2010). This technology would provide unprecedented sensitivity, field of view, and spectroscopy of exoplanetary systems, with many subsidiary applications such as solar physics and the study of faint structures around bright objects (such as jets, halos, and winds).

8.2.5 Wireless Spacecraft Technologies has been added to fill a gap in the roadmap. The use of wireless systems in spacecraft avionics and instrumentation will usher in a new and game-changing methodology in the way spacecraft and space missions will be designed and implemented. Wireless avionics could provide numerous improvements over hard-wired architectures, such as inherent cross-strapping, an architecture that is extensible and reliable; reduction in cable mass; and a significant reduction in the cost and time of system integration and test.2

Two technologies in the roadmaps (8.3.1 Particles: Charged and Neutral and 8.3.2 Fields and Waves) seem to have so much overlap that they have been combined to form one entry. The title of the new technology is 8.3.1 Particles, Fields, and Waves: Charged and Neutral Particles, Magnetic and Electric Fields.


The panel identified the following list of six top technical challenges that help provide an organizing framework for setting priorities. Two pertain to crosscutting technologies, and the other four relate to specific important scientific goals. They are listed below in priority order.

1. Rapid Time Scale Development: Enable the exploration of innovative scientific ideas on short time scales by investing in a range of technologies that have been taken to sufficiently high TRLs and that cover a broad class of applications so that they can be utilized on small (e.g., Explorer and Discovery-class) missions.


2Avionics (including wireless avionics) is a crosscutting gap that is not addressed in the draft roadmaps (see Tables 4-1 and 4-2)
