ACT Investments
The ACT program uses the NASA Research Announcement (NRA) as its investment vehicle. Links to the full solicitations and awards are listed in the table and a brief summary of each solicitation follows below.

Overview of Investments

ACT Roses 2008 NRA
16 proposals were awarded funding with a total dollar value over a three-year period of approximately $16 million. These projects will support the development of instrument components and subsystems technologies for Earth Science missions/measurements recommended by National Research Council (NRC) Decadal Survey.

ACT NRA 2005
14 proposals, for a total dollar value over a three-year period of approximately $12 million, were awarded to research, develop, and demonstrate component and subsystem technologies that provide core component and subsystem technology developments that will enable new Earth and Sun science measurements, and visionary concepts.

ACT NRA 2002
14 proposals were awarded funding within three three classes of instrument component and subsystem technologies: 1) innovative components and subsystems that enable new measurement
implementations and science investigations, 2) components and subsystems that improve current implementations in order to reduce life cycle cost and development risk, and 3) development of selected technologies that advance the state-of-the-technology in the selected domain and that have the potential to impact a broad set of future missions which are relevant to NASA Earth science.

ACT NRA 1999
23 proposals were awarded funding under the first ACT solicitation. The solicitation sought a wide range of proposals for requirements analyses, laboratory development and demonstration, and breadboard and/or pre-engineering model construction for instrument component and subsystem technologies.
