Future Physics of the Cosmos (PCOS) missions, as is the case for all astrophysics missions, will be enabled or greatly enhanced by continuous development and improvement of technologies beyond our current state of the art. NASA's Astrophysics Division funds the development of technology at all levels of maturity. The Astrophysics Research and Analysis (APRA) program funds technology development in the earliest phases, from basic research through the first feasibility demonstrations. This is typically in the Technology Readiness Level (TRL) range of 1–3.
The Strategic Astrophysics Technology (SAT) program matures technologies that address the needs of a specific future mission, taking them from proof of concept through validation in relevant environment demonstration (TRL 3–6). For more details on the SAT program, see the recent Perez et al. paper, "Technology maturation process: The NASA strategic astrophysics technology (SAT) program." The final maturation stages (TRL 7–9) focus on proving the technology's flight-worthiness for a mission-specific application. Thus, these stages are addressed by incorporating the technology into a flight project's implementation plan. Flight-testing may be done on a suborbital balloon or sounding rocket flight, funded through the above-mentioned APRA program.
NASA's Space Technology Mission Directorate funds a wide range of technology development, from basic principles to flight demonstrations, including significant support for astrophysics.
The Astrophysics Division solicits Technology Development for the Physics of the Cosmos Program (TPCOS) under the SAT, seeking to prepare strategic technologies for implementation in space flight missions. Selection of proposals for funding under the SAT/TPCOS portion of the annual ROSES selection is based on (1) overall scientific and technical merit of the proposal, (2) programmatic relevance of the proposed work, and (3) affordability of the proposed work. The ROSES SAT 2013 selection abstracts show the technologies most recently funded.
During FY13, per direction from NASA HQ, the PCOS program office developed two technology roadmaps for future X-ray astronomy and gravitational wave observatories:
Each year, the PCOS Program reviews and prioritizes gaps between currently available technology and what is needed to achieve our science goals. Our annual prioritization process begins with your important input regarding capabilities you believe are needed to enable or enhance future PCOS missions.
The PCOS Program Analysis Group (PhysPAG) is the main conduit for collecting technology gaps identified by the community. However, we also welcome direct contributions from the community, so please send us your thoughts on what strategic technologies we should develop to enable future PCOS missions using our downloadable technology gap submission form.
We will be working with the PhysPAG to consolidate technology gap submissions we receive by this year's cutoff date into a comprehensive list of unique and compelling entries. While we welcome gap submissions anytime, only those we receive by June 1, 2015 will be evaluated and prioritized by our Technology Management Board (TMB) in July. Later submissions will be evaluated in 2016.
The TMB uses a set of criteria that reflect our goals, as described in our Program Annual Technology Report (PATR), a key product of the Program's technology development process. The results of this year's TMB prioritization will be published in the 2015 PATR, to be released in October. When the Astrophysics Division drafts future calls for technology development, and makes investment decisions, they refer to the priority recommendations listed in the PATR.
The technology gaps evaluated in 2014 are described on pages 17-30 of the 2014 PATR, and rankings are summarized on page 33. The highest-priority technologies this year were:
We invite you to read the PATR to learn more about our technology management process and activities, the technology capabilities gaps submitted by the community, the priorities we assigned these for investment consideration during the upcoming year, and the status and plans of our current technology development investments.

Your inputs and suggestions are important to us! Whether you develop cutting-edge technology or use that technology to expand our understanding of the universe, we encourage you to read the PATR and tell us what you think. This is your opportunity to take an active role in shaping the future of PCOS science. Please feel free to comment on the technology gaps prioritization process itself as well.
