NASA ROSES-17 Amendment 50: Release of D.15 System-Level Segmented Telescope Design

Status Report From: NASA HQ
Posted: Friday, December 1, 2017

ROSES-17 Amendment 50: This amendment releases program element D.15 System-Level Segmented Telescope Design.

NASA is soliciting industry proposals to carry out one-year end-to-end system-level engineering design and modeling studies and associated testbed demonstrations of large (10-meter class or larger) segmented-aperture telescopes, with integrated coronagraphs that will lead to the identification of priority technology investments and subsequent support to start developing and maturing these technologies.

Two types of segmented-aperture observatory concepts have been identified for consideration. For missions focusing on advancing astronomy at ultraviolet, visible, and near-infrared wavelengths (i.e., HabEx and LUVOIR), particularly for directly imaging and spectroscopically characterizing exo-Earth candidates, a key technology priority is to show a path to achieve the needed sub-nanometer wavefront stability. For missions focusing on UVOIR and Exoplanet Scicence, either on-axis or off-axis architectures may be considered. For missions focusing on advancing astronomy at mid- and far-infrared wavelengths (i.e., OST), a key technology priority is to dramatically reduce mirror manufacturing and verification costs to enable future missions to have larger and less-expensive telescope primary mirrors.

Proposals in response to this solicitation are limited to for-profit U.S. industrial organizations of any size, although partnerships with and/or subcontracts to any other types of organizations are permitted.

A preproposal conference will occur on January 5, 2018, 3-5 PM Eastern Time. USA toll free number 1-844-467-4685 with participant passcode = 981671. NOIs are not requested for this program element. Proposals are due February 1, 2018.

On or about December 1, 2017, this Amendment to the NASA Research Announcement "Research Opportunities in Space and Earth Sciences (ROSES) 2017" (NNH17ZDA001N) will be posted on the NASA research opportunity homepage at and will appear on the RSS feed at:
