Bill Todd in the Shuttle Simulator.
|Born||William L. Todd|
|Education||Geology, University of Houston|
|Title||Program Manager for Exploration Analogs|
William L. "Bill" Todd is Program Manager for Exploration Analogs at NASA's Johnson Space Center (JSC) in Houston, Texas. He has also served as a NASA Undersea Research Team Project Lead and Spaceflight Training Simulation Supervisor at NASA JSC. In 2001, he commanded the first NASA Extreme Environment Mission Operations (NEEMO) mission, a joint NASA-NOAA program to study human survival in the Aquarius underwater laboratory in preparation for future space exploration.
Todd grew up watching the Apollo launches from his beachfront hometown of Cocoa Beach, Florida, where his father was also employed in the space program. It was there, at a young age, that he was immersed in and captivated by both sea and space environments. Todd graduated from the University of Houston with a degree in geology in 1982. He has worked in and visited numerous underwater habitats and submersibles, and is interested in the parallels between living and working in outer space and "inner space".
NASA career 
Todd works for United Space Alliance at the Johnson Space Center in Houston, Texas. As a Simulation Supervisor in Spaceflight Training, Todd is responsible for developing and executing multi-national simulations used for training astronauts and flight control teams. He has also worked as an Operations Lead at the Mission Control Center in Moscow, Russia.
In 2000, Todd developed the NASA Undersea Research Team "NEEMO" (NASA Extreme Environment Mission Operations). This program utilizes the Aquarius laboratory as a research facility for space missions such as long-term space habitation. Todd served as an aquanaut on the 2000 "NASA SEATEST" mission and as the commander of the October 2001 NASA NEEMO 1 mission. He subsequently managed the "topside" teams for NASA missions, and was the Mission Director for NEEMO 7, NEEMO 8 and NEEMO 14. As of 2011, Todd remains the project manager for NEEMO. In June 2012, Todd piloted a DeepWorker 2000 submersible as part of the NEEMO 16 mission.
Todd was involved in the training for many spaceflights, including the first two flights to build the International Space Station, crew training for the deployment mission of the Italian-made Tethered Satellite System and for the first flight to rendezvous with the Mir Space Station. Earlier in his career, Todd worked as a Space Shuttle systems astronaut instructor for many missions including STS-31, the flight which deployed the Hubble Space Telescope. Todd also led the international training activities for STS-97/ISS 4A, which flew in November 2000.
Todd's wife, Karen, and their two daughters, Kristen and Kari, reside in Seabrook, Texas. Todd is a Professional Association of Diving Instructors (PADI) Divemaster who has made over 1000 dives. He is also an instrument-rated pilot, seaplane pilot and Explorers Club Fellow. Todd is a member of the SeaSpace Symposium and of the advisory board for the International Association for Handicapped Divers. His hobbies are lawn work, boating, diving and skiing with his family. He also plays guitar in his rock band, The Rockit Scientists.
