TL;DR: The Nearby Earth Astrometric Telescope (NEAT) as discussed by the authors is designed to carry out space-borne extremely high-precision measurements at the 0.05 mu as (1 sigma) accuracy level, sufficient to detect dynamical effects due to orbiting planets of mass even lower than Earth's around the nearest stars.

TL;DR: The DUAL payload as discussed by the authors consists of an All-Sky Compton Imager (ASCI) and two optical modules, the Laue-Lens Optic (LLO) and the Coded-Mask Optic(CMO).

TL;DR: The European Venus Explorer (EVE) mission described in this paper was proposed in December 2010 to ESA as an 'M-class' mission under the Cosmic Vision programme as discussed by the authors, consisting of a single balloon platform floating in the middle of the main convective cloud layer of Venus at an altitude of 55 km, where temperatures and pressures are benign (∼25°C and ∼0.5 bar).

TL;DR: In 2009, the Centre National d'Etudes Spatiales (CNES) carried out an assessment study on a "Fresnel telescope" concept based on a two-spacecraft formation flying configuration as discussed by the authors.

TL;DR: MAX as discussed by the authors is a space-borne crystal diffraction telescope, featuring a broad-band Laue lens optimized for the observation of compact sources in two wide energy bands of high astrophysical relevance.
