I want to know the answer to the following question:
Von Braun and his associates were sent to  United States Army's White Sands Proving Ground in what year?
All the background I'm provided with is that "From here, von Braun and his team would develop the Army's first operational medium-range ballistic missile, the Redstone rocket, that would, in slightly modified versions, launch both America's first satellite, and the first piloted Mercury space missions.". Is that enough to answer the question?
Answer: no
