Note: THE CACHE IS NOT LOCATED AT THE LISTED COORDINATES. Without much of the work done by the scientists and engineers included in the cache name, the accomplishments of the specific people associated with this puzzle likely would not have occurred. NOTE: the formula has been modified from that of the original listing.

The cache can be found at the following location: N 30 10.ABC W095 32.DEF, where; A = the number of letters in the last name of the last American to fly solo on an orbital space mission, one that proved to be the last of the Mercury space missions, B = The number of letters in the middle name of the fourth American in space, C = The number of times Alan Shepard flew into Space, D = the number of letters in the first name of the first human to ORBIT the earth, E = The number of times humans have orbited Mars, and F = The number of letters in the last name of the first American to orbit the earth. All answers are associated with rocket-based space programs. As a check of your answer: A+B+C+D+E+F = 22.
