Weiler most recently was the associate administrator of NASA’s Science Mission Directorate at the space agency’s headquarters in Washington, D.C.
Weiler directed research and science programs including heliophysics, planetary science and astrophysics.
“Ed leaves an enduring legacy of pride and success that forever will remain a part of NASA’s science history,” NASA Administrator Charles Bolden said. “His leadership helped inspire the public with each new scientific discovery, and enabled NASA to move forward with new capabilities to continue to explore our solar system and beyond.”
Chuck Gay, the directorate’s deputy associate administrator, will act in Weiler’s place as associate administrator until a permanent replacement is announced.
