Following the destruction of "Space Shuttle Challenger" with the next Shuttle mission, civilian Payload Specialists were excluded from flying Shuttle missions until 1990. By that time, RCA had been purchased by General Electric, and RCA Astro-Electronics became part of GE. As a result, Cenker was the only RCA Astro-Electronics employee, and only employee in the history of the facility under all of its subsequent names, to ever fly in space. The facility operated as GE Astro Space until it was sold to Martin Marietta in 1993. Then
Criticism of the Space Shuttle program costs through amortization. Development costs were expected to be recouped through frequent access to space. These claims were made in an effort to obtain budgetary funding from the United States Congress. Beginning in 1981, the space shuttle began to be used for space travel. However, by the mid-1980s the concept of flying that many shuttle missions proved unrealistic and scheduled launch expectations were reduced 50%. Following the "Challenger" accident in 1986, missions were halted pending safety review. This hiatus became lengthy and ultimately lasted almost three years as arguments over funding and the safety of the program continued. Eventually the
