Robert J. Cenker

Robert Joseph Cenker (born November 5, 1948) is an American aerospace and electrical engineer, aerospace systems consultant, and former astronaut. Cenker worked for 18 years at RCA Astro-Electronics, and its successor company GE Astro Space, on a variety of spacecraft projects. He spent most of his career working on commercial communications satellites, including the Satcom, Spacenet and GStar programs.

In January 1986, Cenker was a crew member on the twenty-fourth mission of NASA's Space Shuttle program, the seventh flight of Space Shuttle Columbia, designated as mission STS-61-C. Cenker served as a Payload Specialist, representing RCA Astro-Electronics. This mission was the final flight before the Challenger disaster, which caused the Space Shuttle program to be suspended until 1988, and impacted NASA's Payload Specialist program for even longer. As a result, Cenker's mission was called "The End of Innocence" for the Shuttle program. Following the completion of his Shuttle mission, Cenker returned to work in the commercial aerospace field. Since his flight, he has made numerous public appearances representing NASA and the Shuttle program, in the United States, as well as internationally.

Early life and education Cenker was born on November 5, 1948, and raised in Menallen Township, Pennsylvania. He started his education at St. Fidelis College Seminary in Herman, Pennsylvania, leaving in 1962. In 1970 Cenker enrolled at Penn State University where he earned a Bachelor of Science degree in aerospace engineering. He continued his studies at Penn State and earned a Master of Science degree in 1973, also in aerospace engineering. Cenker earned a second Master of Science degree in electrical engineering from Rutgers University in 1977.

Pre-spaceflight career Cenker worked for 18 years at RCA Astro-Electronics and its successor company GE Astro Space. Cenker worked on hardware design and systems design concerning satellite attitude control. He also worked on in-orbit operations, as well as spacecraft assembly, test, and pre-launch operations. He spent two years on the Navy navigation satellite program, but spent most of his career working on commercial communications satellites.

Cenker's positions included integration and test manager for the Satcom D and E spacecraft, where he was responsible for all launch site activities. He also served as spacecraft bus manager on the Spacenet/GStar programs. He was responsible for ensuring the spacecraft could interface with multiple rockets, including the Delta, Space Shuttle, and Ariane launch vehicles.

Spaceflight experience

As an incentive for a spacecraft owner to contract with NASA to use a Shuttle launch instead of an unmanned, commercial launch system, NASA permitted contracting companies to apply for a payload specialist seat on the same mission.
