===STS-51B===
Van den Berg was a payload specialist on [[STS-51B]] ''Challenger'' (April 29 – May 6, 1985). STS-51B, the Spacelab-3 mission, was launched from the [[Kennedy Space Center]], [[Florida]], and returned to land at [[Edwards Air Force Base]], [[California]]. It was the first operational [[Spacelab]] mission. The seven-man crew aboard ''Challenger'' conducted experiments in crystal growth, drop dynamics leading to container-less material processing, and atmospheric trace gas spectroscopy. Solar and planetary atmospheric simulation, cosmic rays, and laboratory-animal, and human medical monitoring experiments were performed.<ref>{{cite news |title=Men and Monkeys Team Up on Shuttle – Spacelab Research Highlights Mission that Begins Monday |url=https://www.proquest.com/docview/276634927 |page=A1 |first=James |last=Fisher |date=April 28, 1985 |access-date=October 17, 2022 |newspaper=[[Orlando Sentinel]] |id={{ProQuest|276634927}} |via=[[ProQuest]]}}</ref>
