As a result, he was invited to present a paper at the Congress of the International Astronautical Federation (London 1959) in which he enunciated his theory of the functional regulation of space, later published in Vienna (1960), and which would be assumed by the majority of jurists.

[4] In 1961 he published his first book Introduction to International Cosmic Law, a revised and updated edition of his doctoral thesis, that years later was translated into English.

Modesto Seara Vazquez joined an international movement in favor of the Jews of the Soviet Union, as part of the Latin American Committee, defending the right to leave.

He was appointed general advisor of Canal 13 (public television) where he also wrote weekly comments about the international life in the Séptimo día program.

Apart from that he created a series of international reports named Paz y Conflicto which programs were The Impossible Peace (on the Middle East), April in Portugal (the carnation Revolution, in Lisbon, Portugal), They Will Not Kill Hope (about Chilean political life and the death of Salvador Allende), the New Empire (about the last years of the Iran of Shah Reza Pahleví), and so on.

The Technological University of the Mixteca opened its doors in 1990, with 48 students, five professors and two classrooms, in the middle of a land baptized by local humorists as "the Seara Desert".

[8] As a result, the students of the Technological University of the Mixteca routinely rank among the top nationally (according to CENEVAL's General Knowledge Exams), in the fields of computer engineering, electronics, industrial or business sciences.
