NASA’s Planetary Science Division (PSD) is planning to host a community workshop at NASA headquarters in Washington, DC, on February 27–March 1, 2017. This workshop is meant to provide PSD with a very long-range vision of what planetary science may look like in the future. The workshop is to gather the leading experts in solar system planetary science and related disciplines, together with experts in space technologies, to identify potential science goals and enabling technologies that can be implemented by the end of the 2040s and would support the next phase of solar system exploration.
