Allô la Terre… ici Mars
by P. Demerseman, R. Foster.
Landing successfully on July 4, 1997, the day of the 221th anniversary of Independance and the year of the100th anniversary of the discovery of the electron by J.J. Thomson, Mars Pathfinder is a new, brillant illustration of the capabilities of the radiowaves. Without efficient long range radio communication, this fruitful space mission would be unrealizable. Some data concerning telecommunications between the Lander and the Earth via the Deep Space Network are quoted, along with other data relative to the Rover-Lander RF link.
