In August 2018, the National Academies of Science, Engineering, and Medicine (NASEM) released a midterm review of the current Planetary Decadal Survey, “Vision and Voyages for Planetary Sciences in the Decade 2013-2022.” The midterm study assessed NASA’s progress in implementing the recommendations of the Survey, providing guidance to NASA for the remaining years and recommendations for how to prepare for the next Survey. The Associate Administrator for Science, Dr. Thomas Zurbuchen, has provided a letter to the NASEM describing NASA’s response to the 24 recommendations from the planetary midterm report. This letter is available to the planetary community.
