Strategic Knowledge Gaps (SKGs)
Strategic Knowledge Gaps, or SKGs, represent gaps in knowledge or information required to reduce risk, increase effectiveness, and improve the design of robotic and human space exploration missions. NASA uses SKGs to help inform research and investment strategies, and prioritize technology development for human and robotic exploration.
NASA enlisted the expertise of three analysis groups — the Lunar Exploration Analysis Group (LEAG)
, the Mars Exploration Program Analysis Group (MEPAG)
, and the Small Bodies Assessment Group (SBAG)
— to develop and refine SKGs.
The lists of SKGs will remain living documents, being updated as needed based on ongoing efforts by the analysis/assessment groups requested by NASA.
