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, (typically Technology Readiness Level (TRL) 1 through 3). The Strategic Astrophysics Technology (SAT) program matures technologies that address the needs of a specific future mission, taking them from the feasibility demonstration to a lab demonstration of a design that meets specific performance requirements (TRL 4 through 6). The final maturation stages (TRL 7 through 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 through a vetted Technology Development Plan (TDP). Occasionally, a mission concept in pre-formulation is well-enough defined to have a vetted TDP. When budget constraints allow, the COR program will fund the development of those technologies through a specific funding allocation in the Supporting Research and Technology budget. An overview of the Strategic Astrophysics Technology program may be found here.

NASA's Space Technology Mission Directorate funds a wide range of technology development, from very early proof-of-concept to flight demonstrations, and including significant support for astrophysics.

Targeted Technology Areas

The Astrophysics Division at NASA Headquarters solicits proposals under the Strategic Astrophysics Technology/Technology Development for Cosmic Origins Program (SAT/TCOP), with the goal of preparing key technologies for implementation in space flight missions. Selection of proposals for funding, under the SAT/TCOP portion of the annual ROSES selection are based on the following factors: (1) overall scientific and technical merit of the proposal; (2) programmatic relevance of the proposed work; and (3) affordability of the proposed work.

Technology needs are prioritized annually by the COR program, after soliciting input from the community through the COPAG or by individual submission. (

Results are published annually in the Program Annual Technology Report (PATR). In the 2014 PATR, the highest priority technologies were:

  1. High-Reflectivity Optical Coatings for UV/Vis/NIR;
  2. High-QE, Large-Format UV detectors;
  3. Photon-Counting Large-Format UV Detectors;
  4. Affordable, Light-Weight Large Aperture Optics;
  5. Wavefront Sensing and Control at the Nanometer Level; and
  6. High Efficiency UV Multi-Object Spectrometers

Technologies evaluated and rankings are summarized on p39 and discussed in Chapter 4 of the 2014 PATR.

COR Technology Prioritization

Every year the COR program reviews the gaps between currently available technology, and what is needed to achieve our COR science goals.

We strongly encourage contributions from the community. Please send us your thoughts on what technologies need to be developed to make future COR missions possible. More information, and input forms, are available at Forms are preferred before June 16, 2014, but may be submitted until June 30, 2014.
