As a response to ESA call for mission concepts for its Cosmic Vision 2015–2025 plan, we propose a mission called Darwin. Its primary goal is the study of terrestrial extrasolar planets and the search for life on them. In this paper, we describe different characteristics of the instrument. 
Future Space Missions to Search for Terrestrial Planets
Abstract Since the first exoplanet was discovered more than 10 years ago, this field has developed rapidly. Currently we know of more than 200 external systems of stars and planets, apart from our
Impact of ηEarth on the Capabilities of Affordable Space Missions to Detect Biosignatures on Extrasolar Planets
We present an analytic model to estimate the capabilities of space missions dedicated to the search for biosignatures in the atmosphere of rocky planets located in the habitable zone of nearby stars.
Opening a new window to other worlds with spectropolarimetry
A high level of diversity has already been observed among the planets of our own Solar System. As such, one expects extrasolar planets to present a wide range of distinctive features, therefore the

Direct imaging of molten protoplanets in nearby young stellar associations
During their formation and early evolution, rocky planets undergo multiple global melting events due to accretionary collisions with other protoplanets. The detection and characterization of their
What makes a planet habitable?
This work reviews factors which are important for the evolution of habitable Earth-like planets such as the effects of the host star dependent radiation and particle fluxes on the evolution of
Exoplanet science with a space-based mid-infrared nulling interferometer
One of the long-term goals of exoplanet science is the (atmospheric) characterization of a large sample (>100) of terrestrial planets to assess their potential habitability and overall diversity.
Atmospheric characterization of terrestrial exoplanets in the mid-infrared: biosignatures, habitability, and diversity
Exoplanet science is one of the most thriving fields of modern astrophysics. A major goal is the atmospheric characterization of dozens of small, terrestrial exoplanets in order to search for


A Kepler Mission, A Search for Habitable Planets: Concept, Capabilities and Strengths
The detection of extrasolar terrestrial planets orbiting main-sequence stars is of great interest and importance. Current ground-based methods are only capable of detecting objects about the size or
Data processing in nulling interferometry: case of the Darwin mission
This paper first gives an introduction to the broad features of the Darwin mission of ESA and then describes in some detail the data processing that is necessary to detect planets and spectrally
Interferometric coronography for the DARWIN space mission { Laboratory demonstration experiment
The DARWIN mission aims at directly detecting exoplanets, particularly telluric ones, around nearby stars and at performing a spectral analysis of their potential atmosphere. The major diculty in
Target star catalogue for Darwin Nearby Stellar sample for a search for terrestrial planets
In order to evaluate and develop mission concepts for a search for Terrestrial Exoplanets, we have prepared a list of potential target systems. In this paper we present and discuss the criteria for
Could We Search for Primitive Life on Extrasolar Planets in the Near Future
Abstract We revisit the idea of R. Bracewell and R. Angelet al.,that exoplanets around nearby stars could be detected in the IR (6–17 μm) and their spectra analyzed, searching for CO2, H2O, O3, CH4,
Detecting nonsolar planets by spinning infrared interferometer
THE only known planets are the nine in our Solar System, so the origin of the Solar System and of stars in general would be clarified if other planetary systems could be discovered. Likewise,

Analysis is developed to show that it is systematic errors, resulting from fluctuations in the null depth, that drive the instrument performance, a second-order combination of amplitude and phase errors is the dominant contributor.
One of the biggest challenges associated with a nulling-interferometer-based approach to detecting extrasolar Earth-like planets comes from the extremely stringent requirements of path length,
