Jeremy Graeber is the assistant launch director within the Exploration Ground Systems (EGS) Program at NASA’s John F. Kennedy Space Center in Florida. Graeber directly supports and assists Artemis Launch Director Charlie Blackwell-Thompson during launch countdown operations conducted from Firing Room 1 in the Launch Control Center, as well as with launch-related studies and trades for exploration missions.


Graeber previously served as the chief of the Test, Launch, and Recovery Operations Branch within EGS. This branch is responsible for planning and executing complex and hazardous test operations associated with integrated ground systems verification and validation, flight and ground systems integrated testing of the Space Launch System rocket and Orion spacecraft, and launch and recovery operations.

Graeber also worked as the Exploration Flight Test 1 (EFT-1) NASA Recovery director (NRD) for EGS. He was responsible for leading the EFT-1 recovery team that partnered with the U.S. Navy and successfully recovered the EFT-1 Orion crew module from the Pacific Ocean.

Graeber came to Kennedy in 1996 as a fuel cell/power reactant storage and distribution system engineer for United Space Alliance, the main contractor supporting the Space Shuttle Program. He was responsible for the test and checkout of the ground support equipment and flight vehicle fuel cell systems for all of the space shuttle vehicles. Graeber went on to be assigned as a lead fuel cell system engineer for the space shuttle Endeavour’s processing team.
