TECHNOLOGY INVESTMENT BUDGET Decadal Findings: Because the future of planetary science depends on a well-conceived, robust, stable technology investment program, the survey strongly recommended that a substantial program of planetary exploration technology development should be reconstituted and carefully protected against all incursions that would deplete its resources. They recommended that the program should be consistently funded at approximately 6 to 8 percent of the total NASA Planetary Science Division (PSD)

From page 82... ...
As part of their efforts, after the decadal survey the PSD initiated a technology road-mapping exercise incorporating inputs from various sources to identify technologies that enable innovative science in more extreme environments on smaller missions on a more frequent cadence. These technology requirements were then integrated into the 2015 NASA Technology Roadmap and the 2017 NASA Technology Investment Plan.

Finding: NASA has implemented cost-effective ways to bring new technology up to TRL 6 and above, includ ing taking proactive steps to educate PI teams on the available technology and providing incentives in the announcement of opportunity for the incorporation of the technology in their proposed missions. TECHNOLOGY DEVELOPMENT PROGRESS ASSESSMENT To cost-effectively meet the breadth of environmental and mission enabling systems challenges, the decadal survey committee emphasized the need for continued investment in advancing multi-mission core technologies that address the following needs:

Electric Propulsion and Advanced Solar Arrays Decadal Findings: Vision and Voyages emphasized the importance of NASA continuing to invest in capabilitydriven technology such as electric propulsion to increase propulsion systems efficiency especially for outer planet and primitive body missions. Vision and Voyages also recommended that NASA consider making equivalent systems investments in the advanced Ultraflex solar array technology that will provide higher power at greater efficiency.
|
From page 86... ...
Finding: NASA has fully embraced the Vision and Voyages recommendations concerning electric propulsion and advanced solar arrays, and is making significant technology development progress in both. Aerocapture Decadal Findings: Vision and Voyages recommended that NASA consider making equivalent systems investments in aerocapture to enable efficient orbit insertion around bodies with atmospheres.
|
From page 87... ...
Aerocapture system-level design and development, however, is destination-specific, and when there is a specific mission requirement, the investment will need to be increased. Communications and Data Bandwidth Decadal Findings: Vision and Voyages recommended that NASA invest in increasing communications, optical communications, and data link bandwidth, which would be of major benefit for planetary exploration.

From page 88... ...
To enable future missions to fully utilize the promise of increased data rate, a comprehensive ground support system will be required. Finding: NASA has fully embraced the Vision and Voyages recommendation and is making meaningful investment in advanced communications technology development and flight demonstration.
|
From page 89... ...
Extreme Environments Decadal Findings: Vision and Voyages recommended that, as part of a balanced portfolio, a significant percentage of the PSD's technology funding be set aside for expanding the environmental adaptability of existing engineering and science instrument capabilities. Assessment: SMD has funded two specific programs targeted at technologies for extreme environments: Concepts for Ocean Worlds Life Detection Technology (COLDTech)

As new vehicles become available and qualified, the LSP develops opportunities to add them to NASA launch vehicle services options. In addition to the commercial launch vehicles, NASA's new Space Launch System is under development and could be an attractive option for some applications, as it has the capability to reduce interplanetary cruise time for science missions to the outer planets by 3 to 5 years, and potentially increase payload size.
