DESTINY: The Dark Energy Space Telescope

摘要

We have proposed the development of a low-cost space telescope, Destiny, as a concept for the NASA/DOE Joint Dark Energy Mission. Destiny is a 1.65m space telescope, featuring a near-infrared (0.85-1.7m) survey camera/spectrometer with a large flat-field Field Of View (FOV). Destiny will probe the properties of dark energy by obtaining a Hubble diagram based on Type la supernovae (SN) and a large-scale mass power spectrum derived from weak lensing distortions of field galaxies as a function of redshift.
