I continue with my history of the space race week by week through the eyes of My Weekly Reader. Both of these are from the 2nd grader edition.
From Wikipedia: ANNA 1B (acronym for "Army, Navy, NASA, Air Force") was a United States satellite launched on October 31, 1962, from Cape Canaveral, on a Thor-Ablestar rocket. The mission profile involved ANNA serving as a reference for making precise geodetic surveys, allowing measurement of the force and direction of the gravity field of Earth, locating the middle of land masses and establishing surface positions.
