"The first American to venture across the edge of space will take a brief but momentous trip sometime late this summer. A year or two later, he or one of his six colleagues will take another and even more exciting journey - the first orbital flight in Project Mercury. To put this first man up and bring him safely down again is a matter of top priority effort today in the National Aeronautics and Space Administration, the nation's civilian agency for space. The national importance of Mercury is shown by the fact that it has been assigned a "DX priority" for scarce materials. Only a half dozen other projects share this super-urgent classification."
