Wide Field Imager in Space for Dark Energy and Planets

TL;DR

A space-based wide-field imager could significantly advance dark energy and exoplanet research, but integrating it into larger missions is impractical and fiscally risky, requiring careful strategic planning.

Contribution

The paper argues for a focused approach to space-based wide-field imaging, cautioning against large, costly missions that combine dark energy and exoplanet studies.

Findings

Wide-field imagers can advance dark energy and exoplanet science.

Large, complex missions may hinder scientific progress and fiscal responsibility.

Strategic mission planning is essential for effective scientific outcomes.

Abstract

A wide-field imager in space could make remarkable progress in two very different frontiers of astronomy: dark energy and extra-solar planets. Embedding such an imager on a much larger and more complicated DE mission would be a poor science-approach under any circumstances and is a prescription for disaster in the present fiscal climate. The 2010 Decadal Committee must not lead the lemming stampede that is driving toward a DE mega-mission, but should stand clearly in its path.
