Retired space executive Jeffrey D. Grant and former astronaut and retired U.S. Air Force Col. Pamela A. Melroy were elected Sept. 12 and will assume trustee roles Dec. 11.

“Leaders of this caliber come to Aerospace at an absolutely vital moment for the entire space enterprise,” said Steve Isakowitz, Aerospace president and CEO. “These leaders provide Aerospace with the critical expertise needed to continue navigating this dynamic era for civil, commercial and national security space communities.”

Grant retired as vice president and general manager of the Space Systems Division at Northrop Grumman Corporation, where he led efforts to develop space solutions for civil, military, and restricted customers. Prior to joining the private sector, he served the Intelligence Community for 21 years, working at the U.S. Central Intelligence Agency (CIA) and the National Reconnaissance Office (NRO).

Melroy is currently a member of the National Space Council Users’ Advisory Group and the Australian Space Agency advisory group, and earlier served as a U.S. Air Force officer and a NASA space shuttle pilot and commander. She logged more than 924 hours (over 38 days) in space as a pilot on space shuttle missions STS-92 and STS-112, and as a commander for STS-120. She previously served as deputy program manager for Space Exploration Initiatives at Lockheed Martin, senior technical advisor and director of field operations for the Federal Aviation Administration’s (FAA) Office of Commercial Space Transportation, and deputy director of the Tactical Technology Office for the Defense Advanced Research Projects Agency (DARPA).
