access a geographical database of these features. Craters or coronae can be selected by size, type, and name status to create user-generated maps of the selected features, as well as a text listing. A dynamic ISMAP is created with clickable areas where users can obtain more information about any feature viewed on the map, or directly from the text list. Users may also elect to examine the distribution of their selected features by using hierarchical cluster analysis to generate a dendrogram of any groupings.
