In 2003, NASA all started an R&D attempt to boost nuclear energy and propulsion structures for sun method exploration. This task, renamed undertaking Prometheus in 2004, was once initiated due to the inherent boundaries in photovoltaic and chemical propulsion platforms in achieving many sun approach goals. to assist confirm acceptable missions for a nuclear energy and propulsion potential, NASA requested the NRC for an self sustaining review of probably hugely meritorious missions that could be enabled if house nuclear platforms grew to become operational. This document presents a chain of house technological know-how targets and missions which may be so enabled within the interval past 2015 within the parts of astronomy and astrophysics, sun process exploration, and sunlight and house physics. it's in response to yet doesn't reprioritize the findings of past NRC decadal surveys in these 3 components.

Elements of this program consist of large (>$400 million), medium (between $250 million and $400 million), and small (<$250 million) space- and groundbased projects backed up by theoretical, computational, and modeling activities and related research and dataanalysis programs. The SSP decadal survey identified only one large (>$400 million) program, the Solar Probe, a spacecraft intended to study the heating and acceleration of the solar wind. 3 AU to as close as 3 solar radii above the Sun’s surface).
Nuclear systems will likewise need to be validated for reliable operation at full power and for mission lifetime. , missions using nuclear-electric propulsion (NEP) to the outer solar system—require continuous operation without maintenance or repair for periods as long as 10 to 20 years. No high-power-density reactor has, however, ever been operated on Earth, without maintenance shutdowns, for any period longer than one order of magnitude or more below such a duration. CANDIDATE SOURCES OF ELECTRICAL POWER AND PROPULSION Nuclear-Electric Propulsion Currently, NASA’s Project Prometheus is pursuing the development of NEP systems.
The three decadal surveys represent the community consensus that emerged from extensive consultations with, and deliberations among, hundreds of individuals in the respective communities. The committee believes strongly that this consensus is compelling. Thus, it is an exercise in due diligence to require that the science objectives and high-priority missions within those surveys retain their priority unless new scientific priorities have emerged with community-wide consensus in the time since the decadal surveys were completed.
