Lockheed Martin Space Systems "Columbia" launched on January 12, 1986, Bob Cenker became RCA Astro-Electronic's first astronaut. 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
British space programme Peter Longhurst (born in Staines, Middlesex) and RAF Squadron Leader Nigel Wood (born in York) were selected in February 1984 as payload specialists for the Skynet 4 Programme, intended for launch using the Space Shuttle. Boyle resigned from the programme in July 1984 due to Army commitments. Prior to the cancellation of the missions after the Challenger disaster, Wood was due to fly aboard Shuttle mission STS-61-H in 1986 (with Farrimond serving as his back-up) and Longhurst was due to fly aboard Shuttle mission STS-71-C in 1987 (with Holmes serving as back-up). All resigned in 1986, having not flown. Army
