Whitepaper: For a Comprehensive Space-Based Dark Energy Mission
A space-based mission would provide an unparalleled opportunity to explore dark energy, the biggest puzzle in physical science today. Independent analyses have shown that a comprehensive program combining results from supernovae, weak lensing, and baryon acoustic oscillations will be much more effective than any subset of them. Because the stakes are so high and our knowledge of the phenomenon ...
متن کاملDestiny: A Candidate Architecture for the Joint Dark Energy Mission
Destiny is a simple, direct, low cost mission to determine the properties of dark energy by obtaining a cosmologically deep supernova (SN) type Ia Hubble diagram. Its science instrument is a 1.65m space telescope, featuring a grism-fed near-infrared (NIR) (0.85-1.7 m) survey camera/spectrometer with a 0.12 square degree field of view (FOV) covered by a mosaic of 16 2k 2k HgCdTe arrays. For maxi...
متن کاملMission Reliability Estimation for Repairable Robot Teams
Many of the most promising applications for mobile robots require very high reliability. The current generation of mobile robots is, for the most part, highly unreliable. The few mobile robots that currently demonstrate high reliability achieve this reliability at a high financial cost. In order for mobile robots to be more widely used, it will be necessary to find ways to provide high mission ...
متن کاملPlanning to Fail: Mission Design for Modular Repairable Robot Teams
This paper presents a method using stochastic simulation to evaluate the reliability of robot teams consisting of modular robots. For an example planetary exploration mission we use this method to compare the performance of a repairable robot team with spare modules versus nonrepairable robot teams. Our results show that for this mission a repairable robot team can provide a higher probability ...
متن کاملDark Matter and Dark Energy
I briefly review our current understanding of dark matter and dark energy. The first part of this paper focusses on issues pertaining to dark matter including observational evidence for its existence, current constraints and the ‘abundance of substructure’ and ‘cuspy core’ issues which arise in CDM. I also briefly describe MOND. The second part of this review focusses on dark energy. In this pa...
