Anatoly Blagonravov helped create the Dryden-Blagonravov agreement,  announced at the United Nations on December 5, 1962. which called for cooperation on the exchange of data from weather satellites, among other joint activities.
After John Glenn's orbital flight, an exchange of letters between President John F. Kennedy and Soviet Premiere Nikita Khrushchev led to a series of discussions led by Blagonravov and NASA Deputy Director Hugh Dryden. Their talks in 1962 led to the Dryden-Blagonravov agreement, which was formalized in October of that year, the same time the two countries were in the midst of the Cuban Missile Crisis. The agreement was formally announced at the United Nations on December 5, 1962. It called for cooperation on the exchange of data from weather satellites, a study of the Earth's magnetic field, and joint tracking of the U.S. Echo II balloon satellite.
