Building on a Mission: The Project Management Building, Home to the Center’s Directors

JSC 60th Anniversary

Following NASA’s selection of Houston as the site of a new center to manage the nation’s new and expanding human spaceflight program, on Nov. 1, 1961, the agency announced the opening of the Manned Spacecraft Center (MSC), today known as NASA’s Johnson Space Center (JSC). The MSC’s original functions included a new mission control center, training facilities for astronauts, facilities for testing spacecraft for the extreme environment of spaceflight, offices, and laboratories, with the overall goal of landing a man on the Moon and returning him safely to the Earth before the end of the decade. Construction of the nine-story Project Management Building at the Clear Lake site began on Dec. 5, 1962, and concluded on March 15, 1964. During construction, engineers and managers worked in 14 separate leased facilities in southeast Houston. The center’s first director, Robert R. Gilruth, took up residence in the interim headquarters in the Farnsworth and Chambers Building on March 1, 1962. Following the Project Management Building’s completion, Gilruth relocated his office to the edifice’s top floor on March 6, 1964. The move of all program managers and institutional directors was completed by the end of June 1964.

Over the decades, MSC’s directors and other top program and directorate leaders continued to be located in the Project Management Building. Originally designated as Building 2, the building swapped numbers with the Public Affairs Building, originally known as Building 1, on June 30, 1974, and has been known as Building 1 ever since. In 1987, workers replaced the original set of lobby doors with a vestibule and two sets of automatic sliding doors to improve the lobby’s climate control. In addition to routine renovations and upgrades, workers carried out an asbestos abatement throughout the building in July 1988 and renovated the lobby in September 2011.

In front of the Project Management Building, workers Installed an 88-foot flagpole in February 1965 to fly the American flag. During welcome home ceremonies for the Gemini 3 crew on April 1, 1965, officials raised an American flag they carried into orbit during their mission. That flag, along with a Gemini Program banner, flew 24 hours a day during every Gemini mission. Both were retired and placed on display after Gemini XII, the final mission of the program. The practice continues today, with the space station flag flying continuously since November 2000, when human occupancy of the orbiting laboratory began. Three other flagpoles were added later, including a 77-foot Texas flag pole, a 77-foot NASA flag pole, and a 70-foot mission flag pole, the last added in September 2000. In addition to lowering flags to half-mast for national memorial events, the flags are flown at half-staff each year on Remembrance Day in tribute to the astronauts lost in the Apollo 1, Challenger, and Columbia accidents.

Center Directors

While the specific programs they managed have changed over the years, the primary function of JSC’s directors has been to lead the world’s premier human spaceflight facility and the civil service and contractor employees who conduct the work of the center on behalf of the agency. Their varied activities have included leading management meetings, greeting astronauts after their return from space, dedicating new facilities, meeting with local politicians, world leaders, and celebrities, and many others to maintain America’s leadership in human spaceflight. This article and the series that follows will provide information into the 13 unique individuals who have led the human spaceflight center over the past 60 years and continue to lead us into the future of human exploration. This article focuses on roughly the first 10 years of MSC, to the first Moon landing and a little beyond, and the man who led MSC through that first decade.

Gilruth began his lengthy public service career in January 1937 at the National Advisory Committee for Aeronautics Langley Memorial Aeronautical Laboratory in Hampton, Virginia. By 1952, he was the assistant director of the Langley laboratory. On Oct. 1, 1958, NASA opened for business, and five weeks later created the Space Task Group (STG) at Langley with Gilruth as its director, charged with putting an American in space. Following President John F. Kennedy’s May 1961 announcement of the Moon landing goal, the STG outgrew its facilities at Langley to handle the additional work. On Sept. 19, 1961, NASA announced that the STG would relocate to Houston, and on Nov. 1 become the Manned Spacecraft Center, with Gilruth as its first director.

Gilruth oversaw the building of the center on Clear Lake while completing the Mercury missions and preparing for the more complex Gemini and Apollo programs, with the center’s workers dispersed in the MSC’s temporary facilities. By June 1964, all MSC employees had relocated to the new center even as construction of additional buildings continued. In June 1965, the new Mission Control Center in Houston controlled its first flight, Gemini IV, and has controlled all American human space missions since.

Right: In October 1970, Gilruth, third from right, with the American and Soviet delegations at Star City, Russia, to negotiate a proposed common docking system, that led to the Apollo-Soyuz Test Project joint mission in July 1975.

Gilruth’s leadership guided the painful recovery following the January 1967 Apollo 1 fire. On July 20, 1969, Apollo 11 landed on the Moon, and four days later the astronauts splashed down safely, fulfilling President Kennedy’s goal. Gilruth’s next leadership challenge took place in April 1970, safely returning the Apollo 13 crew after an explosion crippled their spacecraft on the way to the Moon. Looking beyond the Moon landing missions, Gilruth embarked on negotiations with Soviet counterparts that ultimately led to the first docking between American and Soviet spacecraft in 1975.

Right: In December 1973, lifelong avid sailor Gilruth prepares to step aboard the Outrigger, the boat he designed and built.

In August 1971, Gilruth watched the Apollo 15 splashdown, his last as MSC director, not from Mission Control but from the deck of the prime recovery ship USS Okinawa, greeting the astronauts as they stepped off the helicopter. In January 1972, he accepted a position at NASA Headquarters in Washington, D.C., and turned MSC management over to his deputy director, Christopher C. Kraft. Gilruth retired from NASA in December 1973, the same month he christened his multihull 52-foot sailboat Outrigger, a craft he designed and built himself. He continued to participate in NASA related activities for many years following his retirement. Gilruth died in 2000 at age 86, leaving a lasting legacy in human spaceflight.

The story continues next time as MSC is renamed after President Lyndon B. Johnson and transitions from Apollo through Skylab to the space shuttle.
