The Most accurate measurement ever made for determining the size and shape of the earth has been completed. The program (see January 1969 EOS, p. 4) lasted four years and involved 32 nations. Processing of data will take another two years.
The program was conducted by NASA and the Departments of Defense and Commerce in cooperation with foreign nations.
