NASA/Goddard Space Flight Center (GSFC) intends to issue a Request for Proposal (RFP) for development of a conceptual telescope design to meet the requirements of the Joint Dark Energy Mission (JDEM). The JDEM is a space-based, medium aperture, wide field, optical telescope with visible and near-infrared (NIR) imaging and spectroscopy using HgCdTe detectors.

JDEM will survey the sky to accurately measure the magnitude and redshift of a large sample of Type Ia supernovae (SNe Ia), spectroscopic redshifts of a large sample of galaxies for Baryon Acoustic Oscillation (BAO) studies, and accurate shape parameters and photometric redshift measurements of a large sample of galaxies for Weak Lensing (WL) studies. The Telescope Assembly portion of the observatory is expected to be a Three Mirror Anastigmat (TMA) with multiple tertiary mirrors that will provide the optical train to the Government developed JDEM instrument. The JDEM telescope is expected to have a primary mirror size of 1.5 meters in diameter and operate at a temperature of less than 243 Kelvin. The JDEM observatory is expected to be launched aboard a NASA provided EELV to an orbit around the Sun-Earth second Lagrange point (L2) and operate for a minimum of 5 years. NASA contemplates evaluating and selecting multiple offers (approximately 2) based on the proposals as submitted and providing each of the study participants a not to exceed cost of $400K for a five month study. This study activity is intended to determine feasible telescope concepts based on the preliminary requirements. The study will assess the critical thermal, optical, mechanical and dynamic environments that drive the performance of the JDEM telescope, as well as the critical cost, schedule and technical performance drivers. NASA will provide preliminary mathematical models of the spacecraft and instrument for use by the study participants in the development of integrated models of their telescope conceptual designs. The models will provide preliminary information on spacecraft and instrument interfaces and forcing functions, including mechanical, thermal, optical and dynamic considerations. The study will also request results of trade studies performed in the course of the study, the results of integrated modeling performed for the proposed design concept, and a description of the telescope integration and test flow along with a recommended optical test flow at temperature. Cost and schedule estimates for the design, build and test of the JDEM telescope will also be generated. It is anticipated that the information relative to this concept study, including a draft Statement of Work, will be posted to the JDEM website at .

The Government does not intend to acquire a commercial item using FAR Part 12. See Note 26.

The NAICS Code and Size Standard are 541330 and 500, respectively.
