“…There are two other papers in this conference [5,6] that discuss in some detail the lessons learned in the process of building and operating this Great Observatory. The entire process has taken thirty-eight years (and counting) from the initial unsolicited proposal of Giacconi and Tananbaum in 1976 to the upcoming celebration of the 15-th anniversary of the launch in July 2014.…”

NASA's Chandra X-Ray Observatory, designed for three years of operation with a goal of five years, is now entering its 15-th year of operation. Thanks to its superb angular resolution, the Observatory continues to yield new and exciting results, many of which were totally unanticipated prior to launch. We discuss the current technical status, review some recent scientific highlights, indicate a few future directions, and present what we are the most important lessons learned from our experience of building and operating this great observatory.

“…The spacecraft and mission design leverage existing heritage and benefit from simplicity of operation. Chandra, for example, has produced many Lessons Learned 12 that Lynx will incorporate. The spacecraft design and mission operations borrow heavily from the Chandra Observatory, the only X-ray observatory to date to achieve sub-arcsecond angular resolution 13 .…”

Lynx, one of four strategic mission concepts under study for the 2020 Astrophysics Decadal Survey, will provide leaps in capability over previous and planned X-ray missions, and will provide synergistic observations in the 2030s to a multitude of space-and ground-based observatories across all wavelengths. Lynx will have orders of magnitude improvement in sensitivity, on-axis sub-arcsecond imaging with arcsecond angular resolution over a large field of view, and high-resolution spectroscopy for point-like and extended sources. The Lynx architecture enables a broad range of unique and compelling science, to be carried out mainly through a General Observer Program. This Program is envisioned to include detecting the very first supermassive black holes, revealing the high-energy drivers of galaxy and structure formation, characterizing the mechanisms that govern stellar activity -including effects on planet habitability, and exploring the highest redshift galaxy clusters. An overview and status of the Lynx concept are summarized.

“…We anticipate benefit from the early development of high-fidelity simulations as a tool to illuminate the tall poles in the error budget, guide the choices toward performance optimization, and enable strategic comparisons by providing an integrated end-to-end measure of the entire process. 25,26 Our Chandra experience has shown that multiple independent performance predictions are needed to inject sufficient discourse into the development process to have confidence that test results will satisfy requirements, 27,28,29 so we approach the problem by starting to develop a flexible set of tools, which are specific to the mounting and alignment problem and independent of other likely methods.…”

Active figure control effects on mounting strategy for x-ray optics

et al. 2014

View full text Add to dashboard Cite

As part of ongoing development efforts at MSFC, we have begun to investigate mounting strategies for highly nested xray optics in both full-shell and segmented configurations. The analytical infrastructure for this effort also lends itself to investigation of active strategies. We expect that a consequence of active figure control on relatively thin substrates is that errors are propagated to the edges, where they might affect the effective precision of the mounting points. Based upon modeling, we describe parametrically, the conditions under which active mounts are preferred over fixed ones, and the effect of active figure corrections on the required number, locations, and kinematic characteristics of mounting points.
