context_page_description: Paul Sean Hill was the Director of Mission Operations at the NASA Lyndon B. Johnson Space Center in Houston, Texas. He was formerly a Flight Director in the Mission Control Center for Space Shuttle and International Space Station missions under the call sign "Atlas".
context_section_description: After four years in the Air Force, Hill started work at Johnson Space Center in 1990 as a Space Shuttle and Space Station operations engineer. At that time planning was underway for Space Station Freedom, which evolved into the International Space Station. Hill worked as a Flight Control Engineer for Barrios Technology Incorporated from 1990 to 1991, for Rockwell Space Operations Company from 1991 to 1993, and for NASA Johnson Space Center from 1993 to 1996. Hill led development of International Space Station assembly operations and integrated systems procedures. He participated in every formal Space Station design review, three extensive spacecraft redesign activities and wrote many of the initial Space Station activation procedures. He served as Joint Operations Panel Chairman.
  Hill's responsibilities soon expanded, eventually leading to his appointment as a Space Shuttle and ISS Flight Director in 1996, a position in which he served until 2005. In this post he was responsible for the safe conduct of manned space flight missions. Hill led the flight control team in flight preparation and execution from Mission Control, and supported over twenty Shuttle and International Space Station missions as a Flight Director. Each NASA Flight Director chooses a call-sign to represent his or her team; Hill chose "Atlas" as the call-sign for his flight control team.
  Hill led an independent assessment of the Chandra Space Telescope’s flight readiness for NASA Headquarters. In September 2002, Hill served as an aquanaut on the joint NASA-NOAA NEEMO 4 expedition (NASA Extreme Environment Mission Operations), an exploration research mission held in Aquarius, the world's only undersea research laboratory, four miles off shore from Key Largo. Hill and his crewmates spent five days saturation diving from the Aquarius habitat as a space analogue for working and training under extreme environmental conditions. The mission was delayed due to Hurricane Isadore, forcing National Undersea Research Center managers to shorten it to an underwater duration of five days. Then, three days into their underwater mission, the crew members were told that Tropical Storm Lili was headed in their direction and to prepare for an early departure from Aquarius. Fortunately, Lili degenerated to the point where it was no longer a threat, so the crew was able to remain the full five days.
  Hill led the Columbia accident investigation team responsible for detecting and locating early debris during re-entry; obtaining and analyzing all data collected by government agency sensors during entry; and coordinating radar testing with the Air Force Research Laboratory. He also led the team that developed on-orbit inspection and repair techniques for the Space Shuttle and was the lead Flight Director for its return to flight on mission STS-114. Interviewed in July 2004, Hill said, "Flying the Shuttle is a really dangerous business. But that is not a bad thing. That doesn't mean we should stop flying in space. You can make some changes to make parts of this dangerous endeavor safer, but in the end it's still dangerous."
  Hill served as Deputy Manager of the EVA Office at Johnson Space Center from 2005 to 2006, as Manager of Shuttle Operations in the Mission Operations Directorate (MOD) from 2006 to 2007, and as Deputy Director of Mission Operations during 2007. In December 2007 he became Director of Mission Operations, in which position he is responsible for Mission Operations support for manned space flight. Interviewed in January 2011 about the downsizing of the Mission Operations Directorate as the Shuttle program ends, Hill said, "I could not be more proud to be part of this great MOD team and the people that comprise this national treasure... The risk of fully eliminating it keeps me awake at night, both for the technical capability and the human impact to these people who are carrying the load for the cause."
